Abstract
The invention discloses a kind of Low-odor polypropylene material and preparation method thereof.Described Low-odor polypropylene 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.Take each raw material by proportioning, after mixing, melting mixing, extruding pelletization, can obtain.Low-odor polypropylene material of the present invention, has lower smell, meets automotive upholstery test smell PV3900 standard.
Description
Technical field
The present invention relates to a kind of plastic material and preparation method thereof, particularly relate 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, also can not be destroyed at 135 DEG C of boiling 1000h, and specific heat capacity, the thermal conductivity of PP 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 allowed, 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 to it, other reagent to it all without acting on.
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-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 kind of Low-odor polypropylene 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, 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-odor polypropylene material: take each raw material by proportioning, after mixing, melting mixing, extruding pelletization, namely 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 DEG C, the polypropylene material extruded cooling forming in the cold water of 10-40 DEG C, namely obtains described Low-odor polypropylene 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.
Polypropylene and terpolymer EP rubber is blended can improve its toughness and winter hardiness, has good ozone-resistant, anti-oxidant and corrosion resistance, also has certain shockproof effect simultaneously, after adding talcum powder, can reduce frictional coefficient in formula, improve self lubricity.In polypropylene, terpolymer EP rubber and talcous basic components, adding chemical deodovization agent can with the gas molecules generation chelatropic reaction being with peculiar smell, and then smell is removed, the present invention is made to have lower smell, meet automotive upholstery test smell PV3900 standard, draw high intensity, flexural strength, modulus in flexure and shock strength simultaneously and all comparatively meet the demands.
Low-odor polypropylene material of the present invention, can be processed into the part of different shape easily, can be used for making automotive upholstery by Shooting Technique.
