Heat-insulating mortar additive, coal ash polyphenyl particle heat-insulating mortar and method for making same

Abstract

The present invention discloses a heat-preservation mortar additive agent, which comprises the follow components: if calculated by weight ration, 5 -10 percent of high molecular polymer, 0.5-1.5 percent of thickening agent, 0.5-2 percent of reinforcing fibre material, 0.01-0.05 percent of wetting agent, 0.01-0.1 percent of air entraining agent, 0.05-0.3 percent of antiseptic agent, 0.05-0.2 percent of pH regulator and the other percent of water. The present invention is to prepare the polyphenyl grain heat-preservation mortar by adding the heat-preservation mortar additive agent including a plurality of modifying agents. The present invention overcomes the limitation of mixing with powder coal ash in the polyphenyl grain heat-preservation mortar; the mixing weight ratio for the powder coal ash reaches up to 40 percent, but the technical performance for the product can reach or be better than the quality standard required in Table 7 of JG158-2004 ''Outer Wall Heat Preservation System of Glue Powder Polyphenyl Grain''.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a thermal insulation mortar additive and polyphenylene particle thermal insulation mortar for construction containing high fly ash using the additive. Background technique [0002] In recent years, polystyrene particle thermal insulation mortar has been widely used in internal and external thermal insulation projects of building walls. There have been many research projects and patented technologies for polyphenylene particle thermal insulation mortar. Many of these research projects and patented technologies are mixed with industrial waste. The example of fly ash has broadened the application range of fly ash, and is environmentally friendly. However, there have always been some difficulties in the excessive addition of fly ash. The amount of fly ash is generally not more than 40% by weight on a dry basis. %.
