Background
Lead-acid storage batteries for low-speed electric vehicles have been widely used, and the storage battery groove of the lead-acid storage battery is formed by modifying ABS materials and performing extrusion molding and injection molding. ABS is a terpolymer of acrylonitrile, butadiene and styrene, A represents acrylonitrile, B represents butadiene and S represents styrene. The plastic ABS is not influenced by water, inorganic salt, alkali and various acids, has better liquid resistance, such as lubricant, gasoline, engine oil, acid, alkali, organic solvent, brake oil and the like, and has excellent performance due to three compositions; acrylonitrile endows ABS resin with chemical stability, oil resistance, certain rigidity and hardness; the toughness, impact resistance and cold resistance of the butadiene are improved; styrene gives it good dielectric properties and good processability. In addition, the thermal deformation temperature of the ABS plastic is 93-118 ℃, and the temperature of the product can be increased by about 10 ℃ after annealing treatment. ABS still can show certain toughness at-40 ℃ and can be used within the temperature range of-40-100 ℃. Therefore, the lead-acid storage battery can is widely applied to raw materials of lead-acid storage battery cells for electric road vehicles. The cracking phenomenon of the storage battery groove in the use process troubles customers and storage battery manufacturers, and the method for detecting the cracking of the storage battery groove is very important in order to find out the reason of the cracking of the storage battery groove and avoid the occurrence of the same faults.

In the production process, the assembly pressure of the battery is 10-20kpa, so that in the test, the pressure of the monomer tank of the battery tank is adjusted to 15kpa, rosin water, brake oil, engine oil, gasoline, lubricating oil and the like are respectively coated on the end face of the storage battery, and the storage battery tank does not crack after standing for 12 hours.
Because the lead-acid battery has sulfuric acid in the production process, the method for detecting the cracking of the storage battery tank comprises the following steps of 1, smearing the sulfuric acid with the density of 1.35g/cm3 on the end face of the first battery tank, and smearing rosin water after the sulfuric acid liquid is dried; step 2, standing the battery jar for 12 hours under the pressure of 15 kpa; and 3, judging that the tank body coated with the rosin water cracks.
And (3) replacing the rosin water in the step (1) with brake oil, repeating the steps, and cracking.
And (3) replacing the rosin water in the step (1) with engine oil, and repeating the steps without cracking.
And (3) replacing the rosin water in the step (1) with gasoline, and repeating the steps without cracking.
And (3) replacing the rosin water in the step (1) with lubricating oil, and repeating the steps without cracking.
And (3) replacing the rosin water in the step (1) with the rosin water and the brake oil, repeating the steps, and cracking.
And (3) replacing the rosin water in the step (1) with the rosin water and the engine oil, repeating the steps, and cracking.
And (3) changing the rosin water in the step (1) into the rosin water and the gasoline, repeating the steps, and cracking. And (3) replacing the rosin water in the step (1) with the rosin water and the lubricating oil, repeating the steps, and cracking.
The first material of the invention can be one or any combination of materials contacted in the production process of the storage battery or materials contacted in the use process.
