Embodiment 1

[0023] Be the PVC resin of 75 parts by weight, the calcium carbonate powder of 75 parts, the bamboo wood fiber powder of 8 parts, the calcium zinc stabilizer of 5 parts, the AC blowing agent (azodicarbonamide) of 0.8 part, 5 parts The foam regulator, 0.4 parts of stearic acid and 0.6 parts of PE wax are added to the high-speed mixer and mixed at high temperature to 110-130 °C, and then cold-mixed at low temperature to 35-55 °C for discharge. Subsequently, the discharged mixed ingredients are sent to the extruder to complete the extrusion of the base material of the bamboo fiber wallboard. Finally, the extruded substrate is coated with PVC, and the peel strength and bending strength of the finished product are tested.

Embodiment 2

[0025] Be the PVC resin of 75 parts, the calcium carbonate powder of 75 parts, the bamboo wood fiber powder of 8 parts, the calcium zinc stabilizer of 5 parts, the AC blowing agent of 0.8 part, the foaming regulator of 5 parts, the foaming regulator of 0.4 parts by weight ratio 1 part of stearic acid, 0.5 part of PE wax, 0.5 part of PEG with a molecular weight of 6000 and 3 parts of AIM resin are added to a high-speed mixer and mixed at high temperature to 110-130°C, and then cold-mixed at a low temperature to 35-55°C. material. Subsequently, the discharged mixed ingredients are sent to the extruder to complete the extrusion of the base material of the bamboo fiber wallboard. Finally, the extruded substrate is coated with PVC, and the peel strength and bending strength of the finished product are tested.

Embodiment 3

[0027] Be the PVC resin of 75 parts, the calcium carbonate powder of 75 parts, the bamboo wood fiber powder of 8 parts, the calcium zinc stabilizer of 5 parts, the AC blowing agent of 0.8 part, the foaming regulator of 5 parts, the foaming regulator of 0.4 parts by weight ratio 1 part of stearic acid, 0.6 part of PE wax, 0.3 part of PVA fiber and 2 parts of MBS resin are added to a high-speed mixer and mixed at high temperature to 110-130°C, and then cold-mixed at low temperature to 35-55°C and discharged. Subsequently, the discharged mixed ingredients are sent to the extruder to complete the extrusion of the base material of the bamboo fiber wallboard. Finally, the extruded substrate is coated with PVC, and the peel strength and bending strength of the finished product are tested.

Abstract

The invention discloses a bamboo fiber wallboard and a preparation method thereof. The base materials of the bamboo fiber wallboard comprise, by weight, 75-100 parts of a PVC resin, 75-100 parts of calcium carbonate powder, 2-15 parts of bamboo fiber powder, 5-7 parts of a stabilizer, 0.8-1 part of a foaming agent, 5-8 parts of a foaming regulator, 0.4-1 part of stearic acid, 0.5-1 part of PE wax, 0.3-1.1 parts of a substrate surface hydrophilicity modifier and 2-4 parts of an acrylate impact modifier. The preparation method of the bamboo wood fiber wallboard includes the following steps: a) mixing, b) extruding and c) coating. The addition of the substrate surface hydrophilicity modifier such as polyethylene glycol or polyvinyl alcohol and the addition of the acrylate impact modifier such as an AIM resin or an MBS resin can improve the bonding strength of the substrate of the wallboard and a PUR hot melt adhesive, enlarge the processing conditions during coating and enhance the mechanical properties of the wallboard substrate.

Description

【Technical field】 [0001] The invention relates to the technical field of wallboards, in particular to the technical field of a bamboo 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 are gradually increasing, and interior decoration materials are also constantly being updated. Bamboo-wood fiber integrated wallboard is made of PVC, calcium powder, bamboo fiber and other raw materials through extrusion processing to form a wood-plastic substrate, and then pasted on the surface of the substrate with PUR hot-melt adhesive and PVC film, PP film or wall covering. Combined decoration materials. Due to its advantages of fast decoration and environmental protection, bamboo and wood fiber integrated wall panels are favored by the majority of owners once they are launched on the market. [0003] PUR (Polyurethane Reactive), the Chinese full...
