specific Embodiment

[0083] Specific examples are as follows:

[0084] Table 1

[0085]

[0086]

[0087] The preparation method of above-mentioned one-component water-based waterproof paint comprises:

[0088] ① Measure deionized water, Mingling 730 hydrophobic agent, water-based wear-resistant additive and Yuhong CR-P100 into the liquid material mixing tank, turn on the disperser of the mixing tank, adjust the speed at 300r / min, and stir for 2 minutes .

[0089] ② Measure WACKER 7070 emulsion, DINCH plasticizer, self-crosslinking PVAE solution and raw tung oil into the liquid material mixing tank, adjust the speed to 500r / min and stir for 10 minutes.

[0090] ③Measure Mingling A203E defoamer and sodium hydroxymethyl cellulose solution NC-60 thickener and pre-mix evenly, slowly add to the liquid material mixing tank, and stir at 500r / min for 2 minutes.

[0091] ④ After measuring Hantai Chemical 1130 thickener, Dow RM-8W thickener, and Thor MBS preservative, slowly add it to the liquid ma...

Abstract

The invention belongs to the field of waterproof materials, and particularly relates to a single-component water-based waterproof coating and a preparation method thereof. The coating is prepared from the following raw materials: VAE emulsion, an environment-friendly plasticizer, a self-crosslinking PVA solution, tung oil, a water repellent agent, a water-based wear-resistant additive, polycarboxylic acid mother liquor, water, a defoaming agent, a carboxymethyl cellulose sodium solution, an associated alkali swelling thickener, an associated polyurethane thickener and a preservative. The high-performance VAE emulsion is used as a main film forming substance, the environment-friendly plasticizer and a small amount of tung oil are added, and the prepared single-component water-based waterproof coating is convenient to store and transport, capable of being mixed with pure cement for use on a construction site, free of formaldehyde, odorless, good in environment friendliness and high in paint film elasticity. A self-crosslinked PVA solution is prepared, and the water-based wear-resistant auxiliary agent is added so that the thixotropy, the binding power and the wear resistance of the coating are improved, and the coating can be used for external wall construction. Sodium hydroxyethyl cellulose is dissolved in a mineral oil defoaming agent, so that the problem of easy agglomeration in addition is solved. By adding polycarboxylic acid mother liquor, the openness of the coating is prolonged.

Description

technical field [0001] The invention belongs to the field of waterproof materials, and more specifically relates to a single-component water-based waterproof coating and a preparation method thereof. Background technique [0002] (1) Technical background [0003] Waterproof material is one of the important components of building construction materials. According to the material, it can be divided into asphalt waterproof material, rubber plastic waterproof material, cement waterproof material and metal waterproof material. With the improvement of modern building requirements, modern waterproof material selection and construction technology are becoming more and more standardized, and water-based cement-based waterproof coatings represented by polymer cement waterproof coatings are simple in construction and good in environmental protection. The ratio of cement to meet different engineering environments, has been widely used in waterproof materials in recent years. [0004] ...
