Wallboard and preparation method thereof

Abstract

The invention relates to the field of wallboard manufacturing, in particular to a wallboard and a preparation method thereof. The wallboard is made of 90-110Kg of polyvinyl chloride, 60-70Kg of dry crop straw powder, 60-70Kg of lightweight calcium carbonate, 5-6Kg of composite stabilizer, 1.5-2Kg of lubricating agent, 5-16Kg of foaming modifier, 1.4-1.6Kg of AC (activated carbon) foaming agent, 0.5-1Kg of tribasic products and 0.9-1.1Kg of plasticizer. The preparation method of a wood-plastic board includes: preparing raw materials, well mixing the raw materials, cooling the mixed raw materials, adding the raw materials treated at the last step into extruding equipment for extrusion forming after mould-head thermal forming and stock-mould flowing water cooling forming, and cutting the board subjected to extrusion forming for placement. The wallboard has better dimension stability and is high in surface strength and uniform in material quality.

Description

technical field [0001] The invention relates to the field of wall panel manufacturing, in particular to an indoor wall panel and a preparation method thereof. Background technique [0002] With the development of the national economy and the continuous development of the construction industry, the requirements for the material and performance of building materials are becoming more and more stringent, especially for the light weight of the material and the waterproof, flame retardant, anti-moth, anti-aging, Performance requirements such as anti-corrosion and heat insulation and sound insulation effects are getting higher and higher. The current building partition boards generally use ordinary cement and cement prefabricated boards. Although they have replaced the role of laterite bricks in engineering applications, problems such as overweight, high cost, and cracking of board seams have seriously hindered the quality and progress of building construction.

AI Technical Summary

Problems solved by technology

The current building partition boards generally use ordinary cement and cement prefabricated boards. Although they have replaced the role of laterite bricks in engineering applications, problems such as overweight, high cost, and cracking of board seams have seriously hindered the quality and progress of building construction. Various partition wall materials such as wooden wallboards, steel wire Shule boards, and gypsum boards developed later have effectively reduced the load of the wall on the building itself, but there are still some insurmountable defects, such as wooden wallboards. Beautiful, but easy to be deformed by moisture, insects, afraid of impact, especially afraid of fire

The steel wire Shule board is composed of foam interspersed with steel wires. Although it is easy to install, the surface plastering treatment greatly increases the weight of the wall itself and increases the project cost.

Although gypsum board has strong plasticity and light weight, it has defects such as low strength, poor sound insulation effect, moisture absorption, fear of water, difficult installation, easy deformation, and easy cracking of joints.
