Embodiment 1

[0047] A blue coating with high near-infrared reflection. The blue coating is mainly composed of an ellipsoidal ultramarine material and a film-forming agent, and the mass ratio of the ellipsoidal ultramarine material to polyvinylidene fluoride is 8.5:1.5.

[0048] The raw materials of the above-mentioned ellipsoidal ultramarine material include 2.5g 4A molecular sieve, 3g sulfur powder, 0.6g sodium carbonate, 0.5g quartz powder and 0.3g rosin.

[0049] The synthesis method of the above-mentioned ellipsoidal ultramarine material is as follows: 2.5g of 4A molecular sieve, 3g of sulfur powder, 0.6g of sodium carbonate, 0.5g of quartz powder, and 0.3g of rosin are ground and mixed. Pour the uniformly mixed material into a covered quartz crucible and compact it, then put the quartz crucible into a muffle furnace for heat treatment. The heat treatment procedure is: raise the temperature from room temperature to 450°C, keep it warm for 30 minutes, and then continue to heat up After ...

Abstract

The invention discloses an ultramarine material which comprises the following raw materials in parts by weight: 30-40 parts of a 4A molecular sieve; 40-50 parts of sulfur powder; 5-10 parts of quartzpowder; 4-10 parts of rosin; and 4-10 parts of sodium carbonate. The invention also discloses a preparation method of the ultramarine material. The method comprises the following steps: (1) mixing andcompacting the 4A molecular sieve, quartz powder, sulfur powder, anhydrous sodium carbonate and rosin to obtain a mixture; and (2) carrying out first-stage low-temperature heat treatment and second-stage high-temperature heat treatment on the mixture, and purifying to obtain the ultramarine material. The invention also discloses a near-infrared high-reflection blue coating and a preparation method thereof. The ultramarine material synthesized by the method has high reflectivity in a near-infrared band, can reflect 75-90% of energy of the sun in the near-infrared band, can reduce absorption ofthe coating to solar heat to the maximum extent, and achieves the purpose of reducing energy consumption.

Description

technical field [0001] The invention belongs to the field of materials, and in particular relates to a pigment and a preparation method thereof, and a coating and a preparation method thereof. Background technique [0002] In order to meet people's aesthetic needs, more and more buildings and equipment surfaces are painted with colored coatings. However, in the hot summer, due to solar radiation, the surface of the building will heat up, reducing the environmental comfort of indoor workers. A common solution is to use cooling equipment such as air conditioners to cool down, but this will cause a large amount of energy consumption. 52% of the energy of solar radiation is distributed in the near-infrared band (780-2500nm). For colored coatings, if the energy in the near-infrared band can be reflected to the greatest extent, it can effectively reduce the absorption of solar energy by buildings and reduce energy consumption. [0003] As a widely used coating, blue coating has...
