Problems solved by technology

[0008] (2) The production process is complicated to operate, and the technical threshold and capital threshold are relatively high
[0009] (3) The physical foaming agent used in the current process is generally low-boiling volatile alkanes. These alkanes are generally flammable substances, which will be volatilized during the foaming process and form a mixed gas in the tunnel, which increases the ease of foaming. Flammable and Explosive Hazard

Abstract

The invention provides a melamine foam material and a preparation method thereof. The melamine foam material of the present invention is mainly prepared from the following raw materials in parts by mass: 100 parts of melamine resin, 0.5-10 parts of surfactant, 5-30 parts of foaming agent, 0-10 parts of auxiliary agent, and 2-20 parts of catalyst 0-30 parts of water. The preparation method of the melamine foam material of the present invention comprises the following steps: (1) preparation of the main foaming material—melamine resin; (2) preparation of foaming auxiliary materials; (3) foaming preparation of the melamine foam material. The melamine foam material of the invention has excellent and stable mechanical properties, and its mechanical properties are not affected by the storage time of raw materials. The melamine resin used in the present invention has a certain storage stability, which can separate the production of melamine resin and the foaming section from the space and time interval, so that the foam production is more stable, which is beneficial to foaming, and greatly reduces the general production cost. The technical and capital thresholds invested by investors simplify the production process.

Description

technical field [0001] The invention relates to the field of melamine foam materials, in particular to a melamine foam material and a preparation method thereof. Background technique [0002] Melamine foam, also known as melamine foam, is a new type of foam plastic with high opening rate and low density. It has excellent flame retardancy, sound absorption, heat insulation, safety and non-toxicity, and has good post-processing. Compared with traditional foam plastics such as polyurethane foam and polystyrene foam, melamine foam has excellent flame retardant properties without adding flame retardants, cokes without dripping when burning, and produces smoke density higher than that of traditional foam materials. These excellent properties make melamine foam an ideal environmentally friendly flame-retardant material, which is widely used in public places, vehicles, building sound absorption, thermal insulation and other fields. [0003] As early as the 1960s, patents such as US...
