Dry-mixed plastering mortar

Abstract

The invention discloses dry-mixed plastering mortar. According to the formula, the dry-mixed plastering mortar comprises machine-made sand, cement, coal ash powder, steel waste residue powder, cellulose ether, pigment and heat preservation dry powder. The dry-mixed plastering mortar is prepared from the following components, by weight: 750-800 parts of machine-made sand, 110-120 parts of cement, 30-40 parts of coal ash powder, 20-30 parts of steel waste residue powder, 0.08-0.15 part of cellulose ether, 3-5 parts of pigment and 4-6 parts of heat preservation dry powder; and by adding the steelwaste residue powder, the use amount of the coal ash powder in the formula is reduced, and the cost is reduced; meanwhile, recycling of steel waste residues is facilitated, and environmental protection is facilitated; by adding the heat preservation dry powder which is reasonably prepared from the components, the heat preservation performance of the dry-mixed plastering mortar is improved; gaps among mortar molecules are reduced, the waterproof performance of the mortar is improved, the cracking and falling phenomena of the mortar after use are avoided. The natural mineral pigment is added into the formula, so that the color of the mortar is enriched, and the selling point of the mortar is increased.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a dry-mixed plastering mortar. Background technique [0002] Dry-mixed plastering mortar is made of high-quality cement as the main bonding base material, precisely screened and dried river sand, and high-quality water-retaining thickening materials. It is a special improved dry powder mortar designed and produced with high-quality polymers. It can be used only after adding water on the construction site and stirring it mechanically as required. [0003] Dry-mixed plastering mortar can be used for the plastering and plastering of various types of masonry and ceilings on the interior and exterior walls of buildings. Most of the dry-mixed plastering mortars on the market are gray and the color is relatively single. If it is painted on the exterior wall, the color is too monotonous. , needs to be painted or tiled, which greatly increases the cost, and now the dry-mixed mortar on t...

Problems solved by technology

[0003] Dry-mixed plastering mortar can be used for the plastering and plastering of various types of masonry and ceilings on the inner and outer walls of buildings. Most of the dry-mixed plastering mortars on the market are gray and the color is relatively single. If it is painted on the outer wall, the color is too monotonous. , needs to be painted or tiled, which greatly increases the cost, and most of the dry-mixed mortars on the market now use river sand and coal ash powder as the main ingredients, which is high in cost and reduces the profit margin of mortar production. The thickness is small, there are large gaps between the molecules, the thermal insulation effect is poor, and the thermal insulation performance of the mortar is reduced
