Embodiment 1

[0011] A preparation method for a frost-resistant and heat-preserving coating, comprising the following steps: (1) taking 29kg of phenolic resin, 15kg of tung oil, and 5kg of polypropylene, and dissolving the phenolic resin, tung oil, and polypropylene evenly after heating; (2) Add 13kg of methylcyclopentane, 14kg of triacetin, and 15kg of ethylene glycol, dissolve again, and stir evenly after dissolving; (3) finally add 19kg of water, stir again, and stir until the mixture is evenly mixed, The evenly mixed paint liquid is sealed and preserved to prepare a freeze-resistant and heat-retaining paint.

Embodiment 2

[0013] A preparation method for a frost-resistant and heat-preserving coating, comprising the following steps: (1) taking 19kg of phenolic resin, 12kg of tung oil, and 7kg of polypropylene, and dissolving the phenolic resin, tung oil, and polypropylene evenly after heating; (2) Add 8kg of methylcyclopentane, 15kg of triacetin, and 19kg of ethylene glycol, dissolve again, and stir evenly after dissolving; (3) finally add 16kg of water, stir again, and stir until the mixture is evenly mixed, The evenly mixed paint liquid is sealed and preserved to prepare a freeze-resistant and heat-retaining paint.

Embodiment 3

[0015] A preparation method for a frost-resistant and heat-preserving coating, comprising the following steps: (1) taking 24kg of phenolic resin, 13kg of tung oil, and 8kg of polypropylene, and dissolving the phenolic resin, tung oil, and polypropylene evenly after heating; (2) Add 11kg of methylcyclopentane, 17kg of triacetin, and 17kg of ethylene glycol, dissolve again, and stir evenly after dissolving; (3) finally add 17kg of water, stir again, and stir until the mixture is evenly mixed, The evenly mixed paint liquid is sealed and preserved to prepare a freeze-resistant and heat-retaining paint.

[0016] After the coatings were prepared, the antifreeze performance and thermal insulation performance of the coatings in Example 1, Example 2, and Example 3 were measured. The coatings of Example 1, Example 2, and Example 3 were stored at -40°C, -30°C, and -20°C for 60 days respectively, and the state changes of the coatings were observed. Measured and measured the thermal condu...

Abstract

The invention discloses an antifreeze and insulated coating and a preparation method thereof. The antifreeze and insulated coating is prepared from the following components in parts by weight: 19-29 parts of phenolic resin, 12-15 parts of tung oil, 5-8 parts of polypropylene, 8-13 parts of methylcyclopentane, 14-17 parts of glyceryl triacetate, 15-19 parts of ethylene glycol and 16-19 parts of water. The formula components of the coating are dissolved, agitated and sealed to obtain the antifreeze and insulated coating, and the prepared coating has excellent anti-frost property and thermal insulation properties, and can be applied to a low-temperature environment.

Description

technical field [0001] The invention relates to a coating and a preparation method thereof, in particular to a frost-resistant and heat-retaining coating and a preparation method thereof. Background technique [0002] In some cold regions and low-temperature environments, after the paint is applied to the surface of the wall, due to climate reasons, the paint will remain in the low-temperature environment for a long time, and the performance of the paint will change greatly, reducing the paint's durability. performance stability. Under low temperature conditions, since the composition of the paint does not have frost resistance, the shape of the paint will change, which will affect the use of the paint. Conventional walls are usually treated with thermal insulation, and the wall material has a certain degree of thermal insulation. If the coating also has good thermal insulation performance, it will further improve the thermal insulation performance of the building and reduc...
