Sodium lignosulfonate 0.1-0.4kg, silica 0.1-0.5kg, CMC aqueous solution 0.14-1kg, water 7-9kg.Technological process is plate
Grid casting, lead plaster manufacture, smear, pouring acid, solidification, chemical conversion, washing, dry, point plate, packaging.The colloid polar plate of the inventive method
Complicated component, pole plate processing technology difficulty is big.
Publication No. CN103730695A Chinese patent literature discloses a kind of preparation method of colloid battery, including will
Pole plate is put into cell negative terminal after being assembled into pole group, then injects colloidal electrolyte to cell negative terminal, then through formation charging and envelope
Dress, obtains the colloid battery, and the process that pole plate is assembled into pole group includes：(1) polylith polar plate interval is arranged；(2) to pole
Insert pecten between property each lug of identical, the bottom surface of pecten is against the top edge of pole plate；(3) welded on each lug of polarity identical
Connect bus-bar；(4) dividing plate is inserted between adjacent pole plate, obtains the pole group.
There is many weak points in the production technology of colloid battery：First, the partial electrolyte liquid extracted out after Battery formation terminates
Part colloidal solution is contained in the inside, wastes more；2nd, acid adding operative employee also needs to the colloid electrolysis behind acid adding machine before leaving offices
Liquid is extracted into inside cold sour machine, wastes energy cost；3rd, silicon dioxide colloid mother liquor, which is added in electrolyte, causes charging resistor to increase
Plus, then, battery temperature is more than 60 DEG C in charging process, and often pause cooling, ultimately results in charge cycle and prolong in charging process
It is long.
The content of the invention
In order to solve the problems of existing silicon gel electrolyte class battery, the invention provides a kind of production cost is low,
Good silicon dioxide colloid pole plate of polar board surface silica uniformity and preparation method thereof.
A kind of preparation method of silicon dioxide colloid pole plate, it is characterised in that comprise the following steps：
(1) it is coated with：By tow sides spray, the coating silica colloid aqueous solution of green plate, stand, obtain wet pole
Plate；The dioxide/silica gel bulk concentration of the described silicon dioxide colloid aqueous solution is 0.2-0.5wt%；
(2) dry：The wet pole plate obtains silicon dioxide colloid pole plate after temperature-controlled drying.
Silicon dioxide colloid is obtained in the surface coating silica colloid aqueous solution of green plate, then after solidification is dried
Pole plate, prepared silicon dioxide colloid pole plate can effectively solve battery issuable list during long-term use and only fall
Afterwards the problem of, while can also avoid the charging temperature that addition silicon dioxide colloid electrolyte is brought into battery too high, it is raw
Produce the problems such as cost is high.
It is by the inventive method that silicon dioxide colloid is coated and cured in polar board surface, improve polar board surface titanium dioxide
Colloidal silica uniformity, reduces the phenomenon of acid solution layering, and the compound efficiency of pole plate oxygen, battery fluid loss is reduced, and improves battery
Service life.Compared with the existing method that silicon dioxde solution is added into electrolyte, the dioxide/silica gel of the inventive method
Liquid solution usage amount is few, and production cost is low；The resistance ratio of electrolyte is relatively low, and internal temperature of battery will not be too high during charging, reduces
For the production interruption for cooling and causing, production efficiency is improved.
Preferably, the dioxide/silica gel bulk concentration of the silicon dioxide colloid aqueous solution is 0.3-0.4wt%.
In order to improve adhesive force of the silicon dioxide colloid on green plate, preferably, green plate is first passed through before coating
Pre-process, described pre-treatment step is：Green plate is first completely immersed in the dilute sulfuric acid aqueous solution that density is 1.06-1.09g/mL
In, positive plate soak time is 40-60min, and negative plate soak time is 20-30min, is dried again at 30-60 DEG C after immersion
1-2h, obtains acidleach pole plate, and acidleach pole plate carries out the coating process of step (1) again.
It is different that green plate is divided into the acid soak time in positive plate and negative plate, preprocessing process.Green plate is through peracid treatment
Afterwards, it is not only limited to prevent the generation of polar board surface crackle, moreover it is possible to promote colloid coating fluid with distribution, improve silicon dioxide colloid
The uniformity of polar board surface.
After the completion of green plate or the spray coating of acidleach pole plate, diameter is not dried, preferably, in step (1), applying
After the completion of cloth, then 0.5-1h is stood, obtain wet pole plate.
The process of standing can promote the silicon dioxide colloid aqueous solution fully to spread, absorb on the surface of pole plate, be conducive to carrying
The uniformity of high polar board surface silicon dioxide colloid, reduces situations such as being bonded between slight crack, pole plate.
In industrial production, coating process on glue spreader serialization carry out, pole plate is placed on glue spreader, pole plate according to
Pole plate hangers, closing vacuum cup, pole plate are drawn by vacuum cup to fall on chain, chain hook tape movable plate electrode, titanium dioxide
The colloidal silica aqueous solution sprays pole plate upper and lower surface, then stands 0.5-1h, obtains wet pole plate.
In step (2), wet pole plate is by three sections of temperature-controlled dryings, the temperature setting of three sections of temperature-controlled dryings：First paragraph 150
℃-170℃；190-210 DEG C of second segment；3rd section 160 DEG C -180 DEG C.
Preferably, the drying time of first paragraph is 0.1-0.15h；The drying time of second segment is 0.5-0.7h；3rd
The drying time of section is 1-1.5h.
The inventive method additionally provides the silicon dioxide colloid pole plate prepared by a kind of use above method.
Moisture on pole plate should try one's best less, preferably, the moisture of obtained silicon dioxide colloid pole plate is less than
0.4%.
The moisture of silicon dioxide colloid pole plate is to the storage of pole plate and using all having a very big impact, and moisture is higher than
0.4%, dried silica pole plate easily ftractures when storage, so as to influence the life-span of prepared battery.
Present invention additionally comprises application of the above-mentioned silicon dioxide colloid pole plate in lead-acid storage battery production.
Compared with existing method, the inventive method has advantages below：
