Abstract

The invention relates to the technical field of building materials, in particular to waterproof and moistureproof putty powder capable of defoaming and leveling, which is prepared by mixing the following materials: Portland cement, calcium hydroxide, quartz sand, ground calcium carbonate, active vitrified micro bubbles, hydroethyl cellulose, lignin, amylase and anti-cracking fibers. The use methodof the water-resistant moisture-proof putty capable of defoaming and leveling comprises the step of uniformly mixing the materials with water, wherein the solid-liquid mass ratio is 5-10:3. Comparedwith the prior art, the invention has the following beneficial effects: the physical properties of the material are changed, wood fibers and cellulose ether are added on the basis of the prior art toplay roles in retaining water, ventilating and condensing, light vitrified micro bubbles and machine-made sand are added to fill pores on the surface, and the combination of the light vitrified microbubbles and the machine-made sand achieves the effects of ventilation and foam inhibition; therefore, the purpose of defoaming is achieved; the product meets the standards of GB 18582-2001 and JG / T 298-2020 (water-resistant type N), and the surface of the product is flat and smooth, free of bubbles and free of needle holes.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a water-resistant and moisture-proof putty powder capable of defoaming and leveling, a preparation method and an application method thereof. Background technique [0002] Product technical disadvantages of the existing bottom putty: [0003] 1. A large number of air bubbles and pinholes will be generated on the wall and ceiling when scraping the cement base; [0004] 2. Due to the large amount of air bubbles generated by the bottom putty, it will lead to labor-intensive labor. Only after multiple batches of scraping or repairing can the leveling effect be achieved; [0005] 3. Due to the thickness of the bottom layer, the paint layer of the wall will crack, and there is a risk of mold falling off. [0006] In view of this, apply for this patent. Contents of the invention [0007] In order to overcome the deficiencies of the existing technology and solv...
