The invention relates to a preparation method of a low-odor and low-VOC (volatile organic compound) composite skin, and mainly solves the problems of strong odor and high VOC of a composite skin for automotive trim in the prior art. The preparation method of the low-odor and low-VOC composite skin comprises the following steps: 1) fuel gas and air are dried and then enter a fuel gas buffer tank and an air buffer tank respectively; (2) the fuel gas discharged from the fuel gas buffer tank enters a mixer after being subjected to pressure control; (3) the air discharged from the air buffer tank enters a mixer after being subjected to pressure control; (4) controlling the flow of the fuel gas and the air to adjust the volume ratio of the fuel gas to the air in the mixer to obtain uniform mixed gas; 5) feeding the mixed gas into a gas purification device filled with a molecular sieve adsorbent to obtain purified mixed gas; and (6) the purified mixed gas enters a flame compounding machine for flame compounding, and the low-odor low-VOC composite skin is obtained, the problem is well solved, and the method can be used for industrial production of the automobile interior composite skin.
本发明涉及一种低气味低VOC复合表皮的制备方法,主要解决现有技术中汽车内饰用复合表皮气味大、VOC高的问题。本发明通过采用一种低气味低VOC复合表皮的制备方法,包括以下步骤:1)燃气和空气经干燥后分别进入燃气缓冲罐、空气缓冲罐;2)从燃气缓冲罐中出来的燃气经压力控制后进入混合器;3)从空气缓冲罐中出来的空气经压力控制后进入混合器;4)控制燃气和空气流量调节混合器中燃气和空气的体积比,得到均匀的混合气体;5)混合气体进入装有分子筛类吸附剂的气体净化装置,得到净化的混合气体;6)净化的混合气体进入火焰复合机进行火焰复合,得到低气味低VOC复合表皮的技术方案,较好地解决了该问题,可用于汽车内饰复合表皮的工业生产中。
