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 8 portions; 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-friendly insulation parts of electrical equipment.
Description
Technical field
The invention belongs to the insulating material technical field, particularly a kind of environment protection type heat resisting unsaturated polyester electrical plastic.
Background technology
Unsaturated polyester plastic is with its excellent mechanical electric performance widespread use in electrical apparatus industry, the raising with state of the art of developing rapidly along with electronic enterprises, environmentally friendlyization, security and reliability requirement to electric equipment products are more and more tighter, corresponding to being used to make the material of electrical apparatus insulation structural part, new requirement has also been proposed, particularly the harmful substance contents of material, thermotolerance, flame resistivity and stable aspect require very high." using some objectionable impurities instruction (2002/95/EC number instruction of European Union is called for short the RoHS instruction) " as European Union's issue about restriction in electric appliance and electronic equipment.According to this instruction, from on July 1st, 2006, all electric appliance and electronic equipment of selling on European Union market must ban use of lead (Pb), mercury (Hg), cadmium (Cd), sexavalent chrome heavy metals such as (Cr) and polybromodiphenyl ether (PBDE) and Polybrominated biphenyl objectionable impuritiess such as (PBB).According to this global evolution trend, China also in issuing and implementation on March 1st, 2007 " electronics and IT products pollution control management way ", limits above-mentioned 6 kinds of harmful elements to some extent.But original unsaturated polyester plastic can not satisfy these new technical requirementss, need improve the needs that its performance could adapt to the electronic apparatus development and application by synthetic and modification.
