Embodiment Construction

[0021] In order to describe the present invention more clearly, this method will be described in detail below in conjunction with some specific implementation examples. Of course, the scope of protection of the present invention is not limited thereto.

[0022] One aspect of the present invention provides a radiation heat dissipation coating, which is used to cool the boiled water when coated on a water cup. The radiation heat dissipation coating contains the following components in parts by mass:

[0023]

[0024] Among the components of the above-mentioned radiation heat dissipation coating, the epoxy resin is a solvent-free epoxy resin with an epoxy value of 0.4-0.5; the carbon nanotubes are multi-walled carbon nanotubes, preferably 3-4nm in diameter, and 3-4 μm; the purity of the boron nitride is 99.9%, and the average particle size is less than 1 μm; the anti-sedimentation agent is at least one of organic bentonite, amide wax, and hydrogenated castor oil; the coupling ...

Abstract

The invention provides a radiation cooling coating. The radiation cooling coating comprises, by mass, 60-70 parts of epoxy resin, 0.5-1 part of carbon nanotubes, 15-20 parts of boron nitride powder, 0.5-1 part of an anti-settling agent, 0.5-1 part of a coupling agent and 20-30 parts of a curing agent. The invention also provides a preparation method of the radiation cooling coating. The radiationcooling coating can enhance radiation heat dissipation, reliably and timely cool heated plain boiled water and quickly provide plain boiled water with the most suitable drinking water temperature forpeople.

Description

technical field [0001] The invention relates to a radiation heat dissipation cooling paint used for quick cooling of boiled water and a preparation method thereof, belonging to the technical field of radiation cooling paint. Background technique [0002] In recent years, schools all over the country have spent a lot of money to configure boiled water dispensers to provide students with boiled water for drinking. According to the survey, every primary and middle school student needs to drink about 2000 milliliters of water every day to keep the water balance. But, 100 ℃ of cooling in the water heater is cooled down to drinkable temperature, need to wait for a long time, the break time between classes of middle and primary schools is shorter (generally 10 minutes), therefore, the drinkable belt during break for middle and primary schools is given to primary and middle school students. It is inconvenient to come, which affects the normal drinking volume of boiled water. [00...
