Green and environment-friendly interior wall putty powder and preparation method thereof

Abstract

The invention discloses green and environment-friendly interior wall putty powder. The green and environment-friendly interior wall putty powder is prepared from the following components in parts by weight: 50-60 parts of heavy calcium carbonate powder, 8-16 parts of white volcanic ash, 5-10 parts of attapulgite, 2-3 parts of white graphene nanofibers, 4-7 parts of single amino-terminated polyethylene glycol modified rosin-based hyperbranched polyester, 2-4 parts of rosin-based mono-quaternary ammonium trimethyl silicic acid tetra (1imidazolyl) boric acid composite salt and 0.5-1.5 part of mastic gum. The invention further discloses a preparation method of the green and environment-friendly interior wall putty powder. The green and environment-friendly interior wall putty powder is betterin comprehensive performance, better in environment-friendly performance, mechanical performance and water resistance, better in performance stability, and capable of effectively resisting cracking, peeling and falling off.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a green and environment-friendly interior wall putty powder and a preparation method thereof. Background technique [0002] With the development of society and the improvement of living standards, people's awareness of environmental protection and health is constantly increasing, and their requirements for the comfort and safety of the living environment are getting higher and higher. As a common building interior wall decoration material, the environmental protection and functionality of interior wall putty powder have attracted widespread attention. Interior wall putty is a kind of decorative gel material for leveling the surface of the wall. It is used to fill the gaps in the wall and repair the uneven defects on the painted surface, so that the paint or lacquer can be applied on the wall to form a smooth and smooth surface. Uniform paint film. Its quality directl...

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.
