Problems solved by technology

However, calcium chloride and sodium chloride in its composition will not be lost due to the volatilization of water, but will permanently exist in the formed waterproof film. Calcium chloride and sodium chloride have certain corrosiveness and water absorption. Therefore, it has a bad influence on the water resistance of the membrane layer.

Abstract

The invention discloses a rapidly-hardened waterproof building coating which comprises a component A and a component B, wherein the component A is prepared from the following raw materials in parts by weight: 62-70 parts of silicone acrylic emulsion, 9-12 parts of illite, 10-15 parts of fluorgypsum, 1.5-2 parts of dinonyl naphthalene sulfonic acid, 1.5-2 parts of zinc dialkyl dithiophosphate, 5-6 parts of sodium carboxymethyl starch and 3-4 parts of arabic gum; the component B is prepared from the following raw materials in parts by weight: 0.5-1 part of vanadium acetylacetonate, 0.8-1.2 parts of methyl nadic anhydride, 4-5 parts of barite and 2-3 parts of potassium metasilicate. The rapidly-hardened waterproof building coating disclosed by the invention adopts a composite inorganic mineral substance of the silicone acrylic emulsion, various additives are added for preparing the component A, and the component A is matched with the component B which is prepared from nanometer composite components; experiments prove that the rapidly-hardened waterproof building coating is short in hardening time, easy to construct, also good in waterproofness and physical properties, stable and reliable.

Description

technical field [0001] The invention belongs to the field of building materials, and relates to a building waterproof coating, more specifically, to a quick-setting waterproof building coating and a preparation method thereof. Background technique [0002] Architectural waterproof coating is a viscous liquid polymer synthetic material with no fixed shape at room temperature. After coating, it can form a tough waterproof coating film on the surface of the base layer after the volatilization of solvent or water evaporation or reaction curing. the general term for. Common types of waterproof coatings include polyurethane waterproof coatings, one-component polyurethane waterproof coatings, polymer cement waterproof coatings, polymer emulsion waterproof coatings, asphalt waterproof coatings and modified bitumen waterproof coatings. [0003] Polymer emulsion waterproof coatings have been widely used in construction, and there are mainly two forms: polymer emulsion architectural w...
