Abstract

The invention belongs to the field of plastics, and especially relates to a high-strength composite plastic. The composite plastic comprises, by mass, 120-160 parts of polyethylene, 10-20 parts of glass fibers, 10-20 parts of carbon fibers, 10-20 parts of silica, 1-10 parts of a toughening agent, 1-3 parts of stearic acid, 20-30 parts of polyethylene glycol, 1-5 parts of polyvinyl alcohol fibers, 5-10 parts of styrene-butadiene rubber, 5-10 parts of a pigment and filler, 1-5 parts of a coupling agent, 1-5 parts of a dispersant, 1-5 parts of a stabilizer, 1-5 parts of a plasticizer and 1-5 parts of an antioxidant. A preparation method of the composite plastic is characterized in that all above materials are mixed, and then are granulated by a granulator. The plastic prepared by the above formula of the invention has a very high strength, greatly improved impact resistance and greatly improved tensile strength, and can be widely applied to plastic products in various fields.

Description

technical field [0001] The invention belongs to the field of plastics, in particular to a high-strength composite plastic and a preparation method thereof. Background technique [0002] As plastic products are more and more widely used in daily production and life, people have higher and higher performance requirements for plastic products. Compared with other materials, plastic products have the advantages of lightness, good corrosion resistance, and low price. In some special environments, plastic products are required to have higher strength. The strength of plastic products includes impact resistance and tensile capacity, but the application of unmodified plastic products is limited due to their low strength. Therefore, it is necessary to improve the existing technology and develop a new type of high-strength plastic. Contents of the invention [0003] Aiming at the above technical problems, the present invention provides a high-strength composite plastic and a prepa...
