Phase change thermal insulation paint and preparation method thereof

Abstract

The invention relates to the technical field of paint, in particular to a phase change thermal insulation paint and a preparation method thereof. The phase change thermal insulation paint is composed of a main agent and a curing agent in a ratio of 100:20. The main agent includes: 40.0-60.0 of hydroxyl acrylic resin, 0.5-1.5 parts of a dispersant, 0.2-0.8 part of a defoaming agent, 0.2-0.8 part of bentonite, 10.0-20.0 of pigment, 3.0-9.0 of filler, 3.0-9.0 of hollow glass beads, 10.0-20.0 of a phase change microcapsule, 0.2-0.8 of a leveling agent, and 10.0-20.0 of a mixed solvent. The curing agent comprises: 50.0-60.0 of aliphatic polyisocyanate resin, and 40.0-50.0 of anhydrous butyl acetate. The method provided by the invention is simple in operation, the prepared paint belongs to high performance thermal insulation finish paint, can achieve effective control of the surface and internal temperature of a coated object, by slowing down heat energy transfer and the storage and release process of heat energy in the phase change microcapsule, thermal insulation and constant temperature effects can be realized, at the same time the paint has excellent protection and decorative effects on the coated object, effectively saves energy and is environment-friendly, thus having good economic benefits.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a phase-change thermal insulation coating and a preparation method thereof, which are applied in the fields of aerospace, construction, automobile, environmental protection, medical care, cooling of electronic devices, military camouflage and the like. Background technique [0002] With the development of science and technology, economic construction and the needs of people's lives, the demand for thermal insulation technology has increased rapidly, and various thermal insulation materials have been developed and put into the market one after another. As a new thermal insulation material, phase change microcapsules The development and application of it have received widespread attention. Phase-change energy storage materials refer to substances that automatically absorb or release potential to the environment by using changes in the phase or structure of the material itself with...

AI Technical Summary

Problems solved by technology

[0003] At present, the thermal insulation materials used in coatings, such as hollow glass microspheres, foam materials, and thermal insulation boards, are all materials that delay temperature changes, and cannot keep the internal temperature of the coated object at a constant temperature within a certain range.
