Abstract
Disclosed is a novel processing technology of a glass fiber composite insulating rod. According to the novel processing technology, glass fiber is heated to 60-70 DEG C, and when the glass fiber enters a steeping vat again for impregnation, minute air bubbles in a glue solution can float upwards by heating so as to minimize bubbles during the impregnation process of the glass fiber and raise the 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 the formation production glass fibre compound inslation rod of leaving behind continuously.Because glass fibre is through steeping vat the time; It is impregnation under atmospheric pressure state; Glass fiber dipped not passing through and entrained bubbles taken place easily; The insulating bar that causes the producing quality that ruptures easily is unreliable, and the glue in the steeping vat be by multiple material mix become, production technology has ageing requirement to the glue in the steeping vat.
Summary of the invention
In the production technology that overcomes existing glass fiber composite insulating bar; Glass fiber dipped not passing through and the deficiency of entrained bubbles; The present invention provides a kind of novel processing technology of glass fibre compound inslation rod; The novel processing technology of this glass fibre compound inslation rod has improved existing technology, can overcome above-mentioned shortcoming well.
The technical solution adopted for the present invention to solve the technical problems is: the novel 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 forms glue; Glass fibre to be processed is dry, and processing technology comprises the following steps:
(1), glass fibre is through getting in the heater behind the spreader, the temperature in the heater is controlled at 60 ℃ to 70 ℃;
(2), get into impregnation in the steeping vat through the glass fibre behind the heater;
(3), the glass fibre behind the impregnation is through the preformed of pressure distribution device;
(4), the Fiber glass rod after the preformed gets in the shaper and is heating and curing; Solidify to adopt and divide 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 ℃;
(5), after the products solidifying of waiting the to finalize the design cooling, cut, become finished product.
The invention has the beneficial effects as follows; Glass fibre is heated to 60 ℃ to 70 ℃, when glass fibre gets in the steeping vat impregnation again, can be with the air minute bubbles heating come-up that contains in the glue; Reduce glass fibre entrained bubbles in immersing glue process, improved the quality of product.
The specific embodiment
In the novel 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 forms glue, and glass fibre to be processed is dry, and processing technology comprises the following steps:
(1), glass fibre is through getting in the heater behind the spreader, the temperature in the heater is controlled at 60 ℃ to 70 ℃;
(2), get into impregnation in the steeping vat through the glass fibre behind the heater;
(3), the glass fibre behind the impregnation is through the preformed of pressure distribution device;
(4), the Fiber glass rod after the preformed gets in the shaper and is heating and curing; Solidify to adopt and divide 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 ℃;
(5), after the products solidifying of waiting the to finalize the design cooling, cut, become finished product.
In the present embodiment, resin is a Bisphenol F type epoxy, and curing agent is a methyl tetrahydrophthalic anhydride, and promoter is adopted DMP-30 promoter.
