Embodiment 1

[0014] A multifunctional modifier for wood impregnation treatment, its components are proportioned by mass percentage: 12% phenol, 15% formaldehyde, 9% phosphoric acid, 8% melamine, 9% urea, 6% zinc borate %, 10% boric acid, 10% sodium octaborate, 5% copper dimethyl dithiocarbamate, 15% silica sol, 1% fatty alcohol polyoxyethylene ether, the mass concentration of formaldehyde is 35wt% ~ 40wt% , the mass concentration of the phosphoric acid is 20wt%-25wt%, and the silicon dioxide content in the silica sol accounts for 20wt%-30wt%.

[0015] Preparation method: (1), weigh each component according to the weight ratio; (2), add phenol and formaldehyde in the reaction kettle in sequence, turn on the stirrer, slowly add sodium hydroxide solution to adjust the pH value to 11-12, And gradually raise the temperature to 55°C-65°C, then add phosphoric acid and ammonium melamine, continue to heat up to 80°C-85°C, keep warm for 1.5-2 hours, then cool down to 70°C-75°C, then add urea, keep w...

Embodiment 2

[0017] A multifunctional modifier for wood impregnation treatment, its components are proportioned by mass percentage: 8% phenol, 10% formaldehyde, 6% phosphoric acid, 3% melamine, 6% urea, 3% zinc borate %, 5% boric acid, 5% sodium octaborate, 3% copper dimethyl dithiocarbamate, 50% silica sol, 1% fatty alcohol polyoxyethylene ether, the mass concentration of formaldehyde is 35wt% ~ 40wt% , the mass concentration of the phosphoric acid is 20wt%-25wt%, and the silicon dioxide content in the silica sol accounts for 20wt%-30wt%.

[0018] The preparation method is the same as in Example 1.

Abstract

The invention discloses a wood dipping processing multi-function modifier which comprises the following components by mass: 8%-12% of phenol, 10%-15% of formaldehyde, 6%-9% of phosphoric acid, 3%-8% of melamine, 6%-9% of urea, 3%-6% of zinc borate, 5%-10% of boric acid, 5%-10% of sodium octoborate, 3%-5% of dimethyl dithiocarbamate copper, 15%-50% of silica sol, and 0.5%-1% of fatty alcohol polyoxyethylene ether. The beneficial effect is that the wood dipping processing multi-function modifier has being flame retardant, anticorrosive, moth-proofing, enhancing, wear resistant, well erosion resistant and other advantages of, and can significantly improve the application value of processed wood.

Description

technical field [0001] The invention relates to the technical field of wood treatment agents, in particular to a multifunctional modifier for wood impregnation treatment. Background technique [0002] Wood is a renewable, recyclable and naturally degradable green material and biological resource. It has the advantages of beautiful texture, natural color, comfortable texture, good plasticity, and easy processing. It is widely used in interior decoration, furniture manufacturing, Housing construction, exterior decoration and other fields. However, wood also has some defects, such as dry shrinkage and wet swelling due to changes in moisture content, resulting in changes in the size and shape of components and reduction in strength, easy to mildew and decay, easy to be eaten by insects, easy to burn, etc. Especially the artificial fast-growing forest timbers that are very rich in resources in my country at present, in addition to the inherent defects of the above-mentioned timb...
