Technical field

The present invention relates to timber floor Wooden modifying process field, be specifically related to a kind of timber floor Wooden modifying inorganic agent containing nano titanium oxide and preparation method thereof.

Background technology

Timber floor is common fitment material for family, mainly comprise the kinds such as solid wooden floor board, laminated flooring, solid wooden compound floor, due to the core material-timber of timber floor, it is biological material, itself there is inflammable, perishable, yielding, the not shortcoming such as wet-heat resisting, seriously limit its scope of application, more necessary pretreatment are carried out to timber, to improve the defensive ability/resistance ability of timber environment to external world, environmental protect tolerance level.

Existing method for modifying wood mainly utilizes some physical means, chemical modification agent solution is infiltrated through wood internal, reach and improve physics, chemical property, the object of final its serviceability of raising, but the timber after more existing chemical modification method process, a large amount of Volatile organic emissions may be had in follow-up use procedure, harm can be produced to surrounding environment, also there is inorganic agent high expensive, performance is not lasting, affect the shortcomings such as decorate properties, in the urgent need to developing the Wood modifier of the novel environment-friendly high-efficiency of a class, fundamentally improve the serviceability of timber floor, improve the shortcoming on Traditional Wood floor.

Summary of the invention

The object of the invention is to provide a kind of timber floor timber modifier, and to improve the mechanical property of timber, improve use value, to achieve these goals, the technical solution used in the present invention is as follows:

A kind of timber floor Wooden modifying inorganic agent containing nano titanium oxide, it is characterized in that, this modifier is made up of the raw material of following weight portion: tarragon 2-3, derris root 1-2, Macrogol 200 4-5, white wine 10-12, APEO 2-3, Di-phosphorus pentonide 3-5, KI 5-8, diammonium hydrogen phosphate 45-50,80% BAS 20-25, nano titanium oxide 0.1-0.2, water 350-400, auxiliary agent 6-8;

Auxiliary agent is made up of the raw material of following weight portion: solid content is the aqueous polyurethane emulsion 10-12 of 50%, sodium phosphate trimer 1-3, sodium humate 4-5, Ludox 2-3, secondary alcohol APEO 1-2, Eugenol 0.1-0.2, water 30, its preparation method is: first by sodium phosphate trimer, sodium humate mixes with water, be stirred to mixed material to dissolve completely, add secondary alcohol APEO subsequently, Eugenol, aqueous polyurethane emulsion, dispersed with stirring 20-30min, add Ludox again, after stirring 10min, mixed solution ball milling 1-2h, make stabilizing solution, obtain auxiliary agent.

Described a kind of timber floor Wooden modifying inorganic agent containing nano titanium oxide, its preparation method is:

(1) first tarragon, derris root mixing are added in white wine, airtight placements 4-5 days, subsequently by mixed material filtration, get filtrate and water stirs for subsequent use;

(2) by after nano titanium oxide and Di-phosphorus pentonide mixing and stirring, add step (1) gained material and other leftover materials, under the rotating speed of 1500-1800 rev/min, stir 2-3h, to obtain final product.

Wood modifier advantage of the present invention is: all raw materials are environmental protection composition, can not work the mischief to environment and human body, and raw material is easy to get, production cost is lower, and the preparation method of this inorganic agent is simply efficient, with soaking in Chinese liquor tarragon and derris root, active component wherein can be extracted, effectively infiltrate through wood internal, give inorganic agent aromatic odor and mould-proof disinsectization effect, tarragon after process and derris root nontoxic, can also resource reutilization; After the raw materials such as nano titanium oxide, KI, diammonium hydrogen phosphate infiltrate through wood internal, the durability of timber can be improved, good stability of the dimension, not easily convergent-divergent, has the composite efficacies such as fire-retardant, sterilization concurrently, and the timber natural in color after modifier treatment becomes clear, texture is unaffected, the mechanical property such as intensity, toughness obtains certain lifting, and make the fire-retardant mildew-resistant of timber floor, durable in use obtained, the market competitiveness is strong.

Detailed description of the invention

Embodiment

The modifier of the present embodiment is obtained by the raw material of following weight portion (kilogram): tarragon 3, derris root 2, Macrogol 200 5, white wine 12, APEO 3, Di-phosphorus pentonide 5, KI 8, diammonium hydrogen phosphate 50,80% BAS 25, nano titanium oxide 0.1, water 400, auxiliary agent 8; Auxiliary agent is made up of the raw material of following weight portion: solid content is aqueous polyurethane emulsion 12, sodium phosphate trimer 3, sodium humate 5, Ludox 2, secondary alcohol APEO 2, Eugenol 0.1, the water 30 of 50%, its preparation method is: first sodium phosphate trimer, sodium humate are mixed with water, be stirred to mixed material to dissolve completely, add secondary alcohol APEO, Eugenol, aqueous polyurethane emulsion subsequently, dispersed with stirring 30min, add Ludox again, after stirring 10min, mixed solution ball milling 2h, make stabilizing solution, obtain auxiliary agent.
