In this paper, a comparative study on the surface modification of diamond in five groups of experiments was carried out, namely: silane series coupling agent for diamond surface modification, diamond surface nickel plating and silane series coupling agent modification, aluminum-titanium composite series The surface of the diamond is modified by a joint agent, and the surface of the diamond is coated with titanium and modified by an aluminum-titanium composite coupling agent.
The substrate used in this experiment was of the same quality as the resin binder.
I. Silane coupling agent modified silane coupling agent as a silicon compound with unique structure, which bridges the gap between inorganic and organic materials, improves the defects of many materials, and develops the anti-corrosion technology of silane reagent on metal surface. The direction has been initially formed, and its advantages are obvious. The general structural formula of the silane reagent is: YR-SiX3, which: X is a hydrolyzable group bonded to a silicon atom, such as a chloro group, a methoxy group, an ethoxy group, an acetoxy group or the like; and Y is an organic functional group such as an amino group. , an epoxy group or the like; R is a carbon chain having a saturated or unsaturated bond. Therefore, when it is distributed at the interface between the inorganic substance and the organic substance, it acts as an "emulsifier" between interfaces which have no affinity with each other and are difficult to be compatible. Since the interface phenomenon is very complicated, a single theory is often difficult to fully explain, and there are many explanations for the mechanism of action of the silane reagent at the interface.
The theories that have been proposed about the behavior of silane reagents on inorganic surfaces mainly include chemical bonding theory, physical adsorption theory, hydrogen bond formation theory, and reversible equilibrium theory. A mainstream theory holds that when the inorganic substance does not have a hydroxyl group on the surface, such a coupling agent is difficult to exert a corresponding action or effect. Diamond is arranged by its own atomic structure, and its surface is very inert. From this point of view, the general coupling agent has a limited effect on it. However, in view of the complexity of the mechanism of action of the silane reagent at the interface, such tests still have some value; In organic systems, most molecules have specific functional groups that exhibit the properties of the polymer. The silane coupling agent chemically reacts with the polymer organic uterine energy group to produce a coupling effect. It is generally considered that the silane coupling agent is most effective for the thermosetting resin accompanying the chemical reaction in the curing process, and for the lack of reactivity and polar groups. The thermoplastic resin of the group is inferior. Therefore, the resin used in this experiment is a thermosetting resin.
Sample I: diamond is RVD280#, silane coupling agent grade: 3-aminopropyltriethoxysilane KH-550, step: adding a certain amount of silane KH-550 to the modified resin adhesive, Mix well and then apply rubber sand.
Sample II: The production procedure was the same as that of Sample I, except that the diamond surface was nickel plated. Source: Specially customized.
Second, the aluminum-titanium composite coupling agent modified aluminum-titanium composite coupling agent has the characteristics of titanium-based and aluminum-based coupling agents, and the coupling agent effect is better than single titanate, aluminate and both. Mixture, this product can greatly improve the filling amount of inorganic filler in the resin, significantly improve the physical and mechanical properties such as tensile strength, impact strength, elongation at break, reduce system viscosity and improve processing performance. Moreover, due to the action of the organic functional group, the bonding force between the filler and the binder is greatly improved, and the strength of the composite system is enhanced.
Sample III: Diamond is RVD280#, aluminum-titanium coupling agent grade: aluminum-titanium composite coupling agent LD, step: adding a certain amount of aluminum-titanium composite coupling agent LD to the modified resin adhesive, mixing evenly Then apply glue to the sand.
Sample IV: The fabrication procedure was the same as that of Sample III, except that the diamond surface was plated with titanium. Source: Specially tailored.
Sample V: This sample is the original sample for comparative test. The preparation method is the same as above. The diamond is RVD280#, the surface is not plated, and it is modified without adding any coupling agent.
Third, the comparative test The comparative test was carried out on the universal belt machine 2M5415A, and the parameters were the abrasion amount of the belt when grinding the same kind of jade jade 20g. Abrasive belt wear is based on the overall mass reduction of the belt before and after grinding, including the wear of the adhesive and the wear of the diamond. The following table shows the mass loss of 5 groups of samples:
Sample Number Sample I Sample II Sample III Sample IV Sample V
Mass reduction (g) 0.54 0.49 0.58 0.39 0.57
IV. Results and discussion First of all, it is necessary to explain that the test is purely to investigate the effect of diamond surface modification on the performance of diamond coated abrasive products. The performance is only the wear of diamond abrasive belt under the same processing conditions. The above data are only compared. significance. Strictly speaking, this method cannot be used as a test method for measuring the belt wear ratio.
It can be seen from the above data comparison that the performance of the abrasive belt obtained by the sample IV, that is, the surface of the diamond coated with titanium and the aluminum-titanium composite coupling agent, is significantly improved compared with the other ones; the silane, aluminum-titanium composite coupling agent The surface modification of diamond has little effect on the performance of diamond sand belt. Nickel plating on diamond surface has certain effect on surface modification of silane series coupling agent, but it may increase the surface area and adhesive of diamond with nickel plating on diamond surface. It is related to its holding power, and whether the coupling agent plays a role in it needs further test and verification.
At the same time, the author believes that the surface of diamond coated with corundum is modified by aluminum zirconium coupling agent, and the surface of diamond is coated with titanium dioxide and modified with titanate coupling agent. It is also worthy of similar tests to test its performance. Impact. Because the two surface plating products are temporarily unavailable, the test is temporarily unavailable.

Use
Superhard material coated abrasives are a kind of flexible flexible abrasives that use synthetic diamond or cubic boron nitride as abrasives and bond them to the substrate by adhesive. They can also be classified as super The category of hard materials. With the continuous development of modern machining and the emergence of various new materials, the processing precision and surface roughness are getting higher and higher, and the corresponding advanced grinding technology and abrasive tools, especially coated abrasives, are becoming more High efficiency, long life and ultra-precision development. To this end, the development and use of superhard material coated abrasives has quietly emerged, and has been applied in the special processing fields of difficult-to-machine materials such as automobile industry, electronics industry, glass processing, gem processing, stainless steel, and hardened steel. Like ordinary abrasive coated abrasives, the factors affecting the performance of superhard materials coated abrasives are mainly substrates, adhesives and abrasives, but due to the strong wear resistance and high life of superhard material coated abrasives, only in Articles on substrates and adhesives may not fully meet the needs of product performance. In this paper, the common cloth base is used as the substrate, the resin adhesive is used as the binder, and the diamond abrasive is used as the research object. The influence of different diamond surface treatment methods on the product performance is compared, and the development of the superhard material coated abrasive products is developed. Provide a train of thought, and at the same time, the bigger purpose is to throw a brick into the jade, hoping to get better ideas and methods for the development of such products in the industry.
