Abstract
The present invention discloses a processing technology for a glass fiber composite insulation rod. According to the processing technology, vacuum pumping is performed on the upper portion of a glue dipping tank, such that air in a glue liquid in the dipping tank floats, and bubbles entrained by glass fibers during a glue dipping process are reduced; and the glass fibers pass through the freshly prepared glue liquid during glue dipping in a glue dipping chamber so as to meet timeliness requirements on the glue liquid and improve product quality.
Description
Technical field
The present invention relates to a kind of processing technology of glass fibre compound inslation rod.
Background technology
At present, glass fibre behind the impregnation, is heating and curing through mould in the steeping vat of normal pressure, is squeezing continuously the formation production glass fibre compound inslation rod of leaving behind.Because glass fibre is through steeping vat the time, it is impregnation under atmospheric pressure state, easily occur glass fiber dipped not thoroughly and carry bubble secretly, the insulating bar that causes the producing quality that easily ruptures is unreliable, and the glue in the steeping vat is become by the many kinds of substance mixing, and production technology has ageing requirement to the glue in the steeping vat.
Summary of the invention
In the production technology that overcomes existing glass fibre compound inslation rod, glass fiber dipped glue not saturating, that carry bubble, impregnation secretly is not the deficiency of the glue of instant proportioning, the invention provides a kind of processing technology of glass fibre compound inslation rod, the processing technology of this glass fibre compound inslation rod has been improved existing technique, can overcome well above-mentioned shortcoming.
The technical solution adopted for the present invention to solve the technical problems is: the processing technology of glass fibre compound inslation rod, each raw material of glue by weight, 55% to 65% resin, 5% to 15% reinforcing agent, 5% to 15% promoter and 15% to 25% curing agent mix and form glue, glass fibre to be processed is dry, and processing technology comprises the following steps:
(1), glue is positioned in the steeping vat, then steeping vat is airtight after, vacuumize in the steeping vat above glue, the low vacuum in the steeping vat is opened steeping vat and is communicated with outside air behind 0.5 atmospheric pressure;
(2), the glass fibre through spreader enters impregnation in the steeping vat;
(3), to enter impregnation through the glass fibre of steeping vat indoor, glass fibre is passed in the glue of instant proportioning in the impregnation chamber;
(4), pass the glass fibre of impregnation chamber through the preformed of pressure distribution device;
(5), the Fiber glass rod after the preformed enters in the shaper and is heating and curing; Solidify and adopt a minute three phases to be heating and curing, the phase I warm-up phase, temperature is controlled at 80 ℃ to 120 ℃; In the second stage gelling stage, temperature is controlled at 120 ℃ to 150 ℃; Phase III cure stage, temperature are controlled at 150 ℃ to 190 ℃;
(6), after the products solidifying cooling of finalizing the design, cut, become finished product.
In this processing technology, the steeping vat top in step (1) vacuumizes, so that the floating of the glue Air in the steeping vat reduces glass fibre and carry bubble secretly in immersing glue process; In the step (3), glass fibre passes the glue of instant proportioning, has fully satisfied the requirement ageing to glue.
The invention has the beneficial effects as follows, vacuumize on steeping vat top, so that the air that contains in the glue in steeping vat floating reduces glass fibre and carry bubble secretly in immersing glue process; Glass fibre passes the glue of instant proportioning during impregnation in the impregnation chamber, fully satisfied the requirement ageing to glue, has improved the quality of product.
The specific embodiment
In the processing technology of glass fibre compound inslation rod, each raw material of glue by weight, 60% resin, 10% reinforcing agent, 10% promoter and 20% curing agent mix and form glue, glass fibre to be processed is dry, and processing technology comprises the following steps:
(1), glue is positioned in the steeping vat, then steeping vat is airtight after, vacuumize in the steeping vat above glue, the low vacuum in the steeping vat is opened steeping vat and is communicated with outside air behind 0.1 atmospheric pressure;
(2), the glass fibre through spreader enters impregnation in the steeping vat;
(3), to enter impregnation through the glass fibre of steeping vat indoor, glass fibre is passed in the glue of instant proportioning in the impregnation chamber;
(4), pass the glass fibre of impregnation chamber through the preformed of pressure distribution device;
(5), the Fiber glass rod after the preformed enters in the shaper and is heating and curing; Solidify and adopt a minute three phases to be heating and curing, the phase I warm-up phase, temperature is controlled at 80 ℃ to 120 ℃; In the second stage gelling stage, temperature is controlled at 120 ℃ to 150 ℃; Phase III cure stage, temperature are controlled at 150 ℃ to 190 ℃;
(6), after the products solidifying cooling of finalizing the design, cut, become finished product.
In the present embodiment, resin is Bisphenol F type epoxy, and curing agent is methyl tetrahydrophthalic anhydride, and promoter is adopted DMP-30 promoter.
