Problems solved by technology

Even so, there are some obvious deficiencies in the use of wood-plastic composite materials. For example, when used for a long time, especially in the open air, aging phenomena such as cracking and fading are prone to occur under the action of light and oxygen, thereby shortening its service life and limiting its use. scope of use

Abstract

The invention relates to the technical field of composites, in particular to a production process for a wood-plastic composite park seat. The production process comprises the following steps that (1)raw materials are weighed by weight, including 100 parts of wood flour, 35-55 parts of plastic particles, 3-6 parts of lubricants, 8-14 parts of antioxygens, 5-10 parts of light stabilizers, 9-15 parts of maleic anhydride grafted plastic particles and 2-5 parts of metal particles; (2) the wood flour, the plastic particles, the maleic anhydride grafted plastic particles and the light stabilizers are mixed by an airflow mixer; (3) mixtures are subjected to fusion extrusion through a double-screw extruder and cooled and cut into wood-plastic composite aggregates; (4) the wood-plastic composite aggregates, the metal particles and the lubricants are added into the airflow mixer to be mixed uniformly; (5) the mixtures are added into the extruder for fusion, and extrusion molding is conducted toobtain ageing-resistant wood-plastic composites; and (6) the ageing-resistant wood-plastic composites are formed into the seat. The seat with high ageing-resistant performance can be obtained by uniformly mixing the raw materials.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to a production process of plastic-wood park seats. Background technique [0002] Wood-plastic composite materials use thermoplastics, including polyethylene, polypropylene, polystyrene and their copolymers, as matrix materials, and waste natural fibers such as wood powder, rice husk, wheat straw, corn stalks, and peanut shells as reinforcing phases. , and then add a small amount of chemical additives and fillers, a composite material made through a certain processing technology. It combines the main advantages of thermoplastic polymers and wood, and has the advantages of anti-corrosion, moisture-proof, moth-proof, high dimensional stability, no cracking, no warping, etc. It can be widely used as outdoor flooring, swimming pool edging, flower boxes, tree pools, Fences, trash cans, sun visors, stools, chair strips, backrest strips, leisure tabletops, signs, billboards, b...
