Abstract
The invention relates to a halogen-free flame-retardant ABS engineering plastic, which belongs to the technical field of flame-retardant products, and comprises 804-816 parts of ABS resin by weight, 100 parts of phosphorus flame retardant by weight, 20-50 parts of nitrogen flame retardant by weight, 40 parts of flexibilizer by weight and 4-6 parts of antioxidant by weight. The halogen-free flame-retardant ABS composition proposed by the technical scheme has good processibility and fire retardance so that the halogen-free flame-retardant ABS composition can be manufactured into shells of various electrical appliances and exterior trimming parts of various automobiles.
Description
Technical field
The present invention relates to a kind of halogen-free flame retardant ABS engineering plastics, belong to the technical field of flame retardant products.
Background technology
ABS plastic has good thermotolerance, and impact and good processibility are widely used in automobile component, household electrical appliance and electronic devices and components.The material that is used for household electrical appliance and business automation equipment shell has fire-retardant requirement, adds halogen compounds usually so that flame retardant resistance to be provided.The cost-performance balance of halogenated flame retardant is good, adapt to wide, moderate cost, but may be harmful to environment.
For consideration to environmental protection, the whole world, particularly, more and more scrupulous to the use attitude of halogen-containing fire retardant material the electric production and supply merchant of West Europe and Japan, be reluctant in other words to adopt, more be difficult to obtain environmental mark.On its " Official Journal ", issued " some objectionable impurities instruction is used in restriction in the electric merit equipment " such as European Union on February 13rd, 2003 and (be called for short " RoHS instruction ", its substance is from July 1st, 2006, in the electric/electronic device product of newly putting on market, forbid or limit and use lead, mercury, cadmium, sexavalent chrome, Poly Brominated Diphenyl Ethers (PBDE) and Polybrominated biphenyl six kinds of objectionable impuritiess such as (PBB).China Ministry of Information Industry has also put into effect " electronics and IT products prevention and cure of pollution management method " in 2004, content and RoHS are similar.In addition, in fields such as IT communication, electronic apparatuss, extensively made (blue angel) environmental mark in TCO99 (95), the German blue sky of approval by the whole world at present, all strictness is forbidden containing the halogen flame retardant immunomodulator compounds in the material that uses.Now the non-halogen research of material has been become the main flow in the world.
ABS is difficult to accomplish the V-0 level owing to lack aromatic group on the molecular backbone chain with halogen-free flame retardants.In the world the non-halogen research of ABS is carried out for many years, is mainly used phosphorus flame retardant or inorganic combustion inhibitor, phosphorus flame retardant efficient height, addition is few, but the adding of organophosphorus makes material plasticizing, severe exacerbation the impact of material and heat-resisting; The inorganic combustion inhibitor flame retarding efficiency is low, and addition is big, though little to heat-resisting influence, have a strong impact on impact.
Summary of the invention
Purpose of the present invention aims to provide a kind of suitable halogen-free flame-retardant ABS composition of cost with excellent properties.
Goal of the invention of the present invention can be achieved through the following technical solutions:
This halogen-free flame-retardant ABS composition comprises: ABS resin 804-816 weight part, phosphorus flame retardant 100 weight parts, nitrogen flame retardant 20-50 weight part, toughner 40 weight parts, oxidation inhibitor 4-6 weight part.
Described ABS resin is the high-impact ABS of glue content 12-16%.Preferred substance law ABS is as 3504,3513 etc. of Shanghai high bridge petrochemical iy produced.Substance law ABS excellent property, price comparison is low, and the base material of making modified plastics has great advantage.
Described phosphorus flame retardant is a kind of among RDP (Resorcinol biphosphonate), BDP (dihydroxyphenyl propane biphosphonate) and the RDXP (RDP polymkeric substance).
Described nitrogen flame retardant is MC (trimeric cyanamide urate) and MPP (polyphosphoric acid melamine).
Described toughner is acrylic ester elastomer.
Described oxidation inhibitor is Hinered phenols primary antioxidant and phosphorous acid esters auxiliary antioxidant.
Halogen-free flame-retardant ABS composition according to above technical scheme proposes has good processibility and flame retardant resistance, so can be used as the shell of various electrical equipment and the exterior trimming parts of automobile.
Embodiment
The technical characterstic that the invention is further illustrated by the following examples, but described embodiment only is used to illustrate the present invention rather than restriction the present invention.
ABS resin and various additive melt extrude through twin screw extruder behind high mixer high speed mixing, and liquid flame retardant adds to reinforced through the hydraulic fluid side, just can get said composition through cooling granulation again, and technological temperature is 200-210 ℃.
