Phenolic resin binding agent for sliding plate brick and preparation method of phenolic resin binding agent
The invention provides a phenolic resin binding agent for a sliding plate brick. The phenolic resin binding agent is prepared from the following raw materials in parts by mass: 350 to 450 parts of phenol, 150 to 250 parts of p-cresol, 800 to 1000 parts of formaldehyde aqueous solution, 250 to 350 parts of triphenol derivative, 20 to 30 parts of sodium hydroxide, 100 to 140 parts of epoxide, 10 to 20 parts of acid, 50 to 70 parts of urea, 50 to 80 parts of methyl glycolate and 10 to 30 parts of methanol. According to the phenolic resin binding agent disclosed by the invention, the triphenol derivative and the epoxide are added, and particularly the compounded triphenol derivative and 2, 2 '-[oxy-bis (2, 1-ethylideneoxy-methylene)] diethylene oxide are added, so that the binding property of resin can be improved, and the pressure resistance and breaking strength of a product after phenolic resin is cured can be improved; by adding a mixture of glacial acetic acid and boric acid, the oxidation resistance and heat resistance of the resin can be improved; the use frequency of the sliding plate brick is improved.
本发明提供一种滑板砖用酚醛树脂结合剂，包括如下质量份的原料：350‑450份苯酚、150‑250份对甲酚、800‑1000份甲醛水溶液、250‑350份三酚衍生物、20‑30份氢氧化钠、100‑140份环氧化物、10‑20份酸、50‑70份尿素、50‑80份羟乙酸甲酯、10‑30份甲醇。本发明的酚醛树脂结合剂加入三酚衍生物和环氧化物，特别是复配的三酚衍生物、2,2’‑[氧基双(2,1‑亚乙基氧基亚甲基)]双环氧乙烷能够改善树脂的粘结性能，提高酚醛树脂固化后产品的耐压和抗折强度；加入冰醋酸与硼酸的混合物，能够改善树脂的抗氧化性和耐热性；提高滑板砖的使用次数。
