Problems solved by technology

[0002] With the continuous progress of society and the continuous improvement of people's living standards, various new materials, especially plastics, are widely used as new materials on battery car charger shells, but once a fire occurs, it will cause very heavy losses. Toxic gases such as hydrogen chloride, hydrogen cyanide, hydrogen fluoride, styrene, etc. are produced, and the heat generated when the polymer material is burned is large, the temperature is high, the burning speed is fast, and it is easy to cause incomplete combustion and generate a large amount of black smoke. Escape, lifesaving and other work bring difficulties, and at the same time, the battery car charger shell has poor tear resistance, which needs to be solved urgently

Abstract

The invention discloses a flame-retardant shell material for battery car chargers. Raw materials of the flame-retardant shell material comprise, by weight, 125-130 parts of a base material, 2-10 partsof modified Sa-son seed gum, 0.3-1 part of disproportionated rosin, 1-2 parts of zinc stearate, 0.4-1 part of 2-ethylhexyl 9,10-epoxyoctadecanoate, 1.5-2.5 parts of a cross-linking agent, 20-30 partsof magnesium hydroxide, 4-12 parts of melamine formaldehyde resin, 8-12 parts of white carbon black, 10-16 parts of coal gangue, 2-8 parts of calcined kaolin, 10-16 parts of sepiolite powder and 0.1-0.6 part of a titanate coupling agent. The modified Sa-son seed gum is prepared by the following steps: stirring Sa-son seed gum, lactalbumin and water, adding the polyurethane fibers and glycerol triglycidyl ether, performing stirring, introducing nitrogen until saturation, adding potassium persulfate, heating and stirring the obtained mixture, filtering the mixture to obtain a precipitate, washing the precipitate, and drying the washed precipitate to obtain the modified Sa-son seed gum.

Description

Technical field [0001] The invention relates to the technical field of chargers, in particular to a flame-retardant shell material for battery car chargers. Background technique [0002] With the continuous progress of society and the continuous improvement of people’s living standards, various new materials, especially plastics, are widely used as new materials in battery car charger shells. However, once a fire occurs, it will cause very heavy losses. Plastics will catch fire. It produces toxic gases such as hydrogen chloride, hydrogen cyanide, hydrogen fluoride, styrene, etc., and the high heat, high temperature, and fast burning speed generated when polymer materials are burned are easy to cause incomplete combustion and produce a lot of black smoke. Escape, life-saving and other tasks have brought difficulties, and the battery charger shell has poor tear resistance, which needs to be solved urgently. Summary of the invention [0003] Based on the technical problems existing ...
