Problems solved by technology

However, due to its own characteristics, it is difficult for a single filler to take into account the factors that affect the amount of abrasion such as crush resistance, hardness, and shape. Therefore, the improvement of the wear resistance of the coating film is limited during application. Poor and other shortcomings

Abstract

The invention provides abrasion-resistant agents. The abrasion-resistant agents are characterized by comprising modified inorganic fibers and nylon, the weight ration between the modified inorganic fibers and the nylon is (1-30) : 100, the modified inorganic fibers are obtained by modifying inorganic fibers through nanofiller, the weight of the nanofiller accounts for 5-40 % of the total weight of the nanofiller and the inorganic fibers, the weight of the inorganic fibers accounts for 60-95 % of the total weight of the nanofiller and the inorganic fibers, and the surface of the modified inorganic fibers is covered by poly-dimethyl diallyl ammonium chloride. The invention further provides a preparation method of the abrasion-resistant agents. The abrasion-resistant agents integrate the advantages of the nylon, the inorganic fibers, and the nanofiller, and have high abrasion-resistant performance. When the abrasion-resistant agents are added into coating, a coating film has good abrasion-resistant performance, and is protected from abrasion.

Description

technical field [0001] The invention relates to a polymer compound composition, in particular to an anti-wear agent and a preparation method thereof. Background technique [0002] Coating film (also known as paint film) is a solid continuous film formed by one or more coats of paint applied to a substrate. Since the coating film covers the surface of the substrate, it is inevitable that the coating film will be rubbed during use. Friction often leads to gradual wear of the coating film. After the coating film is worn, it will become thinner, exposed or even damaged, so that it will lose its protective effect and decorative effect on the substrate. Therefore, the coating film wear caused by friction is what people hope. Avoiding as much as possible, the wear resistance of the coating film has been paid more and more attention by people. [0003] Anti-wear agent is an additive that can improve the abrasion resistance of the coating film. After the anti-wear agent is added t...
