Description
Technical field
The present invention relates to lead-acid accumulator manufacturing technology field, especially relate to a kind of lead-acid accumulator aging resistance and mould shell system
Preparation Method.
Background technology
Lead-acid accumulator through the development in more than 150 years, technology maturation, with low cost, excellent performance, be widely used in handing over
Numerous economic fields such as logical, communication, electric power, military affairs, navigation, aviation, become the indispensable important electrochmical power source of one.Electricity
Pond shell is as one of lead-acid accumulator three-major-items, and it is used for carrying all of components such as pole plate, dividing plate, electrolyte, it is desirable to
There is preferable resistance to acids and bases, high intensity and good processability.
Current lead-acid accumulator housing generally obtains through injection mo(u)lding with ABS resin for primary raw material, but conventional ABS
, there is certain potential safety hazard, and weather resistance be poor with mechanical performance in resins fire retardant poor-performing, in storage, machine-shaping
, there are the problems such as mechanical property deterioration, the hardening embrittlement of material in journey and recurring structure change in time during using, while by
Hygroscopicity in ABS resin and the sensitivity to moisture are relatively big, are difficult to the driest to it, the most easily cause product surface to go out
Existing spray filamentary silver stricture of vagina phenomenon, and at present for ensureing that ABS resin can be the driest, generally use improve baking temperature or dry time
Between mode, so or cause energy consumption high, or cause production efficiency to be substantially reduced.
Summary of the invention
The present invention is to solve the problems referred to above existing for the lead-acid accumulator of prior art, it is provided that a kind of technique step
Rapid simple, workable, energy consumption is low, and production efficiency is high, and the lead-acid accumulator aging resistance of applicable industrialized production is moulded shell and prepared
Method, prepared girdle of moulding protects, and production cost is low, fire-retardant and mechanical performance is excellent with weatherability.
To achieve these goals, the present invention is by the following technical solutions:
A kind of lead-acid accumulator aging resistance of the present invention moulds shell preparation method, comprises the following steps:
(1) prepare surface modification bamboo fibre: added by bamboo fibre in chlorosulfonic acid, be heated to 80 ~ 100 DEG C of swelling 1 ~ 3h, cooling, mistake
Filter, filtrate is washed with water to pH be neutrality, vacuum drying, add and wetting agent carried out soak after 30 ~ 60min in 95 ~ 105
Dry at DEG C, obtain surface modification bamboo fibre, stand-by.Chlorosulfonic acid can make bamboo fibre boundling the most swelling so that it is dispersion, is conducive to
Improve its dispersibility, it is simple to wetting agent is abundant, homogeneous immersion；Wetting agent can make the bamboo fibre surface after drying can form one layer
Protecting film, it is to avoid material damages when injection mo(u)lding, ensures the reservation length of bamboo fibre as far as possible, it addition, the bamboo of soaking mistake is fine
Dimension table surface roughness also becomes big, and forms more chemical bond between resin, increases the coefficient of friction between resin, so that
Interface shear strength increases, and improves toughness.
(2) modified aluminium hydroxide is prepared: be first dispersed in water by aluminium hydroxide and be configured to dividing of mass percentage concentration 5 ~ 10%
Dissipate liquid, after being heated with stirring to 70 ~ 80 DEG C, add dispersion liquid adds by the tripolycyanamide for aluminium hydroxide quality 10 ~ 15% and mix all
Even, obtain reactant liquor；Press the tripolycyanamide amount with formaldehyde material again than 1:2 ~ 3, formalin is dropped to constant temperature in reactant liquor anti-
Answer 4 ~ 8h, reactant is filtered, washing, dried, obtain modified aluminium hydroxide, stand-by.Can by tripolycyanamide and formaldehyde crosslinking
Form thin film in surface of aluminum hydroxide, the heat stability of aluminium hydroxide can be improved, more can make aluminium hydroxide and resin base

Reason 30 ~ 60min, at 70 ~ 80 DEG C, drying modified zeolite powder, stand-by.
(4) injection mo(u)lding: by 40 ~ 50 parts of ABS resin, 20 ~ 30 parts of polyvinyl chloride resins, 5 ~ 10 parts of surface modification bamboo fibres, 5 ~ 10
Part modified aluminium hydroxide, 5 ~ 10 parts of chlorinated polyethylenees, 1 ~ 3 part of lubricant, 3 ~ 5 parts of modified zeolite powders, 0.5 ~ 1 part of antioxidant AT-
After the weight of 1078,0.5 ~ 1 part of dibutyltin dilaurate of 10,0.1 ~ 0.5 part of antioxidant weighs each component, will
ABS resin and polyvinyl chloride resin are placed in dehydrated alcohol and soak and stir 5 ~ 10min, dry, and will add note after each component mix homogeneously
Molding machine injection mo(u)lding, after through checking the qualified lead-acid accumulator aging resistance that i.e. obtains to mould shell.The formula moulding shell material is entered by the present invention
Row Optimal improvements, adds quantitative polyvinyl chloride resin in ABS resin, by both material synergism, and be aided with antioxidant AT-10,
Antioxidant 1078 and the resistance to thermal oxidation stability system of dibutyltin dilaurate composition so that the weatherability moulding shell obtains significantly
Improve, the problem efficiently solving the jaundice that becomes fragile poor, the most aging of housing weather resistance, and the mechanicalness of material can be improved simultaneously
Can, dibutyltin dilaurate is except as optothermal stabilizer, making material have excellent light stability and the work of the transparency
With outward, its another effect is the melt viscosity that can improve whole material system, i.e. improves processing fluidity, solves because adding surface
Cause integral material processing fluidity to reduce after modified bamboo fiber, aluminium hydroxide and modified zeolite powder to be unfavorable for moulding asking of casing forming
Topic；Aluminium hydroxide is a kind of cheap fire retardant, extensively applies in fire proofing, but it needs bigger addition (logical
Often need more than 20%) just there is fire retardation, itself and ABS resin, polyvinyl chloride resin poor compatibility simultaneously, and dispersibility in the material
Difference, the present invention uses modified aluminium hydroxide as fire retardant, excellent fireproof performance, good thermal stability, and good dispersion, with
