A kind of preparation technology of melamine foam and fiber blending

Abstract

The invention relates to a preparation process of melamine foam and fiber blending, which comprises the following steps: 1) crushing melamine foam waste into melamine foam scraps with irregular particle sizes for use; 2) using a laying device on a conveyor belt Paving one deck step 1) the melamine foam scrap that obtains, obtains the bottom melamine foam scrap layer that thickness is 1cm-2cm; 3), on the bottom melamine foam scrap layer that obtains in step 2) with 45 The jet angle spraying fiber of ° is as bonding layer; 4), on the bonding layer in step 3) pave one deck thickness between 1cm-4cm by the melamine foam fragment that obtains by step 1), obtains having The primary profile of the composite layer; 5), the primary profile obtained in step 4) is hot-pressed at 200°C-230°C with a hot press and cooled rapidly to obtain melamine foam; the present invention has energy-saving, environmental protection, and high density , Good cleaning effect, durable and high 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 of melamine foam used as sound-absorbing foam is low, resulting in unsatisfactory sound-absorbing effect.
