All-solid environment-friendly protective paint and preparation method thereof

Abstract

The invention relates to all-solid environment-friendly protective paint and a preparation method thereof. The paint is prepared from the following raw materials: 10-40% of all-solid alkyd resin, 5-30% of mineral wax, 20-50% of drying oil, 5-20% of a sulfonate based preservative, 5-15% of calcium carbonate, 1-5% of fatty acid ester, 1-10% of a thickening agent, 5-20% of a petroleum resin, 0.1-0.5% of a drying agent and 0.2-0.5% of an anti-skinning agent. The preparation process for the protective paint comprises the following steps: adding drying oil, mineral wax and petroleum resin into a reaction kettle, rising the temperature to be 100-110 DEG C, stirring at the rotating speed of 10-20 rpm, and stirring at the speed of 30-35 rpm after the mixture is fully molten to uniformly mix the mixture; stopping heating, adding all-solid alkyd resin, fatty acid ester, the sulfonate based preservative, the thickening agent, the drying agent and the anti-skinning agent in sequence under the stirring condition; discharging when the temperature is reduced to be 40 DEG C. Compared with the conventional protective paint, the protective paint provided by the invention has the advantages of being free of solvent, environment-friendly, good in safety and stability, high in preservative efficiency, and the like.

Description

technical field [0001] The invention relates to a preparation and a process method of an all-solid environmental protective paint. Background technique [0002] Rusting (oxidation) is one of the basic chemical characteristics of many metals, and it will slowly occur at room temperature. From a thermodynamic point of view, metal compounds are in a low-energy state, while single metals are in a high-energy state. Corrosion is the spontaneous transformation of unstable metals into their compounds, so it can be said that corrosion is a natural tendency for most metals. [0003] Metals endure five to ten years or more as they are processed into finished products, during which time the environment can be harsh. Especially the steel materials commonly used in automobiles, once rusted, the iron oxide produced will absorb water molecules in the air, causing more serious corrosion. The anti-rust treatment of the car is mainly concentrated on the body. A body during manufacture is c...

Problems solved by technology

The coating does not have the shortcomings of solvent-based coatings, such as the volatilization of organic solvents into the air during the drying and film-forming process, which will cause fires, pollute the environment, and affect human health. It also avoids unstable storage and complicated production processes for water-based coatings. shortcoming
