Description
Technical field
The present invention relates to the metope manufacture fields of building field, and in particular to a kind of thermal transfer side for building wall
Method.
Background technique
Building wall can use thermal transfer technology due to needing to print associated picture, and thermal transfer technology refers to high warm
Adhesive layer melting on the lower flower film of roller effect is viscoelastic state, and the pressure of hot-rolling is again by adhesive layer rapid link to material table to be transferred
Face, cool down rapidly thereafter flower film winding, is torn at separating layer, and PET film is by stripping, the finally protection on flower film, layer, oil
Layer of ink, adhesive layer are attached in material to be transferred.
Hot melt adhesive is a kind of adhesive of plasticity, and frequently as thermal transfer adhesive material, room temperature is in solid state, heating
After thawing can rapid link, but only use the adhesive layer of hot melt adhesive since hot melt adhesive melt viscosity is generally higher, to by viscous material
The wellability of material is poor, it usually needs pressurized adhesion, so as to improve adhesive strength；In addition, in the curing process using hot melt adhesive
Easily there is " anti-viscous " phenomenon, i.e., is easy to stick together with PET (" returning viscous ") after adhesive layer hot melt when environment temperature is higher, because
This limits its application range to a certain extent.
For building wall, exterior wall is often out-of-flatness, in the prior art, in order to improve the attachment of adhesive layer
Decorative cover after power and holding transfer is consistent, is using heat when using other materials such as aluminium sheet, glass etc. as thermal transfer carrier
Transfer glue closely pastes heat-transferring printing paper and aluminium sheet decorative cover, this just will appear the phenomenon that above-mentioned " anti-viscous "；Another way
It is to be covered outside the aluminium sheet of the complete heat-transferring printing paper of dry-laid with tubulose heat resistant plastice swollen bag, then keep heat-transferring printing paper abundant with the mode vacuumized
It is effectively tightly attached on aluminium sheet face, but for metope, area is too big, it is mobile inconvenient, so using in the curing process
It vacuumizes.
There is the method for solidifying using adhesive layer UV and replacing heat cure in the prior art, it is ineffective, the reason is that UV is cured
Though adhesive layer will not increase the phenomenon that generating " anti-viscous " because of environment temperature, radiation-curable to arrive after ultraviolet light passes through ink layer
The ultraviolet light of adhesive layer is less, causes curing time long, solidifies not comprehensive, adhesive force decline, and must add light in adhesive layer
Initiator can just cause the polymerizing curable of bonding agent.
Summary of the invention
To solve the above problems, the present invention provides a kind of heat-transferring method for building wall, mentioned for building wall
The adhesive force of high thermal transfer facing and metope, the decorative cover after keeping thermal transfer is consistent, prevents from instead gluing phenomenon, is not necessarily to photoinitiator
UV solidification can be realized.
The technical solution that the present invention solves is to provide a kind of heat-transferring method for building wall, comprising the following steps:
(1) by the solid containing polyvinylpyrrolidone cure to curing degree be 40% after, as adhesive layer prepare thermal transfer
Flower film；
(2) raw lacquer is coated on building wall to be transferred to building wall surfacing to be transferred；
(3) thermal transfer film is fitted on building wall to be transferred in 1-5 minutes, ultraviolet irradiation processing, solidifies the heat and turns
Printed film.
Preferably, the solid includes the following component of mass fraction: 20-40 parts of polyvinyl pyrrolidones, 40-
50 parts of UV-Curable Prepolymers, 5-10 parts of photoinitiators.
Preferably, which is characterized in that the thermal transfer film includes the PET film successively overlapped, separating layer, protective layer, oil
Layer of ink, laccol layer, adhesive layer.
Preferably, which is characterized in that the intensity of the ultraviolet irradiation is 10-50mJ/cm2 S.
Preferably, which is characterized in that the UV-Curable Prepolymer includes acrylated epoxy resins, unsaturated polyester (UP), gathers
One or more of urethane, polythiol light-cured resin, polyenoid light-cured resin.
