Abstract

The invention provides a modification method of melamine foam, and relates to the technical field of foam material modification. Modified melamine foam is prepared from, by weight, 40-50 parts of melamine, 20-30 parts of formaldehyde, 4-5 parts of polyvinyl alcohol, 1-2 parts of copper sulfate, 1-2 parts of zinc chloride, 2-3 parts of aluminum stearate, 3-4 parts of a silane coupling agent, 2-4 parts of a stabilizer, 1-3 parts of an antioxidant, 3-5 parts of a plasticizer, 5-6 parts of a crosslinking agent and 6-8 parts of a foaming agent. The modification process of the melamine foam is optimized, and parts of additives are reasonably added, so the problems of high hardness, fragility, residue dropping and low strength of the melamine foam are effectively solved, and the performances of the melamine foam are obviously, thereby the quality of the melamine foam material is further improved.

Description

technical field [0001] The invention relates to the technical field of foam material modification, in particular to a method for modifying melamine foam. Background technique [0002] Melamine foam is a new type of high temperature resistant flame retardant material with excellent high temperature resistance and flame retardancy, and melamine formaldehyde resin foam is a new type of foam with high open cell ratio, which has low density and good mechanical processing performance , outstanding sound absorption, excellent flame retardancy, but pure melamine formaldehyde resin is a thermosetting polymer, and melamine foam materials are widely used in various fields, and have achieved good results. [0003] Melamine foam has a three-dimensional network cross-linked structure, and contains a large number of rigid triazine rings in the molecule, which makes melamine formaldehyde resin foam have the characteristics of high hardness, fragility, slag drop, and low strength, so melamin...
