Melamine foam and fiber blended preparation technology

Abstract

The invention relates to a melamine foam and fiber blended preparation technology which comprises the following steps that (1), melamine foam waste is smashed into melamine foam smashed materials withirregular particle sizes for standby application; (2), one layer of melamine foam smashed materials obtained in the step (1) is laid on a conveyor belt through a paving device, and a bottom layer melamine foam smashed material layer with the thickness being 1-2 cm is obtained; (3), fibers are sprayed on the bottom layer melamine foam smashed material layer obtained in the step (2) with the sprayangle being 45 degrees to serve as a bonding layer; (4), one layer of melamine foam smashed materials obtained in the step (1) is laid on the bonding layer in the step (3), and a primary sectional material with a composite layer is obtained, wherein the thickness of the layer of melamine foam smashed materials is 1-4 cm; and (5), the primary sectional material obtained in the step (4) is hot-pressed through a hot-pressing machine under the state of 200-230 DEG C and is quickly cooled, and melamine foamed plastic is obtained. The melamine foam and fiber blended preparation technology has the advantages of being capable of saving energy, environmentally friendly, high in density, good in cleaning effect, durable and high in noise reduction coefficient.

Description

technical field [0001] The invention belongs to the technical field of sound-absorbing materials, and in particular relates to a preparation process based on melamine foam and fiber blending. Background technique [0002] Melamine foam, also known as melamine foam, is a high-opening three-dimensional network structure foam made of melamine and formaldehyde resin with additives. It can absorb stains with a little water, and has obvious cleaning effects. It is widely used in cleaning Scale, grease and dirt on any light and hard surface such as tableware, kitchen utensils, bathrooms, tiles, home appliances, households, etc. In the process of producing melamine foam for cleaning, a whole piece of melamine foam will be cut and cut according to needs After that, a large amount of waste will be generated. Usually, these melamine foam wastes are treated by incineration, burial, etc., which will cause serious waste of raw materials for enterprises, and will also cause serious polluti...

[0002] Melamine foam, also known as melamine foam, is a high-opening three-dimensional network structure foam made of melamine and formaldehyde resin with additives. It can absorb stains with a little water, and has obvious cleaning effects. It is widely used in cleaning Scale, grease and dirt on any light and hard surface such as tableware, kitchen utensils, bathrooms, tiles, home appliances, households, etc. In the process of producing melamine foam for cleaning, a whole piece of melamine foam will be cut and cut according to needs After that, a large amount of waste will be generated. Usually, these melamine foam wastes are treated by incineration, burial, etc., which will cause serious waste of raw materials for enterprises, and will also cause serious pollution to the environment.

On the other hand, melamine foam is also often used to silence equipment with severe noise. Currently, the density of sound-absorbing holes in melamine foam used for sound-absorbing is low, resulting in unsatisfactory sound-absorbing effects.