Preferably, which is characterized in that the photoinitiator includes benzoin and its derivatives, acetophenone derivs, three virtues
One or more of base sulphur bell salt.
Preferably, which is characterized in that the ink of the ink layer includes pigment, absorbing wavelength is different outside from the pigment violet
Initiator.
Preferably, which is characterized in that the laccol layer includes the light-cured resin component of miscible 30% laccol.
Preferably, the pigment includes one or more of phthalocyanine blue, Lithol Red, benzidine yellow, carbon black.
In the present solution, pre-processing using raw lacquer to building wall, building wall is filled and led up using the fluid mobility of raw lacquer
At the out-of-flatness of face, meanwhile, raw lacquer has the title of " king of coating ", for exterior wall, inherently needs coating exterior wall paint to protect
Building is protected, laccol is main component, the long side chain neighbour benzene two of different saturation of the laccol with 15-17 carbon atom in raw lacquer
The mixture of phenol, with the unsaturated bond on active phenolic hydroxyl group, side chain；In the preparation for turning printed film, select successively to fold
PET film, separating layer, protective layer, ink layer, the laccol layer, adhesive layer of conjunction, wherein adhesive layer includes polyvinylpyrrolidone, is
A kind of non-ionic macromolecule compound, the general aspects with water-soluble high-molecular compound, colloid protective effect, film forming
Property, caking property, hygroscopicity, solubilising or cohesion, in the present solution, load of the UV-Curable Prepolymer as polyvinylpyrrolidone
Body, carrier of the light-cured resin as laccol, so that the physical aspect feature of laccol and polyvinylpyrrolidone more meets behaviour
Making reality, laccol and polyvinylpyrrolidone, there are stronger hydrogen bonds, so that before laccol and polyvinylpyrrolidone are formed
Film is driven, in addition free radical polymerization can occur under ultraviolet light irradiation for the unsaturated bond on laccol side chain, firstly, ultraviolet light irradiation
Under, laccol phenolic hydroxyl group splits into laccol Semiquinone Radicals, causes the growth of carbon-carbon double bond on side chain, and chain growth forms two-dimensional structure
Polymer, at the same time, unsaturated bond on side chain under the initiation of free radical can further occurrence polymerization, pass through containing poly-
The adhesive layer of vinyl pyrrolidone, the photopolymerization in the case where not having photoinitiator, forms half interpenetrating network structure
Polymer obtains the multi-layer ultrathin membrane with half interpenetrating network structure of stable structure, and metope and adhesive layer solidification are more secured,
It is not in " anti-viscous " phenomenon, in the prior art, it is necessary to light be added in adhesive layer and draw and due to being solidified with UV instead of heat cure
Hair agent can just make bonding one polymer crosslink solidification, in the present solution, can then be drawn due to the characteristic of laccol without photoinitiator
It plays laccol interlayer, laccol to polymerize with adhesive layer, for the decorative cover thicker for ink layer, curing time shortens and more thorough
Bottom improves adhesive force.
In the prior art, polymerize due to bonding agent in solidification, often because of the local stress that is generated in polymerization process and
Planar disfigurement caused by contraction, and in the present solution, the polyurushiol of adjacent interlayer is tied, half interpenetrating network structure is formed,
Two kinds of factor collective effects cause the space of multilayer film to be compressed, and film thickness is caused to decline, the film that the variation of structure also improves
Hardness, simultaneously because the high molecular skeletal support effect of PVPON, so that the adhesive layer after solidifying still has even curface,
Maintain the order of film.
More preferably condition may be selected in this programme, and the pigment in ink selects within the scope of ultraviolet radiation absorption wavelength zone
One or more of phthalocyanine blue, Lithol Red, benzidine yellow, carbon black are selected, ultraviolet light is not shielded, and the free radical in ink
The absorbing wavelength area of initiator is overlapped with the maximum of pigment through wavelength zone, then UV can penetrate ink layer, consolidate to adhesive layer
