Manufacturing process and application of polyvinyl chloride coiled material floor based on closed-cell foaming technology
The invention discloses a manufacturing process and application of a polyvinyl chloride coiled material floor based on a closed-cell foaming technology, and the manufacturing process comprises the following steps: (1) adding modified polyvinyl chloride, calcium-based montmorillonite, a modified reinforcing agent and an auxiliary agent into a high-speed mixing mill, maintaining for 10-30 minutes at the temperature of 110-120 DEG C, cooling to room temperature, and aging for 8-12 hours; (2) adding a product obtained in the step (1) and a composite foaming agent into a double-roller open mill for open milling into sheets, setting the temperature of double rollers to be 150-165 DEG C, and setting the time to be 5-10 minutes; and (3) adjusting the mold pressing temperature interval to 170-180 DEG C, and carrying out mold pressing foaming on a product obtained in the step (2) on a plate vulcanizing machine under the pressure of 10-15 MPa for 10-15 minutes to obtain the polyvinyl chloride coiled material floor based on the closed-cell foaming technology. According to the polyvinyl chloride coiled material floor, by using internally modified polyvinyl chloride, the material has higher mechanical strength, and by using the composite foaming agent, the temperature and the pore diameter of bubbles in the foaming process are uniform, so that excellent mechanical properties are obtained.
本发明公开了一种基于闭孔发泡技术的聚氯乙烯卷材地板的制造工艺及应用，包括以下步骤：（1）将改性聚氯乙烯、钙基蒙脱土、改性增强剂和助剂加入到高速混炼机中，在110‑120℃温度下维持10‑30分钟后，降至室温陈化8‑12小时；（2）将步骤（1）的产物和复合发泡剂加入到双辊开炼机中开炼成片，设置双辊温度为150‑165℃，时间5‑10分钟；（3）调整模压温度区间为170‑180℃，将步骤（2）的产物在平板硫化机上模压发泡10‑15分钟，压力为10‑15MPa，制得所述基于闭孔发泡技术的聚氯乙烯卷材地板。本发明的聚氯乙烯卷材地板通过使用内部改性的聚氯乙烯，使材料具有更强的力学强度，并使用复合发泡剂，使发泡过程温度、气泡孔径均匀，进而获得优异的力学性能。
