Abstract

The invention provides a flame-retardant high-resilience polyurethane foam material is prepared from mixed flame retardants of PNX and other organic phosphates. The high-resilience polyurethane foam material prepared from the raw material composition is good in flame resistance and high in resilience rate, and can be used for automobiles or furniture.

Description

technical field [0001] The invention relates to a polyurethane foam material, in particular to a flame-retardant high-resilience polyurethane foam, which belongs to the field of polymers. Background technique [0002] At present, the heat insulating elastic material mainly adopts soft polyurethane foam material, which has the advantage of good elasticity and heat insulating effect. However, there are two very obvious defects in soft polyurethane: one is extremely flammable, and a large amount of toxic smoke will be produced during the burning process, which can easily cause people's suffocation and death. [0003] Adding flame retardant is an effective way to improve the flame retardancy of polyurethane foam. The traditional way to improve the flame retardant properties of coated polyurethane foam is to add organic halogen and phosphorus liquid flame retardants to the raw materials. Based on the mass of raw polyester as 100 parts, more than 25 parts of this type of flame r...
