Abstract

The invention discloses a sports field bottom layer coating material, which comprises, by weight, 5800-5830 parts of an anionic hydrophobic modified acrylic thickener, 3800-3940 parts of an aqueous acrylic polyurethane resin, 18-20 parts of a liquid-state metal-based defoaming agent, 90-100 parts of polyethylene wax, 180-200 parts of a pre-dispersion body, 300-500 parts of an adhesion promoter, and 7-10 parts of marine vegetable powder. With the sports field bottom layer coating material of the present invention, the sports field bottom layer has good mechanical strength.

Description

technical field [0001] The invention relates to the technical field of coatings, more specifically, it relates to a sports ground primer and a preparation method thereof. Background technique [0002] With the development of our country's social economy, the concept of national fitness is becoming more and more popular among the people. Every city, every community or unit will build different types of sports venues to provide convenience for fitness and competitions. The acrylic stadium coating system does not contain asbestos, lead or mercury and other compounds, which is in line with the principle of environmental protection; it is green and environmentally friendly, highly resistant to ultraviolet light, and the color is durable and deep, does not fade or fall off; it is easy to maintain and the maintenance cost is low. Both are sturdy and durable; a variety of colors are available, including blue, red, dark green and light green. [0003] At present, the Chinese patent ...
