| titleOfInvention | Melamine resin and preparation method and application thereof |
| abstract | The invention relates to the technical field of amino resin preparation, and particularly relates to melamine resin and a preparation method and application thereof. The preparation method of the melamine resin comprises the following steps: (1) mixing and stirring melamine, formaldehyde and water, then heating, and adjusting the pH value to obtain a hydroxymethyl monomer solution; (2) adding the hydroxymethyl monomer solution into a sulfonic acid compound solution, and continuously stirring to obtain a prepolymer solution; (3) and adding the epoxy compound into the prepolymer solution, and continuously stirring to obtain the melamine resin. The preparation method has the advantages that through measures of reducing the using amount of formaldehyde in the raw materials, reducing the generation of methylene ether bonds and the like, the content of the formaldehyde is greatly reduced, simultaneously, the water solubility and the storage stability of the product are improved, and the problems of high cost, reduced application performance and the like are solved. |
