Gluing-free thermal insulating decorative board and manufacturing method thereof

Abstract

The invention discloses a gluing-free thermal insulating decorative board and a manufacturing method thereof. The gluing-free thermal insulating decorative board comprises a flexible finish coat and a board layer. A transparent protective film surface layer is arranged outside the flexible finish coat. A rigid foam polyurethane insulation coating is manufactured on the board layer directly in a foaming mode by adoption of rigid foam polyurethane, and a polymer sheet is compounded on the rigid foam polyurethane insulation coating. The manufacturing method comprises the steps that a decorative layer is placed onto a polyurethane lamination continuous production line; the decorative layer is directly coated with a rigid foam polyurethane foam material; and when the rigid foam polyurethane is foamed, the polymer sheet is compounded on the polyurethane lamination continuous production line. Since the bonding performance of the rigid foam polyurethane in the foaming and forming process is utilized, the rigid foam polyurethane insulating coating is firmly boned with the decorative layer, and the problem that in the prior art, a bonding agent is adopted, the decorative plate is separated from the rigid foam polyurethane insulating coating, and falling is caused can be completely solved. According to the manufacturing method, the production cost is low, the weather fastness is good, the product quality is high, the manufacturing efficiency for the gluing-free thermal insulating decorative board is high, fast industrialization production can be achieved, and the gluing-free thermal insulating decorative board and the manufacturing method thereof have wide market prospects.

Description

technical field [0001] The invention relates to an adhesive-free thermal insulation decorative board, in particular to an adhesive-free thermal insulation decorative board and a manufacturing method thereof. Background technique [0002] At present, the commonly used thermal insulation materials for external wall thermal insulation and decorative panels at home and abroad are generally organic and inorganic. Decorative materials usually include stone, ceramic tiles, real stone paint, colorful water-in-water paint, etc. Adhesives are compounded. At present, it is impossible to produce thermal insulation decorative panels without using adhesives. Generally, thermal insulation decorative panels are heavy, hard, fragile, and high in energy consumption.

Problems solved by technology

[0002] At present, the commonly used thermal insulation materials for external wall thermal insulation and decorative panels at home and abroad are generally organic and inorganic. Decorative materials usually include stone, ceramic tiles, real stone paint, colorful water-in-water paint, etc. Adhesives are compounded. At present, it is impossible to produce thermal insulation decorative panels without using adhesives. Generally, thermal insulation decorative panels are heavy, hard, fragile, and high in energy consumption. It falls off, causing public hazards because of its radioactive pollution. It is heavy and hard, and it will cause accidents such as smashing and injuring people after falling off.

Adhesives are used in the production process, which consumes materials, labor, and time when pasting, and is easily polluted by the adhesive. The color is relatively single and the decorative effect is poor. limit
