Process of making press molded materials using heat activated tertiary amine urethane catalysts |
摘要 |
This invention concerns a process for the manufacture of a press molded material, comprising applying diisocyanate, polyol, and catalyst to a wood material, wherein the catalyst is a tertiary amine-carboxylic acid salt that is blocked at room temperature and becomes unblocked at an elevated temperature, and heating the resulting mixture to a temperature effective to unblock the salt to produce unblocked tertiary amine. The press molded material can be an orientated strand board (OSB).
