Abstract

The invention discloses a water-based self-luminous elastic coating, and a preparation method and an application thereof. The water-based self-luminous elastic coating comprises a coating component and a curing agent component; the coating component comprises the components in parts by mass: 10-20 parts of modified oily elastic resin, 10-30 parts of water-based polyurethane elastic resin, 1-2 parts of an emulsifier, 0.3-0.6 part of a base material wetting agent, 30-40 parts of a water-based energy storage material, 0.01-2 parts of a water-based luminous material, 1-3 parts of a dispersing agent, 1-3 parts of extinction powder, 0.7-2 parts of an auxiliary agent and 20-40 parts of water. According to the water-based self-luminous elastic coating, modified oily elastic resin and water-based polyurethane elastic resin are used as main film-forming resin and are subjected to reaction with molecules of the curing agent component, and a compact net-shaped structure is formed, so that the hardness, boiling resistance and wear resistance of the coating are remarkably improved, a formed paint film is good in elasticity and fine and smooth in hand feeling, has the advantages of boiling resistance, weather resistance, wear resistance and the like, has the adhesive force of 5B, the hardness of H and high luminous intensity, and can emit light for 12 h or more after absorbing light for 10-20min.

Description

technical field [0001] The invention relates to the field of water-based paints, in particular to a water-based self-luminous elastic paint. In addition, the present invention also relates to a preparation method and application of the above-mentioned water-based self-luminous elastic coating. Background technique [0002] With the continuous improvement of people's awareness of environmental protection, water-based coatings are accepted by more people as a more environmentally friendly coating material, and the prospects for water-based coatings are getting better and better. Water-based coatings eliminate the risk of fire during construction and reduce air pollution. Water-based coatings use water as a solvent, which saves a lot of resources. Only a small amount of low-toxic alcohol ether organic solvents are used, which improves the working environment and has a significant effect on reducing pollution and saving resources. [0003] However, there are many gaps between ...
