High-solid terrace coating, preparation method and application thereof

Abstract

The invention discloses a high-solid terrace coating, a preparation method and application thereof. The coating is prepared from the following raw materials in percentage by weight: 50 to 55 percent of organosilicone modified epoxy resin; 15 to 30 percent of aliphatic amino resin, 4 to 10 percent of plasticizer, 5 to 10 percent of TiO2, 5 to 15 percent of pigment and filler, 4 to 5 percent of reactive diluent, 0.5 to 1.0 percent of defoaming agent, 0.5 to 1.0 percent of dispersant, and 0.2 to 0.5 percent of flatting agent 354. Experimental research shows that the high-solid terrace coating has good corrosion-resistant properties such as acid resistance and alkaline resistance as well as stronger toughness and mechanical property, no volatile solvent exists and the pigment and filler have small consumption in the raw materials of the high-solid terrace coating, and the high-solid terrace coating is an environment-friendly, nontoxic and good terrace coating. The preparation method of the coating has strong maneuverability, high production efficiency and low energy consumption, ensures that finished products obtained through the preparation have high qualification rate, and can realize industrialized large scale production.

Description

technical field [0001] The invention relates to a coating, in particular to a high-solid floor coating, a preparation method thereof and an application thereof in preparing a ground anti-corrosion coating. Background technique [0002] Floor coatings in the prior art have the characteristics of high hardness and stain resistance. Generally, reactive resins are selected as film materials. The most common application is solvent-based epoxy floor coatings. However, due to the difference in film-forming substances, The properties of the obtained coatings are also different. For example, epoxy coatings have good adhesion to polar substrates and high toughness. The disadvantages are poor weather resistance and poor low-temperature curing performance; polyurethane coatings have excellent mechanical properties and toughness. The curing temperature range is wide, but when the reaction is incomplete, it will contain toxic free isocyanate, which will seriously pollute the environment a...

Problems solved by technology

[0004] ①Solvent-based epoxy floor coatings have certain toxicity, and after volatilization, they will cause greater environmental pollution and greater harm to human life and health;

[0005] ② Due to the large content of volatile organic compounds (VOC) in solvent-based coatings, the volatilization of solvents during the curing and film formation process will cause capillary pores in the coating film layer, which greatly reduces the anti-corrosion performance, toughness and mechanical properties of the coating film.
