Wood preservative with tea polyphenols

Abstract

The invention discloses a wood preservative with tea polyphenols. The problems that in the prior art, the preservative performance of a preservative is greatly affected in the humid environment, and the service life is shortened are solved. The wood preservative is prepared from the following substances in parts by weight: 12-14 parts of boric acid, 2-4 parts of disodium octaborate, 10-12 parts ofdicyandiamide, 6-8 parts of sodium fluoride, 42-50 parts of ammonium sulfate, 2-4 parts of copper oxide, 2-5 parts of the tea polyphenols and 1-3 parts of carboxymethylcellulose. When the preservative prepared from the various components in proportion is applied to wood, the purposes of inhibiting and killing indoor bacteria and expelling insects can be effectively realized, and the effect of removing formaldehyde in the wood and the indoor space to purify air can also be realized; and a wood board treated through the wood preservative can emit the fragrant tea smell, the refreshing effect isbetter realized, the time of duration is long, and the odor volatilization time can be up to 3 years or above.

Description

Technical field [0001] The invention relates to a preservative, in particular to a wood preservative with tea polyphenols. Background technique [0002] Wood is one of the important raw materials for national construction and people's daily necessities, such as building materials and industrial materials. With the improvement of people's living standards, the demand for wood is also increasing. Wood is a natural organic material with obvious biological characteristics, and is easily attacked by organisms such as bacteria, insects, and marine borers. Therefore, the long-term use of wood, especially long-term outdoor use, is greatly restricted. [0003] The decaying organisms can cause the decay of wood and cause it to be destroyed. Before use, according to different application environments, selecting appropriate preservatives and performing appropriate treatments can effectively delay wood decay. The forest resources that can be harvested and used in our country are very limite...
