Abstract

The invention discloses a novel timber protective agent comprising the following constituents (by weight percent): nanometer level CuO 7-11%, lemon acid 3-7%, and balancing water.

Description

technical field [0001] The invention relates to a protective agent, in particular to a protective agent for wood. Background technique [0002] The wood preservatives commonly used in the world today are mainly copper, chromium, arsenic (CCA), copper amine (ammonia) quaternary ammonium salt (ACQ) and copper azole (CA), etc., because arsenic and chromium in CCA are toxic substances, easy to Damage to the human body, especially when used indoors, is more harmful to the human body. In the prior art, high-efficiency, low-toxic and environmentally friendly preservatives such as ACQ and CA have begun to replace CCA. The wood protective agents in the prior art are all bactericidal protective components plus ammonia or amine solvents. The bactericidal components and solvent ( Amines, ammonia), in order to melt copper compounds and achieve antibacterial protection, ammonia or amine solvents are essential, which not only consumes a large amount of solvents, but also causes environmen...
