Embodiment 1

[0034] A special flame-retardant polyurethane composite material for new energy vehicles is made of the following components in parts by weight:

[0035]

[0036]

[0037] The polyol A component is a mixture of polyether polyol and small molecule diol; the polyether polyol is a polyether diol, and the polyether polyol is a polytetrahydrofuran diol (PTMG) polymer; Described small molecule dihydric alcohol is butanediol;

[0038] The polyol A component is composed of the following components by mass percentage: polyether polyol 90-95%, small molecule diol 2-8%;

[0039] The number of the polyether polyols is that the molecular weight is 2000-3000, and the density is 0.962 g / mL.

[0040] The catalyst-1 is an amine catalyst; the catalyst-2 is an organometallic catalyst.

[0041] The P-based flame retardant is ammonium polyphosphate.

[0042] The isocyanate component B is a mixture of polyether polyol, polycarbon polyol and diphenylmethane diisocyanate (MDI), the polyether...

Abstract

The invention provides a special flame-retardant polyurethane composite material for a new energy automobile. The special flame-retardant polyurethane composite material is prepared from the following components in parts by weight: 100 parts of a polyol component A,-10.2-0.4 part of a catalyst,-20.2-0.4 part of a catalyst, 20-40 parts of a P-series flame retardant, 10-20 parts of an Al (OH) 3 flame retardant and 100-110 parts of an isocyanate component B. The invention further provides a preparation method of the flame-retardant polyurethane composite material. According to the flame-retardant polyurethane composite material special for the new energy automobile, through the synergistic effect of a solvent-free polyurethane foaming technology and an environment-friendly flame retardant, the problem that polyurethane is inflammable is solved; the environment-friendly concept that the flame retardant does not contain halogen does not affect the reaction among the components; the design concept of light weight of new energy can be achieved, the GB8410 flame retardant test of the product reaches the A-0 level, and the residual flame time is less than or equal to 10s; and the flame-retardant performance requirement of the automotive interior is met. The invention also provides a preparation method of the special flame-retardant polyurethane composite material for the new energy automobile.

Description

technical field [0001] The invention relates to the technical field of polyurethane, in particular to a special flame-retardant polyurethane composite material for new energy vehicles and a preparation method thereof. Background technique [0002] At present, the traditional car leather is basically polyvinyl chloride (PVC) leather, solvent-based polyurethane leather and a small amount of polyolefin thermoplastic elastomer (TPO), except for a small number of high-end cars that use genuine leather. PVC / TPO needs to add a lot of plasticizers and other additives in the production process, and the products have defects such as odor, unenvironmental protection, and plasticizer precipitation; solvent-based polyurethane leather has excellent performance, but its production process is seriously polluted and contains a large amount of harmful to human body of N,N-dimethylformamide (DMF) solvent. [0003] Polyurethane material is an organic high molecular polymer composed of carbon-c...
