Abstract

The invention belongs to the technical field of polypropylene particle preparation, particularly relates to a preparation process of recyclable coffee residue plant fiber polypropylene particles, and provides the following scheme aiming at the problems that an existing polypropylene particle preparation mode is complex, plant fiber preparation is not adopted, and the environmental protection performance is poor. The preparation method comprises the following preparation steps: S1, preparing raw materials, wherein the raw materials comprise 35-40 parts of coffee residue powder, 60-80 parts of a polypropylene resin, 2-5 parts of a compatilizer, 4-8 parts of a toughening agent component, 1-3 parts of a diffusant, 1-3 parts of maleic anhydride, 0.7-1.6 parts of an anti-uv agent, 3-6 parts of an antioxidant component, 1-2 parts of white oil and 0.1-0.5 part of a lubricant, and the toughening agent component comprises polypropylene, expanded polystyrene and chlorinated polyethylene. According to the invention, coffee residue is mixed for preparation so as to reuse the waste coffee residue, the prepared polypropylene particles contain fiber components, and the performance of the material is improved.

Description

technical field [0001] The invention relates to the technical field of polypropylene particle preparation, in particular to a preparation process of recycled coffee grounds plant fiber polypropylene particles. Background technique [0002] With the upgrading of products and increased investment in material recycling and reuse, polypropylene materials are widely used in medical treatment, automobiles, home appliances, gardens, and daily use due to their low density, excellent heat resistance, good fatigue resistance, and low price. In industries such as polypropylene, the preparation of polypropylene materials into devices can be recycled and has the advantages of light weight. [0003] The existing polypropylene particles are prepared in a complicated manner, are not prepared from plant fibers, and have poor environmental performance. Contents of the invention [0004] The purpose of the present invention is to solve the disadvantages of the existing polypropylene particl...
