Novel waterproof paint

Abstract

The invention discloses novel waterproof paint and belongs to the field of building materials. The paint is prepared from the following raw materials in parts by weight: 3.5 to 8 parts of organic silicon modified acrylic latex, 1.2 to 2.4 parts of alumina-carbon based refractory brick powder, 1.3 to 3.7 parts of polypropylene wax emulsion, 0.8 to 2.2 parts of sodium polycarboxylate, 1.2 to 3 parts of isotridecyloxy propylamine, 1.3 to 3.4 parts of octadecanoly polyoxyethylene ether, 2.3 to 3.5 parts of fluoroolefin resin and 1.3 to 2.6 parts of dihydroquinoline. Compared with existing waterproof paint, the novel waterproof paint has the advantages of easiness of construction, flat and smooth surface of a coating film, uneasiness of sticking dust, no toxin and no foreign flavor, greenness and environment protection and prominent waterproof effect. The problems that the coating film has poor flexibility, does not resist low temperature and has poor waterproof and moisture-proof performances are solved.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a novel waterproof coating. Background technique [0002] The role of paint is to decorate and protect, protect the surface of the coated object, prevent the erosion of light, oxygen, chemical substances, solvents, etc. from the outside, improve the service life of the coated object, and change the color, pattern, Gloss, texture, etc., improve the aesthetic value of objects. There are various classification methods of architectural coatings, such as interior and exterior wall, floor and ceiling coatings according to the use environment; organic, inorganic and organic-inorganic composite coatings according to the main film-forming substances; water-soluble, emulsion and organic-inorganic composite coatings according to the state of the main film-forming substances Solvent-based powder type; according to the decorative function, it can be divided into flat wall shape, sand wall s...

AI Technical Summary

Problems solved by technology

However, the existing transparent waterproof coatings for external walls that are common on the market have uneven product quality, and they still have a good transparent waterproof effect in a short period of time after coating

However, as time goes by, conventional paints will appear whitening, yellowing, and spit alkali, and the paint film will lose its transparent effect at all, which is equivalent to coating the outer wall with a covering film, which completely covers the original wall of the outer wall. The color of the base surface seriously affects the decorative aesthetics of the exterior wall

Moreover, most of these paints will also produce blisters as the use time increases, making the surface of the paint film uneven, affecting the smoothness of the paint film, and then accumulating dust, resulting in worsening overall appearance.
