Description
Technical field
The invention belongs to the preparation technical field of glass fabric, in particular to a kind of super-thin electronic grade fiberglass cloth
Manufacturing technique method.
Background technique
Electron glass fiber cloth is formed by electronic-grade glass weaving yarns, and destarch, smoldering, upper inorganic agent are then passed through
Link forms completed electronic grade fiberglass cloth.The common thin cloth kind of batch is 1080 cloth, grammes per square metre 47.5g/ currently on the market
㎡, thickness 0.050mm.With the development of science and technology the direction of each electronic product towards " light, small, thin " is developed.Corresponding copper-clad plate
A kind of ultra-thin electronic-grade glass fiber cloth of producer's demand.
Have following technical barrier needs to capture in thin cloth production process: 1. the yarn of thin cloth is thin, warp beam during whole slurry
Tension is difficult control uniformly, and so as to cause face tension unevenness, the unusual condition of cloth cover injustice occurs in finished fabric.2. desizing processes
The bad grasp of the control of middle temperature and time, the low desizing of temperature are not thorough, and are caused PP sector-meeting generation " fish mesh " bad, are caused to drop
Grade；Temperature is high, and the time is long, then thin cloth smoldering can be caused excessively saturating because of cloth is thin, generation tearing, intensity situation not up to standard.3. selecting
The weaving process for selecting a kind of cloth also thinner than 1080 cloth is relatively difficult, must select suitable yarn kind and thread count group appropriate
It closes.
A kind of super-thin electronic grade fiberglass cloth is needed now, to adapt to the requirement of downstream client, meets the needs in market.
Summary of the invention
In view of the deficiencies of the prior art, the object of the present invention is to provide a kind of production works of super-thin electronic grade fiberglass cloth
Process, scientific and reasonable, simple and easy, glass fabric tearing strength obtained is high, and face tension is uniform.
The manufacturing technique method of super-thin electronic grade fiberglass cloth of the present invention, comprising the following steps:
1) in electronic-grade glass yarn production process, starching processing is carried out, is uniformly applied slurry by starching machine
It is put on every one thread, then even tension is wound on a beam, and carries out whole slurry；
2) by the warp beam starched on air-jet loom machine, the picking on air-jet loom machine, different thread counts interweave and
At glass fibre fabric；
3) pass through the continuous desizing of KH, the slurry of burn off 85-95%, for the second time by the smoldering of BH furnace, by the residual slurry rate of glass-fiber-fabric
Fall back on 0.08% or less；
4) silane surface coupling agent treatment is carried out to glass fabric again after desizing, obtains required electronic-grade glass
Finished fabric.
In the step 2, through using D450 yarn to yarn, broadwise uses D900 yarn with yarn；Thread count technique uses
(44 ± 1) × (34 ± 1) root/in.
In the step 2, the fabric woven is 24.2-26.2g/m2, with a thickness of 0.025-0.031mm.
In the step 2, the precision of electronic tensile device is accurate to 0.1N in air-jet loom machine；Every yarn in production process
Between tension difference value < 0.3N.
In the step 3, in the continuous desizing processes of KH, speed of service 47-53m/min, temperature 375-385
DEG C, the residual slurry rate control of the KH cloth produced is between 0.25-0.30%.
In the step 3, in the controlling unit of smoldering BH, smoldering temperature is 390-410 DEG C, and the smoldering time is 62 small
When.
In the step 4, silane surface coupling agent is 168S, is Shanghai Ya Fu Chemical Co., Ltd..
Compared with prior art, the invention has the following beneficial effects:
1. the tension force of warp beam is uniform during whole slurry, so that face tension is uniform；Woven cloths rational technology, than commercially available
The thin 0.022mm of product, the light 20.8g/m of base weight2；
2. electron glass fiber cloth made from has tearing strength high；Cloth cover is smooth, ultra-thin characteristic；
3. manufacturing technique method described in is scientific and reasonable, simple and easy.
