Problems solved by technology

The disadvantages of these partition wall materials are that they are heavy, time-consuming and labor-intensive to assemble, and the sound and heat insulation effect of the partition wall is poor.
Although some people have studied new materials to replace traditional partition wall materials, these new materials do not meet the standards for practical use, and the manufacturing process is complicated. Therefore, there is no new type of partition wall that is reliable, heat-insulated and easy to install on the market. plate

Embodiment 1

[0029] Use the raw material of 20% by weight of perlite, 70% of cement, 5% of methyl cellulose (MC), and 5% of redispersible latex powder of ethylene-vinyl acetate copolymer to prepare the building wall of the present invention plate. The weight ratio of water to other raw materials is 1:1.

[0030] First, methyl cellulose (MC) is mixed with water, stirred with a stirrer, and then redispersible latex powder is added to the mixture under stirring conditions to obtain glue; Liquid mixed with perlite and cement to prepare a slurry; the slurry is added to the mold to form a layer of slurry, paved, and then a layer of wire mesh is laid on the layer of slurry, and then the layer of wire Continue to add slurry on the net; then lay a layer of silk screen on the layer of slurry, and mold the mold filled with slurry at a pressure of 80 tons per square meter; release the pressure from the mold and demould. The molded siding after demoulding is subjected to a 30-day health-preserving tr...

Embodiment 2

[0032] The building wallboard of the present invention is prepared by using the raw materials of 50% of perlite, 40% of cement, 1% of cement, and 5% of redispersible latex powder whose main component is ethylene-vinyl acetate-ethylene tertiary carbonate copolymer. The weight ratio of water to other raw materials is 1:0.8.

[0033] First, hydroxyethyl cellulose (HEC) is mixed with water, stirred with a stirrer, and then redispersible latex powder is added to the mixture under stirring conditions to obtain glue; The glue is mixed with perlite and cement to make a slurry; the slurry is added to the mold to form a layer of slurry, which is paved, and then a layer of wire mesh is laid on the layer of slurry, and then the layer Continue to add slurry on the screen; then lay another layer of screen on the layer of slurry, then continue to add slurry on the layer of screen, and then lay another layer of wire on the layer of slurry Net, mold the mold filled with slurry, the pressure i...

Embodiment 3

[0035] The weight ratio used is 70% perlite, 22% cement, 0.3% methyl cellulose (MC), 0.5% hydroxypropyl methyl cellulose (HPMC), 1.2% glass cellulose, and the main component is vinyl acetate-tertiary carbonic acid The composite rubber powder of ethylene-acrylic acid-organic silicon copolymer is used as the raw material of 6% to prepare the building wallboard of the present invention. The weight ratio of water to other raw materials is 1:1.2.

[0036] First, methyl cellulose (MC) and hydroxypropyl methyl cellulose (HPMC) are mixed with water, stirred with a stirrer, and then compound rubber powder is added to the mixture under stirring conditions to obtain a glue solution; Mix the glue with perlite and cement under agitation to make a slurry; add the slurry to the mold to form a layer of slurry, pave it, and then lay a layer on top of the layer of slurry screen, and then continue to add slurry on top of this layer of screen; Lay a layer of silk screen on it, and mold the mold...

Abstract

The invention provides a building wallboard, which is produced by adding mortar in a mould and then performing compression moulding, wherein the mortar is prepared by adding water in raw materials containing perlite and one material selected from cement, gypsum or the mixture of the cement and the gypsum, and then stirring. More preferably, the density of the building wallboard after being compression-moulded and dried is 100-350 kg / m<3>. More preferably, the raw materials further contain cellulosic substances and adhesive powder. More preferably, the weight ratios of the perlite, the material selected from cement, gypsum or the mixture of the cement and the gypsum, the cellulosic substances, and the adhesive powder are as follows: the perlite: 5-85%, the material selected from cement, gypsum or the mixture of the cement and the gypsum: 10-90%, the cellulosic substances: 0.05-8%, and the adhesive powder: 0.2-15%. The building wallboard produced according to the invention has high stress intensity, high heat-insulating performance and high sound-insulating performance, can be used as a partition wall of an indoor space in a building, an outdoor heat-insulating material, and a wall material of a temporary building, and has excellent weatherability.

Description

technical field [0001] The present invention relates to a building material, in particular to a building formwork, and more particularly to a building wall panel prepared by molding. Background technique [0002] In terms of architecture, after the main external structure is completed, according to the design of the actual use of the interior space, it is necessary to separate the large interior space with a partition wall. Traditionally used partition wall materials are bricks, hollow bricks, or lightweight bricks. The disadvantages of these partition wall materials are that they are heavy, time-consuming and laborious to assemble, and the sound insulation and heat insulation effect of the partition wall is poor. Although some people have studied new materials to replace traditional partition wall materials, these new materials do not meet the standards for practical use, and the manufacturing process is complicated. Therefore, there is no new type of partition wall that i...
