Water-borne wood modifier and preparation method thereof

Abstract

The invention provides a water-borne wood modifier. The water-borne wood modifier is prepared from following components in parts by weight: 1-150 parts of an isothiazolinones compound, 1-300 parts of an organic solvent, 1-150 parts of a cosolvent, 1-250 parts of carbamic acid ester, 1-700 parts of a nonionic surfactant, 1-100 parts of an ionic surfactant, 1-1000 parts of a coloring agent and 1-5000 parts of water. A preparation method of the water-borne wood modifier comprises the following steps: dissolving the isothiazolinones compound into the organic solvent and the cosolvent; secondly, compounding a mixture with iodopropynyl butylcarbamate to form an oil phase; sequentially adding the nonionic surfactant, an additive and an ionic surfactant into the oil phase to prepare missible oil; diluting the missible oil with the water; then adding the coloring agent to prepare the water-borne wood modifier. The modifier is water-borne and has the characteristics of high stability, and high permeability and uniform dying on woods. The pharmaceutical compositions and the coloring agent have excellent compatibility.

Description

technical field [0001] The invention relates to the technical field of dyeing agents, in particular to an antiseptic, anti-mildew and staining water-borne wood modifier and a preparation method thereof. Background technique [0002] Wood is a naturally renewable, recyclable, and degradable biomaterial with beautiful texture, high strength-to-weight ratio, excellent environmental characteristics and workability, and is loved by people, so it is widely used in production and life. However, with the dwindling of natural forest resources, wood products processing raw materials are gradually turning to plantation forest resources. The fast-growing plantation wood is generally loose in material, low in density, easy to rot and mildew, therefore, it is necessary to carry out certain anti-corrosion treatment on the fast-growing plantation wood. Moreover, the wood market has an increasing demand for color diversity and imitation of precious wood. Proper dyeing of anti-corrosion trea...

Problems solved by technology

The most common ones are chromated copper arsenate (CCA), ammonium-soluble quaternary ammonium copper (ACQ) and copper azole (CA), etc. The color of such preservative-treated materials is relatively single, so it is more difficult to dye preservative wood. Large, it is bound to greatly increase the cost of dyeing, seriously affecting the decorative effect of wood products

Therefore, organic preservatives provide a more suitable choice. Although there are currently researches on related organic preservatives, alcohols or highly toxic organic solvents are usually used, such as the invention patent CN102934635A, which mainly uses alcohol solvents. In the actual production and application process There is a certain risk, and if the main solvent is an alcohol solvent, usually due to its good water solubility, the formula is prone to precipitation, crystallization, etc.
