Problems solved by technology

[0002] At present, both international and domestic lead-acid battery tanks are mostly made of plastics such as PVC, ABS, and PP. The performance of the battery can be well exerted at room temperature, but the performance of the battery will decline rapidly when used at high temperature. The main reason is that Due to the relatively low elastic modulus and strength of the above materials, the battery tank has a large deformation and bulges outward under high temperature environment and high internal pressure.

After testing, the bending strength of the molding material is 150MPa, the tensile strength is 98MPa, the compressive strength is 138MPa, the thermal deformation temperature is 135℃, and the curing shrinkage rate is 4.5%.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a vinyl resin for large-scale lead-acid battery tanks and a preparation method thereof. Background technique [0002] At present, both international and domestic lead-acid battery tanks are mostly made of plastics such as PVC, ABS, and PP. The performance of the battery can be well exerted at room temperature, but the performance of the battery will decline rapidly when used at high temperature. The main reason is that Due to the relatively low elastic modulus and strength of the above materials, the battery tank has a large deformation and bulges outward under high temperature environment and high internal pressure. [0003] As an internationally recognized highly corrosion-resistant resin, vinyl resin not only retains the basic chain segment of epoxy resin in the molecule, but also has unsaturated double bonds at both ends. With its excellent corrosion res...
