Problems solved by technology

[0003] Ultraviolet radiation is more harmful to the human body. The human body is exposed to ultraviolet radiation for a long time, which is prone to skin diseases and eventually induces skin cancer. Ultraviolet radiation can also accelerate the decomposition and aging of organic and inorganic materials, and can accelerate the aging speed of polymers. Discoloration of dyes, etc., and then changes in the properties of materials, ultraviolet radiation can also cause damage to the growth and development of plants, so it is particularly important to invent a radiation-proof and heat-insulating fabric and its preparation method

Abstract

The invention discloses an anti-radiation heat-insulation fabric and a preparation method thereof. The anti-radiation heat-insulation fabric is prepared from a fabric and a modified polyurethane coating coated on the surface of the fabric; the fabric is formed by weaving linen fibers; the modified polyurethane coating is prepared from the following raw materials in parts by weight: 15-20 parts of isophorone diisocyanate, 30-40 parts of polycaprolactone diol, 3-4 parts of dimethylolpropionic acid, 0.5-1 part of a catalyst and 2-3 parts of trimethylolpropane; the modified polyurethane coating further comprises a flame retardant and an ultraviolet light absorber; the ultraviolet light absorber is prepared from resorcinol, trichlorotoluene and a solvent; the flame retardant is prepared from phenol, phosphorus oxychloride, a catalyst and anhydrous aluminum trichloride; and the solvent is toluene. On the basis of an original linen fiber fabric, the modified polyurethane coating is added on the linen fiber fabric through a padding process, and the added modified polyurethane coating can improve the mechanical strength and the anti-radiation performance of the product fabric.

Description

technical field [0001] The invention relates to the technical field of fabric preparation, in particular to a radiation-proof and heat-insulating fabric and a preparation method thereof. Background technique [0002] The wavelength range of ultraviolet radiation is 40-400nm. Generally, ultraviolet wavelengths are divided into A band: 320-400nm, B band 280-320nm, C band: 200-280nm, vacuum ultraviolet band 10-200nm, and ultraviolet rays with a wavelength less than 200nm will It is absorbed by the atmosphere and cannot be transmitted, and the ozone layer can absorb solar radiation substances with a wavelength of less than 300nm. Therefore, in the current ultraviolet protection, the main anti-ultraviolet radiation has a wavelength between 290-400nm. [0003] Ultraviolet radiation is more harmful to the human body. The human body is exposed to ultraviolet radiation for a long time, which is prone to skin diseases and eventually induces skin cancer. Ultraviolet radiation can also ...
