Abstract: In this study, a new PVC plasticizing paste was developed to address the need for optimization
of interfacial binders for space composites. The rheological and bonding properties of the plasticized paste
were investigated by systematically examining the effects of the main components of the formulation on the
viscosity of the paste. In the course of the study, the phenomenon of sticky filaments after the preparation
of spatial composites using different formulated pastes was observed, the peel strength of the composites
was tested, and the surface micromorphology of the polyester fiber mesh after the paste was applied was
also characterized and analyzed using SEM. The results show that the viscosity of the paste system can be
effectively improved by adding the emulsion method paste resin to the micro-suspension method PVC paste
resin. When the content of emulsion paste resin is 50% and the content of nano calcium carbonate is 5~8
PHR, the plasticized paste system not only has a high initial viscosity, but also the viscosity change is relatively
stable, and there is no need to add fumed silica for thickening during production. In addition, the material
also has the use effect of non-stick silk and high peel strength.
Key words: PVC; plasticizing paste; viscosity; space composites

圣奥开发高端橡胶防老剂关键原材料甲基异戊基酮
Sennics develops methyl isopentyl ketone, a key raw material for high-end rubber antioxidants

2025 年 9 月 1 日，圣奥化学发布高端橡胶防老剂关键原材料甲基异戊基酮 (MIAK)。该产品采用自主研发的
领先工艺，不仅有助于圣奥化学橡胶添加剂业务延链补链，也填补了国内行业相关产品空白，将进一步增强化工
新材料产业链供应链韧性。
MIAK 具有良好的溶剂属性以及低密度、低挥发速度、易生物降解等特性，可用于生产高端橡胶防老剂、环
保油漆涂料、数字印刷油墨等。圣奥化学于 2020 年 3 月成立项目组，确立合成 MIAK 的工艺路线。经过数年研发
创新，技术团队突破新型催化剂研制、反应工艺流程优化、过程技术强化和复杂组分分离提纯四大技术难题，成功
开发出 MIAK 合成工艺，并于 2023 年实现 MIAK 连续稳定生产，2024 年推进工业化扩产，2025 年首期 3 000 t/
年 MIAK 产能落地。
圣奥化学将绿色理念融入 MIAK 生产全链条，通过全方位升级技术体系，打磨 “ 反应温和、本质安全、低耗
少排 ” 的绿色生产工艺，实现原料绿色化，“ 三废 ” 近零排放。目前，圣奥化学针对该技术工艺已提交发明专利
申请 3 项、实用新型专利申请 2 项，制定发布 Q/AS971-2022《甲基异戊基甲酮》企业标准，并受中国石油和化
学工业联合会委托，牵头起草《工业用甲基异戊基酮》团体标准。
圣奥化学宣布，MIAK 的共线产品甲基正戊基酮 (MAK) 将于 2026 年投产。MAK 是一种无色且具有香味的
稳定液体，具有高溶剂活性、低蒸发速率、低表面张力和高沸点等特征，作为溶剂可用于涂料、油墨、清洁剂、
制药工业等领域。
