Embodiment 1

[0037] Measure 40 weights of deionized water into the liquid material mixing tank, turn on the disperser of the mixing tank, keep the speed at 200r / min, add 6 weights of dispersant, 8 weights of defoaming agent, and stir for 3 minutes. Add 480 weights of styrene-acrylic emulsion and 5 weights of flocculant in sequence, stir at 300r / min for 5 minutes, then slowly add 100 weights of mica powder, 350 weights of precipitated barium sulfate, and 20 weights of drying agent, and stir at 800r / min for 20 Minutes, and finally slowly add 2 weights of thickener and 2 weights of preservatives successively, and stir at 600r / min for 8 minutes. Reduce the rotational speed to 200r / min and stir for 4 minutes to obtain a polymer emulsion architectural waterproof coating after mechanical defoaming.

Embodiment 2

[0039] Measure 40 weights of deionized water into the liquid material mixing tank, turn on the disperser of the mixing tank, keep the speed at 200r / min, add 6 weights of dispersant, 8 weights of defoaming agent, and stir for 3 minutes. Add 480 weights of styrene-acrylic emulsion and 8 weights of flocculant in sequence, stir at 300r / min for 5 minutes, then slowly add 100 weights of mica powder, 350 weights of precipitated barium sulfate, and 20 weights of drying agent, and stir at 800r / min for 20 Minutes, and finally slowly add 2 weights of thickener and 2 weights of preservatives successively, and stir at 600r / min for 8 minutes. Reduce the rotational speed to 200r / min and stir for 4 minutes to obtain a polymer emulsion architectural waterproof coating after mechanical defoaming.

Embodiment 3

[0041] Measure 40 weights of deionized water into the liquid material mixing tank, turn on the disperser of the mixing tank, keep the speed at 200r / min, add 6 weights of dispersant, 8 weights of defoaming agent, and stir for 3 minutes. Add 480 weights of styrene-acrylic emulsion and 5 weights of flocculant in sequence, stir at 300r / min for 5 minutes, then slowly add 100 weights of mica powder, 350 weights of precipitated barium sulfate, and 25 weights of drying agent, and stir at 800r / min for 20 Minutes, and finally slowly add 2 weights of thickener and 2 weights of preservatives successively, and stir at 600r / min for 8 minutes. Reduce the rotational speed to 200r / min and stir for 4 minutes to obtain a polymer emulsion architectural waterproof coating after mechanical defoaming.

Abstract

The invention discloses a polymer emulsion building waterproof coating and a preparation method thereof. The polymer emulsion building waterproof paint comprises: styrene-acrylic emulsion, dispersant, defoamer, water, flocculant, thickener, drying accelerator, powder, and preservative. The present invention utilizes the low glass transition temperature emulsion, and the polymer emulsion architectural waterproof coating prepared in combination with flocculants and drying accelerators solves the problem that such products cannot be constructed at low temperatures, and reduces the ambient temperature that can be constructed from the current 6°C to 1°C. °C; The polymer emulsion architectural waterproof coating of the present invention does not need to add film-forming agents and plasticizers, and the finally formed waterproof film has stable and long-lasting properties, and there will be no film-forming late stage caused by volatilization and migration of film-forming aids and plasticizers. The problem of performance degradation of the waterproof membrane; the invention is simple to manufacture, low in cost, environmentally friendly and pollution-free, can be mass-produced and applied, and has practicability.

Description

technical field [0001] The invention belongs to the field of waterproof coatings, and more specifically relates to a polymer emulsion architectural waterproof coating and a preparation method thereof. Background technique [0002] Polymer emulsion architectural waterproof coating is a one-component water-emulsion waterproof coating made of polymer emulsion as the main raw material and adding other additives. Due to the high elongation of the coating film, it has good cracking resistance of the base layer. Ready-to-use, convenient construction, generally used in building waterproofing projects in non-long-term immersion environments, generally called acrylic waterproof coatings on the market, the implementation standard of this type of product is JC / T 864-2008 "Polymer Emulsion Building Waterproof Coatings" Type I standard. Chinese invention patent CN201610012228.1 discloses the method of using acrylic acid emulsion and barium sulfate as the main raw materials and adding ben...
