Antique bricks, with their unique texture, color and pattern, can create a nostalgic and warm atmosphere, and are suitable for spaces of various styles, from rural pastoral to modern industrial style. At present, due to the advancement of production technology, such as high-definition inkjet printing and glaze treatment, antique bricks can realistically reproduce the texture of materials such as stone, wood and fabric, while maintaining the durability and easy cleaning of tiles. At present, the pattern of plastic floor is printed by digital inkjet printing, but the 3D printed pattern is at a disadvantage in embossing, and the rock texture is not realistic enough, and the embossing depth cannot meet the requirements of real ceramic tiles and ancient tiles.

BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Figure 1 This is a schematic diagram of the process of Example 2 of the present invention. DETAILED DESCRIPTION

[0019] In order to make the technical solution of the present invention clearer, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] Example 1

[0021] A crack-resistant and wear-resistant paint is mainly used to produce a pattern similar to a real rock on the floor. A layer of crack-resistant and wear-resistant paint is coated on the base material of the base plate so that the rock pattern pre-printed on the base material of the base plate will not crack when hot-pressed.

[0022] The structure of the base plate with rock pattern consists of, from bottom to top, base plate substrate, anti-cracking and wear-resistant paint, and topcoat.

[0023] The surface of the floor substrate is printed with a rock pattern, and the rock pattern of the floor substrate is covered with anti-cracking and wear-resistant paint for protection.

[0024] Compared with conventional wear-resistant paints, crack-resistant paints have better crack resistance and will not produce cracks during hot pressing.

[0025] The composition ratio of anti-cracking and wear-resistant paint is: polyurethane: 25-35%; polyester: 5-10%; functional monomer: 20-30%; aluminum oxide: 20-30%; wear-resistant powder: 5-10%; adhesion promoter: 1-3%; initiator: 3-7%; auxiliary agent: 1-3%.

[0026] When making anti-crack and wear-resistant paint, the above materials need to be mixed, but the mixing needs to be in a certain order to ensure the anti-crack and wear-resistant properties of the anti-crack and wear-resistant paint.

[0027] When mixing, firstly, the polyurethane, polyester and functional monomer are uniformly mixed, and then the auxiliary agent is added after the mixing is completed, and then aluminum oxide and wear-resistant powder are added after uniform mixing again, and then the adhesion promoter is added, and finally the initiator is added.

[0028] By mixing in the above order, the materials can be mixed more fully.

[0029] Example 2

[0030] Combined with Figure 1 , a production process for making flooring using crack-resistant and wear-resistant paint:

[0031] Including making the base material, digital printing of patterns, coating the surface of the base, embossing, and sawing and grooving.

[0032] Making the base material:

[0033] The anti-crack and wear-resistant paint can be used with any baseboard to form a floor with a rock pattern. Therefore, the pattern of the baseboard substrate can be selected from a variety of baseboard substrate materials to adapt to the use environment of various floors. The substrate material is preferably SPC, PET, TPU, and PP materials.

[0034] The base material of the base plate also needs to be combined with some auxiliary materials when making the base plate to enhance the performance of the base plate.

[0035] Specific production of the base plate:

[0036] Prepare the materials for making the bottom plate substrate, mix the bottom plate substrate materials in a mixer, and put the mixed materials into an extruder, and the extruder is preferably a 92 extruder.

[0037] The extruder is turned on to extrude the base plate substrate of corresponding thickness according to the designed size and thickness of the base plate substrate.

[0038] The extruded floor substrate is cooled to form a floor substrate for use in making flooring.

[0039] Digital Printing Pattern:

[0040] After the base material of the base plate is produced, the surface of the base material is polished with sandpaper to make the surface of the base material smooth so that the white paint can be fully combined with the base material.

[0041] After the base plate substrate is sanded, a layer of white paint is coated on the sanded surface of the base plate. The white paint is used to make the rock pattern printed on the base plate substrate by the digital printer clearer.

[0042] After the white paint film solidifies, the base plate substrate is transported to the digital printer to print the rock pattern.

[0043] Printing rock patterns: rock patterns are printed on the surface of the base plate substrate by digital printing, which can accurately and quickly print rock patterns on the base plate substrate.

[0044] Bottom plate surface coating:

[0045] After the pattern is printed on the base material, anti-cracking and wear-resistant paint and topcoat are coated on the rock pattern in sequence.

[0046] The anti-cracking and wear-resistant paint has the advantages of wear-resistant paint and forms a wear-resistant layer on the base material of the base plate. At the same time, since the base plate base plate needs to be hot-pressed in subsequent processes, the anti-cracking and wear-resistant paint will not produce cracks during hot pressing to affect the effect of the rock pattern.

