Wall paint agent for porous bricks

Abstract

The invention discloses a wall paint agent for porous bricks. The wall paint agent comprises the following materials in parts by weight: 40-50 parts of inorganic cementing material, 2-5 parts of water soluble resin, 28-41 parts of aggregate, 0.1-0.5 part of modifying agent, 0.2-0.6 part of anti-cracking agent, 0.2-0.4 part of water retaining agent, 0.2-0.4 part of thickener and 10-20 parts of inorganic filler. The wall paint agent for the porous bricks prepared by the invention has the advantages that the surface tension, adhesion and strength of a painting layer with a wall body are improved, so that the wall body and the painting layer are formed into a whole, and air bubble, crack and other defects cannot easily occur; meanwhile, the thermal effect of the wall body is improved; the flatness deviation of the wall body can be ensured within 3 millimeters; the property of the painting layer with a coating thickness of only 5-8 millimeters is better than the property of a traditional cement plastering mortar layer with a thickness of 2 centimeters; only 10-15 kilograms of the paint agent is needed, and no gridding cloth is needed before construction, so that the construction cost is much lower than that of the traditional plastering mortar, and the weight of the wall body is reduced; the indoor use area and the thermal effect of the wall body are increased; and meanwhile, a waste material, i.e. coal ash is used as the raw material, so that the environmental friendliness is high.

Description

technical field

[0001] The invention relates to the field of construction, in particular to an aerated block wall plastering agent. Background technique

[0002] Aerated block is a new type of lightweight and porous building material, which has the advantages of light bulk density, high thermal insulation performance, good sound absorption and machinability. It can be made into wall blocks, thermal insulation blocks, pressed panels, floor slabs, wall panels and thermal insulation pipes. At present, aerated blocks have been widely used in load-bearing or non-load-bearing structures and pipeline insulation in industrial and civil buildings in my country, and have become an important part of new building materials. At present, aerated blocks are made into indoor walls, which are generally painted with cement mortar. However, due to the differences in strength, hardness and surface tension between the aerated blocks and the dried mortar, they cannot be integrated, and it is very ...
