Abstract
The invention discloses a preparation technology for glass fiber cloth. The preparation technology for the glass fiber cloth comprises the following steps of: (1) grey cloth weaving: tidying the warp beams of a plurality of glass fiber grey yarns via a slurry tidying machine by a one-time arranging combing warping technology; (2) warp beam combining: mixing warp yarn and weft yarn, dipping sheet yarn into a slurry tank for dipping slurry after combination, causing the wet slurry yarn leaving from the slurry tank to lease to enter a hot drying area, drying the wet slurry yarn until the moisture content is less than or equal to 2%, and carrying out shaft weaving to obtain the grey cloth; (3) first-time thermal cleaning: burning organic matters, such as slurry on the glass fiber cloth to 0.2-0.4% from 2%; (4) second-time thermal cleaning: carrying out second-time thermal cleaning on the glass fiber cloth in a stuffy furnace; and (5) surface treatment: coating silane coupling agent onto the white grey cloth of the glass fiber subjected to the second-time thermal cleaning desizing, drying, trimming, detecting contents on line, and packaging and putting into storage according to the level. The glass fiber cloth disclosed by the invention has the excellent high temperature resistance performance and good ablation property, and the insulation grade of an electrotechnical product is improved.
Description
?
Technical field
The invention belongs to textile technology field, relate in particular to glass fabric, specifically a kind of preparation technology of glass fabric.
Background technology
Glass fibre is a kind of Inorganic Non-metallic Materials of excellent performance, and composition is silica, aluminium oxide, calcium oxide, boron oxide, magnesia, sodium oxide molybdena etc.It is take glass marble or discarded glass as raw material through high temperature melting, wire drawing, doff, the technique such as weave cotton cloth.Finally form various product.
Because glass fibre has good electrical insulation capability and heat-resisting quantity, be conducive to improve the class of insulation of electric product, increase the service life, can meet the specific (special) requirements of electric product, therefore electronic-grade glass fiber cloth has become one of main raw material(s) of copper-clad plate industry, being the product that fiberglass product is maximum at the art of electrical insulation consumption, is also that in current glass textiles, technical merit requires the highest product, and it is finally for the manufacture of printed circuit board (PCB).
China mainland is started late because of electronics industry, so Fiberglass Industry is also slower to the exploitation of 7628 cloth.Within 1984, fiberglass-based copper-clad plate total output is 5000-5500 tons, and the main former metric lattice of sheet material are 0.5-5mm, and plate is wide 1 meter, consume 3000-3400 tons of glass fabrics.
Nearly ten years, electronics, the electrical equipment industry of China have obtained high speed development, according to Chinese printing circuit employer's organization latest survey data in 2005, show: within 2005, national copper-clad plate total output is over 1.5 hundred million, wherein the glass substrate is 1.2 hundred million, demand to the high-grade electronic grade glass cloth of physique reaches 800,000,000 square metres, domestic breach is also very large, and country can only annual solve and spend a large amount of valuable foreign exchanges by import for this reason.
Summary of the invention
The object of the present invention is to provide a kind of preparation technology of glass fabric.
Purpose of the present invention can be achieved through the following technical solutions:
A kind of preparation technology of glass fabric, take the glass fibre raw yarn as raw material, described preparation technology comprises that grey cloth is weaved and axle, for the first time heat clean, for the second time heat clean, surface treatment, it is characterized in that,
(1) grey cloth is weaved: fabric width, mesh by prepared grey cloth distribute, and calculate the total radical of yarn for required warp-wise, by some glass fibre raw yarns by row's comb warping technology once, by the whole good warp beam of whole pulp grinder;
And axle (2): the warp thread that step (1) is obtained mixes with weft yarn, merges the rear panel yarn and immerses the stock tank soaking paste, and the wet pulp yarn leasing after slurry outlet groove enters hot baking zone, after hot-air seasoning yam surface film forming, enter cylinder and dry, cylinder is dried to moisture content≤2%, and axle is made into grey cloth;
(3) heat is cleaned for the first time: the grey cloth that step (2) is obtained enters the centrifuge for removing liquid high-temperature region by cloth-feeding device, carrying out heat for the first time cleans, grey cloth by the time be heated and be attached to sizing agent on glass fabric and slurry is most of therefore burns and lose, hot centrifuge for removing liquid by the organic matters such as slurry on glass fabric from 2% burning to 0.2～0.4%;
(4) heat is cleaned for the second time: will be wound on heatproof coreless rolls cloth rewinder roll through the Hot-cleaning machine glass-fiber-fabric that heat is cleaned after destarch for the first time, the glass fibre yardage roll is placed on the steel carriage to be put into cold stoking again and carries out heat for the second time and clean;
(5) surface treatment: the glass fibre grey cloth silane coating coupling agent on surface treating machine after the destarch of heat cleaning for the second time, drying, trimming the online composition that detects, pack warehouse-in by grade.
The cleaning temperature that heat is cleaned for the first time of described step (3) is 350-500 ℃, and in described step (4) heat cleaning for the second time, the cold stoking temperature is 430 ℃, and the time of smouldering is 50-70h.
Described surface treatment is: the glass fibre grey cloth through the secondary heat treatment destarch passes through surface treating machine, carry out the processing of silane coating, grey cloth first enters water scrubber by the disconnected hair left on cloth cover by the storage cloth holder, lousiness cleans up, wet cloth enters infrared circulating air drying tower and carries out the grey cloth oven dry, grey cloth after oven dry enters the steeping vat impregnation, the silane coupler glue prepares by pipeline input steeping vat in the preparation still, the cloth of dipping silane glue is controlled the adhesive liquid quantity on cloth by the pair roller squeezing roller, grey cloth after gluing enters next infrared circulating air drying tower glue is dried, grey cloth after oven dry enters the cloth glue spreader by the cloth gluing, cloth after gluing enters infrared circulating air baker makes the sclerosis of selvedge glue then enter the cloth edge cutter, the burr of grey cloth two ends are cut away, enter the storage cloth holder, again by after the check of online quality control instrument, entering wrap-up, to process, trimming, the yardage roll class wrapping warehouse-in of checking.
It is thermal source that described infrared circulating air drying tower adopts light diesel fuel and steam.
Beneficial effect of the present invention: preparation technology of the present invention is weaved by the former process of glass fibre grey cloth and axle, heat cleaning for the first time, heat cleaning for the second time and surface treatment five steps are prepared glass fabric, glass fabric has resistant to elevated temperatures excellent properties, have good ablation property, the class of insulation of electric product is improved.
