Problems solved by technology

my country's industrial floor coatings are basically solvent-based and solvent-free epoxy floor coatings at present. Solvent-based epoxy floor coatings contain more organic solvents. These organic solvents are discharged into the atmosphere during the production and construction stages of coatings, polluting The environment, while endangering human health; solvent-free epoxy floor coatings contain a small amount of reactive diluents, commonly used reactive diluents are butyl glycidyl ether (with certain toxicity), self-leveling construction method, coating film thickness of 1 ~5mm, high cost and contains a small amount of volatile organic solvents

preparation example Construction

[0071] Various high-speed mixers are required in the preparation process of the paint, and spraying, flow coating and other methods are used for painting. In these processes, the paint will generate foam. The air in the foam will not only hinder the dispersion of pigments and fillers, but also make the utilization rate of the equipment insufficient and affect the output. The air bubbles generated during construction will cause surface defects of the paint film, which will not only damage the appearance, but also affect the corrosion resistance and weather resistance of the paint film. . Therefore, in order to prevent foaming during use, a defoamer should be added to the paint. The defoamer should have the following characteristics: 1. The surface tension of the defoamer should be smaller than that of the liquid to be defoamed; 2. The solubility in the liquid that needs to be defoamed should be as small as possible; 3. It should have good dispersibility ; 4. It cannot react wi...

Abstract

The invention provides a floating colored sand self-leveling floor coating and a preparation method thereof. The coating is composed of two components A and B. The component A comprises, by weight, 10to 40 parts of BPA-type epoxy resin, 5 to 30 parts of diluted epoxy resin, 5 to 30 parts of floating colored sand, 0.1-2 parts of a leveling agent and 0.1-2 parts of a defoaming agent. The componentB comprises, by weight, 50 to 100 parts of an alicyclic amine curing agent and 0.1 to 3 parts of an accelerator. In use, a mass ratio of the component A to the component B is 6 to 6.5: 1. The floatingcolored sand self-leveling floor coating is suitable for floor coating having high requirements on decoration, compressive resistance, abrasion resistance and load. The coating film has excellent compressive strength, wear resistance and chemical resistance.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a floating colored sand self-leveling floor coating and a preparation method thereof. Background technique [0002] Floor coatings are a building material that has entered China in recent years. It has gradually been recognized and accepted by the majority of users, and is widely used in civil and industrial buildings and facilities such as hospitals, parking lots, sports fields, and pharmaceutical factory workshops. [0003] According to the classification of film-forming substances, floor coatings can be divided into inorganic, polyurethane, polyurea, acrylic, epoxy and other types. Among them, epoxy flooring is the most widely used, accounting for about 50% of the market share. [0004] Epoxy resin materials have excellent bonding strength to the surface of metal and non-metal materials, good dielectric properties, small shrinkage, good dimensional stability, and high hardness. Many e...
