Abstract

The invention discloses fluorinated plastic and a preparation method thereof, belonging to the technical field of plastic preparation. The fluorinated plastic comprises the following raw materials: phenolic resin, talcum powder, sodium alkyl benzene sulfonate, titanium tetrachloride, iron chloride, methyl methacrylate, azobisisobutyronitrile, polyvinyl chloride, a silane coupling agent, trimethylolpropane, ammonium aluminum sulfate, potassium perfluorobutyl sulfonate, calcium fluoride, a nitrogen derivative of perfluoropolyoxyalkyl carbonate, fluorinated graphene, acrylic resin, an antioxidantand a surfactant. The fluorinated plastic is prepared through the steps of mixing, stirring, ultrasonic treatment, drying, injection molding, etc. According to the invention, by adoption of the nitrogen derivative of the perfluoropolyoxyalkyl carbonate, the fluorinated graphene and the acrylic resin as reinforcing systems, barrier properties and cohesiveness of the fluorinated plastic are improved.

Description

technical field [0001] The invention belongs to the technical field of plastic preparation, and in particular relates to a fluorinated plastic and a preparation method thereof. Background technique [0002] So far, polytetrafluoroethylene still ranks first among plastics with its excellent performance, but polytetrafluoroethylene is difficult to process and expensive, thus limiting its application range. In practical applications, it is often only required that the plastic surface layer has the properties of polytetrafluoroethylene. Therefore, if the surface layer of the molded polyethylene sheet, pipe and film can be fluorinated, their performance can be greatly improved, and the cost can be greatly reduced. Fluoropolymers have been widely used and developed in many fields due to their excellent properties such as high thermal stability and chemical stability. At present, the fluorinated polymer materials used are mainly prepared by the following methods: one is to prepar...
