Abstract
The invention relates to a modification treatment method for woods. The modification treatment method comprises the following steps: a. carrying out oil heat treatment; b. after vegetable oil is naturally cooled to a room temperature, releasing the vegetable oil in a heat treatment tank and taking out sheet materials; c. pre-pressing; and d. carrying out surface oil removing treatment. According to the modification treatment method for the woods, the rotting-resisting and anti-mold properties, the size stability, the machinability and the interface bonding performance of the woods can be remarkably improved under the precondition that the mechanical properties of the woods are kept.
Description
Technical field
The invention belongs to the processing technique field of timber or similar material, be specifically related to the method for timber being carried out to modification.
Background technology
The artificial fast-growing woods such as poplar, China fir, masson pine becomes the main industrial cut stock seeds of China.But due to these wood grows rapidly, density is less, intensity is lower, not many defect restrictions such as corrosion resistant and reduce their application and use value.Heat_treated wood is a comparatively ripe modification technology in numerous Wooden modifying processing method, under it refers to condition timber being put into partially or completely starvation, with high temperature super heated steam, nitrogen, oil for heat transfer medium, timber is carried out to a kind of physical modification method of certain hour high-temperature heat treatment, be successfully applied to the fields such as floor, furniture, architectural decoration material.
Oil heat-treated wood surface and cell interior are all covered by grease and fill, and its oil content is high.Its too high oil content brings great inconvenience to later-stage secondary processing and use, if can on the basis not affecting oily heat treatment wood property, the oil of wood, bamboo culm inner " unnecessary " is therefrom removed, not only cost of material can be reduced, its serviceability can also be improved, will have important practical significance.
Summary of the invention
The object of this invention is to provide a kind of Wooden modifying processing method, with under the prerequisite keeping timber, mechanical property, significantly change its corrosion resistant fungicidal properties, dimensional stability, machinability, interface glue performance.By the timber after the method process and bamboo wood, mechanical property is substantially constant, but has good corrosion resistant fungicidal properties, and good stability of the dimension, machinability are good, bonding strength is high.
A kind of to Wooden modifying processing method, it comprises the steps: a, oily heat treatment: under the immersion of the sheet material of timber is had the liquid level of the heat treatment tank of vegetable oil, to heat treatment tank heating, make vegetable oil temperature between 180-190 DEG C, insulation 1-3h; B, after vegetable oil naturally cools to room temperature, in heat treatment tank vegetable oil release, take out sheet material; C, precompressed: sheet material pressure 2Mpa, temperature 120 DEG C of hot pressing on hot press, hot pressing time 10-20min; D, surperficial deoiling treatment: immersed by the sheet material after precompressed and be equipped with in the reactor of organic solvent, design temperature 60-90 DEG C, dip time 1-3h, released by the organic solvent in reactor, vacuumize 40-50min, lixiviate goes out the vegetable oil of sheet surface.
Described vegetable oil is a kind of in soybean oil, rapeseed oil, cottonseed oil, rice bran oil, corn oil, sunflower oil.
Described organic solvent is a kind of in ethanol, hexane, acetone, isopropyl alcohol.
The beneficial effect of this Wooden modifying processing method: method of the present invention, gives the characteristic of timber corrosion resistant, mildew-resistant, good stability of the dimension by oily heat treatment under can being retained the prerequisite of timber self-strength.Precompressed can make the oil in timber distribute at sheet material inner homogeneous, allows unnecessary oil spill go out.Lixiviate can to the further de-oiling of timber, especially can to sheet material outer surface and the inside de-oiling effect near outer surface better, to improve interface glue performance and the later stage Spraying technique of timber.
Detailed description of the invention
Below in conjunction with embodiment, the present invention is further described.
