Description

Technical Field

[0001] This invention relates to the field of wood composite material production technology, and in particular to a device for UV-resistant enhancement treatment of wood composite materials. Background Technology

[0002] Wood composite materials are widely used in construction, furniture, and decoration due to their advantages such as environmental friendliness, renewability, and good mechanical properties. However, during long-term outdoor use, wood composite materials are susceptible to aging due to ultraviolet (UV) radiation, resulting in surface fading, cracking, powdering, decreased mechanical properties, and shortened service life. Therefore, UV-resistant treatment is necessary for wood composite materials. Currently, most devices on the market for UV-resistant treatment of wood composite materials use an impregnation method. This involves immersing the wood composite material in a UV-resistant modifier, allowing the modifier to adhere to the surface and interior of the material, thereby achieving a UV-resistant enhancement effect. These devices typically include an impregnation tank, a load-bearing structure, and simple heating components to complete the basic impregnation and heating operations.

[0003] Existing UV-resistant treatment devices have many drawbacks and problems. First, most devices lack an effective modifier circulation and delivery mechanism, leading to uneven temperature and concentration of the modifier in the impregnation tank. This results in inconsistent impregnation effects across different parts of the wood composite material, affecting the quality of the UV-resistant treatment. Second, the supporting structure is mostly fixed, leaving the wood composite material in a static state during impregnation. This insufficient contact with the modifier leads to incomplete impregnation in certain areas, preventing the modifier from fully exerting its effect. Third, some devices have poor sealing performance, making it prone to modifier leakage during treatment. This not only causes waste but also affects the stability of the treatment environment. Furthermore, the lack of effective temperature and pressure monitoring and control mechanisms makes it difficult to ensure the stability of the treatment process. In addition, existing devices have not achieved synergistic optimization between the modifier's action and the device structure, resulting in a short duration of UV-resistant effect, which cannot meet the requirements for long-term outdoor use of wood composite materials. Therefore, we propose a UV-resistant enhancement treatment device for wood composite materials to solve this problem. Summary of the Invention

[0010] Preferably, guide rods are fixedly installed at the four bottom corners of the top cover, and guide frames are fixedly installed on both sides of the impregnation tank, with the guide frames slidably sleeved on the outer side of the corresponding guide rods.

[0011] Preferably, the UV-resistant modifier is composed of the following components by mass fraction: 0.5%-1.5% UV absorber, 0.8%-2.0% free radical scavenger, 30%-40% low molecular weight phenolic resin, and the remainder being distilled water; the UV absorber is an o-hydroxybenzophenone or benzotriazole, which can strongly absorb high-energy UV light and convert it into heat energy for release, thus preventing UV light from damaging the wood composite material; the free radical scavenger is a hindered amine light stabilizer, which can capture the active free radicals generated by the wood composite material under UV irradiation, inhibit photo-oxidation reaction, and further enhance the UV resistance effect; the low molecular weight phenolic resin can enhance the bonding force between the modifier and the wood composite material, while improving the water resistance and mechanical properties of the material, and extending the duration of the UV resistance effect.

[0012] The beneficial effects of this invention are as follows: 1. The UV-resistant enhancement treatment device for wood composite materials described in this invention utilizes a circulating conveying and heating mechanism. A rotary motor drives a drive shaft, eccentric wheel, sliding plate, and piston plate in coordinated motion. This, along with left and right partitions and a one-way valve, ensures stable circulating delivery of the UV-resistant modifier. Simultaneously, a heater heats the modifier, and multiple temperature sensors on the inner wall of the impregnation tank monitor the temperature in real time. When temperature deviations occur, the rotational speed of the rotary motor can be increased to improve circulation efficiency, ensuring uniform and stable temperature of the modifier. This provides a suitable temperature environment for the UV-resistant treatment of wood composite materials, effectively improving the stability and controllability of the treatment process, ensuring consistent treatment results, avoiding differences in treatment effects due to uneven temperature, and further enhancing the overall quality of the UV-resistant treatment of wood composite materials.

[0013] 2. In this invention, the UV-resistant enhancement treatment device for wood composite materials, by setting up a bearing mechanism and a driving mechanism to work together, the driving mechanism drives the rotating shaft, turntable, round rod and connecting rod to move, thereby driving the connecting plate to rotate back and forth, causing the bearing frame and the wood composite material inside to swing left and right, breaking the limitations of traditional static impregnation, significantly improving the contact uniformity between the wood composite material and the UV-resistant modifier, so that all parts of the wood composite material can fully contact and impregnate the modifier, avoiding the problem of insufficient impregnation in some areas, ensuring that the modifier can be evenly attached to the surface and interior of the wood composite material, effectively enhancing the UV resistance of the wood composite material, extending the service life of the material, and improving the quality of the treated material.

