Embodiment 1

[0043] Example 1 Preparation of Gd 0.1 La 0.9 B 6 Powder, including the following steps:

[0044] (1) Press Gd:La:B:Na:SiO 2 The molar ratio is the ratio of 0.1:0.9:6:24:12, respectively weighing Gd 2 (CO 3 ) 3 495g, La 2 (CO 3 ) 3 2060g, B 2 O 3 2089g, Na 552g, SiO 2 720g, all the raw materials were put into the autoclave, 12 moles of hydrogen were introduced, heated to 320°C, and stirred for two hours. The obtained product was extracted with deionized water and separated into layers, the precipitated part was filtered and washed with water for 5 times, and the obtained product was dried at 110° C. for 5 hours. After drying, the product and 6 kg of deionized water were loaded into a sand mill and ground for 8 hours. After testing, the particle size of the slurry was 500-700 nanometers. The slurry was first spray granulated and dried, and the particle size of the obtained powder was 700 nanometers. -800 nm. The 700-800 nanometer powder is subjected to the secon...

Embodiment 2

[0047] Example 2 Preparation of Ce 0.1 La 0.9 B 6 Powder, as Ce:La:B:Na:SiO 2 The molar ratio is 0.1:0.9:6:24:12, respectively weighing Ce(NO 3 ) 3 326g, La 2 (CO 3 ) 3 2060g, B 2 O 3 2089g, Na 552g, SiO 2 720g, the remaining steps are the same as 1.1 to prepare Gd 0.1 La 0.9 B 6 The steps for powder are the same.

Embodiment 3

[0048] Example 3 Preparation of Sm 0.1 La 0.9 B 6 Powder, according to Sm:La:B:Na:SiO 2 The molar ratio is 0.1:0.9:6:24:12, respectively weigh Sm(NO 3 ) 3 336g, La 2 (CO 3 ) 3 2060g, B 2 O 3 2089g, Na 552g, SiO 2 720g, the remaining steps are the same as 1.1 to prepare Gd 0.1 La 0.9 B 6 The steps for powder are the same.

Abstract

The invention provides a rare-earth-based infrared heating thermal fabric and a preparation method and application thereof.The rare-earth-based infrared heating thermal fabric comprises a heating layer and a heat transfer thermal layer, the heating layer is formed by weaving rare-earth-based infrared heating yarn, and the rare-earth-based infrared heating yarn is prepared by dipping yarn in rare-earth-based infrared heating dipping liquid; the heat-transfer warm-keeping layer is formed by weaving rare-earth-based heat-transfer yarns, and the rare-earth-based heat-transfer yarns are prepared by dipping yarns in rare-earth-based high-heat-transfer dipping liquid. The rare-earth-based infrared heating warm-keeping fabric is simple in structure, the manufacturing cost of traditional heating element warm-keeping clothes is remarkably reduced, and cleaning is convenient.

Description

technical field [0001] The invention belongs to the technical field of textile fabrics, and in particular relates to a rare earth-based infrared heating warm-up fabric and a preparation method and application thereof. Background technique [0002] There are three ways of heat loss: heat conduction, heat convection and heat radiation. At present, the conventional practice of thermal clothing on the market is to use the bulkiness of down or cotton to prevent the flow of air, prevent the rapid loss of body heat, and achieve the effect of keeping warm. This method can only reduce the loss of heat, and cannot actively provide warmth to the body. With the advancement of textile technology and technology, in order to further improve the thermal insulation effect of clothing, heating elements are added to the clothing, and the heating elements are connected through various wires to maintain the heating effect with batteries, such as the patent CN201420501751.7 "The use of lithium ba...
