Manufacturing method of super E0 grade Melamine-Urea-Formaldehyde Resin and Adhesive for medium density fiber board using with Super E0 MUF Resin
Manufacturing method of super E0 grade Melamine-Urea-Formaldehyde Resin and Adhesive for medium density fiber board using with Super E0 MUF Resin
invention Super EO grade melamine-urea-formaldehyde resin using this method and medium density fiberboard It relates to an adhesive, formaldehyde and urea to a shaft by a multistage polymerization process, only the molar ratio of formaldehyde polymerization / group in each of the polymerization process within a specific range, and after the aging step a melamine-urea-formaldehyde resin (Melamine -Urea-Formaldehyde Resin, hereinafter 'MUF resin, by making the Abraham) can plunge in and doing the amount of unreacted formaldehyde, medium density fiber board (Medium Density Fiber Board, hereinafter' MDF 'hereinafter) in the manufacture of the resin and a curing agent and the mixture significantly reduces the formaldehyde emission of the resulting MDF with 0.3 / L SUPER E0 (JIS standard), using the following class, and improve the mixing of the curing accelerator to a specific use, as well as decreased production of MDF the formaldehyde emission amount , and sticking the surface of the blister (Sticking) improve the physical properties, such as excellent prevention was SUPER E0 class melamine-urea-relates to a process for the production of an adhesive for density fiber board using the same, of the formaldehyde resin.
