Waterproof paint for outer wall

Abstract

The invention provides waterproof paint for an outer wall. The waterproof paint comprises, by weight, 0.2-0.3 part of thixotropic agent, 0.05-0.1 part of medium pigment, 0.5-1.0 part of medium yellow, 0.01-0.05 part of phthalocyanine blue, 35-45 parts of emulsion, 8-10 parts of quartz powder, 4-6 parts of barium sulfate, 5-6 parts of talcum powder, 1-3 parts of dispersing agent, 2-3 parts of wetting agent, 8-12 parts of alcohol ester, 1-2 parts of coalescing agent, 1-3 parts of thickener, 2-4 parts of modifier, 20-23 parts of deionized water, 80-90 parts of acrylic resin, 1-3 parts of ethylene glycol, 40-50 parts of phthalic anhydride, 3-5 parts of rosin phenolic resin, 20-30 parts of vegetable oil, 5-10 parts of high chlorinated polyethylene resin and 2-4 parts of diluent. The waterproof paint has the advantages that the high molecular materials in the emulsion of the waterproof paint is good in permeability and binding property and high in tensile property, and the problems of cracking and damaging can be solved effectively.

Description

technical field [0001] The invention relates to a paint coating for exterior strong surfaces, in particular to a waterproof paint for exterior walls. 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] In order to solve the above problems, the present invention provides a...

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, so building leakage is caused, which brings great trouble to the construction unit and brings safety hazards to the lives of the people.
