Problems solved by technology

[0003] At present, a kind of plaster mortar—gypsum mortar has become a research hotspot. The interior wall plaster mortar should have good workability and high cohesive force. First, the amount of cement should be increased to meet the strength requirements of the mortar, and the amount of fly ash or slag powder should be limited. , the amount of cement is generally high, resulting in high cost of mortar
Second, the quality of mortar is prone to fluctuations. For example, the consistency of freshly mixed mortar fluctuates greatly and is difficult to control. The setting time of mortar is short, the water retention of mortar is poor, and bleeding is serious. The surface of the gray wall is prone to hollowing, cracking, etc., and the durability of the mortar is poor. Various quality problems occur in the mortar in a short period of time, which requires rework or repair of the building, which brings inconvenience and economic loss to people's lives.
[0005] However, during the use of the above-mentioned thermal insulation system, the thickness of the wall plaster is too thick, which will easily affect the indoor space. Therefore, a bottom layer with strong cohesive force is used to make the putty layer on the inner wall not easy to hollow out, shrink and crack. important

Embodiment 1

[0028]The thickness of the bottom layer is 7mm, and the thickness of the surface layer is 3mm. The bottom layer includes 15 parts of fine slag powder, 17 parts of fine sand, 45 parts of gypsum, 25 parts of cement and 6 parts of additives. Additives include 2 parts dispersed latex powder, 2 parts quick-setting agent and 2 parts defoamer. The following steps are used in the use process: the first step is to mix the bottom materials uniformly at room temperature according to the ratio. When the bottom materials are mixed, first mix the slag powder, fine sand, gypsum and cement evenly, and then add an appropriate amount of water for mixing. After the stirring is completed, add the auxiliary agent and continue to stir evenly. When mixing the bottom material, use and mix it to avoid long-term solidification, which will affect the use and bonding strength; then coat the mixed bottom material on the internal wall that has absorbed water, and coat it evenly until the surface is flat; In the ...

Abstract

The invention provides an interior wall painting material and a method thereof. The interior wall painting material comprises a bottom layer and a surface layer, wherein the bottom layer comprises superfine slag powder, fine sand, gypsum, cement and auxiliaries, the surface layer comprises putty powder, and the total thickness of the bottom layer and the surface layer is 1-10 mm. The scheme has the advantages of excellent construction performance, good physical and mechanical properties, long construction operation time, good construction effect and high construction efficiency; the construction process is simple, hollowing and cracking are avoided after the material is used, and the material is suitable for painting and leveling of all interior walls; good heat insulation performance is realized; and the material has good adhesion and workability, the painting thickness is greatly reduced, the use cost is reduced, and meanwhile, the service life of a painted wall surface is conveniently prolonged.

Description

Technical field[0001]The invention relates to the field of mortar, in particular to an interior wall painting material and a method thereof.Background technique[0002]Ordinary plastering mortar is the largest plastering mortar used in construction projects. Its function is mainly to protect the walls and the ground from the erosion of wind, rain and harmful impurities, improve the performance of moisture, corrosion, and weather resistance, and increase durability; at the same time, it can make the building surface smooth, clean and beautiful. At present, the materials used for wall painting mortar are yellow sand, river sand, cement, fly ash and other materials.[0003]At present, a plastering mortar—gypsum mortar has become a research hotspot. The interior wall painting mortar should have good workability and high adhesion. One is to increase the amount of cement to meet the strength requirements of the mortar, and the amount of fly ash or slag powder is limited. , The amount of cemen...
