Environmental paint
close National Standard for Environmental Paints (GB 5206.1) In this term, coating is defined as a general term for a class of liquid or solid materials that can form a solid coating film with protective, decorative or special properties (such as insulation, anti-corrosion, signs, etc.) on the surface of an object. In the early days, vegetable oil was the main raw material, so it was called paint. Now synthetic resin has largely or completely replaced vegetable oil, so it is called paint. For the above definition, 3A environmental protection paint has the following two points of view: 1. The reason why this kind of material is called paint rather than paint is more due to the development of paint varieties and categories, because the name of paint can no longer cover all kinds of existing products in the industry, and the word "paint" can cover all kinds of products in the industry. The use of paint names is more accurate and scientific. For example, the name of paint is not suitable for powder coating products. Paint and paint are not interchangeable here. Therefore, the coating can cover solid powder coating and liquid paint, but the replacement is not feasible, so the explanation in the standard is not in place. 2. The "note" in the coating terminology in the standard: "the word" paint "can be used in the name of specific coating varieties, such as ready mixed paint, thick paint, etc." is also somewhat inappropriate. In fact, the word "paint" is not only used in specific paint varieties, but also in a large number of paint categories, such as acrylic paint, polyurethane paint, etc., as well as in general terms of application fields, such as anti-corrosion paint, automotive paint, marine paint, etc. In fact, except for individual cases, the terms "paint" and "paint" are universal, and they do not refer to specific varieties.
