Abstract

The invention discloses a graphene water spraying sheet and a preparation method thereof. The graphene water spraying sheet is prepared from the following main materials in parts by weight: 78 to 98 parts of PVC resin; 10 to 16 parts of vermiculite, 33 to 39 parts of high-temperature active bamboo charcoal powder; 40 to 60 parts of graphene powder; 31 to 41 parts of chlorinated polyvinyl chloride,13 to 17 parts of tribasic lead sulfate, 2 to 6 parts of barium stearate, 0.5 to 2.5 parts of p-hydroxyanisole, 1 to 3 parts of maleic anhydride, 7 to 9 parts of polyethylene glycol terephthalate, 5to 7 parts of polycarbonate, 11 to 13 parts of stilbene and 7 to 11 parts of diisobutyl phthalate. The graphene powder is added and matched with the honeycomb sheet type structure so that the surfacearea is well increased, and the heat dissipation effect of the water spraying sheet is improved.

Description

technical field [0001] The invention relates to the technical field of water-sprinkling fillers, in particular to a graphene water-sprinkling sheet and a preparation method thereof. Background technique [0002] Cooling tower water spray filler is the main part of the heat exchange between water and air in the cooling tower. It fully contacts the cooling water carrying waste heat with the air in the cooling tower, increases the heat dissipation, and prolongs the temperature of the cooling water in the cooling tower. The residence time increases the heat exchange area between the cooling water and the air, and distributes the water evenly, so that the temperature of the cooling water can be reduced evenly. [0003] The water spray sheet works in the cooling tower for a long time, and its temperature resistance, heat dissipation performance, and aging resistance are all required to be high. Prior art CN201810986757.0 A high-vicat water spray sheet for nuclear power plants and...
