PU polyether polyurethane

Abstract

The invention relates to the field of polyurethane products, particularly to a polyurethane material, more particularly PU polyether polyurethane. The PU polyether polyurethane includes following raw materials: polyether polyol, TDI, a silicone surfactant, a water foaming agent, MC and a composite catalyst. The polyether polyol includes PU polyether, a petroleum by-product polyether and polyol. The PU polyether is polyether polyol prepared by subjecting recovered sponge leftover bits and pieces to a reversible reaction. By the technical scheme, the sponge leftover bits and pieces are adopted in place of a part of petroleum polyether polyol in a traditional polyurethane material production process, thus relieving the sponge production cost pressure caused by increased prices of petrochemicals.

Description

technical field [0001] The invention relates to the field of polyurethane products, in particular to a polyurethane material. Background technique [0002] Polyurethane material (polyurethane sponge) is the abbreviation of polyurethane, the English name is polyurethane, it is a kind of polymer material. Polyurethane is an emerging organic polymer material, known as the "fifth largest plastic", and is widely used in many fields of the national economy because of its excellent performance. The product application fields involve light industry, chemical industry, electronics, textile, medical treatment, construction, building materials, automobile, national defense, aerospace, aviation and so on. [0003] Polyether polyol is the main raw material for the production of polyurethane sponge. The polyether polyol generally used in the production of polyurethane sponge is usually petroleum polyether polyol. However, the polyurethane made of petroleum polyether polyol has high stabi...

Problems solved by technology

[0003] Polyether polyol is the main raw material for the production of polyurethane sponge. The polyether polyol generally used in the production of polyurethane sponge is usually petroleum polyether polyol. However, the polyurethane made of petroleum polyether polyol has high stability and is naturally It is difficult to decompose in the state; making it non-degradable is not conducive to environmental protection and sustainable development

At the same time, as petrochemical energy reserves are decreasing day by day, the price of petrochemical products continues to rise, which also increases the cost of sponge production
