Description
Technical field
The present invention relates to a kind of polymer composite, be specifically related to a kind of high heat-resisting, enhancing, toughening composition that is used for the automobile instrument framework.
Background technology
For many years, the whole world automobile enterprise matrix material that is used for the automobile instrument framework mainly contains three classes: glass-reinforced polypropylene, polystyrene/polyhenylene ether (PS/PPO) intermingling material and glass fibre reinforced styrene-copolymer-maleic anhydride (SMA resin).Owing to having good thermotolerance, dimensional stability, processing fluidity and lower cost, glass fibre reinforced styrene-copolymer-maleic anhydride (SMA resin) becomes the strongest rival in this three classes matrix material.The styrene-maleic anhydride copolymer of whole world maximum (SMA resin) manufacturer Nova chemical company is declared, in all Americanized instrument panel brackets, have 2/3rds all to adopt glass fibre reinforced styrene-copolymer-maleic anhydride (SMA resin) material molding to form.
Practical both at home and abroad at present SMA is in the majority with the terpolymer that contains rubber component, the SMA resin of terpolymer is the random copolymers of graft phenylethene-maleic anhydride on rubber, it has excellent comprehensive physical and mechanical property and processing characteristics, at first by the ARCO company Development and Production of the U.S. and be applied, internals, household electrical appliance, office appliance of automobile etc. have been widely used in.At present domesticly can't produce the SMA terpolymer that contains rubber component, but the existing certain throughput of the binary copolymerization SMA that does not contain rubber, this resinoid has better heat-resisting and physicals, but fragility is big, be used for the automobile instrument framework, must be through toughening modifying or glass fibre reinforced modified.
Modification for the SMA that strengthens toughness reinforcing binary copolymerization, many patent reports have been had both at home and abroad, the methods of simple blend that adopt are carried out more, this working method has characteristics easy and simple to handle, easy to implement, as long as adopt suitable twin screw extruder just can finish modification work, the core technology of developing toughness reinforcing enhancing SMA material is the selection of toughner.Introduced with MBS, SAN and glass fibre in the patent of CN1450112A and added simultaneously, improved merely and strengthen the low problem of binary copolymerization SMA material impact intensity with glass fibre.CN1388170A then is by strengthening the ABS that adds MBS and high rubber content among the SMA at glass fibre, comprehensively improving the overall performance of material.
Summary of the invention
The object of the present invention is to provide a kind of certain toughness of having of automobile instrument framework and inflexible enhancing toughening composition of being used for.
The enhancing toughening composition that the present invention proposes is with phenylethylene-maleic anhydride binary random copolymer (SMA) and plasticized modifier blending and modifying, and with glass fibre blend enhancing modified, the weight proportion of its component is as follows simultaneously:
Common preferred preferably of component
100 parts 100 parts 100 parts of SMA
MBS 0-20 part 5-18 part 5-15 part
EBG 0-30 part 3-25 part 5-22 part
POE 0-20 part 0-15 part 0-10 part
Glass fibre 5-40 part 5-35 part 10-30 part
In the above-mentioned component, SMA is an atactic styrene-maleic anhydride copolymer, and is heat-resisting fine because of not containing rubber constituent, but toughness is relatively poor, not shock-resistant.
In the above-mentioned component, MBS is the terpolymer with methyl methacrylate-butadiene-styrene of shell-core structure, is generally used for toughening polyvinyl chloride, for example the BTA-751 of Wu Yu chemical industrial company; Also comprise the MBS that is specifically designed to engineering plastic modification, as the E-920 of ATOFINA company production.
In the above-mentioned component, EBG is ethylene-propylene acid butyl ester-glycidyl methacrylate terpolymer, and it is toughness reinforcing that it is mainly used in ABS, as the Elvaloy PTW of E.I.Du Pont Company.
In the above-mentioned component, POE is ethylene-alpha-olefin two membered copolymers, and wherein alhpa olefin is butylene, octene or hexene, the ethylene-octene copolymer Engage 8150 of typical products such as Du Pont-DOW chemical company.
A kind of preparation process at the described enhancing toughening composition that is used for the automobile instrument framework is as follows: at first be that 100 parts of SMA, MBS 0-20 part, EBG 0-30 part, POE 0-20 part each component mix at mixer with weight part, mixing time was generally 3-5 minute, then the material that mixes is added twin screw extruder, glass fibre 5-40 part adds from another spout of twin screw extruder, is prepared into the enhancing toughening composition.
Wherein, content of glass fiber control can reach requirement by adjusting screw speed and rate of feeding.
Prepared various modifying material are by the various desired products of plastic injection equipment moulding.
And superiority of the present invention is: owing to adopted the method for EBG and MBS or POE and usefulness to improve the impact property that glass fibre strengthens SMA, and make its resistance toheat remain on a quite high level, these three kinds of materials are the commercial multipolymer of production in enormous quantities, there are many companies to provide at present in the world, therefore wide material sources guarantee that high heat-resisting, toughness reinforcing, the enhancing SMA material developed can stablize production in enormous quantities.The toughness reinforcing SMA of the enhancing that makes by this method can meet the requirement of automobile instrument framework, is the important means of a kind of expansion SMA of practical simplicity.
Further specify the present invention by the following examples, yet the present invention should be not limited to the content that following examples are specifically expressed.
