Abstract

The invention discloses a melamine phenolic resin glass preparation method. The preparation method comprises the following steps that 1, raw materials are weighed, SiO2, Al2O3, Na2SiO3, CaSiO3, Na2O, CaO and La2O30 are evenly mixed, the mixture is put in a crucible, heating is performed to reach 1650 DEG C, and heat-preservation reaction is performed for 5-6 hours; 2, stillingia oil modified melamine phenolic resin is added, heat preservation is performed for 2-3 hours for full melting and clarification; 3, melt is poured into a preheated graphite mold, irradiation is performed with ultraviolet light with the wavelength smaller than 50 nanometers for 1-2 minutes for forming; 4, nucleating and crystallization are performed to obtain glass. The melamine phenolic resin glass is strong in compressive strength and bending strength, due to the fact that ultraviolet light irradiation produces a certain physicochemical property change to the melt, and the glass prepared by adopting the preparation method is not likely to break under the effect of an impact force.

Description

technical field [0001] The invention discloses a method belonging to the field of glass manufacturing, in particular to a preparation method of melamine phenolic resin glass. Background technique [0002] Melamine copolymer resin is a resin obtained by adding the third component to the melamine and formaldehyde polymerization system.
