[0002] The traditional facing fireproof board in the market is actually a kind of artificial board, which is mainly made of kraft paper, not wood as many people think. The production of ordinary fireproof board is made of surface colored paper and multiple layers of high-grade kraft paper, which are impregnated with resin glue and pressed at high temperature. Impregnation of multiple layers of kraft paper can easily lead to problems such as poor permeability, poor weather resistance, easy deformation, short service life and high cost of kraft paper.

[0003] Based on the demand for environmental protection, flexibility and functionality of fireproof board materials, new materials and application technologies of formaldehyde-free flexible functional fireproof boards are developed. Relatively low-priced water-based polymer raw materials are selected to construct a directional regulation of the molecular weight of water-based polymers and an enhanced toughening group introduction mechanism to achieve adjustable viscosity and enhanced toughness of the impregnated resin, and overcome the difficulties of high cost, poor permeability and high brittleness of formaldehyde-free impregnated resins. At the same time, the panel decorative paper bonding and fixing operation during the preparation of fireproof boards, because the panel decorative paper cutting and board surface conveying are not on the same production line, leads to a decrease in the bonding efficiency of the two, affecting the subsequent hot pressing process of the board;

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] See also Figure 1-7 , the present invention provides a technical solution:

[0033] Example 1: Study the optimization of the impregnation process of formaldehyde-free impregnation resin and wood fiber, and innovate the layer-by-layer self-assembly and supramolecular chemical technology to preferentially impregnate and fill the small molecule high permeability resin into the cell wall and cell cavity of the wood fiber for cross-linking, and then impregnate or coat the macromolecular flexible resin to improve the flexibility, so as to achieve the strengthening, toughening and self-bonding properties of the impregnated wood fiber;

[0034] like Figure 1 As shown, the method for preparing decorative panels by laminating fire-resistant impregnated plant fibers includes independent impregnation treatment and laminating operation, the plant fiber board is in contact with the phenolic resin glue, an independent immersion chamber is provided, the plant fiber board is vertically placed in the chamber filled with the phenolic resin glue, wherein the ratio of the phenolic resin glue to the plant fiber board is controlled at 1:2, and at the same time, the panel decorative paper is dipped into melamine glue by a laminating mechanism and then laid flat on the impregnated plant fiber board, thereby completing the laminating of the plant fiber board and the panel decorative paper;

[0035] Then, the hot pressing plate mechanism is used to move the fully bonded plant fiber decorative panels one by one into the interlayer of the hot pressing plate mechanism, until all the interlayers of the hot pressing plate mechanism are placed with the plant fiber decorative panels, and the temperature is gradually increased while pressing, and finally the hot pressing temperature of the plant fiber decorative panels is stabilized at 120°C, and the total hot pressing time is controlled at 40 minutes. After the hot pressing is completed, the plate surface of the hot pressing plate mechanism is cooled down, and the plant fiber decorative panels in the hot pressing plate mechanism are taken out after the temperature is controlled to 30°C, and then the plant fiber decorative panels are trimmed and polished;

[0036] A low-density, highly absorbent plant fiber density board is selected, and through the process of impregnating phenolic resin glue, heating, rolling, cooling and other processes, a fireproof board with good fireproof, moisture-proof, oil-proof, anti-static, weather-resistant, corrosion-resistant and non-deformable properties is obtained. Compared with the fireproof board made of surface colored paper and multiple layers of high-grade kraft paper impregnated with resin glue and pressed at high temperature, the plant fiber decorative board is more resilient, more impact-resistant and more durable.

[0037] Embodiment 2: Considering the panel decorative paper laminating work in the preparation process of the plant fiber decorative board, the plant fiber board is evenly moved to the transmission roller group 3 in the transmission frame 2 through the movable clamping arm after being dipped in glue, such as Figure 2 As shown, a cross slide 1 9 and a cross slide 2 10 are fixed on the base 1. The cross slide 1 9 and the cross slide 2 10 are placed alternately. At the same time, a slide groove 11 is opened on the cross slide 1 9 and the cross slide 2 10. The slide groove 11 is cross-shaped as a whole. Figure 4 As shown, a slider 12 is slidably connected in the slide grooves 11 on both sides, a locking rod 15 is movably sleeved and connected to the two sliders 12 on the cross slide 1 9 and the cross slide 2 10, and a transmission gear 1 16 is fixedly connected to one side of the locking rod 15;

