Abstract
The invention provides a reinforcement yarn for an optical cable and a preparation method thereof, belonging to the technical field of optical cable materials. The reinforcement yarn for the optical cable is characterized by comprising 75-85wt% of ECR glass fiber yarn and 15-25wt% of EVA hot melt adhesive. The preparation method of the reinforcement yarn for the optical cable is characterized by comprising the following concrete steps: firstly, heating the EVA hot melt adhesive at 130 DEG C-180 DEG C for 1-2 hours for melting; secondly, putting the melted EVA hot melt adhesive in a thermostatic solution tank, the temperature of which is controlled at 110 DEG C-130 DEG C; putting the ECR glass fiber yarn in the thermostatic solution tank for soaking; molding the yarn by extrusion by a pulling and extruding mold; controlling the proportion by controlling the dimension of a mold cavity of the pulling and extruding mold; after water cooling and curing, drying the yarn with compressed air; and coiling the yarn into a cylindrical shape by a coiling machine. The invention has the advantages of easy manufacture, low cost, soft texture, convenient use and good mechanical property.
Description
Technical field
The invention provides a kind of reinforcement yarn for optical cable and preparation method thereof, belong to the cable material technical field.
Background technology
The silvalin of making the optical cable employing at present mainly contains two kinds.A kind of is polyester fibers and synthetic fiber yarn, and its advantage is that cost is low, and weak point is that tensile strength is low, and elastic modulus is low, and breaking elongation is big.Another kind is the aramid fiber yarn, and its advantage is a good mechanical properties, but that its weak point is a cost is too high.
Summary of the invention
The purpose of this invention is to provide a kind of easy manufacturing, cost is low, quality is soft, the reinforcement yarn for optical cable of easy to use and good mechanical performance and preparation method thereof.
In order to achieve the above object, technical scheme of the present invention provides a kind of reinforcement yarn for optical cable, it is characterized in that, is made up of ECR glass fiber yarn 75～85wt% and EVA hot melt adhesive 15～25wt%.
The present invention also provides the preparation method of above-mentioned reinforcement yarn for optical cable, it is characterized in that, concrete steps are:
The first step: the EVA hot melt adhesive was made its fusion in 1～2 hour 130 ℃～180 ℃ heating;
Second step: will be the EVA thermosol of fusion place temperature to be controlled in 110 ℃～130 ℃ the constant temperature solution tank, the ECR glass fiber yarn placed in the constant temperature solution tank it is soaked into, through pultrusion mould extrusion molding, by the size of control pultrusion mould die cavity, the control proportioning is solidified through water cooling, dry up with pressurized air, adopt the traction of frequency control drawing machine, 8～12 meters of control line speed per minutes adopt winder to be wound into tubular.
Principle of the present invention is as follows:
1, (ethylene-vinyl acetate copolymer, molecular formula are C to EVA
18H
3006X
2) hot melt adhesive at room temperature is generally solid, fusion is a liquid when being heated to a certain degree, in case be cooled to below the fusing point, becomes solid again rapidly.
2, adopt the thermoplastic composite technology, EVA hot melt adhesive and ECR glass fiber yarn bounding force are strong, are material of main part with the ECR glass fiber yarn, with the EVA hot melt adhesive compound after, have humidification.
3, the existing certain flexibility of EVA hot melt adhesive glue-line, again certain toughness arranged.With glass fibre bonding after, can satisfy pliability requirement to compound.
Advantage of the present invention is:
1, density is low, the tensile strength height, and elastic modulus is big, and breaking elongation is low.Its tensile strength is polyester fibers and synthetic fiber yarn 2～3 times, elastic modulus is greater than 72GPa, and breaking elongation is less than 1/6 of polyester fibers, synthetic fiber yarn, existing certain flexibility, certain toughness is arranged again, satisfy optical cable fully strengthening the requirement of yarn technical feature.
2, cost is low, and is close with polyester fibers, synthetic fiber yarn, is about 10% of aramid fiber yarn.
3, easily make, highly efficient in productivity.
4, use reinforcement yarn of the present invention to substitute original reinforcement yarn, very convenient, use existing equipment and existing technology to get final product.
