Problems solved by technology

However, most of the existing door panel base materials are MDF or solid wood, which are not environmentally friendly, and the base material is perishable, deformed by moisture, and has limitations in the use environment; it is easy to be eaten by insects; Operation; post-maintenance is more complicated, easy to crack, expand, and deform
[0003] The door paint surface of the door panel made of the above-mentioned door panel base material is generally made of polyurethane PU, which is not environmentally friendly.
As a result, the prepared door panels have problems such as easy to rot after being exposed to moisture, swelling and deformation, easy to be eroded by termites, and the content of benzene-containing substances and formaldehyde exceeds the standard, easy to crack and deform, and difficult to maintain. It is difficult to meet the needs of the market.

Abstract

The invention discloses a production method of a bamboo-wood fiber door plate, belongs to the technical field of door plate processing, and solves the problems that in the prior art, a door plate is prone to rot, expansion deformation and termite erosion after being affected with damp, the content of benzene-containing substances and formaldehyde exceeds the standard, the door plate is prone to cracking and deformation, and maintenance is difficult. The production method is characterized in that polyvinyl chloride resin, calcium carbonate and bamboo wood are adopted as raw materials and mixed;a door plate base material is formed after double-screw shearing, extrusion and water cooling forming through a shaping mold; a water-based adhesive is sprayed after the door plate base material is subjected to thickness fixing, engraving and door leaf grinding; the door plate base material is coated with a film or subjected to double fixation of UV glue; and the bamboo-wood fiber door plate is prepared. The bamboo-wood fiber door plate has the characteristics of being waterproof, dampproof, insect-proof, termite-proof, high in environmental protection property, free of pollution, recyclable,free of cracking, expansion and deformation and free of maintenance.

Description

technical field [0001] The invention relates to the technical field of door panel processing, in particular to a production method of a bamboo fiber door panel. Background technique [0002] With the development of society, composite materials are widely used in various industries. However, most of the existing door panel base materials are MDF or solid wood, which are not environmentally friendly, and the base material is perishable, deformed by moisture, and has limitations in the use environment; it is easy to be eaten by insects; Operation; post-maintenance is more complicated, easy to crack, expand, and deform. [0003] The door paint surface of the door panel made of the above-mentioned door panel base material generally adopts polyurethane PU, which is not environmentally friendly. As a result, the prepared door panels have problems such as easy to rot after being exposed to moisture, swelling and deformation, easy to be eroded by termites, and the content of benzen...
