Abstract
The invention relates to an environment-friendly flame retardant polybutylene terephthalate composite material, and belongs to the technical field of high molecular materials. The composite material comprises the following raw materials in parts by weight: 77-85 parts of polybutylene Terephthalate resin, 15-24 parts of polyamide resin, 8-14 parts of olefin resin, 5-11 parts of a compatilizer, 22-31 parts of a fire retardant, 0.6-1.3 parts of an antioxidant, 0.5-0.8 parts of lubricant and 0.8-1.6 parts of carbon black. Through tests, the environment-friendly flame retardant polybutylene terephthalate composite material provided by the invention has the following performance indexes: the tensile strength is 95-118MPa, the bending strength is 170-205MPa, the notch impact strength is 11-15 kj/m<2>, and the fire resistance reaches V-0(UL-94-V-0-3.0). As no halogen is contained in the formula, the composite material has an ideal environmental friendliness property.
Description
Technical field
The invention belongs to technical field of polymer materials, be specifically related to a kind of polybutylene terephthalate alloy composite materials of environmental protection flame retardant.
Background technology
Polybutylene terephthalate has intensity and surface hardness height, good electrical property and characteristics such as high temperature resistant, is a kind of engineering plastics of high comprehensive performance, is widely used in automobile, electronic apparatus box mechanical manufacturing field.Along with the raising of people's living standard, to the fire-retardant requirement of material also corresponding raising, make the flame retardant properties of present material be satisfied with people's requirement.In order to improve flame retardant resistance, do not stint usually and add halogen or antimony compounds, yet these materials are easy to generate smog when burning on the one hand, make the rescue difficulty; Along with after goods abandon, can be formed with the harmful substances diffusion on the other hand, cause water body or environmental pollution, in view of this, be necessary to be improved.
Summary of the invention
Task of the present invention is to provide a kind of helping to strengthen intensity and be of value to the polybutylene terephthalate alloy composite materials that ensures desirable fire-retardant and environment amenable environmental protection flame retardant.
Task of the present invention is finished like this, a kind of polybutylene terephthalate alloy composite materials of environmental protection flame retardant, and its raw material by following parts by weight is formed:
In one embodiment of the invention, described polybutylene terephthalate resin refers to that fusing point is at 230 ℃ polybutylene terephthalate.
In another embodiment of the present invention, described polyamide resin is fusing point at 230 ℃ polyamide 66 resin.
In yet another embodiment of the present invention, described olefin resin is fusing point at 170 ℃ Co-polypropylene resin.
In another embodiment of the present invention, described compatilizer is the polyamide 66 resin of maleic anhydride graft.
Also have among the embodiment of the present invention, described fire retardant is the melamine poly-phosphate.
More of the present invention and among embodiment, described oxidation inhibitor is tricresyl phosphite (24-di-tert-butyl-phenyl) ester.
In of the present invention and then embodiment, described lubricant is erucicamide.
Of the present invention again more and among embodiment, described carbon black is the carbon black that channel process is produced.
The polybutylene terephthalate alloy composite materials of environmental protection flame retardant provided by the invention has following performance index after tested: tensile strength 95～118MPa, flexural strength 170～205MPa, notched Izod impact strength 11～15kj/m
