Abstract
The invention discloses an antifouling wood softening agent capable of improving the handfeeling of woods. The softening agent is prepared by mixing traditional ammonia water and urea to prepare a basic softening solution and adding polyvinyl alcohol into the basic softening solution; if the softening agent permeates into woods, fibers can be tightly adhered, so that the loose structures of the woods can be improved, and furthermore the strength of softened wood fibers can be improved; in addition, the softening agent is used for improving the handfeeling of the fibers and improving the antifouling and waterproof performances together with raw materials such as water-soluble silicon oil and polyacrylamide, a dried and shaped wood workpiece is high in strength, good in toughness, compact in structure and smooth in surface, the antifouling wood softening agent is more efficient as comparison with the traditional treatment method, and the additional use values of the woods are increased.
Description
Technical field
The present invention relates to timber sofening treatment technical field, particularly relate to a kind of anti-soil and timber softening agent that can improve timber feel 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 anti-soil and timber softening agent that can improve timber feel and preparation method thereof.
The present invention is achieved by the following technical solutions:
Anti-soil and can improve the timber softening agent of timber feel, this softening agent is made up of the raw material of following weight portion: urea 1-1.5, neopelex 0.1-0.2, polyvinyl alcohol 1-2, polyacrylamide 0.4-0.5, concentration are 25-28% ammonia spirit 50-60, water-soluble silicon oil 1-2, deionized water 10-15.
Described a kind of anti-soil and the preparation method of the timber softening agent of timber feel can be improved, preparation process is as follows: first drop in deionized water by neopelex, urea, polyacrylamide, be stirred to after dissolving completely, mixed solution is heated to 65-80 DEG C, add polyvinyl alcohol, be stirred to after it dissolves completely and add other leftover materials, be uniformly mixed and obtain described softening agent.
Described a kind of anti-soil and the timber softening agent that can improve timber feel 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 70-80 DEG C, processing time is 40-50min, 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 hybridly prepared into basic bating liquor with traditional ammoniacal liquor and urea, and add polyvinyl alcohol wherein, it penetrates in timber and fibre compact can be adhered to, improve the structure that timber is loose, thus make the wood fibre intensity after softening obtain lifting, and and water-soluble silicon oil, the raw materials such as polyacrylamide improve the feel of fiber together, improve anti-soil water resistance, wood workpiece intensity after dryness finalization is high, good toughness, structure is compacted, surface is smooth, more efficient than traditional treatment method, improve the additional use value of timber.
Detailed description of the invention
This embodiment softening agent is made up of the raw material of following weight portion: urea 1, neopelex 0.1, polyvinyl alcohol 1, polyacrylamide 0.4, concentration are 25% ammonia spirit 50, water-soluble silicon oil 1, deionized water 10.
The preparation process of this softening agent is as follows: first drop in deionized water by neopelex, urea, polyacrylamide, be stirred to after dissolving completely, mixed solution is heated to 65 DEG C, add polyvinyl alcohol, be stirred to after it dissolves completely and add other leftover materials, be uniformly mixed and obtain described softening agent.
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 75 DEG C, processing time is 45min, processing pressure is 1MPa, 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 25.8%, density improves 8.5%, 24h water absorption rate reduces by 24.2%, plank after process than raw sheet length and thickness contraction rate all≤5.0%, show the workpiece size good stability after softening, its Surface feel is smooth, not easily adheres to dirt.
