Abstract
The invention discloses a high-heat-resistance polypropylene material and a preparation method thereof. The high-heat-resistance polypropylene material comprises the following components in parts by weight: 30-80 parts of polypropylene, 5-10 parts of ethylene propylene diene monomer, 10-25 parts of talc powder, 5-10 parts of glass fiber and 0.2-0.8 part of thermal stabilizer. The method comprises the following steps of: weighing each raw material according to the proportion; uniformly mixing; melting and mixing; and extruding and granulating. The high-heat-resistance polypropylene material has higher heat resistance and high thermal stability, keeps high tensile strength, bending strength, bending modulus and impaction strength, and can be prepared into automobile interiors such as outer side plates of driving seats, small covers, inner plates of side plates, plastic sheets of inner side plates, outer side plates of passenger seats, door plate handrail frameworks, door embedded plaque frameworks, and door embedded plaques.
Description
Technical field
The present invention relates to a kind of plastic material and preparation method thereof, relate in particular to a kind of high heat resistance polypropylene material and preparation method thereof.
Background technology
Polypropylene, english abbreviation is PP, is nineteen fifty-seven at first to drop into industrial production in Italy, is another the important plastics variety after polyethylene (PE).It has thermotolerance preferably, can be not destroyed at 135 ℃ of boiling 1000h yet, and the specific heat capacity of PP, thermal conductivity all are 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, the 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 the effect.PP at room temperature is insoluble to any solvent, but can be at some solvent, and as swelling in tetracol phenixin, trichloromethane, dithiocarbonic anhydride, benzene, when temperature raises, PP is dissolvable in water in some solvent.PP is more responsive to the effect of oxygen, particularly when temperature is higher.Its ultraviolet-resistant capacity is very poor, also is subject to the destruction of high-energy radiation, when being subject to above-mentioned destruction, and its generation lower-molecular substance of all can degrading.The existence of copper can sharply strengthen the oxidative degradation speed of PP, makes its very fast embrittlement, therefore be referred to as " copper evil ".PP has more outstanding stress cracking resistance.But its winter hardiness is poor, weathering resistance is also bad, and high temperature is the rigidity deficiency.
In current technology, because some performance of PP is not ideal enough, particularly resistance toheat is not good.
Summary of the invention
For above shortcomings in prior art, one of technical problem to be solved by this invention provides a kind of high heat resistance polypropylene material, has good resistance toheat.
Two of technical problem to be solved by this invention provides the preparation method of above-mentioned high heat resistance polypropylene material.
The present invention seeks to be achieved through the following technical solutions:
A kind of high heat resistance polypropylene material, comprise the component of following weight parts: polypropylene 30-80 part, terpolymer EP rubber 5-10 part, talcum powder 10-25 part, glass fibre 5-10 part, thermo-stabilizer 0.2-0.8 part.
Described polypropylene is Co-polypropylene.
Described thermo-stabilizer consists of by weight following component: butyl maleate dibutyl tin 10-30 part, Zinic stearas 20-40 part, 2-phenylindone 20-40 part.
Described high heat resistance polypropylene material also comprises: barium sulfate 1-3 part.
The present invention also provides the preparation method of above-mentioned high heat resistance polypropylene material: take each raw material by proportioning, after mixing, melting mixing, extruding pelletization, obtain described high heat resistance polypropylene material.
Mixed processes can carry out in general mixing machine, controls rotating speed at 300-400 rev/min, and melting mixing, extruding pelletization operation can be carried out in general screw extrusion press, controls barrel zone temperature at 200-220 ℃.
Obviously, for improving other performances of product, can also add adaptively other auxiliary agents, as photostabilizer, fire retardant, tinting material and static inhibitor etc. in the present invention.
Concrete, in the present invention:
Terpolymer EP rubber, english abbreviation is EPDM, is the terpolymer of ethene, propylene and non-conjugated diene hydrocarbon, 1963 start to commercially produce.The topmost characteristic of EPDM is exactly its superior resistance to oxidation, anti-ozone and erosion-resistant ability.Because terpolymer EP rubber belongs to polyolefine family, it has fabulous vulcanization characteristics.In the middle of all rubber, EPDM has minimum proportion.It can absorb a large amount of fillers and oil and influencing characteristic is little.Therefore can the cheap rubber compound of cost of manufacture.
The butyl maleate dibutyl tin, English name: di-n-butyltin monobutyl maleate, another name: two (butyl maleate) dibutyl tin; Dl-n-butyltin di (monobutyl maleate), No. CAS: 66010-36-4.
Zinic stearas, another name: stearic acid zinc salt, English name: Zinc stearate, English another name: Stearic acid zinc salt, No. CAS: 557-05-1.
2-phenylindone, english name: 2-Phenylindole, No. CAS: 948-65-2.
Barium sulfate, English another name: Barium sulfate, Artificial heavy spar, Blanc fixe, Barium sulfate precipitated, Synthetic barytes, Terraponderosa, Permanent white, No. CAS: 7727-43-7.Be preferably in the present invention process white, preferably adopt nano level.Barium sulfate can increase the performances such as hardness, intensity, the raising of goods be heat-resisting and wear-resisting, is the tool functional filler of development prospect, and particularly composite with thermo-stabilizer butyl maleate dibutyl tin, Zinic stearas and 2-phenylindone, performance is better.
Polypropylene and terpolymer EP rubber blend can improve its toughness and winter hardiness, have anti-ozone, anti-oxidant and corrosion resistance preferably, also have certain shockproof effect simultaneously, after adding talcum powder in formula, can reduce frictional coefficient, improve self lubricity.In the basic components of polypropylene, terpolymer EP rubber, talcum powder and glass fibre, add the thermal stability that thermo-stabilizer can improving product, the optimum ratio of butyl maleate dibutyl tin, Zinic stearas and 2-phenylindone, after further composite with barium sulfate, make product there is higher heat resisting temperature, good thermal stability, draw high intensity, flexural strength, modulus in flexure and shock strength all more excellent.
High heat resistance polypropylene material of the present invention, have higher thermal stability, resistance toheat, can be processed into easily the part of different shape by Shooting Technique, can be used for making automotive sealant, various operation handle arm and handle etc.
Concrete, can for the production of automotive upholstery as follows: the outer side plate of driver's seat, little cover cap, side plate inner panel, interior side plate plastic, the outer side plate of passenger seat, door panel arm rest skeleton, door decorative panel skeleton, door decorative panel.
