Fast-dry curing coating

Abstract

The invention relates to the technical field of building coatings, in particular to a fast-dry curing coating. The coating comprises a JS waterproof coating and an auxiliary material, wherein the JS waterproof coating comprises a polyacrylate emulsion, an ethylene-vinyl acetate copolymer emulsion and an additive, and the composition of each component is as follows: 30-40 parts of the polyacrylateemulsion, 28-35 parts of the ethylene-vinyl acetate copolymer emulsion, 8-18 parts of the additive, and 12-20 parts of the auxiliary material. The effect of accelerating film formation and dry curingof a waterproof layer of the JS waterproof coating is achieved by improving the ratio composition of the additive and the auxiliary material, a length of time of film formation and a dry curing periodof the waterproof layer of the JS waterproof coating is greatly shortened, and the impact caused by bad weather is effectively reduced or avoided. By adding an antistatic agent, an antioxidant and adefoaming agent in the auxiliary material, the antistatic performance and anti-oxidation performance of the JS waterproof coating are effectively improved, and production of a large amount of air bubbles during the preparation process of the JS waterproof coating to affect the finished-product quality of the JS waterproof coating is avoided.

Description

technical field [0001] The invention relates to the technical field of architectural coatings, in particular to a quick-drying coating. Background technique [0002] JS waterproof coating refers to polymer cement waterproof coating, also known as JS composite waterproof coating. Among them, J refers to the polymer, and S cement ("JS" is the pinyin prefix of "polymer cement"). JS waterproof coating is an organic liquid material composed of polyacrylate emulsion, ethylene-vinyl acetate copolymer emulsion and other polymer emulsions and various additives. [0003] The construction of the JS waterproof coating protective layer or decorative layer must be carried out 3-4 days after the waterproof layer is completed, and the blocks (such as floors, tiles, mosaics, etc.) are pasted.

[0003] The construction of the JS waterproof coating protective layer or decorative layer must be carried out 3-4 days after the waterproof layer is completed, and the blocks (such as floors, tiles, mosaics, etc.) are pasted. However, changes in the environment during construction will affect the film formation and drying of the waterproof layer. , such as rain and snow during the drying and curing period after construction will greatly increase the duration of the drying and curing period, thereby delaying the construction period
