Abstract
The invention discloses a kind of chitosan hydroxyl apatite artware timber sofening treatment liquid, it is to be prepared by the raw material of following weight parts: dodecyldimethylammonium hydroxide inner salt 0.3 0.5, carbomer 0.1 0.15, Polyethylene Glycol 5 10, glacial acetic acid 46, Alumen 0.5 1, the hydrogen peroxide 24 of mass fraction 20 30%, polyvinyl alcohol 12, chitosan 0.1 0.15, hydroxyapatite 0.5 1, ethyl hydroxybenzoate 0.01 0.015, water 50 60.The timber sofening treatment liquid of the present invention softens good processability, the intensity of timber, toughness are high, be difficult to bounce-back, do not affect that the finished size stability after subsequent treatment, and drying and moulding is high, be difficult to craze and transfiguration, be not susceptible to mould corruption, and applied widely, energy-conserving and environment-protective.
Description
Technical field
The present invention relates to chemical treatments technical field, particularly relate to a kind of chitosan-hydroxy-apatite stone artwork 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 chitosan-hydroxyapatite technique
Product timber sofening treatment liquid and preparation method thereof.
The present invention is achieved by the following technical solutions:
A kind of chitosan-hydroxy-apatite stone artwork timber sofening treatment liquid, it is to be prepared by the raw material of following weight parts:
Dodecyldimethylammonium hydroxide inner salt 0.3-0.5, carbomer 0.1-0.15, Polyethylene Glycol 5-10, glacial acetic acid 4-6, Alumen
The hydrogen peroxide 2-4 of 0.5-1, mass fraction 20-30%, polyvinyl alcohol 1-2, chitosan 0.1-0.15, hydroxyapatite 0.5-1, Buddhist nun
Pool gold ethyl ester 0.01-0.015, water 50-60.
The preparation method of a kind of chitosan-hydroxy-apatite stone artwork 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 dimethyl glycine betaine 600-1000r/min stirs 0.5-1h, is eventually adding hydrogen peroxide in 50-60 DEG C, 400-600r/
Stir process 2-4h under the conditions of min, is cooled to room temperature；
(2) carbomer and ethyl hydroxybenzoate are added 60-80 DEG C of stirring 0.5-1h in the solution that step (1) obtains, add after cooling
Enter glacial acetic acid to stir, be subsequently adding chitosan and stir until being completely dissolved, be eventually adding hydroxyapatite and Alumen room temperature
Stirring 1-2h；
(3) remaining raw material is added stirring at normal temperature 1-2h in the solution that step (2) obtains, obtain chitosan-hydroxy-apatite lapicide
Skill product timber sofening treatment liquid.
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；Chitosan, hydroxyapatite have good bonding, filling capacity to lumber fibre, are conducive to improving wooden fullness
And intensity, improve the stability of timber；By the composite synergistic effect of above-mentioned raw materials, then with glacial acetic acid, surfactant, poly-second
Glycol conventional wood emollient ingredients and remaining raw material compound, and the timber sofening treatment liquid obtained softens good processability,
The intensity of timber, toughness are high, be difficult to bounce-back, do not affect the finished size stability after subsequent treatment, and drying and moulding high, no
Deformation easy to crack, it is not susceptible to mould corruption, and applied widely, energy-conserving and environment-protective.
Detailed description of the invention
A kind of chitosan-hydroxy-apatite stone artwork timber sofening treatment liquid, by the component raw material system of following weight (kg)
For forming:
Dodecyldimethylammonium hydroxide inner salt 0.3, carbomer 0.1, Polyethylene Glycol 5, glacial acetic acid 4, Alumen 0.5, mass fraction 20%
Hydrogen peroxide 2, polyvinyl alcohol 1, chitosan 0.1, hydroxyapatite 0.5, ethyl hydroxybenzoate 0.01, water 50.
The preparation method of a kind of chitosan-hydroxy-apatite stone artwork timber sofening treatment liquid, comprises the following steps:
