Abstract

The invention discloses a preparation process of a heat shield of a storage battery. The preparation process comprises the following steps: an aluminum alloy material is rolled at high temperature under high pressure to be made into an outer layer of the heat shield of the storage battery; nano titania, nanosilicon dioxide, hollow microspheres, an adhesive, polypropylene and polyurethane foam plastic are stirred and mixed under a heating condition, and a mixture is prepared; the mixture is rolled to be made into the inner layer of the heat shield; the outer layer of the heat shield and the inner layer of the heat shield are stacked orderly, then put into a heat shield die cavity for compression molding and punching and subjected to fine finishing after being cooled and shaped. Compared with a traditional heat shield of a storage battery, the heat shield has the advantages that a thermal-insulated middle layer is omitted while the thermal insulating effect is guaranteed, a thermal-insulating material is modified through an added auxiliary, the oxidation resistance and the anti-aging performance of the heat shield of the storage battery are effectively improved, the heat shield of the storage battery is light in mass, thermal-insulated and good in cold-proof effect, has a wide temperature-resisting range, adopts a simple preparation process and is worth popularization.

Description

Technical field [0001] The invention relates to the technical field of automobile spare parts, in particular to a preparation process of a battery heat shield. Background technique [0002] The battery is an indispensable part of the car. It is a device that converts chemical energy into electrical energy. It is a DC power supply. Its functions are: when the engine is started, it provides the engine with a powerful starting current (generally up to 200-600A); When the generator is overloaded, it can assist the generator to supply power to the electrical equipment; when the engine is idling, it can supply power to the electrical equipment; the battery is also a large-capacity capacitor that can protect the car's electrical appliances; when the generator terminal voltage is higher than lead When the battery's electromotive force is used, part of the electric energy is converted into chemical energy and stored, that is, it is charged. The battery is an electronic device that is sen...
