Description

A kind of polypropylene composite material of high impact-resistant

Technical field

The present invention relates to a kind of polypropylene composite material of high impact-resistant.

Background technology

Polyacrylic degree of crystallinity is high, compound with regular structure, thus has excellent mechanical property, and the absolute value of Mechanical Properties of PP is higher than polyethylene.Polypropylene has higher tensile strength, but with the raising of isotactic index, the shock strength of material declines to some extent.PP be used for automotive industry there is stronger competitive power, but because of its modulus and thermotolerance lower, shock strength is poor, therefore can not directly be used as auto parts machinery, use polypropylene composite material improve performance, enhancing shock resistance.Polypropylene (PP) is a kind of general-purpose plastics of high comprehensive performance, can obtain high strength, high tenacity PP matrix material by composite.This kind of matrix material is widely used in the fields such as automobile, household electrical appliances, packaging.At automotive field, high-impact PP matrix material has become the main flow of automobile bumper material.In PP blending and modifying, toughening modifying is one of main research direction, both at home and abroad the research report of existing many this respects, and the high-impact PP developed is widely used as material dedicated for bumper.But Polypropylene For Low-temperature Resistance impact is poor in the market, and especially low-temperature impact resistance is more bad, and creep resistant is poor, more aging, make it apply and be limited by very large, require further improvement.

Summary of the invention

For the deficiencies in the prior art, the problem to be solved in the present invention is, provides a kind of polypropylene composite material of high impact-resistant, and shock strength is high, good fluidity, adds the rigidity of matrix material, thermotolerance, and not easily aging, preparation method is simple.

For solving prior art problem, technical scheme provided by the invention is, a kind of polypropylene composite material of high impact-resistant, and it is made up of the raw material of following parts by weight:

Polypropylene 40-60 part, nano-calcium carbonate 14-22 part, compatilizer 2-4 part, fire retardant 2-5 part, ammonium tetramolybdate 12-17 part, maleic anhydride 2-4 part, glass fibre 20-35 part, polycarbonate 6-9 part, palmitinic acid magnesium soap 2-4 part, silicon-dioxide 8-14 part, copper powder 3-5 part, silicone resin 4-7 part, ABS7-12 part, small molecule chain extender 10-16 part, oligomer polyol 12-18 part.

The invention has the beneficial effects as follows: the polypropylene composite material of high impact-resistant of the present invention, shock strength be high, good fluidity, add the rigidity of matrix material, thermotolerance, not easily aging, preparation method is simple.
