Description
技术领域 technical field
本发明涉及一种板材，具体涉及竹胶板。 The invention relates to a board, in particular to a bamboo plywood.
背景技术 Background technique
竹胶板是以竹片做主要架构和填充材料，经高压成坯的板材。竹胶板主要用于：建筑架模，车箱箱体板和箱底板，大型机械外包装板等场合。竹胶板的硬度、抗折、抗压等性能都显著强于木板，甚至在很多场合已经替代了钢模板。且竹子是易培养，成林快的林木，三到五年就可以砍伐，再生速度快。因此，国家林业部政策支持大力发展以竹为主要原材料的人造板。 Bamboo plywood is a board made of bamboo slices as the main structure and filling material, which is formed into a blank under high pressure. Bamboo plywood is mainly used in: building formwork, car box body board and box bottom board, large-scale machinery outer packaging board and other occasions. The hardness, flexural resistance, and compression resistance of bamboo plywood are significantly stronger than those of wood boards, and have even replaced steel formwork in many occasions. Moreover, bamboo is easy to cultivate and quickly grows into a forest. It can be felled in three to five years, and its regeneration speed is fast. Therefore, the policy of the Ministry of Forestry of the People's Republic of China supports the vigorous development of wood-based panels with bamboo as the main raw material.
现有竹胶板一般是多层竹帘层纵横交错排布，上下侧各一层竹席层，用胶黏剂一起热压成型。这样的竹胶板外观老旧，在车厢板、车厢底板、行李舱板等场合使用时，严重影响美观。需要在上面再铺设垫子。这样浪费成本，也很不方便，还容易褶皱，影响使用。并且竹胶板和垫子都易燃，防火性差。而现有的竹胶板或者木质压缩板的阻燃技术无一例外地都是将竹材或木材浸透阻燃药剂后获得。这样加工效率低，加工成本高。 The existing bamboo plywood is generally arranged in a criss-cross pattern with multiple layers of bamboo curtains, and each layer of bamboo mats on the upper and lower sides is hot-pressed together with an adhesive. The appearance of such bamboo plywood boards is old, and when used in occasions such as carriage boards, carriage floor boards, and luggage compartment boards, it seriously affects the appearance. A mat needs to be laid on top. This wastes cost, is also very inconvenient, and is easy to wrinkle, affecting use. Moreover, bamboo plywood and mats are flammable and have poor fire resistance. And the flame retardant technology of existing bamboo plywood or wooden compressed board all is obtained after bamboo or wood is soaked with flame retardant agent without exception. The processing efficiency is low like this, and the processing cost is high.

When the product of the present invention is used as a fireproof packaging box, side panel of a carriage, and bottom plate, because the parts exposed to the ambient air are covered in the surface layer made of fireproof boards, it can be limited in fire and flame retardancy.
附图说明 Description of drawings
图1为本发明的断面结构示意图。 Fig. 1 is a schematic cross-sectional structure diagram of the present invention.
具体实施方式 Detailed ways
如图1所示的防火竹胶板，包括基板，基板由两竹席层1、2和之 间的多个竹帘层3、3`与胶黏剂热压成型。相邻竹帘层3、3`纵横交叉布置。基板正面黏贴面层5、背面黏贴防水覆膜纸4；所述的面层5为防火板，防火板表面设置为具有凹凸的防滑面6。竹帘层3、3`由竹片经细线串联而成。具有凹凸的防滑面6也就是面层5表面具有凹凸的纹路，起到防滑作用。 The fireproof bamboo plywood as shown in Figure 1 comprises base plate, and base plate is by two bamboo mat layers 1,2 and a plurality of bamboo curtain layers 3,3 ' and adhesive thermocompression molding between. Adjacent bamboo curtain layers 3, 3' are arranged vertically and horizontally. A surface layer 5 is pasted on the front of the substrate, and a waterproof coated paper 4 is pasted on the back; the surface layer 5 is a fireproof board, and the surface of the fireproof board is set as a non-slip surface 6 with bumps. Bamboo curtain layers 3, 3' are formed by series connection of bamboo slices through thin wires. The non-slip surface 6 with concavo-convex, that is, the surface layer 5 has concavo-convex lines on the surface, which plays an anti-slip effect.
