preparation example Construction

[0094] 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 weather-proof terrace paint as well as a preparation method thereof. The weather-proof terrace paint consists of components A and B, wherein the component A comprises the components in percentage by weight as follows: 1-30% of PUA (Polyurethane Acrylate) resin, 25-50% of hard monomer, 2-40% of soft monomer, 0.1-5% of a photosensitizer, 0% or 0.1-2% of an accelerator, 0.1-2% of a flatting agent and 0.1-2% of a deformer. The component B comprises the components in percentage by weight as follows: 1-25% of PUA resin, 5-40% of hard monomer, 2-30% of soft monomer, 2-30% of wear-resisting stuffing and 0.1-5% of a general initiator. When the paint is used, the mass proportion of the components A and B is 1:(0.8-1.5). The weather-proof terrace paint provided by the invention can be adapted for coating outdoor weather-proof and wear-resisting terraces with higher load demand, and meanwhile the coating film is extremely excellent in wear-proofness, chemical resistance and low temperature bending performance.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a weather-resistant 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 epoxy resin product...
