Novel switch base wiring cassette material and preparation method thereof

Abstract

The invention discloses a novel switch base wiring cassette material and relates to the field of wiring cassettes. The material comprises the following ingredients (by weight): 30-35% of PBT resin, 30-35% of PA66 resin, 10-15% of glass fiber, 2-5% of a flexibilizer, 10-15% of a fire retardant TR-02-B, 0.2-0.5% of an antioxidant 626, 0.2-0.5% of a coupling agent, and 0.2-1.5% of a dispersant. A preparation method of the novel switch base wiring cassette material comprises the following steps: drying the PBT resin in an air dry oven for a certain period of time, and drying the PA66 resin in an air dry oven for a certain period of time; premixing the dried PBT resin and PA66 resin with the flexibilizer, the fire retardant, the antioxidant, the coupling agent and the dispersant to obtain a premix; feeding the premix into a double screw extruder and extruding and granulating, and finally processing to obtain a wiring cassette upper body and a wiring cassette lower body. The prepared wiringcassette material has low cost and good environment-friendly flame retardant property, and is convenient for market promotion and application.

Description

Technical field [0001] The invention relates to the field of junction cassettes, in particular to a novel switch base junction cassette material and a preparation method thereof. Background technique [0002] In recent years, real estate at home and abroad has developed rapidly, and there is a strong demand for building-related circuits and circuit control systems. At present, the original plastic materials on the market cannot fully utilize the advantages of the new junction cassette, which mainly affects the performance and life of the cassette. If the above materials are to achieve environmentally friendly flame retardant effects, the material's tensile strength, flexural modulus, material flexibility, flame retardancy, moisture absorption stability, and cost are difficult to achieve the best balance. [0003] In order to meet the requirements of the new structure, the present invention cooperates with the invention to develop a new type of formula plastic, so that the quality p...
