Abstract

The invention relates to safe and environment-friendly semi-matte varnish for an automobile interior trim part and a preparation method thereof. The varnish comprises the following ingredients in parts by weight: 200 to 300 parts of a precursor solution A and 80 to 120 parts of a precursor solution B, wherein the precursor solution A comprises the following ingredients in parts by weight: 15 to 25 parts of a mixed solvent A, 40 to 45 parts of acrylic resin A, 20 to 25 parts of acrylic resin B, 0.3 to 0.6 part of dispersing agents, 1.5 to 2.0 parts of anti-settling agents, 3 to 5 parts of extinction powder, 0.3 to 0.6 part of orientation agents, 4 to 8 parts of wear-resistant agents, 1.0 to 1.5 parts of ultraviolet light absorbers, 0.3 to 0.6 part of flatting agents and 1 to 3 parts of drier; the precursor solution B comprises the following ingredients in parts by weight: 45 to 55 parts of curing agents and 45 to 55 parts of a solvent B. During the preparation, mixing, stirring and grinding are performed to obtain the precursor solution A; then, the precursor solution B is prepared through mixing and stirring; then, the precursor solution A and the precursor solution B are mixed. Compared with the prior art, the safe and environment-friendly semi-matte varnish has the advantages that the scratch resistance, wear resistance and chemical corrosion resistance are realized; the luster is stable; the comfort durability and decoration attractive appearance are realized; safety and environment-friendly effects are realized; the production and the use are easy.

Description

technical field [0001] The invention belongs to the technical field of safe and environmentally friendly pigments and dyes, and relates to a safe and environmentally friendly semi-matte varnish for automotive interior parts and a preparation method thereof. Background technique [0002] With the development of the times, cars play an increasingly important role in people's daily life, as if they have become people's second home, so people's requirements for cars are getting higher and higher, especially for automotive interior parts. In terms of coatings, in addition to the traditional decorative aesthetic requirements, it must also be comfortable and durable, which can not only help people relieve fatigue, improve the comfort of use, but also prolong the service life of interior parts. [0003] However, the existing interior paints are difficult to take into account both decorative aesthetics and comfort and durability. Therefore, it has become one of the technical problem...
