Description

technical field

[0001] The invention belongs to the technical field of polymer materials, and in particular relates to a modified melamine rigid foam material and a preparation method thereof. Background technique

[0002] Melamine rigid foam material is a new type of material in the field of exterior wall thermal insulation developed in recent years. Compared with other rigid thermal insulation materials such as polyurethane, polystyrene, and phenolic resin, it is The flame retardant effect can be achieved at the next level, and it has the characteristics of low thermal conductivity, light weight, low smoke, and environmental protection; however, the control requirements for various components and parameters in the synthesis and foaming process of melamine resin are relatively strict, the components are complex, and the conditions are changeable. As a result, the product quality stability is not very good, and the inherent triazine ring structure of melamine makes the foame...
