Abstract

The invention relates to a resin for molding motor parts. The resin comprises 22-35 parts of ethylene glycol, 15-22 parts of propylene glycol, 46-64 parts of adipic acid, 5-10 parts of phthalic anhydride, 0.001-0.003 part of dibutyltin oxide and 1-5 parts of dicyclopentadiene. A preparation method of the resin comprises the following steps: (1) the ethylene glycol, propylene glycol, adipic acid, phthalic anhydride, dibutyltin oxide and dicyclopentadiene are sequentially added into a reaction kettle, and are reacted; and (2) the reaction is carried out for 48 h, the intermediate acid value is detected to be 48 + / - 1, and the obtained solution is immediately cooled to 180 DEG C, and undergoes discharging dilution by using a dilution kettle connected with the reaction kettle. The resin meetsthe demands of the motor parts for the mechanical strength and insulation properties.

Description

technical field [0001] The invention relates to a molding resin, in particular to a resin for motor parts. Background technique [0002] Composite materials, like other traditional materials, can be further made into various structures and types of final products by many different processing methods or molding methods to meet different application requirements. Among these molding methods, the SMC / BMC molding process is a mechanized operation with a high degree of automation, and is especially suitable for producing high-quality products with high dimensional accuracy requirements, large batches, and excellent appearance. The SMC / BMC process currently occupies a pivotal position in the composite material industry in developed countries in the world, and has a tendency to replace most other processing technologies. [0003] At present, the domestic mold pressing market has basically formed a professional enterprise structure after decades of development, enterprise reorganiz...
