Heat preservation and sound insulation polyurethane plate and preparation method of polyurethane core layer of polyurethane plate

Abstract

The invention relates to a polyurethane plate, and particularly provides a heat preservation and sound insulation polyurethane plate. The heat preservation and sound insulation polyurethane plate comprises an upper color plate and a lower color plate. The lower surface of the upper color plate is connected with a polyurethane core layer. A sound adsorption layer is arranged on the lower surface of the polyurethane core layer. A heat preservation material plate is arranged between the sound adsorption layer and the lower color plate and is thinner than the polyurethane core layer. At least two sound adsorption grooves are formed in the surface, making contact with the upper color plate, of the polyurethane core layer. The lengths of the sound adsorption grooves and the length of the polyurethane core layer are consistent. A plurality of through holes are formed in the surface, opposite to the sound adsorption grooves, of the upper color plate. Sound adsorption holes are formed in the bottoms of the sound adsorption grooves and are connected with the sound adsorption layer. The heat preservation and sound insulation polyurethane plate provided by the invention is simple in structure, low in weight, high in structural strength, close in connection, good in heat preservation performance and capable of adsorbing sound and reducing noise. A preparation method of the polyurethane core layer is simple in manufacturing process and high in production efficiency, and the prepared polyurethane core layer is good in heat preservation performance and high in heat conductivity.

Description

technical field [0001] The invention belongs to the technical field of polyurethane board foam plastic materials, and in particular relates to a heat-preserving and sound-insulating polyurethane board. Background technique [0002] At present, non-load-bearing partitions and partitions used for modern interior decoration usually use light steel keels as the base, and gypsum boards are pasted on the outside. For brick walls, hollow bricks or solid bricks are built first, and then plywood or gypsum boards are combined. The installation of brick walls with this structure is time-consuming, labor-intensive, and not insulated. In addition, for the convenience of installation, some people use color steel plates as exterior wall materials. However, color steel plates have poor thermal insulation performance, which leads to low room temperature in winter, and poor sound insulation, which affects the lives of indoor personnel.

Problems solved by technology

[0002] At present, non-load-bearing partitions and partitions used for modern interior decoration usually use light steel keels as the base, and gypsum boards are pasted on the outside. For brick walls, firstly build hollow bricks or solid bricks, and then compound plywood or gypsum boards. The installation of brick walls with this structure is time-consuming, labor-intensive, and not insulated.

In addition, for the convenience of installation, some people use color steel plates as exterior wall materials. However, color steel plates have poor thermal insulation performance, which leads to low room temperature in winter, and poor sound insulation, which affects the lives of indoor personnel.
