Abstract

The invention relates to a special color master batch for a black storage battery plastic slot and a manufacturing method of the special color master batch. The special color master batch is prepared from the following substances in parts by mass: 70-95 parts of carrier resin, 5-15 parts of a high-concentration black master batch, 0.5-2.5 parts of a dispersing agent, 0.5-2.5 parts of a compatilizer, 0.1-1 part of an antioxidant and 0.1-1 part of a laser marking agent, wherein the high-concentration black master batch contains the following components in parts by mass: 30-60 parts of carrier resin, 40-60 parts of carbon black, 0.8-2.8 parts of a dispersing agent, 0.8-2.8 parts of a compatilizer and 0.5-1 part of an antioxidant. The special color master batch is prepared by the steps of sampling, and carrying out secondary granulation. The special color master batch can be uniformly dispersed in a plastic matrix, so that the phenomenon of agglomeration of materials such as carbon black in the plastic matrix is avoided, and the injection-molded storage battery plastic slot can meet the requirement of high voltage breakdown resistance. Furthermore, by adding the laser marking agent into the color master batch, the marking effect of a storage battery plastic shell can be effectively improved.

Description

technical field [0001] The invention relates to a color masterbatch and a manufacturing method, in particular to a special color masterbatch and a manufacturing method for plastic tanks of black storage batteries. Background technique [0002] Plastic tanks for lead-acid batteries are usually produced by injection molding. According to the requirements of relevant technical standards, plastic tanks for batteries should meet the requirements of bearing a certain level of additional voltage within a specified time. The process of making battery plastic tanks requires a raw material blending process, which requires adding a certain proportion of black masterbatch to the raw materials. At present, the black masterbatches used in the production of battery plastic tanks are all commercially available products. The problem is that the production process of this common black masterbatch is simple. When the carbon black content in the masterbatch reaches more than 20%, when blending ...
