Abstract

The invention relates to flexible putty powder. The flexible putty powder comprises the following raw materials in parts by weight and in a compounding ratio: 20-29 parts of kaolin powder, 6-16 parts of sepiolite powder, 5-29 parts of portland cement, 1-2 parts of hydroxypropyl methyl cellulose, 2-6 parts of an exciting agent, 2-6 parts of water-soluble emulsion powder, 1-3 parts of maifan stone powder, 3-9 parts of graphite and 3-9 parts of silicon carbide crystal grains. Compared with the prior art, the flexible putty powder disclosed by the invention has extremely high water resistance, after the flexible putty powder is exposed to water and affected with damp, the phenomena of hollowing, peeling, cracking and shedding are not generated, the phenomena of becoming yellow, becoming mildewed and generating black spots are not generated, and the flexible putty powder is good in artistic properties, safe, environment-friendly and long in service life.

Description

technical field [0001] The invention relates to building filling materials, in particular to a flexible putty powder. Background technique [0002] Putty is a kind of surface filling material for pretreatment of the construction surface before the construction of paint. Good bonding strength and water resistance to ensure that under the long-term erosion of water vapor in the air, there will be no hollowing, peeling, cracking, etc., and it can still be tightly combined with the substrate, playing a good role in decoration and protection. Since the inner wall of the building is in contact with the human body for a long time and has a great impact on human health, construction projects have put forward higher requirements for the water resistance, aesthetics, safety, and environmental protection of the putty on the inner wall. [0003] Among the existing interior wall putty powders, some have low bonding strength and poor adhesion, some have poor water resistance, are prone t...
