AI Technical Summary

Problems solved by technology

[0004] However, due to the high viscosity and high resilience of bromobutyl rubber, it is difficult to spin
Moreover, bromobutyl rubber is an elastomer with a low glass transition temperature and is easy to deform, so the fiber film obtained by electrospinning is difficult to self-support

Abstract

The present invention discloses an electrospinning and self-supporting brominated butyl rubber system, which comprises a brominated butyl rubber, a surfactant, an anti-sticking aid and a solvent, wherein the spinnability of the brominated butyl rubber is achieved by adding the surfactant, the self-supporting property of the fiber film is improved and the morphology of the brominated butyl rubber fiber film is improved by adding the anti-sticking aid so as to obtain the fiber film with characteristics of smooth surface and good morphology, and optionally the electrospinning and self-supportingbrominated butyl rubber system further comprises function auxiliary agents, such that the fiber film has functions of sterilization, electric conductivity and the like. According to the present invention, the electrospinning and self-supporting brominated butyl rubber system has advantages of simple components and easily available raw materials, can achieve the electrospinning, and can obtain theself-supporting brominated butyl rubber fiber film.

Description

technical field [0001] The invention relates to the field of electrospinning, in particular to the electrospinning of brominated butyl rubber, in particular to an electrospun and self-supporting brominated butyl rubber system. Background technique [0002] Electrospinning is a processing technology in which a polymer is drawn in a solution or molten state with an external high-voltage power supply, sprayed to form ultrafine fibers, and received by a splicing device. The method is simple, efficient, low-cost and widely applicable, and can be used to prepare films of nano-scale fibers or micron-scale fibers, and can be mass-produced industrially. [0003] Bromobutyl rubber (BIIR) is widely used in gas masks, masks, gloves and other protective products due to its good damping properties, low permeability, biological non-toxicity and good comprehensive properties. However, solid bromobutyl rubber lacks breathability, creates thermal stress on the user's skin, and cannot be used...
