Waterproofing agent of Nano coating material

Abstract

A nano-class water-proof paint for internal and external walls and roof of building contains pure acrylate emulsion, filler (rutile-type titanium oxide powder, aluminium silicate, wollastonite and nano calcium), phosphate as emulsifier and disperser, dihydroxy propane as filming agent, polyacrylamide as levelling agent, and penta sodium as bactericide. Its advantages are high rubbing resistance, weatherability, dispersity and glossiness, good hardness and toughness of its film, and better self-cleaning nature.

Description

technical field [0001] The invention relates to a building waterproof material, which is used for waterproof decoration and anti-leakage of the inner and outer walls and roofs of various buildings, in particular to a nano-waterproof coating. Background technique [0002] The traditional petroleum asphalt waterproof material used in the prior art is easy to flow at high temperature and brittle at low temperature. It is prone to flow, crack, rot and leakage, and the waterproof effect is unstable. There are also various asphalt-modified waterproof materials, such as emulsified asphalt, rubber asphalt and tung oil asphalt and other waterproof coatings or waterproof ointment, but the price is high, it needs hot construction and is difficult to promote, and it cannot be used as a decorative coating for interior and exterior walls. Contents of the invention [0003] The purpose of the present invention is to address the deficiencies in ...
