Description

Pattern color spraying method for plastic wire ring mat

The invention relates to a plastic wire ring mat used in front of or in a door, and more particularly to a pattern color spraying method for a plastic wire mat.

In daily life, the floor mat used in front of or in the room is both a mat product and a decorative item. At present, there are many types of floor mats on the market, and a representative one is a plastic wire mat. The floor mat is generally formed by composite bonding of a wire loop layer and a substrate layer (which may also be composed of a wire loop layer alone), wherein the backing layer is a plastic foam layer, and the wire loop layer is extruded from a plastic such as PVC, PE or PP. The wires are randomly stacked and crimped. The wire diameter is generally between 0.6 and 3 mm, and the layer thickness is generally between 0.3 and 3 cm. The overall shape is hollow and highly elastic, and can absorb the dirt of the sole such as granular sediment. Although the mat has no wool mats and fabric mats, it is luxurious, but it is dirt-resistant, easy to clean, and cheap, so it is very popular among consumers.

The pattern and color of the plastic wire mats are significantly decorative and are the selling points that attract consumers' attention. All along, many manufacturers are striving to develop a series of plastic wire mat products with rich colors and remarkable decorative effects and charm. Therefore, how to make patterns and colors on a plastic wire mat has been a concern of those skilled in the art. At present, there are many existing techniques for making patterns and colors on plastic wire mats, such as the puzzle method (see Chinese patent CN1386464A), the mapping method (see Chinese patent CN201734455U), the hot pressing method and the painting. Mapping method (see Chinese patent CN2770519Y) and so on. The closest to the content of the present invention is the paint drawing method. The basic content of the paint drawing method is to use a template with a hollow pattern to cover the area that does not need to be sprayed, and spray the paint on the floor mat at the hollow pattern. When the paint pattern layer is attached to the surface of the wire mat, a layer of transparent resin is sprayed. The protective layer forms a pattern on the surface of the wire mat. This method uses paint as the spray material. Only one color can be used for each spray. When the design pattern uses different colors in different areas, multiple templates are needed to achieve this by fractional and color separation. At present, although some manufacturers are trying to use this method in the field, the following problems are commonly encountered:

1. When making a color pattern, it is necessary to make a plurality of templates, which are realized by fractional and color separation spraying, and each time after spraying, it is necessary to wait for the paint to dry before the next spraying, so the process is complicated, time-consuming, and productive. Low and high cost. Especially when making complex patterns of more than three colors, the situation is even more serious.

2. This method cannot be used for full-color painting in a mixed color mode. Only one color of paint can be used for each spray. A color pattern can only be achieved by using multiple colors in a puzzle. Therefore, the pattern is rough, and only the color block effect can be exhibited, the color effect is poor, the visual effect is relatively dull, and the stereoscopic effect is lacking.

3. The amount of paint used during the spraying process is difficult to control. If the amount of paint is too small, it is difficult to spray through the inside of the hollow wire loop layer, resulting in uneven coloration of the pattern, which seriously affects the visual effect. If the amount of paint is too much, because the paint material is thick and sticky, it is easy to pile up on the surface of the ring layer and agglomerate. It is easy to fall off after being cracked, and the heavy one affects the scraping and sediment function of the original plastic wire ring mat.

In short, due to the above problems, the paint drawing method is difficult to be widely promoted and applied in the field.

The main object of the present invention is to provide a pattern color spraying method for a plastic wire ring mat, aiming at developing a new color jet drawing technical method for a plastic wire ring floor mat product, which solves the backward technology, low production efficiency and pattern color. Poor quality and other issues.

In order to achieve the above object, the method for color inkjet printing of the plastic wire ring mat of the present invention comprises:

(1) Color selection of plastic wire mats

Selecting a white or light colored plastic wire mat as a color jet object, wherein the white color is colorless; the light color is based on printing four primary colors, namely cyan, magenta, yellow, black, and each primary color The standard darkness concentration ratio is 100% as a reference, and the color of one of the following two colors is met: the first color is any one of the four primary colors, and the ratio of the depth to the light is less than or equal to 30% of the reference; The two colors are mixed colors of at least two of the four primary colors, and the sum of the depth and concentration ratios of the various primary colors is less than or equal to 30% of the reference;

(2) Pattern printing method of plastic wire ring mat

For white or light colored plastic wire mats, the following steps are included:

The first step is to spray the pre-treatment liquid coating

A prepress treatment solution compatible with a weak solvent ink is used as a spray material. The spraying device sprays the front surface of the plastic wire ring mat in a uniform mist form, so that the surface of the plastic wire ring on the plastic wire ring mat covers the prepress treatment liquid coating, and the coating is solidified by standing or heating after spraying. Plastic wire ring surface;

