Problems solved by technology

However, due to the low surface energy of silicone rubber and poor adhesion to plastics, it cannot be used in environments where the base material is plastic
Therefore, the existing filler-free anti-skid coatings have the disadvantages of insignificant anti-skid effect, complex production and processing technology, high cost and short anti-skid life.

Abstract

The invention belongs to the field of skidproof resin paint and discloses filler-free skidproof resin paint and its preparation method and use in fields of catering industry, home life and automobile industry and especially in field of food and drink pallet skid resistance. The filler-free skidproof resin paint comprises, by mass, 20-70% of elastic resin, 1-15% of a curing agent, 10-70% of a solvent and 3-30% of an auxiliary agent. The elastic resin rich in high activity groups such as hydroxyl undergoes a reaction to produce a polymer with a special molecular structure so that adhesion of the elastic resin to a base is improved, mechanical properties are improved, soft and elastic characteristics are retained and impact strength and wear resistance are improved. The filler-free skidproof resin paint is free of a skidproof filler. The coating of the filler-free skidproof resin paint has thickness of 30-100 microns, a friction coefficient of 0.90, a skidproof angle of 45 degrees, good adhesion to a base, good flexibility and elasticity, water and oil resistance, ultraviolet radiation resistance and a long service life.

Description

technical field [0001] The invention belongs to the field of anti-slip resin coatings, and in particular relates to a sprayable non-slip anti-slip resin coating without fillers, a preparation method thereof and applications in the fields of catering, home life, automobile industry and the like, and is especially suitable for anti-slipping of catering trays. Background technique [0002] At present, most of the existing anti-skid coatings at home and abroad use epoxy resin or polyurethane as binder, and use quartz sand, corundum, metal inorganic salts, ordinary polyurethane particles or rubber particles as anti-skid fillers. This kind of anti-slip coating can achieve the anti-slip effect by adding anti-slip fillers to make the surface of the coating rough and increase the coefficient of friction. However, the filler has poor stability in the coating system, and the problem of filler settlement or swelling and delamination of rubber particles is prone to occur. Moreover, due t...
