Description
Technical field
The invention belongs to woodwork furniture processing technology fields, and in particular to a kind of Surface finishing processes of elm furniture.
Background technology
Elm is Ulmaceae, Elm, main product temperate zone, deciduous tree, and tree is tall and big, throughout northern various regions, especially Yellow River basin, with
Locate visible.Elm wood is tough and tensile, and texture is sensible clear, and hardness and moderate strength, general openwork carving embossment adapt to, planing surface light
Sliding, chord plane decorative pattern is beautiful, there is the decorative pattern of " Door frame ".
For use such as furniture, finishings, elm drying, shaping, carving coat with lacquer paint, can make exquisite carved lacquerware handicraft article.With
The old elm of Russia (i.e. purple elm) is the most classical, and it is few to have the advantages that clean mark, tree scab greatly, is the rare material for making furniture
Matter, 1500 yuan or so of every cube of prices of raw materials of elm.The grain of wood leads to directly, and decorative pattern is clear, and elasticity of wood is good, moisture-proof, corrosion resistant.
Air-dry density：0.68g/cm3, wooden hardness is moderate, easily dries, and is unlikely to deform not easy to crack, is to make preferred rare of furniture
Timber.Decorative pattern is beautiful, in beautiful color generous.Suitable for noble furniture, cabinet, carved lacquerware handicraft article etc..The shallow white slightly biased Huang of its wood color,
Wood grain is unintelligible, and heart sapwood or morning and evening wood color difference are excessive, and surface colourity is uneven, and modern is more biased towards the hobby of furniture wood color
In the log wood color naturally simple, color uniformity is strong, wood grain is more visible.
The content of the invention
The purpose of the present invention is being directed to the problem of existing, a kind of Surface finishing processes of elm furniture, elm wood are provided
Material is covered with paint, lacquer, colour wash, etc. again after treatment, and coverage significantly improves, and evenness degree is excellent.
The present invention is achieved by the following technical solutions：
A kind of Surface finishing processes of elm furniture, comprise the following steps：
（1）The elm timber of 3-4 is selected, is modified, used using the method for pulsed impregnating by pressure at timber both ends
Main modifying agent is made according to mass percent meter of following component：Polyvinyl alcohol accounts for 1.3-1.5%, succinic acid dialkyl ester sulfonic acid
Ammonia accounts for 1.0-1.2%, casein accounts for 0.8-0.9%, sodium sulphate accounts for 0.7-0.8%, petroleum sodium sulfonate accounts for 0.5-0.7%, sulfomethylated lignin
Acid accounts for 0.4-0.6%, remaining as water, and main modifying agent action time is 30-40 minutes, and pressure 0.5-0.6MPa, auxiliary modifying agent is made
It is 15-20 minutes with the time, pressure 0.3-0.4MPa；
（2）Concentration is that the hydrogen peroxide of 0.13-0.15% wipes the wood surface after modification, then cleans 2-3 with clear water
Time, water content is dried at 50-60 DEG C in 3-5% scopes, using first of seal coat of wool brush, at 38-40 DEG C after brushing
Warm light light irradiation under dry 4-6 it is small when, then polished with 600 mesh sand paper along grain direction, then carry out second closing bottom
The brushing of paint, when drying 5-7 is small under 38-40 DEG C of warm light light irradiation after brushing；
（3）After priming paint is covered with paint, lacquer, colour wash, etc., the brushing of varnish is carried out, with polyurethane and acrylic acid according to 1:It is prepared by the mixed proportion of 4-5
Synthetic for film forming matter dumb light water paint as clear prime 2 times, when dry 5-6 is small after brushing, then brush one layer
Clear finish, the clear finish used are the emulsion coatings that polyurethanes lotion is film forming matter.
As further improvement of these options, step（1）The preparation method of the main modifying agent is：By polyethylene
Alcohol is added to the water, and is heated to 70-80 DEG C, when stirring 1-2 is small under 300-400 revs/min, then adds in succinic acid dialkyl
Ester sulfonic acid ammonia, casein and petroleum sodium sulfonate, continue to be dispersed with stirring 2-3 it is small when, be finally cooled to 30-35 DEG C, add in remaining former
When material mixing 1-2 is small.
As further improvement of these options, step（1）The auxiliary modifying agent according to mass percent meter by with
Lower ingredient is made：Cationic-type polyacrylamide accounts for 0.4-0.6%, epoxidized polyamide resin accounts for 0.8-1.0%, polyethyleneimine
Account for 1.3-1.5%, Lauxite accounts for 1.5-1.7%, remaining as water.
As further improvement of these options, step（3）The polyurethanes lotion is film forming matter
Mass concentration is 45-48%, and titanium dioxide addition mass percent is 12.5-14.0%.
As further improvement of these options, first of primer coating film amount be 90-100 grams/m, second
Road primer coating film amount is 60-70 grams/m, and clear primer coating film amount is 110-120 grams/m, and clear finish film amount is
120-130 grams/m.
The present invention has the following advantages compared with prior art：In order to solve the effect of existing elm furniture surface presentation not certainly
The problem of right, the present invention provides a kind of Surface finishing processes of elm furniture, carry out pulsed pressurization to elm timber first
The method of dipping is modified, then carries out paint film, reduces the internal stress and brittleness of paint film, improves the richness of paint film and resistance to
Long property, film mode had both remained the feature of acrylic acid aqueous paint strong adhesive force, and had also improved the wearability of paint film and anti-chemistry
Property, by being surface-treated, covering with paint, lacquer, colour wash, etc. the methods of embodies the naturally beautiful texture of elm material furniture, can not only play
Elm appearance itself and the effect of material are protected, the decorative appearance and physicochemical property of timber can be more improved, expand its application range,
Extend the service life of elm material furniture in itself.
