Abstract
The invention discloses a composite film for covering a storage battery, and belongs to the field of composite materials. An insulated material layer is arranged in a carbon fiber protection outer layer; a gold foil layer is arranged in the insulated material layer; a function material layer is arranged in the gold foil layer; and an acid-resistant and corrosion-resistant layer is arranged in the function material layer. The composite film has the benefits that a carbon fiber material is arranged in an outer layer of the composite film, so that the composite film is wear-resistant and prolongs the service life; and an insulated material and a corrosion-resistant material are arranged in the composite film, so that the electric leakage phenomenon does not occur while leaked packaging liquid cannot flow out.
Description
?
Technical fieldThe present invention relates to belong to field of compound material for the composite membrane that coats storage battery.
Background technologyStorage battery uses because can also charge and then continue after the discharge, receive praises from customers, electrolyte long meeting corrosion service time storage battery inwall in the storage battery, cause leaking, and the generation of this situation, the user often can't find rapidly, causes the appearance of dangerous situation, and the leakage of a large amount of electrolyte also is a kind of wasting of resources simultaneously.
Summary of the inventionIn view of the defective that prior art exists, the purpose of this invention is to provide a kind of composite membrane for coating storage battery.
For achieving the above object; the technology used in the present invention solution is: being used for coating the composite membrane of storage battery, being provided with insulation material layer in the carbon fiber protection skin, is the goldleaf layer in the insulation material layer; being the functional material layer in the goldleaf layer, is acidproof etch resistant layer in the functional material layer.
Be used for coating the composite membrane of storage battery, its beneficial effect is: this composite membrane skin is carbon fibre material, resistance to wears, and increases the service life, and inside is provided with insulating material and corrosion-resistant material, guarantees can not produce leaky when leakage can't be outflowed.
Description of drawings
Fig. 1 is the structure chart for the composite membrane that coats storage battery;
Fig. 1 Reference numeral is as follows: 1, carbon fiber protection is outer, and 2, insulation material layer, 3, the goldleaf layer, 4, the functional material layer, 5, acidproof etch resistant layer.
