Embodiment 1

[0016] In the production method of the nano-polymer bamboo-wood fiber integrated wallboard of the present invention, the components by weight of the raw materials include polyvinyl chloride resin 10-15, calcium carbonate powder 21-23, bamboo wood powder 0.5-0.6, stearic acid 5-7, foaming agent 0.7-0.8, foam regulator 0.6-0.7, calcium-zinc composite stabilizer 49-52; the production steps are:

[0017] A. Put the raw materials into the hot mixer and mix them evenly at high speed, raise the temperature to 110°C-115°C and keep for 5 minutes. ℃-58℃, forming a mixed material, the best cooling temperature is 58℃;

[0018] B. Transfer the mixed material into the extrusion molding machine. The mixed material enters the confluence core after being heated step by step, and then enters the mold and is heated and formed to form a cavity structure with multiple chambers, which can form air convection circulation The molded semi-finished product; the cavity structure refers to a plurality o...

Abstract

The invention relates to a production method for a nano high molecular bamboo fiber integrated wallboard. The nano high molecular bamboo fiber integrated wallboard comprises the following raw materials: polyvinyl chloride resin, calcium carbonate powder, bamboo powder, stearic acid, a foaming agent, a foaming agent regulator and a lead, calcium and zinc salt stabilizer. The production method comprises the following production steps: uniformly stirring and mixing the raw materials, and transferring the raw materials to an extruding forming machine to form a formed semi-product with a unique cavity configuration; pulling and stretching the semi-product, and covering the semi-product with a sizing mold for vacuumized extruding forming so as to form a wallboard substrate; and laminating the wallboard substrate at a high temperature, and then cutting the wallboard substrate according to a set specification to prepare the nano high molecular bamboo fiber integrated wallboard.

Description

technical field [0001] The invention relates to a production method of a nano-polymer bamboo-wood fiber integrated wallboard, in which raw materials such as hot-melt resin, modified filler, functional additive, adhesive, etc. are passed through a foaming extrusion process, a traction shaping process, and a film coating process. process, to prepare wallboard materials with simulation effects, which are used for decoration of the interior walls of buildings. Background technique [0002] Chinese patent 201611069029.0 discloses a composite wallboard. The raw material coils are put into the embossing unit, and the processed raw material boards are put into the cold bending forming unit. A polyurethane layer is laid, and a fireproof layer is laid on the polyurethane layer to make a composite wallboard. This composite wallboard has the characteristics of quick installation, thermal insulation, sound and noise reduction, light weight and wear resistance. [0003] But the thicknes...
