Description

Matt chamfering method and plate manufacturing process using the same Technical Field

[0001] The present invention relates to the technical field of plate processing, and in particular to a matte chamfering method and a plate manufacturing process using the method. Background Art

[0002] Over the years, floor chamfering has evolved at different stages, driven by market trends and technological advancements. Chamfering can improve the appearance of floors, making them appear more natural. Different chamfer types can also produce different effects, and depending on the material or intended use of the floor, the chamfering method also varies. For example, the surface of plastic flooring requires a matte coating with a matte finish of 2-3 degrees. After coating, the finished product is then sliced ​​and chamfered to obtain the finished product. At this point, the chamfer will become shiny, affecting the overall appearance. To address this issue, the market uses special tools to mechanically polish the wear-resistant layer to create a matte chamfer. However, the polished chamfer easily becomes shiny after wiping, and the chamfer created in this way is difficult to clean due to dust. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a matte chamfering method and a board manufacturing process using the method, which solves the problem that the chamfered corners of plastic floors are prominent and shiny, affecting the overall appearance of the board.

[0026] FIG1 is a schematic diagram of a process of embodiment 1 of the present invention;

[0027] FIG2 is a schematic diagram of chamfering according to embodiment 1 of the present invention. DETAILED DESCRIPTION

[0028] In order to further understand the content of the present invention, the present invention is described in detail with reference to the accompanying drawings and embodiments. Example

[0029] In conjunction with Figures 1-2, a board manufacturing process is shown, in which the board is formed by laminating a base material layer, a middle material layer, a color film and a wear-resistant layer in sequence, from bottom to top, they are the base material layer, the middle material layer, the color film and the wear-resistant layer, and the wear-resistant layer needs to be matte chamfered.

[0030] Formula for making base material and middle material base material:

[0031] The medium material requires 14.9 parts of polyvinyl chloride resin, 79 parts of stone powder, 5.8 parts of plasticizer, and 0.3 parts of stabilizer, which constitute 3.8 times the medium material.

[0032] The base material requires 26.1 parts of polyvinyl chloride resin, 67 parts of stone powder, 6.5 parts of speed increaser, and 0.4 parts of stabilizer, which constitute 2.0 times the base material.

[0033] Among them, the middle material and the base material play a good supporting and balancing role in the floor. The multiple of the middle material and the base material is the mass ratio of stone powder to the sum of polyvinyl chloride resin and plasticizer. The larger the multiple value, the more stone powder content, so the harder the board is, and the corresponding board will be more brittle. The conventional choice of middle material is 2.8 times, 3.0 times or 3.4 times, and the conventional choice of base material is 1.0 times, 1.2 times or 1.8 times. This technical solution adopts 3.8 times of middle material and 2.0 times of base material, which can save costs.

[0034] The various prepared materials of the base material and the middle material are mixed in proportion, firstly stirred and kneaded, and then open-mixed and calendered to prepare the middle material and base material for processing the floor.

[0035] The color film layer and the wear-resistant layer are widely used in the market and can be purchased and used directly.

[0036] The thickness of the wear-resistant layer cannot be less than 0.5 mm to ensure that the finished floor has good wear resistance and extend its service life.

[0037] The prepared base material, middle material combined with color film and wear-resistant layer are put into the press in turn for hot pressing and bonding. Each layer is bonded and cold pressed to ensure that each layer is firmly bonded to form a semi-finished board. The first curing is for 24 hours. After sufficient curing, the coating is carried out. Matte paint is selected for the coating, and the glossiness is super matte 2-3 degrees.

[0038] The first curing time is 24 hours. The curing step is very important and cannot be omitted. If you do not do the curing before laminating, it is easy to cause bubbles to form between the wear-resistant layer and the color film.

[0039] A layer of super matte UV paint is applied on the surface of the board to enhance the surface's scratch and wear resistance while improving the product's aesthetics. The paint gloss requirement is super matte 2-3 degrees.

[0040] During lamination, the surface temperature of the board needs to be greater than 15 degrees, and the paint temperature is 20-35 degrees to make the paint surface more uniform and smooth.

