Abstract
The present invention belongs to a protective technology for wood material, and is characterized by that after the wood material is undergone the processes of hydrolytic degreasing, vacuum dewatering and drying, the wood material is soaked in the modifying solution prepared by compounding halogen dihydric alcohol, maleic anhydride, phthalic anhydride and phenylethylene, then heated and pressurized to make wood fibre retain original form and have protective film formed, and make said wood material possess the water-proof, preserving and moth-proofing properties, and attain the goal of implementing non-deforming permanently. The treated wood material can be extensively used in humid environment.
Description
The invention belongs to the guard technology of timber, for a kind ofly preventing wood corrosion, crackle, damage by worms, absorb water, thereby change the method for wood property.
At present the method for Wooden modifying has two kinds of pressurization injection method and deep layer injection methods, its objective is make timber can be anticorrosive, damage by worms etc., impregnating agent generally is certain liquid, liquid contains the salt of various solubilities, these salts have certain toxic effect usually, timber for most seeds is inapplicable, and use face is narrower.
Task of the present invention is: overcome the deficiencies in the prior art, propose a kind of improvement character method of applicable various timber, make it waterproof, anticorrosion, increase the service life.
Task of the present invention realizes as follows: the degreasing that is hydrolyzed in the retort of at first timber being packed into, then timber is carried out vacuum dehydration, and after the dehydration timber is put into hothouse and carry out drying, make it water content and reach below 12%; The inherent timber of retort is prepared modifier liquid earlier before packing into, its method is: by weight percentage: the dihydroxylic alcohols 15-20% of halogen, maleic anhydride 15-20%, phthalic anhydride 10-20%, styrene 0-60%, mix and carry out the peroxide drying then, the curing drier that adds can be a benzoyl, cyclohexanone or first be ketone, wherein the ratio of drier and modifier liquid is 3-5: 100, reaction time is 30 minutes, timber can be added retort then, retort is heated to 50 ℃, and pressurization makes a jar internal pressure reach 1-2MPa, time is 1-3 hour, drying integer then handles, time is 24-30 hour, and temperature is 60-80 ℃.Slurries are shunted in current divider afterwards, and temperature is 90 ℃, and the time is 2 hours.
Modified solution avirulence of the present invention can the toxigenicity material, and the raw material source is wide, and cost is low and treatable timber variety is extensively unrestricted; The lumber fibre that adopts method of the present invention to handle can be kept intact, and all fibres all forms diaphragm, because the used resin calcium of modifier is natural resin, is difficult for oxidation, anti-aging; Turpentine oil is the rosin body, can make the soft easily processing of timber like this, and to do the resin water resistance of raw material good so the dihydroxylic alcohols of halogen, maleic anhydride, phthalic anhydride, styrene etc. all are oil; There is rosin calcium to do again and mixes the body complementation, so just formed excellent waterproof, anti-ly rot, anti-ly damaged by worms, anti crack performance, realize the never purpose of distortion, greatly prolonged the service life of timber.
A most preferred embodiment of the present invention, a, with the timber degreasing that is hydrolyzed in the retort of packing into; B, timber is carried out vacuum dehydration; C, drying reach below 12% the water content of timber; D, preparation modifier: 15 kilograms of the dihydroxylic alcohols of halogen, 15 kilograms of maleic anhydrides, 10 kilograms of phthalic anhydrides, styrene mix for 60 kilograms, carry out the peroxide dry solidification then, add the curing drier and select 3 kilograms of benzoyls for use, the reaction time is 30 minutes, then timber is added retort, retort is heated to 60 ℃, and pressurization makes a jar internal pressure reach 1-2MPa, and the time is 1-3 hour, dries integer then and handles, time is 24-30 hour, and temperature is 60-80 ℃.Slurries are shunted in current divider afterwards, and temperature is 90 ℃, can finish in 2 hours.
Second kind of embodiment of the present invention, a, with the timber degreasing that is hydrolyzed in the retort of packing into; B, timber is carried out vacuum dehydration; C, drying reach below 12% the water content of timber; D, preparation modifier: 20 kilograms of the dihydroxylic alcohols of halogen, 20 kilograms of maleic anhydrides, 20 kilograms of phthalic anhydrides, styrene mix for 40 kilograms, carry out peroxide then and solidify drier dry the adding, drier is selected 5 kilograms of cyclohexanones for use, reaction time is 24-30 hour, then timber is added retort, retort is heated to 60 ℃, and pressurization makes a jar internal pressure reach 1-2MPa, time is 3 hours, integer is handled then, slurries are shunted in current divider afterwards, and temperature is 90 ℃, and the time is 2 hours.
Claims (1)
1, a kind of substituting and setting method of timber, with the timber degreasing that is hydrolyzed, vacuum dehydration, dry, operations such as modification, it is characterized in that: each proportioning components of modified process solutions employed is: the dihydroxylic alcohols 15-20% of halogen, maleic anhydride 15-20%, phthalic anhydride 10-20%, styrene 40-60%, it is mixed, add drier peroxide drying then, wherein the ratio of drier and modifier liquid is 3: 100, the dry solidification time is 30 minutes, with vacuum dehydration, dried timber adds retort, retort is heated to 50 ℃, and pressurization makes a jar internal pressure reach 1-2MPa, time is 3 hours, carries out integer then and handles, and slurries are shunted in current divider afterwards, temperature is 90 ℃, and the time is 2 hours.
