Abstract

The invention relates to the field of wood modification treatment for wood floors, and in particular relates to a mold-proof wood toughening modification treating agent for a wood floor. The mold-proof wood toughening modification treating agent is prepared from the following raw materials in parts by weight: 0.01-0.02 part of colchicine, 4-5 parts of xylitol, 8-10 parts of glycerin, 25-28 parts of sodium carbonate, 4-5 parts of sodium ricinoleic acid n-butyl ester sulfate, 10-12 parts of disodium octoborate, 5-8 parts of phytic acid, 0.5-1 part of cashew nut oil, 350-400 parts of water and 6-8 parts of aid. The prepared modification treating agent has excellent permeation capacity; after components such as colchicine, phytic acid and cashew nut oil permeate into wood, the wood can be endowed with the mold-proof, damp-proof, fresh-keeping and color-protecting effects, the mechanical property of a material can be improved, and the modified wood is natural and bright in color, low in moisture absorption rate, excellent in toughness, resistant to high temperature, and not prone to drying and cracking; the manufactured wood floor is attractive, practical, easy to maintain, and high in market competitiveness.

Description

Mildew-resistant toughening modifying inorganic agent for a kind of timber floor timber

Technical field

The present invention relates to timber floor Wooden modifying process field, be specifically related to mildew-resistant toughening modifying inorganic agent and preparation method thereof for a kind of timber floor timber.

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, core material-timber due to 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, the timber after yet more existing chemical modification methods are processed, in follow-up use procedure, may have a large amount of volatile organic matter discharges, to surrounding environment, can produce harm, 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 mildew-resistant toughening modifying inorganic agent for a kind of timber floor timber, improves serviceability, and to achieve these goals, the technical solution used in the present invention is as follows:

Mildew-resistant toughening modifying inorganic agent for a kind of timber floor timber, it is characterized in that, this modifier is made by the raw material of following weight portion: colchicin 0.01-0.02, xylitol 4-5, glycerine 8-10, sodium carbonate 25-28, castor oil acid butyl ester sodium sulphate 4-5, eight Boratex 10-12, phytic acid 5-8, cashew nut oil 0.5-1, water 350-400, auxiliary agent 6-8;

Auxiliary agent is made by 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.

Mildew-resistant toughening modifying inorganic agent for described a kind of timber floor timber, its preparation method is: first colchicin, xylitol, sodium carbonate, eight Boratexes are mixed with water, after being stirred to material and dissolving completely, add again other leftover materials, with the rotating speed of 1500-1800 rev/min, stir 1-2h, obtain.

Wood modifier advantage of the present invention is: all raw materials are environmental protection composition, do not contain environment and the harmful volatile ingredient of human body, and raw material is easy to get, production cost is lower, colchicin in raw material, phytic acid, after cashew nut wet goods composition infiltrates through in timber, can give wood mould protection against the tide, freshness-keeping and color protection texts, can also improve the mechanical property of material, improve toughness, be difficult for dry and cracked, the modifier that the present invention prepares has good penetration, chemical stability is good, storage convenient transportation safety, timber color and luster after its modification is naturally bright, hydroscopicity is low, toughness is good, high temperature resistant, be difficult for season cracking, the timber floor that making obtains is both artistic and practical, safeguard simple, the market competitiveness is strong.

The specific embodiment

Embodiment

The modifier of the present embodiment by following weight portion (kilogram) raw material make: colchicin 0.01, xylitol 5, glycerine 10, sodium carbonate 28, castor oil acid butyl ester sodium sulphate 5, eight Boratexes 12, phytic acid 8, cashew nut oil 0.5, water 400, auxiliary agent 8; Auxiliary agent is made by the raw material of following weight portion: the aqueous polyurethane emulsion 12 that solid content is 50%, sodium phosphate trimer 3, sodium humate 5, Ludox 2, secondary alcohol APEO 2, Eugenol 0.1, water 30, 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 colchicin, xylitol, sodium carbonate, eight Boratexes are mixed with water, after being stirred to material and dissolving completely, then add other leftover materials, with the rotating speeds of 1800 revs/min, stir 2h, obtain.

The present embodiment be take modifier and is impregnated that to process China fir veneer be example, the China fir veneer of same specification is dried after 10h under 50-60 ℃ 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 ℃ 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 impact flexibility improves 14.8% 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 87.1%, show that the timber after modifier treatment has the resistance leachability having resisted, and the moisture absorption ratio of experimental group China fir is lower, than control group, reduces by 13.2%.
