Description

A kind of metallize effect ABS that exempts from is material modified and preparation method thereof

Technical field

It is material modified and preparation method thereof to the present invention relates to a kind of metallize effect ABS that exempts from, and belongs to polymeric material field.

Background technology

Acrylonitrile-butadiene-styrene terpolymer (ABS) resin is one of five big synthetic resins; Its shock resistance, thermotolerance, lower temperature resistance, chemical proofing and excellent electrical properties; Also have characteristics such as the processing of being prone to, product size is stable, surface luster property is good; Application, painted easily; Can also carry out surperficial spraymetal, plating, welding, hot pressing and secondary processing such as bonding, be widely used in industrial circles such as machinery, automobile, electronic apparatus, instrument, weaving and building.Transparency ABS resin comprises two types of TEB 3K-acrylonitrile-butadiene-styrene (ABS) tetrapolymer (MABS) and TEB 3Ks-butadiene-styrene terpolymer (MBS); MABS is succeeded in developing in 1962 by Japan SYnthetic Rubber Co. Ltd, and Japanese TORAY, German BASF, U.S. DOW chemistry have successively been developed ABS.The MBS resin is at first developed by Rohm & Haas company, the MBS of exploitation such as Mitsubishi Zantrel company subsequently.MABS and MBS resin transmittance reach more than 85%, and MABS shock strength, low temperature resistant owing to MBS is widely used in the product of transparent requirement.

For improving the plastic part outward appearance, prolonging the product life-span, need usually product is carried out spray treatment.The spraying coating process flow process comprises: annealing or whole processing, oil removing, remove electricity, dedusting, spray, stay operation such as flat, oven dry.There is following shortcoming in spraying coating process: 1 cost is high, and Production Flow Chart is long, efficient is low, good article rate is low, equipment or factory building investment are big; 2 non-environmental protection, the spraying contaminate environment, to operator's health cause damage, security risk is big; 3 difficulties recycle, and defective products is difficult to recycle.

In sum, be necessary that development environment is friendly, to can be recycled, exempt from cheaply metallize effect ABS material modified, in fields such as household appliances, IT, automobiles development potentiality preferably arranged, market outlook are very wide.

Summary of the invention

The objective of the invention is to develop a kind of environmental protection, to exempt to spray, have the ABS of metalluster material modified and preparation method thereof.

In order to achieve the above object, it is material modified to the invention provides a kind of metallize effect ABS that exempts from, it is characterized in that, by forming in the raw material of weight part as follows:
