Abstract

The invention relates to a polypropylene-modified polyamide composite which belongs to the technical field of macromolecular materials. The polypropylene-modified polyamide composite comprises the following ingredients in parts by weight: 25-31 parts of polyamide 66 resin, 4-8 parts of polypropylene resin, 2.3-3.6 parts of flexibilizer, 2.1-4 parts of compatilizer, 7-13 parts of fillers, 2-3 parts of glass beads, 0.3-0.8 parts of antioxidant, and 1.2-2.3 parts of carbon black. Through tests, the polypropylene-modified polyamide composite provided by the invention has the following performance indexes: the tensile strength is 112-130MPa, the bending strength is 170-200MPa, and the notched Izod impact strength is 12-15kj/m<2>.

Description

The polyamide compoiste material of polypropylene modification
Technical field
The invention belongs to technical field of polymer materials, be specifically related to a kind of polyamide compoiste material of polypropylene modification.
Background technology
Polymeric amide is the most widely used engineering plastic materials of a class, is widely used in fields such as automobile, electrical equipment, building.But phosphinylidyne-containing amine group in the polymeric amide molecular chain belongs to polarity, and the moisture absorption causes losing efficacy easily in wet environment easily.Polypropylene molecule is made up of hydrocarbon, and polarity is little, and moisture is had repulsive interaction.So utilize these characteristics of polypropylene, polyamide resin is carried out modification, the problem that solves the material moisture absorption has positive effect.
Summary of the invention
Task of the present invention is that a kind of intensity height that has, the polyamide compoiste material of the polypropylene modification of the characteristics that water-intake rate is low will be provided.
Task of the present invention is finished like this, a kind of polyamide compoiste material of polypropylene modification, and its raw material by following parts by weight is formed:
Figure BDA0000306225361
In one embodiment of the invention, described polyamide 66 resin is meant fusing point more than 210 ℃, and the limiting viscosity index is 2.4 polyamide 66 resin.
In another embodiment of the present invention, described acrylic resin is the Co-polypropylene resin, 160 ℃ of fusing points.
In yet another embodiment of the present invention, described toughner is high impact polystyrene.
In another embodiment of the present invention, described compatilizer is a toxilic acid bar grafted polypropylene.
Also have among the embodiment of the present invention, described filler is a nano-calcium carbonate.
More of the present invention and among embodiment, described glass microballon is a hollow glass micropearl.
In of the present invention and then embodiment, described oxidation inhibitor is tricresyl phosphite (24-di-tert-butyl-phenyl) ester.
Of the present invention again more and among embodiment, described carbon black is a furnace treated black.
The polyamide compoiste material of polypropylene modification provided by the invention has following performance index after tested: tensile strength 112～130MPa, flexural strength 170～200MPa socle girder notched Izod impact strength 12～15kj/m 2