[0041] Super matte UV paint needs to be coated twice, divided into two layers of paint, primer and topcoat. First spray the primer, the weight of the primer is 15±2 grams, preferably 15 grams. After spraying, it needs to be cured, and the curing energy is 1300-1600mj / cm 2 When the primer is completely cured, spray the topcoat. The topcoat weight is 13±2 grams, preferably 13 grams. Curing is carried out after spraying. The curing energy is 150-300mj / cm 2 The paint surface formed by two sprayings has good wrapping and corrosion resistance for the board, which can extend the service life of the board.

[0042] Tempering is carried out simultaneously to make the product size more stable.

[0043] The tempering method is that the plate flows into the tempering equipment, and the plate moves at a stable speed in the tempering equipment. The temperature in the drying tunnel of the tempering equipment is about 125 degrees, and the outlet temperature is 110-115 degrees.

[0044] After the plate flows out of the tempering equipment, it needs to be cooled by water to reduce the temperature of the plate to 40-50 degrees, and then cooled by fans to reduce the temperature of the plate to 25-35 degrees. The whole tempering process takes 3 minutes.

[0045] After tempering is completed, the plate is cured again, and the curing time is also 24 hours. Then the plate is sliced ​​and finally processed.

[0046] When slicing, a certain size should be reserved for chamfering and beveling as an allowance for chamfering and beveling.

[0047] Use a fixed knife for chamfering, and the requirements for chamfering

[0048] ①The chamfering angle is tilted 10 degrees from the horizontal to prevent white edges from appearing during chamfering;

[0049] ②Chamfer width 1.2mm;

[0050] ③The product’s wear-resistant layer is 0.5mm or above.

[0051] After splitting, apply chamfered matte paint to the side edges of each base plate.

[0052] First, place the semi-finished board face up on the assembly line of the oiling equipment, that is, the wear-resistant layer faces up.

[0053] Adjust the support table height and chamfer gear angle according to product specifications to ensure uniform coating.

[0054] Before pouring the chamfer paint into the oiling device, you need to clean the oiling device first. Since the matte chamfer paint is a water-based transparent paint with a glossiness of 2-3 degrees, it is easily contaminated by other color paints. At the same time, pay attention to the viscosity of the matte chamfer paint and stir it thoroughly before oiling.

[0055] The paint flows to the oiling nozzle and is rolled to achieve a matte finish.

[0056] When oiling, the oiling device is used in conjunction with infrared lamps, which can quickly dry the paint.

[0057] First, oil the short side. The transport speed of the short side is 15-20m / min. The oil is quickly dried by the infrared lamp. Then oil the long side. The transport speed of the long side is 45-55m / min. The process is the same as the short side. The infrared lamp is used as a curing lamp to maintain the temperature at 180 degrees.

[0058] After the long and short sides are oiled, fans are used to assist in cooling to speed up the curing process and prevent the paint from being uncured when the board is collected. Example

[0059] A matte chamfering method for chamfering finished plates.

[0060] Chamfer the wear-resistant layer of the plate. First, use a fixed knife to cut the wear-resistant layer on all sides of the plate to achieve a chamfer angle of 10 degrees and a chamfer width of 1.2mm. At the same time, the thickness of the product wear-resistant layer needs to be greater than or equal to 0.5mm to prevent white edges from being exposed.

[0061] Place the chamfered plate on the oiling equipment and use roller coating to achieve matte oiling of the chamfered position of the plate;

[0062] The oiled area is irradiated with infrared lamps to dry it quickly.

[0063] The oiling equipment transports the short side and long side of the plate separately. The long side slide of the equipment is used to transport the long side of the plate at a speed of 45-55m / min, and the short side slide is used to transport the short side at a speed of 15-20m / min. The infrared lamp tube is used as a curing lamp with a temperature of 180 degrees.

[0064] The above is a schematic description of the present invention and its embodiments, which is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. Therefore, if a person skilled in the art is inspired by this and, without departing from the purpose of the present invention, designs a structure and embodiment similar to this technical solution without inventiveness, they shall fall within the scope of protection of the present invention.
