具体实施方式Detailed ways
本发明建筑墙体材料用竹碎料板制造工艺是以现有的木材刨花板生产工艺为基础，以小径竹材及竹材加工剩余物为原料，通过改变胶粘剂种类及改变施胶量等工艺参数，制备出性能满足室外结构用承重板材性能要求的竹碎料板。The bamboo particleboard manufacturing process for building wall materials of the present invention is based on the existing wood particleboard production process, using small-diameter bamboo and bamboo processing residues as raw materials, and by changing the adhesive type and the process parameters such as the amount of sizing. A bamboo particle board whose performance meets the performance requirements of load-bearing boards for outdoor structures is produced.
其制备过程为：小径竹材或加工剩余物经削片机切成竹片(长度在3～5cm)，竹片经刨片机刨片后制成竹碎料(或称为竹刨花)，竹碎料经干燥，含水率控制在4％以下。干燥后的竹碎料施以一定量(施胶量应为2％～25％左右)的胶粘剂，然后铺装成型，再经热压形成板材，制成的建筑用板材密度一般为0.85～1.00g/cm3。热压温度、时间和热压压力依据竹材材料的特性和板材密度进行调整。一般热压温度为100～180℃，热压时间为1～1.5min/mm(根据材料含水率)，热压压力为1～10MPa。在热压过程中也可以采用加压冷却措施以减少板材的变形。The preparation process is as follows: small-diameter bamboo or processing residues are cut into bamboo chips (3 to 5 cm in length) by a chipper, and the bamboo chips are made into bamboo scraps (or called bamboo shavings) after being planed by a chipper. The crushed material is dried and the moisture content is controlled below 4%. Apply a certain amount of adhesive (the amount of sizing should be about 2% to 25%) to the dried bamboo scraps, then pave and shape, and then form a board by hot pressing. The density of the board made of construction is generally 0.85 to 1.00 g/cm 3 . The hot pressing temperature, time and hot pressing pressure are adjusted according to the characteristics of the bamboo material and the density of the board. Generally, the hot-pressing temperature is 100-180°C, the hot-pressing time is 1-1.5min/mm (according to the moisture content of the material), and the hot-pressing pressure is 1-10MPa. Pressurized cooling measures can also be used in the hot pressing process to reduce the deformation of the plate.
所用的胶粘剂可以酚醛粘合剂、间苯二酚粘合剂、异氰酸酯粘合剂和改性三聚氰胺粘合剂等。如用异氰酸酯胶粘剂，施胶量为2％～15％；用三聚氰胺改性脲醛胶粘剂，施胶量为5％～25％。通过改变胶粘剂种类及改变施胶量等工艺参数，制备出性能满足室外结构用承重板材各种性能要求的竹碎料板。The adhesive used can be phenolic adhesive, resorcinol adhesive, isocyanate adhesive and modified melamine adhesive, etc. If isocyanate adhesive is used, the sizing amount is 2% to 15%; if melamine-modified urea-formaldehyde adhesive is used, the sizing amount is 5% to 25%. By changing the types of adhesives and changing the amount of glue and other process parameters, the bamboo particle boards with performances meeting various performance requirements of load-bearing boards for outdoor structures were prepared.
热压后的板材再经过防腐和防霉处理，其防腐、防霉性能应能达到室外木结构建筑材料防腐、防霉性能要求，可以用于建筑或其它室外用墙体材料。After hot-pressing, the plate is treated with anti-corrosion and anti-mildew. Its anti-corrosion and anti-mildew performance should meet the anti-corrosion and anti-mildew performance requirements of outdoor wood structure building materials, and can be used for construction or other outdoor wall materials.
如图2所示，竹碎料板是由碎化处理后的碎竹材片1上施以胶层2再相互排列铺装经压制而构成的竹板，其胶层为室外用胶粘剂(如酚醛粘合剂、间苯二酚粘合剂、异氰酸酯粘合剂和改性三聚氰胺粘合剂等)制成板材，它的物理力学性能达到室外建筑结构用承重材料的性能要求。As shown in Figure 2, the bamboo particle board is a bamboo board formed by applying an adhesive layer 2 on the shredded bamboo sheet 1 and then arranging and paving each other and pressing it. The adhesive layer is an outdoor adhesive (such as phenolic Adhesives, resorcinol adhesives, isocyanate adhesives and modified melamine adhesives, etc.) are made into boards, and its physical and mechanical properties meet the performance requirements of load-bearing materials for outdoor building structures.
