Abstract

The invention discloses a low-odor polypropylene material and a preparation method thereof. The low-odor polypropylene material comprises the following components in parts by weight: 30 to 80 parts of co-polypropylene, 5 to 20 arts of ethylene-propylene-diene monomer, 10 to 30 parts of talcum powder, and 1 to 2 parts of a chemical deodorant. The preparation method comprises the following steps of weighing each raw material based on proportion; uniformly mixing; melting and mixing; and extruding and granulating to obtain the low-odor polypropylene material. The low-odor polypropylene material has a relatively low odor and meets the PV3900 standard on testing of the odor of internal ornaments of a car.

Description

A kind of low odor polypropylene 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 odor polypropylene material and preparation method thereof.
Background technology
Polypropylene, english abbreviation is PP, is nineteen fifty-seven first to drop into industrial production in Italy, is another the important plastics variety after polyethylene (PE).It has good thermotolerance, can be not destroyed at 135 ℃ of boiling 1000h yet, and the specific heat capacity of PP, thermal conductivity are all less than PE, but heat insulating ability is better than PE.PP belongs to non-polar polymer, has excellent dielectricity and electrical insulating property, and electrical property is not subject to the impact of ambient moisture and electric field frequency substantially, and in the working range allowing, temperature rising can make electrical property reduce, and its arc resistance is higher.The chemical resistant properties of PP is good, except strong oxidizer has erosion action it, other reagent to it all without effect.
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 odor polypropylene material.
Two of technical problem to be solved by this invention provides the preparation method of above-mentioned low odor polypropylene material.
Technical problem to be solved by this invention is achieved by the following technical solution:
A material, comprises the component of following weight parts: Co-polypropylene 30-80 part, terpolymer EP rubber 5-20 part, talcum powder 10-30 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 40-60wt% (9Z, 12R)-ricinoleic acid zinc salt (2:1) and 40-60wt%3,5-di-t-butyl-4-hydroxycinnamic acid forms.
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 odor polypropylene material: by proportioning, take each raw material, after mixing, melting mixing, extruding pelletization, obtain described low odor polypropylene 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 200-220 ℃, the polypropylene material of extruding cooling forming in the cold water of 10-40 ℃, obtains described low odor polypropylene 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.
Polypropylene and terpolymer EP rubber blend can improve its toughness and winter hardiness, have good anti-ozone, anti-oxidant and corrosion resistance, also have certain shockproof effect simultaneously, add after talcum powder in formula, can reduce frictional coefficient, improve self lubricity.In polypropylene, terpolymer EP rubber and talcous basic components, add chemical deodovization agent can with the gas molecules generation chelatropic reaction with peculiar smell, and then smell is removed, make the present invention there is lower smell, meet automotive upholstery test smell PV3900 standard, draw high intensity, flexural strength, modulus in flexure and shock strength simultaneously and all meet the demands.
Low odor polypropylene material of the present invention, can be processed into the part of different shape easily by Shooting Technique, can be used for making automotive upholstery.
