Problems solved by technology

In order to make the wood meet the anti-biological attack and waterproof properties at the same time, the existing technology needs to dry and treat the wood multiple times, and one treatment process cannot meet the requirements.
In addition, almost all water-borne preservatives in the domestic and foreign markets currently contain copper elements, and the surface of the treated wood is green, which not only affects the decorative effect of the wood, but also limits the application range of the protective treated wood.

Abstract

The invention belongs to the field of wood processing, and particularly relates to a wood preservative and waterproof coloring agent, and a preparation method and an application of the coloring agent. The wood preservative and waterproof coloring agent comprises the following ingredients by mass percent: 3.5-10% of alkaline preservative, 3-7% of paraffin emulsion, 0.5-2% of azo reactive dye and 81-93% of water, and the above ingredients are mixed uniformly, thereby obtaining the wood preservative and waterproof coloring agent. The preservative effect of the wood preservative and waterproof coloring agent can reach a strong corrosion resistance grade; a termite decaying grade is zero; a water repellency rate of the wood can reach 53.66%; the wood can be endowed with multiple surface colors such as tawny, hazel, puce and reddish brown; the colors of multiple precious wood such as teak and rosewood can be imitated; attractive and decorative effects required by high-grade decoration and renovation places can be met; and the additional value and the application range of the wood are improved and broadened significantly.

Description

technical field [0001] The invention belongs to the field of wood processing, and in particular relates to a wood antiseptic and waterproof staining agent as well as its preparation method and application. Background technique [0002] my country is a country with scarce timber resources. With the continuous development of social economy, people have higher and higher requirements for living conditions and living environment, and the demand for wood is increasing. It is estimated that my country's timber gap will exceed 100 million m by 2020 3 . In addition, wood is a biomass material with a limited lifespan. In the process of wood application, what seriously shortens its service life is fungus, termites and other biological infestation. Taking masson pine as an example, it will completely rot if it is left in contact with the soil for one year in Guangdong. In addition, the deformation and cracking of wood not only directly affect the performance of wood, but also acce...
