Water-based paint for Christmas glass ornaments, and preparation method and application thereof

Abstract

The invention discloses a water-based paint for Christmas glass ornaments, and a preparation method and application thereof, belonging to the field of paints. The water-based paint comprises the following components in parts by weight (totaling 100 parts): 10-45 parts of water-based acrylic resin, 0-10 parts of water-soluble curing agent, 0-20 parts of filler, 0.1-1 part of water-based defoaming agent, 0-1 part of water-based dispersant, 0.1-1 part of water-based wetting agent, 0.1-2 parts of coupling agent, 4-30 parts of cosolvent and the balance of deionized water. The preparation method comprises the following steps: adding water-based resin and part of cosolvent into a stirring kettle, adding defoaming agent, dispersant and wetting agent, respectively and sequentially adding filler, water-soluble curing agent and silane coupling agent, finally adding residual cosolvent and water, and stirring to form a uniform water-based paint. The paint has the advantages of simple technique, low cost, low carbon, environmental protection, favorable water resistance and favorable weather resistance, and can be used for large-area mechanical construction.

Description

technical field [0001] The invention belongs to the field of coatings, in particular to a water-based coating and a preparation method thereof, which are mainly used in Christmas glass ornaments. Background technique [0002] At present, water-based coatings are mainly sprayed or sprayed on the surface of Christmas glass ornaments to decorate and beautify the environment. As a kind of Christmas decoration, Christmas glass ornaments have a very attractive market. In 2006, Yiwu Foster Arts & Crafts Co., Ltd., the largest handicraft company in China, exported more than 50 million Christmas ornaments. Jiangsu Baoying has a group of enterprises specializing in the production of Christmas glass ornaments. China has become the main market for Christmas glass ornaments in America, Europe and Asia. supplying country.

AI Technical Summary

Problems solved by technology

[0003] However, most manufacturers still continue to use solvent-based glass coatings for Christmas glass ornaments at present, and it has the following disadvantages: 1. When oily glass coatings are being constructed, more than 50% of organic solvents (toluene, toluene, Xylene, industrial alcohol, etc.) are solvents, and polluting, flammable, and volatile gases will cause great harm to the human body; 2. The price of organic solvents is expensive, which increases costs; 3. Oily glass coatings are flammable and require storage safety. High, increasing operating costs

The water-based color transparent glass paint that Chinese patent CN 1948200A introduces is applied on the Christmas glass ornament, but its preparation process is single, can not prepare the water-based transparent or solid color glass paint of various luster, simultaneously because its application process is brushing, can not be big Mechanical construction of the area, the uniformity of the coating cannot be guaranteed
