Problems solved by technology

[0003] At present, most of the common heat insulation materials on the market cannot have both heat insulation and light transmission properties at the same time. When the light transmission of a heat insulation material is better, its heat insulation ability is often worse; The better the heat capacity, the poorer the light transmittance

Embodiment 1

[0025] Embodiment 1: Preparation of light-absorbing heat-storage composition

[0026] First, antimony tin oxide (purchased from Japan Ishihara Co.) and 3-aminopropyltriethoxysilane are added to alcohol with a volume percentage of 95%, and after being thoroughly mixed and stirred, an antimony tin oxide suspension is obtained . Wherein, the ratio of antimony to tin in the selected antimony tin oxide is 1:9, the particle size of the antimony tin oxide is 10-20 nanometers, and the antimony tin oxide: 3-aminopropyltriethoxy The weight ratio of silane:alcohol is 30:2:68.

[0027] Next, the antimony tin oxide suspension was continuously ball milled by a ball mill for 6 hours at a rotational speed of 1000 rpm using 1 mm zirconium beads to form a dispersed antimony tin oxide slurry.

[0028] Afterwards, the dispersed antimony-tin oxide slurry is spray-dried under the technological condition that the drying temperature is 100° C. to obtain a dried antimony-tin oxide mixed powder. The...

[0031] Embodiment 2: Preparation of light-absorbing heat-storage composition

[0032] In this example, the light-absorbing and thermal-storage composition is roughly prepared by the method of the above-mentioned Example 1, the difference is that stearic acid is added as a lubricant during the preparation process of this example, and the detailed preparation method is as follows:

[0033] Firstly, antimony tin oxide, 3-aminopropyltriethoxysilane and stearic acid are added into 95% alcohol by volume, and after being thoroughly mixed and stirred, the antimony tin oxide suspension is obtained. Among them, the weight ratio of antimony tin oxide: 3-aminopropyltriethoxysilane: stearic acid: alcohol is 30:1:1:68.

[0034]Next, the antimony tin oxide suspension was continuously ball milled by a ball mill for 6 hours at a rotational speed of 1000 rpm using 1 mm zirconium beads to form a dispersed antimony tin oxide slurry.

[0035] Afterwards, the dispersed antimony-tin oxide slurry is...

Embodiment 3

[0038] Embodiment 3: Preparation of light-absorbing heat-storage composition

[0039] In this example, the light-absorbing and thermal-storage composition was prepared roughly by the method of Example 1 above, the difference being that the dispersant used in this example was Solsperse 20000, which was purchased from Lubrizol, USA.

[0040] The specific components and contents of light-absorbing and heat-storage microparticles, dispersants and polymers in the light-absorbing and heat-storage composition prepared in this example are shown in Table 1.

Abstract

The invention provides a light absorbing and heat accumulating composition. The composition is prepared by melting and extruding a mixture composed of a composition containing light absorbing and heat accumulating micro particles and polymer. The composition containing light absorbing and heat accumulating micro particles comprises at least one light absorbing and heat accumulating micro particle and a dispersant that coats the light absorbing and heat accumulating micro particle. The diameter of the light absorbing and heat accumulating micro particle that is dispersed in the polymer is in a range of 10 to 800 nano meters. According to the structure mentioned above, the provided light absorbing and heat accumulating composition can effectively absorb near infrared to achieve the goals of light absorption, heat insulation and heat accumulation. Moreover, the light absorbing and heat accumulating structure prepared from the light absorbing and heat accumulating composition has the advantages of good light transmittance, high near infrared shielding rate, and excellent light absorbing and heat radiation performance, and thus the buildings or vehicles that use the provided structure can maintain a good temperature balance.

Description

technical field [0001] The present invention relates to a light-absorbing and heat-storage composition, in particular to a light-absorbing and heat-storage composition that can effectively absorb near-infrared rays and store heat. In addition, the present invention also relates to a light-absorbing and heat-storage structure prepared from the above-mentioned light-absorbing and heat-storage composition. Background technique [0002] In response to energy saving policies, how to develop a light-absorbing heat-storage material suitable for windows of buildings and / or vehicles has always been an active research and development goal of various circles. [0003] At present, most of the common heat insulation materials on the market cannot have both heat insulation and light transmission properties at the same time. When the light transmission of a heat insulation material is better, its heat insulation ability is often worse; The better the heat capacity, the poorer the light tr...
