Waterproof paint

Abstract

Disclosed waterproof paint is prepared from the following raw materials in parts by weight: 35-45 parts of an emulsion, 8-10 parts of quartz powder, 4-6 parts of barium sulfate, 5-6 parts of talcum powder, 1-3 parts of a dispersant, 2-3 parts of a wetting agent, 8-12 parts of an alcohol ester, 1-2 parts of a film-forming auxiliary agent, 1-3 parts of a thickening agent, 2-4 parts of a conditioning agent, 20-23 parts of deionized water, 80-90 parts of acrylic resin, 1-3 parts of glycol, 40-50 parts of phthalic anhydride, 3-5 parts of rosin phenolic resin, 20-30 parts of plant oil, 5-10 parts of high chlorinated polyethylene resin and 2-4 parts of a diluents. The provided waterproof paint is good in water resistance, long in service life, green, environment-friendly and free of generation of toxic and harmful substances.

Description

technical field [0001] The invention relates to the technical field of building wall materials, in particular to a waterproof paint. Background technique [0002] Traditional roof waterproofing will cause concrete to dry and crack under the sun. There are often obvious oblique cracks at the corners of reinforced concrete slabs or obvious transverse cracks in the central part. Once cracking occurs, it is often affected by temperature changes, drying shrinkage and wet expansion, etc., so that the cracks gradually expand, coupled with factors such as uneven settlement of the foundation or earthquakes, the degree of cracking is more obvious, and some engineering cracks have a width of more than 5 mm. Also a lot, therefore cause building leakage, bring very big trouble to the construction unit, bring the hidden danger on the safety of common people's life. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the technical problem to be solved by the ...

Problems solved by technology

Once cracking occurs, it is often affected by temperature changes, drying shrinkage and wet expansion, etc., so that the cracks gradually expand, coupled with factors such as uneven settlement of the foundation or earthquakes, the degree of cracking is more obvious, and some engineering cracks have a width of more than 5 mm. There are also many, thus causing building leakage, bringing great trouble to the construction unit, and bringing safety hazards to the lives of the people.
