Problems solved by technology

[0004] In addition, the existing coatings need to use a variety of raw materials in the preparation process. In the past, various raw materials were poured into a large tank for stirring, and the components were gradually mixed with the stirring, but this method of stirring and mixing There are still uneven mixing and low efficiency, so that there is color difference after the product leaves the factory

Abstract

The invention belongs to the field of preparation of coatings and particularly relates to an environment-friendly anticorrosive coating and a preparation method thereof. The coating is prepared by mixing an oil paint component and a curing agent component in a weight ratio of 100 to (20-30). The oil paint component is prepared from the following components in percentage by weight: 55-70wt% of acrylic resin, 5-15wt% of tea stem powder, 10-15wt% of organic pigments, 3-5wt% of rosin, 10-15wt% of solvent and 2-5wt% of surfactant. The curing agent component is prepared from the following components in percentage by weight: 60-69wt% of curing agent, 30-39wt% of solvent and 0.05-1wt% of dehydrating agent, wherein the dehydrating agent is one or two of butyl ester, cyclohexanone and butyl cellosolve. The added tea stem powder can react with harmful gases such as formaldehyde and dimethylbenzene to form non-volatile harmless macromolecular chain substances, so as to effectively eliminate harmful gases in the atmosphere, so that the prepared coating is relatively environmentally friendly and pollution-free. Due to the design of a stepwise feeding device, the raw materials are fully and uniformly mixed, thereby improving the performance of the coating. Due to adoption of a discharging spill-proof hopper, the packaging process is simple, convenient and efficient.

Description

technical field [0001] The invention belongs to the field of paint preparation, and in particular relates to an environment-friendly anticorrosion paint and a preparation method thereof. Background technique [0002] Acrylic resin coating is a type of synthetic resin coating with the most comprehensive performance and the strongest versatility. Compared with other polymer resin coatings, acrylic resin coating has many outstanding advantages, such as its excellent light resistance, weather resistance, and corrosion resistance. , has better resistance to acid, alkali, salt, grease, detergent and other chemicals staining and corrosion performance. Acrylic resin coatings are divided into two types: thermosetting and thermoplastic. Most thermosetting products are synthesized at high temperature, which will produce a large amount of toxic organic gases, which is not in line with the slogan of "low carbon and environmental protection" advocated by the international community, and ...
