Problems solved by technology

[0004] When the existing protective materials are made into protective clothing, it is difficult to process itself and the bonding force between different materials is not strong, resulting in complicated processing technology and high processing costs. At the same time, the protective clothing made usually has poor air permeability and heat resistance. Defects and other problems affect the wearing comfort

Abstract

The invention discloses a preparation method of a PET fabric for ray protection and a protective fabric, and relates to the field of radiation protection, and the preparation method comprises the following steps: mixing: adding bismuth powder and boron powder into a PEO aqueous solution according to a ratio of (2-5): (5-8), and mixing to obtain composite powder; surface modification: carrying out surface modification on the composite powder and a silane coupling agent octa (aminophenyl trioxosilane) according to a ratio of (80-100): 1 to obtain surface modified composite powder; melting and filament making: blending the surface modified composite powder and PET resin according to a ratio of (7-8): (2-3), granulating, melting and shredding to obtain modified powder fibers; forming: paving or interweaving the modified powder fibers and metal wires to obtain the PET fabric for neutron / gamma ray protection. The protective fabric has the advantages that the PET resin with excellent performance is used as a substrate material, the modified powder fibers are prepared in a film forming and shredding mode, and the prepared protective fabric has an integrated protective function and has good heat resistance, mechanical strength and air permeability.

Description

technical field [0001] The invention relates to the field of radiation protection, in particular to a preparation method of a PET fabric for radiation protection and the protective fabric. Background technique [0002] In recent years, nuclear radiation has been widely used in many fields such as industrial flaw detection, life treatment and environmental detection. However, unreasonable use of nuclear rays will pollute the environment, damage equipment and even threaten life and health. For this reason, radiation protection materials should be prepared as soon as possible while nuclear energy is used rationally. [0003] In the prior art, radiation shielding materials are usually made of two or more materials. For example, the Chinese invention patent (CN107555850A) discloses a composite material for neutron radiation protection and its preparation method. In this method, neutron absorbing materials, metal particles and binders are organically combined. First, the metal p...
