Abstract

The invention discloses general-purpose acrylic polyurethane finishing paint for wood-metal and belongs to bi-component acrylic polyurethane coating. The acrylic polyurethane finishing paint is prepared through mixing a main paint component and a curing agent component according to the ratio of 4: 1. The main paint component is prepared through mixing the following ingredients: high-solid low-viscosity thermosetting hydroxy acrylic resin, stearic acid modified polyurethane resin, a good-weatherability ferrotitanium coloring pigment, pigments/fillers, a variety of adjuvants and a special solvent for environment-friendly acrylic polyurethane. The curing agent component is prepared from toluene diisocyanate and n-butyl acetate. The finishing paint has excellent weatherability, decorative performance and luster and color retention. A paint film is good in wear resistance and bright in color and luster and is tough and plump; and the general-purpose acrylic polyurethane finishing paint for the wood-metal has very high adhesive power to various steel structures and woods. The general-purpose acrylic polyurethane finishing paint for the wood-metal is applicable to surfaces of metallic steel structures and woods, cement products, electrical appliances and the like as anticorrosive decorative finishing paint.

Description

technical field [0001] The invention relates to a general-purpose acrylic polyurethane topcoat for metal and wood. Background technique [0002] Acrylic urethane coatings are a priority product for the coatings and paint industry. In the past few years, the development has surpassed alkyd products and has become one of the fastest growing varieties in the coatings industry. Traditional acrylic urethane topcoats are low solids, solvent based. With the increasingly stringent environmental protection regulations, the development of new resins has been developed internationally. At present, the coexistence of amino alkyd, thermoplastic acrylic and thermosetting acrylic has been formed. At present, in the paint products used on metal steel structure materials and wood materials, most metal wood coatings have many defects in terms of gloss, weather resistance, corrosion resistance and decorative performance due to the influence of the environment and climate and control costs. ...
