Laurate is prepared, this lead-acid accumulator plastic housing is by antioxidant and resin miscible, not due to antioxidant and resin compatible
It is good, cause antioxidant to disperse unevenness in resin, antioxidant effect is poor, lead bad with resin compatible additionally, due to antioxidant
Acid accumulator can be precipitated for a long time using rear antioxidant from lead-acid accumulator plastic housing, lead to the anti-aging of lead-acid accumulator plastic housing
Performance substantially reduces, and accelerates the aging of lead-acid accumulator.
Summary of the invention
The present invention is to lead to anti-aging property difference and anti-oxidant to overcome prior art antioxidant and resin compatible poor
Agent is easy the problem of being precipitated from resin, provides a kind of lead-acid accumulator plastic housing that antiageing effect is good and lasting.
The present invention also provides a kind of preparation methods of the anti-oxidant plastic housing of lead-acid accumulator.
To achieve the goals above, the invention adopts the following technical scheme: a kind of anti-oxidant plastic housing of lead-acid accumulator, including
Following components of weight:
