Wallboard stuffing and wallboard

Abstract

The invention discloses a wallboard stuffing and a wallboard, and belongs to the field of building materials. The wall stuffing is prepared by mixing water and cementing materials according to a weight ratio of (0.27 to 0.4) to 1, wherein the cementing materials include cement, coal ash, construction waste fine powder, polystyrene particles, a water-reducing agent, a water-proofing agent, a flame retardant and an air entraining agent. The wallboard stuffing adopts a reasonable raw material ratio, so that the mechanical strength of the wallboard is effectively improved; and meanwhile, the call on energy conservation and environmental protection of China is responded and the recycling of wastes is realized. The use of the polystyrene particles, the water-reducing agent, the air-entraining agent, the flame retardant and the water-proofing agent enables the obtained wallboard to be overall optimized. By the adoption of the above-mentioned wallboard stuffing, the overall strength of the wallboard is greatly improved, and the compressive strength can reach 10 Mpa or above; the wallboard can meet the national requirement for the compressive strength of a load-bearing wall; and furthermore, the wallboard is excellent in fireproofing, anti-penetration and endurance performance.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a wallboard filler and a wallboard. Background technique [0002] According to the wallboard materials in my country's construction industry, from solid clay bricks to non-fired solid bricks, to various types of lightweight foam bricks. At this stage, there are three types of wall panels, the first: hollow panels; the second: composite solid panels; the third: integrated solid panels. Due to the advantages of light weight, high construction efficiency and low cost, these three wallboards partially replace the three kinds of cut bricks and are accepted by the market. [0003] At present, the wallboards produced in the country are all designed and invented around the national standard of foam bricks. The compressive strength and flexural standards are very low, and the compressive strength is generally 3.5-5MPa, while the national standard requires the strength of the load-beari...

AI Technical Summary

Problems solved by technology

The compressive strength and flexural standards are very low, and the compressive strength is generally 3.5-5MPa, while the national standard requires the strength of the load-bearing wall masonry material to be above 10MPa to ensure the safe use of the building, so this type of wallboard is only It can be used in steel frame structure and concrete frame structure, and can be used as a partition wall. It cannot be used independently as a wall panel material to fully replace traditional wall panel materials.
