Description

Technical Field

[0001] This utility model relates to the field of melamine-impregnated paper technology, specifically a flame-retardant and moisture-proof melamine-impregnated paper. Background Technology

[0002] Melamine-impregnated paper, also known as "melamine" paper, is a type of plain paper or printed decorative paper that has been impregnated with amino resin and dried. It has a certain resin content and volatile matter content, and can be glued together or to engineered wood products through hot pressing. Melamine-impregnated paper offers advantages such as improved appearance, enhanced use value, improved physical properties, expanded applications, increased value of engineered wood products, and simplified manufacturing processes (avoiding painting, coating, etc.). With the scarcity of timber resources and the increasing demand for wood products, melamine-impregnated paper is poised for even greater development in the 21st century.

[0003] However, the existing melamine-impregnated paper has poor moisture resistance and flame retardant properties, resulting in a short service life and failing to meet market demands.

[0004] Therefore, it is particularly important to design a flame-retardant and moisture-proof melamine-impregnated paper to overcome the above-mentioned technical defects and improve its overall practicality. Utility Model Content

[0005] The purpose of this invention is to provide a flame-retardant and moisture-proof melamine-impregnated paper to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A flame-retardant and moisture-proof melamine-impregnated paper includes a melamine-impregnated paper body, the melamine-impregnated paper body including a substrate adhesive paper, the top and bottom surfaces of the substrate adhesive paper are both bonded with original impregnated paper, the side of the original impregnated paper away from the substrate adhesive paper is bonded with modified impregnated paper, a carbonaceous foam layer is bonded and filled between the original impregnated paper and the modified impregnated paper, the side of the modified impregnated paper away from the original impregnated paper is uniformly coated with a hydrophobic layer, and the side of the hydrophobic layer away from the modified impregnated paper is uniformly coated with a flame-retardant layer.

[0008] As a preferred embodiment of this utility model, the substrate adhesive paper is selected from adhesive paper containing moisture-proof particleboard content.

[0009] As a preferred embodiment of this utility model, the original impregnated paper is impregnated with amino resin.

[0010] As a preferred embodiment of this utility model, the modified impregnated paper is impregnated with modified amino resin containing flame retardant.

[0011] As a preferred embodiment of this invention, the hydrophobic layer is a high-gloss hydrophobic layer containing fluorocarbon compounds.

[0012] As a preferred embodiment of this utility model, the flame-retardant layer is a water-based polyurethane coating containing inorganic aluminum hydroxide flame-retardant particles.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] In this invention, a flame-retardant and moisture-proof melamine-impregnated paper is provided. The base adhesive paper of this melamine-impregnated paper is made of adhesive paper containing moisture-proof particleboard. Using moisture-proof particleboard (expansion rate ≤10%) as the base material reduces water absorption at the source. Original impregnated paper and modified impregnated paper are sequentially glued to both sides of the base adhesive paper. The double-layer impregnation increases the service life. Furthermore, the modified impregnated paper is impregnated with modified amino resin containing flame retardants, allowing the flame-retardant components to penetrate evenly into the fibers. To improve its overall flame retardant performance, a carbonaceous foam layer is inserted between the original and modified impregnated paper layers. This effectively absorbs permeating moisture and reduces substrate expansion. A high-gloss hydrophobic layer containing fluorocarbon compounds is bonded to the surface to block water molecule penetration. Finally, a water-based polyurethane coating containing inorganic aluminum hydroxide flame-retardant particles is added to enhance fire spread resistance and flame retardant properties. This entire structure improves the flame retardant and moisture-proof capabilities of the melamine impregnated paper, extending its service life. Attached Figure Description
