4h
5nOS.
Wherein the part by weight of CIT and MIT is (2.5～4.0): 1.
The preparation method of CCAK anticorrisive agent of the present invention, comprises the steps:
(1) first water is injected in preparing tank;
(2) according to proportioning, in water, add chromium trioxide again, then add while stirring cupric oxide, react and obtain mixed liquor after at least 3 hours;
(3) according to As
2o
5the mol ratio of middle As adds arsenic acid in the mixed liquor of step (2) gained, then adds Kathon CG according to proportioning, obtains described CCAK anticorrisive agent after stirring reaction.
Preferably, in step (2), described in adopt the form slowly adding while adding cupric oxide.
Preferably, in step (3), the described reaction time is 0.3～0.5 hour.
The beneficial effect that CCAK anticorrisive agent of the present invention has:
CCAK anticorrisive agent of the present invention is by adding a certain amount of Kathon CG anticorrisive agent to obtain, and described Kathon CG not only can join in CCA, and mildew-resistant own, anti-color changeable effect are good, also have good environmental-protecting performance.CCAK anticorrisive agent of the present invention, cupric oxide in its solute, chromium trioxide and diarsenic pentoxide and the Kathon CG intermiscibility in water is good, there is excellent coordination property, especially stable in the aqueous solution of acid cupric oxide, chromium trioxide and diarsenic pentoxide, and each component is worked in coordination with onset, its fungicidal properties has obtained further raising and reinforcement, but also has good environmental-protecting performance; The fungicidal properties of CCAK anticorrisive agent of the present invention is compared with traditional CCA anticorrisive agent and is improved and further improves, and between each component, compatibility, stability are all fine.
CCAK anticorrisive agent of the present invention can be widely used as timber preservative.
