AI Technical Summary

Problems solved by technology

[0004] Existing polymer cement-based waterproof coatings have defects such as long drying time, slow curing, low tensile strength after film formation, and low bond strength of the base layer. Therefore, it is necessary to study an environmentally friendly waterproof coating that can dry quickly and have high film-forming mechanical strength.

Abstract

The invention belongs to the technical field of environment-friendly coating materials, and relates to an environment-friendly waterproof coating material and a preparation method thereof. The environment-friendly waterproof coating material is prepared from the following raw materials in parts by weight: 40-50 parts of an acrylic resin, 30-40 parts of an epoxy resin, 20-30 parts of polyether polyol, 15-25 parts of polyvinyl alcohol, 10-20 parts of a filler, 5-8 parts of a water-soluble adhesive, 4-6 parts of carbon fiber, 3-8 parts of an auxiliary agent, 3-5 parts of nano silicon dioxide, 3-5parts of calcium oxide and 1-3 parts of a drying agent, wherein the drying agent is prepared from the following raw materials in parts by weight: 30 to 40 parts of propylene glycol diacetate, 20 to 30 parts of a polybutenoic acid ester polymer, 10 to 15 parts of microcrystalline cellulose and 3 to 5 parts of cerous sulfate. The waterproof coating material disclosed by the invention is non-toxic,odorless, environmentally-friendly and safe, has good elasticity, impact resistance, wear resistance, flexibility and waterproofness, and can be quickly cured into a film so as to substantially shorten the drying and curing time, so that the next procedure can be quickly implemented, and the construction efficiency is remarkably improved.

Description

technical field [0001] The invention belongs to the technical field of environmental protection coatings, and relates to an environmental protection waterproof coating and a preparation method thereof. Background technique [0002] Paint is a liquid or fixed material that forms a thin film on the surface of the object to be protected or decorated to protect, decorate and specific functions. With the development of the economy, paint is used in industry and agriculture, national defense, scientific research and people It has been widely used in daily life. With the development of industry, the variety of coatings is increasing, and the quality and performance are constantly improving. People's functional requirements for coatings are also getting higher and higher. Coating will be the market demand trend in the future. The waterproof film formed after curing of waterproof coating has certain extensibility, elastic-plasticity, crack resistance, impermeability and weather resi...
