Description
Technical field
The present invention relates to a kind of warp thread secondary slurry that is applied to the electronic-grade glass fiber cloth technical field.
Background technology
Electronic-grade glass fiber cloth is formed by the electronic-grade glass weaving yarns, as the electronic-grade glass yarn (E-glass) of weaving cotton cloth, is a kind of aluminoborosilicate material, promptly by SiO
2, Al
2O
3, B
2O
3Constitute the master network skeleton, MgO, CaO is as the inorganic insulator of network filler.Its manufacturing technique is with the silicon yarn, bechilite, and stone rues, ores such as lime stone mix fusion and are eutectic in 1300 ℃ smelting furnace, reel off raw silk from cocoons at a high speed by the platinum bushing then, in drawing process, need once slurry, broken silk filoplume in spinning process, occurs to prevent yarn.Tens of to hundreds of of the glass fibers of taking out (the about 4-9um of filament diameter) do not wait and are around on the spinning cake, add by twisting machine after drying to be twisted into a yarn, use for weaving glass fiber cloth.
The glass fabric manufacturing technique is specially: 1. warping, earlier warp thread is arranged by some, and batch on axle by warping machines; 2. starching is carried out the secondary starching to warp thread, and because of slurry ABRASION RESISTANCE of warp thread is not enough, the purpose of this operation is mainly in order to protect warp thread high-speed friction on air-jet loom not produce brokenly the silk filoplume; 3. weave cotton cloth, behind the warp sizing, picking is weaved cotton cloth on air-jet loom, and the cloth that is woven is called embryo cloth; 4. destarch, after embryo cloth is weaved and is finished, the glass fiber yarn surface slurry and secondary slurry " are retired from political life after winning tremendous successes " in the embryo cloth, need through hot destarch burn off, hot destarch generally is divided into twice, is continuous destarch for the first time, the slurry of burn off 99%, for batch destarch, be mainly the mode of smouldering for the second time, the residual slurry rate of glass cloth is fallen back on below 0.1%; 5. handle, again glass fabric is carried out the silane surface coupling agent treatment after the destarch, obtain required electronic-grade glass finished fabric.
As the electronic-grade glass fiber cloth that the circuit board reinforcing material is used, the secondary slurry starching mainly has influence on its following several respects performance: 1. fabric appearance quality if there is a broken silk filoplume in glass fabric, finally can cause circuit board short circuit/open circuit; And electronic product develops to short and small frivolous direction at present, and live width and distance between centers of tracks are more and more littler, the glass fabric presentation quality is required just higher.2. warp width, in general, the warp size convergence is strong more, warp width is narrow more, this is unfavorable for the infiltration of glass fabric at CCL client resin, and is bad if resin soaks into, and it is unusual to produce in the glass fiber yarn bundle starved etc., make circuit board short circuit occur, and dimensional stability is relatively poor behind the narrower glass fabric pressing plate of warp width.3. desizability is because of slurry just shields in the process of weaving cotton cloth, the most at last by hot destarch burn off, so its ash content has determined the destarch condition: ash content is little, the destarch temperature is low, and the destarch time is short, the loss of glass fabric tension intensity is little, and helps saving energy and reduce the cost; Ash content is big, destarch temperature height, and the destarch time is long, and glass fabric tension intensity loss is big, and it is unusual to be prone to disconnected cloth in client, and wastes energy, and increases cost; 4. the feature of environmental protection in the starching process, all can have remaining slurry to drain, the easy more degraded of remaining slurry environmental protection more every day; In hot destarch process, whether the combustion requirements of slurry lacked generation as far as possible and or not toxic and harmful, in order to the protection environment.
Secondary slurry mainly uses PVA at present, and its shortcoming is that convergence is strong, and the glass fabric fabric appearance of being produced is fair, and warp width is narrower, and PVA difficult degradation (disabled in Europe), can produce a small amount of toxic gas after the burning.
Summary of the invention
The object of the invention is to provide a kind of new slurry, promotes the fabric appearance quality on existing secondary slurry technical foundation, and increases warp width, reaches effect in energy saving and environmental protection simultaneously.The electronic-grade glass fiber cloth that uses this formula of size to produce, have slimming, homogenising, resin wettability faster, be highly suitable for printed circuit board (pcb) insulation reinforcing material, be widely used in high-end products such as mobile phone board, notebook computer, automobile board, digital camera, digital player, navigator.
Environment-friendly and green secondary slurry of electronic-grade glass fiber cloth of the present invention is achieved through the following technical solutions, and by weight percentage, comprises following component:
Film forming agent starch 5%--10%,
Smooth agent 0.5%--1%,
Binding agent 0.5%--1%,
Surfactant 0.01%---0.05%,
Deionized water is a surplus.
