Ester and Isosorbide-5-Nitrae butanediol are fitted into equipped with nitrogen protection in agitator, condenser pipe, four mouthfuls of reactors of thermometer, is led to, and add two bays
Sour dibutyl tin catalytic reaction, is to slowly warm up to 70-80 DEG C, reacts 1-2h, then sequentially adds dimethicone, asphalt mixtures modified by epoxy resin
Fat, trimethylolpropane, dioctyl phthalate, bentonite, continue stirring reaction, are subsequently adding acrylate monomer, and
Ethyl acrylate is added simultaneously, continues to be uniformly mixed, you can obtain modified polyurethane resin.
6. composite water permeable brick according to claim 1, it is characterised in that：The specific preparation technology of the composite water permeable brick
For：
（1）, by sieve, will be then placed in agitator after natural color stone grinding, stirred together during composite fibre is delivered into agitator
Mix uniform, mixing time is 1-2h, stand-by；
（2）Modified polyurethane resin is placed in agitator, to adding auxiliary agent in agitator and stirring, 30-50min is stirred, treated
With；
（3）By step（1）In the mixture for preparing deliver to step（2）Agitator in, stir 10-30min, stir
Afterwards, resin base layer material is obtained；
（4）In injecting material into press die, and consolidated with wooden stick, compacting obtains resin base layer；
（5）Repeat step（1）-（3）Operation obtain resin base colorful surface layer material, the resin base colorful surface layer that then will be obtained
Material injection step（4）In in the resin base layer that obtains, compacting obtains being covered in the resin base colour plane in resin base layer
Layer；
（6）Then curing process is carried out, taking-up obtains water-permeable brick embryo material, the water-permeable brick embryo material after solidification is carried out into water seasoning,
Band finished product water-permeable brick can be obtained within 20-28 days.
7. composite water permeable brick according to claim 6, it is characterised in that：When resin base layer is prepared, natural color stone is selected
Dimmed natural color stone, when resin base colorful surface layer is prepared, natural color stone is using colored natural color stone.
