Description

Modified polyolefin / polyester board and its manufacturing method Technical Field

[0001] This invention relates to the field of polymer sheet technology, and in particular to a modified polyolefin / polyester sheet and its manufacturing method. Background Technology

[0002] Sustainable development of resources refers to a development model that ensures future generations can continue to utilize resources while meeting current human needs. The treatment and reuse of waste materials is an effective way to achieve sustainable development. The treatment and reuse of waste polymer materials has received widespread attention in the industry, as it not only reduces environmental damage and material waste but also offers significant economic benefits.

[0003] Products such as wind turbine blades and plastic bottles, which are made of polymer composite materials such as polyolefins / polyesters, will be subject to large-scale disposal in the present or near future. Some of these products are difficult to recycle due to the presence of other composite materials. The current disposal method is to send them to landfills, which cannot achieve sustainable resource utilization.

[0004] Manufacturing sheets is one way to reuse polymer composites such as polyolefins and polyesters. To improve the flexural modulus, hardness, toughness, fatigue resistance, and glass transition temperature of the sheets, calcium carbonate is added to the polyolefins and polyesters. Furthermore, increasing the amount of calcium carbonate added reduces the manufacturing cost of the sheets. In existing technologies, due to the small intermolecular contact area and low compatibility between polymers and calcium carbonate, the amount of calcium carbonate added to polyolefins and polyesters is relatively low. Generally, the amount of calcium carbonate added per 100g of polyolefin or polyester does not exceed 250g; otherwise, the product performance will drop sharply, calcium carbonate will precipitate on the product surface, resulting in numerous small pits and severely affecting the product's appearance. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a modified polyolefin / polyester board with excellent performance and its manufacturing method.

[0006] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows:

[0007] A modified polyolefin / polyester board includes a polyester / polyolefin substrate and a composite layer laminated on one or both sides of the polyester / polyolefin substrate. The polyester / polyolefin substrate is obtained by continuous mixing and plasticizing and two-stage extrusion. The polyester / polyolefin substrate is a solid layer or a foamed layer.

[0008] Furthermore, the composite layer includes a UV coating, a wear-resistant layer, a patterned film layer, and a sound-absorbing pad layer. The modified polyolefin / polyester board is formed by roll-pressing a wear-resistant layer, a patterned film layer, and a sound-absorbing pad onto a polyester / polyolefin substrate board, followed by roll-coating with UV paint and photocuring to form a UV coating. The board is then cut, grooved, and packaged. The surface of the modified polyolefin / polyester board body contains simulated three-dimensional textures.

[0009] Furthermore, the composite layer includes melamine patterned wear-resistant paper, melamine balance paper, adhesive, and a sound-absorbing pad layer. The modified polyolefin / polyester board is formed by simultaneously hot-pressing melamine patterned wear-resistant paper and melamine balance paper onto the upper and lower surfaces of a polyester / polyolefin substrate, and then rolling-coating the adhesive to adhere the sound-absorbing pad layer. The surface of the modified polyolefin / polyester board body contains simulated three-dimensional textures.

[0010] Furthermore, the foamed layer is formed by adding 0.5-3 parts of chemical foaming agent to the solid layer components and extruding and foaming, or by physically foaming by introducing a certain amount of carbon dioxide or nitrogen gas during the extrusion of the solid layer components.

[0011] Furthermore, the solid layer is modified using one or more of the following methods: grafting modification, blending modification, coupling / crosslinking modification, and fiber reinforcement modification.

[0012] Furthermore, the solid layer is grafted and modified, and the specific components and weight parts are as follows:

[0034] 5-20 parts of rubber or elastomer

[0035] Calcium carbonate 50-500 parts

[0036] 10-20 parts flame retardant.

[0037] Furthermore, the polyolefin / polyester is one or more of PE, PP, PB, PET, and PETG, and is either recycled or virgin material; the rubber or elastomer is one or more of SBS, TPE, TPU, EPDM, NBR, and EVA; and the fiber is one or more of plant fiber, inorganic fiber, and chemical fiber.

[0038] Furthermore, the two-stage extrusion involves using two extruders in succession for extrusion. The materials are mixed according to their mass components and then extruded in a first-stage reactive extruder, followed by extrusion in a second-stage twin-screw extruder.

[0039] Furthermore, the sound-absorbing pad layer is formed by rolling and bonding a sound-absorbing pad under a polyester / polyolefin substrate.

