Description
Technical Field
The invention relates to the technical field of paint production, in particular to a UV (ultraviolet) curing color nano heat-insulating paint and a preparation method thereof.
Background
The paint is a continuous film which is coated on the surface of the protected or decorated object and can form firm adhesion with the coated object, and is usually a viscous liquid prepared by using resin, oil or emulsion as main materials, adding or not adding pigment and filler, adding corresponding auxiliary agents and using organic solvent or water.
The heat-insulating coating refers to a recently developed functional water-based coating for blocking, reflecting and radiating the near infrared heat of sunlight, so that the roof is heat-insulated and cooled, and the energy is saved and the consumption is reduced. Has the characteristics of heat insulation, water resistance, rust resistance, corrosion resistance, short construction period and quick response, the water spraying system is comprehensively replaced, and the heat-insulating cotton, the foaming sponge, the interlayer iron sheet and the like are used. The heat insulating paint is classified into three kinds of heat insulating paint, reflecting heat insulating paint and radiating heat insulating paint. Besides the three types of heat-insulating coatings, the foreign heat-insulating functional coating has a heat-insulating coating which has the advantages of the heat-insulating coating and also has a peculiar heat-insulating effect.
At present, although the commercial heat-insulating paint has a certain heat-insulating effect, the heat-insulating paint can be aged to different degrees after being irradiated by sunlight for a long time, namely, the ageing resistance is relatively poor, and the service life of the heat-insulating paint is shortened to a certain extent. Furthermore, the heat insulation performance is relatively poor, and further improvement or promotion is still required. Therefore, the invention provides a UV-cured color nano heat-insulating coating and a preparation method thereof, so as to solve the related technical problems.
Disclosure of Invention
The invention aims to provide the UV-cured color nano heat-insulating coating and the preparation method thereof, and the prepared coating product not only has excellent heat-insulating performance, but also has excellent ageing resistance, so that the quality of the coating product is ensured to a certain extent, and the service life of the coating product is prolonged.
In order to achieve the above purpose, the present invention provides the following technical solutions:
The UV curing color nano heat-insulating coating comprises the following components in parts by weight: 35 to 50 parts of polyurethane modified acrylic resin, 25 to 40 parts of bisphenol A epoxy acrylate, 45 to 60 parts of 1, 6-hexanediol diacrylate, 0.6 to 0.9 part of polyamide wax, 5 to 8 parts of photoinitiator, 7 to 12 parts of functional additive, 5 to 10 parts of nano powder mixture, 0.3 to 0.8 part of flatting agent, 0.5 to 0.8 part of dispersing agent, 0.3 to 0.6 part of defoamer, 10 to 25 parts of pigment and 20 to 40 parts of filler;
The molecular weight of the bisphenol A epoxy acrylate is 500-700, and the viscosity is 20000-35000 mPa.s/25 ℃;
the leveling agent is a Digatego 450 leveling agent; the defoamer is Pick BYK-055 defoamer; the dispersing agent is an Epoff card EFKA-4010 dispersing agent;
