Abstract

The invention discloses a seat polyurethane foam material with high flame retardation, low volatility and small compressive residual variable. The seat polyurethane foam material comprises, by weight,40-60 parts of polyether polyol (PPG), 40-60 parts of polymer polyol (POP), 2.5-3.5 parts of distilled water, 0.8-1.2 parts of a cross-linking agent, 0.4-0.6 part of a gel catalyst, 0.15-0.19 part ofa foaming catalyst and 0.65-0.85 part of a surface stabilizer. The seat polyurethane foam material has the advantages of high flame retardation performance, high safety, low volatile matter content,environmental protection, high rebound rate, comfortableness, small compressive residual variable, good durability, short production cycle and high yield.

Description

technical field [0001] The invention relates to the field of polyurethane foam materials, in particular to a seat polyurethane foam material with high flame retardancy, low volatility and small compression residual variable, its preparation method and application. Background technique [0002] At present, China's high flame-retardant seat foam raw materials are made of ordinary flame-retardant polyether polyols, plus ordinary halogen flame retardants, or phosphorus-containing flame retardants, or melamine, or antimony trioxide. No matter what kind of flame retardant additives will cause other physical properties to be reduced, the effect of environmental protection, comfort and durability cannot be achieved, and the oxygen index can reach 28.5% at most. At present, the performance requirements of the seat foaming of the northern high-speed rail are as shown in Table 1: [0003] Table 1. Physical property requirements of polyurethane foam [0004] [0005] 2. The combust...
