Preferably, dispersion agent of the present invention is BYK-110 or BYK-104S.
Preferably, defoamer of the present invention is methyl-silicone oil.
Preferably, stopper of the present invention is quinhydrones, toluhydroquinone or copper naphthenate.
Preferably, initiator of the present invention is methylethyl ketone peroxide.
Preferably, coupling agent of the present invention is silane coupling agent.
Another technical problem that the present invention will solve is to provide the preparation method of above-mentioned mould gel coating resin.
For solving the problems of the technologies described above, technical scheme is:
A preparation method for novel die gel coating resin, comprises the following steps:
(1) nanometer silicon carbide, coupling agent are dissolved in toluene, fully disperse rear oil bath to heat with dispersion agent, logical nitrogen protection, stir and shift out material, stratification after 4 hours, by lower sediment thing washing with acetone, at 80 DEG C, vacuum-drying 12 hours, obtains modified Nano silicon carbide;
(2) mixed with unsaturated polyester resin by modified Nano silicon carbide, add aerosil, dispersion agent, defoamer, stopper, initiator, be stirred to without bulk particle, the compound obtaining mixing is mould gel coating resin.
Compared with prior art, the present invention has following beneficial effect:
Nanometer silicon carbide is after the surface modification of coupling agent, can be scattered in resin matrix equably, interface cohesion between silicon-carbide particle with resin matrix is tightr, define the region of intensity higher than resin matrix, when being subject to external force load, these regions by dynamic changes process to the silicon-carbide particle of rigidity, can add that silicon-carbide particle can hinder crack propagation, therefore obvious enhancement be can play, mechanical property and the flexibility of material significantly improved.
