Description
Technical field
The present invention relates to powder coating technology field, specifically a kind of tung oil embossment transfer printing wood grain coating and preparation method thereof
And application.
Background technology
Transfer printing wood grain is a kind of common coating metal surfaces technology, is to be turned the figure wood grain on printing plate by transfer materials
Print to process and process that stock gets on.At present, the transfer printing wood grain of metal material mainly has a two types, one kind be
The method that electrostatic powder Surface of profile is electrostatically sprayed, one layer of thermosetting organic polymer powder is coated, by hot setting, in type
Material surface, which is formed, has certain infiltrative coating；Another kind is transfer printing wood grain electrophoresis section bar, is that base material is passed through into anodic oxidation
Compact, miniature hole is formed, metal ion or organic dyestuff are deposited in oxidation hole by the method for electrolysis or organic coloring, then
Water-soluble varnish or colored paint are deposited on Surface of profile by electrophoresis, uniform, smooth, smooth paint film is formed, by metal ion
Or organic dyestuff is deposited in oxidation hole, and a kind of product is made.By the method for transfer by transfer printing wood grain to workpiece surface, a side
Coated in face of workpiece surface, thus workpiece surface not fugitive color, extend the service life of workpiece, while wood grain is true to nature,
Product gear is improved, adds the aesthetic of workpiece；On the other hand, workpiece is after powder spray, the heat conduction of metal surface
Coefficient reduces, and has the effect of heat-insulated energy-conservation.Transfer printing wood grain is widely portable to aluminum alloy doors and windows, antitheft door, fire resistant doorsets, steel
The resistant to elevated temperatures metal material such as wooden furniture, file cabinet, computer casing, household electrical appliance, metal ornament.
At present, the main component of transfer printing wood grain coating is polyurethane, isocyanuric acid three-glycidyl ester（TGIC）, barium sulfate
Precipitation, pigment and some auxiliary agents.However, existing transfer printing wood grain product does not possess three-dimensional feel, powder consumption based on plane
More, aluminium per ton is about 50kg.Therefore, the tung oil embossment transfer printing wood grain coating that a kind of powder consumption is low, possesses three-dimensional feel is researched and developed
And its preparation method and application be the art urgent problem to be solved.
The content of the invention
The purpose of the present invention is high aiming at the product powder consumption of current transfer printing wood grain coating preparation, does not possess three-dimensional hand
A kind of the problem of sense, there is provided tung oil embossment transfer printing wood grain coating and its preparation method and application.
A kind of tung oil embossment transfer printing wood grain coating of the present invention, the mass fraction of each component is in the coating：Pure polyester
50-65%, isocyanuric acid three-glycidyl ester 6-10%, wood powder 21-35%, pigment 0.5-1.0%, levelling agent 2.0-3.0%, add lustre to
Agent 2.0-3.0%, styrax 0.5-1.0%, wherein the mass fraction sum of each raw material is 100%.
The mass fraction of heretofore described each component is preferably：Pure polyester 58%, isocyanuric acid three-glycidyl ester 8%,
Wood powder 28%, pigment 0.8%, levelling agent 2.3%, optical brightener 2.2%, styrax 0.7%.
Heretofore described wood powder is by 120-130 DEG C of dry 2-3h, is obtained after 100-120 mesh sieves.
A kind of preparation method of tung oil embossment transfer printing wood grain coating of the present invention, comprises the following steps：
（1）Mixing：Pure polyester, isocyanuric acid three-glycidyl ester are weighed in proportion, wood powder, pigment, levelling agent, are added lustre to
Agent, styrax, it is placed in stirrer for mixing 5-10min；
（2）Extrusion：Material after above-mentioned be well mixed is placed in the extruder that temperature is 110-130 DEG C, material passes through
After being sufficiently mixed melting, by extrusion, tabletting, the thick thin slices of 1-2cm are cut into, and it is 1-2cm to crush to area2Irregular piece
Material；
（3）Milling：Above-mentioned thin slice is placed in flour mill and clayed into power, powder is crossed into 120-160 mesh sieves can obtain this
Invent the coating prepared.
A kind of application using tung oil embossment transfer printing wood grain coating in transfer printing wood grain section bar is prepared of the present invention, including with
Lower step：
（1）Pre-treatment：Workpiece surface is cleaned up and dried；
（2）Solidification：It is oven for curing at 200-240 DEG C by above-mentioned powdery paints using spray gun spraying in substrate surface
Workpiece is taken out after 10-15min；
（3）Transfer printing wood grain：Woodgrained paper is coated in workpiece surface, then puts elevated-temperature seal bag film, negative-pressure vacuum is carried out and takes out
Suction makes woodgrained paper tightly attach on the surface of the workpiece, then workpiece is sent into 170-200 DEG C of baking oven and toasts 6-12min, exits
Baking oven, directly remove woodgrained paper, you can obtain the section bar after transfer printing wood grain.
Wood powder in the present invention is ground into by timber polishing, generally refers to sawmill, Furniture Factory, density board factory, multilayer
Plate factory timber processes remaining leftover bits, can select pine, cypress, willow, camphorwood, maple, redwood, nanmu etc., have
Several effects below：（1）Due to wood powder not heat conduction thus have the function that heat-insulated；（2）Coated by pure polyester, consolidated by levelling
Crystal is formed in product surface after change, just because of the formation of the crystal, embossment figure is formd one with woodgrained paper
Fixed gap, thus the super good de- paper during de- paper, while effectively avoid damaging embossment figure during de- paper, reduce waste product
Rate, simultaneously because the crystal possesses special feel, thus the embossment wood grain transfer printing type material concave-convex surface prepared has cause, has day
The three-dimensional feel of right woodiness touch.
The present invention has following advantage：
（1）Due to the addition of wood powder in the coating of the present invention, therefore the heat transfer coefficient of workpiece surface reduces, effect of heat insulation
Good, spray area is wide, and powder utilization is high；
（2）The coating powder consumption of the present invention is low, and current coating aluminium powder consumption per ton is about 50kg, and coating of the present invention
Aluminium powder consumption per ton is about 30kg, reduces 40%；
（3）Surface of profile clean mark prepared by the present invention, surface crystal reflect different colors with the change of light
And gloss；Workpiece surface has superpower three-dimensional feel, uneven, is not likely to produce aestheticly tired；
（4）Not influenceed during transfer printing wood grain by woodgrained paper mimeograph, percent defective is low, super good de- paper, never hazes,
Ensure the fine definition of wood grain unity and coherence in writing.
