Abstract

The invention relates to a clean-odour alkyd paint and a preparation method thereof. The paint comprises the following components in parts by weight: 40-75 parts of super-benzene-removing high-performance resin, 0.3-0.6 parts of drier, and 0.1 parts of anti-skinning additive ~0.3 parts, 0.1~0.4 parts of flavoring agent, 7~25 parts of solvent, optional, 0~30 parts of pigment, optional, 0~0.5 parts of dispersant, optional, 0~0.05 parts of leveling agent . The odor-free alkyd paint of the present invention adopts a healthy solvent that is harmless to the human body, so that the produced alkyd resin is completely free from harmful substances such as benzene, which greatly improves the health and safety of the product; it can give people fresh and comfortable during use Even sensitive people can breathe freely, giving people all-round enjoyment.

Description

technical field [0001] The invention relates to coatings, in particular to a clean-tasting alkyd coating and a preparation method thereof. Background technique [0002] With the continuous improvement of people's awareness of environmental protection, the concept of green decoration has attracted more and more attention. Alkyd products still occupy a very important share in the home improvement market where water-based paints are popular due to their irreplaceable advantages of full paint film, bright colors, convenient construction, high gloss, and excellent mechanical properties. [0003] Although the traditional environmentally friendly alkyd paint has a good potential for environmental protection, in the traditional alkyd resin synthesis process, xylene solvents must be used, and metal soap driers and pigments must be used when making paint films. If the additives and pigments are not controlled, they will contain heavy metal salts that are harmful to the human body, su...
