Abstract

The invention relates to the photocatalyst application field, in particular to a method for manufacturing a photocatalyst protection clothes. The method comprises the following steps of: sterilizing base cloth by using alcohol, spraying a photocatalyst onto the base cloth to form a thickness of 30 nanometers, then drying the base cloth, performing compensated spraying again, drying the base cloth, and tailoring and sewing the base cloth after the base cloth is detected to be qualified so as to form the photocatalyst protection clothes. The photocatalyst protection clothes has the functions of sterilization, elimination of peculiar smell and air purification; the photocatalyst coating is not dissipated and can be used for long time; and meanwhile, titanium dioxide is nontoxic and innocuous.

Description

A kind of preparation method of photocatalyst protection clothes

Technical field

The present invention relates to the photocatalyst application, concretely, relate to a kind of preparation method of photocatalyst protection clothes.

Background technology

The formaldehyde that exists in the environment, benzene, harmful substances such as ammonia can cause cancer, respiratory disease, causes immunity degradation, and particularly children if immunity is low, are easy to cases with leukemia; In hospital, public transport, cinema, market and waiting room, because personnel are intensive, flow is big, is easy to generate cross-infection, even causes the propagation of epidemic disease.

Photocatalyst is exactly a photochemical catalyst, is a kind of reaction speed that can accelerate reactant, and the material that itself before and after reaction, does not change, its main component is a titanium dioxide.Photocatalyst can effectively be degraded and be removed airborne benzene series thing, halogenated alkane, aldehyde, ketone, acid etc.; Can decompose airborne planktonic bacteria, kill bacteriums such as Escherichia coli, yellow staphylococcus, tinea alba bacterium, mould, suppuration bacterium, green pus bacterium, suppress propagation as cause of diseases such as enterovirus, influenza, filterable virus; Can kill mould, prevent to go mouldy; Can discharge anion, fresh air, so photocatalyst becomes the ideal material of curbing environmental pollution in the world now.

Photocatalyst is applied to the cloth surface, dry back forms film, under the irradiation of light, titanium dioxide granule is as catalyst, utilize luminous energy to carry out catalytic action, produce charged particle under the UV-irradiation in light source, react with airborne water and oxygen, produce negative oxygen ion and hydroxyl ion, anion and hydroxyl ion have the oxidability greater than 120kcal/mol, can destroy the cell membrane of bacterium, and cytoplasm is run off and death, can also solidify the protein of virus, suppress virus activity, and catch airborne various planktonic bacteria, but the ability antibiotic and sterilizing, eliminate peculiar smell, purify air, and photo-catalytic coating layer itself can not consume, can use for a long time, simultaneously, titanium dioxide itself is nontoxic.

Summary of the invention

The technical problem to be solved in the present invention provides the disappear preparation method of photocatalyst protection clothes of smelly, antifouling de-sludging of a kind of sterilization.

The technical scheme concrete steps that the present invention will solve are as follows:

(1) with the alcohol disinfecting basic unit cloth of 30%-50%, is 60 ℃ in temperature and dried 50 minutes down.

(2) be pH value 7, concentration is 0.6% photocatalyst, and wherein the particle diameter of titanium dioxide is 10nm, and percentage composition is 2.5%, is 45 ℃ in temperature, and the pressure 0.6MPa of spray gun sprays under the flow 450ml/min on basic unit's cloth.

(3) after spraying formation thickness is 30nm, is 60 ℃ in temperature and dried 50 minutes down.

(4) at the pressure 0.4MPa of spray gun, dried 50 minutes under temperature is 60 ℃ compensation spraying back under the flow 200ml/min.

(5) carry out Tyndall effect detect qualified after, moulding is made in cutting, stitching.

Basic unit's cloth can be textile cloth, also can be organic cloth, the polytetrafluoroethylene (PTFE) in the organic matter, its chemical property is highly stable, add that wherein the set bond energy of carbon and fluorine is very strong, can be complementary to have durable characteristic with the active oxygen bond energy that the photocatalyst reflection is burdened with.

After adopting such scheme, compared with prior art have following beneficial effect:

(1) comprehensive: photocatalyst effectively degradation of formaldehyde, benzene,toluene,xylene, ammonia, etc. pollutant, and have the antiseptic property of high-efficiency broad spectrum, the toxin that bacterium or fungi can be discharged decomposes and harmless treatment.

(2) continuation: in course of reaction, photocatalyst itself can not change and loss, can continual purifying contaminated thing under the irradiation of light, have the advantage of lasting, continuous action of time.

(3) security: nontoxic, harmless, safe and reliable to human body; Final product is carbon dioxide, water and other innocuous substances, can not produce secondary pollution.

(4) high efficiency: photocatalyst utilizes luminous energy such as inexhaustible solar energy just the environmental contaminants that spread can be removed purification under the low concentration state.
