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 invention relates to a building wall material, in particular to a light-weight heat-preserving porous wall material and the field of block production using the material. 2. Background technology [0002] Existing building thermal insulation blocks are prefabricated by cement and filled with polystyrene boards or polystyrene particles in the inner cavity of the block. There are thermal bridges and cold bridges in the block, and the thermal insulation effect is poor. Therefore, the thermal insulation material must be pasted on the outside of the block to achieve the thermal insulation effect. Although it has the advantage of heat insulation, its disadvantage is that the construction is complicated and the cost is high. And under high temperature conditions when a fire breaks out, foam plastics are heated and decomposed, releasing toxic and harmful gases, such as: polyvinyl chloride foam releases chlorine gas after thermal decomposition, and polys...
