Abstract

The invention discloses washing-resistant epoxy paint, and a preparation method and an application thereof. The washing-resistant epoxy paint is mainly composed of a component A and a component B according to a volume ratio of 3:1. The component A is compose of epoxy resin with epoxy equivalent of 450-500, epoxy resin with epoxy equivalent of 180-190, plasticized resin, an organic solvent, an adhesion-promoting agent, an auxiliary agent, wax powder, and a toner. The component B is composed of a modified aliphatic amine epoxy curing agent, a polyamide epoxy curing agent, a tertiary amine curing accelerator, and xylene. The washing-resistant epoxy paint provided by the invention is suitable to be used in metal zipper workpiece coating. The metal zippers processed with the coating treatment have the advantages of smooth surfaces and uniform color. A dried paint film has good enzyme solution resistance and excellent washing resistance.

Description

technical field [0001] The invention relates to the field of epoxy coatings, in particular to a washable epoxy coating and its preparation method and application. Background technique [0002] At present, in the garment accessories industry, more and more zipper pullers are made of zinc alloy materials. And because people's living standard improves day by day, also more and more higher to the requirement of clothing. In the clothing industry, the requirements for the washing resistance of zipper sliders are getting higher and higher. For the performance test of the water resistance of the zipper puller, some traditional test methods are to wash at 40°C for 30 minutes (refer to GB / T3921), but now many garment factories have raised the test standard to 4 hours at 60°C and then washed for 4 hours. Some garments are simulated to be washed 5 times (refer to GB / T8629). However, the washing resistance of existing zipper slider coatings is relatively poor, and the passing rate of...
