Description
Technical field
The present invention relates to the modified high-molecular field of new, be specifically related to a kind of high-performance fire-retardant polymer PC/ABS alloy.This material is widely used in the fields such as automobile, electronic apparatus and household electrical appliance, as making component and the employed material of structural part.
Background technology
Polycarbonate (PC) is a kind of increasingly extensive engineering plastics of using, and it has mechanical property, thermal characteristics and the electrical property of comprehensive stability.But the price of PC is more expensive, mobile poor, processing temperature (melt temperature) height, and stress cracking resistance is poor, is difficult to make the large thin-wall goods, simultaneously, PC is to the breach sensitivity, and hydrolysis stability and solvent resistance are bad, and these defectives have limited its practical application to a great extent.
For PC, (ABS) is cheap for acrylonitrile-butadiene-styrene copolymer, excellent property, and the product surface glossiness is good, is easy to machine-shaping, but thermotolerance is relatively poor.PC and ABS blend then can be obtained good combination property, the alloy that cost performance is high.The PC/ABS alloy material is widely used in the shell of computer, printer, facsimile recorder etc., also is applied to aspect such as panel board, wheel cap in the automobile, also is widely used at aspects such as electric and home appliances.
PC/ABS is a kind of polyblend of excellent performance, and its performance and price belong between PC and the ABS, and it compares it, and to have melt viscosity low with PC, advantage such as processing characteristics is good.Therefore, the PC/ABS alloy material has the excellent comprehensive performance.The half-phase solution system of PC and ABS resin metal amorphous and amorphous.Because the solubility parameter of PC is different with the solubility parameter of ABS, both consistencies depend on the rubber content among the ABS, and when rubber content hanged down, both consistencies were better, and rubber content is when higher, and both consistencies are relatively poor.If will make alloy that better shock strength is arranged, to select the higher trade mark of rubber content for use when selecting ABS, make both solubility parameters differ greatly thus, caused PC and ABS consistency relatively poor.In order to improve both consistencies, effective means is to add compatilizer in system.And the selection of compatilizer is the key that solves power PC/ABS plastic alloy technology problem.In addition, along with developing rapidly of automotive industry, electric industry, household electrical appliance industry and infocommunications industry, not only the demand to plastic material increases substantially, and used plastics flame retardant properties has been proposed new requirement.Therefore, in high-performance refractory PC/ABS alloy, adopt which type of flame-retardant system, very big to the flame retardant properties and the feature of environmental protection influence of this alloy.
The PC/ABS alloy material that uses in fields such as automobile, electronic apparatus and household electrical appliance at present mainly relies on external import, and external major company takes to block to China at the technical elements of this novel material.Because research and development, the application of PC/ABS alloy are started late, present homemade PC/ABS alloy material also is not widely used in this field because overall performance is not high at home.Development along with the novel material utilisation technology, the PC/ABS alloy can be widely used in fields such as automobile, electronic apparatus, household electrical appliance, as automobile internal and external ornament spare, communication device (mobile phone shell, battery case), computer and perimeter equipment, fire prevention electric switch, socket panel series product, air-conditioning terminal box etc.Therefore research and develop the power PC/ABS alloy material of high comprehensive performance, the sound development for promoting China's new material industry has crucial meaning.
Summary of the invention
The present invention seeks to research and develop a kind of new high-performance fire-retardant polymer PC/ABS alloy material, to replace external like product in this high-end technology field.Wherein, mainly be to solve PC and ABS biphase compatibility problem, be beneficial to give full play to both advantages, select the novel halogen-free flame-retardant agent to reach the purpose of environmental protection simultaneously.
For achieving the above object, the technical solution used in the present invention is: a kind of high-performance fire-retardant polymer PC/ABS alloy, and composition of raw materials is:
