Plastic coating with lotus leaf effect and preparation method and application thereof

Abstract

The invention discloses a plastic coating with lotus leaf effect and a preparation method and application thereof. The raw material formula of the plastic coating comprises the following components in percentage by mass: 3 to 5 percent of acrylic resin, 12 to 18 percent of organic silicon water repellent, 0.3 to 1 percent of flatting agent, 10 to 12 percent of isopropanol, 10 to 20 percent of diacetone alcohol, 12 to 16 percent of propylene glycol methyl ether acetate, 9 to 16 percent of acetone, 8 to 13 percent of butanone and 11 to 15 percent of butyl acetate. The film of the plastic coating with lotus leaf effect is integrally hydrophobic, water drops roll freely on the film, and residue and tailing are not caused; and the film has good integral hydrophobic property, strong enough adhesive force on plastic and good stability, and can be used on a plastic base material such as an acrylonitrile butadiene styrene (ABS) plastic material or a high impact polystyrene (HIPS) plastic material or the like.

Description

technical field [0001] The invention relates to the technical field of plastic coatings, in particular to a plastic coating with lotus leaf effect and its preparation method and application. Background technique [0002] With the development of the paint industry, the performance requirements of the paint film are getting higher and higher, and the antifouling ability of the paint film is a new assessment index. As a toy industry, the high hydrophobicity of the paint film can improve its antifouling performance on the one hand, and increase ornamental and fun on the other hand, meeting the needs of the majority of toy customers. [0003] At present, there have been researches on introducing silicone water repellent into plastic coatings to improve the antifouling performance of the paint film, but the finished product cannot take into account the two performance indicators of adhesion and water repellency: if the adhesion of the paint film is high, the paint film’s Hydropho...

Problems solved by technology

[0007] When the PVC value of the plastic coating formula is lower than CPVC, the base material not only completely wraps all the pigments and fillers, but also fills up all the gaps with the excess base material; the protective function of the plastic coating comes from the formation of clogged pores. Similar to the coating of plastic film, this kind of coating can well reduce the absorption of external liquid water, but it also hinders the escape of water vapor from the substrate; since the paint film does not have the function of breathing, the water vapor of the substrate is easy to be absorbed by the coating. The formation of accumulation between the film and the substrate will cause damage such as bubbling; and because the organic polymer contains a large amount of hydrophilic surfactants, it will also have a negative impact on the hydrophobicity of the paint film surface
