Description
Technical field:
The present invention relates to but be not limited to roof of the vehicle polyurethane foam production technical field, specifically a kind of vehicle top
Canopy the PU cystosepiment of low plasticization temperature and production technology thereof.
Background technology:
The synthesis of polyurethane bulla block, be by a certain proportion of A material with B expect mix, agitated after in the casing of definite shape
Free foaming is made.In whole foaming process, because isocyano and the hydroxyl in polyhydric alcohol and water generation chemical reaction, put
Go out substantial amounts of heat, and because the heat-insulating property of polyurethane foam excellence, cause steeping nearly 200 DEG C of block internal temperature.Although this
High temperature can well promote the carrying out of chemical reaction, but under high temperature, side reaction also can increase, and causes VOC content to increase.
Automotive interior roof typically use PU cystosepiment (hereinafter referred to as PU plate) as framework material, by various adhesives
It is combined with each other by hot pressing with glass fibre, non-woven fabrics, fabric etc..In the whole course of processing, each in order to preferably obtain
Planting shape and the automotive interior roof of excellent performance, general heating-up temperature is both greater than 200 DEG C.Although post bake can make PU plate
In small-molecule substance volatilization, but the side reaction under high temperature in aerobic environment still can be carried out, and causes VOC content to increase, with
Time cause the waste of the energy.
VOC is the english abbreviation of VOC (volatile organic compounds).VOC is to human body
Health has tremendous influence, when the VOC in room reaches finite concentration, in the short time people can feel headache, Nausea and vomiting,
Weak etc., there will be tic, stupor time serious, and the liver of people, kidney, brain and nervous system can be hurt, cause memory
The serious consequences such as power goes down.
Summary of the invention:
It is an object of the invention to overcome the deficiency of above-mentioned prior art, and provide the PU of the low plasticization temperature of a kind of roof of the vehicle to steep
Foam plate.
It is a further object of the present invention to provide the production technology of the PU cystosepiment of the low plasticization temperature of a kind of roof of the vehicle.
The side reaction that present invention mainly solves in the existing PU cystosepiment course of processing still carries out, and causes VOC content to increase
Height, thus the problem affecting health of human body.
