Abstract

The invention relates to the technical field of paint, in particular to environment-friendly interior wall paint and a preparation method thereof. The environment-friendly interior wall paint is prepared from the following raw materials in parts by weight: 30 to 60 parts of acrylic emulsion, 20 to 40 parts of polyurethane emulsion, 15 to 40 parts of filler, 10 to 30 parts of polyhydroxy compound,2 to 10 parts of defoaming agent, 3 to 10 parts of dispersing agent, 0 to 10 parts of other auxiliary agents and 100 to 150 parts of water. The environment-friendly interior wall paint is excellent inenvironmental protection performance, good in constructability, good in leveling property, excellent in scrubbing resistance, smooth in paint film, suitable for surface coating of different materialssuch as indoor wall surfaces, ceilings, brick structures and asbestos boards, good in covering power, high in coating rate, high in adhesive force and capable of effectively preventing cracking; meanwhile, the scrubbing frequency is high, the waterproof performance is good, the paint can be sprayed on a concrete wall surface and a metal pipeline for a long time, and no pungent smell exists duringspraying.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to an environment-friendly interior wall paint and a preparation method thereof. Background technique [0002] Interior wall paint refers to the paint painted on the interior wall, which can be mainly divided into water-soluble paint and latex paint. 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 acrylic copolymer emulsion as diluent. It is a paint that is easy to construct, safe, resistant to washing with acrylic copolymer emulsion, and has good air permeability. It can be formulated according to different color schemes to produce different colors. Acrylic copolymer emulsion interior wall paint, oil-based interior wall paint, and dry powder interior wall paint are acrylic copolymer emulsion pai...
