Modified polypropylene plastic

Abstract

The invention discloses a modified polypropylene plastic, which comprises the following raw materials in parts by weight: 80-150 parts of PP, 3-12 parts of POE, 1-9 parts of grafted EVA, 1-5 parts ofa mixture of silicone powder and PE wax, 5-30 parts of calcium carbonate and 2-15 parts of a flame retardant. The modified polypropylene plastic is prepared by adding the silicone powder, so that themechanical property of the polypropylene plastic is improved, and the toughness of the polypropylene plastic is improved; the silicone powder and the PE wax are compounded to achieve a synergistic effect, so that the mechanical property of the polypropylene plastic is further improved.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to modified polypropylene plastics. Background technique [0002] Polypropylene PP is a thermoplastic synthetic resin with excellent performance, which is a colorless and translucent thermoplastic lightweight general-purpose plastic. With chemical resistance, heat resistance, electrical insulation, high-strength mechanical properties and good high wear-resistant processing properties, etc., it has been widely used in many fields such as machinery, automobiles, electronic appliances, construction, textiles, packaging, agriculture, forestry, fishery and food industry. Extensive development and application. [0003] However, polypropylene also has many disadvantages which affect its series of engineering applications. The molding shrinkage of polypropylene is too large, it is easy to be brittle at low temperature, the toughness is insufficient, and the wear resi...

Problems solved by technology

[0003] However, polypropylene also has many shortcomings, which affect its series of engineering applications.

The molding shrinkage of polypropylene is too large, it is easy to be brittle at low temperature, the toughness is insufficient, and the wear resistance is too low, which greatly limits the development of polypropylene. Therefore, polypropylene must be modified

[0004] Existing technology "EVA / POE / CaCO 3 / PP Blend Modification System Performance Research Han Wenxiang Rubber and Plastic Technology and Equipment, discloses a modified polypropylene plastic, by adding POE to graft EVA / CaCO 3 / PP composite system is modified, although it improves the toughness and low temperature brittleness of PP to a certain extent, but there are still deficiencies.
