Inorganic high-pressure fireproof wear-resistant decorative plate and production method thereof

Abstract

The invention relates to a decoration sheet material, and concretely relate to an inorganic high-pressure fireproof wear-resistant decorative plate and a production method thereof. The decorative plate comprises a fireproof substrate, a buffer layer is arranged on the fireproof substrate, a decorative layer is arranged on the buffer layer, a wear-resistant protection layer is arranged on the decorative layer, the fireproof substrate is made by an inorganic non-combustible sheet material pressurized and impregnated by thermosetting alcohol-soluble phenolic resin; and the buffer layer is made by brown paper impregnated by thermosetting melamine resin adding a fire retardant and coated with alcohol-soluble phenolic resin on the back. The decorative plate has the advantages of water resistance, impact resistance, good size stability, high tensile strength and anti-folding intensity, pollution resistance on the surface, wear resistance, scratch resistance, no combustion encountered with fire, self extinguishing after away from the fire, good stability under high temperature, no decomposition of released asphyxiating toxic gasand smog, simple subsequent processing, sawing, no edge-breaking while boring, and no fragmentation.

Description

technical field [0001] The invention relates to a decorative board, in particular to an inorganic high-pressure fireproof and wear-resistant decorative board and a production method thereof. Background technique [0002] With the improvement of people's living standards, the requirements for aesthetics, functionality, and individuality of decoration are gradually increasing. Interior decoration materials, including countertops, wall panels, and furniture, need to meet appropriate strength, fire resistance, stain resistance, and corrosion resistance. , antibacterial and mildew-proof, low release of formaldehyde harmful to human body, beautiful and practical, etc., to meet the requirements of safety, practicability, and aesthetics of decoration. Therefore, the material requirements for interior decoration materials are gradually increasing. [0003] At present, my country's decorative boards mainly include wood-based blockboard, plywood, laminated wood, density boards based on...

AI Technical Summary

Problems solved by technology

Wood or wood-based panels are flammable substrates, which are easy to burn and release suffocating gas when exposed to open flames or long-term high-temperature baking. The safety is poor, and a large amount of adhesives are used in the manufacturing process of the substrates, and the product releases high formaldehyde. And most of the surface needs to be used after painting and coating. Most of the paints and coatings contain volatile solvents such as benzene, toluene and other organic pollutants, which cause potential harm to the health of users or occupants, and poor environmental protection; inorganic plates have no plastic deformation at room temperature , high compressive strength, but poor tensile strength, flexural strength and impact resistance, brittle fracture, because of high surface energy, it is difficult to paint and paste decorative products on the surface, and the decorative performance is poor

PVC boards and aluminum-plastic panels with polymer materials as the base material use PVC and other polymer plastics as the molding base material, which has poor fire resistance and flame retardancy, and releases a large amount of toxic, harmful, and suffocating gases during combustion, which is the cause of casualties in the event of a fire. The main reason

At present, high-pressure decorative laminates, which are widely used in decoration, are made of paper, such as decorative surface paper and base paper, etc., impregnated with thermosetting resin and then produced under high temperature and high pressure, which can form decorative laminates with various colors and various surface treatments. The disadvantage is that since this kind of decorative material is made of paper, although it is impregnated with a resin with certain flame-retardant properties, it can continue to burn in case of fire, and a large amount of toxic gas will be produced during the combustion process; another convenience, this high-pressure decorative laminate The production cost of the board is relatively high, resulting in a high purchase cost in the civil industry, and its wide application is limited

In recent years, people have paid more and more attention to the safety, environmental protection and personalized decoration of construction and decoration materials. These traditional materials are becoming more and more difficult to meet the needs.
