Pure water-base cold spray lacquer as well as preparation method and application thereof

Abstract

The invention relates to a pure water-base cold spray lacquer as well as a preparation method and an application thereof. The pure water-base cold spray lacquer comprises the following components in parts by weight: 45-60 parts of modified pure water-base polyhydric alcohol resin, 2-4 parts of diethanol amine, 12-25 parts of water-base amino resin and 15-26 parts of water. The preparation method comprises the following steps: adding diethanol amine into the modified pure water-base polyhydric alcohol resin; uniformly mixing and then adding water; uniformly mixing again, and then adding the water-base amino resin; uniformly dispersing and then de-foaming and filtering; and collecting filtrate, thereby acquiring the pure water-base cold spray lacquer. In the pure water-base cold spray lacquer provided by the invention, water is adopted for replacing a thinning agent in oil paint; after the completing of the paint spraying, water is used for washing, so that the effect of cold paint spraying surface is promoted; the use method is simplified; the production cost is lowered; the harmful matters, such as, benzene, added into the oil paint can be prevented; the pure water-base cold spray lacquer is environment-friendly and nontoxic; the prepared pure water-base cold spray lacquer has the qualified flexibility, adhesive force, salt mist resistance and water washing resistance.

Description

technical field [0001] The invention relates to the technical field of spray paint, in particular to a pure water-based cold spray paint and its preparation method and application. Background technique [0002] With the growing global clothing and luggage industry, people gradually increase the quality and appearance requirements of every detail of clothing and luggage, especially the quality and appearance of zippers and sliders directly determine the fate of products. Therefore, in the zipper industry, metal slider zipper electroplating, electrophoresis, spray painting, clasp and other processes have gradually proliferated. These processes can turn those ordinary and unattractive metal sliders and zippers into high-end appearance, colorful and durable. Products of. However, the current disadvantage is that these sliders, buttons, and zippers must be soaked or sprayed with paint to improve the appearance quality, and the paints they use are all solvent-based paints. First ...

Problems solved by technology

However, the current disadvantage is that these sliders, buttons, and zippers must be soaked or sprayed with paint to improve the appearance quality, and the paints they use are all solvent-based paints. First of all, they contain harmful substances such as benzene and formaldehyde. Most of the painters with senior working years have occupational diseases, and the proportion of serious diseases such as obstructive anemia and leukemia is quite high; secondly, with the gradual increase of global environmental protection pressure, especially the enhancement of environmental protection awareness of the general public in China, and the improvement of the government's environmental protection supervision level , choosing a good paint is already an indisputable reality in the zipper industry

However, most of the current solutions have only been slightly improved on the basis of oily paints, and the toxic and harmful substances have not been completely eradicated. Therefore, it is urgent to develop new paints that do not contain toxic and harmful substances.
