Embodiment 1～8

[0033] According to the weight ratio shown in the following tables 1 and 2, respectively prepare thermochromic water-based UV coatings, the specific preparation process is as follows:

[0034] (1) Add the photoinitiator, film-forming aid, and reactive diluent into the stirring tank in sequence, stir at 500-1000r / min for 5-10min, dissolve and mix evenly.

[0035] (2) Under the condition of stirring, add the water-based UV resin into the stirred tank, and stir for 10-15 minutes at the speed of 500-1000r / min. After mixing evenly, add deionized water, defoamer, emulsifier, wetting and leveling agent, thickener and temperature-sensitive color-changing material in sequence, disperse at 1000-3000r / min for 0.5-1h, filter and discharge , to obtain thermochromic water-based UV coatings.

Abstract

The invention discloses a thermochromic water-based UV coating which comprises the following components in percentage by mass: 30-60 percent of a water-based resin, 5-25 percent of a reactive diluent, 1-5 percent of a photoinitiator, 0.5-10 percent of a thermochromic material, 0.05-1 percent of a wet flatting agent, 0.05-2 percent of a thickening agent, 0.1-5 percent of an emulsifier, 0.1-2 percent of a defoaming agent, 0-8 percent of a coalescing agent and 25-60 percent of deionized water. The invention also discloses a method for preparing the thermochromic water-based UV coating. According to the thermochromic water-based UV coating provided by the invention, microcapsules do not need to be prepared in advance, the preparation process is simple and convenient, and large-scale industrial production is facilitated.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a thermochromic water-based UV coating and a construction method thereof. Background technique [0002] As people pay more attention to environmental protection, environmental protection legislation is becoming more and more perfect, and its implementation is becoming more and more strict, which greatly promotes the development and application of water-based UV coatings. Water-based UV coatings not only inherit the advantages of high efficiency, energy saving, environmental protection, economic applicability, but also replace the oily solvents with pungent smell and some active diluents in UV coatings with water, which can greatly reduce VOC emissions. Reduce air pollution and human injury. [0003] Thermochromic paint is a new type of special paint whose coating color changes with the change of surface temperature. Within a certain temperature range, a certain color change oc...
