Title:
MANUFACTURING METHOD OF METHYLENATED MELAMINE-FORMALDEHYDE INITIAL CONDENSATE FOR EXPANDED BODY, AND MANUFACTURING METHOD OF MELAMINE RESIN EXPANDED BODY USING THE SAME
Document Type and Number:
Japanese Patent JP2018145381
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a manufacturing method of a methylenated melamine-formaldehyde initial condensate for expanded body extremely good in storage stability and a manufacturing method of a melamine resin expanded body based on the composition, having light weight, rich in plasticity or elasticity, and in which an internal shape is porous.SOLUTION: There is provided a manufacturing method of a methylenated melamine-formaldehyde initial condensate for expanded body obtained by a primary reaction by adding a basic catalyst to a solution containing melamine monomer, formaldehyde and no alcohol and heating them, then a secondary reaction by adding an acidic catalyst and heating them.SELECTED DRAWING: None
