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

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. [0003] However, most manufacturers still continue to use solvent-based glass coatings for Christmas glass ornaments at present, and it has the following disadvantage...
