Embodiment 1

[0023] The weight ratio is 75 parts of PVC resin, 75 parts of calcium carbonate powder, 8 parts of bamboo and wood fiber powder, 5 parts of calcium zinc stabilizer, 0.8 parts of AC foaming agent (azodicarbonamide), 5 parts of The foaming regulator, 0.4 parts of stearic acid and 0.6 parts of PE wax are added to the high-speed mixer and mixed with high temperature and heat to 110-130 ℃, and then low temperature and cold mixing to 35-55 ℃ for discharging. Then, the mixed ingredients discharged from the discharge are conveyed to the extruder to complete the extrusion of the base material of the bamboo and wood fiber wallboard. Finally, the extruded substrates were coated with PVC and the finished products were tested for peel strength and bending strength.

Embodiment 2

[0025] The weight ratio is 75 parts of PVC resin, 75 parts of calcium carbonate powder, 8 parts of bamboo fiber powder, 5 parts of calcium zinc stabilizer, 0.8 parts of AC foaming agent, 5 parts of foaming regulator, 0.4 Parts of stearic acid, 0.5 parts of PE wax, 0.5 parts of PEG with a molecular weight of 6000 and 3 parts of AIM resin are added to a high-speed mixer and mixed with high temperature and heat to 110-130°C, and then mixed with low temperature and cold to 35-55°C. material. Then, the mixed ingredients discharged from the discharge are conveyed to the extruder to complete the extrusion of the base material of the bamboo and wood fiber wallboard. Finally, the extruded substrates were coated with PVC and the finished products were tested for peel strength and bending strength.

Embodiment 3

[0027] The weight ratio is 75 parts of PVC resin, 75 parts of calcium carbonate powder, 8 parts of bamboo fiber powder, 5 parts of calcium zinc stabilizer, 0.8 parts of AC foaming agent, 5 parts of foaming regulator, 0.4 Parts of stearic acid, 0.6 parts of PE wax, 0.3 parts of PVA fiber and 2 parts of MBS resin are added to the high-speed mixer to heat and mix at high temperature to 110-130°C, and then cold-mix at low temperature to 35-55°C for discharging. Then, the mixed ingredients discharged from the discharge are conveyed to the extruder to complete the extrusion of the base material of the bamboo and wood fiber wallboard. Finally, the extruded substrates were coated with PVC and the finished products were tested for peel strength and bending strength.

Abstract

The invention discloses a bamboo-wood fiber wallboard and a preparation method thereof. The base material of the bamboo-wood fiber wallboard comprises 75-100 parts by weight of PVC resin, 75-100 parts of calcium carbonate powder, 2-15 parts of Bamboo fiber powder, 5-7 parts of stabilizer, 0.8-1 part of foaming agent, 5-8 parts of foam regulator, 0.4-1 part of stearic acid, 0.5-1 part of PE wax, 0.3 ~1.1 parts of substrate surface hydrophilic modifier and 2~4 parts of acrylate impact modifier, a kind of preparation method of bamboo wood fiber wallboard comprises a) mixing, b) extruding and c) covering membrane. In the present invention, by adding a substrate surface hydrophilic modifier such as polyethylene glycol or polyvinyl alcohol and adding an acrylate impact modifier such as AIM resin or MBS resin, the wallboard substrate and PUR hot-melt adhesive can be improved. Increase the junction strength, broaden the width of processing conditions during lamination, and enhance the mechanical properties of wallboard substrates.

Description

【Technical field】 [0001] The invention relates to the technical field of wallboards, in particular to the technical field of a bamboo-wood fiber wallboard and a preparation method thereof. 【Background technique】 [0002] With the improvement of living standards, people's requirements for the quality of interior decoration materials have gradually increased, and interior decoration materials are constantly being updated. Bamboo and wood fiber integrated wallboard is made of PVC, calcium powder, bamboo and wood fiber and other raw materials after extrusion processing to form a wood-plastic substrate, and then the surface of the substrate is pasted with PUR hot melt adhesive and PVC film, PP film or wall covering. Composite decoration materials. Bamboo and wood fiber integrated wall panels are favored by the majority of owners once they are launched on the market due to their advantages of fast decoration and environmental protection. [0003] PUR (Polyurethane Reactive), Chi...
