Abstract
The invention provides a toughening wear-resistance acrylonitrile-butadiene-styrene (ABS)/polymethyl methacrylate (PMMA) alloy material and a preparation method thereof. By using a methyl methacrylate-butadiene-styrol copolymer (MBS) and a styrene-acrylonitrile copolymer (SAN) for increasing toughness of ABS and PMMA, a wear resistant modifier and a scratch resistant agent are used for increasing the wear resistance of the alloy, and finally, ABS, PMMA, SAN and relative auxiliary agents enable blending extrusion by a double screw extruder, and the modified toughening wear-resistance ABS/PMMA alloy material can be obtained after steps of traction, cooling and granulation are carried out. The modified toughening wear-resistance ABS/PMMA alloy material has more excellent toughness and wear resistance than that of a traditional ABS/PMMA alloy material.
Description
Technical field
The present invention relates to high molecule alloy material field, be specifically related to a kind of toughened antiwear alloy material and preparation method, be mainly used in automobile and household appliance technical field.
Background technology
ABS is the engineering plastics of high comprehensive performance, there is excellent impact resistance, good low-temperature performance and chemical proofing, high abrasion resistance, good stability of the dimension, surface luster property is good, easy application and painted etc., but there are some defects in ABS, as high in melt viscosity, poor fluidity, thermostability and weathering resistance are not good.PMMA is a kind of good in optical property, has excellent weather resistance, and physical strength is good, has high transparency, and transmissivity is up to 91%-93%, but the shock strength of PMMA is not high, especially to notch sensitive.ABS and PMMA is carried out melt blending, the ABS/PMMA alloy of preparation can the advantage of comprehensive two kinds of plastics, make up respective shortcoming, the invention solves fragility and the wear resistance problem of ABS/PMMA alloy material, acquisition has toughened antiwear alloy material, and makes material have good mechanical property.
Summary of the invention
The invention provides a kind of toughened antiwear ABS/PMMA alloy material and preparation method, goods prepared by this material, for automobile and household appliance shell, utilize the auxiliary agent such as toughner, SAN, scratch resistance liniment, abrasion resistance modifier to improve toughness and the wear resistance of alloy material.This alloy material has good mechanical property, reduces production cost again.
