Abstract
The present invention relates to a kind of furfuryl alcohol resin for Wooden modifying and optimize liquid, including the component of following weight portion: include the component of following weight portion: furfuryl alcohol 50% 70%, maleic anhydride 5% 10%, stabilizer 1% 5%, solvent 5% 10% and water 20% 45%.This timber optimizes liquid maleic anhydride as catalyst, it is prepared furfuryl alcohol resin timber as stabilizer and ethanol and methanol as compounded organic solvent in conjunction with sodium carbonate and optimizes liquid, make improved wood have the advantages such as significant anti-corrosive properties, resistance leachability, dimensional stability simultaneously, realize the superior of low-grade timber, improve utilization rate and the service life of timber.The formula of this optimization liquid is nontoxic, Halogen, good environmental protection, belongs to environment-friendly type Wooden modifying and processes optimization liquid, does not produces environment and pollute during producing and using.The resistance leachability of timber, dimensional stability, antiseptic property and the mechanical performance modified by this optimization liquid are all greatly improved.
Description
Technical field
The present invention relates to timber processing Techniques of preserving field, be particularly used for the furfuryl alcohol resin optimization of Wooden modifying
Liquid.
Background technology
Timber is as one of the big basic material in world today four (plastics, steel, cement, timber), and it is uniquely may be used
Regenerated resources, have renewable, recycling and can the feature of natural degradation.Along with economic development and living standard not
Disconnected raising, society is increasing to timber products demand, and the imbalance between supply and demand of timber becomes increasingly conspicuous, except the existing people of Appropriate application
Outside work forest timber, in the service life of prolonging wood, alleviate the important channel of timber supply and demand contradiction beyond doubt.
Artificial forest wood is owing to fast growth, wood dimensional stability and mechanical property are generally than wildwood timber
Difference, it is difficult to meeting the demand of wood working industry, therefore artificial forest wood needs to use performance modifier to be modified at optimization
Reason.Furfuryl alcohol resin improved wood is by full-cell process, will contain the bran of catalyst and stabilizer with water or Organic Alcohol for solvent
Alcoholic solution immerses wood internal.Furfuryl alcohol is made to complete solidification in wood cell, intercellular substance even cell wall by heating.Furfuryl alcohol
Resin modified technology can dramatically increase timber antibiont aggressivity, improve dimensional stability, reduction equilibrium moisture content and increase
Case hardness.Furfuryl alcohol resin improved wood is producing, is using and environmental friendliness in waste procedures, makees people, animal almost without poisoning
With.
Summary of the invention
It is an object of the invention to provide a kind of furfuryl alcohol resin for Wooden modifying and optimize liquid, this optimization liquid can effectively carry
The dimensional stability of high disposal material, hardness, density and water-resistance.
To achieve these goals, the technical solution used in the present invention is, a kind of furfuryl alcohol resin for Wooden modifying is excellent
Change liquid, including the component of following weight portion: furfuryl alcohol 50%-70%, maleic anhydride 5%-10%, stabilizer 1%-5%, solvent 5%-10% and
Water 20%-45%.
As a modification of the present invention, described furfuryl alcohol uses furfural catalytic hydrogenation to prepare, and described furfural uses rice husk, wheat
One or more raw materials mixing in shell, rape stalk, corn straw, corn cob, bagasse, sunflower straw and cotton seed hulls
Preparation.
As a modification of the present invention, described stabilizer is in sodium carbonate, Borax, sodium hydroxide and sodium bicarbonate
Plant or combination of the above thing.
As a modification of the present invention, described solvent is one or more compositionss in methanol, ethanol and acetone.
As a modification of the present invention, described water is tap water or softens pure water, it is preferred to use softness number is 7.15
The softening pure water of left and right.
As a modification of the present invention, described stabilizer uses sodium carbonate.
As a modification of the present invention, described solvent uses that methanol and ethanol are compounding to be prepared, wherein methanol and ethanol
Weight ratio is 1:1-2.5.
Relative to prior art, the present invention is main dispensing with furfuryl alcohol, using maleic anhydride as catalyst, makees in conjunction with sodium carbonate
It is prepared furfuryl alcohol resin timber for stabilizer and ethanol and methanol as compounded organic solvent and optimizes liquid, there is preparation technology
Simply, raw material is easy to get, with low cost, stable performance is superior and the feature such as high-efficiency environment friendly.The formula of this optimization liquid is nontoxic, Halogen,
Good environmental protection, belongs to environment-friendly type Wooden modifying and processes optimization liquid, does not produces environment and pollute during producing and using.Logical
Cross the resistance leachability of the modified timber of this optimization liquid, dimensional stability, antiseptic property and mechanical performance to be all greatly improved.
Detailed description of the invention
In order to deepen the understanding of the present invention and understanding, following example are used for illustrating the present invention, but are not limited to this
The scope of invention.
