Description

A kind of timber floor fungus-proof antisepsis inorganic agent used for wood modification

Technical field

The present invention relates to timber floor Wooden modifying process field, be specifically related to a kind of timber floor fungus-proof antisepsis inorganic agent used for wood modification 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 shortcoming such as wet-heat resisting not, seriously limited its scope of application, necessary timber is carried out to some pretreatment, to improve the timber defensive ability/resistance ability of environment to external world, improve environment tolerance level.

Existing method for modifying wood mainly utilizes some physical means, chemical modification agent solution is infiltrated through to timber inside, reach and improve physics, chemical property, the final object that improves its serviceability, but more existing chemical modification methods timber after treatment, in follow-up use procedure, may have a large amount of volatile organic matter discharges, can produce harm 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, to improve its mechanical property, improves serviceability, and possesses effect of fungus-proof antisepsis, and to achieve these goals, the technical solution used in the present invention is as follows:

A kind of timber floor fungus-proof antisepsis inorganic agent used for wood modification, it is characterized in that, this modifier is made up of the raw material of following weight portion: alkali lignin 3-4, sweet orange leaf 2-3, white wine 25-30, BTCA 4-5, menthyl acetate 1-2, sodium molybdate 0.5-1,80% phosphoric acid solution 45-50, white vitriol 1-2, water 350-400, lauric acid amide of ethanol 10-12, auxiliary agent 6-8;

Auxiliary agent is made up of the raw material of following weight portion: the aqueous polyurethane emulsion 10-12 that solid content is 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, being stirred to mixed material dissolves completely, add subsequently secondary alcohol APEO, Eugenol, aqueous polyurethane emulsion, dispersed with stirring 20-30min, add again Ludox, stir after 10min, mixed solution ball milling 1-2h, make stabilizing solution, obtain auxiliary agent.

Described a kind of timber floor fungus-proof antisepsis inorganic agent used for wood modification, its preparation method is: first by alkali lignin, sweet orange leaf, white spirit mixed, airtight placement 4-5 days, subsequently mixed material is filtered, after getting filtrate and water and stirring, add other leftover materials, under the rotating speed of 1500-1800 rev/min, stir 1-2h, 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, the preparation method of this inorganic agent is simply efficient, with soaking in Chinese liquor alkali lignin and sweet orange leaf, can extract active ingredient wherein, give inorganic agent anticorrosive mildewproof effect, also has unique fragrance, have dispelling odor concurrently, improve the effects such as timber color and luster, lignin after immersion and sweet orange leaf are nontoxic, can also recycle, avoid the wasting of resources, again in conjunction with menthyl acetate, sodium molybdate, the raw materials such as phosphoric acid, make modifier of the present invention there is good penetration, hygroscopicity is little, chemical stability is good, have concurrently anticorrosion, mildew-resistant, the multiple efficacies such as fire-retardant, timber color and luster after modification is naturally bright, intensity, the mechanical properties such as toughness obtain certain lifting, the timber floor that making obtains is durable in use, the market competitiveness is strong.

Detailed description of the invention

Embodiment

The modifier of the present embodiment by following weight portion (kilogram) raw material make: alkali lignin 4, sweet orange leaf 2, white wine 30, BTCA 5, menthyl acetate 2, sodium molybdate 0.5,80% phosphoric acid solution 50, white vitriol 2, water 380, lauric acid amide of ethanol 12, auxiliary agent 8; Auxiliary agent is made up of the raw material of following weight portion: aqueous polyurethane emulsion 12, sodium phosphate trimer 3, sodium humate 5, Ludox 2, secondary alcohol APEO 2, Eugenol 0.1, water 30 that solid content is 50%, its preparation method is: first sodium phosphate trimer, sodium humate are mixed with water, being stirred to mixed material dissolves completely, add subsequently secondary alcohol APEO, Eugenol, aqueous polyurethane emulsion, dispersed with stirring 30min, add again Ludox, stir after 10min, mixed solution ball milling 2h, make stabilizing solution, obtain auxiliary agent.

The preparation method for modifier of the present embodiment is: first by alkali lignin, sweet orange leaf, white spirit mixed, airtight placement 5 days, filters mixed material subsequently, after getting filtrate and water and stirring, add other leftover materials, under the rotating speed of 1800 revs/min, stir 2h, to obtain final product.

The present embodiment impregnates and processes China fir veneer as example taking modifier, the China fir veneer of same specification is dried after 10h under 50-60 DEG C of condition, be divided into two groups, experimental group is soaked in synthermal modifier, in vacuum is-0.1MPa, pressure is to impregnate 2h under 0.5MPa condition, take out, after the washing of surface, in natural environment, be dried 7 days, finally under 50-60 DEG C of condition, cure, keep moisture content at 5-6%; Control group is left intact. Two groups of veneers enter subsequent processes, make laminated flooring.

Experimental group China fir veneer after modification and undressed control group China fir veneer carry out respectively performance test, result shows, experimental group China fir compression strength improves 18.8% compared with control group timber, at wood surface inoculation wood after mould and black mould, experimental group China fir veneer surface clean is without mycelia, otherwise control group China fir surface from mildewing is serious; The anti-lixiviate value of experimental group China fir veneer reaches 87.6%, shows that the timber after modifier treatment has the resistance leachability having resisted, and the variation of the moisture absorption ratio of experimental group China fir is little, than control group rate of change≤2.0%.
