Description
Technical field
Present invention relates particularly to a kind of cross-linking type Wood modifier.
Background technology
Timber is unique reproducible building resource in the four big building materials that society is generally acknowledged, it is each that it occurs nearly in each row
In industry.Dwell from the ape man of ancient times and set and cease to drilling wood to make fire, then to modern household operation, the mankind were never taken out wood
Material, it may be said that the development of the mankind is also accompanied by what timber was carried out.
Along with the development of human civilization, either the various industry of paper-making industry, upholstery, packing business, automobile industry etc. is all
It is unable to do without the figure of woodwork.The consumption of timber is increasing, and China is also become a wood by a forest reserves big country
Material import big country, and domestic timber demand breach increases day by day.In order to alleviate this imbalance between supply and demand, it is rich that country proposes fast-growing
Producing the plan that woods is built, but be as the increase of fast-growing, high-yield woods area, domestic timber breach should reduce, but through investigation
Finding that effect does not so gather effect as anticipation, tracing it to its cause, it is undesirable to be primarily due to the material of fast-growing woods, easily becomes
Shape, density are low, and hardness is the highest, only can be used in some and material is required relatively low industry.So only fast growing wood being entered
Row optimizes, and improves its performance, so could alleviate a current supply and demand difficult problem.
Summary of the invention
The present invention provides a kind of cross-linking type Wood modifier.
In order to solve the problems referred to above, the technical solution adopted in the present invention is such, a kind of cross-linking type Wood modifier,
It is made up of the component of following weight portion: 100 parts of formaldehyde, carbamide 5～15 parts, methyl diphenylene diisocyanate 30～50 parts, alkane
Base silanol 5～10 parts, base catalyst 5～10 parts, organic solvent 100～200 parts and water 1500～2000 parts；
This modifying agent synthesizes as follows:
1) add methyl diphenylene diisocyanate and organic solvent in a kettle., after stirring, add alkyl silicon
Alcohol, reacts 0.5～2 hour under room temperature, adds 1/3～1/2 formaldehyde and be warming up to 60 DEG C, insulation reaction 1～4 hours；
2) carbamide is added in reactor, start stirring, be slowly added to 1/3～1/2 base catalyst, still temperature control is existed
45～60 DEG C, react 1～4 hour；
3) remaining formalin and remaining base catalyst are added in reactor, by still temperature rise to 85 DEG C～90
DEG C, it is incubated 1-2h；
4) divide three equal parts by level, add in three times；Control temperature in the kettle is at 70～80 DEG C, and stream adds first part of water, instead
It is warmed up to 100～120 DEG C after answering 0.5～2 hour react 0.5～2 hour；Being cooled to 70～80 DEG C, stream adds second part of water, instead
After answering 0.5～2 hour, near 40～50 DEG C, add the 3rd part of water, mix uniformly, discharging.
Described alkylsilanol is trimethyl silanol, t-butyldimethyl silane alcohol or decanol.
One or more in sodium hydroxide, potassium hydroxide, ethylenediamine of described base catalyst.
Described organic solvent is acetone, butanone or toluene.
First MDI molecular structure is modified by the present invention with alkylsilanol, forms prepolymer, on the one hand changes it right
The molecular structure claimed, reduces its NCO functional group activity, makes to produce between each molecule in system activity difference, in order to follow-up and water
Reaction produce the different speed of speed, it is to avoid the generation of " polyureas " bits, on the other hand, organic end of organosilicon can be in capillary
Pipe is interior evenly distributed, forms one layer of hydrophobic membrane, suppresses the capillary tube adsorption to water, improves the water-resistance of timber.
Use this modifying agent that artificial forest wood is carried out vacuum pressed impregnation process, the dimensional stability of timber, hard can be made
Degree and water-resistance are largely increased, and modified timber can be widely used for floor, door and window, furniture, outdoor platform deck etc. and produces
The processing of product, is greatly improved the using value of artificial forest wood, to realizing replacing wildwood resource with artificial forest, alleviates China
Timber supply and demand contradiction, it is achieved forest resource sustainable development utilizes significant.
