Water-based anti-skid coating and preparation method thereof

Abstract

The invention provides a water-based anti-skid coating and a preparation method thereof. The water-based anti-skid coating comprises a component A and a component B. The component A comprises, by mass, 8-10 parts of water, 35-40 parts of an acrylic emulsion, 30-35 parts of anti-skid particles with a particle size range of 0.2-2 mm and 15-30 parts of a functional auxiliary agent, and the component B is a water-based acrylic curing agent; and the functional auxiliary agent comprises 0.5-2 parts of a suspending agent, 1-5 parts of an emulsifier and 4-5 parts of an organic polymer anti-skid auxiliary agent. The invention relates to the water-based anti-skid coating which comprises 30-35 parts of the anti-skid particles with the particle size range of 0.2-2mm, the anti-skid particles can be stably combined with an emulsion coating and are stable in physicochemical property, and due to the fact that the particle size of the anti-skid particles is controlled within 0.2-2 mm, the water-based anti-skid coating can be directly sprayed to a coated base material from a spray gun. Compared with an existing coating, the coating of the invention has the advantages of more convenient spraying mode and film forming speed, reduction of the existing process flow and saving of the construction time cost.

Description

technical field [0001] The invention relates to a water-based anti-slip coating and a preparation method thereof, belonging to the technical field of anti-slip coatings. Background technique [0002] In recent years, water-based anti-slip coatings are widely used in public places, ship decks, workshop floors, train roofs, air conditioners, etc., to change the friction of the coated substrate. Its 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 dissolved in water, the 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 component and B component used in combination. A component is a resin e...

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.
