Abstract

The invention discloses waterborne polyurethane spray paint for fabric and shoe materials and a preparation method of the waterborne polyurethane spray paint. The waterborne polyurethane spray paint is prepared from components such as waterborne polyurethane, water, toner and auxiliaries. The spray paint is good in dispersion stability, high in dyeing degree, good in brilliance, easy to process, free of sagging, free of bubbles, good in levelling, physical property and activation property, easy for secondary processing and free of polishing, can be bent for 130 thousand times or more, and is especially suitable for materials such as the fabric and the shoe materials.

Description

technical field [0001] The invention relates to a spray paint, in particular to a water-based spray paint, in particular to a special water-based polyurethane spray paint for fabrics and shoe materials and a preparation method thereof, belonging to the technical field of water-based paint. Background technique [0002] With the improvement of people's living standards, people's awareness of environmental protection is also increasing, and more and more people have begun to pay attention to the living environment of human beings themselves. Therefore, while pursuing fashion, people have also begun to pay attention to the choice of environmentally friendly coatings. Traditional solvent-based coatings contain a large amount of organic solvents, which will emit a large amount of VOC during production and construction, directly endangering human health and causing environmental pollution. According to relevant statistics, the global VOC emissions to the atmosphere are as high as ...
