preparation example Construction

[0045] In the preparation of the resin composition according to the present invention, the first monomer is essential. As mentioned above, the inventors have surprisingly found that by introducing the first monomer, that is, an ethylenically unsaturated monomer containing a poly(oxyalkylene) segment, during the preparation of the resin composition, it is possible to maintain the The viscosity is significantly reduced while the solid content is high, so that the resin composition can be formulated into a solvent-based coating composition with a VOC emission of no more than 420g / L without additional diluents.

[0046] Therefore, the present invention also relates to the use of the above-mentioned ethylenically unsaturated monomers containing poly(oxyalkylene) segments for the preparation of the high-solid and low-viscosity resin composition comprising an acrylic copolymer according to the present invention.

[0047] Preferably, the components used to prepare the resin compositio...

Abstract

The present invention relates to a high-solid low-viscosity resin composition comprising an acrylic copolymer, wherein the resin composition has a solid content of at least about 80 wt%, based on theweight of the acrylic copolymer, and a viscosity of 130,000 mPa*s or less measured with a BROOKFEELD viscometer at 25 DEG C, and the main chain of the acrylic copolymer has a suspended poly (oxyalkylene) fragment.

Description

technical field [0001] The invention relates to a high-solid and low-viscosity resin composition, in particular to a resin composition containing an acrylic copolymer. The present invention also relates to a solvent-borne coating composition comprising said resin composition. Background technique [0002] In recent years, with people's attention to the environment, many countries have enacted environmental laws and required further reduction of the amount of VOCs that are allowed to be released into the air from coating compositions, especially solvent-based coating compositions. For example, in China, since February 2015, solvent-based coating compositions with VOC content exceeding 420g / L will be subject to additional consumption tax at a rate of up to 4%, which will greatly increase the cost of coating companies. Therefore, the demand for high-solid and low-viscosity resin compositions for formulating solvent-based coating compositions with a VOC content of not more than...
