Problems solved by technology

[0002] Most of the traditional architectural decoration materials are stone and gypsum board. Due to the large size of these decorative materials, complex installation and processing technology, and simple shape, the construction cost increases, and due to the limitation of the material's own performance, it cannot express the architectural designer's ideas well. plan for design

Abstract

The invention discloses a preparation method of a flame-retardant fluorocarbon aluminum veneer for furniture decoration. The preparation method comprises the following process steps: firstly, performing sheet metal processing on an aluminum alloy panel; performing pretreatment (including chromium-free passivation) on the aluminum alloy panel; carrying out treatment by adopting a fluorine-silicon water-based coating to form a fluorocarbon primer layer; and then carrying out treatment by adopting a flame-retardant fluorocarbon finish paint layer to form a fluorocarbon bottom surface layer. The fluorocarbon bottom surface layer adopts fluorocarbon resin and organic silicon resin as film forming materials, and then hydroxyl modified silicon dioxide and magnesium aluminum base layered compositehydroxide are added, so that the strength of a film forming framework can be effectively improved; and an organic tin catalyst and a sodium borate catalyst are added, so that the film forming densitycan be remarkably improved. According to the preparation method disclosed by the invention, the magnesium aluminum base layered composite hydroxide is added, so that a magnesium aluminate spinel structure can be formed at a high temperature, and can resist high temperature of 1800 DEG C or above, and the effect is very good; and moreover, the layered structure is further beneficial for adsorbingtoxic smoke, so that the safety of the material can be effectively improved.

Description

Technical field [0001] The present invention relates to the technical field of building materials, and more particularly to a method for preparing a flame-retardant fluorocarbon aluminum substrate for furniture decoration. Background technique [0002] Most of the traditional architectural decoration materials use stone, gypsum board, because these decorative materials are complex, the installation and processing process is complex, and the shape is simple, leading to the increase in building cost, and cannot express architects due to the limitations of material self-performance. plan for design. Because of its excellent processability and weight, low price, low price, can be widely used in the field of architectural decoration, greatly reduced materials and installation costs, shorten construction cycle. In recent years, with the demand for market development and the improvement of industry product grade, people's various performance requirements for aluminum boards have become ...
