Technical field
The present invention relates to technical field of polymer materials, be specifically related to a kind of low-temperature impact-resistant extrusion-grade ABS alloy material.
Background technology
ABS resin is with propylene cyanogen, divinyl, vinylbenzene is the synthetic terpolymer of monomer, can embody three kinds of synergisticing performances between the component, has high impact, high heat-resisting, resistance to chemical attack, electrical insulation capability is good, dimensional stability is excellent, molding shrinkage is little, the excellent specific properties such as processing characteristics is good, and prepared product appearance glossiness is good, can electroplate, the secondary processing such as spraying, be widely used in electronics, automotive industry, household electrical appliance, office equipment, electric product, the fields such as Communication Equipment are that a kind of consumption is large, broad-spectrum engineering plastics; Wherein, the ABS material of extrusion grade is mainly used in the fields such as household electrical appliances, automobile, and all there is the extrusion-grade ABS trade mark of oneself in each company, and the most general is strange beautiful 749SK and D120 of Taiwan.
Yet ABS extrusion board impact property at low temperatures is lower, can not satisfy client's requirement, as: strange beautiful D120 extrusion board is under the environment of 40 degrees below zero, and horizontal notched Izod impact strength is 12KJ/m
2, notched Izod impact strength is 16KJ/m longitudinally
2, so just cause this material can not be used for the automotive field of having relatively high expectations.The horizontal low temperature notched shock strength that automotive field requires to extrude ABS sheet material is not less than 16KJ/m
2, vertically the low temperature notched shock strength is not less than 20KJ/m
2, existing material can't reach high like this performance requriements, thereby has limited its further application.For improving the shock strength of material, generally realize by in material prescription, increasing toughner, common toughner is high glue powder or MBS, but the adding of high glue powder or MBS can not significantly improve the low-temperature impact-resistant intensity of alloy material, and prepared material can't reach above-mentioned requirements.The low temperature impact properties that how to increase ABS sheet material has been the primary study direction of each material producer.
Summary of the invention
The technical problem to be solved in the present invention is: a kind of low-temperature impact-resistant extrusion-grade ABS alloy material is provided, and the horizontal and vertical low temperature notched shock strength of the extrusion board of this alloy material is higher than respectively 16KJ/m
