Preparation technology of flame-retardant wallpaper

Abstract

The invention provides a preparation technology of a flame-retardant wallpaper. The preparation technology comprises the following steps of preparing a flame-retardant solution, mixing APP (polyammonium phosphate), PER (pentaerythritol) and GP (guanidine phosphate) according to a weight ratio of 10 to (3 to 5) to (5 to 10); adding OMMT (organic montmorillonite) into the flame-retardant solution, stirring and mixing; utilizing full-screen coating equipment with size of 80 meshes to perform full-screen coating on a substrate by the flame-retardant solution, and coating for multiple times; utilizing a press roll to extrude the coated substrate at high temperature of 40 to 60 DEG C; drying the substrate, and coating a waterborne ink printing layer; utilizing full-screen coating equipment withsize of 100 meshes to print the surface, so as to complete the production of the wallpaper. The preparation technology of the flame-retardant wallpaper has the advantages that the flame-retardant solution is covered on the surface of the substrate in a 80-mesh full-screen way; the substrate is extruded by the press roll at high temperature, so that the flame-retardant solvent can permeate into thesubstrate, thereby forming the flame-retardant wallpaper; while the production efficiency is improved, the preparation method is suitable for batch production, and the production cost of enterprisesis reduced.

Description

technical field [0001] The invention relates to a preparation process of flame-retardant wallpaper. technical background [0002] At present, wooden wallpaper is a new type of wallpaper made of decorative veneer (surface layer) and base paper (non-woven paper). As a whole, it is healthy, environmentally friendly, green and safe, and has a good market prospect. However, wood and non-woven paper are combustible and combustible materials, so it is necessary to conduct flame-retardant research on such wallpapers. [0003] The flame-retardant and fire-resistant wallpaper that is widely used now uses 100-200g / ㎡ asbestos paper as the base material, and at the same time, the PVC plastic-coated material on the surface of the wallpaper is mixed with a flame retardant, so that the wallpaper has a certain fire-proof and flame-retardant performance. Flame retardant wallpaper is usually made by adding flame retardants to the inside of the paper or covering the surface of the paper throu...

[0005] At the same time, the existing flame-retardant wallpaper preparation process is to soak the base material in the flame-retardant liquid, and use ultrasonic stirring to make the flame retardant penetrate into the base material. Such a process will increase the production cost of the enterprise and damage the production efficiency. , is not conducive to the economic benefits of the enterprise
