Description
Technical field
The present invention relates to moulding article and manufacture method thereof that a kind of surface has the decorative mark material, particularly relate to the moulding article and the manufacture method thereof of a kind of surface band stereoscopic vision image.
Background technology
In recent years, the difference of technology and properties of product is more and more littler, and outside cost performance of product, the user begins to give more concern to the style and the outward appearance of product.The consumer of today is considered as showing the fashionable life instrument of individual character and grade to the goods that they use, and selects suitable product according to outward appearance, brand and functional three aspects.The outward appearance of product is being brought into play important effect, must have the aesthetic feeling that attracts consumer alert and purchase.
Chromatic colour and pleasing even glittering decoration be added in the product go, with attracting sight and keep lasting and pay close attention to, decorative mark material a kind of decoration that comes to this.It is prior art that the decorative mark material is incorporated in the moulding article as characteristic, is called in-mold decoration method or in-mold label method.
It is stereoscopic vision image that above-mentioned decorative mark material has ornamental most, but will form real stereoscopic vision image grating lens must be arranged.It is so abundant that the material of energy moulding grating lens is nothing like injected plastics material, have only limited several transparent materials such as unformed PETG (APET), polymethyl methacrylate (PMMA), Merlon (PC), transparent random polypropylene (PP), transparent polystyrene (PS), transparent polyvinyl chloride (PVC) and cellulose acetate etc., what wherein be fit to large-scale production has only APET, PP and PVC again.Consider to have only APET and PP to be fit to use again from the food hygiene aspect.Grating lens with these material manufacturings carries out the in-mold decoration molding as decorative layer, has the problem of interface adhesive fastness.The conventional method that addresses this problem is to utilize the similar compatibility principle, be that moulding material is similar to the interior decorative coat molecular structure, but very big difficulty is arranged in practical operation, do not meet the requirement of moulding article diversity yet, when for example requiring injected plastics material to be PS, no matter be PET or PP, not compatible with PS.If adopt special compatilizer, there is the problem of the aspect such as smell, food hygiene of compatilizer again.If there is the coating difficulty in the employing PUR and makes the problem of aspects such as grating sheet distortion, and its goods are not suitable for contacting boiling water, because general thermosol fusion temperature is low, and the possibility that the contact boiling water has fusing to peel away.
Summary of the invention
Technical problem to be solved by this invention provides moulding article and the manufacture method thereof that a kind of surface has the decorative mark material, and this moulding article has kind variation and safety non-toxic and the advantage that can use under higher temperature.
The technical scheme that technical solution problem of the present invention is adopted is: the surface has the moulding article of decorative mark material, comprises decorative mark material layer and molding layer, between decorative mark material layer and molding layer the microcapsules adhesive is arranged.
Above-mentioned surface has the manufacture method of the moulding article of decorative mark material, may further comprise the steps: 1) will apply on the decorative mark material layer or printing microcapsules adhesive; 2) put into the die for molding moulding article.
The invention has the beneficial effects as follows: owing between decorative mark material layer and molding layer, the microcapsules adhesive is arranged, can effectively solve the interface adhesion problem between decorative mark material and inconsistent plastic material in the in-mold decoration moulding process, make the plastic material kind variation that is fit to in-mold decoration forming; The microcapsules adhesive is coated on the mark material decorative layer, so the decorative mark material adapts to telesecurity transportation and long-time the preservation, and in-die decoration production can be produced in the strange land; And this blanket clip does not contact with the external world in the middle of decorative layer and moulding plastics, does not therefore have the problem of food security aspect, i.e. safety non-toxic; Under the HTHP when molded, curing agent capsules break in the microcapsules adhesive, the resin generation curing cross-linking reaction that contains active group in instantaneous and the adhesive, or the instantaneous generation curing cross-linked of the adhesive capsules break of band active group in the vector resin or latency active group, thereby when in high temperature, using, adhesive can not melt again, thereby decorative layer is stripped down.
The specific embodiment
The manufacture method of moulding article of the present invention may further comprise the steps:
1) printed patterns on the decorative mark material; Or it is compound with base material behind printed patterns on the decorative mark material; Or it is compound with the decorative mark material behind printed patterns on the base material;
2) on decorative mark material that prints or composite decoration mark material, apply or printing microcapsules adhesive;
3) stamping-out becomes suitable shape; Or stamping-out becomes after the suitable shape hollow out again, engraves pattern or literal;
4) put into mould, adopt injection moulding, blowing, lamination or thermoforming molding goods;
5) after the hardening by cooling typing, from mould, take out the moulding article of band decorative mark material.
When above-mentioned decorative mark material is the decorative layer of band stereoscopic vision image, must adopt grating sheet, grating sheet comprises the array of a similar face curvature, and this array is formed on the front surface of sheet material, the rear surface generally is the plane, and pattern is printed on the tool back plane of grating sheet.
Be high temperature resistant, high pressure and the hot melting plastic fluid scouring performance that improves image, can compound one deck base material.Base material can be leather, rubber, textile, metal forming, plastic foil, paper, metallic plate, plank, fiberboard, rubber slab or glass etc.Wherein, paper can be to fill kaolinic heat-resisting paper; Plastic foil can be polyethylene, PP, PET, PC diaphragm etc.If when the base material that uses was metal forming or glass, moulding article had good barrier properties for gases, if when base material is fiber cloth, nonwoven or leather etc., the feel of goods can be very good.