The second step, spraying the painted pattern

Using colored weak solvent ink as the spraying material, the front surface of the plastic wire ring mat coated with the pre-treatment liquid coating is sprayed by a color inkjet printer in a predetermined pattern according to a preset pattern until the pattern is sprayed; In the process, the nozzle of the color inkjet printer is 3~5 mm away from the top surface of the plastic wire ring mat, and is sprayed vertically downward by the ink incremental spraying method or the ink increasing injection method; the ink incremental spraying method refers to the pair For each pixel of the pattern, under the premise of maintaining the normal number of ejections, the amount of ink per ejection is increased by 50~200% based on the common dosage; the ink increasing injection method refers to each pixel of the pattern. In terms of points, the nozzle increases the number of injections by 2 to 4 times based on the number of ordinary injections while maintaining the usual amount of ink for each injection;

The third step, heat curing

The plastic wire ring mat of the inkjet color pattern is placed in an oven or heated and solidified by a drying tunnel, so that the color pattern of the inkjet is firmly adhered to the surface layer of the plastic wire ring mat and integrated into one.

The relevant content in the above technical solutions is explained as follows:

1. In the above scheme, the "printing four primary colors" refers to the four primary colors used for printing, that is, C for cyan, M for magenta, Y for yellow, and K for K. black. In fact, all colors can be mixed by printing four primary colors in different shade ratios. This approach can be used in the present invention to define the concept of light color.

2. In the above scheme, the "prepressing solution" may also be referred to as a coating liquid, a printing treatment liquid, a special coating liquid, and the like. It is a pre-treatment liquid before inkjet printing, and its role is mainly to improve the quality and adhesion of inkjet printing. Prepress solutions are typically highly transparent liquids and are currently available on the market directly through normal sales pipelines. It is understood that this product can be divided into three categories, namely ABS, metal and special stretch materials, of which ABS is suitable for most plastic materials such as acrylic, PC, PVC, leather, plexiglass, film, etc. Metals are generally suitable for materials with smooth surfaces such as metal, hardware, glass, ceramics, crystal, marble, etc. Special stretches are suitable for materials that have stretchability and can be stretched with the material of the object, such as rubber materials. The above three types of prepress treatment liquids can be applied to the plastic wire ring mat of the present invention.

3. In the above scheme, the "weak solvent ink" is an inkjet ink interposed between an aqueous ink and a solvent type ink. Low-solvent ink, also known as ECO-solvent ink or Light solvent ink, is a new type of outdoor solvent inkjet that has been popular in the outdoor solvent-based digital inkjet market in recent years. It has high safety and low performance. Volatile, low to slightly toxic and high flash point. At present, weak solvent inks are commercially available through the normal sales pipeline, and are conventionally a combination of four colors or more. The common brands in the domestic market are Qi Caihui (Foshan Nanhai Mojia Consumables Co., Ltd.), Huineng (Guangzhou Ouke Communication Technology Co., Ltd.), Youdian (Chengdu Youdian Technology Co., Ltd.), Julie (Jinan Ju Li Digital) Technology Co., Ltd.), Ling Feng (Zhuhai Hao Cai Digital Technology Co., Ltd.), INKWIN World (Shanghai Yingwei Inkjet Technology has Limited company), excellent Nerojet (Shenzhen Nuojie Technology Co., Ltd.) and so on. The weak solvent ink currently available on the market can be applied to the plastic wire mat of the present invention.

4. In the above scheme, the printing resolution is between 240 dpi and 1440 dpi when printing the color pattern in the second step, preferably between 360 dpi and 720 dpi.

5. In the above scheme, the heating in the third step can be selected from 80 ° C to 120 ° C, and the heating and curing time is between 20 seconds and 300 seconds.

The invention designs a method for spraying a color pattern on a plastic wire ring mat by using modern inkjet printing technology, and the method solves the following three problems: the first is the problem of opacity, and the color pattern is formed on the plastic wire ring mat by using inkjet technology. The use of inkjet is a weak solvent ink. Because the weak solvent ink has poor opacity effect compared with the paint, it is usually impossible to shield the material color of the plastic wire ring mat itself by spraying on the plastic wire ring, so that the color of the ink is affected by the mixing of the material color of the plastic wire ring itself, and becomes The color is completely different from the primary color of the weak solvent ink, and the pattern is not clear enough. In order to solve this problem, the present invention has selected a white or light colored plastic wire mat as a color jet object, thereby solving this problem better.

