Embodiment 1

[0021] Such as figure 1 A non-metallic reinforcing member as shown comprises a glass fiber 1 arranged in the center and a carbon-bonded non-metallic bonding layer 2 coated outside the glass fiber 1, the cross section of which is circular, and its preparation method comprises steps

[0022] (1) Feed: first place the glass fiber of the corresponding specification on the pay-off rack, pass the lead wire through a mold with a hole diameter of 0.50mm, a length of 480mm and a width of 200mm, bypass the traction, tighten the wire and fix it on the plastic disk;

[0023] (2) Soaking: Immerse the glass fiber in the impregnating solution for 10-20 minutes. The impregnating solution is prepared from the following components in weight percent: graphite 3.8%, resin 18%, calcium carbonate 6.5%, stearic acid 8.5% zinc, 16.2% aluminum hydroxide, 8.5% sulphate, 9.2% PE powder, 12% release agent, 17.3% resin sizing agent;

[0024] (3) Drying / curing: introduce the glass fiber into the mold at a...

Abstract

The invention discloses a preparation method of a non-metal reinforcer. The preparation method includes the steps that silk is taken; soaking is carried out, wherein glass fibers are soaked in soakingliquid for 10-20 min, and the soaking liquid is prepared from, by weight, 3.8% of graphite, 18% of resin, 6.5% of calcium carbonate, 8.5% of zinc stearate, 16.2% of aluminium hydroxide, 8.5% of Suding ester, 9.2% of PE powder, 12% of release agent and 17.3% of resin impregnating compound; drying / curing is carried out, wherein the glass fibers are introduced into a die, the speed is 5 m / min, the glass fibers are dried by the die, and the soaking liquid on the surfaces of the glass fibers is cured into a carbon alloy non-metal bonding layer; extruding and pulling are carried out, wherein the glass fibers coated with the carbon alloy non-metal bonding layer are pulled out of a bush die through an extruding and pulling machine.

Description

technical field [0001] The invention relates to a preparation method of an optical cable strengthening member, in particular to a preparation method of a non-metallic optical cable strengthening member. Background technique [0002] Many cables, such as fiber optic cables, generally include a strength member comprising at least one fiber or bundle of fibers. The reinforcement typically comprises one or more of glass fibers, aramid fibers, carbon fibers, etc. in a polymer matrix of epoxy, polyester, vinyl ester, polyolefin, acrylic, etc. Fiber and polymer selection is based on the desired characteristics of the reinforcement including, but not limited to, modulus of elasticity, tensile strength, and coefficient of thermal expansion. [0003] One method of making reinforcements is resin-wetting enabled pultrusion (resin-wetting enabled [0004] pultrusion). The method comprises the steps of wetting the fibers in a resin bath followed by consolidating the resin on the fibers...
