Abstract
The invention discloses basalt fiber enhanced polypropylene composite plastic for automobile interior parts. The composite plastic consists of the following components in parts by weight: 100 parts of homo-polypropylene, 10-20 parts of basalt fiber, 5-7 parts of a compatilizer and 0.8-1.2 parts of a coupling agent. The basalt fiber enhanced polypropylene composite plastic for automobile interior parts is excellent in chemical resistance, obvious in acid-alkali resistance, and enhanced in bending modulus, tensile strength and notch impact strength.
Description
Technical field
The present invention relates to a kind of plastics, particularly relate to a kind of automotive upholstery basalt fibre Reinforced Polypropylene composite plastic.
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.PP is at room temperature insoluble to any solvent, but can at some solvent, and as swelling in tetracol phenixin, trichloromethane, dithiocarbonic anhydride, benzene, when temperature raises, PP is dissolvable in water in some solvent.The effect of PP to oxygen is more responsive, particularly when temperature is higher.Its ultraviolet-resistant capacity is very poor, is also subject to the destruction of high-energy radiation, and when being subject to above-mentioned destruction, it all can be degraded generation lower-molecular substance.The existence of copper sharply can strengthen the rates of oxidative degradation of PP, makes it very fast brittle, therefore is referred to as " copper evil ".PP has comparatively outstanding stress cracking resistance.But its winter hardiness is poor, weathering resistance is also bad, and high temperature then rigidity is not enough.
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 basalt fibre Reinforced Polypropylene composite plastic.
Technical problem to be solved by this invention, is achieved by the following technical solution:
A kind of automotive upholstery basalt fibre Reinforced Polypropylene composite plastic, is made up of following component: homo-polypropylene 100 parts, basalt fibre 10-20 part, compatilizer 5-7 part, coupling agent 0.8-1.2 part by weight.
Described compatilizer is PP-g-MAH compatilizer, Chinese name: polypropylene grafted maleic anhydride.
Described coupling agent, is made up of by weight following component: two (dioctyl phosphite base) titanium isopropylate 40-60 parts and trimethoxy [2-(7-oxabicyclo [4.1.0]-3-in heptan base) ethyl] silane 40-60 part.Two (dioctyl phosphite base) titanium isopropylates and trimethoxy [2-(7-oxabicyclo [4.1.0]-3-in heptan base) ethyl] silane are uniformly mixed obtained described coupling agent.
Two (dioctyl phosphite base) titanium isopropylate, is called for short coupling agent KR-41B.
Trimethoxy [2-(7-oxabicyclo [4.1.0]-3-in heptan base) ethyl] silane, No. CAS: 3388-04-3.
Basalt fibre, be basalt building stones after 1450 DEG C of-1500 DEG C of meltings, by the continuous fibre of 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, can directly proceed in ecotope after product abandonment, without any harm, because of but a kind of genuine green, environment-friendly materials.China is classified as basalt fibre as one of four large fibers that China gives priority to, substantially achieves 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.
Adopt industry universal method that coupling agent and basalt fibre are mixed to get treated basalt fiber.Such as, coupling agent ethanol, Virahol, white oil or dimethylbenzene equal solvent are diluted, then evenly spreads in basalt fibre, by baking oven, solvent is volatilized completely, again the basalt fibre pulverizer after oven dry is ground into fine powder, obtains treated basalt fiber.
Again treated basalt fiber is mixed with homo-polypropylene, compatilizer, extruding pelletization, described automotive upholstery basalt fibre Reinforced Polypropylene composite plastic can be obtained.
Automotive upholstery basalt fibre Reinforced Polypropylene composite plastic of the present invention has excellent chemical resistant properties, acidproof, alkali resistance remarkable, and modulus in flexure, tensile strength and notched Izod impact strength are enhanced.