The second is the problem of inkjet printing of non-planar and hollow wire loops. The wire loop layer on the plastic wire ring mat is a random stack of plastic extruded monofilaments, which is a non-planar hollow three-dimensional structure, and the gap is large. If the ink jet is used to make the pattern, the ink jet diffusion principle is in the wire loop. The lower the internal position, the more blurred the pattern becomes, the larger the ink dot distance is, and the lower the part is, the easier it is to be covered by the upper layer wire ring. The color development effect is poor, and the color of the substrate is easily exposed, resulting in a generation of the wire mat. More white, the pattern will be intermittent, no overall sense. In order to solve this problem, the present invention employs an ink incremental jetting method or ink incrementing. The spraying method is sprayed vertically downwards to make the ink penetrate into the inside of the wire loop layer, so that the wire loops of different heights and positions can be completely inked, thereby solving the problem well. Although the invention is directed to a non-planar and hollow wire loop layer, the layers on different high and low wire loops can be gathered to form a complete pattern, and a complete pattern can be seen from a certain height of each view angle, and the plastic wire ring cannot be printed. The lack of color development. Moreover, the ink layer formed on the wire ring material is very thin, does not change the original structure of the floor mat, does not destroy the original functionality, and the effect is like the original color of the wire loop.

The third is the problem of pattern fastness. The plastic wire ring material does not absorb ink, and the ink is sprayed on the circular arc surface of the wire to cause sputtering and ink transfer. Therefore, the ink can not be imaged on the wire material, so the pattern is not formed, and the color rendering effect is poor. Poor adsorption, easy to decolorize, not wear resistant. In order to solve this problem, the present invention sprays a layer of pre-treatment liquid with the same or similar physical properties as the wire loop layer on the wire loop layer of the plastic wire ring mat, and uses the pre-treatment liquid layer as a carrier to spray the weak solvent ink. The layer is firmly attached to the wire loop layer, which solves this problem better.

Since the present invention solves the above technical problems well, it has the following advantages and effects as compared with the prior art:

1, the preparation is simple, the pattern and color production is not limited, even full-color photos can be made on the plastic wire ring mat.

2, the pattern is clear and the color effect is good.

3, the pattern is firm, wearable, stepping on without decolorization.

4, advanced production technology, high production efficiency, especially suitable for mechanization and automated mass production.

The present invention will be further described by way of specific embodiments: the pattern color spray method of the plastic wire ring mat of the present invention is composed of the following two parts:

The first part of the color selection of plastic wire mats

Selecting a white or light colored plastic wire mat as a color jet object, wherein the white color is colorless; the light color is based on printing four primary colors, namely cyan, magenta, yellow, and black, and each The standard shade ratio of the primary color is 100% as a reference, and the color of one of the following two colors is met: the first color is any one of the four primary colors, and the ratio of the depth to the light is less than or equal to 30% of the reference; The second color is a mixed color of at least two of the four primary colors, and the sum of the depth and concentration ratios of the various primary colors is less than or equal to 30% of the reference;

The second part of the pattern of plastic wire ring matting technology

For white or light colored plastic wire mats, follow these steps:

The first step is to spray the pre-treatment liquid coating

The pre-press treatment liquid matched with the weak solvent ink is used as the spraying raw material, and the front surface of the plastic wire ring mat is sprayed in a uniform mist form by the spraying device, so that the surface of the plastic wire ring on the plastic wire ring mat covers the pre-press treatment. Liquid coating, after spraying, the coating is cured on the surface of the plastic wire ring by standing or heating.

The second step, spraying the painted pattern

Using colored weak solvent ink as the spraying material, according to the preset pattern, The front side of the plastic wire ring mat coated with the pre-press treatment liquid coating is sprayed by a color inkjet printer in a progressive scanning manner until the pattern is sprayed; in the inkjet printing process, the nozzle of the color inkjet printer is at a distance from the top of the plastic wire ring mat. The surface is 3 to 5 mm, and is sprayed vertically downward by the ink incremental ejection method or the ink secondary injection method.

The ink incremental spraying method means that for each pixel of the pattern, the nozzle uses a common injection number, and the amount of ink injected per time is increased by 50 to 200% based on the common amount.

The ink sub-injection method means that for each pixel of the pattern, the nozzle increases the number of injections by 2 to 4 times based on the number of ordinary injections while maintaining the normal amount of ink for each injection.

In the second step, the printing resolution of the inkjet color pattern is between 240 dpi and 1440 dpi, and the printing resolution is preferably between 360 dpi and 720 dpi.