Described film forming agent is mainly modified starch, and ash content is below 0.3%, and 50 ℃ of viscosity have good film forming at 8-10cp, and institute's film forming is more wear-resisting, good toughness.
Described smooth agent is mainly oil substances, and its content is 0.5%-1%; Can under the prerequisite of not destroying serous coat, effectively improve the slickness of serous coat, reduce the coefficient of friction between warp thread and the loom.
Described binding agent is mainly aqueous epoxy resins, and its consumption is 0.5-1%; The interface that slurry of effective adhesive and secondary slurry can be arranged strengthens the intensity of secondary slurry institute film forming simultaneously.
Described surfactant is mainly methoxypolyethylene glycol, and it can effectively reduce slurry surface tension force, helps slurry to yarn bundle internal penetration.
Described formula of size is finished mashing off by following mashing off step:
(1) earlier main slurry starch (starch) is taken by weighing a certain amount of size cooking pan of pouring into, add a certain amount of deionized water and stir and be warming up to 90 ℃, insulation half an hour, add deionized water then to specifying liquid level;
(2) add load weighted binding agent, smooth agent, surfactant stirs 15min;
(3) it is stand-by to treat to squeeze into slurry storing tank after slurry temperature is reduced to 60 ℃;
The sizing technique method of described environment-friendly and green secondary slurry of electronic-grade glass fiber cloth earlier at 100-120 ℃ of temperature preliminary drying, is dried under 160-180 ℃ of temperature again.
The glass fibre of formula of size of the present invention and the scope of glass fabric: formula of size provided by the invention is applicable to that filament diameter is the glass fiber yarn of 5-9um, warp thread single fiber radical is the starching of 50-400 root fiber, wherein especially to filament diameter 5um, the warp sizing of single fiber radical 50-200 root has good quality; The cloth kind is for promptly in the corresponding IPC standard: 106,1080,1067,1035 etc.Because this slurry covering property is better than permeability, mainly based on coating, infiltration is auxilliary for spun yarn, so just can play best effect.
Sizing process function to glass fiber warps describes: glass cloth is in weaving process, and heald frame drives the warp thread up-down alternative motion and constantly forms opening, and weft yarn passes from opening, beats up and warp thread is woven into the plain weave glass cloth by reed.So in the process of weaving cotton cloth, warp thread and heald frame, reed, menopause tablet and warp thread self be consistent to exist friction, this friction can cause warp thread to produce a broken silk filoplume, even broken yarn.For preventing brokenly that the silk filoplume produces, before weaving glass fiber cloth, need that glass fiber warps is carried out the secondary starching and handle, impaired with the protection warp thread because of friction.
To the explanation of the advance of the described formula of size of patent of the present invention: 1. desizability; because cast off behind the cloth; the function of slurry protection yarn has not just needed, and must remove slurry, in the Dow Chemical treatment process of back silane coupler is carried out on the glass fabric surface then and handles.Normally adopt hot destarch in the glass fabric industry, be about to slurry and burn at a certain temperature, the residual slurry rate of industry remains on below 0.1% at present.If the slurry desizability is poor, be difficult for burn off after the starching, will make residual slurry rate become big, the surface treatment of unfavorable later process; If by increasing temperature and prolonging destarch burning time, can make the loss of strength of glass fabric too many again, it is unusual to occur disconnected cloth in later process, and increases temperature and time expand can increase energy consumption, causes cost to increase and environmental pollution.Traditional slurry PVA ash content is between 0.3-0.5%, desizability belongs to medium, and the described formula of size of patent of the present invention is because main body is a starch, ash content is below 0.3%, so have good desizability, can reduce the destarch temperature and shorten the destarch time, guarantee that promptly the tension intensity of glass fabric is suffered a loss less, save the energy again.2. the feature of environmental protection, the sizing board is after finishing a kind, and the remaining slurry of need draining cleans board.These slurries of draining need can discharge after waste water treatment tank is handled.Traditional glass fibre slurry is PVA, and its degradability is poor, and the described formula of size main body of patent of the present invention is a starch based, and degradability is very good, helps protecting environment; In addition, slurry had better not produce toxic and harmful in burning destarch process, conventional P VA slurry is proved to be in Europe in the combustion process can produce benzene, how the class harmful substance, and the described formula of size main body of this patent of invention is a starch, and burning can not produce toxic and harmful.3. good fabric appearance quality, conventional P VA slurry film forming softness, but its flatness is not enough, added smooth agent in the described formula of size of patent of the present invention, make institute's film forming not only soft but also smooth, can effectively reduce friction, to reduce the generation of the broken silk of cloth cover filoplume.4. wideer warp width, this formula of size does not have PVA so strong because of convergence, so warp width is wide than the warp width of conventional P VA formula of size behind the sizing, the glass cloth of knitting has good wettability and dimensional stability.
