Preparation method for motor slot wedge

[0020] A preparation method of a motor slot wedge, the slot wedge is composed of the following components by weight percentage: 14% of unsaturated polyester resin, 0.3% of internal mold release agent, 0.8% of tert-butyl peroxybenzoate, diethyl peroxide Benzoyl 1.0%, talcum powder 5%, alkali-free glass fiber 30%, and the balance is iron-nickel alloy powder. The preparation method comprises the following steps:

[0021] (1) Prepare unsaturated polyester resin, internal mold release agent, tert-butyl peroxybenzoate and dibenzoyl peroxide in proportion to make adhesive at 60°C, then add talc powder and reduced iron powder into the adhesive and stir well;

[0022] (2) impregnating the non-alkali glass fiber with the above adhesive;

[0023] (3) Heating the mold to 210°C, drawing speed 1.40r / min; pultruding the alkali-free glass fiber impregnated with the adhesive through the mold;

[0024] (4) Cooling and cutting;

[0025] (5) Grinding the cut wedge;

[0026] (6) Paint the surf...
