Description

technical field [0001] The invention relates to a manufacturing equipment of a polyurethane sponge, in particular to a manufacturing equipment of a slow-rebound polyether polyurethane sponge. Background technique [0002] Slow resilience polyether polyurethane sponge is usually prepared by mixing polyol, isocyanate, foaming agent, surfactant, etc., and heating and foaming. The series of processes are quite complicated, which requires reasonable manufacturing equipment. In order to improve its production efficiency and reduce production costs. [0003] Existing rigid polyurethane foam molding foaming devices such as CN101544777B (2011-8-24) and the disclosure of molds for manufacturing foamed plastics CN2834871Y (2006-11-8), however, do not involve soft polyurethane sponges, especially slow rebound A report on the manufacturing equipment of polyether polyurethane sponge. Contents of the invention [0004] The object of the present invention is to provide a kind of manufac...
