Problems solved by technology

However, due to the characteristics of the antique wood-plastic material itself, it is difficult to bend and re-shape the antique wood-plastic after the production is completed, which limits the artistic appreciation of the final product
Especially for the backrest strip of the chair, the existing technology cannot form the wood-plastic strip into an ideal curved arc, so other materials can only be used instead

Abstract

The invention discloses a forming process for an antique wood-plastic chair backrest strip. The forming process comprises the following steps: step I of cutting wood-plastic strips into wood-plastic strips according to a specified dimension; step II of placing the wood-plastic strips into an oven to soften; step III of placing the softened wood-plastic strips into a mould; step IV of placing the mould with the wood-plastic strips into water to soak; and step V of taking out the mould from water, taking out the wood-plastic strips in the mould to dry in air, thereby accomplishing forming of thebackrest strip. The forming process for the antique wood-plastic chair backrest strip disclosed by the invention can bend and form antique wood-plastic, improves use, in the furniture field, of antique wood-plastic, and has the advantages of being simple in operation, being good in forming effect, not damaging characteristics of the wood-plastic material, and the like.

Description

technical field [0001] The invention belongs to the technical field of wood-plastic products, and in particular relates to a molding process of an antique wood-plastic chair backrest strip. Background technique [0002] Wood-plastic (wood-plastic composite material) is a new type of composite material that has been booming at home and abroad in recent years. It refers to the use of polyethylene, polypropylene and polyvinyl chloride instead of the usual resin adhesive, with more than 35% -70% of the Wood flour, rice husk, straw and other waste plant fibers are mixed into new wood materials, and then processed by extrusion, molding, injection molding and other plastic processing techniques to produce boards or profiles. Mainly used in building materials, furniture, logistics packaging and other industries. The board formed by hot extrusion after mixing plastic and wood powder in a certain proportion is called extruded wood-plastic composite board. Antique wood-plastic has th...