[0038] A motor 17 is installed on the top of the base 1, and a rotating shaft 18 is fixed on the output end of the motor 17. Two pulleys 19 are sleeved and fixed on the rotating shaft 18. A pulley 20 is also movably connected to the base 1 outside the cross slide 19 and the cross slide 20. The pulley 20 is connected to the pulley 19 through a sleeve belt, so that the transmission tooth 21 connected to the pulley 20 on the side of the cross slide 19 and the cross slide 20 10 can rotate synchronously through the rotation of the motor 17;

[0039] The transmission tooth 21 is meshed with the transmission tooth 16, so the active rotation of the transmission tooth 21 drives the transmission tooth 16 on the lock rod 15 to perform planetary motion. Figure 3 As shown, when the transmission gear 21 rotates clockwise, the transmission gear 16 drives the lock rod 15 to rotate clockwise synchronously, and the slider 12 connected to the right end of the lock rod 15 continues to move rightward, while the slider 12 connected to the left end of the lock rod 15 starts to move downward. At this time, the plate placing table 13 and the material clamping table 14 movably connected to the side of the slider 12 tend to be synchronously horizontal on the middle side of the cross slide 1 9 and the cross slide 2 10;

[0040] The cross slide 1 9 and the cross slide 2 10 are staggered, so that the connection points of the slider 12 on the cross slide 1 9 and the cross slide 2 10 are separated from the board placement table 13 and the clamping table 14, thereby ensuring that the slider 12 moves on the cross slide 1 9 and the cross slide 2 10, and the board placement table 13 and the clamping table 14 are always kept horizontally placed, which is conducive to the subsequent placement and movement of the plant fiber board;

[0041] It involves the specific lamination work of plant fiberboard and panel decorative paper, such as Figure 3 As shown, the transmission gear 21 on the side of the cross slide 19 rotates to realize the clockwise rotation of the transmission gear 16 on the lock rod 15. At the same time, the clamping platform 14 connected to the slider 12 at the front end of the lock rod 15 moves to the rightmost side, and the board placing platform 13 is flush with the clamping platform 14 and has a tendency to start moving downward. At this time, the clamping platform 14 obtains the panel decorative paper;

[0042] like Figure 2 As shown, since melamine glue is applied on both sides of the panel decorative paper, a rubber roller 6 is first installed on the fixing frame 4 at the top of the transmission frame 2, and the surface of the rubber roller 6 is covered with melamine glue using the rubber box 1 5 and the rubber box 2 7, wherein the rubber box 2 7 located at the top continuously pours melamine glue onto the surface of the rubber roller 6, and continuously applies melamine glue to the top of the panel decorative paper through the rotation of the rubber roller 6, and the rubber box 1 5 located at the bottom of the panel decorative paper immerses the bottom rubber roller 6, and the coating work on the bottom surface of the panel decorative paper can also be completed with the rotation of the rubber roller 6;

[0043] A locking frame 8 is also installed on the top of the transmission frame 2. The locking frame 8 completes the locking and releasing work of the panel decorative paper through rollers, which facilitates the subsequent clamping platform 14 to clamp the panel decorative paper.

[0044] As the clamping table 14 moves to the rightmost side, Figure 5 As shown, at this time, the cylinder 22 symmetrically arranged on the clamping platform 14 pushes the clamp 23 to close, completing the acquisition of the decorative paper of the side panel of the locking frame 8, and at this time, the clamping platform 14 starts to move to the leftmost side, pulling the panel decorative paper to unfold in the cross slide 1 9 and the cross slide 2 10, and at this time, the board placing platform 13 moves downward to start acquiring the impregnated plant fiber board, and a transmission roller group 3 is arranged in the transmission frame 2, so that the impregnated plant fiber board is sent into the transmission frame 2 by a mechanical arm, and the transmission roller group 3 moves to the top of the glue discharge hole 24 of the board placing platform 13, and the entire board placing platform 13 is set accordingly according to the size of the plant fiber board area;

[0045] Then, when the clamping table 14 drags the panel decorative paper to the leftmost position of the cross slide 1 9 and the cross slide 2 10, the board placing table 13 carrying the plant fiber board upward is flush with the clamping table 14. At this time, the plant fiber board is attached to the bottom of the panel decorative paper, and the motor 17 stops rotating the pulley 19. At this time, the plant fiber board and the panel decorative paper are attached and fixed, and the excess panel decorative paper needs to be cut;

[0046] like Figure 6As shown, a slideway 25 is provided on one side of the board placement platform 13, and a sliding cutter head 26 is slidably connected inside the slideway 25 and on the placement platform. Under normal conditions, the sliding cutter head 26 is located inside the slideway 25, and the sliding cutter head 26 is telescopically arranged. After the panel decorative paper is covered on the plant fiber board, the battery-driven motor 17 at the bottom of the board placement platform 13 is used to drive the screw rod to rotate, synchronously drive the sliding cutter head 26 in the slideway 25 to move, and automatically extend after leaving the slideway 25, and the sliding cutter head 26 abuts against the right panel decorative paper to complete the cutting work. Due to the coating of the adhesive on the panel decorative paper and the plant fiber board, no relative movement occurs during the fitting and cutting, causing the panel decorative paper on the plant fiber board to be misaligned.