[0047] After the anti-crack and wear-resistant paint is coated and solidified, a layer of topcoat is applied on the anti-crack and wear-resistant paint. The topcoat is preferably a digital topcoat, which is more compatible with the printed pattern and has less impact on the pattern. The topcoat can ensure the physical properties of the floor surface and ensure the glossiness of the finished baseboard surface.

[0048] The coating of crack-resistant and wear-resistant paint and topcoat is preferably solidified by UV light.

[0049] Pressed embossing:

[0050] After the anti-cracking and wear-resistant paint and topcoat are applied, the base material of the base plate is pressed. The pressing process can make the rock pattern on the base plate look realistic. The pressing process includes two consecutive pressing processes, hot pressing and cold pressing.

[0051] When pressing the base material of the bottom plate, a hot press is selected for hot pressing. The steel plate on the hot press that is in direct contact with the floor base material needs to correspond to the rock pattern, so that embossing is pressed on the base material of the bottom plate in the form of hot pressing. The embossing can make the floor with the rock pattern more realistic.

[0052] The specific hot pressing process of the base plate substrate: hot pressing is first performed, and then cold pressing is performed. Hot pressing is used to press out embossing and truly display the rock embossing. Cold pressing sets the embossing and prevents the rock pattern from changing color.

[0053] The temperature of hot pressing is maintained at 100-120 degrees Celsius, and the hot pressing time is 15-20 minutes. The hot pressing is a gradual pressure increase, and the pressure is increased from low to high. The hot pressing pressure is divided into three sections, which are 7MPa, 8MPa, and 9MPa respectively. The three-section pressure of hot pressing is continuous, and the overall time of the three sections of gradually increasing pressure is 15-20 minutes. The hot pressing time changes according to the hot pressing temperature, and the auxiliary hot pressing effect can also be changed accordingly.

[0054] Through three-stage pressurization, the embossed pattern can be made more coherent and more realistic.

[0055] After hot pressing, cold pressing is performed. After cold pressing, the embossing can be stably preserved and is not easy to deform.

[0056] The cold pressing temperature can be room temperature, and the cold pressing pressure is also a three-stage pressure with gradual pressurization. The cold pressing pressure is 9MPa, 11MPa, and 13MPa from low to high. The cold pressing pressure is also continuously pressurized, and the overall duration of the cold pressing is also 15-20 minutes.

[0057] After the embossing is pressed, not only can the required embossing depth be obtained on the base material of the baseboard, but also the rock pattern can be ensured and will not change color and affect the effect of the finished floor.

[0058] Saw board slotting:

[0059] After the cold pressing is completed, the finished base plate needs to be sliced ​​and grooved. Qualified finished products can be obtained by slicing and grooved the plate according to design requirements.

[0060] Compared with conventional digital wear-resistant paint, anti-crack wear-resistant paint can better prevent cracks from appearing on the surface of the base plate during hot pressing.

[0061] Test comparison:

[0062] Comparison method: select the same base plate substrate, sand it, digitally print out the rock pattern, and coat the rock pattern with digital wear-resistant paint and anti-cracking wear-resistant paint respectively. Use the same process standard bricks to press and emboss the two base plates with different paints, and then coat the same topcoat on the base plate substrate after pressure, and then compare the surfaces.

[0063] The coating solidification parameters of digital wear-resistant paint and anti-cracking wear-resistant paint are as follows:

[0064] (1) Surface coating: digital wear-resistant paint, weight 110g / ㎡, curing energy 150mj / c㎡, digital topcoat, weight 8g / ㎡, curing energy 1000mj / c㎡.

[0065] (2) Surface coating: anti-cracking and wear-resistant paint, weight 110g / ㎡, curing energy 800mj / c㎡, digital topcoat, weight 8g / ㎡, curing energy 1000mj / c㎡.

[0066] After hot pressing using the same hot pressing process, observation with the naked eye shows that although both samples (1) and (2) can obtain real rock textures, cracks appear on the embossed surface of floor sample (1), with 50-100 cracks per square meter, each crack is 20-30 mm long and 0.05 mm wide; there are no cracks on the surface of floor sample (2).

[0067] Products made with crack-resistant and wear-resistant paint:

[0068] 1. Meet the requirements of EN16511, class 33, shrinkage rate ≤ 0.25%.

[0069] 2. The alignment error is controlled within 1.5mm.

[0070] 3. The edge drop and embossing depth reach 0.15mm.
