Description

  The present invention relates to a wood protective coating, and more particularly to a wood protective coating for protecting against decay, mold damage, and white ants.

Conventionally, it is widely known that wood is protected from decay, mold damage, and white ant damage by treating it with a wood protective coating.

Damage degree 0: The weight reduction rate of wood is less than 3% by weight Damage degree 1: The weight reduction rate of wood is from 3% to less than 10% by weight Damage degree 2: The weight reduction rate of wood is from 10% to less than 20% by weight Damage degree 3: The weight reduction rate of wood is 20% by weight or more. In addition, the ant-proof tests of Examples 1 to 5, Reference Example 6 and Comparative Examples 1 to 12 were simultaneously performed, and Examples 7 to 10 and Comparative Examples The ant-proof tests of 13 to 16 were carried out at the same time. The ant-proof tests of Examples 1 to 5, Reference Example 6 and Comparative Examples 1 to 12, and the ant-proof tests of Examples 7 to 10 and Comparative Examples 13 to 16 Were performed separately.

  The wood protective coating of the present invention can be used for various kinds of wood, and in particular, it can be used for various kinds of wood in which molds easily propagate on the surface and bacteria easily propagate in the inside.
