Description
Technical field
The invention belongs to wood plastic product technical field.More particularly, to a kind of preparation method of UV printing wood plastic products.
Background technology
It by plant fiber powder (wood powder, stalk, forestry three remain thing etc.) and thermoplastic is main that wood plastic composite, which is,
Raw material, a kind of novel environment-friendly composite material manufactured by physics, chemistry and biotechnology grade high technical matters.Its zero first
Aldehyde, it is resistance to damage by worms, be corrosion-resistant, chemically-resistant reaction, water imbibition are small etc. at the same cause the advantages of having timber and plastics concurrently its transport service,
The fields such as interior decoration, construction industry, article of furniture industry, garden landscape are widely used.
Since wood plastic product is generally by made of extruder for shaping, wood plastic product rough surface, lacks
The graceful lines that timber has in itself, in order to meet consumers' aesthetic demand and needs, therefore generally to wood plastic product surface into
Row processing.The surface treatment method of wood plastic product is more, and some is artificial using cladding, thermal transfer, the method for plastic uptake, some carry out
The method brushed is painted, these methods production appearance is poor, and case hardness is low, service life is short, can not meet consumer's
Use demand.
CN201310307316.0 discloses one kind and sprays machine to wood plastic product progress surface treatment method using UV, it is led
The surface of wood plastic product handle and then carries out wood moulding system with the machine of spraying by the Eusol of 1% concentration of preparation
Product surface sprays, and use is red, blue, black, Huang Si kind UV inks, and computer control sprays machine and sprays various wood grains on wood plastic product surface
And pattern, but it is anticipated by Eusol, complex disposal process and not environmentally, and cost is higher.
The content of the invention
In order to solve the above technical problems, first purpose of the present invention is to provide a kind of preparation of UV printings wood plastic product
Method.
To reach above-mentioned purpose, the present invention uses following technical scheme：
A kind of preparation method of UV printings wood plastic product, includes the following steps：
1) surface of wood plastic product is first subjected to sanding polishing；Then the wood plastic product surface after polishing coats one layer of UV
Based white primer；
2) the UV based white primers on wood plastic product surface described in ultraviolet source irradiation carry out first time top layer curing, after curing again
Carry out sanding dedusting；Then printed using UV ink, must have figuratum wood plastic product；
3) the figuratum wood plastic product of tool carries out second of top layer curing described in ultraviolet source irradiation；Described after curing
Wood plastic product surface coats one layer of UV finishing coat；
4) wood plastic product for being coated with UV finishing coats carries out heating levelling using infrared light supply；By the wood plastic product after levelling
Third time top layer curing is carried out using ultraviolet source irradiation；UV printing wood plastic products are obtained after curing.
Preferably, the sanding polishing can not only enhance the flat smooth degree on the wood plastic product surface, Er Qieke
To remove the dust on wood plastic product surface and dirty.
Preferably, the UV based white primers dosage is 110-150g/m2；On the surface of wood plastic product, coating based white primer not only may be used
To strengthen the adhesive force of wood plastic product, but also the UV printing effects in wood plastic product later stage can be improved.
Preferably, the UV ink usages are 130-160g/m2。
Preferably, the UV finishing coats dosage is 110-130g/m2。
Preferably, in step 2), the wood plastic product printed is subjected to sanding dedusting, must have figuratum wood plastic product.
Preferably, the first top layer cured time is 5-10s, and second of top layer cured time is 3-5s,
The third time top layer cured time is 3-5 seconds.
Preferably, the temperature of the heating levelling is 30-80 DEG C, time 5-10min；Heating levelling can make UV finishing coats
It is more smooth, uniform on wood plastic product surface.
Preferably, the wavelength of ultraviolet source is 280-400nm, and energy is 800-1000mw/cm2。
Preferably, the wavelength of the infrared light supply is 850-940nm.
Preferably, the infrared light supply is infrared lamp；It is highly preferred that the power of the infrared lamp according to suitable temperature into
Row selection.
Preferably, the ultraviolet source is ultraviolet lamp, and the power of the ultraviolet lamp is 800-1500w.
Preferably, the temperature of the heating levelling is 45-60 DEG C, time 10-15min.
Preferably, in order to make the progress of wood plastic product preferably cure, it is respectively provided with the both sides of the wood plastic product ultraviolet
Lamp is used to irradiate.
Multiple top layer curing is the major way of UV coating photocurings, after being surface-treated to surface of wood-plastic composite material
UV coating is sprayed, by using ultraviolet light, UV coating instantaneous solidifications can be made, without drying time, greatly shorten application stream
Journey.Using infrared heating levelling, the volatilization of paint thinner and the chemical reaction of paint are mainly to speed up, shortens the marquis such as coating
The dry time.
Beneficial effects of the present invention are as follows：
Not only case hardness is high, wearability is strong for the UV printings wood plastic product that 1st, prepared by method using the present invention, do not fade,
The service life time is grown, and will not produce any smell for having harm to body, environmentally protective.
2nd, method using the present invention prepares UV printing wood plastic products, and process costs are low, efficient, simple and convenient.
