Problems solved by technology

[0004] The main component of traditional sports facility coatings is polyurethane resin. Polyurethane resin has good water resistance, high and low temperature resistance, and aging resistance. less efficient
[0005] The Chinese invention patent with the publication number CN107353792A discloses a wear-resistant water-based coating for sports venues and its preparation method. Compared with traditional coatings, the abrasion resistance, corrosion resistance and plasticity of the coating of the invention are improved to a certain extent, but the single-component The water-based polyurethane resin base liquid itself does not have wear resistance, and the wear resistance mainly provided by adding nano-titanium dioxide and carbon fiber still cannot reach the required wear resistance
[0006] The Chinese invention patent with the notification number CN105176366B is a preparation method of wear-resistant and anti-bacterial sports equipment coatings. Compared with traditional coatings, the wear resistance of the coatings prepared by the invention is improved to a certain extent, but the preparation method is relatively complicated and is not suitable for practical use. mass production

Abstract

The invention belongs to the field of coating manufacturing, and particularly relates to a method for preparing a coating for a sports facility. The method comprises the following preparation steps that 1, crylic acid prepolymer is prepared; 2, crylic acid modified polyurethane resin is prepared from the obtained crylic acid prepolymer; 3, the obtained crylic acid modified polyurethane resin and water-based fluororesin emulsion are mixed to be uniform, and basic mixed liquid is prepared; 4, a mixed aid prepared from a dispersing agent, a thickening agent, a coalescing agent, a flatting agent,an antifoaming agent, an antirust agent, a wear-resisting agent and a low molecular lubricating agent is prepared; 5, the basic mixed liquid prepared in step 3 and the mixed aid prepared in step 4 areadded to a diffuser to be dispersed to be uniform. The prepared coating for the sports facility has good wear resisting and rust preventing performance, it can be guaranteed that it is avoided that the surface of the outdoor sports facility is exposed to the air due to friction damage, and consequently rust is generated, the preparation steps are simple, and the method is suitable for large-scaleproducing application.

Description

technical field [0001] The invention belongs to the field of paint manufacturing, and in particular relates to a preparation method of paint for sports facilities. Background technique [0002] Modern people pursue a healthy life, regular exercise in their spare time can not only relieve fatigue but also help physical and mental health, achieve the effect of weight loss and fitness, and the sports field is the main place for people to exercise at present. As the number increases, the degree of wear and tear on sports facilities by athletes gradually increases, and most of the sports facilities are in the open air, exposed to natural light for a long time and under the natural environment of wind and rain, it is easy to rust rotting condition. [0003] Existing sports facilities generally use baking paint or spray paint to beautify and protect their surfaces. However, long-term exposure to the outdoors, ultraviolet light, and rain washing will cause the surface protective p...
