Description
Technical field
The present invention relates to a kind of high-performance and be coated with paperboard and preparation method thereof, can be applicable to the preparation of lead-acid accumulator.
Background technology
As one of important electrochmical power source, in various Application Areas development rapidly, but also there is the phenomenon of serious environment pollution in process of production in lead-acid accumulator.The grid manufacturing technique such as expanded type (drawing in the net), punching, continuous casting and rolling, for current domestic general " gravity grid casting " manufacturing technique, are " chloride plate clearer production technologies ".The flow process of this new technology is: first by ". g., lead tape continuous casting and rolling " technology, lead pig is made into continuous print. g., lead tape, grid is manufactured again by " continuous punching net (punching) technology " or " draw in the net technology ", then through dual-side coating machine coating lead plaster, lead accumulator grid is finally made.This technology is mainly cold working (except molten lead), plumbous liquid accurately controls in the temperature range (327-340 DEG C) close to fusing point, then through the metal structure of cooling acquisition crystallization refinement fast, follow-up continuous pressure rolling and draw in the net, the process such as punching is all carry out at normal temperatures, the enforcement of this technique avoids and adopts high temperature and the stirring to plumbous liquid, lead fume and lead skim can not be produced, therefore blocked issuable lead fume discharge completely, greatly reduced energy consumption and lead loss simultaneously.
Draw in the net, range of application that continuous casting connects the grid production technology continuously such as pressure, continuously punching is increasing, these modes account for dominant position in automobile batteries is produced.In the continuous coated plate process of these grids, general needs adopts painting paperboard, is attached to pole plate two sides, prevents lead plaster from coming off and lead plaster adhesion on equipment, and mutually adhere to each other when preventing pole plate stacking when the Main Function of paper is coated plate.Have the protection of paper, in pole plate transport, Assembling Production process, greatly reduce lead dust, be conducive to environmental protection, in Battery formation and use procedure, paper dissolves in the electrolytic solution.
The material of existing painting paperboard is the common paper of string, there is following shortcoming: heat resistance is poor, easily occurs pole plate adhesion phenomenon in drying course; Moisture is high, general >=6.4%, reduces pole plate drying efficiency; Impurity ion content is high, especially Fe, Cl ion concentration >=100ppm, accelerates the self discharge of battery later stage, causes battery capacity to decay; It is weak that string inhales sour ability, is unfavorable for the absorption to acid in pole plate formation process, increases the internal resistance of battery; Later stage vitriolization speed is different, and paper is also partly present in polar board surface after changing into, and increases internal resistance, causes the difference of battery capacity and cryogenic property.
Summary of the invention
The object of this invention is to provide a kind of high-performance and be coated with paperboard and preparation method thereof.
For solving the problems of the technologies described above, technical scheme of the present invention is:
A kind of high-performance is coated with paperboard, and be prepared from by oxytalan, described oxytalan is the mixture of one or more any proportionings in medium-alkali glass fibre, high alkali glass fibre, ceramic fibre or PTFE fiber.
Above-mentioned painting paperboard to efficiently solve in prior art lead-acid battery be coated with poor, the easy bonding pole plate of paperboard temperature tolerance, moisture greatly, Fe, Cl ion concentration is high, inhale that sour ability is weak, vitriolization speed not parity problem; The present invention is coated with paperboard to be had and comparatively strong inhales sour liquid-keeping property, is conducive to the changing into of battery, effectively reduces the internal resistance of cell, acid-resistant and anti-high-temperature, sticky pole plate, Fe, Cl ion concentration≤30ppm, and the lead-acid battery utilizing it to produce has the superior function of, battery capacity little without later stage self discharge, internal resistance and cryogenic property indifference.
Above-mentioned dictyosome can be polyester webs, also can be stainless steel cloth.
Described oxytalan is the mixture of medium-alkali glass fibre and high alkali glass fibre, and the filament diameter of medium-alkali glass fibre and high alkali glass fibre is 1 ~ 16 μm, and length is 1 ~ 30mm.
The mixture of described oxytalan to be PTFE fiber and high alkali glass fibre mass ratio be (100:0) ~ (30:70), the filament diameter of PTFE fiber and high alkali glass fibre is 1 ~ 16 μm, and length is 1 ~ 30mm.
Above-mentionedly select medium-alkali glass fibre (total content of alkali metal oxide Na2O and K2O is 11.9 ~ 12.4%), the thin staple fibre of high alkali glass fibre (the total content > 12.4% of alkali metal oxide Na2O and K2O), adopt proportioning, dispersion, making beating, become net, dehydration, solidification, the wet method copy paper explained hereafter glass fibre batched is coated with paperboard, by controlling solid content and the starching flow of slurry and rushing slurry flow, oblique net (forming web, fourdrinier wire, its effect is that load glass fibre advances, be convenient to vacuum draw moisture) linear velocity (speed of a motor vehicle, be similar to oven dry, rolling speed) etc. control the density of paper and thickness.
Applicant finds after deliberation, medium-alkali glass fibre and high alkali glass fibre is used in combination not only can mutually make up respective deficiency, and create unexpected cooperative effect, gained is coated with paperboard and has that intensity is high, water-tolerant, heat resistance are good, inhale acid can strong, there is the not characteristic such as viscosity.
The filament diameter of medium-alkali glass fibre and high alkali glass fibre is all preferably 0.5 ~ 13 μm, is more preferably 1 ~ 12 μm, and length is all preferably 2 ~ 25mm, is more preferably 3 ~ 20mm.The intensity being coated with paperboard can be ensured so further, promote the cooperative effect between medium-alkali glass fibre and high alkali glass fibre.
It is 0.1 ~ 0.6mm that high-performance is coated with the thick of paperboard, be preferably 0.15 ~ 0.5mm, be more preferably 0.2 ~ 0.4mm, the mass ratio of medium-alkali glass fibre and high alkali glass fibre is (1:0.1) ~ (1:10), be preferably (1:0.5) ~ (1:9), be more preferably (1:1) ~ (1:8).Further can improve the performance that gained is coated with paperboard like this.
Above-mentioned high-performance is coated with the preparation method of paperboard, comprises the following steps that order connects:
A, to be added to the water by oxytalan, making beating homogenizing, obtain slurry, wherein, the quality of oxytalan and the mass ratio of water are 1:50 ~ 1:200;
B, steps A gained slurry is become net, dries, sloughs dictyosome, rolling on dictyosome, to obtain final product, wherein, Cheng Wangshi, starching flow is 20 ~ 160L/min, and punching slurry flow is 100 ~ 900L/min.
Without there being bonding agent in painting paperboard prepared by said method, forms enough mechanical strengths by the sealed mechanism that links between fiber, resistance to elevated temperatures is good, can not bonding pole plate; Painting paperboard of the present invention has higher porosity so the acid energy of suction is good; The lead-acid battery that the painting paperboard of manufacture of the present invention is produced has battery capacity and cryogenic property indifference, without later stage self discharge, superior function that internal resistance is little.
In above-mentioned steps B, bake out temperature is 80 ~ 270 DEG C, and the time is 1 ~ 8 minute; Rolling speed is 6 ~ 50 ms/min.The performance being coated with paperboard can be ensured so further.
