Abstract
The invention provides a flame-retardant antistatic PA6 composite material comprising following ingredients, by weight: 100 to 300 portions of PA6, 10 to 20 portions of ethylene vinyl acetate copolymer, 10 to 20 portions of conductive carbon black, 30 to 50 portions of organic phosphate, 20 to 40 portions of melamine urate, 10 to 30 portions of phosphate ester salt, 5 to 15 portions of an anti-oxidant, 5 to 10 portions of a nucleating agent, 20 to 40 portions of a compatilizer and 5 to 15 portions of a lubricant. The flame-retardant antistatic PA6 composite material of the invention possesses both long-term antistatic properties and excellent mechanical properties.
Description
Technical field
The invention belongs to polymeric material field, be specifically related to a kind of flame-retardant and anti-static PA6 matrix material.
Background technology
Polyamide (PA) is commonly called as nylon, is one of principal item in the engineering plastics, and DuPont company developed the PA66 fiber first in 1938, and this is the earliest synthon in the world, and nineteen forty-one, the said firm developed first injection stage PA66 trade mark.The basic kind of PA has tens at present, and consequent modification kind reaches over thousands of.In actual applications, PA6 be output maximum in the PA series, consumption at most, purposes one of kind the most widely.
Along with use department to the more requirement of Gao Gengxin of material, and the ratio of performance to price of PA6 and Other Engineering plastics competition, the development priority of Polyamide Engineering Plastic mainly is the exploitation of existing kind is particularly carried out alloying, high performance, become more meticulous and the customizations modification at the different purposes of PA6.Yet PA6 has certain combustibility and higher resistance, accumulates a large amount of static charges later on easily when contacting with other materials or material surface or rubbing.Static discharge be will cause when serious, fire, blast caused.This largely limited its in the colliery, the application in field such as chemical industry equipment, workshops accessory, electronic apparatus.Therefore develop the flame-retardant and anti-static PA6 of high comprehensive performance, have great significance for enlarging the PA6 range of application and increasing its added value.
Summary of the invention
The purpose of this invention is to provide a kind of have long-term antistatic property and the superior flame-retardant and anti-static PA6 matrix material of mechanical property.
A kind of flame-retardant and anti-static PA6 matrix material, comprise following raw material by weight: PA6100～300 part, 10～20 parts of ethylene vinyl acetate copolymers, 10～20 parts of graphitized carbon blacks, 30～50 parts of organophosphates, 20～40 parts of trimeric cyanamide urates, 10～30 parts of phosphate ester salts, 5～15 parts in oxidation inhibitor, 5～10 parts of nucleators, 20～40 parts of compatilizers, 5～15 parts of lubricants.
Described PA6 viscosity is 2.4～3.2.
Described compatilizer is maleic anhydride graft POE, EPDM, a kind of among the PP.
Described lubricant is a kind of in lipid acid, stearates, the lipid acid amine.
