Aluminum trichloride was cooled to 1°C at 3°C / min, and stirred for 6 hours to prepare 3-hydroxy-5-aminopropenyl phenbutene; under the conditions of 60°C and 2MPa, polytetrafluoroethylene with a molecular weight of 1600 was prepared. Ethylene fluoride and 3-hydroxy-5-aminopropenyl phenbutene were mixed in a mass ratio of 1:0.3, stirred at 500 r / min for 30 min, and then added dropwise at 40 drops / min of diphenyl peroxide with a mass of 0.1 times the mass of polytetrafluoroethylene Formyl was stirred at 900 r / min for 2 h, cooled to room temperature at 3 °C / min, filtered, washed twice wit...

Embodiment 2

[0038] A preparation method of an insect-proof and heat-insulating fabric, the preparation method of the insect-proof heat-insulating fabric comprises the following preparation steps:

[0039] (1) At room temperature and under argon protection, mix 2-chloropropenamine and o-hydroxybutenone in a mass ratio of 1:1.3, stir at 600 r / min for 15 min, and then add 0.02 times the mass of 2-chloropropenamine. Aluminum trichloride was cooled to 3°C at 4°C / min, and continued to stir for 7 h to prepare 3-hydroxy-5-aminopropenyl phenbutenone; under the conditions of 70°C and 3MPa, polytetrafluoroethylene with a molecular weight of 1800 was prepared. Ethylene fluoride and 3-hydroxy-5-aminopropenyl phenbutene were mixed at a mass ratio of 1:0.4, stirred at 600 r / min for 40 min, and then added dropwise with 0.2 times the mass of PTFE diphenyl peroxide at 50 drops / min Formyl was stirred at 1000r / min for 3h, cooled to room temperature at 4°C / min, filtered, washed three times with absolute ethan...

Embodiment 3

[0045] A preparation method of an insect-proof and heat-insulating fabric, the preparation method of the insect-proof heat-insulating fabric comprises the following preparation steps:

[0046] (1) At room temperature and under argon protection, mix 2-chloropropenamine and o-hydroxybutenone in a mass ratio of 1:1.4, stir at 700 r / min for 20 min, and then add 0.03 times the mass of 2-chloropropenamine. Aluminum trichloride was cooled down to 5°C at 5°C / min, and stirred for 8 hours to prepare 3-hydroxy-5-aminopropenyl ketene; under the conditions of 80°C and 4MPa, polytetrafluoroethylene with a molecular weight of 2000 was prepared. Ethylene fluoride and 3-hydroxy-5-aminopropenyl phenbutene were mixed at a mass ratio of 1:0.5, stirred at 700 r / min for 50 min, and then added dropwise at 60 drops / min of diphenyl peroxide with a mass of 0.3 times the mass of polytetrafluoroethylene Formyl was stirred at 1100r / min for 4h, cooled to room temperature at 5°C / min, filtered, washed 4 time...

Abstract

The invention discloses an insect-proof heat-insulating fabric and a preparation method thereof, and relates to the technical field of textiles. The insect-proof heat-insulating fabric prepared by the invention comprises a fabric base layer and a heat-insulating layer from bottom to top, the preparation method comprises the following steps: firstly, blending o-nitrophenylhydrazine tri (diethyl maleate) siloxane and 3-hydroxy o-aminobenzoic acid dichloro acetamide for spinning to form silicon dioxide aerogel and benzotriazole, and weaving to prepare a heat insulation layer; carrying out blended spinning on the polytetrafluoroethylene prepolymer and 3-hydroxy-5-amino propenyl benzene methyl ketone, and carrying out weaving, so as to obtain a fabric base layer; sequentially laying the fabric base layer and the heat insulation layer from bottom to top, and carrying out steam rolling treatment by utilizing phosphorus pentasulfide to form phosphate ester and thiobenzamide compounds, so as to prepare the insect-proof heat insulation fabric. The insect-proof and heat-insulating fabric prepared by the invention has good heat retaining property, ultraviolet resistance, flame retardance and insect resistance.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to an insect-proof and heat-insulating fabric and a preparation method thereof. Background technique [0002] In the daily firefighting process, the firefighters are most exposed to fire extinguishing work, which requires that the fabric of their protective clothing should not only be flame-retardant and fire-resistant, but also have a certain thermal insulation protection function. Among all the flame-retardant materials currently developed, the fabrics used for fire-fighting suits are either woven from high-temperature resistant organic fibers, or the fabrics are flame-retardant treated with flame retardants to obtain flame-retardant functional fabrics. The fabrics prepared by these two methods have only a certain flame retardancy, but are not thermally insulated. [0003] Moreover, in the remote areas of Hainan, Yunnan, Guangxi, Guizhou, etc., mosquitoes, midges, gnats, and fle...
