example 1

[0018] A kind of antistatic water-based UV coating is processed by the raw materials of following parts by weight:

[0019]

[0020] Wherein, the photoinitiator is 2-hydroxyl-2methyl-1-phenyl-acetone; the leveling agent is polyether polyester modified organosiloxane; the antistatic agent is ethyl Oxylated alkylamine; the purity specification of the co-solvent is analytically pure.

[0021] The preparation method of antistatic water-based UV paint of the present invention is:

[0022] 1. Weigh each component according to the above mass ratio;

[0023] 2. Mix polyvinyl alcohol, water-based unsaturated polyester acrylate resin and polyurethane acrylate resin to prepare a mixture;

[0024] 3. After adding photoinitiator, leveling agent and antistatic agent into the mixture, stir for 0.5h;

[0025] 4. Use the phase inversion method to slowly add water and co-solvent to disperse into a stable emulsion, and the dropping time is 1h.

Abstract

The invention discloses an antistatic water-borne UV coating. The antistatic water-borne UV coating is characterized by being processed by the following raw materials in parts by weight: 30-40 parts of urethane acrylate resin, 20-40 parts of waterborne unsaturated polyester acrylate resin, 5-10 parts of polyvinyl alcohol, 1-1.5 parts of a photoinitiator, 0.2-0.5 part of a flatting agent, 2-4 parts of a cosolvent, 3-5 parts of an antistatic agent, 3-5 parts of rutile titanium dioxide and 100-200 parts of water, wherein the photoinitiator is 2-hydroxyl-2-methyl-1-phenyl-acetone; the flatting agent is polyether-polyester-modified organosiloxane; the antistatic agent is ethoxylation alkylamine; and the purity specification of the cosolvent is analytically pure. The antistatic water-borne UV coating disclosed by the invention has the advantages of good hardness, good abrasive resistance, antistatic electricity, economy and environmental friendliness.

Description

technical field [0001] The invention belongs to the technical field of coatings, in particular to an antistatic water-based UV coating. Background technique [0002] In recent years, environmental pollution has become more and more serious, seriously threatening our living space and life safety, and prompting people to strengthen their awareness of environmental protection. Countries around the world have successively formulated environmental protection regulations and strictly limited emission standards, such as the tail gas emission standards formulated by my country, heterocyclic Discharge standards for water pollutants in the pesticide-like industry and water pollutants in the fermentation-based pharmaceutical industry are designed to encourage the promotion of new products that are environmentally friendly, energy-saving and emission-reducing. Therefore, in the field of paint coating, the development and application of safe and low-volatile organic water-based, powder an...
