[0024] The preparation of the dual-nuclear metal phthalocyanine-loaded fiber material and its catalytic oxidation of formaldehyde are as follows: first, the dual-nuclear metal phthalocyanine-loaded fiber material is prepared by using an acid chloride-based binuclear metal phthalocyanine, and then the dual-nuclear metal phthalocyanine-loaded fiber material is placed in a formaldehyde-containing environment. Effective catalytic oxidation of formaldehyde in the environment.

[0025] A dual-nuclear metal phthalocyanine-loaded fiber material, which is prepared by reacting the acid chloride-based dual-nuclear metal phthalocyanine with the fiber material in an organic solvent to prepare a covalently bonded dual-nuclear metal phthalocyanine-loaded fiber material with catalytic oxidation of formaldehyde ,

[0026] The mass percentage of metal phthalocyanine in the dual-core metal phthalocyanine-loaded fiber is 0.1-10%.

Embodiment 1

[0037] Dissolve 0.4g of dodecanoyl chloride-based cobalt phthalocyanine in 100ml of DMF solution. After fully dissolving, add 5g of vacuum-dried silk fiber, stir, and treat at 80°C for 8h. After taking it out, wash it with distilled water and wash it with 0.1mol.L -1 Treat the NaOH solution at 70°C for half an hour, take it out, wash it with distilled water, and dry it to get the binuclear cobalt phthalocyanine-loaded fiber material.

[0038] Weigh 0.1kg of dual-nuclear cobalt phthalocyanine-loaded fiber material, then place the fiber in 100 cubic meters of newly renovated bedrooms, and the formaldehyde concentration is 7.1mg / m 3 (5ppm), at regular intervals, the concentration of formaldehyde is detected to test the effect of its catalytic oxidation of formaldehyde.

Embodiment 2

[0040] Dissolve 0.4g of lauryl chloride iron phthalocyanine in 100ml of DMF solution. After fully dissolving, add 5g of vacuum-dried silk fiber, stir, and treat at 80°C for 8h. After taking it out, wash it with distilled water and wash it with 0.1mol.L -1 Treat the NaOH solution at 70°C for half an hour, take it out, wash it with distilled water, and dry it to get the binuclear cobalt phthalocyanine-loaded fiber material.

[0041] Weigh 0.1kg of dual-core iron phthalocyanine-loaded fiber material, and then place the fiber in 100 cubic meters of newly renovated bedrooms with a formaldehyde concentration of 7.1mg / m 3 (5ppm), at regular intervals, the concentration of formaldehyde is detected to test the effect of its catalytic oxidation of formaldehyde.

Abstract

A binuclear metal phthalocyanine load fibrous material eliminates the formaldehyde and the preparation method. It uses the acid radical chloro- binuclear metal phthalocyanine to respond in the organic solvent with the fibrous material, to obtain the binuclear metal phthalocyanine load fibrous material conjoint by covalent that can catalyze oxidation formaldehyde; Its preparation method is: Uses the acid radical chloro- binuclear metal phthalocyanine to dissolve in the right amount organic solvent, after treating the full dissolution, joins after the vacuum drying the textile fiber, the agitation and responded under certain temperature, then takes out the textile fiber with the distilled water cleaning, carries on processing with the alkaline solution, finally uses the distilled water to clean, drying then; The catalyzed oxidation formaldehyde's method is: According to the formaldehyde density's difference, the name takes the ration the binuclear metal phthalocyanine load fibrous material, lays aside it in contains in the formaldehyde environment, carries on the effective catalyzed oxidation to the formaldehyde; And in the formaldehyde catalyzed oxidation processing step, the use temperature range is: - 50degree C-50degree C; The use barometric pressure scope is: - 0.01-10 standard atmospheric pressure; It has good effect to eliminate the formaldehyde, and can duplicate uses, raised its use factor, the preparation equipment is simple, the craft was simple and easy to operate.

Description

technical field [0001] The invention relates to a dual-nuclear metal phthalocyanine-loaded fiber material and a method for its preparation and catalytic oxidation treatment of formaldehyde, belonging to the field of materials and environmental treatment. Background technique [0002] With the improvement of people's living standards and aesthetic tastes, high-end home decoration has become more and more popular, and various decorations, furniture, floor panels, wall decoration materials, etc. have become indispensable in home decoration. At the same time, some imperceptible gas pollutants have brought a lot of discomfort and troubles to people, such as ammonia, hydrogen sulfide, benzaldehyde and other odors, among which formaldehyde gas is more common. According to statistics, within 1-6 months after decoration, the rate of formaldehyde exceeding the standard is as high as 80% in the living room, and close to 100% in the conference room and office; after 3 years of decoratio...
