Problems solved by technology

However, aluminum hand molds also have many disadvantages: first, the corrosion resistance is poor, and it is easy to corrode in the dipping environment; second, the surface is rough, making it difficult to remove the gloves from the mold, and it is easy to cause wear and tear on the finished gloves
[0004] In response to this problem, some manufacturers have proposed the idea of ​​using Teflon coating to protect the hand model, such as patent CN201120562258.2, but due to the low adhesion of Teflon products to aluminum alloys, after a period of use, the coating That is to say, it will fall off, and once the coating has leaks and falls off, it will fall off in a large area. Although this coating has made some progress in corrosion resistance compared with traditional hand molds, it is still very important in the production of hand molds. The use cycle is short and fragile in the process, which also causes the increase of product cost and the decrease of production efficiency

Abstract

The present invention relates to a coating, and particularly relates to a coating for protecting a hand mould, and a preparation method and an application thereof. The coating is prepared by: firstly, carrying out a reaction of novolac epoxy vinyl ester resins, carboxyl-terminated liquid nitrile rubber and polyphenylene sulfide to form a reactant, taking the reactant as a base resin, then adding a composite modifier to obtain a modified resin, and finally, adding a curing agent for curing, and obtaining the coating. The coating provided by the invention has excellent corrosion resistance, medium permeability resistance, thermal alteration resistance and temperature resistance, and has super adhesive force of up to 16 MPa with metal matrixes. Because of high corrosion resistance, temperature resistance and thermal shock resistance of the coating, the service life of the hand mould is prolonged from about 2 months of the conventional time to more than 5 months.

Description

technical field [0001] The invention relates to a coating, in particular to a protective coating for hand mold protection, a preparation method and application thereof. Background technique [0002] At present, there are many kinds of labor insurance gloves with different styles. Due to their excellent properties such as wear resistance, puncture resistance, acid and alkali resistance, grease, fuel and various solvents, dipped gloves have been widely used in automobile manufacturing, battery manufacturing, and fiberglass industries. , aircraft assembly and aerospace fields have been more and more widely used. [0003] Hand molds are used in the production process of gloves. Traditional hand mold base materials mainly include ceramic hand molds and aluminum alloy hand molds. Due to the strong rigidity and good heat dissipation performance of aluminum alloy hand molds, it has gradually replaced ceramic glove molds in most rubber dipping fields. However, aluminum hand molds a...
