[0026] Example 1
[0027] A manufacturing method of epoxy vinyl ester microcrystalline composite resin includes the following steps:
[0028] (1) Weigh 80 parts of epoxy vinyl ester resin, 30 parts of 40 mesh acid-washed quartz sand, 5 parts of zinc stearate, defoamer composed of 70% polyoxypropylene glycerol ether and 30% tetraethyl silicon 3 parts, 3 parts of organopolysiloxane with a molecular weight of 5000;
[0029] (2) Put the weighed raw materials in step (1) into a mixing tank and mix and stir for 10 minutes;
[0030] (3) Add all the raw materials in step (2) to a high-speed disperser, and disperse them at a speed of 1000 rpm for 15 minutes;
[0031] (4) Put all the raw materials in step (3) into the grinder and grind for 10 minutes;
[0032] (5) All the raw materials in the sub-packing step (4) are placed in a cool and dry place for later use.
