Problems solved by technology

At present, polyvinyl alcohol 107 series glue or redispersible latex powder supplemented by starch ether and other polymer products are generally used in the market as thickeners, water retention agents, and binders, but due to the limitations of the essential properties of these chemical products and the thermal insulation Determined by the filler structure of the mixed mortar, the cohesion, thickening, water retention, construction and other issues that should be possessed in the mortar cannot be satisfied, so the product quality is not guaranteed, and the cost is still relatively high

Abstract

The invention discloses a multifunctional additive of thermal insulation dry-mixing slurry, which comprises the following parts: sodium carboxymethylcellulose, polyvinyl alcohol powder, urea-formaldehyde resin, polyethylene oxide (PEO), alta-mud and wood cellulose. The additive possesses even dispersion, which saves cost and protects environment.

Description

Technical field [0001] The invention relates to the field of chemical building materials. Background technique [0002] The external wall thermal insulation dry-mixed mortar series products have been developed in recent years according to the spirit of national wall material innovation and promotion of energy-saving buildings. Although there are many kinds of thermal insulation materials on the market, no matter what kind of thermal insulation materials, they are inseparable from adhesives, water-retaining agents, and anti-cracking agents. At present, the market generally uses polyvinyl alcohol 107 series glue or redispersible latex powder supplemented with starch ether and other polymer products as thickeners, water-retaining agents, and binders. However, due to the limitations of the essential properties of these chemical products and the heat preservation and dryness Determined by the filler structure of the mixed mortar, the cohesiveness, thickening, water retention, construc...
