Problems solved by technology

[0003] However, the above coatings have the following defects: (1) The above products are all solvent-based products, with high VOC emissions, great damage to the environment, and affect the health of construction workers; (2) The coating has low surface energy, so recoating There are defects, and the adhesion between layers is weak. Once the coating fails and you want to repair it, it will be difficult to adhere; (3) The anti-ice and snow performance of the coating is low and requires multiple repairs;
[0004] In addition, even for water-based paints, the general water-based paint products on the market have a short shelf life, only 3 to 6 months. If they are stored for a long time, they will lose their protective effect and cause a lot of waste in actual production.

Abstract

An aqueous two-component ice and snow resistant coating comprises a main agent A and a hardener B, which are (3-6):1 in mass ratio, wherein the main agent A comprises the raw materials in part by weight as follows: 40-76 parts of acrylic acid polymer aqueous emulsion, 15-30 parts of fluororesin emulsion, 1-4.6 parts of surfactant, 5-20 parts of water, 3.6-8.3 parts of film forming adjuvant, 0-0.3 part of pH conditioning agent, 0.5-2 parts of ultraviolet light absorbent and 0-0.2 part of thickening agent; and the hardener B comprises the raw materials in part by weight as follows: 50-100 parts of solvent-free or aqueous polyisocyanate and 0-15 parts of BAC (butyl acetate). The coating can be well matched and compatible with various coated old coatings or substrates, has good adhesive force, is durable, strong in ice and snow resistance, simple in preparation method and suitable for ice and snow prevention of metallic equipment, fiber glass reinforced plastic equipment, wires and communication equipment of trains, automobiles, aircrafts, ships and the like.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a water-based anti-ice and snow coating and a production method thereof. Background technique [0002] The method to prevent ice and snow from covering and accumulating on the surface of buildings, open-air equipment and other objects is mainly to construct a thin layer interface on the surface of the substrate to reduce the surface tension so that ice cannot adhere to it. At present, the main method includes the use of fluorine Resin, silicone and other materials to reduce its surface energy. The domestic patent with application number 201210222 372.x discloses a kind of anti-icing and snow coating containing polyacrylate grafted polydimethylsiloxane (PDMS) copolymer containing polysilsesquioxane (POSS), which uses organic Silicon material to achieve anti-icing and snow; Beijing Zhisheng Weihua company is prepared by alternating multi-block inorganic-organic interpenetrating n...
