Non-slip coatings are no stranger to people. Non-slip floors can be seen on pedestrian bridges, stadiums, ship decks, offshore platforms, and floating bridges. Anti-slip property is the basic characteristic of anti-slip coating, and it is a special function of the coating film. Carborundum anti-slip coatings mainly contain non-slip granules, film-forming resins, etc. Anti-slip granules are additives that improve the anti-slip function of paint films, giving paint films anti-skid ability to prevent people from slipping and falling; film-forming resins have the effect of fixing anti-skid pellets Maintain the substrate together without damage. In foreign countries, the development and utilization of anti-slip coatings has a long history. Emery anti-slip coating binder. Alkyd resin, oxidized rubber, phenolic resin or modified epoxy resin with good weather resistance and mechanical function are usually selected, which is mixed with hard and large particles, such as cheap quartz sand or the like . These filler particles are large and protrude from the surface, which creates a large frictional resistance, and then reaches the intention of anti-slip. In order to reduce the abrasion resistance of non-slip particles, Japan Asahi Paint Co., Ltd. uses a high-filled rubber powder as a non-slip filler for hard epoxy resins. The American MIC company has reported a polyurethane coating with hollow glass balls as a filler. After it is under heavy pressure, it still has a much higher anti-slip property than ordinary anti-slip coatings; Germany uses ethylene copolymer hollow spheres as anti-slip agents, and its adhesion is particularly good. The hollow spheres rupture under pressure and remain in a sturdy small basin shape. On the coating surface. 金刚砂 、氧化铁以及普通的橡胶颗粒为防滑涂料。 Most of the existing domestic products use epoxy resin or polyurethane as the binder, and quartz sand, silicon carbide , iron oxide, and ordinary rubber particles as the non-slip coating. Most of these products are not satisfactory in terms of impact resistance, abrasion resistance, and adhesion. They have shortcomings such as fragility, shedding, and short service life.