If what moulding article used is thermosetting resin, just must use the heat curing-type binding agent.General heat curing-type binding agent is low-molecular-weight resin, must be dissolved in and adopt the mode that applies or print to use in the suitable solvent, but after solvent is removed, the surface also has certain viscosity, can not drop into next procedure, must heat and make it reaction and reach the B stage, that is: resin surface is tack-free, but stage that can also partial melting.If but controlled badly, heated baking would be excessive, and interfacial adhesion is descended; Underheat just might be trickled in moulding process, quality problems occur.And reach the B stage, resin must be heated to than continuing for some time after the higher temperature again, and this may make thermoplastic grating sheet distortion or optical property descend.To above-mentioned trickling problem, can use quick-setting resin to solve, but can make the storage period of grating sheet become very short like this, require harsh to production, storage condition.
Result of the above problems is to adopt microcapsules interface bonding technology: the microencapsulation of binding agent.Microencapsulation has dual mode, the one, be dispersed in the matrix resin of binding agent after the curing agent in bi-component or the multicomponent binding agent got up by film wrapped with trickle oil droplet shape, another kind is to be dispersed in the vector resin after the one component binders of band active group or latency active group is got up by film wrapped with trickle oil droplet shape.High temperature in the moulding process makes the resin fusing, high pressure makes capsules break discharge curing agent or one component binders, thereby in instantaneous solidification, fully satisfies the interface requirement of bonding fast, molding adds the trickling problem that glue can not appear again in man-hour simultaneously, the storage life problem of grating sheet also can not occur.This method equally also is suitable for the interface bonding of thermoplastic.
The microencapsulation adhesive is under heating or pressurized, and capsule destroys, curing agent that discharges and the polymer reaction of being with active group, or the instantaneous generation curing cross-linked of the adhesive capsules break of band active group in the vector resin or latency active group.Therefore, the destruction complexity of capsule becomes an active and stable key factor of microcapsules adhesive.When a little less than the capsule film, destructible in preparation constituent or transportation; When film is tough, need to strengthen operating temperature and pressure.The condition of work of the film of the microcapsules adhesive among the present invention is: temperature 120-300 ℃, pressure 7-170kg/cm
2Active group in the polymer of above-mentioned band active group comprises: epoxy radicals, NCO, carboxyl, hydroxyl, silicon hydroxyl, amido, acid anhydrides (as: maleic anhydride), unsaturated bond (as: two key) etc., the polymer of band active group comprises: resins such as epoxy resin, polyurethane, phenolic resins, unsaturated polyester (UP), polyacrylate, cyanoacrylate, maleimide, the polymer of all band active groups all can be used for the present invention.
The microcapsules adhesive is given an example: solution of acid chloride is poured in the container, dripped amine substance then, the oil droplets of formation coats with polyamide and forms capsule.For example drip 6% amine aqueous solution 3% in the sebacoyl chloride trichloro-ethylene solution of (percentage by weight, down with) and 3% the sebacoyl chloride xylene solution, form the amine capsule of polyamide parcel.The missionary society of the density of dimethylbenzene and trichloro-ethylene rests on their boundary layer capsule.
After being coated in the microcapsules adhesive on the mark material decorative layer, treating that solvent evaporates finishes carries out in-moldedly again, and this blanket clip does not contact with the external world in the middle of decorative layer and moulding plastics, so does not have the problem of food security aspect, i.e. safety non-toxic; Under the HTHP when molded, the resin generation curing cross-linking reaction that contains active group in the curing agent capsules break in the microcapsules adhesive, instantaneous and adhesive, thereby when high temperature for example uses in boiling water, adhesive can not melt again, thereby decorative layer is stripped down.
The present invention can adopt injection moulding, blowing, lamination or thermoforming process moulding moulding article.
The mark material processing method of blow-molded article during to the processing requirements of decorative mark material and injection mo(u)lding is basic identical, uniquely with injection moulding different be, because the difference on the mould structure, the sheet material of band stereoscopic vision image can only can not enclose around one on some surfaces of product.Because the pressure ratio injection moulding of blowing is much lower, therefore the interface adhesive fastness must be noted more, can adopt in decorative mark material material to add lower slightly the copolymerization material of fusing point, as when extruding random copolymerization PP grating sheet, add metallocene PP, PE, POE and/or POP etc.
For avoiding the undue distortion of raster image, the profile of goods is suitable mild, does not preferably have vertical cliff, and image should not be printed on the position of big stretcher strain.
Laminated product is to make supporting material with paper or cloth, soaks (or being coated with) with different resin adhesives, and drying is made the impregnation material, presses the size of laminated product then, and the impregnation material is carried out cutting, again the layer structure material that forms through hot pressing (or rolling).Laminated product has laminate, laminated tube, laminated rod and other special section bar etc.Ground commonly used has natural organic fiber, wood fibre or paper (as impregnation of fibers paper), cotton and inorfil such as glass fabric.Different grounds have different characteristics, and wood fibre paper saturating machine is good, is applicable to pressboard, pipe, rod; Cotton layer stampings bonding strength height, the wear-resisting machining that is easy to, glass colth laminate high temperature resistant, mechanical performance and chemical stability are good.In addition, also have laminated products such as plank, metal forming plate.Adhesive commonly used has phenolic resins, epoxy phenolics etc.Select for use different supporting materials and adhesive just can make the laminated product of different temperature classification and performance.For making the laminated product any surface finish attractive in appearance, general method is in 2～4 the higher surface layer of resinous amount impregnation materials of two sides, highest and lowest placement, perhaps to add calico etc. when stacking.
