Abstract

The invention discloses a thermosetting plastic. The thermosetting plastic is characterized by comprising the following components in parts by weight: 60-95 parts of thermosetting resin, 5-40 parts of low-shrink additive, 150-300 parts of an inorganic mineral filler, 2-4 parts of an initiator, 0.6-1 part of calcium hydroxide micro powder, 2-6 parts of zinc stearate micro powder and 30-60 parts of glass fiber. In comparison with a conventional thermosetting plastic, the thermosetting plastic can be solidified more rapidly, high strength can be maintained within a wide temperature range, and the flame-retardant effect is good.

Description

technical field [0001] The invention belongs to the technical field of thermosetting plastics, and in particular relates to a fast-curing thermosetting plastic. Background technique [0002] Thermosetting plastics have the characteristics of excellent insulation performance, low density, high strength, and corrosion resistance. Since their birth, thermosetting plastics have been widely used in electronic appliances, vehicle machinery, building materials, etc. Thermoplastic parts. [0003] However, the stability of ordinary thermosetting plastics is not ideal at present, and it is difficult to maintain good strength in a wide temperature range, and it is difficult to meet special requirements. The flame retardant effect is not ideal, and it is easy to deform due to heating for a long time. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a thermosetting plastic that has the characteristics of rapid solidificat...
