Description

Aldehyde-removing radiation-proof sun-shading composite fabric

Technical Field

The utility model relates to a remove aldehyde radiation protection sunshade compound fabric belongs to function fabrics field.

Background

Formaldehyde is a major indoor air pollutant and originates from artificial boards, furniture, paints, etc. used in interior decoration. Short term exposure to low concentrations of formaldehyde can lead to conjunctivitis, rhinitis, pharyngitis, etc., and long term exposure to high or low concentrations of formaldehyde can cause laryngeal spasm, pulmonary edema, pneumonia, and even death.

At present, the methods for removing formaldehyde mainly comprise the following methods. (1) Physical adsorption method. Physical adsorption technology is the most common method for purifying formaldehyde, and mainly depends on activated carbon and the like to adsorb formaldehyde. Commonly used adsorbent materials include zeolite, porous materials, honeycomb activated carbon, silica gel, spherical activated carbon, activated alumina, and the like. (2) Chemical absorption method. The chemical absorption method utilizes the characteristic that gaseous formaldehyde is easily dissolved in water, and the adsorption is promoted to be carried out by means of chemical reaction on the surface of an adsorbent. Generally, a complexing agent or an oxidizing agent is added into the absorption liquid to change the chemical structure and further destroy the molecular structure of the formaldehyde gas so as to reduce the concentration of the formaldehyde gas in the air. (3) A biological purification method. The biological purification method is to remove formaldehyde by absorption of plants or decomposition of bacteria. (4) A catalytic oxidation process. The catalytic oxidation method can be classified into a photocatalytic method and a metal oxide method. The photocatalytic degradation method mainly depends on a photocatalyst, and the photocatalyst is a substance which does not change under the irradiation of light and can promote chemical reaction. The metal oxidation process does not require light energy and generally relies on the oxidative and surface properties of the metal oxide to decompose formaldehyde.

Electromagnetic waves are the fourth largest source of pollution following water, noise, air pollution, including natural and artificial electromagnetic waves. It has been verified that the world health organization has long demonstrated five major effects of electromagnetic radiation on the human body: electromagnetic radiation is a major cause of diabetes, cancer mutations, cardiovascular disease; electromagnetic radiation can cause direct damage to the human genetic system, immune system and nervous system; the electromagnetic radiation is the inducing factor of the pathological changes of teratocarcinosis, pregnant woman sterility, abortion, etc.; in addition, excessive electromagnetic radiation can directly affect the skeletal development and the tissue development of children, and cause the decrease of liver hematopoietic function and vision, and the retinal detachment of serious people can be caused; electromagnetic radiation can also cause female endocrine disorders, menstrual disorders, decline of male reproductive function, and the like.

At present, there are two methods for developing anti-electromagnetic radiation fabric by adopting textile functional finishing: one is to plate metal on the fabric, and the conductivity of the plated metal directly influences the shielding effect of the fabric; the other method is electromagnetic shielding coating finishing of the fabric, namely adding dispersed electromagnetic wave absorbent into a coating agent, and then forming a film containing the electromagnetic wave absorbent on the surface of the fabric through coating finishing.

The ethylene urea can generate chemical reaction with formaldehyde at normal temperature, two imino groups in the ethylene urea and carbonyl groups in the formaldehyde generate Mannich reaction to generate Mannich base, and the product is stable and does not release aldehydes. The diatomite is a loose and light mineral material with a special porous structure, has stronger water absorption and better permeability and is used for enriching the indoor formaldehyde. The combination of the reactive formaldehyde removing agent and the adsorption formaldehyde catching agent is one of effective ways for improving the formaldehyde purification function of the material.

The graphene is formed by the SP of carbon atoms ² The thickness of the formed honeycomb crystal film is only 0.335 nm. The graphene material has high conductivity, large specific surface area, light weight, flexibility and excellent mechanical property, and is an ideal electromagnetic shielding material.

The anti-radiation sun-shading composite fabric capable of removing formaldehyde is designed, can shade sun in the using process, and can purify indoor formaldehyde gas and prevent outdoor electromagnetic waves from entering a room, so that the health of indoor personnel is protected in an all-round manner.
