Abstract

The invention discloses plastic masterbatch, and relates to the technical field of plastic masterbatch. The plastic masterbatch is prepared from the following raw materials in parts by weight: 70-80 parts of carrier resin, 8-14 parts of modified mica powder, 5-10 parts of modified nacrite, 1-5 parts of modified nano calcium carbonate, 2-6 parts of modified sepiolite fibers, 1-5 parts of lignin fibers, 1-3 parts of modified glass fibers, 1-3 parts of chlorinated polyethylene and 6-12 parts of chlorinated paraffin, wherein the length of the modified sepiolite fibers is 1-3 cm, the length of thelignin fibers is 0.2-0.6 cm, and the length of the modified glass fibers is 2-5 cm. The invention also provides a preparation method of the plastic masterbatch. The plastic masterbatch has the beneficial effects that the mechanical property of the plastic masterbatch is improved, the plastic masterbatch has good tensile strength, impact strength, bending strength, elongation at break and the like,meanwhile, the glossiness of the surface of a plastic product can be improved, the effects of shielding ultraviolet rays and resisting bacteria are achieved, the plastic product is prevented from being aged, and the service lifetime of the plastic product is prolonged.

Description

technical field [0001] The invention relates to the technical field of plastic master batches, in particular to a plastic master batch and a preparation method thereof. Background technique [0002] Plastic products are a general term for household and industrial products processed from plastic as the main raw material. Including plastic as raw material for injection molding, blister and other products of all processes. Together with synthetic rubber and synthetic fibers, it forms the three major synthetic materials indispensable to daily life. Specifically, plastic is a material with natural or synthetic resin as the main component, adding various additives, which can be molded into a certain shape under certain conditions such as temperature and pressure, and maintains the same shape at room temperature. Compared with metal, stone, and wood, plastic products have the advantages of low cost and strong plasticity, and are widely used in the national economy. The plastics i...
