Embodiment 1

[0013] The production process of high-strength FRP reinforced core includes the steps of yarn unwinding, yarn guiding, dipping, heating and curing, traction and winding in sequence. Strands of glass yarn, and then enter the dipping tank for impregnation, the dipping liquid in the dipping tank includes 100kg of vinyl resin, 3kg of curing agent, 3kg of release agent and 10kg of filler, and then enter the heating mold for heating Curing, using low, medium and high temperature step-by-step curing method, the curing agent uses low-temperature curing agent di-tert-butylcyclohexyl peroxide dicarbonate, medium-temperature curing agent dibenzoyl peroxide, high-temperature curing agent tert-butyl peroxybenzoate, heating The mold is divided into three temperature zones of low, medium and high according to the curing temperature, which are 120°C, 140°C and 160°C respectively. The initial mold temperature is selected as 110°C. Finished product winding, glass yarn enters the traction speed ...

Embodiment 2

[0016] The production process of high-strength FRP reinforced core includes the steps of yarn unwinding, yarn guiding, dipping, heating and curing, traction and winding in sequence. Strands of glass yarn, and then enter the dipping tank for impregnation, the dipping liquid in the dipping tank includes 100kg of vinyl resin, 4kg of curing agent, 3.5kg of release agent and 15kg of filler, and then enter the heating mold for heating Curing, using low, medium and high temperature step-by-step curing method, the curing agent uses low-temperature curing agent di-tert-butylcyclohexyl peroxide dicarbonate, medium-temperature curing agent dibenzoyl peroxide, high-temperature curing agent tert-butyl peroxybenzoate, heating The mold is divided into three temperature zones of low, medium and high according to the curing temperature, which are 120°C, 145°C and 165°C respectively. The initial mold temperature is selected as 115°C. Finished product winding, glass yarn enters the traction spee...

Abstract

A disclosed production technology for a high-strength FRP reinforced core successively comprises steps of releasing yarn, guiding yarn, immersing, heat-curing, dragging and coiling; and specifically comprises: carrying out releasing yarn and guiding yarn for a glass fibre, then immersing in an immersion groove in which the immersion liquid comprises vinyl resin, curing agents, a mold lubricant and a filling material; placing in a heating die, heat curing by employing a low-medium-high temperature step progressive curing mode, then pulling the heat-cured glass yarn from the heating die via a dragger, and carrying out finished-product coiling. The curing agents ocmprise a low-temperature curing agent bis(4-t-butyl cyclohexyl)peroxy dicarbonate, a medium-temperature curing agent dibenzoyl peroxide and a high-temperature curing agent t-butyl peroxybenzoate; and the heating die is divided into three temperature zones according to the curing temperature, and the initial temperature of the die is 110-120 DEG C. The advantages are that: by employing low-temperature, medium-temperature and high-temperature three curing agents for the low-medium-high temperature step progressive curing mode, the rigidity and the toughness are integrated, the high strength and the good pull resistance are guaranteed.

Description

technical field [0001] The invention relates to a production process of a high-strength FRP reinforcing core, which belongs to the field of communication optical cables. Background technique [0002] The tensile strength of the FRP fiber optic cable reinforcement core is ≥1100Mpa in the industry standard, while the high-strength reinforcement cores of ≥1300Mpa used in the communication optical cable industry generally rely on imports. The rigidity and toughness of ordinary optical cables are not uniform, and the strength is not high. General pull. Therefore, it is necessary to provide a new technical solution to solve the above problems. Contents of the invention [0003] The purpose of the invention is to provide a high-strength FRP reinforced core production process. It solves the problem that the rigidity and toughness of ordinary optical cables are not uniform, and the strength is not high. [0004] In order to achieve the above object, the technical scheme adopted ...
