4H
4ClNOS; The molecular formula of said MIT is C
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) earlier water is injected in the preparing tank;
(2) in water, add chromium trioxide according to proportioning again, add cupric oxide then while stirring, 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, add the card pine according to proportioning again, obtains said CCAK anticorrisive agent behind the stirring reaction.
Preferable, in the step (2), adopt the form that slowly adds during said adding cupric oxide.
Preferable, in the step (3), the said 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 obtains through adding the loose anticorrisive agent of a certain amount of card, and said card pine not only can join among the CCA, and mildew-resistant own, prevents that color changeable effect is good, also has the favorable environment protection ability.CCAK anticorrisive agent of the present invention; Cupric oxide in its solute, chromium trioxide and diarsenic pentoxide and the intermiscibility of card pine in water are good; Has excellent coordination property; Especially stable in the aqueous solution of cupric oxide, chromium trioxide and the diarsenic pentoxide of acidity; And each component is worked in coordination with onset; Its fungicidal properties has obtained further raising and reinforcement, can but also have favorable environment protection; The fungicidal properties of CCAK anticorrisive agent of the present invention is compared with traditional CCA anticorrisive agent and is improved and further improvement, and compatibility, stability are all fine between each component.
CCAK anticorrisive agent of the present invention can be widely used as timber preservative.
