Production technology for foaming car seat synthetic cotton

Abstract

The invention discloses a production technology for foaming car seat synthetic cotton. The production technology comprises the following specific flows that raw materials including compound polyether and isocyanate are fed to a material pumping room, and a material pumping pump is used for pumping the compound polyether and the isocyanate into respective standby storage tanks; an automatic supplementing system is used for automatically feeding the compound polyether and the isocyanate of the standby storage tanks into a working storage tank to be mixed, and a high-pressure pouring machine pours the compound polyether and the isocyanate into a pouring gun head; a spraying gun is used for uniformly spraying a mould releasing agent to a mould cavity of a synthetic cotton mould; a fixing part in the car seat synthetic cotton is installed into a synthetic cotton mould locating block; after an upper mould body and a lower mould body of the synthetic cotton mould are combined, the pouring gun head pours mixed liquid into the synthetic cotton mould for foam forming; foamed synthetic cotton semi-finished products are placed into a sealing space of a cell crushing machine, and internal cells of the synthetic cotton semi-finished products are subject to vacuum extrusion to be discharged out; and the synthetic cotton semi-finished products obtained after the cells are crushed are repaired, checked and put in storage finally. The process technology is simple, saves the production cost and is high in production efficiency.

Description

technical field [0001] The invention relates to the field of production technology of composite foam, in particular to a production technology of composite foam for automobile seats. Background technique [0002] Due to the different physical properties of the seat fabrics required by different customers, such as the hardness, density, tensile strength, and elongation of the fabrics, it is necessary to solve this problem by replacing or developing new suppliers, which increases the company's Warehousing, management, experiment and other expenses, various supplier raw materials are injected into the storage tank during the switching process, due to the difference in raw material additives, poor foaming is likely to occur, and the yield of foamed cotton is low; therefore, the research and invention of a A unified combined cotton foaming production process is of great significance. Contents of the invention [0003] The purpose of the present invention is to overcome the sho...
