Description
The manufacture method of modeling stock product with wooden-imitating
Technical field
The present invention relates to the manufacture method of plastic cement products, more particularly to a kind of method that Mu Pattern are made on plastic cement products.Background technology
Timber is widely used in the every field of social life and production, due to a large amount of felling of trees, causes the destruction and soil erosion of environment.Simultaneously timber use there is also it is certain the drawbacks of, the price of such as timber is relatively expensive, in addition, timber needs substantial amounts of labour in process, process is more complicated：Timber must first dehumidify before workshop converted products is sent to, and then be selected, and conduct oneself well timber is endless（Erodable section）Cut away, reduce utilization rate.Timber enter workshop after, by carpenter using simple machine tool by timber piecemeal fashion into final products, after the shape of product is formed, Wood products need the paint and polishing by several wheels, to create preferable surface smoothness.Therefore, according to the complexity of product, production process will take hours or even can just be done for several days.
The above-mentioned cost and the defect of process existed due to timber, so people make Mu Pattern in plastic surface carrys out simulated logs, is made the plastic cement products with wooden-imitating.The plastic cement products Mu Pattern processing methods generally used at present are generally divided into two groups.First prescription method obtains Mu Pattern decorative effects using printing, is generally used for the decoration of plane or two-dimensional products.Two-dimensional products include floor and furniture-plates etc..Second prescription method can not only decorate two-dimensional products and can decorate the surface of three-dimensional objects, therefore so that the prescription method is adapted to three-dimensional and made with Irregular Boundary Surface part Mu Pattern.Second prescription method mainly includes water transfer and decoration technique inside mold.
Water transfer technique technological process is as follows：
1st, material pre-treatment（Deoil, dust）；
2nd, upper fixture;
3rd, jet background（Paint）Or the processing of interface paint；
4th, baking vanish or certainly dry；
5th, transfer（Manually or automatically）：The corresponding pressure of picture and text on intermediate carrier film is transferred to the printing process on stock, referred to as transferred.Water transfer technique is a kind of printing process that the transfer paper with multicolour pattern/plastic foil is carried out to macromolecule hydrolysis using hydraulic pressure.The film that water transfer is handled with special chemical; after stamping required Se Cai Pattern roads; it is flat to send in the surface of water; utilize the effect of hydraulic pressure; Se Cai Pattern roads pattern is equably needed on product surface, makes coating film automatic dissolving in water, after cleaned and drying; the transparent protective coating of last layer again, at this moment product showed a kind of completely different visual effect；
6th, washing process（Wash away residual film）；
7th, dry；
8th, film is mended（Repairing）；
9th, spray paint（Protective paint）；
10th, baking vanish（Drying）.
It is a kind of ripe technology that Mu Pattern are made on plastic cement products using water transfer technique, and various Mu Pattern patterns may be selected.The technology can decorate the three-dimensional or irregular product of curved surface.But there is following defect in this method：1) deteriorate in last entrance Mu Pattern deformations or printing quality, particularly in the place for having depth.2) complex procedures, labor intensity is high.Main labor intensity is to transfer and mend membrane process.It is a necessary program to mend film, because the bubble produced by dipping process can make product produce flaw, it is necessary to eliminated by mending film.3) because diluent used and chemical article can be polluted to environment, so being unfavorable for environmental protection.
Decoration technique inside mold is put into the die cavity of the mould processed by film decorated molded and by cutting, the technology being then molded again.Decoration technique inside mold can be with the selection image of diversification, and product quality is stable.But in-mold decoration is costly, because the technology needs one
The extra film of layer and needs progress printing treatment, shaping on film（High-pressure molding, thermoforming, metal matched-mold forming）Cut, be then molded.In addition, Injection Mold Design, film forming and the technical requirements of cutting are higher, so that only a small number of manufacturers with professional ability could use this technology.
The content of the invention
It is an object of the invention to provide a kind of manufacture craft it is simple, with low cost, the manufacture methods of the plastic cement products with wooden-imitating of depth and timber sense of touch are managed with Zhen Shi Pattern.
To achieve these goals, present invention employs following technical scheme：A kind of manufacture method of the plastic cement products with wooden-imitating, comprises the following steps：

(4) film film is attached on die surface, and exposed with light-illuminating；
(5) film film is removed, the photosensitive-ink for not having exposure on mould is washed.Preferably, Mu Pattern depth is formed on the mould for the gangsters of 0. 10-0. 30.
Preferably, the step（Two）Injection molding specifically include following steps：
1) plastic material, is selected first and its physical parameter is determined, it is then determined that the ground color of plastic cement products；
2), by mould installion on injection molding machine and plastic material be put into drying dry, then setting is with raw material and the adaptable technological parameter of required plastic cement products on injection molding machine, the injecting products needed by machine and technological parameter；
3) product appearance, is checked, is removed it if having the mouth of a river.
The step 2) in molding proces s parameters be：The temperature of mould, raw material stoving temperature and drying time, the plasticization temperature of raw material are set according to raw material physical parameter, the rotating speed and back pressure of screw rod, gauge position, switching position are set according to the feature of product, injection pressure, speed, dwell pressure, time, cool time, the position of mould open/close mould is set according to the feature of mould and product, speed, pressure, the position of ejection, pressure and speed.
Preferably, the step（Three）Spray painting include step in detail below：
1) final color of plastic cement products, is determined first, it is then determined that required selection painting color, and determine the physical parameter of paint；
2), the position that need not be painted on product is shielded；
3), the physical parameter according to paint is debugged with diluent is painted, and the paint debugged is uniformly sprayed on product；
4), the product after spray painting is put into baker and toasted；
5) shielding on product, is removed.
Preferably, above-mentioned steps 3) in paint and the weight ratio of diluent be 1:1, the coating thickness of spray painting is 5_25mm, and preferably 8-15 Lan, the oven drying temperature is 50_80 °C, and baking time is 10-20 minutes.
The step（Four）In product polishing can be using such as manually or electrically mode be carried out, the abrasive material used in bruting process can also be selected as needed, as long as the polishing effect to be reached can be played, preferably, the polishing of the product is mainly included the following steps that：
1) sand paper of model, is adapted to according to the surface requirements of product and the characteristic selection of paint first, the sand paper after then will confirm that is immersed in water；
2), uniformly polished on product surface with the sand paper soaked；
3), cleaning products, are then packed.
Preferably, the step 2 of product bruting process) and step 3) between also comprise the following steps, by after polishing product cleaning after spray a floor height gloss oil paint again：Diluent：The weight ratio of curing agent is 100: 20:52 mix paint, and the coating thickness of paint is 15_25um;Product after spray painting is put into baker and dried, drying condition sets oven drying temperature according to the physical parameter of paint as 60_80 °C, baking time is 30-60 minutes.
Compared with prior art, the beneficial effects of the present invention are：
