    • Flame retardant and water resistant products are produced from bio-based materials such as lignin cellulose containing materials. The lignin cellulose materials are modified by the method of delignification. The method of this invention utilizes an amino compound in an aqueous solution to react with the lignin in the lignin cellulose and the amino lignin and freed lignin becomes water soluble. The amino compound also reacts with the non-water soluble lignin still attached to the cellulose and also to the cellulose that is produced. Other products are produced in this method such as carbohydrates, hemi-cellulose, rosins, waxes, alcohols and other products. The amino lignin, lignin, amino lignin and amino cellulose is reacted with many organic and inorganic compounds such as aldehydes, polyisocyanates, epoxies, polycarboxylic acids, vegetable oils and many other compounds to produce resins and adhesives which may be used to produce products such as molded products, particleboard, plywood, ABS, etc. which are flame retardant and water resistant.
    • 阻燃和防水产品由生物基材料(如含木素纤维素的材料)生产。 木质素纤维素材料通过脱木质素的方法进行改性。 本发明的方法利用水溶液中的氨基化合物与木质素纤维素中的木质素反应,氨基木质素和木质素变得水溶。 氨基化合物还与仍然附着在纤维素上的非水溶性木质素以及所生产的纤维素反应。 其他产品以这种方法生产,如碳水化合物,半纤维素,松香,蜡,醇等产品。 氨基木质素,木质素,氨基木质素和氨基纤维素与许多有机和无机化合物如醛,多异氰酸酯,环氧化合物,多元羧酸,植物油和许多其它化合物反应,以生产可用于生产产品的树脂和粘合剂 模制产品,刨花板,胶合板,ABS等,其阻燃和防水。

    • It has now been found that when there is a partial or complete replacement of the sodium hydroxide that is used to make a sodium phenolate resole resin by a molar equivalent of potassium hydroxide, a far faster curing resin is obtained. Such potassium-modified phenolic resins exhibit significant improvement in cure speed without loss of flowability. To the contrary, these resins act as though they were lower molecular weight condensation products. Reduced application rates are possible. The combination of faster cure and lower application rates has allowed such resins to be used as effective adhesives for plywood, for example, with veneer and interior plies having a higher moisture content than was previously possible. Generally, resins according to the invention may contain from about 1% to about 14%, and preferably from about 1% to about 7% by weight, of potassium hydroxide, or more.
    • 现在已经发现,当通过摩尔当量的氢氧化钾部分或完全替代用于制备苯酚钠酚醛树脂的氢氧化钠时,获得了更快的固化树脂。 这种钾改性酚醛树脂在固化速度方面表现出显着的改善,而不损失流动性。 相反,这些树脂就像低分子量缩合产物一样。 降低应用率是可能的。 较快固化和较低施用率的组合使得这种树脂可用作胶合板的有效粘合剂,例如,具有比先前可能的更高水分含量的单板和内层。 通常,根据本发明的树脂可以含有约1重量%至约14重量%,优选约1重量%至约7重量%的氢氧化钾或更多。
