Embodiment 1

[0031] At room temperature, use deionized water to prepare 150mL1mol / L vanadium oxide solution, 10mL1mol / L sodium tungstate solution, and 100mL2mol / L ammonium bicarbonate solution, first mix the sodium tungstate solution and vanadyl sulfate solution In a three-necked flask, stir for 5-10min at a stirring rate of 350-400rpm, then use a constant-flow pump to drip the ammonium bicarbonate solution into the above mixed solution within 60min, and continue stirring for 1-2h after the addition is complete, and the obtained precipitate passes through 220nm microporous membrane filter under reduced pressure, wash with deionized water until no SO 4 2- , washed with absolute ethanol, and vacuum-dried at 45°C to obtain a yellow-brown powder. The powder is calcined at a high temperature of 700-800° C. for 3 hours in an atmosphere furnace under a nitrogen atmosphere, and then continuously calcined at a nitrogen atmosphere of 500-600° C. for 2-3 hours to obtain a phase change material.

Embodiment 2

[0033]At room temperature, use deionized water to prepare 100mL of 0.05mol / L vanadium oxide solution, 5mL of 1mol / L ammonium tungstate solution, and 150mL of 0.1mol / L sodium bicarbonate solution. The solution is mixed and placed in a three-necked flask, stirred at a stirring rate of 270-300rpm for 20min, then using a constant flow pump to drop the sodium bicarbonate solution into the above mixed solution within 100-120min, and continue stirring for 3-5h after the addition is complete , the resulting precipitate was filtered with a 4# sand core funnel under reduced pressure, washed with deionized water until no SO 4 2- , Wash with absolute ethanol for 1-2 times, and dry under vacuum at 60°C. The obtained powder is calcined at a high temperature of 600-700° C. for 9 hours under an argon atmosphere in an atmosphere furnace, and then continuously calcined at 400-500° C. for 1 hour under an argon atmosphere to obtain a phase change material.

Embodiment 3

[0035] At room temperature, use deionized water to prepare 200mL0.5mol / L vanadium oxide solution, 10mL0.5mol / L sodium tungstate solution, 10mL0.5mol / L ammonium molybdate solution, and 150mL0.5mol / L sodium carbonate solution Solution, firstly mix sodium tungstate solution, ammonium molybdate solution and vanadyl sulfate solution and place them in a three-necked flask, stir for 25-30min at a stirring rate of 200-250rpm, and then use a constant flow pump to pump carbonic acid within 70-90min Add the sodium solution dropwise into the above mixed solution, and continue to stir for 8-10 hours after the dropwise addition, and the obtained precipitate is filtered through a 220nm microporous membrane under reduced pressure and washed with deionized water until there is no SO 4 2- , washed with acetone, vacuum dried at 30°C, then calcined at 900-1000°C for 2 hours under a nitrogen atmosphere, and then continued to be calcined at 700-800°C for 5-8 hours under a nitrogen atmosphere to obt...

Abstract

The invention relates to a temperature-regulating intelligent tent fabric and a preparation method of the temperature-regulating intelligent tent fabric. The temperature-regulating intelligent tent fabric comprises a paulin matrix and a temperature-regulating coating, wherein the temperature-regulating coating comprises doped vanadium dioxide (V (1-x)Mx)O2 nanopowder or micelle, wherein 0 <= x <= 0.03. The preparation method of the temperature-regulating intelligent tent fabric comprises the following steps of: (1) preparing doped (V(1-x)Mx)O2; and (2) applying the doped (V(1-x)Mx)O2 to the paulin matrix by coating, padding or impregnating to obtain the temperature-regulating intelligent tent fabric. The temperature-regulating intelligent tent fabric can effectively improve the temperature in a tent, greatly improve the degree of comfort of a user and play a good role in the aspects of field construction, amusement and tourism, geological exploration, rescue and relief work, field hospitals and outdoor banquets, is easy to operate, is low in cost and has a good application prospect.

Description

technical field [0001] The invention belongs to the field of tent fabrics and its preparation, and in particular relates to a temperature-controlled intelligent tent fabric and a preparation method thereof. Background technique [0002] At present, tents are mainly used in field construction operations, camping training, outdoor exhibitions, sports and entertainment venues, military command posts, field hospitals, emergency rescue and disaster relief, field camping, leisure travel, etc. It is easy to assemble and disassemble and easy to carry. Widely used in many fields. Although the tent provides people with a shelter from the wind and rain, the temperature difference between the inside and outside of the tent makes many users feel uncomfortable. The Lanzhou Regional Climate Center of the Gansu Provincial Meteorological Bureau conducted hourly (192 times) comparative observations of the temperature inside and outside the tents where the people in the disaster-stricken area...
