Embodiment 1

[0029] A method for preparing a glass fiber optic cable reinforcing core, comprising the following steps, the reinforcing core is formed by coating the glass fiber with glue and curing, wherein the glue contains 60% matrix resin, 2% dibenzoyl peroxide, 5% tert-butyl peroxybenzoate, 5% mold release agent and 28% filler, wherein the filler includes 30% heavy calcium and 70% aluminum hydroxide, and the glue is heated to 200°C and filled into Coating device, the glass fiber is coated with glue through the coating device, enters the drying device from the cavity of the mold for curing, and then dips into the detection device to detect the surface finish of the reinforcing core, and finally 0.5-1m / The speed of s is uniform to take up the line. In addition, when the reinforcing core passes through the drying device, the reinforcing core is first dried quickly at 340°C to cure the surface first, and then quickly blown with hot air at 290°C to make it fully cured.

Embodiment 2

[0031] A method for preparing a glass fiber optic cable reinforcement core, comprising the following steps, the reinforcement core is formed by coating the glass fiber with glue and curing, wherein the glue contains 80% matrix resin, 1% dibenzoyl peroxide, 5% tert-butyl peroxybenzoate, 6% mold release agent and 8% filler, wherein the filler includes 70% heavy calcium and 30% aluminum hydroxide, and the glue solution is heated to 200°C and filled into Coating device, the glass fiber is coated with glue through the coating device, enters the drying device from the mold cavity for curing, and then dips into the detection device to detect the surface finish of the reinforcing core, and finally Take up the line at a constant speed. In addition, when the reinforcement core passes through the drying device, the reinforcement core is first dried quickly at 360°C to cure the surface first, and then quickly blown by 310°C hot air to make it fully cured.

Embodiment 3

[0033] A method for preparing a glass fiber optic cable reinforcing core, comprising the following steps, the reinforcing core is formed by coating the glass fiber with glue and curing, wherein the glue contains 70% matrix resin, 3% dibenzoyl peroxide, 6% tert-butyl peroxybenzoate, 6% release agent and 15% filler, wherein the filler includes 30% heavy calcium and 70% aluminum hydroxide, and the glue is heated to 200°C and filled into Coating device, the glass fiber is coated with glue through the coating device, enters the drying device from the mold cavity for curing, and then dips into the detection device to detect the surface smoothness of the reinforcing core, and finally with a rate of 0.5 / s Take up the line at a constant speed. In addition, when the reinforcing core passes through the drying device, the reinforcing core is first dried quickly at 350°C to cure the surface first, and then quickly blown by 300°C hot air to make it fully cured.

Abstract

The invention discloses a preparation method of a glass fiber optical cable reinforcing core. The preparation method comprises the following steps that reinforcing core is formed by coating the glassfibers through glue solution wherein the glue solution comprises 60-80% of matrix resin, 1-3% of dibenzoyl peroxide, 5-6% of tert-butyl peroxybenzoate and 5-6% of a release agent and 8-28% of a filler, wherein the filler is composed of 30-70% of heavy calcium and 30-70% of aluminum hydroxide; and the glue solution is heated to 200 DEG C and then is filled into a coating device, wire paying-off ofglass fiber is carried out at a constant speed by a wire paying-off device, glue solution coating is carried out through the coating device, then the glass fiber enters a drying device from a mold hole of the mold to be solidified, and then enters a detection device to detect surface cleanness degree of the reinforcing core, and finally wire taking-up is carried out at the constant speed with 0.5-1 m / s. The glass fiber optical cable reinforcing core prepared by adopting the preparation technology and the raw material ratio has the advantages of being light in weight, high in strength, resistant to stretching and the like; and matching equipment controls the running speed through the detection device, so that the quality of products is ensured, and the glue solution coating is more uniform.

Description

technical field [0001] The invention relates to the production field of glass fiber optic cable reinforcement cores, in particular to a preparation method of glass fiber optic cable reinforcement cores. Background technique [0002] In order to make the optical cable less prone to damage, a strengthening core is added to the optical cable to increase the strength of the optical cable. There are many types of fiber optic cable strength cores, which can be divided into metal fiber optic cable strength cores and non-metal fiber optic cable strength cores. The traditional metal optical cable strengthening core is generally steel wire. Because the conductivity and activity of the metal will interfere with the optical fiber communication in the optical cable and it is easy to corrode and has a short service life. Therefore, a corrosion-resistant, non-conductive, long service life, and Optical cable strength core material that does not interfere with optical fiber communication. ...
