A kind of anti-slip coating for sports equipment

Abstract

The invention discloses an anti-skid coating for athletic sports appliances. The anti-skid coating comprises the raw materials by the weight percentage: 30-40% of modified amino silicone resin, 10-15%of titanium dioxide, 10-15% of cerium oxide, 8-12% of a composite anti-skid agent, 1.5-3% of a coupling agent, 4-7% of a curing agent, 0.5-1.3% of a leveling agent, 0.2-0.5% of a defoamer, and the balance a solvent. The composite anti-skid agent comprises the raw materials in parts by mass: 4-7 parts of silk fibers, 15-20 parts of montmorillonite powder and 1-2.5 parts of a 0.8% acetyloxy ethoxysilane ethanol solution. The prepared anti-skid coating has good wear resistance, good skid resistance and good adhesion force, weather resistance and light aging resistance, has good skid resistance and abrasion resistance even at low temperature in winter, does not damage human skin, has simple technology, and can be used in industrial production and application.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to an anti-slip coating for sports equipment. Background technique [0002] Initially, anti-skid coatings were mainly used for the anti-skid of military and civilian ships and helicopter landing platforms of offshore oil platforms and the anti-skid of pedestrian deck passages. Now it has been widely used in metal or non-metal floors or platforms, escalators and other places in industrial and mining enterprises that have high requirements for anti-skid, dust-proof or anti-corrosion floors. Sports equipment is widely used now, and is distributed indoors and outdoors. When people use sports equipment, due to sweating, the equipment is relatively slippery, which has certain dangers. [0003] At present, there are many applications of anti-slip coatings, which are divided into three categories by adding anti-slip agents: one type uses inorganic sand as anti-slip aggregates,...

Problems solved by technology

Sports equipment is now widely used and distributed indoors and outdoors. When people use sports equipment, due to sweating, the equipment is slippery, which has a certain degree of danger.

[0003] At present, there are many applications of anti-slip coatings, which are divided into three categories by adding anti-slip agents: one type uses inorganic sand as anti-slip aggregates, such as silica sand, quartz sand, glass hollow beads, emery, ceramsite, crystalline alumina Etc., the anti-slip coating with this kind of anti-slip particles is characterized by: large friction, easy to obtain raw materials, and low cost, but this anti-slip agent has a large proportion, and it is easy to precipitate when mixed with paint, and the spraying gun is blocked, so manual spraying has to be adopted. Sand, clean up the non-bonding sand after cleaning, so the construction is troublesome, the sand grains are uneven, although the initial friction is large, but it is easy to wear and fall off later, and the service life is short. The second type of anti-slip agent uses organic compound pellets, such as synthetic resin. 1. Waste rubber particles. Although the price of this type of anti-slip agent is higher than that of inorganic pellets, it has suitable hardness and elasticity, no sharp edges and corners, can withstand friction and impact, is not easy to break, has good adhesion, and is not easy to fall off. Compared with inorganic pellets, the initial friction Smaller, but longer life, and the specific gravity is similar to the base material, not easy to settle, convenient construction, suitable for spraying, uniform pellets, but must prevent the phenomenon of swelling and delamination of pellets and solvents; the third type of anti-skid coating is no anti-skid coating Agent pellets, mainly the molecular design of the base resin of the paint, highly active group components, generate strong polarity on the surface of the paint film, and surface contact produces movement resistance. This anti-skid paint is currently in the trial stage

[0004] In the cold winter, the surface of outdoor sports equipment will freeze, and the elasticity of the existing polyurethane anti-skid coating will change, which is prone to coating wear; after freezing, the hardness of the paint film will increase rapidly, and the anti-skid particles on the surface of the paint film will change Form a hard contact surface. The sliding of hard materials such as steel on the paint film is a point contact, which reduces the contact surface between the coating and the hard material, resulting in a sharp decrease in friction resistance, and the problem of poor anti-skid effect. In severe cases, people fall Falling on hard, uneven, sharp sports equipment is prone to injury
