Problems solved by technology

After the blocks made of this material are built into the wall, the inner and outer surfaces need to be plastered with cement mortar, so the construction is more complicated; secondly, it still has the problems and defects of large capacity and poor thermal insulation effect

Abstract

This invention relates to a lightweight heat-insulating porous wall material and its blocks. The lightweight heat-insulating porous wall material is composed of: Portland cement 20-50 parts, lightweight sintered magnesium oxide 10-20 parts, hydrogen peroxide foamer 5-10 parts, rosin soda soap 5-10 parts, calcium stearate stabilizer 2-6 parts, naphthalene 1-5 parts, straw or wood powder or fly ashes filler 10-20 parts, and water. The block comprises a concrete inner-interlayer, a concrete outer-interlayer, more than two insulating connecting bars disposed between the concrete inner-interlayer and the concrete outer-interlayer, and the lightweight heat-insulating porous wall material filled between the concrete inner-interlayer and the concrete out-interlayer. The lightweight heat-insulating porous wall material has such advantages as small volume and low heat conductivity. The block has such advantages as high compressive strength, stable morphology, good fire and water resistance, easy cutting and good heat insulation.

Description

1. Technical field [0001] The present invention relates to the field of building wall materials, in particular to the field of lightweight thermal insulation porous wall materials and block manufacturing using the materials. 2. Background technology [0002] Existing building insulation blocks are made by filling the inner cavity of the block with polystyrene boards or polystyrene particles and using cement prefabrication. There are thermal bridges and cold bridges in the blocks, and the insulation effect is poor. Therefore, insulation materials must be pasted on the outside of the blocks to achieve the insulation effect. Although it has the advantages of thermal insulation, its disadvantages are complicated construction and high cost. And under high temperature conditions in the event of a fire, foam plastics will thermally decompose and release toxic and harmful gases. For example, polyvinyl chloride foam will release chlorine gas after thermal decomposition, and polystyr...