[0014] 3. In this invention, the UV-resistant treatment device for wood composite materials is equipped with a lifting mechanism and a sealing plate. The lifting mechanism drives the top cover to rise and fall smoothly, which facilitates the placement and removal of wood composite materials. During the treatment process, the sealing plate effectively seals the impregnation tank. The pressure gauge monitors the pressure in the impregnation tank in real time, preventing the modification agent from leaking and the entry of external impurities. At the same time, it ensures the stability of the impregnation environment, reduces the waste of modification agent, and lowers the treatment cost. In addition, the sealing structure can work with the circulating conveying heating mechanism to maintain the temperature and pressure stability in the impregnation tank, further optimizing the treatment effect and ensuring the smooth progress of the UV-resistant treatment.

[0015] 4. In this invention, the UV-resistant enhancement treatment device for wood composite materials, through the reasonable combination of UV-resistant modifier components and the overall structural design of the device, enables the modifier to fully exert its function. The UV absorber can absorb high-energy UV light and convert it into heat energy for release. The free radical scavenger can capture the active free radicals generated by the material under UV irradiation and inhibit photo-oxidation reaction. The low-molecular-weight phenolic resin enhances the bonding force between the modifier and the wood composite material, improves the water resistance and mechanical properties of the material. Combined with the device's circulation conveying, uniform impregnation and temperature control functions, it achieves comprehensive UV-resistant enhancement treatment of wood composite materials, effectively improves the UV resistance of wood composite materials, extends the duration of the UV resistance effect, and improves the practicality and durability of the material.

[0023] In this embodiment, the lifting mechanism 3 includes an electric push rod 302, a base plate 301, and a side plate 303.

[0025] In this embodiment, the UV-resistant modifier is composed of the following components by mass fraction: 0.5%-1.5% UV absorber, 0.8%-2.0% free radical scavenger, 30%-40% low molecular weight phenolic resin, and the remainder is distilled water. The UV absorber is an o-hydroxybenzophenone or benzotriazole, which can strongly absorb high-energy UV light and convert it into heat energy, thus preventing UV light from damaging the wood composite material. The free radical scavenger is a hindered amine light stabilizer, which can capture the active free radicals generated by the wood composite material under UV irradiation, inhibit photo-oxidation reaction, and further improve the UV resistance effect. The low molecular weight phenolic resin can enhance the bonding force between the modifier and the wood composite material, while improving the water resistance and mechanical properties of the material, and extending the duration of the UV resistance effect.

[0026] In this embodiment, during use, the lifting mechanism 3 first controls the top cover 2 to rise. The electric push rod 302 in the lifting mechanism 3 pushes the side plate 303 to move the top cover 2 upward. The guide rod 201 at the bottom of the top cover 2 slides in the guide frame 202 to ensure that the top cover 2 rises and falls smoothly. Then, the wood composite material is placed in the support frame 501 of the support mechanism 5. Next, an anti-ultraviolet modifier composed of ultraviolet absorber, free radical scavenger, low molecular weight phenolic resin and distilled water in corresponding mass fractions is filled into the impregnation tank 1. Then, the lifting mechanism 3 controls the top cover 2 to descend, so that the sealing plate 502 of the support mechanism 5 presses against the impregnation tank 1. The sealing and pressure gauge 8 monitors the pressure status in the impregnation tank 1 in real time. The controller 7 coordinates the start-up and operation of each mechanism. After the circulation conveying heating mechanism 4 is started, the rotary motor 412 drives the drive shaft 411 to rotate. The drive shaft 411 drives the eccentric wheel 410 to rotate. The eccentric wheel 410 drives the slide plate 409 to slide in the square hole of the piston plate 408, thereby driving the piston plate 408 to move up and down between the left partition 404 and the right partition 405. With the cooperation of the one-way valve 407 in the top and bottom through holes on one side of the left partition 404 and the right partition 405, the circulation conveying of the UV modifier is realized. The one-way valve 407, through the valve body 40702, The cooperation of the housing 40701 and the compression spring 40703 ensures unidirectional flow of the modifier. During the conveying process, the heater 406 heats the modifier. Multiple temperature sensors 9 on the inner wall of the impregnation tank 1 monitor the temperature of the modifier in real time. When a large temperature deviation is detected, the rotary motor 412 accelerates its rotation to speed up the circulation and conveying of the modifier, ensuring uniform temperature of the modifier. At the same time, the drive mechanism 6 is activated. The drive motor 601 drives the vertical shaft 602 to rotate, which in turn drives the worm gear 603 to rotate. The worm gear 603 meshes with the worm wheel 604, driving the rotating shaft 605 to rotate. The rotating shaft 605 drives two turntables 606 to rotate. The round rod 607 on the 6 drives the connecting rod 608 to move, and the connecting rod 608 drives the connecting plate 503 to rotate back and forth. The connecting plate 503 then drives the support frame 501 and the wood composite material inside to swing left and right, thereby improving the uniformity of contact between the wood composite material and the anti-UV modifier, so that the wood composite material can be fully impregnated in the anti-UV modifier, and finally achieve the anti-UV enhancement treatment of the wood composite material, effectively avoiding damage to the wood composite material by ultraviolet light, inhibiting photo-oxidation reaction, enhancing the bonding force between the modifier and the wood composite material, improving the water resistance and mechanical properties of the material, and extending the duration of the anti-UV effect.
