Embodiment 1
[0012] A kind of manufacture method of self-plasticizing bamboo board, is made up of the following steps:
[0013] (1) material preparation: bamboo is pulverized into 20 purpose bamboo powder, by mass ratio m 竹粉 :m 塑化引 发剂 =100: 0.1, bamboo powder and plasticizing initiator are evenly mixed to obtain bamboo powder raw material; wherein the moisture content of bamboo powder is 20%; plasticizing initiator is made of polyvinyl alcohol, polyethylene glycol by mass ratio m 聚乙烯醇 :m 聚乙二醇 = 1:10 mixed;
[0014] (2) Self-plasticizing molding: Pave bamboo powder raw materials evenly into stainless steel molds, then start to heat up and increase the pressure. When the temperature rises to 160°C and the pressure rises to 9MPa, keep the pressure for 90 minutes, then keep the pressure and stop Heating, slowly cooling to room temperature, and releasing the pressure to obtain self-plasticized bamboo boards; wherein during paving, the paving surface of bamboo powder raw materials cannot exc...
Embodiment 2
[0016] A kind of manufacture method of self-plasticizing bamboo board, is made up of the following steps:
[0017] (1) material preparation: bamboo is crushed into 80 purpose bamboo powder, by mass ratio m 竹粉 :m 塑化引 发剂 =100: 0.2, bamboo powder and plasticizing initiator are evenly mixed to obtain bamboo powder raw material; wherein the moisture content of bamboo powder is 30%; plasticizing initiator is made of polyvinyl alcohol, polyethylene glycol by mass ratio m 聚乙烯醇 :m 聚乙二醇 = 0.5:10 mixed;
[0018] (2) Self-plasticizing molding: Pave bamboo powder raw materials evenly into stainless steel molds, then start to heat up and increase the pressure. When the temperature rises to 170°C and the pressure rises to 12MPa, keep the pressure for 30 minutes, then keep the pressure and stop Heating, slowly cooling to room temperature, and releasing the pressure to obtain self-plasticized bamboo boards; wherein during paving, the paving surface of bamboo powder raw materials cannot exc...
Embodiment 3
[0020] A kind of manufacture method of self-plasticizing bamboo board, is made up of the following steps:
[0021] (1) material preparation: bamboo is pulverized into 150 purpose bamboo powder, by mass ratio m 竹粉 :m 塑化 引发剂 =100: 0.3, bamboo powder and plasticizing initiator are evenly mixed to obtain bamboo powder raw material; wherein the moisture content of bamboo powder is 40%; plasticizing initiator is made of polyvinyl alcohol, polyethylene glycol by mass ratio m 聚乙烯醇 :m 聚乙二醇 = 0.8:10 mixed;
[0022] (2) Self-plasticizing molding: Pave bamboo powder raw materials evenly into stainless steel molds, then start to heat up and increase the pressure. When the temperature rises to 180°C and the pressure rises to 18MPa, keep the pressure for 60 minutes, then keep the pressure and stop Heating, slowly cooling to room temperature, and releasing the pressure to obtain self-plasticized bamboo boards; wherein during paving, the paving surface of bamboo powder raw materials cannot...