The third step, heat curing

The plastic wire ring mat of the inkjet color pattern is placed in an oven or heated and solidified by a drying tunnel, so that the color pattern of the inkjet is firmly adhered to the surface layer of the plastic wire ring mat and integrated into one. In the third step, the heating is in the range of 80 to 120 degrees Celsius, and the heating and curing time is between 20 seconds and 300 seconds. After heating, the fusion curing effect will be strengthened, and the pattern is integrated with the wire loop, and the firmness and wear resistance can reach the standard of the tread pad.

The content of the present invention will be described below with reference to the accompanying drawings:

1. Layered description of plastic wire ring mat after inkjet color pattern

The first figure is a layered schematic diagram of a plastic wire ring mat after printing a color pattern according to an embodiment of the present invention. It can be seen from the figure that the plastic wire ring mat after printing the color pattern is from below. The upper layer is composed of four layers, the first layer is a gray substrate layer 1, the second layer is a white or light colored plastic wire ring layer 2, the third layer is a pre-treatment liquid coating layer 3, and the fourth layer is a weak solvent ink inkjet printing layer. Layer 4. The color inkjet object of the present invention is a plastic wire ring mat. Generally, the plastic wire ring mat is formed by composite bonding of the wire loop layer and the backing layer, or may be composed of a wire loop layer alone, and the wire loop layer is made of PVC, PE or PP. The plastic extruded monofilaments are randomly stacked and crimped. The wire diameter is generally between 0.6 and 3 mm, and the layer thickness is generally between 0.3 and 3 cm. The overall shape is hollow and highly elastic. The plastic wire mat of the present invention is generally white or light colored, and may be a substrate layer or a substrateless layer, and the substrate layer is not limited to the substrate layer material type.

When the color of the plastic wire ring mat is light, the color of the printed pattern must be darker than that of the plastic wire mat. Under normal circumstances, the color of the printed pattern is darker than the color of the plastic wire mat to highlight the pattern effect. . For a plastic wire mat with a substrate layer, the color of the substrate layer is optimal, but not limited to black (k) 50% gray, other colors are lower, and the brightness is 50% or higher. Since the plastic wire ring mat is composed of a three-dimensional wire ring, the underlying substrate layer is visually the background layer of the wire ring layer, and the wire ring layer will form a shadow on the surface of the substrate layer, and the underlying wire ring color The darker the color will appear, the easier the color of the wire circle will be integrated into the color of the substrate layer. Therefore, if the brightness or chroma of the substrate layer is too high or too low, the pattern printed on the wire ring will be visually disturbed through the wire gap. The use of a substrate layer with a gray or chroma brightness is better integrated into the shadow of the inner and lower layers of the inside of the loop, diluting the whiteness left on the bottom, reducing the problem of whitening, and enhancing the pattern on the ring.

2. Description of the process of color inkjet technology for plastic wire ring mats

The second to fifth figures show the technical process of the pattern color spray of the plastic wire ring mat, wherein the second figure shows the plastic wire ring mat before the pattern color spray, the plastic wire mat is made of white or light colored plastic ring The layer 2 and the gray substrate layer 1 are bonded together. The third figure shows the application of a pre-treatment liquid coating to the plastic wire mat. As can be seen from the third figure, the pre-press treatment liquid is sprayed on the white or light-colored plastic wire loop layer 2 on the front side of the plastic wire ring mat by the spray device head 5 to form the pre-press treatment liquid coating 3. The fourth figure shows the color pattern of the plastic wire mat floor. As can be seen from the fourth figure, the weak solvent ink is printed on the front side of the plastic wire ring mat by the color inkjet printer head 6 in which the weak solvent ink inkjet layer 4 falls on the white surface coated with the pretreatment liquid coating 3. Or a light colored plastic wire loop layer 2. The increment or increase of the ink 7 is indicated to increase the coating area of the inside of the loop and the sides and the bottom surface. The fifth figure shows that the plastic wire mat is sprayed with a color pattern and then heated and solidified to accelerate the curing speed and improve the firmness of the pattern.

