Abstract
The invention discloses a wood softening agent containing lac. The softening agent uses such materials as ammonia water, urea and sodium borohydride for mixing to prepare basic softening liquid; lac pieces are added in the basic softening liquid, are dissolved to permeate into wood fibers under the effects of temperature and pressure, and are attached on the fibers to improve the thermoplasticity and the thermosetting property of the wood fibers so as to achieve the effect of tightening the fiber structure; and a smooth waterproof protection film can be formed to improve the wood durability; shaped wood workpieces are high in strength, firm and durable in plasticity, compact in structure and waterproof; and compared with a traditional treatment method, the efficiency is higher, and the additional use value of woods is improved.
Description
Technical field
The present invention relates to timber sofening treatment technical field, particularly relate to a kind of timber softening agent containing shellac and preparation method thereof.
Background technology
Timber is a kind of material lacking plasticity, and timber often needs when being processed as product first to carry out a series of sofening treatment, improves its plasticity, so as with the machine-shaping in later stage.The sofening treatment method of usual employing is poach, sprays the physical methods such as steaming or carry out sofening treatment by the chemical liquids such as liquefied ammonia, liquid caustic soda, the problem that the lumber fibre ubiquity intensity crossed of traditional processing method place reduces, have impact on the serviceability of product after plasticizing aftershaping greatly.
Summary of the invention
The object of the invention is exactly the defect in order to make up prior art, provides a kind of timber softening agent containing shellac and preparation method thereof.
The present invention is achieved by the following technical solutions:
Containing a timber softening agent for shellac, this softening agent is made up of the raw material of following weight portion: sodium borohydride 0.01-0.02, concentration are 25-28% ammonia spirit 50-60, urea 0.4-0.5, neopelex 0.1-0.2, shellac 2-3, glycerine 6-8.
The preparation method of described a kind of timber softening agent containing shellac, preparation process is as follows: first drop in ammonia spirit by shellac, is stirred to after it dissolves completely, then adds other leftover materials, namely obtain described softening agent after continuing to be uniformly mixed 40-50min.
Described a kind of timber softening agent containing shellac carries out sofening treatment method to timber, processing method is as follows: workpiece timber being processed into required specification, workpiece is immersed in softening agent completely and carries out airtight impregnating by pressure, treatment temperature is 50-60 DEG C, processing time is 2-3h, processing pressure is 0.5-1MPa, and process terminates rear taking-up workpiece, fully dryness finalization after cleaning.
The softening agent of preparation of the present invention is with ammoniacal liquor and urea, the mixing of materials such as sodium borohydride are mixed with basic bating liquor, and add shellac wherein, it penetrates in lumber fibre after dissolving under the effect of temperature and pressure, be attached to the thermoplasticity and thermosetting that fiber improve wood fibre, reach the effect of the fibre structure that compacts, and smooth water-fast diaphragm can be formed, improve the durability of timber, wood workpiece intensity after sizing is high, plasticity strong, durable, structure is compacted waterproof, more efficient than traditional treatment method, improve the additional use value of timber.
Detailed description of the invention
The softening agent of this embodiment is made up of the raw material of following weight portion: sodium borohydride 0.01, concentration are 25% ammonia spirit 50, urea 0.4, neopelex 0.1, shellac 2, glycerine 6.
Its preparation process is as follows: first drop in ammonia spirit by shellac, is stirred to after it dissolves completely, then adds other leftover materials, namely obtain described softening agent after continuing to be uniformly mixed 40min.
It is as follows to the processing method of timber: the Chinese fir board of to be 4% specification by moisture content be 200mm × 200mm × 5mm immerses in softening agent completely carries out airtight impregnating by pressure, treatment temperature is 50 DEG C, processing time is 2h, processing pressure is 0.8MPa, process terminates rear taking-up workpiece, fully dryness finalization after cleaning.
The performance test results of the workpiece after dryness finalization shows that the more undressed plain plate intensity of the plank after sofening treatment improves 45%, density improves 12.3%, 24h water absorption rate reduces by 42.4%, plank after process than raw sheet length and thickness contraction rate all≤5.0%, show softening after workpiece size good stability.
