| titleOfInvention | A kind of preparation technology of water-soluble methyl-etherified melamine resin |
| abstract | The present invention relates to a kind of preparation technology of water-soluble methyl-etherified melamine resin.The process route that the present invention uses, comprises the following steps：Paraformaldehyde, formalin, methanol are added to reaction bulb and is well mixed, adds adjusting PH with base value 8.0~9.0；Stirring is warming up to 50~60 DEG C, adds melamine, is continuously heating to 80~90 DEG C, 1~2h of insulation reaction;50~60 DEG C are cooled to, acid adding adjusts pH value 5.0~7.0, insulation reaction, observes cloud point；Add adjusting PH with base value 8.0~10.0, terminating reaction；Water and methanol are removed under vacuum condition, obtains methyl-etherified melamine resin product.The present invention replaces part formalin using paraformaldehyde, reduces formaldehyde dosage, and simple to operate, production cost is low, and resulting methyl-etherified melamine resin product, and water-soluble complete molten, free formaldehyde content is low, has good development and application prospect. |
