Problems solved by technology

Among them, water-emulsion waterproof coatings, such as APP modified asphalt materials, neoprene asphalt, etc., have a single composition structure, and the bonding strength with the cement concrete bridge deck is low. empty phenomenon
Solvent-based waterproof coatings have good adhesion to cement concrete bridge decks, but poor high temperature resistance and corrosion resistance
Reactive waterproof coatings have higher requirements on construction technology and are expensive
Above-mentioned three kinds of waterproof coatings all can not play waterproof performance to concrete bridge deck for a long time, thereby reduced the service life of concrete bridge deck, bring great inconvenience to people

Abstract

The invention discloses high-temperature-resistant and corrosion-resistant waterproof paint. The waterproof paint is prepared from, by weight, 40-65 parts of phenolic resin, 32-46 parts of methyl acrylate emulsion, 23-40 parts of methyl acrylate emulsion, 5-15 parts of n-Octyltrimethoxysilane, 6-18 parts of glycerin, 4-11 parts of calcium sulfate, 3-14 parts of aluminum chloride, 5-10 parts of aluminum oxide, 8-17 parts of talcum powder, 2-8 parts of sodium molybdate, 5-16 parts of short glass fibers, 2-10 parts of polyoxyethylene alcohol ether, 3-7 parts of isophorone diamine, 1-6 parts of diallyl 2,2'-oxydiethyl dicarbonate and 15-30 parts of deionized water. The invention further discloses a preparation method of the high-temperature-resistant and corrosion-resistant waterproof paint. The acid resistance, alkali resistance and salt corrosion resistance of the prepared waterproof paint are good, and the heat-resistance temperature ranges from 205 DEG C to 310 DEG C. The prepared waterproof paint has excellent high temperature resistance and corrosion resistance, and the application range of the waterproof paint can be expanded.

Description

technical field [0001] The invention relates to the field of waterproof materials in the construction field, in particular to a high-temperature-resistant and corrosion-resistant waterproof coating and a preparation method thereof. Background technique [0002] In the waterproofing of concrete bridge decks, it is generally used to paint organic waterproof coatings on the base of buildings to form a protective layer. Among them, the coatings applied can be divided into three types: water-emulsion type, solvent type and reactive type, each of which has its own disadvantages. Among them, water-emulsion waterproof coatings, such as APP modified asphalt materials, neoprene asphalt, etc., have a single composition structure, and the bonding strength with the cement concrete bridge deck is low. empty phenomenon. Solvent-based waterproof coatings have good adhesion to cement concrete bridge decks, but their high temperature resistance and corrosion resistance are poor. Reactive w...
