Abstract

The invention discloses a preparation process of an SMC (Sheet Molding Compound) material for communication. The SMC material is prepared from the following raw materials in parts by weight: 150 parts of epoxy resin, 60 parts of vinyl acetate resin, 100 parts of reinforced fibers, 70 parts of inorganic filler, 50 parts of a mineral filler flame retardant, 20 parts of an anti-interference agent, 10 parts of an antioxidant, 15 parts of a release agent, 20 parts of a flame retardant and 0.1 part of a silane coupling agent. The epoxy resin, the vinyl acetate resin, the inorganic filler, the mineral filler flame retardant, the antioxidant, the release agent, the flame retardant and the silane coupling agent are uniformly mixed, and then two nylon films are extruded, so that reinforced fibers and resin paste are fully soaked and mixed into a whole to obtain the SMC material. The SMC material has a good anti-interference function in the use process of a communication circuit, and normal use of communication is guaranteed.

Description

technical field [0001] The invention relates to the field of SMC material preparation, in particular to a preparation process of an SMC material for communication. Background technique [0002] SMC material is sheet molding compound. SMC material is widely used in electrical, communication, transportation and other fields because of its good electrical insulation, mechanical properties, thermal stability and chemical resistance. [0003] The prior art has the following deficiencies: when the existing SMC material is used in the field of communication, due to the poor shielding property of the SMC material itself, during the communication process, the circuit is easily disturbed, which affects the communication efficiency. SUMMARY OF THE INVENTION [0004] The purpose of the present invention is to provide a preparation process of SMC material for communication, so as to solve the deficiencies in the background technology. [0005] In order to achieve the above purpose, th...
