Problems solved by technology

[0004] The water-based anti-skid coating with anti-skid function is also composed of two parts, one part is a water-based emulsion coating composed of components A and B, and the other part is anti-skid particles with anti-skid function. The existing water-based anti-skid coating technology is mostly Spray the water-based emulsion paint with a spray gun first, and then spray the anti-skid particles again. Repeat this process 2-3 times to satisfy the coating of the water-based anti-skid paint; Within the particle size range of 2-4mm, it cannot be directly sprayed with a spray gun and sprayed together with water-based anti-slip coatings. In addition, even if anti-slip particles with a suitable particle size range are used for the spray gun, the anti-slip particles will also have poor adhesion to water-based emulsion coatings. It is not easy to combine and cannot achieve a good film-forming effect. Therefore, the spraying process of water-based anti-skid coatings has always been complicated, low in efficiency, and slow in speed, which is not conducive to improving the construction speed.

Abstract

The invention provides a water-based anti-skid coating and a preparation method thereof, comprising A component and B component, and in parts by mass, the A component includes 8-10 parts of water, 35-40 parts of acrylic emulsion, 30-35 parts of Anti-slip particles with a particle size range of 0.2-2 mm and 15-30 parts of functional additives, the B component is a water-based acrylic curing agent; the functional additives include 0.5-2 parts of suspending agent, 1-5 parts of emulsifying agent, 4-5 parts of organic polymer anti-skid additives. The invention relates to a water-based anti-slip coating, which includes 30-35 parts of anti-slip particles with a particle size range of 0.2-2mm. The anti-slip particles can be stably combined with the emulsion coating and have stable physical and chemical properties. Due to the anti-slip particles The particle size is controlled within 0.2-2mm. This kind of water-based anti-slip coating can be directly sprayed from the spray gun to the coated substrate. Compared with the existing coatings, it has a more convenient spraying method and film-forming speed, which reduces the existing process flow and saves construction. time cost.

Description

technical field [0001] The invention relates to a water-based anti-skid coating and a preparation method, and belongs to the technical field of anti-skid coatings. Background technique [0002] In recent years, water-based anti-skid coatings have been widely used in public places, ship decks, workshop floors, train roofs, air conditioners, etc. to change the friction of the coated substrate. The advantages are good adhesion, roughness and effective anti-skid. [0003] Water-based coatings refer to coatings that use water as a solvent or as a dispersion medium. Since the resin in water-based coatings is partially soluble in water, water-based coatings are heterogeneous. Therefore, the better the hydrophilicity of the resin, the smaller the particle size formed. , the better the dispersion of the resin in the water phase, the better the stability of the coating. Ordinary water-based paints include A and B which are mixed together. A is a resin emulsion and B is a curing agent...
