Abstract

The invention discloses a flame-retardant ABS resin-based barrier explosion-proof material suitable for metal plating and belongs to the technical field of barrier explosion prevention. The flame-retardant ABS resin comprises 100 parts by weight of ABS resin, 25 to 45 parts by weight of a flame retardant system, 0 to 5.0 parts by weight of a lubricating agent and 0.2 to 0.6 part by weight of an antioxidant. The preparation method comprises the following steps: mixing the ABS resin, the flame retardant, the lubricating agent and the antioxidant uniformly, melting, blending and granulating the mixture by a double-screw extruding machine, performing injection molding on the flame-retardant ABS resin granules to prepare the barrier explosion-proof material with a specific structure, and coating the surface of the barrier explosion-proof material prepared by a plastic electroplating or chemical plating process with one layer of meta such as nickel and chromium to obtain flame-retardant ABSresin-based barrier explosion-proof material with the metal plating on the surface. The surface of the existing injection molded barrier explosion-proof material is coated with one metal layer with high corrosion resistance, so the flame-retardant ABS resin-based barrier explosion-proof material has excellent explosion-proof property and is more suitable for a fuel system containing strongly polarliquid.

Description

technical field [0001] The invention relates to a flame-retardant ABS resin-based barrier explosion-proof material suitable for metal coating and a preparation method thereof, which can be applied to the explosion-proof field of various alcohols and alcohol fuels, petrochemical products, natural gas, and other liquid and gaseous dangerous chemicals . Background technique [0002] Fuel is one of the essential sources of energy in modern society, and its safety during storage, transportation, and use has always been the focus of attention. Fossil fuels will remain an important source of energy for a long time to come. Gasoline, diesel, liquefied petroleum gas, natural gas and other liquid and gaseous fuels, as well as other liquid and gaseous hazardous chemicals (such as methane, benzene and other chemical raw materials) are very vulnerable to static electricity, gunshots, collisions and other external energy during storage, transportation and use. The explosion caused a lar...
