Description
Technical field
The present invention relates to technical field of macromolecules, be specifically related to a kind of reinforced polypropylene compound material and preparation method thereof.
Background technology
Roller washing machine becomes requisite in modern society already, and the steel ladle of roller washing machine is mainly to make as fiber glass reinforced polypropylene, talc powder filled polypropylene with modified plastics, and contemporary roller washing machine is characterized as axle with ultra-thin and large capacity, two of high rotating speeds especially, so require its modified plastics resin will possess the features such as intensity is large, toughness is high, easy-formation, product any surface finish.
Polypropylene (PP) is a kind of crystal formation thermoplastic resin of high comprehensive performance, has the features such as nontoxic, tasteless, density is little; Its intensity, rigidity, hardness and thermotolerance are all better than low pressure polyethylene, can be about 100 ℃ uses; There is good electrical property and high-frequency insulation simultaneously and be not subject to humidity effect, but under cold condition, can become fragile, not wear-resisting, easily aging.Polypropylene is suitable for making common mechanical part, corrosion-resistant part and insulating part.The organic solvents such as common acid, alkali work hardly to it, can be used for tableware.But common PP intensity and toughness all do not reach roller washing machine water containing barrel and in high rotating speed, large capacity, full load situation, act on the requirement of the power on axis, so must just can make polypropylene reach its requirement through modification.
Fiber glass reinforced polypropylene is on the basis of original pure PP, adds glass fibre and other auxiliary agent, thereby improves the use range of material.General, most glass fiber reinforced materials is multiplex on the structural parts of product, it is a kind of Structural Engineering material, there is high strength, high rigidity, the features such as low contraction, when glass fiber content reaches certain limit, even can partly substitute iron and steel, but aspect toughness but relatively polypropylene reduce a lot, under high rotating speed high load condition, be easy to produce phenomenon of rupture and cause danger.And polypropylene is after being used glass to strengthen, it is apparent loses original glossiness and becomes coarse; It is can become very obvious that glass lines is greater than 15% at glass fiber content, and the glass fiber material that the major part that different household laundry machine cylinder steel ladle is used strengthens for 20%-30% left and right glass.
summary of the invention
For overcoming the deficiencies in the prior art, the invention discloses reinforced polypropylene compound material of a kind of high strength, high tenacity, low floating fibre and preparation method thereof.
The reinforced polypropylene compound material that the inventive method makes, by polyacrylic modification, has improved toughness and rigidity that original glass strengthens PP, and floating fine phenomenon also greatly reduces.
Technical scheme of the present invention is: a kind of reinforced polypropylene compound material, consists of by weight following raw materials according:
