Light-weight partition wall board and manufacturing method thereof

Abstract

The invention provides a light-weight partition wall board and a manufacturing method thereof. The light-weight partition wall board contains the following components by weight: 350-400kg of cement, 100-180kg of ceramsite, 108-240kg of secondary coal ash, 5kg of monofilament fibers, 0.2-0.3kg of an SY-F60 composite foaming agent, 20ml of triethanolamine and 460-520kg of water. The light-weight partition wall board has the advantages that production investment is low, raw materials can be purchased nearby and production efficiency is high; moreover, the partition wall board also has the advantages of high quality, light weight, high strength, long service life, heat preservation, sound insulation, fire prevention, environment friendliness and the like.

Description

technical field [0001] The invention relates to a new type of building material, in particular to a lightweight partition board produced by foaming ordinary portland cement and a manufacturing method thereof. Background technique [0002] Ordinary Portland cement foamed lightweight partition board products are suitable for a wide range of products, suitable for high-rise residential quarters, hospital office buildings, hotels, etc., and non-load-bearing internal partition walls for civil and industrial buildings. The existing technology is similar in production In the process of the partition wall board, one is to use special cement such as high alumina cement or sulphoaluminate cement, perlite (polystyrene particles), and plant foaming agent for processing and production. In the production process, there are : The prepared foam has poor stability and high raw material cost. Its products have problems such as: heavy weight, low strength in the later stage, and poor thermal ...

AI Technical Summary

Problems solved by technology

[0002] Ordinary Portland cement foamed lightweight partition board products are suitable for a wide range of products, suitable for high-rise residential quarters, hospital office buildings, hotels, etc., and non-load-bearing internal partition walls for civil and industrial buildings. The existing technology is similar in production In the process of the partition wall board, one is to use special cement such as high alumina cement or sulphoaluminate cement, perlite (polystyrene particles), and plant foaming agent for processing and production. In the production process, there are : The prepared foam has poor stability and high raw material cost

Its products have problems such as: heavy weight, low strength in the later stage, and poor thermal insulation and fire resistance

The other is a product that is foamed with ordinary Portland cement and processed through an autoclave for 10-14 hours with high-temperature and high-pressure steam curing. Its main shortcomings are: large investment in production equipment, large production energy consumption, and product cost Big

[0003] The patent application number is: 200910019411.4 A kind of ceramsite commercial concrete lightweight partition wall board and its preparation method, the partition wall board produced by it exists: first, the product surface density is relatively large, and the 90mm thick partition wall board weighs 86 per square meter -93kg, compared with ceramsite ordinary cement foam partition wall board, it weighs 28-32 kg per square meter, and it weighs 10-15kg per square meter compared with the partition wall board produced with perlite, which makes installation and construction more difficult. The labor cost is high; the second is that due to the flat mold production, one board surface is manually finished, and the flatness of the board surface is not high

[0004] The patent application number is 200510034004.2 for the light-weight fireproof partition wall board and its preparation method. There are: first, the raw material bauxite cement or aluminate cement used in the product belongs to special cement, and its price is high (the ex-factory price per ton is 550-1500 yuan) , the ex-factory price of ordinary cement is 370-390 yuan per ton), and the production cost is high; the second is that the partition board produced by aluminate cement has good early strength but poor later strength, and as time goes by, the strength of the board shows a downward trend

[0005] The patent application number is 201210161251.9 and the patent application number is 201210161242.X. The production process of concrete foamed lightweight partition wall panels of Anwei Dehe Building Energy Saving Technology Co., Ltd. has: first, the investment in building a factory is large, and the area is large. In addition to investing in the purchase of molds, it is also necessary to invest in the construction of a constant temperature cellar; second, the energy consumption is high, because the cast mold needs to be cured in a constant temperature cellar for 10-14 hours by high-temperature and high-pressure steam before it can be demoulded, and its coal or electricity consumption Large, not conducive to energy saving and environmental protection, high production costs, the products produced have no competitive advantage in the market; third, the strength is poor, because all the cementitious materials (cement and fly ash) used in the production formula have no coarse aggregate , its product strength is relatively low
