Problems solved by technology

During the charging process of the battery, it is very easy to explode when encountering an open flame. In order to improve the safety performance of the battery, the battery tank and battery cover of the battery need to have certain flame retardant properties, so a flame retardant will be added to the battery tank. Common flame retardants on the market have poor acid corrosion resistance. The battery tank added with flame retardant is easily corroded by sulfuric acid in the battery tank during use, and grooves and bumps often appear on the surface of the battery tank. Phenomenon, which seriously affects the performance of the battery slot

Abstract

The invention discloses a method for preparing an acid corrosion resistant battery jar. The method comprises the following operating steps: (1) uniformly mixing melamine and a formaldehyde solution, adding ammonium hydroxide into the mixture, and maintaining the temperature; (2) adding melamine pyrophosphate into the mixed solution obtained in the step (1), regulating the pH value of the mixture to be 3.5-4 by adopting a phosphoric acid solution, maintaining the temperature and reacting, centrifuging to obtain a precipitate, washing and drying the precipitate to prepare an acid corrosion resistant flame retardant; and (3) adding an ABS (Acrylonitrile Butadiene Styrene) resin, talcum powder, an antioxidant, the acid corrosion resistant flame retardant, hexadecyl trimethyl ammonium chlorideand dioctyl sebacate into a high-speed mixer, extruding, granulating, and performing injection molding, thereby obtaining the acid corrosion resistant battery jar. According to the method for preparing the acid corrosion resistant battery jar provided by the invention, the prepared battery jar is high in impact resistance, high in hardness, high in electrical resistivity, high in breakdown voltagestrength and excellent in flame-retardant property, and particularly after the flame retardant is added, the problem that the acid resistance is decreased is solved.

Description

technical field [0001] The invention belongs to the technical field of battery tank preparation, and in particular relates to a method for preparing an acid corrosion-resistant battery tank. Background technique [0002] The battery tank is the container for the lead-acid battery. In the past, the mobile batteries were mostly hard rubber tanks. The small-capacity fixed batteries used glass tanks, and the large-capacity ones used lead-lined wooden tanks. After the 1960s, the plastics industry developed rapidly, and plastic tanks began to replace hard rubber tanks and glass tanks. The plastic tank is manufactured by an injection molding machine with simple process, low cost and abundant raw materials. ABS resin is widely used in the preparation of battery tanks because of its excellent performance. During the charging process of the battery, it is very easy to explode when encountering an open flame. In order to improve the safety performance of the battery, the battery tank...
