Abstract

The invention discloses a novel water resistant interior wall coating for a building. The novel water resistant interior wall coating for the building is prepared from the following raw materials in parts by weight: 100 parts of sweet potato powder, 20-30 parts of formaldehyde, 10-20 parts of sodium hydroxide, 15-25 parts of sodium hexametaphosphate, 30-40 parts of sulfuric acid, 35-45 parts of tributyl phosphate, 70-80 parts of water, 10-20 parts of ethanol, 20-40 parts of a color pigment, 25-35 parts of magnesium chloride, 40-50 parts of castor oil, 5-10 parts of tetrahydrofuran, 60-80 parts of a extender pigment, 30-40 parts of barium chloride, 40-60 parts of talc and 20-50 parts of sodium methylene bis-naphthalene sulfonate. According to the novel water resistant interior wall coating for the building disclosed by the invention, the product solid content is 35-40 percent, and the fineness is 40-60 microns; the surface drying time is 0.6-1h, the novel water resistant interior wall coating does not have the phenomena of bubbling and powder removal after being soaked in water for 24h, is brushed without sagging, does not have the phenomena of tackiness and cracking at the temperature of 90 DEG C for 5h, has the viscosity to be 40-60s and the adhesion to be 100 percent, is smooth in appearance of a coating and can be widely produced and used for continuously replacing the traditional materials.

Description

technical field [0001] The application belongs to the field of coatings, in particular to a novel water-resistant interior wall coating for buildings. Background technique [0002] Interior wall paint is latex paint for general decoration. Latex paint is an emulsion paint, which can be divided into two categories: polyvinyl acetate emulsion and acrylic emulsion according to different substrates. Latex paint uses water as the diluent. It is a paint that is easy to construct, safe, washable, and has good air permeability. It can be formulated according to different color schemes to produce different colors. Types: Water-based interior wall paint, oil-based interior wall paint, dry powder type interior wall paint, are water-based paints, mainly composed of water, emulsion, pigments, fillers, and additives. Interior wall coatings include liquid coatings and powder coatings. Common latex paints and wall paints are liquid coatings. The ingredients of interior wall paint are bas...
