Abstract
The invention discloses a polypropylene composite material. The polypropylene composite material is prepared from, by weight, 50-65 parts of co-polypropylene, 15-25 parts of calcium carbonate, 5-15 parts of polyolefin elastomer, 3-8 parts of lubricating agent, 1-5 parts of titanate coupling agent and 0.2-0.5 part of antioxygen. According to the polypropylene composite material, the compatibility of the calcium carbonate and the polypropylene is effectively improved, and the bending and tensile strength of the composite material is improved; meanwhile, the impact strength and elongation of the composite material are lowered, and the dimensional stability is improved.
Description
Technical field
The present invention relates to field of compound material, particularly relate to a kind of polypropylene composite material.
Background technology
Polypropylene is one of resins for universal use be most widely used, because its abundant raw material, simple process, price are excellent honest and clean, compared with other plastics, there is good over-all properties, add that its goods are nonpoisonous and tasteless, glossiness is good, is widely used in the fields such as electrical equipment, automobile, packaging and daily necessities.But Polypropylene cold-resistant is poor, fragile under low temperature disconnected, product size poor stability, therefore, makes polypropylene material through engineering approaches by modification, is the focus in domestic and international modifying plastics and applied research always.
Summary of the invention
The object of the invention is to the above problem overcoming prior art existence, a kind of polypropylene composite material is provided, meets the primary demand in market.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the present invention is achieved through the following technical solutions:
A kind of polypropylene composite material, counts by weight, comprises the Co-polypropylene of 50 ~ 65 parts, the calcium carbonate of 15 ~ 25 parts, the polyolefin elastomer of 5 ~ 15 parts, the lubricant of 3 ~ 8 parts, the titanate coupling agent of 1 ~ 5 part, the oxidation inhibitor of 0.2 ~ 0.5 part.
Further, the fineness of described calcium carbonate is 1250 orders.
Further, also Calcium of intensifiens is comprised in described matrix material.
Further, TAS-2 bright lubricant selected by described lubricant.
Further, described oxidation inhibitor comprises thio-2 acid dibasic acid esters and Hinered phenols antioxidant.
Further, described polyolefin elastomer is mechanical blending type and is uneven two phase structure.
The invention has the beneficial effects as follows:
Material of the present invention effectively improves calcium carbonate and polyacrylic consistency, improves the bending of matrix material and tensile strength, also reduces shock strength and the elongation of matrix material simultaneously, improve dimensional stability.
Embodiment
Below in conjunction with embodiment, describe the present invention in detail.
A kind of polypropylene composite material, counts by weight, comprises the Co-polypropylene of 50 ~ 65 parts, the calcium carbonate of 15 ~ 25 parts, the polyolefin elastomer of 5 ~ 15 parts, the lubricant of 3 ~ 8 parts, the titanate coupling agent of 1 ~ 5 part, the oxidation inhibitor of 0.2 ~ 0.5 part.
Wherein, the fineness of calcium carbonate is 1250 orders.
Wherein, also Calcium of intensifiens is comprised in matrix material.
Wherein, TAS-2 bright lubricant selected by lubricant.
Wherein, oxidation inhibitor comprises thio-2 acid dibasic acid esters and Hinered phenols antioxidant.
Wherein, polyolefin elastomer is mechanical blending type and is uneven two phase structure.
More than show and describe ultimate principle of the present invention, principal character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and specification sheets just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.
