More Information
Summary:The invention provides a preparation method of an anti-aging urea resin foamed plastic plate. The preparation method comprises the following steps: (a) preparation of a urea resin viscous solution; (b) normal-temperature foaming treatment; (c) solidifying and shaping. The invention discloses the preparation method of the anti-aging urea resin foamed plastic plate. The preparation method is simple in process and convenient to operate; by optimizing the technical formula and reasonably adding a slow-release disacidifying agent, the aging resistance of the urea resin foamed plastic plate is greatly enhanced.
