Embodiment 1

[0039] Embodiment 1: This interior wall environmental protection waterproof putty comprises base material and powder, and the weight proportion of base material and powder is: base material 1 part, powder material 5 parts; wherein base material mainly comprises modified polyvinyl alcohol , cellulose solution and water, its weight ratio is: 40 parts of modified polyvinyl alcohol, 40 parts of cellulose solution, 5 parts of water; The powder material of the present invention comprises white cement, calcium carbonate, gray calcium and talcum powder , Its weight ratio is: 15 parts of white cement (preferably select the above grade cement of 425#), 35 parts of calcium carbonate, 5 parts of ash calcium, 10 parts of talcum powder.

[0040] Among them, the modified polyvinyl alcohol produced by our company is made of 1788 type polyvinyl alcohol (10-12% in weight ratio) and acrylate (about 2% in weight ratio), functional additives (coupling agent X1 , about 0.5‰) after copolymerization ...

Embodiment 2

[0042] Embodiment 2: The difference with Embodiment 1 is that this interior wall environmental protection waterproof putty includes base material and powder, and the weight ratio of base material and powder is: base material 1 part, powder material 6 parts; The base material mainly includes modified polyvinyl alcohol, cellulose solution and water, and its weight ratio is: 50 parts of modified polyvinyl alcohol, 50 parts of cellulose solution, and 0 part of water; the powder of the present invention includes white cement , Calcium carbonate, gray calcium and talcum powder, its weight ratio is: 30 parts of white cement (preferably select the above grade cement of 425#), 45 parts of calcium carbonate, 10 parts of gray calcium, 15 parts of talcum powder.

Embodiment 3

[0043] Embodiment 3: This interior wall environmental protection waterproof putty comprises base material and powder, and the weight ratio of base material and powder is: base material 1 part, powder material 8 parts; Wherein base material comprises modified polyvinyl alcohol, The weight ratio of cellulose solution, polyacrylamide and water is: 40 parts of modified polyvinyl alcohol engineering glue, 40 parts of cellulose solution, 10 parts of polyacrylamide, and 5 parts of water. The powder mainly includes white cement and composite filler, and its weight ratio is: 15 parts of white cement, 50 parts of composite filler, calcium carbonate or ash calcium or talcum powder or old powder for composite filler. The cellulose solution in the formula is the main water-retaining agent and thickener, and at the same time it can play a lubricating role to increase the construction performance of the putty. Polyacrylamide is the main water reducer and thickener at the same time. The ash ...

Abstract

the invention discloses an environmental-protective water-proof putty of internal wall, which consists of base material and powder material, wherein the weight rate of base material and powder material is 1: 5-8; the base material contains 40-50% modified polyvinyl alcohol, 40-50% fiber solution and 5-10% water; the powder material concludes 15-30% white cement and 50-70% compound filler. the invention improves constructing efficiency, which saves paint and increases hiding power, fullness and leveling property.

Description

technical field [0001] The invention relates to the field of building materials, and mainly relates to an environment-friendly and waterproof putty for inner walls. Background technique [0002] A good interior wall putty can save paint and increase the hiding power, fullness and leveling of the paint, thereby improving the decorative effect of the paint. The knot strength, water resistance and other properties are also uneven, and the quality is also unstable. Now the putty on the construction site basically uses decorative white cement, old powder, and gypsum as powder materials, and low-solid construction glue and cooked rubber powder are mostly used as base materials. The putty prepared in this way is not water-resistant, has low strength and is easy to crack. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned deficiencies, and provide a kind of inner...
