Embodiment Construction

[0011] The embodiment is prepared by mixing one or two or more mixtures of copper carbonate, copper hydroxide, and copper bicarbonate with dimethyl dodecyl benzyl ammonium chloride, allethrin, and ammonia . The optimum proportioning that adopts is (weight ratio):

[0012] Copper salt 25%

[0013] Dimethyldodecylbenzyl ammonium chloride 35%

[0014] Allethrin 8%

[0015] Ammonia 32%

[0016] When in use, this preparation is mixed with an appropriate amount of water, soaked in the wood or wooden products, wait until it is completely absorbed, and then dry it.

Abstract

A timber preservative is formed by mixing cupric salt, dimethyl dodecyl benzyl ammonium chloride, allethrin and ammonia, wherein the cupric salt can undergo complexation and solidification with timber, thereby having a long-term poisonous effect on bacteria; the benzyl ammonium chloride is used as a bactericide; and the allethrin plays a role in deinsectization and killing insect eggs. Therefore, the timber preservative has excellent preservative effects and is avirulent to human body.

Description

technical field [0001] The present invention is a kind of chemical preparation for wood preservative treatment. Background technique [0002] Wood preservatives are widely used in the antiseptic treatment of wood and wood products. The current wood preservatives are CCA preservatives, which contain harmful substances such as arsenic and chromium. They are toxic and cannot be degraded, and are easy to cause harm to the human body and the environment. Contents of the invention [0003] The purpose of the present invention is to provide a non-toxic and efficient wood preservative. [0004] The present invention is formed by mixing copper salt, dimethyl dodecyl benzyl ammonium chloride, allethrin and ammonia water, and its proportioning ratio is: (weight ratio) [0005] Copper salt 20-30% [0006] Dimethyl dodecyl benzyl ammonium chloride 30—40% [0007] Allethrin 5-10% [0008] Ammonia 30-40% [0009] Wherein the copper salt is one or a mixture of two or more of copper c...
