Abstract

The invention relates to a polyolefin reinforced material and preparation method thereof. The polyolefin reinforced material comprises the following components in parts by weight: 50-90 parts of polyolefin resin, 10-50 parts of inorganic reinforcement, 1-3 parts of fusion welding modifying agent, 0.1-2 parts of lubricating agent and 0-2 parts of other auxiliaries. Compared with the prior art, the polyolefin reinforced material has the advantages that the fusion welding mark strength during injection molding is improved by more than 85% on the basis of retaining the excellent mechanical property, and no appearance weld mark can be seen on the injection molding product.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a polyolefin reinforcing material and a preparation method thereof. Background technique [0002] Polyolefin materials are currently the most commonly used commercial polymer materials, and are widely used in automotive, electrical and other industries. Polyolefin resins are usually used more for polypropylene and polyethylene resins. After polyolefin resin is filled with inorganic substances such as talc, glass fiber, calcium carbonate, etc., it can significantly improve its rigidity and strength, and can greatly reduce costs. It is currently widely used. However, after being strengthened by inorganic substances, during the injection molding process, when several streams flow together in the mold flow channel, due to the difference in the fluidity of inorganic substances and the compatibility with polymers, the orientation of the molten materials at the in...
