Abstract

The invention discloses an interior wall coating coil and a preparation method thereof. The interior wall coating coil comprises the following components in part by weight: 60 to 70 parts of inorganic powder, 10 to 20 parts of white pigment, 1 to 2 parts of dispersant, 1 to 2 parts of lubrication aid, 1 to 3 parts of stabilizer, 0.5 to 1 part of grafting agent and 8 to 12 parts of macromolecular polymer. The interior wall coating coil which has high air permeability, water resistance and flame retardance is prepared by utilizing mechano-chemical modification and stretch thermoforming of polymeric materials, and uniformly dispersing a large amount of inorganic powder and white pigment into a small amount of polymeric material. The interior wall coating coil has white and bright color, is odorless and convenient to use, and can be directly pasted on a mortar layer or a putty layer of an interior wall of a house. The interior wall coating coil avoids the pollution of various kinds of volatile matter generated in the production, construction and use of the traditional brushable interior wall coating, meets the national industrial policy of low cost, environment friendliness and energy conservation, has remarkable economic and social benefits, and is easy to popularize and use widely.

Description

technical field [0001] The invention relates to an interior wall paint coil, more specifically a coil with coating function, which can replace the existing brushable common interior wall paint, and further relates to a preparation method of the interior wall paint coil . Background technique [0002] Brushing interior wall paint (including latex paint) has become an indispensable basic building material for house decoration. With the continuous expansion of new buildings and the transformation of old buildings, the demand for interior wall coatings is increasing. Although the technology of interior wall coatings is very mature, due to the characteristics of coatings that are painted on site, the film-forming substances can only form a film after being painted. Therefore, the paint contains a large amount of film-forming substances, has a strong smell, and even contains formaldehyde, etc. Toxic substances have seriously affected the health and comfort of paint production wo...