[0040] A method for manufacturing a modified polyolefin / polyester board, wherein the substrate board is a solid layer or a foamed layer, and single or multiple modifications are selected, comprising the following steps: weighing and mixing the required raw materials and adding them to a mixing unit for mixing and plasticizing; the mixing unit first hot-mixing to 120℃-140℃, then discharging the material into a cold-mixing unit for cooling and mixing to 50℃, and then adding it to a two-stage extrusion unit; the first-stage reactive extruder first reacts and modifies the material at 180℃-240℃, and the second-stage extruder extrudes the material into a die at 160℃-220℃, and then the material enters a roll forming machine at 160℃-200℃, where it first rolls and presses a composite patterned film layer and a wear-resistant layer, and then rolls and presses a composite sound-absorbing pad at 80℃-100℃; cooling, shaping, and cutting to form a large polyolefin / polyester board; the wear-resistant layer of the large polyolefin / polyester board is coated with a UV coating and cured to form a UV coating; and the board is then cut, grooved, and packaged to form the polyolefin / polyester board.

[0041] A method for manufacturing a modified polyolefin / polyester board, wherein the substrate board is a solid layer or a foamed layer, and single or multiple modifications are selected, comprising the following steps: weighing and mixing the required raw materials and adding them to a mixing unit for mixing and plasticizing; the mixing unit first hot-mixing to 120℃-140℃, then discharging the material into a cold-mixing unit for cooling and mixing to 50℃, and then adding it to a two-stage extrusion unit; the first-stage reactive extruder first reacts and modifies the material at 180℃-240℃, and the second-stage extruder at 160℃-220℃. After being extruded and formed under certain conditions, the material enters a roll forming machine and is rolled to a certain thickness at 160℃-200℃. After cooling and cutting, a polyolefin / polyester substrate board is formed. Under the conditions of pressure 3-18Mpa, temperature 150-220℃, and time 30-600s, melamine patterned wear-resistant paper and melamine balance paper are simultaneously hot-pressed onto the upper and lower parts of the polyolefin / polyester substrate board. Adhesive is then applied to the board to bond a sound-absorbing pad. The board is then cut, grooved, and packaged to form the polyolefin / polyester board.

[0042] The mixed plasticizing two-stage extrusion method used in this application involves connecting a high-low temperature mixing unit to a two-stage extruder. First, the high-low temperature mixing unit performs the mixing and plasticizing, followed by two-stage extrusion, forming a continuous manufacturing method. This method, by separating the extrusion process, allows the pre-extrusion and main extrusion stages to be performed simultaneously, thus significantly shortening the production cycle. Furthermore, the pretreatment process can be automated, reducing the workload of operators and improving production efficiency. Continuous mixed plasticizing is used to achieve the mixed pre-plasticization of graft-modified, blend-modified, coupling / crosslinked modified, and fiber-reinforced modified materials for further modification. Two-stage extrusion and roller pressing are used to link graft modification, blend modification, coupling / crosslinked modification, and fiber-reinforced modification. Two-stage extrusion allows for multiple modifications to be performed simultaneously.

[0043] Among these methods, grafting modification involves the following steps: Grafting modification: Under the action of an initiator, the macromolecular chains of polyolefins and polyesters undergo chain breakage during bi-stage extrusion shearing, resulting in a decrease in molecular weight and a wider molecular distribution. Simultaneously, maleic anhydride is grafted onto the polyolefin and polyester molecular chains, improving the material's polarity, enhancing intermolecular interactions, better encapsulating calcium carbonate, increasing calcium carbonate filler content, and reducing costs. Blending modification: Through mixing, dispersion, and bi-stage extrusion shearing, multiple materials undergo continuous molecular cross-linking and interpenetration, forming a denser molecular network. This combines the advantages of multiple materials, overcoming the disadvantages of a single material, and leveraging the properties of multiple materials to improve the product's impact strength, rigidity, and toughness, while increasing calcium carbonate filler content and reducing costs. Coupling / crosslinking modification: Under the action of coupling or crosslinking agents, through mixing, dispersion, and bi-stage extrusion shearing plasticizing, the molecular chains react and form a three-dimensional network structure through chemical bonds. This results in a larger contact area between molecules, improving compatibility with calcium carbonate, increasing calcium carbonate filler content, and reducing costs. Coupling and crosslinking also improve the product's flexural modulus, hardness, and glass transition temperature. Fiber reinforcement modification: The fiber surface has a layer of functional groups such as oxides, hydroxyl groups or amino groups. Through mixing, dispersion and two-stage extrusion shear plasticizing, it can combine with the active functional groups in polyester and polyolefin to form strong chemical bonds, thereby improving its strength and stiffness. The fiber can inhibit the fracture of polyolefin and polyester materials. When external force is applied, the fiber can absorb and disperse stress, hinder the propagation of cracks, and improve toughness and fatigue resistance.

[0044] Compared with existing technologies, the advantages of this invention are as follows: The manufacturing process of this invention is a continuous, synchronous composite molding process involving mixed plasticizing and two-stage extrusion. No downtime is required between each step, thus enabling 24-hour uninterrupted production with high efficiency. Continuous production allows for precise control and online monitoring, ensuring product quality stability and consistency; it also reduces waste of raw materials and energy, lowering production costs. The material flowability is better, and the venting effect is improved; this helps avoid problems such as bubbles and product surface defects, improving product quality and reducing the defect rate.
