高粘度苯基苯酚甲醛树脂的固体酸催化法合成新工艺研究

Study on a New Composition Technology of High-adhesive Phenyl Phenol and Formaldehyde Resinby Solid Acid Catalysis

介绍了以邻苯基苯酚和甲醛为原料,运用正交实验法,经过固体酸(阳离子交换树脂)催化缩合、过滤、蒸馏等过程,研制出合成苯基苯酚甲醛树脂产品的一种新型工艺路线。产品外观为红棕色粘稠液体,pH值接近7,能够耐水和酸碱,稳定性好,主要用于船舶漆、粘合剂和橡胶制品等领域。

With pnenyi phenol and formaldehyde as material, using orthogonal experiment means, through catalysis condensation, filtration, and distillation etc process by solid acid catalyst （cation exchange resin）, a new composition technology of phenyl phenol and formaldehyde resin was achieved. This product was vicious reddle liquid, pH was approximate to 7, and it was waterproof, acid- resistant alkali proof and steady, mainly applied to marine paint, adhesive and rubber product etc area.
