Embodiment 1

[0012] A wood preservative containing nano-titanium dioxide, its components are proportioned by mass percentage: 25% silica sol, 3% isooctyl phosphate, 5% nano-titanium dioxide, 8% potassium iodide, and 2% fatty alcohol polyoxyethylene ether , diammonium hydrogen phosphate 15%, zinc borate 8%, ammonium heptamolybdate 4%, disodium octaborate tetrahydrate 7%, sodium polyacrylate 1%, polyethylene glycol 2%, water 20%, the silica sol The silicon dioxide content in it accounts for 25wt%~30wt%.

[0013] Preparation method: (1), weigh each component according to the weight ratio; (2), mix isooctyl phosphate, nano-titanium dioxide, fatty alcohol polyoxyethylene ether and water evenly, then add silica sol and potassium iodide, and Heat up to 60°C-85°C, stir at a speed of 1500-1800r / min for 20-50min, then add other remaining components, and stir at a temperature of 35°C-50°C at a speed of 60-120r / min for 10-30min. Then cool to room temperature to obtain a wood preservative containing n...

Embodiment 2

[0015] A wood preservative containing nano-titanium dioxide, its components are proportioned by mass percentage: 15% silica sol, 1% isooctyl phosphate, 2% nano-titanium dioxide, 5% potassium iodide, and 1% fatty alcohol polyoxyethylene ether , Diammonium hydrogen phosphate 10%, zinc borate 4%, ammonium heptamolybdate 2%, disodium octaborate tetrahydrate 6%, sodium polyacrylate 2%, polyethylene glycol 2%, water 50%.

[0016] The preparation method is the same as in Example 1.

Abstract

The invention discloses a titanium dioxide-containing wood preservative which comprises the following components by mass: 15%-25% of silicon sol, 1%-3% of isooctanol phosphate, 2%-5% of nano titanium dioxide, 5%-8% of potassium iodide, 1%-2% of fatty alcohol polyoxyethylene ether, 10%-15% of diammonium hydrogen phosphate, 4%-8% of zinc borate, 1%-4% of ammonium heptamolybdate, 4%-7% of disodium octaborate tetrahydrate, 0.5%-2% of sodium polyacrylate, 1%-2% of polyethylene glycol (PEG) and 20%-50% of water. The beneficial effect is that the titanium dioxide-containing wood preservative has good permeability, strong erosion resistance, low cost and other advantages, has good sterilization and anti-corrosion effect on treated wood, gives wood the effects of flame retardance, smoke suppression, enhancement, wear resistance, low tendency to crack, and the like, and the wood durability and dimensional stability and other functions are improved.

Description

technical field [0001] The invention relates to the technical field of wood treatment agents, in particular to a wood preservative containing nano titanium dioxide. Background technique [0002] Wood and its products are widely used in interior decoration, furniture manufacturing, house construction and exterior decoration, but they have problems such as shrinkage and swelling, poor dimensional stability, easy mildew and decay, easy to be eaten by insects, and easy to burn. The earth affects its application effect in various fields. In order to obtain high-performance and high-value-added wood products, it is usually necessary to carry out necessary functional improvements on the wood before it is used, so as to overcome its deficiencies in flame retardancy and anticorrosion. Contents of the invention [0003] The object of the present invention is to provide a wood preservative containing nano-titanium dioxide, which has the functions of flame retardancy, sterilization a...
