Abstract

The invention provides water-based paint for outdoor metal furniture. The water-based paint is prepared from, by weight, 40-70 parts of fluorocarbon-modified acrylic resin, 5-20 parts of water, 5-20 parts of cross-linked resin, 3-8 parts of matting powder, 1-3 parts of thickener and 0-5 parts of other auxiliaries. The water-based paint for the outdoor metal furniture has excellent weather resistance, water resistance and impact strength, can have excellent adhesion to metal substrates, has the advantages of excellent stain resistance, corrosion resistance and full film coating and can well meet the performance requirements of the outdoor metal furniture. The invention also provides a preparation method of the water-based paint for the outdoor metal furniture.

Description

technical field [0001] The invention relates to the technical field of water-based paint, in particular to a water-based paint for outdoor metal furniture and a preparation method thereof. Background technique [0002] As a new life in the furniture industry, outdoor metal furniture has appeared in the market on a large scale, such as outdoor garden tables and chairs, park chairs and beach chairs. The characteristics of outdoor metal furniture are that they can be placed outdoors, are comfortable and casual, have good corrosion resistance, and are durable, so they are deeply loved by people. However, the particularity of the outdoor environment requires metal furniture to withstand the test of wind, rain, and sun, and must have the ability to resist ultraviolet rays, rain, acid and alkali corrosion, etc. Therefore, it is necessary to carry out special treatment on the metal surface, and the most common and direct and effective method is to paint the metal surface. At prese...