防火板又名耐火板，学名为热固性树脂浸渍纸高压层积板，有丰富的表面色彩，纹路可供选择，便于根据需求获得美化的竹胶板外观。本发明将该材料应用到竹胶板上弥补了现有竹胶板的不足。细线一般为棉线或者麻，成本低廉。细线可以将竹片连接，便于铺展、收纳，以便加工。 Fireproof board, also known as fire-resistant board, is scientifically called thermosetting resin impregnated paper high-pressure laminated board. It has rich surface colors and textures to choose from, and it is convenient to obtain a beautified appearance of bamboo plywood according to needs. The invention applies the material to the bamboo plywood to make up for the deficiency of the existing bamboo plywood. The thin thread is generally cotton thread or hemp, and the cost is low. Thin wires can connect bamboo slices, which is convenient for spreading, storage and processing.
更好是所述的竹席层1、2与竹帘层3、3`之间设置一体热压成型的天然纤维层7、8。天然纤维指的就是棉、麻、毛等纤维原料。天然纤维层7、8可以设置在上侧竹席层2处，也可以设置在下侧竹席层1处，两处设置效果更佳，能更大程度提高竹胶板强度。图1中所示就是上下两侧均设置天然纤维层7、8。竹帘层3、3`在图1的实施例中设置了九层，这样防火竹胶板产品总厚一般控制在9±0.5mm。 More preferably, natural fiber layers 7, 8 integrally formed by thermocompression are set between the bamboo mat layers 1, 2 and the bamboo curtain layers 3, 3'. Natural fibers refer to fiber raw materials such as cotton, hemp, and wool. The natural fiber layers 7 and 8 can be arranged at the upper side bamboo mat layer 2, or at the lower side bamboo mat layer 1, the effect of the two settings is better, and the strength of the bamboo plywood can be improved to a greater extent. As shown in Fig. 1, the natural fiber layers 7, 8 are arranged on the upper and lower sides. Bamboo curtain layer 3, 3 ' is provided with nine layers in the embodiment of Fig. 1, and the total thickness of fireproof bamboo plywood product is generally controlled at 9 ± 0.5mm like this.

热压固化：坯体置于通有蒸汽的空心钢模之间，利用压力机压空心钢模提供高压条件，设定压力1.55MPa，空心钢模通蒸汽加热到145℃ 下成型35min；然后保持压力，空心钢模之间通冷却水冷却10min出料即得基板； Hot press curing: the green body is placed between hollow steel molds with steam, and the hollow steel mold is pressed by a press to provide high pressure conditions. The pressure is set at 1.55MPa, and the hollow steel mold is heated to 145°C for 35 minutes by steam; then keep Pressure, cooling water between hollow steel molds to cool for 10 minutes to get the substrate;
加工面层：基板的竹席层表面用砂光机砂光定厚9±0.5mm，切割定形，然后涂胶；同时防火板表面涂胶；所用胶为环保氯丁胶；将基板与防火板胶面相对在0.5MPa下压合3h即得。 Processed surface layer: The surface of the bamboo mat layer of the substrate is sanded with a sander to determine the thickness of 9±0.5mm, cut and shaped, and then glued; at the same time, the surface of the fireproof board is glued; the glue used is environmentally friendly neoprene; the substrate and the fireproof board The rubber surface is relatively pressed at 0.5MPa for 3 hours.
产品规格：2440mm*1220mm*9mm。 Product specification: 2440mm*1220mm*9mm.
切割3块500mm*500mm*9mm的样品，检测后获得的检测结果如下表所示： Cut 3 samples of 500mm*500mm*9mm, and the test results obtained after testing are shown in the table below:
可见，增加了天然纤维层7、8的防火竹胶板结构性能显著提升。 It can be seen that the structural performance of the fireproof bamboo plywood with natural fiber layers 7 and 8 is significantly improved.
