Abstract

The invention discloses a flame-retardant antifouling cellulose laminated composite board for rail transit interiors and a preparation method of the flame-retardant antifouling cellulose laminated composite board. The invention belongs to the field of rail transit interiors. The invention aims to solve the technical problems that the existing cellulose laminated composite material has poor fireproof and antifouling properties and cannot meet the application requirements of rail transit interior materials. The flame-retardant antifouling cellulose laminated composite board for the rail transit interior decoration is formed by hot-pressing and curing a surface layer and a core layer which are laminated, the surface layer is a plurality of layers of cellulose paper impregnated with modified melamino-formaldehyde resin, and the core layer is formed by compounding a plurality of layers of aramid paper impregnated with modified melamino-formaldehyde resin and cellulose paper impregnated with modified melamino-formaldehyde resin, which are alternately laminated. The composite board provided by the invention is formed by hot-pressing a plurality of cellulose materials impregnated with modified melamine formaldehyde resin with rapid infiltration and flame retardant properties. The limit oxygen index reaches 36.5; the combustion performance reaches grade A; the anti-pollution performance can reach level 5, and excellent anti-pollution and flame-retardant performance is achieved.

Description

technical field [0001] The invention belongs to the field of rail transit interior decoration, and in particular relates to a flame-retardant and antifouling cellulose laminated composite plate for rail transit interior decoration and a preparation method thereof. Background technique [0002] Cellulose laminated composite board is a decorative material prepared by impregnating decorative paper with melamine formaldehyde resin and multi-layer cellulose paper impregnated with phenolic resin through high temperature and high pressure. Due to its high weather resistance, high stability, high wear resistance, It has the characteristics of impact resistance, strong decoration and waterproof, and can be used for trains running in complex environments, end wall panels, electrical cabinet panels and tea table panels, etc. [0003] In recent years, the rapid development of domestic rail transit has the characteristics of high density of personnel and relatively closed environment. As...
