一种复合塑料板材 A composite plastic sheet
本实用新型涉及建筑装饰板材，特别是一种复合塑料建筑装饰板材。 The invention relates to building decorative plates, in particular, a composite plastic construction decorative plates.
在本实用新型作出之前，塑料常用于作为建筑装饰板材，通常依其用途要求而直接成型为各种类型的板材，如ZL94205296.X公开了一种塑胶中空天花板，具有质轻、隔热、隔音、不变形，成本低的优点，但其表面装饰性不够好，色彩较单调。 Prior to the present invention, the plastic used in the construction as decorative plates, according to their use typically requires various types of directly forming sheet, such as a hollow plastic ZL94205296.X discloses a ceiling, having a light weight, heat insulation, sound insulation , no distortion, and low cost, but the decorative surface is not good enough, more monotonous color. 复合塑料板材，通常用有渗透性的纸质装饰面层与塑料芯板复合，或者以塑料装饰面层与木材或纤维板等有渗透性或多孔性材料复合构成。 The composite plastic sheet, usually permeable surface layer and the decorative paper composite plastic core, or in a decorative surface layer and plastic wood or fiberboard permeable porous material or a composite configuration. 复合板材有较好的装饰性，但纸质面层不耐用，易损坏；有渗透性的芯板加工复合时耗用较多的粘合剂，木材与纤维板易燃，防火、耐水性差。 Binders consumes a lot of the core plate when the machining of composite permeability of the wood and fiberboard flammable, fire, water resistance is poor; decorative composite sheet has good, but the surface layer of the paper is not durable, easily damaged. 这两种复合板材的应用与制造都存在一定的局限性。 Both application and manufacturing composite sheet there are some limitations.
本实用新型的目的是改进复合塑料板材，提供一种由中空塑料芯板和塑料装饰面层构成的复合塑料板材，以提高其装饰性及具有质轻、耐用，防水、耐水，隔热隔音的特点。 The object of the present invention is to improve composite plastic sheet, there is provided a composite plastic sheet constructed by a hollow plastic core and a plastic decorative surface layer, and to improve its decorative lightweight, durable, waterproof, water-resistant, heat insulation of features.
本实用新型是这样实现的，复合塑料板材由塑料芯板1、粘合剂层2和塑料装饰面层3构成。 The present invention is achieved, a composite plastic sheet 1, the adhesive layer 2 and the plastic decorative surface 3 is constituted by plastic core. 芯板是直接成型的剖面有矩形或菱形或其他形状空隙且排列有序的中空塑料板，如聚氯乙烯(PVC)塑料芯板。 Directly molding the core plate has a rectangular or rhombic cross-sectional shape or other orderly arrangement of voids and hollow plastic plate, such as polyvinylchloride (PVC) plastic core. 芯板两侧可制成互相吻合的凹凸结构，复合后的板材可以两两相互镶嵌为不同宽度的平板以适应不同用途。 Both sides of the core plate may be made uneven structure consistent with each other, the composite sheet may be a flat plate twenty-two another mosaic of different widths to accommodate different uses. 芯板上面是粘合剂层，如聚氨酯粘合剂。 The above core sheet is an adhesive layer, such as a polyurethane adhesive. 粘合剂层上面是塑料装饰面层，可采用印有花纹、图案或各种色彩的塑料薄膜，如PVC塑料薄膜，其厚度可薄至0.1～0.2mm，使用特制的设备和工艺使粘合剂薄薄而均匀地涂布在塑料薄膜面层的背面并平整而牢固地粘贴到芯板表面，可以单面粘贴，也可以粘贴于芯板两个表面，视需要而定。 The above adhesive layer is a plastic decorative surface layer, can be printed with patterns, color patterns or various plastic films such as PVC plastic film having a thickness as thin as 0.1 ~ 0.2mm, the use of special equipment and technology so that the adhesive agent thinly and uniformly coated on the back surface of the plastic film layer is flat and firmly adhered to the surface of the core plate, one surface can be attached, it may be attached to both surfaces of the core sheet, as required. 粘贴后的薄膜面层与芯板连为一体，不发生变形或任何被溶剂侵蚀的现象。 Film surface layer and the core plate pasting a single entity, any deformation or erosion phenomena solvent occurs. 复合后的塑料板材的长度可视需要而裁定。 After the composite plastic sheet length determination visual needs.
这样复合而成的复合塑料板材，表面平整美观，装饰性好，色彩与图案花纹容易变换，而且质轻、耐用，防水、耐水，隔热、隔音性能好，可视需要而镶嵌成不同规格的平板，使用方便，如采用阻燃塑料制成复合板材更具有阻燃性能。 Such composite made of a composite plastic sheet, the surface smooth and beautiful, decorative, easy to change colors and design patterns, and light weight, durable, waterproof, water resistance, heat insulation, sound insulation, while optionally set into different specifications flat, easy to use, as flame-retardant plastic composite sheet made more flame retardant properties. 复合塑料板材可用作室内天花板，隔墙或家具等，用途广泛，是一种新型的建筑装饰板材。 Composite plastic sheet can be used as other indoor ceiling, wall or furniture, widely used, is a new building decorative plates.
图面说明：附图是本实用新型(单面)复合塑料板材剖面图，1是塑料芯板，2是粘合剂层，3是塑料装饰面层。 Drawing Description: The present invention drawings are (single-sided) cross-sectional view of the plastic composite sheet, a plastic core 1, 2 is an adhesive layer, 3 is a plastic decorative surface.
下面结合附图对本实用新型的实施例进行描述，如附图所示，塑料芯板1是采用防火性能好的PVC塑料经挤塑直接成型的剖面有矩形空隙且排列整齐的中空板，芯板两侧制成可以互相镶嵌的凹凸结构。 In conjunction with the accompanying drawings of embodiments of the present invention will be described, as shown in the drawings, plastic core 1 is made of fireproof PVC plastic good performance by direct extrusion gap shaped cross section and a rectangular hollow plate neat, core plate concavo-convex structure may be formed on both sides of each mosaic. 粘合剂层2是聚氨酯粘合剂，均匀地涂布于PVC塑料薄膜面层3的背面并平整而紧密地粘贴在芯板表面上，三者牢固结合构成复合PVC塑料板材。 2 is a pressure-sensitive adhesive layer of a polyurethane adhesive, to the back surface uniformly coated PVC plastic film layer 3 and the surface smooth and tightly attached to the surface of the core plate, the three strongly bonded composite composed of PVC plastic sheet. 复合后的板材可视用途镶嵌成不同规格的平板，用作室内天花板、隔墙或家具等，装饰性好并具有质轻、耐用、防水、防火和隔音的优点。 After the composite sheet visualization purposes set into a plate of different specifications, used as an interior ceiling, wall or furniture, decorative and good lightweight, durable, waterproof, fireproof and soundproof advantages.
