Embodiment 1

[0021] First, select the formula of elastic paint. The film-forming resin adopts 37.7% branched saturated polyester with hydroxyl group, 45.1% mixed solvent, 0.5% leveling agent, 0.2% drier, 4.5% matting powder, and chooses ACEMATT 3200 , 12% curing agent.

[0022] The production process is as follows: add 37.7% of a little branched saturated polyester with hydroxyl groups into the container, then add 45.1% of mixed solvent, 0.5% of leveling agent, 0.2% of drier, slowly add 4.5% of ACEMATT 3200 is dispersed for 30 minutes, and 12% HDI trimer curing agent is added to obtain a highly soft and environmentally friendly elastic paint.

Embodiment 2

[0024] The film-forming resin of this example adopts 40% branched saturated polyester with hydroxyl groups, 41.3% mixed solvent, 0.5% leveling agent, 0.2% drier, 6% matting powder, and selects ACEMATT 3300, 12% curing agent.

[0025] The production process is as follows: Add 40% of branched saturated polyester with hydroxyl groups into the container, then add 41.3% of mixed solvent, 0.5% of leveling agent, 0.2% of drier, slowly add 6% of ACEMATT 3300, disperse for 30 minutes, add 12% HDI trimer curing agent, that is, high soft feeling, low cost and environment-friendly elastic paint.

Abstract

The invention discloses high-softness environment-friendly elastic paint and a preparation method thereof, wherein the high-softness environment-friendly elastic paint comprises film-forming resin, a mixed solvent, a leveling feeling agent, a drier, flatting powder and a curing agent. Compared with the prior art, the invention can also achieve excellent elastic hand feeling after omitting high-cost elastic powder, has better weather resistance, can achieve a lower matt effect by adopting a novel flatting material, does not whiten and has better hand feeling and low cost, and a product conforms to an environmental protection standard of European Union.

Description

technical field [0001] The invention relates to an elastic paint and a preparation method thereof, in particular to an elastic paint with high softness and environmental protection and a preparation method thereof. Background technique [0002] With the improvement of people's living standards, the requirements for the appearance of daily necessities are getting higher and higher, such as: pearlescent aluminum powder effect, matte effect, elastic feel effect, especially the parts that are often touched by hands (such as tape measure box, mouse, mobile phone) Housings, dashboards, cosmetic boxes, etc.) require a flexible touch paint for a comfortable touch. [0003] Chinese patent application CN101173153A discloses the preparation of a kind of elastic paint. The patent uses elastic powder with high cost and organotin drier, but it has strong toxicity and is not environmentally friendly. It cannot pass the EU environmental protection certification, nor can it adapt to high-gra...
