1. , a kind of making method of polyurethane colour liquid water-proofing material is characterized in that comprising in the above-mentioned polyurethane coloured liquid water-proof material component (A) and component (B):

  • Component (A) is by injecting stirred tank by gross weight than (down together) 60 to 90% polyvalent alcohol and 10 to 40% tolylene diisocyanate (TDI), stirred 2 to 4 hours at 70 to 110 ℃

    , building-up reactions generation component (A);

    Component (B) is by three or three dichloros, four or four methylene dianilines (MoeA) of 1-8%, 0.5 to 2% tetrahydroxypropyl ethylenediamine (N403), the polyether glycol (N330) of 2-8%, 0.2 to 1% UV light absorber, 0.2 to 1% anti-aging agent, 20 to 40% talcum powder, 40 to 80% the multi-thread oil of high temperature, after grinding, put into stirred tank, be incubated under 90 to 130 ℃

    of temperature of heating under vacuum, mixed 3 to 5 hours, and made component (B);

    During use 10 to 40% component (A) is poured in the stirred pot with 60 to 90% component (B), add 0.1 to 15% zinc naphthenate catalyzer again, stirred 2 to 4 minutes, be poured on the place that to lay, thickness is decided according to design requirements, wipe off with scraper plate, made product of the present invention in static 10 to 30 hours.
