Abstract

The invention relates to an environment-friendly heat-resistant unsaturated polyester electric plastic which consists of an imine modified heat-resistant unsaturated polyester resin, a cross linking system, an enhanced fiber material, a flame resistant system and other accessory agents. According to the weight portions, the unsaturated polyester resin is 25 portions to 40 portions; the cross linking system is 8 portions to 15 portions; the enhanced fiber material is 15 portions to 25 portions; the flame resistant system is 25 portions to 40 portions; other accessory agents are 2 portions to 8portions; other accessory agents refer to one or more of an evocating agent, a mold discharging agent and a colorant. The plastic prepared has the outstanding advantages of good heat resistance and mechanical and electrical performance, simultaneously the indexes of hazardous substance content meet the requirements of European RoHS and is applicable to the manufacturing novel environment-friendlyinsulation parts of electrical equipment.

Description

technical field [0001] The invention belongs to the technical field of electrical insulating materials, and in particular relates to an environment-friendly heat-resistant unsaturated polyester electrical plastic. Background technique [0002] Unsaturated polyester plastics are widely used in the electrical industry due to their excellent mechanical and electrical properties. With the rapid development of the electrical and electronic industry and the improvement of technical levels, there are more and more requirements for the environmental protection, safety and reliability of electrical products. The stricter it is, the corresponding new requirements are put forward for the materials used to manufacture electrical insulation structural parts, especially in terms of harmful substance content, heat resistance, flame resistance, and stability of materials. For example, the "Directive on the Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic E...
