Embodiment approach

[0061] ① Measure deionized water, 731A dispersant, and 2706 defoamer into the liquid material mixing tank, turn on the disperser in the mixing tank, adjust the speed at 300r / min, and stir for 2 minutes.

[0062] ② Measure SH-60 acrylic emulsion, XR-100 aziridine cross-linking agent and PEG 300 film-forming aid, add it to the liquid material mixing tank, adjust the speed to 500r / min and stir for 15 minutes.

[0063] ③ Add the 665T thickener slowly after metering, and stir at 800r / min for 15 minutes to obtain the liquid material component.

[0064] ④ Measure 52.5 high sulfate-resistant Portland cement, modified mica powder, and 60-120 mesh quartz sand and add them to the weightless powder mixing tank. Turn on the mixer and adjust the speed at 400r / min for 5 minutes.

[0065] ⑤ Measure titanate cross-linking agent microcapsule powder, cellulose ether GMC-1212, calcium formate, CR-818 water reducer and add to the powder mixing tank, adjust the speed to 600r / min for 15 minutes, and...

Abstract

The invention discloses a frost-resistant and acid-resistant polymer cement waterproof coating and a preparation method thereof. A kind of antifreeze and acid-resistant polymer cement waterproof coating, the antifreeze and acid-resistant polymer cement waterproof coating includes liquid material and powder material, wherein: the liquid material includes: acrylic acid emulsion, dispersant, defoamer, aziridine cross-linking agent, film-forming aid, water, thickener; the powder includes: high sulfate-resistant Portland cement, modified mica powder, quartz sand, titanate crosslinking agent microcapsule powder, water reducer, Early strength agent, cellulose ether. The invention has good flexibility and low-temperature bridging crack ability, and the waterproof paint film still has a good application effect under severe cold conditions, and has extremely high acid corrosion resistance.

Description

technical field [0001] The invention belongs to the field of waterproof coatings, and more specifically relates to a frost-resistant and acid-resistant polymer cement waterproof coating and a preparation method thereof. Background technique [0002] Polymer cement waterproof coating, referred to as JS waterproof coating, is made of acrylate, ethylene-vinyl acetate and other polymer emulsions and cement as the main raw materials, and is prepared by adding fillers and other additives. It is cured by water volatilization and cement hydration reaction. Film-forming two-component water-based waterproofing coating. Due to the simple construction, the extensibility and compactness of the polymer coating film, the high strength of the hydraulic cementitious material, and the advantages of being easy to bond with the wet base, the ratio of polymer emulsion to cement can be adjusted to meet different engineering environments. In recent years It is widely used in water-based waterproo...
