Lime-based plaster formula

Abstract

The invention discloses a lime-based plaster formula, wherein the components comprise, by weight, 74-82 g of building lime, 294-306 g of building gypsum, 611-629 g of heavy calcium powder, 1-4 g of wood fiber, 1-3 g of cellulose ether, 0.2-1 g of a retarder, 1-3 g of poly-acid styrene, 1-3 g of foamed polystyrene, 1-4 g of starch ether, and 1-3 g of a hydrophobic agent. The lime-based plaster of the present invention has advantages of reasonable ratio design, low cost, moisture prevention, weathering prevention and extremely strong heat insulation capability.

Description

technical field [0001] The invention belongs to the technical field of new building materials, in particular to a lime-based plastering formula. Background technique [0002] Plastering works are divided into internal plastering and external plastering. Usually, the plastering located in various parts of the interior is called internal plastering, such as floors, ceilings, dadoes, baseboards, inner stairs, etc.; the plastering located in various parts of the outdoors is called external plastering, such as external walls, canopies, Balconies, roofs, etc. Internal plastering is mainly used to protect the wall, improve indoor sanitary conditions, enhance light reflection, and beautify the environment; in rooms that are susceptible to moisture or acid and alkali corrosion, it mainly plays the role of protecting the wall, ceiling and floor. The existing plastering mix ratio is unreasonable, cannot be applied to the needs of existing production and life, the cost is high, and th...
