Description

A kind of mildew and insect proof artware timber sofening treatment liquid and preparation method thereof

Technical field

The present invention relates to chemical treatments technical field, particularly relate to a kind of mildew and insect proof artware timber sofening treatment liquid And preparation method thereof.

Background technology

In the course of processing of Wood craft, the timber as raw material is carried out softening is very important step.? Under usual conditions, timber is a kind of material lacking plasticity, by timber is carried out sofening treatment, it can be made to show temporarily Plasticity, now timber can be curved, compress, the plastic working such as embossment, then be dried under deformation, recover it Original rigidity and intensity, it is achieved the permanent plastic deformation of timber, the artware intensity making making is high, and morphological appearance is ornamental Can be good.Common softening method has decocting in water, high-temperature high-pressure steam to process and Chemical treatment.Process through these methods Wood dimensional stability is poor, and processing characteristics and serviceability also can be adversely affected.Patent CN201510993437 is with ice vinegar Acid, Polyethylene Glycol and anion surfactant are that main component prepares timber softening agent, make the timber after process have well Strength and stiffness, although this softening agent improves processing characteristics and the stable molding of timber after sofening treatment to a certain extent Property, but timber after softening processing is prone to craze and transfiguration, the most mould perishable defect is not significantly improved, it is therefore desirable to enter One step is perfect.

Summary of the invention

The object of the invention is contemplated to make up the defect of prior art, it is provided that a kind of mildew and insect proof artware timber softens Treatment fluid and preparation method thereof.

The present invention is achieved by the following technical solutions:

A kind of mildew and insect proof artware timber sofening treatment liquid, it is to be prepared by the raw material of following weight parts:

The hydrogen peroxide 2-4 of Polyethylene Glycol 5-10, glacial acetic acid 4-6, Alumen 0.5-1, mass fraction 20-30%, polyvinyl alcohol 1-2, Chinese mugwort Leaf 2-4, Cortex Meliae 2-4, Folium Zanthoxyli Bungeani 1-1.5, dodecylbenzene sodium sulfonate 0.3-0.5, tea saponin 0.1-0.15, carboxymethyl chitosan Sugar 0.1-0.15, tall oil 0.1-0.15, ethyl hydroxybenzoate 0.01-0.015, water 60-80.

The preparation method of a kind of mildew and insect proof artware timber sofening treatment liquid, comprises the following steps:

(1) weigh raw material by weight, first polyvinyl alcohol is added to the water 80-90 DEG C and stirs until being completely dissolved, be subsequently adding ten Dialkyl benzene sulfonic acids sodium and tea saponin 600-1000r/min stir 0.5-1h, are eventually adding hydrogen peroxide in 50-60 DEG C, 400- Stir process 2-4h under the conditions of 600r/min, is cooled to room temperature；

(2) Folium Artemisiae Argyi, Cortex Meliae, Folium Zanthoxyli Bungeani and ethyl hydroxybenzoate are added 80-90 DEG C of decoction 1-in the solution that step (1) obtains 2h, cooled and filtered removes filtering residue, adds glacial acetic acid and stirs, be eventually adding Alumen stirring at normal temperature 1-in the filtrate obtained 2h；

(3) remaining raw material is added stirring at normal temperature 1-2h in the solution that step (2) obtains, obtain mildew and insect proof artware timber soft Change treatment fluid.

The invention have the advantage that

The present invention utilizes hydrogen peroxide to make polyvinyl alcohol partial hydrolysis, reduces viscosity, improves dissolubility, has lumber fibre Good lubrication permeability and binding ability, also advantageously improve the toughness of lumber fibre；Add Alumen and introduce aluminium ion, pass through Metal ion and the combination of wood fibre, be conducive to improving rigidity and the intensity of timber, and the size simultaneously improving lumber fibre is steady Qualitative；By the composite synergistic effect of above-mentioned raw materials, then with glacial acetic acid, surfactant, Polyethylene Glycol conventional wood softening agent Composition and remaining raw material compound, the timber sofening treatment liquid softening good processability obtained, the intensity of timber, toughness height, It is difficult to bounce-back, does not affect that the finished size stability after subsequent treatment, and drying and moulding is high, be difficult to craze and transfiguration, mildew-resistant, anti- Worm is effective, and applied widely, energy-conserving and environment-protective.

Detailed description of the invention

A kind of mildew and insect proof artware timber sofening treatment liquid, is prepared from by the component raw material of following weight (kg):
