Description
Technical field
The present invention relates to Lead-acid Battery Technology field, more particularly, to a kind of shock resistance lead-acid accumulator plastic housing producer
Method.
Background technology
Current international energy competition, world energy sources general layout accelerate adjustment, are utilized in traditional energy clean and effective
On the basis of, develop the clean energy resource based on the renewable sources of energy and bioenergy, promote economic green to increase, turn into only way
And common choice.Chinese Government has also successively put into effect a series of green energy resources and new energy while rapid economic development is kept
Source reasonable development, utilization, the policy of protection, regulation.And battery is as a kind of new green power, because itself safety can
Lean on, it is cost-effective, the advantages that strong environmental adaptability, it is widely used in all trades and professions.
For battery, as being then important composition portion for holding the lead accumulator shell of electrolyte and pole group's carrier
Point.The especially quality of the performance such as the impact resistance of lead accumulator housing, heat resistance, oxidative resistance and electrical resistance, is directly affected
To the height of battery cost performance.Therefore, how to improve the overall performance of lead accumulator groove turns into industry focus of attention.In recent years
Come, it is mostly more universal as lead accumulator housing raw material using ABS resin material with developing rapidly for engineering plastics,
But ABS material shock resistance is poor, easily ruptured when colliding, so as to influence service life.
For example, Authorization Notice No. CN101235184B, authorized announcement date 2010.08.18 Chinese patent discloses one kind
Special-purpose anti-flaming ABS material for lead-acid storage battery outer case.In addition to ABS, surplus is mainly composed of the following components for it：Fire retardant, synergist,
Flame retardant, toughener, compatilizer composition.The anti-flaming ABS material mainly improves the fire resistance of lead-acid storage battery outer case, but
Still unresolved ABS material shock resistance is poor, the problem of easily rupture when colliding；In addition, the preparation method of the material
