Embodiment 1

[0073] This embodiment provides a board, wherein the raw material composition and preparation method of the board are as follows.

[0074] As shown in Table 1 and Table 2, the raw materials were weighed according to the mass ratio of polyvinyl chloride: calcium carbonate: wood: auxiliary additive = 40:20:30:10. Under the temperature condition of 80 degrees Celsius, the raw materials are mixed and stirred to obtain the mixed materials. Under the temperature condition of 200 degrees Celsius, the mixed material is extruded to obtain a composite sheet. Among them, the auxiliary additives include: foaming agent, stabilizer and coupling agent, and the mass ratio of the three is: foaming agent:stabilizer:coupling agent=4:3:3. The foaming agent in this embodiment is an azodicarbonamide foaming agent, the stabilizer is a dibutyltin stabilizer, and the coupling agent is a titanate coupling agent.

Embodiment 2

[0076] This embodiment provides a board, wherein the raw material composition and preparation method of the board are as follows.

[0077] As shown in Table 1 and Table 2, the raw materials were weighed according to the mass ratio of polyvinyl chloride: calcium carbonate: wood: auxiliary additive = 45:20:25:10. Under the temperature condition of 90 degrees Celsius, the raw materials are mixed and stirred to obtain the mixed materials. Under the temperature condition of 210 degrees Celsius, the mixed material is extruded to obtain a composite sheet. Among them, the auxiliary additives include: foaming agent, stabilizer and coupling agent, and the mass ratio of the three is: foaming agent:stabilizer:coupling agent=4:3:3. The foaming agent in this embodiment is an azodicarbonamide foaming agent, the stabilizer is a dioctyltin stabilizer, and the coupling agent is a silane coupling agent.

Embodiment 3

[0079] This embodiment provides a board, wherein the raw material composition and preparation method of the board are as follows.

[0080] As shown in Table 1 and Table 2, the raw materials were weighed according to the mass ratio of polyvinyl chloride: calcium carbonate: wood: auxiliary additive = 50:15:25:10. Under the temperature condition of 100 degrees Celsius, the raw materials are mixed and stirred to obtain the mixed materials. Under the temperature condition of 220 degrees Celsius, the mixed material is extruded to obtain a composite sheet. Among them, auxiliary additives include: foaming agent, stabilizer, coupling agent, lubricant, toner and reinforcing fiber. The mass ratio of each component in the auxiliary additive is: foaming agent: stabilizer: coupling agent: lubricant: toner: reinforcing fiber = 1.5:1.5:1.5:1.5:2:2. The foaming agent of the present embodiment is an azodicarbonamide foaming agent, the stabilizer is a dioctyltin stabilizer, the coupling agent ...
