Description
Technical field
The present invention relates to Wood Property Improvement field, more particularly to a kind of wear-resisting enhanced fast-growing wood of addition modified calcium carbonate
Material modifying agent.
Background technology
Timber and wood materials as social and economic construction in the important means of production, be not only widely used in daily life
In every field, be also widely used for traffic, building and the industrial circle such as space flight.As in world wide, the forest reserves are increasingly
Shortage, particularly precious timber quantity increasingly fall sharply, and the substantial amounts of quick growing species of trees is widely cultivated and meets in global range in recent years
Wood supply.Compared with natural forest, by growth year is short etc., factor is limited the quick growing species of trees, causes early late wood's difference very
Greatly, material is loose, and mechanical property is poor, so not being difficult to height economic used in Furniture manufacture etc. by processing artificial fast-growing forest timber
Added value field.As timber is a kind of natural with porous macromolecular material, by the little, shapes of different fire and different company
The tubular units of understanding and considerate condition are cross-linked and form, and with fluid-pervious, its distinctive vesicular texture is carried for Wooden modifying
Basis is supplied.Physically or chemically modification is carried out to fast-growing forest, the economic value added of fast-growing forest is not only increased, also
Serve the effect of protection rare tree resource.Wooden modifying is referred to using methods such as physics, chemistry and machineries to logs of wood
Manufacturability process is carried out, makes physico-mechanical propertieses such as density of wood, hardness, intensity and dimensional stability etc. obtain good changing
It is kind.Chemical modification is the modified Main Means of fast-growing forest, the selection of the chemical impregnation medicinal liquid wherein in modifying process and dipping
The drying process of material is the research emphasis of Chinese scholars.But the increasing of raising and environmental consciousness with living standards of the people
By force, to human health angle, the residual for how reducing chemical impregnation medicinal liquid in modified material is chemical modification fast-growing forest
Urgent problem, therefore how by fast-growing forest functionalization improvement Study on Integration towards environmental protection and functionalization to be
The modified new direction of this paper and from now on fast-growing forest.
《Composite modifier is to quick growth poplar wood and Chinese toon wood Modification effect and study mechanism》By independently synthesizing low point in one text
The modified nitrogen footpath methyl performed polymer of son is combined with hydroxymethyl-2 dihydroxy-ethylene urea, makes many work(by adding plurality of stable agent
Energy type chemical modifier, has carried out preliminary study to the timber physicochemical property and mechanism of modification after before modified, by impregnation drying
Substantially, heat stability is improved the main mechanical strength improving effect of the modified material after process, while modifying agent is impregnated into wood
When inside material, self-condensation can occur and act on forming tridimensional network, it is higher that modifying agent serves as intensity in wood internal
Implant is especially more obvious to dimensional stability and mechanical property improvement result.Although modified fast growing wood is in mechanics
Increase in performance, but as which has not enough significantly affected fast growing wood furniture, open air out of doors to absorptive reduction
The application of wooden clothing arts, needs further to be modified its composite modifier, it is also desirable to can have other additional properties
To meet the demand to fast growing wood such as outdoor furniture.
The content of the invention
The object of the invention is exactly for the defect for making up prior art, there is provided a kind of addition modified calcium carbonate is wear-resisting enhanced
Fast growing wood modifying agent.
The present invention is achieved by the following technical solutions：
It is a kind of to add the wear-resisting enhanced fast growing wood modifying agent of modified calcium carbonate, it is made up of the raw material of following weight portion：First
Aldehyde 3-3.5, carbamide 2-3, hexamethylenetetramine 1.5-2, maleic anhydride 0.02-0.03, appropriate acetic acid, appropriate ammonia, deionization
Appropriate amount of water, solid content are the hydroxymethyl-2 dihydroxy-ethylene urea 20-23 of 42wt%, Magnesium dichloride hexahydrate 1.5-2, Ludox 10-
11st, Oleum Verniciae fordii 3-4, nano-calcium carbonate 6-7, VAE emulsion 3-4, stearic acid 0.2-0.25, sodium hexameta phosphate 0.3-0.4, pyrophosphoric acid type
Monoalkoxy class titanate esters 0.6-0.7.
Described one kind adds the wear-resisting enhanced fast growing wood modifying agent of modified calcium carbonate, is made up of step in detail below：
（1）Formaldehyde, carbamide, hexamethylenetetramine are put in reactor, maleic anhydride is added, are heated to while stirring completely molten
Solution, the deionized water for adding total amount 1.5-2 times to measure, is heated to 70-80 DEG C, uses acetic acid and ammonia to adjust after stirring reaction 3-4 hour
Section pH value is 7, terminates reaction；
（2）Nano-calcium carbonate is put in drying baker to be dried after 12-16 hours with 100-110 DEG C of temperature and is cooled down, it is stand-by；By Jiao
Phosphatic type monoalkoxy class titanate esters are compound with above-mentioned nano-calcium carbonate, and 50-60 DEG C of dry grinding 60-90 is heated in being put into ball mill
Minute, the deionized water measured of total amount 2-2.5 times is added after discharging, stearic acid, sodium hexameta phosphate is continuously added, turned with 400-500/
The speed stirring 30-40 minutes of part, it is eventually adding Oleum Verniciae fordii, VAE emulsions, ultrasonic disperse 60-90 minutes；
（3）Hydroxymethyl-2 dihydroxy-ethylene urea of the solid content for 42wt% is mixed with Ludox, with 500-600 rev/min of speed
Step is added after stirring 10-15 minutes（1）Step（2）The product for obtaining and remaining residual components, continue ultrasonic disperse 15-20
Minute, obtain final product.
It is an advantage of the invention that：Formaldehyde, carbamide, hexamethylenetetramine are carried out reaction life by certain technique by the present invention
Into performed polymer, then by being compounded with hydroxymethyl-2 dihydroxy-ethylene urea, Ludox, magnesium chloride, can after supersound process
To form colloidal sol type composite modifier, wherein Si-0-Si framing structures play Stabilization to modifier system, by timber
Impregnation process is carried out, timber pickling degree of modification can be significantly improved, improve the rate of body weight gain of timber；Composite modifier can be in wood
It is scattered in the cell wall microcellular structure of timber in material dipping process well, with Wood chemical composition in subsequent heat drying
In cellulose, hemicellulose, lignin etc. there is situ-gel polyreaction, chemical reaction finally makes the sense between them
Group can connect to form covalent bond, and covalent bond is very firm, thus the bending strength of modified fast growing wood, Deflection Modulus of Elasticity and
Parallel-to-grain compressive strength all improves a lot；Simultaneously composite modifier can with the main chemical compositions cellulose of timber, half
There is etherification reaction in cellulose and lignin, such reaction can reduce hydrophilic hydroxy group in timber, so as to significantly reduce wood
Material hygroscopicity.
It is modified that the present invention carries out surface by many nano-calcium carbonates, is then compounded with VAE emulsions etc., by fast-growing
Timber carries out dipping and is modified, and can quickly penetrate into wood internal, can react with the active group in wood matrix,
So as to nano-calcium carbonate is firmly combined, hardness, the comprcssive strength of timber are further increased, so as to reduce timber
Abrasion loss；Good penetrability of the present invention, good stability, leach resistance are good, have good anti-corrosion through its timber for processing
The performance such as fire-retardant, toughened and reinforced, wear-resisting, not easy to crack and durable in use, improves the added value of fast growing wood, expand its
Application in outdoor furniture, outdoor wooden equipment.
