[0027] A preparation method of an anti-seepage geotextile material, the preparation method comprising the steps of:
[0028] (1) Stir and mix graphene, modifier and 1.3mol / L hydrogen peroxide at a mass ratio of 8:1:13~15, heat at 80~85°C for 1h, cool to room temperature, let stand for 10min, filter, and wash with water , dry to obtain pretreated graphene;
[0029] (2) Put 1.2mol / L hydrochloric acid, pretreated graphene, and aniline at a mass ratio of 20:6~8:3~5 into the reactor, stir evenly, preheat at 40°C for 20min, and then add pretreated graphene mass 25-35% of auxiliary materials, heat up to 45-50°C, add an initiator of 2-5% aniline mass, stir for 6-8 hours, cool to room temperature, discharge, spray dry, and collect the spray-dried product;
[0030] (3) In parts by weight, take 140-150 parts of water, 30-40 parts of spray-dried product, 15-20 parts of formaldehyde, 10-13 parts of mixture, 7-11 parts of tung oil, and 3-6 parts of additives. Put water, spray-dried produc...
