Description

A kind of polyvinyl chloride flex foam and preparation method thereof
Technical field
The invention belongs to chemical material field, particularly a kind of polyvinyl chloride flex foam and preparation method thereof.
Background technology
Porous plastics also is sponge plastics.The resin of take has the plastics of countless micropores as the inside that main raw material is made.Light weight, thermal insulation, sound-absorbing, shockproof, corrosion-resistant.Arranged dividing of soft and hard.Extensively be used as thermal insulation, sound insulation, wrapping material and car and boat housing processed etc.
Porous plastics inside has the plastics of a lot of small pores.By mechanical process (carry out churned mechanicallyly passing into air or carbonic acid gas makes its foaming simultaneously) or chemical method (adding whipping agent), make.Divide obturator-type and open cell type two classes.Pore in obturator-type is isolated mutually, and floatability is arranged; Pore in open cell type interconnects, without floatability.The resins such as available polystyrene, polyvinyl chloride, polyurethane(s) are made.Can make thermal insulation and sound-proof material, have many uses.
Porous plastics by a large amount of gas micropore dispersions in solid plastic and the family macromolecule material formed.The structural foam that grow up the sixties in 20th century, take core layer foaming, cortex not foam as feature, outer tough in hard, specific tenacity (in the intensity of unit mass) height, and material-saving replaces timber to be used for building and furniture industry increasingly extensively.Polyolefinic chemistry or radiation crosslinking foaming technology are achieved success, and the output of porous plastics is increased considerably.The porous plastics made through modified plasticss such as blend, filling, enhancings, have better over-all properties, can meet the needs of various special purposes.The glass fiber reinforced polyester ammonia ester foamed plastic for example made with reaction injection moulding, as the structure unit of aircraft, automobile, computer etc.; And fill with hollow glass micropearl the porous plastics that polybenzimidazole makes, light weight and high temperature resistant, for spacecraft.
Porous plastics is more in the market, but it is actually rare to have an extraordinary product shock-resistant, that return rate is high, tensile strength is large, chemical stability is good.
