Problems solved by technology

[0006] However, the existing anti-radiation clothing should be rinsed as much as possible when washing, and should not be rubbed, twisted, twisted, etc., and should not be folded when stored after drying, because its fabric contains metal components, which are afraid of being washed off or broken, which reduces the anti-radiation effect. Electromagnetic radiation shielding performance and service life
Metal fiber blended fabrics, half-silver fiber blended fabrics, all-silver fiber knitted fabrics and polyion fabrics in radiation protection clothing can be washed, and the shielding effect is significantly reduced after washing

Embodiment 1

[0024] Embodiment 1, the preparation of nano metal particles

[0025] 1) Dissolve silver nitrate, copper nitrate, and PVPK-30 in deionized water at high temperature, and prepare solutions with concentrations of 1.6mmol / mL, 0.8mmol / mL, and 3.2mmol / mL, respectively, and stir at 400 rpm. The three solutions are mixed uniformly to obtain a mixed solution, and the mol ratio of silver nitrate, copper nitrate and PVPK-30 in the mixed solution is 2:1:4;

[0026] 2) According to the ratio of silver nitrate, copper nitrate and hydrazine hydrate molar ratio of 2:1:5, it is configured into an aqueous solution of hydrazine hydrate with a concentration of 3.6mmol / mL, stirred at 400 rpm, and the mixed liquid obtained in step 1) is mixed into droplets Add it to the aqueous solution of hydrazine hydrate, adjust the pH value to 6.7 with ammonia water, react at 65°C for 1.5h, then separate, wash, and dry at 50°C to obtain nanometer metal particles.

Embodiment 2

[0027] Embodiment 2, the preparation of permanent anti-electromagnetic radiation fabric

[0028] The anti-electromagnetic radiation coating is composed of the following raw materials in weight percentage: 5.2% polyvinyl alcohol, 2.1% polyvinyl acetate emulsion, 30% nano metal particles prepared in Example 1, and the balance is water.

[0029] According to the above formula, mix the raw materials and put them into the mixing heating pot to heat, make the temperature of each raw material reach 75 ℃, stir into a slurry; then pour the slurry into the grinder for 15 minutes, filter 200 mesh The finished anti-electromagnetic radiation coating is obtained by sieving, and coated on the surface of flexible fiber fabrics, the thickness is controlled at 150 μm, pre-baked at 110°C for 2 minutes, cured at 130°C for 12 minutes, and placed for 24 hours.

Embodiment 3

[0030] Embodiment 3, the preparation of permanent anti-electromagnetic radiation fabric

[0031] The anti-electromagnetic radiation coating is composed of the following raw materials in weight percentage: 1% polyvinyl alcohol, 0.1% polyvinyl acetate emulsion, 15% nano metal particles prepared in Example 1, and the balance is water.

[0032]According to the above formula, mix the raw materials and put them into the mixing heating pot to heat, make the temperature of each raw material reach 75 ℃, stir into a slurry; then pour the slurry into the grinder for 15 minutes, filter 200 mesh The finished anti-electromagnetic radiation coating is obtained by sieving, and coated on the surface of flexible fiber fabrics, the thickness is controlled at 150 μm, pre-baked at 110°C for 2 minutes, cured at 130°C for 12 minutes, and placed for 24 hours.

Abstract

The invention belongs to the field of textile materials, and relates to a permanent electromagnetic radiation resistant fabric. According to the technical scheme, warp and weft yarns of the permanent electromagnetic radiation resistant fabric are flexible fibers; an electromagnetic radiation resistant coating is arranged on the surface of the fabric and consists of the following raw materials in percentage by weight: 1-10 percent of polyvinyl alcohol, 0.1-3 percent of polyvinyl acetate emulsion, 1.8-2.8 percent of hydroxymethyl cellulose, 15-50 percent of nano metal particles and the balance of water. The permanent electromagnetic radiation resistant fabric disclosed by the invention can shield electromagnetic waves, and the shielding rate is over 99.9 percent; the shielding performance is over 54dB, and the popularization signification is great.

Description

technical field [0001] The invention belongs to the field of textile materials and relates to a permanent anti-electromagnetic radiation fabric. Background technique [0002] The range of electromagnetic radiation is very wide, including neutron rays, X-rays, γ-rays, α-rays, ultraviolet rays, infrared rays, electromagnetic waves, cosmic rays, lasers, microwaves and more than a dozen types of radiation protection, these rays bring human beings The Gospel has been brought, but it has also brought harm, the harm of electromagnetic radiation pollution. [0003] Electromagnetic radiation pollution is also known as electronic smog pollution. When high-voltage lines, substations, radio stations, television stations, radar stations, electromagnetic wave transmitting towers and electronic instruments, medical equipment, office automation equipment and household appliances such as microwave ovens, radios, televisions and mobile phones work, they will produce Various electromagnetic w...
