Problems solved by technology

Therefore, the use of solar absorbing materials has become a new solution. Japanese Patent Application Laid-Open No. 1-132816 uses zirconium carbide, antimony oxide, and tin oxide as solar absorbing materials, which can absorb near-infrared rays in sunlight, but although they contain Zirconium carbide, antimony oxide, and tin oxide fibers can absorb sunlight and store heat, but the far-infrared radiation efficiency of zirconium carbide, antimony oxide, and tin oxide is not good, so their thermal insulation effect is limited, and they can be used in places where there is no sunlight or weak sunlight. The indoor environment does not have the effect of light absorption and heat storage

Embodiment 1

[0049] Embodiment 1: Preparation of heat storage heat preservation masterbatch and heat preservation products

[0050]

[0051] After fully mixing the compound powder of tungsten bronze compound, antimony-doped tin oxide and titanium nitride, dispersant and masterbatch carrier polymer with a certain proportion, using a high-speed mixer, the twin-screw extruder is used to Blending, melting and extruding the well-mixed mixture at a temperature of 250°C to 280°C to obtain a heat storage and heat preservation masterbatch.

[0052] In this example, the inorganic ceramic powders with photothermal response effect were all synthesized by the inventors through solid phase method. Among them, tungsten bronze is cesium tungsten bronze with Cs 0.32 WO 3 The molecular formula, the particle size is between 40nm and 100nm. The atomic ratio of antimony to tin in antimony-doped tin oxide is 1:9, and the particle size is between 5nm and 25nm. The particle size of titanium nitride is betwe...

Embodiment 2

[0060] Embodiment 2: Preparation of thermal storage and thermal insulation masterbatch and thermal insulation products

[0061]

[0062] After fully mixing the compound powder of tungsten bronze compound, antimony-doped tin oxide and titanium nitride, dispersant and masterbatch carrier polymer with a certain proportion, using a high-speed mixer, the twin-screw extruder is used to Blending, melting and extruding the well-mixed mixture at a temperature of 220°C to 250°C to obtain a heat storage and heat preservation masterbatch.

[0063] The inorganic powders with photothermal response effect in this example were all synthesized by the inventor himself (the synthesis method is the same as in Example 1). Among them, tungsten bronze is cesium tungsten bronze with Cs 0.32 WO 3 Molecular formula, the particle size is between 40nm and 100nm; the atomic ratio of antimony to tin in antimony-doped tin oxide is 1:9, the particle size is between 5nm and 25nm; the particle size of tita...

Embodiment 3

[0069] Embodiment 3: Preparation of thermal storage and thermal insulation masterbatch and thermal insulation products

[0070] This embodiment is similar to Embodiment 2. Compared with Embodiment 2, this embodiment has the following differences.

[0071] In the production of heat storage and heat preservation masterbatch, the mass ratio of inorganic ceramic powder with photothermal effect, dispersant and carrier polymer is 1:0.1:3.9, that is, based on the total mass of the heat storage heat preservation masterbatch, it has light and heat The content of thermally responsive inorganic ceramic powder is 20% by mass.

[0072] In the production of heat storage and heat preservation fibers, the heat storage and heat preservation masterbatch is mixed with the fiber matrix polymer at a mass ratio of 1:19. Based on the total mass of the heat storage and heat preservation fiber, the fiber contains 1 mass percent of inorganic ceramic powder with photothermal response effect.

Abstract

The invention relates to a master batch with heat storage and insulation functions, a master batch product and a preparation method of the master batch. The master batch comprises a polymeric carrierand ceramic powder, and the ceramic powder is one or a combined and compounded object of a tungsten bronze compound, antimony-doped, fluorine-doped or antimony and fluorine co-doped tin oxide and titanium nitride. The heat storage and insulation product simultaneously applicable to indoor space and outdoor space can be prepared by the master batch, and the master batch is simultaneously applicableto underwear and coats with heat insulation functions when being used for garment fabrics.

Description

technical field [0001] The invention relates to a heat storage heat preservation master batch, a heat preservation product made from the master batch and a preparation method. The heat storage and heat preservation masterbatch belongs to the field of composite materials, and the product belongs to the field of chemical fiber film and textile. Background technique [0002] In order to achieve the thermal insulation effect without affecting the comfort due to the increase in the thickness of the clothes, heat storage and thermal insulation functional fabrics are currently attracting attention, and many companies in the industry are competing to launch new thermal insulation fabrics. The main technologies adopted now are: fiber composites of various materials, moisture-absorbing and heating fibers, and adding far-infrared radiation materials to the fibers to increase the thermal insulation effect. [0003] In terms of composite synthetic fabrics, "LUNAFA" of Kurabo Industries ...
