The invention discloses a germicidal negative-radical waterproof
coating, which is characterized by being prepared from the following raw materials in parts by weight: 0.2-0.4 part of a dispersant EFKA4010, 0.1-0.2 part of a defoaming agent BYK-390, 0.2-0.3 part of a defoaming agent BYK-057, 0.1-0.3 part of a
dodecylbenzene sulfonic acid, 40-50 parts of an organosilicone modified
polyester resin, 10-15 parts of an
acrylic resin, 6-8 parts of a hexamethoxymethyl
melamine resin, 4-6 parts of
rutile titania, 2-4 parts of
silicon sol, 0.3-0.5 part of
methyl cellulose, 0.3-0.5 part of palm
wax, 3-6 parts of
barium sulfate, 4-5 parts of
mica powder, 1-2 parts of a matting agent, 0.2-0.4 part of an anti-scratch agent BYK-980, 7-9 parts of S-150, 3-5 parts of
diacetone alcohol, 5-7 parts of
butyl acetate, 0.5-1.0 part of quizalofop-p-ethyl, and 5-7 parts of a negative-radical additive. According to the
coating disclosed by the invention, the added
silicon sol is used for enhancing the
hardness and
wear resistance of a coated film, the added anti-scratch agent is used for improving the scratch resistance of the coated film, the added
rutile titania achieves good bacteriostatic and germicidal effects and the like on the soil, and the added negative-radical additive has a good negative-radical effect and has no
adverse effect on plants.
