Abstract
The invention discloses a scratch-resistant polypropylene compound with a self-restoring function and a preparation method thereof. The polypropylene compound comprises the following components by weight percent: 28% to 91.8% of polypropylene, 0.1% to 1% of heat stabilizer, 0.1% to 1% of lubricant, 2% to 20% of flexibilizer, 1% to 10% of scratch restoring agent and 5% to 40% of inorganic mineral powder. According to the polypropylene compound, after scratches are caused by the force of 4N, the DL (5 minutes) is less than or equal to 1.5, the DL (10 minutes) is less than or equal to 0.5, and the DL (30 minutes) is less than or equal to 0.0.5. If the surface of the polypropylene compound is scratched slightly, after the polypropylene compound is exposed in the natural light for 10 to 30 minutes, the scratches can be restored automatically in a normal-temperature status. Therefore, the polypropylene compound disclosed by the invention can be applied to situations with high requirements to the scratch resistance such as automotive interior decoration, household appliance casings and the like.
Description
Technical field
The present invention relates to a kind of damage resistant polypropylene composite with self-regeneration function and preparation method thereof, be specifically related to the requirement of effects on surface damage resistant higher automotive trim or household appliances shell polypropylene composite and preparation method thereof.
Background technology
Automotive interior material or home electric appliance material in use inevitably can produce slight scuffing or cut, damage for the outward appearance of product, thereby affect human consumer's use mood.The automotive trim polypropylene composite generally adopts mineral fillers such as adding talcum powder to increase rigidity and the thermotolerance of material at present, add simultaneously rubber and improve toughness and the lower temperature resistance of material, but mineral filler or rubber add that all can to make material be subject to slightly scratching the rear surface cut more obvious.
For reducing this cut effect that visually produces, the damage resistant polypropylene composite generally adopts damage resistant auxiliary agents such as adding amides and silicone at present, the principle of this raising damage resistant is that the damage resistant auxiliary agent forms a kind of upper layer at material surface, improve the smooth degree of material surface, thereby the brightness flop at material cut place is not obvious after standing slight the scuffing.But the defective of this damage resistant modification technology is, can not eliminate the physics cut after adding the damage resistant auxiliary agent, and the physics cut can be more obvious, and just optical effect is not obvious.
