Multifunctional waterproof heat-insulating powder

Abstract

The invention discloses multifunctional waterproof heat-insulating powder which comprises the following raw materials in percentage by weight: 60-80 percent of white cement, 2-10 percent of U-shaped expansion agent, 2-10 percent of calcium stearate, 5-10 percent of hollow microsphere, 8-20 percent of quartz powder, 0.1-0.5 percent of cellulose ether, 1-2 percent of water redispersible polymer powder, 0.5-1 percent of sodium hexametaphosphate, 1-8 percent of accelerating agent and 2-10 percent of sulphate aluminum cement. With the white cement, the U-shaped expansion agent, the alcium stearate and the quartz powder as main raw materials and with the hollow microsphere, the cellulose ether, the water redispersible polymer powder, the sodium hexametaphosphate, the accelerating agent and the sulphate aluminum cement as auxiliary material, the multifunctional waterproof heat-insulating powder has the advantages that the early strength and the waterproof property of mortar are improved and the impermeable capability of a roof is improved; and meanwhile, the multifunctional waterproof heat-insulating powder has the characteristic of convenience in construction. The multifunctional waterproof heat-insulating powder is simple in operation of a preparation process, and convenient for large-scale production, can be used for cooling a garret and is widely used for waterproof construction of toilets, basements and water pools.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a multifunctional waterproof and heat-insulating powder. When using, you only need to add water at the construction site and stir it into a slurry with a certain consistency. It has weather resistance, good water resistance, and remarkable heat insulation effect. Background technique [0002] At present, waterproof coatings are roughly divided into two categories, namely water-emulsion and solvent-based. Most of the water-emulsion type is added with asphalt emulsion to form a black coating film, which is not conducive to the heat insulation and cooling of the roof in summer. Among the solvent type, most of them use coal tar or synthetic resin or modified asphalt. This kind of coating is harmful to the human body and is not environmentally friendly. , its black coating is not conducive to the cooling and heat insulation of the roof. [0003] The current th...

Most of the water-emulsion type is added with asphalt emulsion to form a black coating film, which is not conducive to the heat insulation and cooling of the roof in summer. Among the solvent type, most of them use coal tar or synthetic resin or modified asphalt. This kind of coating is harmful to the human body and is not environmentally friendly. , its black coating film is not conducive to the cooling and heat insulation of the roof

[0003] The current thermal insulation materials mainly include polystyrene particle thermal insulation mortar and expanded perlite thermal insulation mortar, but polystyrene particle thermal insulation mortar is flammable, poor fireproof performance, large rebound and shrinkage during construction.

Expanded perlite thermal insulation mortar has the disadvantages of high water absorption rate, easy pulverization, large slurry shrinkage rate, low later strength and easy cracking.
