Abstract

The invention discloses a fiber-reinforced melamine resin foam sponge and a preparation method thereof and belongs to the technical field of foam materials. The fiber-reinforced melamine resin foam sponge is prepared from the following raw materials in parts by weight: 90-110 parts of melamine resins, 5-10 parts of foaming agents, 5-10 parts of stabilizers, 2-10 parts of curing agents, 2-10 weight parts of stabilizers, 2-10 weight parts of curing agents and 1-10 parts of reinforced fibers. The invention further discloses the preparation method of the fiber-reinforced melamine resin foam sponge. After the fibers are added in the melamine resin foaming process, the cell size can be obviously reduced, the uniformity is improved, the compression strength and elasticity modulus are obviously enhanced, the toughness and dimensional stability are improved, and the fiber-reinforced melamine resin foam sponge still has excellent heat stability and flame-retardant property.

Description

technical field [0001] The invention relates to the technical field of foam materials, in particular to a fiber-reinforced melamine resin foam sponge. Background technique [0002] Melamine resin, also known as melamine-formaldehyde resin, is a polymer obtained by the reaction of melamine and formaldehyde. A cross-linking reaction occurs during processing and molding, and the product is an infusible thermosetting resin. It is customarily called amino resin together with urea-formaldehyde resin. [0003] Melamine resin foam sponge refers to the use of melamine resin to make melamine formaldehyde foam through foaming reaction. This foam is non-flammable, water-resistant, heat-resistant, aging-resistant, arc-resistant, chemical-resistant, and has good insulation properties and gloss. And mechanical strength, but also has a good sound-absorbing effect. Therefore, it is widely used in sound-absorbing and flame-retardant buildings, automobiles, aircraft carriers, submarines, etc...
