Inner wall light partition plate and preparing method thereof

Abstract

The invention relates to an inner wall light partition plate which is a cuboid-shaped block made of the components, by weight, of 35-45 parts of cement, 35-45 parts of coal ash, 10-20 parts of grading micro powder and 1-2 parts of crosslinking modification emulsion. The materials are stirred and mixed into slurry, then chemical foaming forming is carried out, then precise cutting is carried out, the partition plate with the length of 3000 mm, the width of 600 mm and the thickness of 90-120 mm is made, partition plates obtained after precision cutting are stacked on a steam trolley and enter a steam curing chamber for curing, and gridding cloth adheres to the upper plate face and the lower plate face of each partition plate obtained after steam processing. According to the inner wall light partition plate, an inner wall light partition plate automatic assembly line is used for production, production efficiency is high, cost is low, product quality is stable, the inner wall light partition plate has the advantages of being light, sound insulation is achieved, heat preservation is achieved, fire resistance is achieved, a large number of industrial residues are consumed, environment protection can be well achieved, and wide promotion prospect is achieved.

[0002] With the development of social economy, the country and the people pay more and more attention to energy conservation and improvement of living conditions. Building energy conservation is an important field of energy conservation work in China. The Ministry of Housing and Urban-Rural Development is vigorously promoting the integrated system of structure and thermal insulation throughout the country. Lightweight partition board is an important part of system development. How to improve its heat insulation function and sound insulation function to make the indoor environment more comfortable has become an urgent issue; lightweight partition board is a new type of energy-saving wall material , it is a wall material that looks like a hollow floor, generally composed of harmless phosphogypsum, light steel slag, fly ash and other industrial waste residues, and is cured by steam; the light partition wall board has quality Lightweight, high strength, multiple environmental protection, thermal insulation, sound insulation, respiratory humidity control, fire prevention, rapid construction, and reduced wall cost; however, most lightweight partition panels on the market today have relatively high density and low compressive strength Various disadvantages such as small size, insufficient flexural strength, poor thermal insulation performance, high water absorption, and difficult control of cracks on the board surface have seriously affected its product quality and restricted its development and promotion; therefore, it is necessary to provide a high compressive strength , low thermal conductivity, low production cost, good thermal insulation effect, and good economic benefits
