Abstract

The invention discloses a low-odor ABS (acrylonitrile butadiene styrene)/PVC (polyvinyl chloride)/PETG (polyethylene terephthalate glycol) alloy material and a preparation method thereof. The low-odor ABS/PVC/PETG alloy material comprises the following components in parts by weight: 30-80 parts of ABS resins, 40-60 parts of PVC resins, 10-20 parts of PETG resins, 1-5 parts of compatibilizer and 1-2 parts of chemical deodorants. The preparation method is characterized by comprising the following steps of weighing the raw materials according to the ratio, mixing the raw materials uniformly and then carrying out melting, mixing, extruding and granulating. The low-odor ABS/PVC/PETG alloy material has lower odor, conforms to the automotive interior trim odor test standard PV3900, can be used in injection molding to easily machine various shapes of parts and is especially suitable for injection molding of various automotive interior trims.

Description

A kind of low smell ABS/PVC/PETG alloy material and preparation method thereof

Technical field

The present invention relates to a kind of plastic material and preparation method thereof, relate in particular to a kind of low smell ABS/PVC/PETG alloy material and preparation method thereof.

Background technology

ABS/PVC/PETG alloy, has good thermal characteristics, processing fluidity and mechanical property, and surface gloss, tint permanence are also better.Combine the excellent specific property of three kinds of materials, 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.

ABS resin (acrylonitrile-butadiene-styrene copolymer, ABS is the acronym of Acrylonitrile Butadiene Styrene) is that a kind of intensity is high, good toughness, be easy to thermoplastics type's Polymer Materials ' Structure of machine-shaping.

Polyvinyl chloride resin, claims again polyvinyl chloride (PVC) RESINS, synthetic by radical polymerization by vinylchlorid.English name: PolyvinylChloride.Polyvinyl chloride resin is one of important organic synthesis material, is widely used in the fields such as industry, building, agricultural, daily life, packing, electric power, public utilities.

PETG is a kind of transparent plastics, is a kind of non-crystalline type copolyesters, and the comonomer that PETG is conventional is 1,4 cyclohexane dimethanol (CHDM), and full name is polyethylene terephthalate-1,4 cyclohexane dimethanol ester.PETG has outstanding toughness and high impact strength, and its resistance to impact shock is 3～10 times of modified polyacrylate class, and has very wide work range, and high physical strength and excellent flexibility are high compared with PVC transparency, good luster.

Along with the lifting of life idea, people are also more and more higher to the requirement of automobile.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 passenger's health is had to adverse influence, therefore, each main engine plants also pay attention to more to in-car air quality, and automotive material especially interior trim has been proposed to higher odor property requirement with 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 ABS/PVC/PETG alloy material.

Two of technical problem to be solved by this invention provides the preparation method of above-mentioned low smell ABS/PVC/PETG alloy material.

Technical problem to be solved by this invention is achieved by the following technical solution:

A smell ABS/PVC/PETG alloy material, comprises the component of following weight parts: ABS resin 30-80 part, polyvinyl chloride resin 40-60 part, PETG resin 10-20 part, expanding material 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, by 50-80wt% (9Z, 12R)-ricinoleic acid zinc salt (2:1) and 20-50wt%3,5-di-t-butyl-4-hydroxycinnamic acid forms.

Described expanding material is a kind of or its mixture in chlorinatedpolyethylene (being called for short CPE) and styrene-maleic anhydride copolymer (being called for short S-MA multipolymer).

In the present invention chemical deodovization agent can with the gas molecules generation chelatropic reaction with peculiar smell, and then smell is removed.

The present invention also provides the preparation method of above-mentioned low smell ABS/PVC/PETG alloy material: by proportioning, take each raw material, after mixing, melting mixing, extruding pelletization, obtain described low smell ABS/PVC/PETG 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 160-180 ℃, after extruding in the water of 10-40 ℃ cooling forming, obtain described low smell ABS/PVC/PETG alloy material.

Obviously, for improving other performances of product, can also add adaptively other auxiliary agents, as antiaging agent, fire retardant, tinting material and static inhibitor etc. in the present invention.

Low smell ABS/PVC/PETG alloy material of the present invention, there is lower smell, meet automotive upholstery test smell PV3900 standard, can be processed into easily by Shooting Technique the part of different shape, can be used for making in automobile and car outer enclosure, the widgets such as bearing circle, oil guide pipe and handle and button, car outside comprises front radiator grill and lampshade etc.
