摘　　要：目的节约植物纤维用量,以陶瓷纤维加填抄片,评估废纸浆/陶瓷纤维抄造纸的实用性。方法使用KH-550硅烷偶联剂对陶瓷纤维进行表面处理,将未处理陶瓷纤维与处理的陶瓷纤维以一定比例加填到废纸纤维中,抄造手抄片,比较手抄片的紧度、撕裂度、环压强度、耐折度和抗压强度,并对手抄片的微观形貌进行观测。结果陶瓷纤维交错分散于纸纤维之间。经过KH-550硅烷偶联剂处理的陶瓷纤维加填后,当质量分数<20%时,手抄片的撕裂度、环压强度、抗张强度随纤维含量的增加而下降;当质量分数>20%后,以上性能均随陶瓷纤维含量的增加而上升。手抄片的耐折度随含量的增加明显下降。抄片的环压强度显著提高,陶瓷纤维质量分数为40%时,环压强度为3.81 kN/m,为废纸纤维手抄片的2.06倍。结论加填陶瓷纤维质量分数至40%,不仅节约了植物原材料,也会提高抄造纸的环压强度,可用于承受高环压强度的纸质材料。The work aims to save plant fiber raw materials,and use ceramic fiber as filler fiber to evaluate the practicability of waste paper pulp/ceramic fiber for papermaking.After treating the surface of ceramic fiber with KH-550 silane coupling agent,the untreated and treated ceramic fibers were added in the handsheets at a certain proportion.The properties of the handsheets,including tightness,tear index,ring crush compression resistance,folding resistance and tensile strength were compared.And the micro morphology of the handsheets was observed.The results showed that the ceramic fibers were interlaced and dispersed among the paper fibers.When the mass fraction was less than 20%,the tear index,ring crush compression resistance,and tensile strength of the handsheets treated with KH-550 silane coupling agent decreased with the increase of the fiber content;when the mass fraction was more than 20%,the above properties all increased with the increase of fiber content.But the folding resistance of handsheets decreased significantly with the increase of treated ceramic fiber.The ring crush compression resistance of the handsheets was significantly improved.When the mass fraction of ceramic fiber was 40%,the ring crush compression resistance was 3.81 kN/m,which was 2.06 times that of the waste paper fiber handsheets.Adding ceramic fiber to 40%by mass not only saves raw materials of plant,but also improves the ring pressure compression resistance of handsheets.It can be used for paper materials with high ring crush compression.
