| titleOfInvention | A kind of EVA sealing process of waterproof chain |
| abstract | The invention relates to the technical field of chains, in particular to an EVA sealing process for a waterproof chain. The sprockets include a tooth root and a tooth head, the tooth heads mesh with each other, and the empty groove between the tooth roots is filled with a first resin The upper and lower surfaces of the tooth root and the first resin are compounded with a second resin body, and the injection molding and sealing process steps: injection molding the zipper tape with EVA elastomer as the injection resin. In the present invention, through the injection molding process, the resin body is filled in the non-meshing parts of the chain teeth, that is, the hollow groove between the tooth roots, so as to achieve the effect of preventing water seepage. The body is filled into the upper and lower surfaces of the tooth root through the injection molding process to form a complete and continuous EVA elastomer that fully covers the tooth root. Therefore, the tooth root can be used as a positioning column to fix the position of the EVA elastomer, so that it is not easy to dislocate or fall off. Improves structural stability and also improves waterproof performance. |
