Problems solved by technology

However, the commonly used ABS resin is sensitive to engine oil, and the surface of the battery case is easily corroded after being stained with engine oil, and cracks under the action of internal stress.
In the environment where the battery is used, especially in the environment of the car, it is inevitable that it will be stained with engine oil, which will cause the battery to crack, fail, leak acid, and corrode other equipment

Abstract

The invention provides a high-strength oil-resistant storage battery case material and a preparation method thereof. The technical scheme is as follows: the preparation method comprises the following steps: uniformly mixing 83-93 parts by weight of ABS (acrylonitrile-butadiene-styrene) resin, 4-10 parts by weight of polyester material and 2-8 parts by weight of compatilizer, sending into a double screw extruder, carrying out six-region reaction molding, cooling, drying and granulating to obtain the plastic alloy. The plastic alloy maintains the advantages of high impact resistance and beautiful appearance in the ABS resin, greatly enhances the organic solvent corrosion resistance, and is very suitable for lead-acid storage battery cases in organic oil and other organic solvent environments.

Description

Technical field: [0001] The invention relates to the technical field of polymer materials, in particular to the field of lead-acid storage battery shell materials. Background technique: [0002] After more than 150 years of development, lead-acid batteries have mature technology, low cost, and excellent performance. They are widely used in many economic fields such as transportation, communication, electric power, military, navigation, and aviation, and have become an indispensable and important chemical power source. As one of the three major parts of lead-acid batteries, the battery case is used to carry all the constituent materials such as the plate, separator, electrolyte, etc., and requires good acid and alkali resistance, high strength and good processability. ABS resin is the most commonly used raw material for battery cases, which is cheap, beautiful and strong. However, the commonly used ABS resin is sensitive to engine oil substances. The surface of the battery c...
