Embodiment 1

[0030] The preparation technology of rubber composite fiber comprises the following steps:

[0031] Add 30g of butyl rubber into 300ml of n-heptane, swell at room temperature for 15 hours to obtain butyl rubber sol, then add 10g of zinc nitrate and stir to mix evenly, and then pass in chlorine gas for 8 minutes for chlorination. The sodium solution was neutralized to pH=10, then rinsed with deionized water to pH=7, then 50g of polyester fiber and 500g of n-heptane were added to the glue, stirred and mixed for 12 hours to obtain fiber glue, and then added to the fiber glue Add 0.3g of sulfur and 0.3g of anti-aging agent DNP[N,N'-bis(β-naphthyl)-p-phenylenediamine], stir and mix evenly to obtain a composite glue.

[0032] Inject the composite glue into the electrospinning machine, set the voltage to 30kV, the propulsion speed to 0.05mm / s, and the receiving distance to 20cm. The fibers are collected on the grounded aluminum foil for electrospinning. The ambient temperature at the...

Embodiment 2

[0034] The preparation technology of rubber composite fiber comprises the following steps:

[0035] Add 30g of butyl rubber into 300ml of n-octane, swell at room temperature for 12 hours to obtain butyl rubber sol, then add 10g of zinc nitrate and stir to mix evenly, and then pass chlorine gas for 5 minutes for chlorination. The sodium solution was neutralized to pH=10, then rinsed with deionized water to pH=7, then 50g of polyester fiber and 500g of n-octane were added to the glue, stirred and mixed for 8 hours to obtain the fiber glue, and then added to the fiber glue Add 0.2g sodium dithiocarbamate, 0.06g ammonium dithiocarbamate, 0.7g anti-aging agent DNP[N,N'-bis(β-naphthyl)-p-phenylenediamine], stir and mix evenly to obtain composite glue liquid.

[0036] Inject the composite glue into the electrospinning machine, set the voltage to 30kV, the propulsion speed to 0.05mm / s, and the receiving distance to 20cm. The fibers are collected on the grounded aluminum foil for elec...

Abstract

The invention discloses a rubber composite fiber and a preparation process of the rubber composite fiber. The rubber composite fiber comprises polyester fibers and chlorinated butyl rubber, wherein the polyester fibers are wrapped in the chlorinated butyl rubber, the length of the polyester fibers is 50-100 [mu] m, and the diameter of the polyester fibers is 5-15 [mu] m. The defects in the prior art are overcome, with the process and formula, the strength and elongation of the rubber composite fiber are effectively enhanced, and meanwhile, the aging resistance and flame retardancy of the rubber composite fiber are improved.

Description

technical field [0001] The invention relates to the technical field of rubber composite fibers, in particular to a rubber composite fiber and a preparation process thereof. Background technique [0002] Both rubber and chemical fiber are important chemical materials in this century, and are widely used in aerospace and people's daily life. Due to its excellent elasticity, thermal stability, aging resistance, corrosion resistance, water resistance, insulation and other properties, rubber is widely used in many fields such as automobile parts, wires and cables, and seals. Due to its excellent mechanical properties, thermal stability, aging resistance, corrosion resistance, water resistance, insulation and other properties, chemical fibers are widely used in packaging, clothing and other fields, but chemical fibers do not have the elasticity of rubber, and rubber does not have the strength of chemical fibers, so , the application of chemical fibers in the field of stretchable ...
