Description
[technical field]
The present invention relates to the high molecule plastic technical field, relate in particular to a kind of reinforced polypropylene compound material and preparation method thereof.
[background technology]
Polypropylene (PP) is one of five big general-purpose plastics, and density is 0.90g/cm
3, be that (only greater than polymethylpentene, density is 0.85g/cm to the existing resin second light macromolecular material
3).Performance is good, proportion is little, be easy to characteristics such as forming process because of it has, and is widely used in automotive industry, household electrical appliance, electronic instrument industry, the textile industry.
Yet because the mechanical property of PP resin is lower, tensile strength 30MPa, the flexural strength 36MPa that only has an appointment that only has an appointment wherein makes it be subjected to a certain degree restriction when need to be applied to some structural parts of holding capacity.This just requires to develop enhanced PP matrix material, significantly promote material mechanical property, have excellent toughness and smooth surface, to satisfy people's demand.
In the prior art, people have done a large amount of work when the production reinforced polypropylene compound material.Reinforced polypropylene compound material mainly is to add glass fibre and make in acrylic resin.But by studies show that, though significantly improve with glass fibre enhanced polypropylene matrix material mechanical strength, the surface floating fiber of material has had a strong impact on the visual appearance of material, and higher proportion also is unfavorable for reducing cost.People also attempt to replace glass to open dimension with hollow glass micropearl and come Reinforced Polypropylene, to improve the surface gloss of material, solve the floating fine tight problem that gets.Yet a ubiquitous problem is troubling everybody all the time, is exactly that hollow glass micropearl very easily breaks in the course of processing and to make material property get the increasing degree degree little, can't reach the enhanced effect.
Owing to traditional increase strong polypropylene composite material and can't satisfy product mechanical strength height, good toughness, low, the ganoid requirement of proportion simultaneously.Thereby develop a kind of good toughness, intensity height, shrink for a short time, and smooth surface, novel enhanced polypropylene material that proportion is low seem especially important.
[summary of the invention]
