Abstract

The invention discloses a double-component water-based resin and a paint prepared from the resin. A water-based acrylic acid modified polyurethane resin and a water-based inorganic polysiloxane resin are firstly prepared; and the water-based double-component organic inorganic paint is prepared by using the water-based acrylic acid modified polyurethane resin as the organic component and the inorganic polysiloxane resin as the inorganic component. The acrylic acid has excellent yellowing resistance, the polyurethane has excellent toughness, and the acrylic acid and polyurethane are integrated to obtain the complementary organic component; the inorganic component has excellent erosion resistance, solvent resistance, radiation resistance, heat resistance and aging resistance; and thus, the prepared paint has the high hardness, high water resistance and excellent solvent resistance of the inorganic paint, and the toughness of the organic paint.

Description

technical field [0001] The invention is designed for furniture decoration and decoration, especially relates to a water-based acrylic modified polyurethane resin and a water-based inorganic polysiloxane resin and a preparation method thereof, and a water-based two-component organic-inorganic coating prepared by using the two water-based resins. Background technique [0002] Since 2015, my country has successively formulated some regulations and policies. From January 1, 2015, the "Environmental Protection Law" was officially implemented. The new "Environmental Protection Law" has greatly strengthened the punishment of enterprises. In order to promote energy conservation and environmental protection, approved by the State Council, Consumption tax will be imposed on batteries and paints from February 1, 2015. The introduction of the most stringent environmental protection law in history and the collection of paint consumption tax have brought severe challenges to the traditiona...
