Abstract
The invention discloses a coating agent for casting a lead acid battery slab lattices, which mainly comprises the following components in part by weight: 1,000+/-20 milliliters of water, 65+/-5 milliliters of sodium silicate, 60+/-5 grams of cork powder, 5+/-2 grams of kaolin and 5+/-2 grams of aerosol. By adopting the scheme, in the coating agent, the sodium silicate is a type of glue, the cork powder is a type of heat insulating material, the added kaolin has a function of increasing the caking property and has an efficiency of enhancing heat insulation; and the aerosol can form a hydrosol after being added into aqueous solution, and the hydrosol can increase pore spaces of an adhesive layer after being sprayed on a die. Compared with the prior art, by using the coating agent to perform production, the number of the slab lattices produced by spraying the coating agent once by the die can be 1,500 to 4,500 chunks, and the service time of the coating agent is long, so the production efficiency of the slab lattices is improved. Besides, environment pollution caused by die brushing and influences on the health of works are reduced.
Description
Technical field
The present invention relates to lead-acid accumulator and make the field, the coat that uses when specifically being lead-acid accumulator casting grid.
Background technology
Grid is the important component part of lead-acid accumulator.Grid plays conduction and supports active material in lead-acid accumulator.The structure of grid generally is made up of frame, horizontal bar, perpendicular muscle and lug, as mesh screen, and the about 1.2mm of rib cross-sectional maximum dimension.
The casting of 80% grid is come out in the lead-acid accumulator production at present, is called the casting type grid.
The grid casting needs casting plate machine and mould, designs grid according to the requirement of battery, goes out required mould according to the grid structural design again.The position of the general requirement consideration of grid design length, lug, the structure of rib and cast molding property etc.Mould is made split cavity, after the cast molding, and moulds open, grid just falls, and processes again.The grid mould is installed on the casting plate machine, when mold heated to the temperature that requires, die surface is cleaned down with wire brush, spray coat on the surface with spray gun then, after the spraying of two-sided multipass, matched moulds makes the grid of can casting.
Existing coat mainly is made up of cork powder, water and bubble flower alkali, and the effect of coat mainly is:
1. insulation effect.Main component in the coat is a cork powder, plays insulation effect, makes plumbous liquid in flow process, keep more stable temperature, avoids plumbous liquid temp fluctuated, and grid can not be shaped.The hot system of grid mould is a more complicated, and the mould inside heating system of having packed into can be heated when temperature is low, stops when temperature is high heating.Mould also has the radiating and cooling device, and generally with the water channel cooling, these all are to guarantee that mould has suitable relatively temperature.During the grid casting, plumbous liquid temp is higher, flows in the die cavity, wait the plumbous liquid full die cavity of stream rapidly, could coagulation forming.If solidify in advance, grid will partly be cast discontented, promptly can not moulding; If behind the full die cavity of plumbous flow, temperature is higher, can't solidify, after the moulds open, grid will become disintegrating slag, can not cast grid.Therefore, the suitable heat-insulating property of coat is the prerequisite of casting grid.
2. die surface is a smoother, spray coat after, die surface forms a coarse surface, the air flue that air is discharged in the die cavity when having formed plumbous liquid casting.If die venting is not smooth, can cause grid can not moulding, problems such as pore appear in grid inside.
3. the easy demoulding of the grid of casting.General not only can cast out qualified grid after hoping to spray coat, and hope that time that coat uses, the longer the better, but in fact; Existing coat sprays mould and generally can only produce the large stretch of grid of 1000-3000, crossed this amount after; Grid must be brushed mould once more with regard to the bad demoulding, the spray coat; Production efficiency receives very big influence, and labour intensity increases.And brush is during mould, and dust from flying has bad influence to workman healthy.
Summary of the invention
The purpose of this invention is to provide a kind of coating agent for casting lead acid battery slab lattices, its service time is longer, can improve the production efficiency of grid.
Technical scheme of the present invention is such: a kind of coating agent for casting lead acid battery slab lattices, mainly form by following weight portion component:
Water 1000 ± 20
Bubble flower alkali 54.2 ± 4.2
Cork powder 60 ± 5
Kaolin 5 ± 2
Aerosil 5 ± 2.
After adopting such scheme, coat of the present invention, bubble flower alkali is a kind of glue, and cork powder is a kind of insulation material, and the kaolin of interpolation has the close-burning function of increasing, and the usefulness of promoting insulation is arranged again; Aerosil joins in the aqueous solution, can form the hydrosol, is sprayed onto the hole that can increase adhesion layer on the mould.Compared with prior art, use coat of the present invention to produce, producible grid quantity of coat of mould spraying can reach the 1500-4500 sheet, and the service time of coat is longer, thereby has improved the production efficiency of grid.And, reduced the brush environmental pollution that mould brought, and the influence healthy to the workman.
The specific embodiment
A kind of coating agent for casting lead acid battery slab lattices of the present invention, mainly form by following weight portion component:
Water 1000 ± 20
Bubble flower alkali 54.2 ± 4.2
Cork powder 60 ± 5
Kaolin 5 ± 2
Aerosil 5 ± 2.
As a preferred embodiment, the desirable 1000g of the consumption of water, the desirable 54.2g of consumption of bubble flower alkali, the desirable 65g of the consumption of cork powder, the desirable 5g of kaolinic consumption, the desirable 5g of the consumption of aerosil.
After adopting such scheme, coat of the present invention, bubble flower alkali is a kind of glue, and cork powder is a kind of insulation material, and the kaolin of interpolation has the close-burning function of increasing, and the usefulness of promoting insulation is arranged again; Aerosil joins in the aqueous solution, can form the hydrosol, is sprayed onto the hole that can increase adhesion layer on the mould.Compared with prior art, use coat of the present invention to produce, producible grid quantity of coat of mould spraying can reach the 1500-4500 sheet, and the service time of coat is longer, thereby has improved the production efficiency of grid.And, reduced the brush environmental pollution that mould brought, and the influence healthy to the workman.
