Anti-radiation composite thermal insulation fabric and preparation method thereof

Abstract

The invention discloses an anti-radiation composite thermal insulation fabric and a preparation method thereof. The preparation method comprises the following steps of firstly, introducing cucurbit urils into aerogel to form modified aerogel, mixing the modified aerogel into a negative ion fiber spinning solution to prepare a fiber base material, modifying the fiber base material by virtue of a first modification solution and a second modification solution, and generating a compact metal film and a high-conductivity long chain on the fiber base material, so as to obtain modified fibers; takingthe modified fiber as a core layer; and taking polygonum multiflorum fibers and silk fibers as an outer wrapping layer to prepare the anti-radiation heat preservation composite fabric. The fabric prepared by the invention not only has an excellent anti-radiation effect, but also has relatively high bacteriostatic and antibacterial properties, and after 50 times of washing, the anti-radiation ability and bacteriostatic and antibacterial ability are not obviously changed, and the washing-resistant effect is remarkable.

Description

technical field [0001] The invention relates to the technical field of fabrics, in particular to a radiation-proof composite thermal insulation fabric and a preparation method thereof. Background technique [0002] While the development of science and technology brings convenience to people's lives, the use of various electronic devices also brings electromagnetic radiation pollution to people; electromagnetic radiation pollution is different from traditional water pollution, noise pollution, and air pollution. It is invisible and intangible, and it will not make people feel any abnormality in a short period of time, but if people are exposed to electromagnetic radiation for a long time, it will seriously endanger the physical and mental health of the human body, especially for the elderly, pregnant women, and children with weak constitutions; Radiation can affect children's intellectual development, bone development, and cause problems such as decreased immunity.

[0002] While the development of science and technology brings convenience to people's lives, the use of various electronic devices also brings electromagnetic radiation pollution to people; electromagnetic radiation pollution is different from traditional water pollution, noise pollution, and air pollution. It is invisible and intangible, and it will not make people feel any abnormality in a short period of time, but if people are exposed to electromagnetic radiation for a long time, it will seriously endanger the physical and mental health of the human body, especially for the elderly, pregnant women, and children with weak constitutions; Radiation can affect children's intellectual development, bone development, and cause problems such as decreased immunity

[0003] The preparation methods of anti-radiation fabrics on the market mainly include (1) plating a metal layer on the surface of the fabric. The bonding between the fabric and the metal layer is not strong enough, and it is easy to cause the metal layer to fall off during daily washing and use, causing electromagnetic waves. The shielding effect is reduced; (2) the conductive fiber is blended with ordinary fibers, and the fabric prepared by this method needs to be hung vertically and cannot be folded to prevent fiber breakage from affecting the electromagnetic shielding effect; (3) the surface of the fabric is coated with a metal coating, and the fabric Poor hand feeling, airtight, and not resistant to washing; the antibacterial properties of the anti-radiation fabrics prepared by the prior art also need to be further improved
