Problems solved by technology

There are various plate and strip products on the market. Most of the existing gypsum is made of polyvinyl alcohol, glue and water mixed into paste gypsum. The gypsum material of these gypsum boards is a moisture-absorbing material, so in It is used in some indoor environments that generate moisture and humidity. After a period of use, the gypsum board will loosen and fall off, which will damage the original shape and destroy the indoor beautification environment.

Embodiment Construction

[0009] High-strength gypsum board is composed of the following raw materials by weight: 13 parts of glass slag, 40 parts of old gypsum board powder, 5 parts of paper ash, 4 parts of fly ash, 12 parts of light filler, 5 parts of titanate , 3.7 parts of retarder, 100 parts of water, its concrete preparation steps are as follows:

[0010] 1) The glass slag and old gypsum board powder are mechanically pulverized into powder, stirred evenly according to the formula ratio, then water with a weight ratio of 9% is added, and then raw material balls with a particle size of 4.8mm are formed by a ball forming machine. Dry at 280°C for 5 hours; roast the dried raw material balls at 1400°C for 50 minutes to obtain the main material ceramsite. Mix the main material ceramsite, fly ash and light filler and add the main material ceramsite weight 25 % water, after stirring for 1.5h, enter the aging storehouse for aging, the stirring speed is 700rpm, and the stirring time is 2.5h, then air-dried...

Abstract

The invention discloses a high-strength plasterboard. The high-strength plasterboard comprises, by weight, 13 parts of broken glass, 40 parts of old plasterboard powder, 5 parts of paper strip mixed with lime mortar, 4 parts of fly ash, 12 parts of a light filler, 5 parts of titanate, 3.7 parts of a retarder and 100 parts of water. The high-strength plasterboard utilizes the broken glass, old plasterboard and fly ash as raw materials. Old plasterboard can be recycled. In production, formaldehyde and pollution are not produced. Through use of paper strip mixed with lime mortar and the retarder, gypsum strength and denseness are improved, plasterboard strength and hardness are guaranteed and a good environmental protection function is obtained.

Description

technical field [0001] The invention relates to the field of building materials used for interior decoration, in particular to high-strength gypsum boards. Background technique [0002] At present, with the improvement of people's living standards, most family houses are decorated with gypsum boards. Gypsum board is a lightweight, fire-resistant building decoration material, mostly used for indoor ceilings. There are various plate and strip products on the market. Most of the existing gypsum is made of polyvinyl alcohol, glue and water mixed into paste gypsum. The gypsum material of these gypsum boards is a moisture-absorbing material, so in It is used in some indoor environments that generate water vapor and humidity. After a period of use, the gypsum board will loosen and fall off, which will damage the original shape and destroy the indoor beautification environment. Contents of the invention [0003] The purpose of this invention is to provide a high-strength gypsum ...