3. Description of ink increment or ink increase injection

The sixth figure is a schematic diagram of the common amount of ink for each pixel of the pattern, and the seventh figure is a schematic diagram of the ink incremental injection. As can be seen from the comparison between the seventh and sixth figures, for each pixel of the pattern, the amount of ink per ejection increases under the premise of maintaining the number of ordinary ejections, so the ink point of the seventh figure is significantly larger than The ink dot of the sixth figure. The eighth figure is a schematic diagram of the ink-increasing injection. From the eighth figure, it can be seen that for each pixel, the nozzle increases the number of ordinary injections by 2~4 on the premise of maintaining the normal amount of ink for each injection. Secondary injection. In the present invention, the purpose of the ink increment or the ink increase injection is to increase the ink loading area of the wire loops at different high and low positions. Because the plastic wire mat is a three-dimensional knot of round plastic filaments Structure, not a solid plane, like a myriad of layers filled with hollow canvases, the focus of inkjet is to make the wire loops made up of three-dimensional hollows from the surface layer to the interior of each part, so that the pattern can be formed on the three-dimensional wire loop, and Forming the whole visually. To achieve this, the present invention employs a special ink increment or ink sub-injection method to increase the amount of ink jet or the number of ink jets at the same ink dot position, thereby increasing the ink picking rate inside the three-dimensional loop.

4. The conventional inkjet method is compared with the visual effect of the ink increment or the ink increase injection of the present invention.

The ninth picture is a visual effect diagram of the conventional inkjet method. As can be seen from the ninth figure, in the conventional ink-jet method, in the five places a, b, c, d, and e, there is no ink at the b and d, so the vision is an incomplete figure. The reason is that the traditional inkjet method is designed for flat inkjet printing. Since the ink amount is small, the ink can only adhere to the top of the material, and the other parts except the top cannot be taken into consideration, so the pattern after the spraying may be intermittent, leaking and whitening. .

The tenth figure is a visual effect diagram of the ink increment or ink sub-injection method of the present invention. As can be seen from the tenth figure, the visual form is a complete pattern using the ink increment or ink sub-injection method of the present invention. The reason is that the ink spot increment or the incremental spray method can increase the coating area of each side including the top, so that the ink can penetrate into the irregular hollow material, so the plastic wire mat can be observed from various angles, and the whitening problem can be Minimized to a minimum.

The eleventh figure is a schematic diagram of the viewing angle of the ink increment or ink sub-injection mode of the present invention. In the eleventh figure, A~J indicates the connection of ten different height parts. The top ink inking portion 8 is shown to indicate the side ink inking portion 9. If the ink pattern is increased by the ink increment or the ink sub-injection method of the present invention, the ink can be penetrated into the hollow inside of the three-dimensional wire loop, and the image of the inner side is improved by 90 degrees on the side. Therefore, when viewed from the top to the bottom from different angles, even if the three-dimensional wire loop is hollowed out, the complete effect of the pattern can be visually restored, thereby greatly reducing the phenomenon of pattern discontinuity, leakage and whitening.

The twelfth figure is an X-view effect diagram in the eleventh figure; the thirteenth figure is the Y-view effect diagram in the eleventh figure; and the fourteenth figure is the Z-view effect diagram in the eleventh figure. Although A~J has ten different height parts, the pattern has a complete effect from the three different perspectives of the twelfth to the fourteenth.

In summary, in the present invention, the ink vertical increment or incremental injection technique is specifically designed for the three-dimensional hollow plastic wire mat to increase the amount of ink ejection or the number of ink ejection at the same ink jet point position, thereby improving the ink in the ink. The color area of different heights and positions inside the three-dimensional wire loop is not limited to the surface layer of the plastic wire ring mat. Because of the three-dimensional hollow plastic wire ring structure, like a broken canvas with many layers, improving the inkjet precision is only to improve the fineness of the surface layer of the wire loop, and the amount of ink dots falling from the hollow portion of the surface layer is dispersed to different high and low wire loops. The amount of ink in each position is not enough to show the overall pattern. The reason is that the ink ejected from the nozzle spreads conically from top to bottom, and the lower the position of the inking point, the more the whitening distance is white, so that many whiteness will appear inside the coil, and the invention adopts vertical increment of ink or The sub-injection technique only needs to use a lower ink-jet precision, and the ink increment or the sub-injection at the original ink dot position can increase the multi-level color ratio of the ink deep into the three-dimensional plastic wire ring. Ink increment or increase spray The shot will increase the rate of ink in the white position, so that the original ink point is enlarged and the ink dot spacing is reduced to reduce the whitening phenomenon. This technology is designed for inking imaging inside a hollow, multi-slit, multi-layered three-dimensional wire material with a thickness to improve the pattern effect. The sprayed pattern has a continuous picture from different perspectives.

The above is only the preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and any one of ordinary skill in the art will be able to carry out the invention without departing from the technical description disclosed above. Modifications, modifications, or equivalent design changes made by the technical scope of the present invention should be covered by the technology of the present invention.