[0047] The cutting time of the panel decorative paper on the plant fiber board and the fixing time of each position of the board placement platform 13 and the clamping platform 14 are set, and then after the cutting of the panel decorative paper is completed, the cylinder 22 on the clamping platform 14 is controlled to contract, and the clamp 23 is pulled away from the fixation of the other side of the panel decorative paper, and then the transmission gear 21 continues to rotate, driving the plant fiber board placed on the board placement platform 13 and the panel decorative paper to move upward;

[0048] like Figure 3 As shown, a top plate 27 is fixedly connected to the top of the cross slide 1 9 and the cross slide 2 10, and a conveying mechanism 28 is slidably connected to the middle side slide rail of the top plate 27. Clamping arms that can open and close are arranged on both sides of the conveying mechanism 28. After the cutting of the panel decorative paper on the entire plate placing platform 13 is completed, the conveying mechanism 28 arrives at the top of the plate placing platform 13 in advance, and then the plate placing platform 13 is lifted to move the plant fiber decorative board to the bottom of the conveying mechanism 28. As the conveying mechanism 28 completes the clamping and fixing of the plant fiber decorative board, the plate placing platform 13 moves downward and the clamping platform 14 moves to the right, and then the two are flush at the middle intersection. At this time, the clamp 23 on one side of the clamping platform 14 contacts the panel device paper on the locking frame 8, and the glued panel decorative paper is obtained again, and the conveying mechanism 28 moves the semi-finished plant fiber decorative board to the hot pressing equipment one by one. After continuous hot pressing at 120°C and 40 minutes, the forming of the plant fiber decorative board is completed;

[0049] With the longitudinal movement of the board placement table 13 and the lateral movement of the clamping table 14, the panel decorative paper and the plant fiber board are continuously brought into contact and fit, and the raw material transmission on the transmission frame 2 and the transfer of the formed plant fiber decorative board by the handling mechanism 28 are coordinated to realize the complete high-speed automatic bonding of the plant fiber board and the panel decorative paper.

[0050] Working principle of the present invention: Plant fiber decorative board raw material preparation, density 600-800kg / m 3 The plant fiberboards are immersed in phenolic resin glue and then fed one by one into the transmission roller group 3 on the transmission frame 2;

[0051] Pull out one side of the panel decoration paper tube, pass it through the rubber roller 6 in turn and lock it on the locking roller, and feed the melamine glue into the glue box 1 5 and the glue box 2 7 respectively, start the motor 17 to drive the rubber roller 6 to rotate, so that the upper and lower rubber rollers 6 are attached to the surface of the melamine glue, so that the panel decoration paper moving between the rubber rollers 6 is coated with the melamine glue;

[0052] The motor 17 on the base 1 is started, and the rotation of the motor 17 drives the cross slide 1 9 and the side transmission gear 21 of the cross slide 2 10 to rotate. After one side of the clamping platform 14 contacts the panel decorative paper on the locking frame 8, it starts to move to the left, and at this time, the board placing platform 13 moves downward to one side of the transmission frame 2, and the transmission roller group 3 moves the plant fiber board to the board placing platform 13. Subsequently, the clamping platform 14 drives the panel decorative paper to cover the top of the board placing platform 13. With the rise of the board placing platform 13, the top of the plant fiber board fits with the bottom of the panel decorative paper, and the cutting of the panel decorative paper is completed by sliding the sliding cutter head 26. When the board placing platform 13 moves upward, the clamp 23 disengages from the clamping of the other side of the panel decorative paper, and the plant fiber decorative board is pushed into the top transport mechanism 28 by the board placing platform 13.

[0053] The transport mechanism 28 continuously moves the semi-finished plant fiber decorative panels to the roller pressing device for stabilization, and then sends them into the hot pressing device one by one. After uniform hot pressing at 120°C and 40 minutes, the plant fiber decorative panels in the hot press are taken out and trimmed and polished.
