Abstract

The invention relates to the technical field of zipper tapes, and particularly relates to a polyurethane elastomer sealing process of a waterproof zipper tape. Each zipper tooth comprises a tooth root and a tooth head, the tooth heads are meshed with one another, empty grooves between the tooth roots are filled with first resin bodies, and second resin bodies are compounded on the upper surfaces and the lower surfaces of the tooth roots and the first resin bodies. According to steps of the injection molding sealing process, a polyurethane elastomer serves as injection molding resin to conduct injection molding on the zipper tape. Through the injection molding process, the non-meshing parts of the zipper teeth, namely, the empty grooves between the tooth roots, are filled with the resin bodies so as to achieve the water seepage prevention effect, meanwhile, in order to improve the embedding stability of the resin bodies and further improve the waterproofness, the resin bodies are integrally filled into the upper surfaces and the lower surfaces of the tooth roots through the injection molding process, and the complete and continuous polyurethane elastomer completely covering the tooth roots is formed, so that the tooth roots can fix the position of the polyurethane elastomer as a positioning column, the polyurethane elastomer is not prone to dislocation or falling off, the structural stability is improved, and the waterproof performance is also improved.

Description

technical field [0001] The invention relates to the technical field of chains, in particular to a polyurethane elastomer sealing process for waterproof chains. Background technique [0002] A zipper is a connecting piece that relies on continuously arranged chain elements to merge or separate items. It is now widely used in clothing, bags, tents, etc. Due to the intermeshed nature of the chain elements, even when the zipper is in a closed state, there will be large gaps between the chain elements, so the waterproof effect cannot be achieved. The current waterproof structure used for zippers is generally simply to make a cloth tape on the back of the chain teeth. Although it can prevent water seepage to a certain extent, the water that penetrates is only absorbed by the cloth tape in essence, and the effect of preventing seepage is not achieved. The cloth strips on the back are also easy to get stuck on the chain teeth, and the user experience is not high. Contents of the ...
