Polyurethane cushion and production technique thereof

Abstract

A polyurethane mat and its manufacturing process, which is composed of the following two parts: a. 40-70% polyether polyol, 25-55% polyester polyol, butanediol or / and ethylene glycol or / and propylene glycol Neopentyl glycol or / and hexanediol or / and diethylene glycol or / and dipropylene glycol 0.1-5%, stannous octoxide or / and dibutyltin dilaurate or / and bismuth isooctanoate 0.09-1.5%; b .Polyether polyol 30-60%, polyester polyol or / and polycarbonate diol 5-30%, isocyanate 30-60%, adipoyl chloride or / and phosphoric acid or oleic acid 0.001-0.1%, butanediol 0.3-5% of alcohol or / and neopentyl glycol or / and hexanediol, the above-mentioned percentages are by weight. Its production process includes batching, feeding into the mold, forming in the mold and trimming processes. It has the advantages of easy preparation, good product performance, low production cost, simple production process and large output. It is a very practical product. Promote apps.

Description

technical field [0001] The invention relates to a polyurethane cushion and a manufacturing process thereof. Background technique [0002] Most of the existing high molecular polymer mats (or pads, gaskets) are made of plastic (such as PVC) and rubber materials. They are generally made by one-time integral injection molding or vulcanization, and the products made are resistant to low temperature. Poor performance, easy to harden and crack, feel stagnant; and there are many production equipment, high energy consumption of equipment, high production cost, and many operating human factors, low daily output, and low operating safety factor, such as easy to be crushed and burned, so the operation The requirements are high; there are many technological processes for the production of finished products, which may easily cause the production environment to be dirty and smelly. Some raw materials (such as PVC) in close contact with the human body for a long time will also affect human...

Problems solved by technology

[0002] Most of the existing high molecular polymer mats (or pads, gaskets) are made of plastic (such as PVC) and rubber materials. They are generally made by one-time integral injection molding or vulcanization, and the products made are resistant to low temperature. Poor performance, easy to harden and crack, feel astringent; and there are many production equipment, high energy consumption of equipment, high production cost, and many operating human factors, low daily output, and low operating safety factor, such as easy to be crushed and burned, so the operation The requirements are high; there are many technological processes for the production of finished products, which may easily cause the production environment to be dirty and smelly. Some raw materials (such as PVC) in close contact with the human body for a long time will also affect human health. In addition, due to the nature of plastics, the product is easy to age, Poor wear resistance and short service life; more importantly, these products will not decompose naturally, and will seriously pollute the environment in the future, which will bring a great shadow to the current era of increasingly advocating protection of the world's environment
