Abstract
The invention discloses a basalt fiber-reinforced PP-HDPE composite plastic for automotive upholsteries. The composite plastic comprises the following components by weight: 100 parts of polypropylene, 20 to 30 parts of high density polyethylene, 10 to 20 parts of EPDM, 10 to 20 parts of a basalt fiber and 0.2 to 0.4 part of a coupling agent. The basalt fiber-reinforced PP-HDPE composite plastic provided by the invention has the advantages of excellent flexural modulus, tensile strength and notch impact strength and can be processed into automotive upholsteries of a variety of shapes through injection molding, i.e., inner cover plates of glove boxes, glove box buckets, auxiliary fascia console bodies, liners of storage boxes and panel storage boxes.
Description
Technical field
The present invention relates to a kind of plastics, relate in particular to a kind of automotive upholstery and strengthen PP and HDPE composite plastic with basalt fibre.
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 subjected 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 raise, PP was 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 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, need to improve toughness by modification, improve winter hardiness, weathering resistance, dyeability, further improve mechanical property and thermotolerance etc.
Summary of the invention
For above shortcomings in prior art, technical problem to be solved by this invention is to provide a kind of automotive upholstery and strengthens PP and HDPE composite plastic with basalt fibre.
Technical problem to be solved by this invention is achieved by the following technical solution:
A kind of automotive upholstery strengthens PP and HDPE composite plastic with basalt fibre, following component, consists of by weight: 100 parts of polypropylene, high density polyethylene(HDPE) 20-30 part, terpolymer EP rubber 10-20 part, basalt fibre 10-20 part, coupling agent 0.2-0.4 part.
Described polypropylene is Co-polypropylene.
Described coupling agent consists of by weight following component: two (dioctyl phosphite base) titanium isopropylate 40-60 parts and trimethoxy [2-(7-oxabicyclo [4.1.0] heptan-3-yl) ethyl] silane 40-60 part.Two (dioctyl phosphite base) titanium isopropylates and trimethoxy [2-(7-oxabicyclo [4.1.0] heptan-3-yl) ethyl] silane is uniformly mixed and makes described coupling agent.
Adopt industry universal method that coupling agent and basalt fibre are mixed to get to treated basalt fiber.For example, coupling agent, with ethanol, Virahol, white oil or the dilution of dimethylbenzene equal solvent, is then evenly spread in basalt fibre, by baking oven, solvent is volatilized fully, basalt fibre after drying again is ground into fine powder with pulverizer, obtains treated basalt fiber; Also can under the basalt fibre high-speed stirring, if controlled rotating speed 1500-3000r/min, spray into coupling agent, obtain treated basalt fiber.
Treated basalt fiber is mixed with polypropylene, high density polyethylene(HDPE), terpolymer EP rubber, extruding pelletization, can make described automotive upholstery and strengthen PP and HDPE composite plastic with basalt fibre again.
High density polyethylene(HDPE), High Density Polyethylene, referred to as HDPE, be high, the nonpolar thermoplastic resin of a kind of degree of crystallinity.The milky appearance of ortho states HDPE, be to a certain degree translucent in meagre cross section.
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.
Basalt fibre, be the basalt building stones after 1450 ℃ of-1500 ℃ of meltings, the continuous fibre formed by platinum rhodium bushing high speed pulling.Basalt continuous fiber is good stability not only, but also has electrical insulating property, anticorrosive, flame resistant, the multiple excellent properties such as high temperature resistant.In addition, the waste that the production technique of basalt fibre produces is few, and environmental pollution is little, after product abandonment, can directly proceed in ecotope, and without any harm, thereby be a kind of genuine green, environment-friendly materials.China has classified basalt fibre as one of four large fibers that China gives priority to, has basically realized suitability for industrialized production in China.Basalt continuous fiber is widely used in many aspects such as fibre reinforced composites, friction materials, shipbuilding materials, lagging material, automobile industry, high temperature filtration fabric and protection fields.
Two (dioctyl phosphite base) titanium isopropylate, be called for short coupling agent KR-41B.
Trimethoxy [2-(7-oxabicyclo [4.1.0] heptan-3-yl) ethyl] silane, No. CAS: 3388-04-3.
Automotive upholstery of the present invention strengthens PP with basalt fibre and the HDPE composite plastic has excellent modulus in flexure, tensile strength and notched Izod impact strength, can be processed into easily by Shooting Technique the automotive upholstery of different shape, as glove box inner cover plate, gloves hopper, accessory instrument panel body, parcel tray liner, panel parcel tray.
