Abstract
The invention discloses a flame-retardant sealing strip for an automobile. The sealing strip is prepared from block styrol copolymer, fatty group waterborne polyurethane dispersoid, polyamide wax thick liquid, water-base resin containing activated functional groups, polypropylene, calcium carbonate, an antioxygen, an anti-ultraviolet agent, antimonous oxide, an antiscorching agent CTP, phosphoric acid ester and a-tocopherol. The sealing strip is good in flexibility and high in plasticity, flame-retardant, and very suitable for the sealing strip of doors and windows of the automobile, and can be recycled and used circularly.
Description
?
Technical field
The invention belongs to automotive field, be specifically related to a kind of flame retardant automotive sealed strip.
Background technology
The sealed strip material that existing automobile adopts is mainly polyvinylchloride material, thermoset terpolymer EP rubber, silicon rubber and thermoplastic elastomer etc., and what wherein account for large absolutely number is polyvinyl chloride and thermoset terpolymer EP rubber material.There is the defects such as aging resistance is poor, thermo-labile, not environmental protection in PVC sealing strip, is assembled on automobile door and window and uses after certain time limit, will be aging under solar radiation, be full of cracks, do not have good sealing function.Thermoset EPT rubber packing bar is in preparation process, need to be through Banbury mixer banburying and very long baking oven sulfuration, gap produces, complex process, production process is long, consume energy high, facility investment is large, and environment is had to certain pollution, scrap rubber bar or the adhesive tape changing can not reclaim direct recycling, the same with damaged tire go out of use be deposited in outside, form " black pollution ", the material of this product does not have the plastic processing characteristics of heat of thermoplastic resin and can not make colored article etc. simultaneously.In addition, the sealed strip normal temperature good springiness of the thermoplastic elastomer material take SBS, SEBS as base material, but during high temperature, heat-resisting and weathering resistance is slightly poor,, there is easily aging problem in also deviation of elasticity simultaneously, and should not be used for the sealing of automobile door and window.
The ageing resistance of natural rubber is not good, easily aging and cracking, and the prepared sealed strip life-span is shorter.The sealed strip that these materials are made does not belong to environmentfriendly products, causes certain wasting of resources, environmental pollution, and under low temperature condition, snappiness is not good.
