Problems solved by technology

[0003] The traditional interior wall putty powder for interior decoration uses polyvinyl formal glue or modified polyvinyl formal glue as the adhesive, and most of them contain harmful substances such as formaldehyde, which can cause damage to the human nervous system, and in severe cases can Poisoning and carcinogenic, especially harmful to infants and young children
In addition, the interior wall putty powder on the market also generally has defects such as low strength, poor water resistance, easy cracking, peeling, peeling, and mildew on the coating.
[0004] The Chinese invention patent with application number 03117999.1 discloses an environmentally friendly gypsum-based building putty powder, which belongs to building materials. The problem of large pollution, the technical solution of this invention is to use building gypsum as the main setting and hardening component, and solve the problem of fast setting and hardening of building gypsum and large loss of strength of a single retarder through a composite retarder. Ether compound, reduce material cost, improve the water retention of putty, use water-soluble rubber powder to improve the bonding strength of construction putty, this environmentally friendly gypsum-based construction putty powder is a single-component solid powder, does not contain toxic substances, and has good construction performance , short construction period, high bonding strength, fine and smooth putty surface, can be used as putty for building interior walls
However, the above-mentioned putty powder still has disadvantages such as poor stability, strength and hardness not meeting specific construction requirements, etc.
