Embodiment 1

[0045] This embodiment provides an anti-aging polymer cement waterproof coating and a preparation method thereof.

[0046] Liquid material: add 140 parts by weight of deionized water to the liquid material stirring tank, open the disperser of the stirring tank, keep the rotating speed at 1000 rpm, then mix 800 parts by weight of ethylene-vinyl acetate emulsion, 60 weight parts Parts of diisononyl cyclohexane 1,2-dicarboxylate were respectively metered and added to the liquid material stirring cylinder to disperse for 10 minutes, then the stirring speed was reduced to 800 rpm, and then 2 parts by weight of dispersant, 3 parts by weight of defoamer and 2 parts by weight of bactericide are added into the liquid material mixing tank after metering, and the liquid material can be packaged after stirring for 20 minutes.

[0047] Powder: Turn on the weightless powder mixer, keep the rotation speed at 600 rpm, then add 300 parts by weight of white cement to the powder mixing tank afte...

Abstract

The invention discloses that the invention belongs to the field of waterproof coatings, and in particular relates to an anti-aging polymer cement waterproof coating and a preparation method thereof. The polymer cement waterproof coating includes liquid material and powder material; the liquid material includes ethylene-vinyl acetate emulsion, diisononyl cyclohexane 1,2-diformate, defoamer, dispersant, bactericide, water , the powder material includes white cement, heavy calcium, titanium dioxide, 2,2,4-trimethyl-1,2-dihydroquinoline polymer, bissalicylic acid bisphenol A, and water reducing agent. The present invention can form a stable and durable waterproof membrane. The waterproof film finally formed by the invention has stable and long-lasting performance, does not have the problem that the performance of the waterproof film is reduced due to the volatilization and migration of the plasticizer after the film is formed, has excellent anti-aging properties, and has a simple manufacturing method, low cost, environmental protection and no pollution. , Can be mass-produced and applied, with practicality.

Description

technical field [0001] The invention belongs to the field of waterproof coatings, and more particularly relates to an anti-aging polymer cement waterproof coating and a preparation method thereof. Background technique [0002] The polymer cement waterproof coating is made of polymer emulsion and cement as the main raw materials, added with fillers and other additives, and is a two-component water-based waterproof coating that is cured into a film by water volatilization and cement hydration reaction, referred to as JS waterproof coating. Because JS waterproof coating can be directly applied on wet or dry base layers, has good adhesion with mortar and concrete, and has good impermeability, it has been widely used in building waterproofing projects in recent years. The executive standard for this type of product is GB / T23445-2009 "Polymer Cement Waterproof Coating". Chinese invention patent application CN201610767968.6 uses ethylene-vinyl acetate emulsion and mixes with plast...
