Abstract

The invention discloses a preparation method of PTT (polytrimethylene terephthalate) fabric for ray protection and protective fabric, and relates to the field of radiation protection equipment, the preparation method comprises the following steps: mixing: adding bismuth powder and boron powder into a PEO (polyethylene oxide) 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; performing melt spinning: blending the surface modified composite powder and PTT resin according to a ratio of (7-8): (2-3), performing granulation, and performing melt spinning to obtain modified powder fibers; and molding: spreading or interweaving the modified powder fibers and metal wires to obtain the PTT fabric for neutron / gamma ray protection. The invention has the advantages that the PTT resin with excellent performance is used as a substrate material to prepare the modified powder fiber, and the prepared protective fabric has an integrated protective function, and is light in weight, good in air permeability, good in elasticity and easy to process.

Description

technical field [0001] The invention relates to the field of radiation protection equipment, in particular to a preparation method of a PTT fabric for radiation protection and a protective fabric. Background technique [0002] While promoting the rapid development of national defense and medical fields, traditional fossil energy also causes environmental pollution, greenhouse effect and many other unfavorable factors. In order to get rid of the dependence on traditional fossil energy, more and more fields use nuclear energy as the preferred energy supply method. While nuclear energy provides clean energy, its associated neutron / gamma rays not only pollute the environment and damage equipment, but also easily penetrate the human body, causing cell mutation in the human body and threatening life safety. Therefore, it is urgent to develop neutron / gamma ray protective materials. [0003] The prior art methods for preparing neutron protection composite materials include hot pre...
