Description

A kind of high CTI value, high GWIT value environment-protection flame-proof fiberglass strengthen PP/PA1010 alloy material and preparation method
Technical field
The present invention relates to a kind of PP/PA1010 alloy material and preparation method thereof, specifically, is a kind of high CTI value, high GWIT value environment-protection flame-proof fiberglass enhancing PP/PA1010 alloy material and preparation method thereof.
Background technology
Nylon (Nylon), Chinese name polymeric amide, English name polyamide, be called for short PA, be on molecular backbone chain containing recurring amide radical group-[NHCO]-thermoplastic resin general name, its name is determined, as PA-6, PA-66, PA-1010, PA-610 by the carbonatoms that synthon is concrete.The degree of crystallinity of PA is high, fusing point is obvious; Surface hardness is large, abrasion performance, frictional coefficient are little, have self lubricity and sound-deadening properties; Low-temperature performance is good, has certain thermotolerance (can use below 100 DEG C); Nontoxic, odorless, not go rotten, have self-extinguishing, good weatherability, but dyeability is poor.PA1010, Chinese nylon 1010, is obtained through polycondensation by sebacic acid.PA1010 plastics are translucent, light and the crystallization shape white of hard, surface-brightening or micro-yellow particle, relative density and water-absorbent lower than PA6 and PA66, physical strength is high, impelling strength, wear resistance and self lubricity are good, winter hardiness is better than PA6, and fluidity of molten is good, is easy to forming process.PA1010 plastics also have good electric insulating quality and chemical stability, nontoxic, are insoluble to most of non-polar solvent, but are dissolved in intensive polar solvent.
Polypropylene, English name polypropylene, is called for short PP, molecular formula: (C 3h 6) n, be a kind of thermoplastic resin obtained by propylene polymerization.Isotatic polypropylene (isotaetic polyprolene), Atactic Polypropelene (atactic polypropylene) and syndiotactic polypropylene (syndiotatic polypropylene) three kinds is divided into by methyl arrangement position.PP is nontoxic, tasteless, and density is little, and intensity, rigidity, hardness thermotolerance are all better than low pressure polyethylene, can about 100 DEG C uses; There is good electrical property and high-frequency insulation not by humidity effect, be suitable for making common mechanical part, corrosion-resistant part and insulating part.The organic solvents such as common acid, alkali work hardly to it, therefore can be used for tableware.
PP/PA1010 alloy material combines the advantage of PP and PP1010 bi-material.
