Abstract
The invention discloses a kind of low smell PC/ABS alloy material and preparation method thereof.Described low smell PC/ABS alloy material, comprises the component of following weight parts: ABS resin 50 parts, PC resin 40-60 part, tetrafluoroethylene 0.5-1.5 part, chemical deodovization agent 1-2 part.Each raw material is taken by proportioning, after mixing, melting mixing, extruding pelletization.Low smell PC/ABS alloy material of the present invention, has lower smell, meets automotive upholstery test smell PV3900 standard, is particularly suitable for being injection molded into various automotive upholstery.
Description
Technical field
The present invention relates to a kind of plastic material and preparation method thereof, particularly relate to a kind of low smell PC/ABS alloy material and preparation method thereof.
Background technology
PC/ABS alloy, it is the mixture of polycarbonate and acrylonitrile-butadiene-styrene copolymer, it is the thermoplastic plastic rubber by polycarbonate and acrylonitrile-butadiene-styrene copolymer ABS, combine the excellent specific property of bi-material, the formability of ABS material and the mechanicalness of PC, shock strength and the character such as heatproof, uvioresistant UV, can be widely used on automotive interior parts, business machine, the communication apparatus, electrical home appliances and set lights.Typically used scope is phone housing, computer and business machine housing, electrical equipment, lawn horticultural machine, auto parts dashboard, inside fitting and wheel cover.
Along with the lifting of life idea, the requirement of people to automobile is also more and more higher.Macromolecular material and polymer composite are as the main raw of automotive upholstery, and its smell height has larger impact to smell in car.If smell is larger in car, not only have a strong impact on reading with car body of human consumer, also have adverse influence to the health of passenger, therefore, each main engine plants also pay attention to more to in-car air quality, propose higher odor property requirement to automotive material especially interior trim plastic material.
Summary of the invention
For above shortcomings in prior art, one of technical problem to be solved by this invention provides a kind of low smell PC/ABS alloy material.
Two of technical problem to be solved by this invention provides the preparation method of above-mentioned low smell PC/ABS alloy material.
Technical problem to be solved by this invention is achieved by the following technical solution:
A kind of low smell PC/ABS alloy material, comprises the component of following weight parts: ABS resin 50 parts, PC resin 40-60 part, tetrafluoroethylene 0.5-1.5 part, chemical deodovization agent 1-2 part.
Described chemical deodovization agent is (9Z, 12R)-ricinoleic acid zinc salt (2:1) and/or 3,5-di-t-butyl-4-hydroxycinnamic acid.
Preferably, described chemical deodovization agent, is made up of 40-60wt% (9Z, 12R)-ricinoleic acid zinc salt (2:1) and 40-60wt%3,5-di-t-butyl-4-hydroxycinnamic acid.
In the present invention, smell with the gas molecules generation chelatropic reaction being with peculiar smell, and then can be removed by chemical deodovization agent.
Present invention also offers the preparation method of above-mentioned low smell PC/ABS alloy material: take each raw material by proportioning, after mixing, melting mixing, extruding pelletization, namely obtain described low smell PC/ABS alloy material.
Concrete, each component can be mixed in high-speed mixer, control rotating speed at 300-400 rev/min, melting mixing, extruding pelletization in twin screw extruder, control barrel zone temperature at 240-260 DEG C, after extruding in the water of 10-40 DEG C cooling forming, namely obtain described low smell PC/ABS alloy material.
Obviously, in the present invention for improving other performances of product, other auxiliary agents can also be added adaptively, as antiaging agent, fire retardant, tinting material and static inhibitor etc.
Low smell PC/ABS alloy material of the present invention, has lower smell, meets automotive upholstery test smell PV3900 standard, is particularly suitable for being injection molded into various automotive upholstery.
