Abstract

The invention relates to the field of composite board preparation, in particular to a polyurethane foam composite board, a preparation system and a preparation process. The process comprises the following steps that S1, a metal plate is placed on the upper sides of a plurality of triangular convex edges on a flat plate, so that two barrier strips block the front side and the rear side of the metalplate correspondingly; S2, when a pressing frame is pressed downwards, the pressing frame can be pressed on the metal plate, and then a plurality of triangular-prism-shaped grooves are formed in themetal plate by pressing by the aid of the plurality of triangular convex edges; S3, the lower portions of multiple rotating rollers are moved to the lower side of the pressing frame, then the multiplerotating rollers are driven to roll left and right on the metal plate when the pressing frame moves left and right, and then the triangular convex edges are further pressed on the metal plate; and S4, the metal plate subjected to groove pressing enters the upper portion of a lower rotating wheel, when the metal plate continuously moves leftwards, the lower rotating wheel and felt are driven to rotate, mucilage glue is added into a groove box, the felt rotates to roll up the mucilage glue, and the felt smears the mucilage glue on the plurality of triangular-prism-shaped grooves in the lower side of the metal plate.

Description

technical field [0001] The invention relates to the field of composite sheet preparation, and more specifically relates to a polyurethane foam composite sheet, a preparation system and a preparation process. Background technique [0002] The application number is CN200910090090.7, which discloses a polyurethane foam composite board and its preparation method. The invention discloses a polyurethane foam composite board, which consists of a panel and a composite core board. Light plane damping plate and porous damping plate arranged in a regular square or triangular manner. The composite core plate is formed by bonding one side of the open-cell polyurethane molding plate and the porous damping plate to form a single-sided core plate. The single-sided core plate and the light plane damping panel are in In the forming mold, the two-component polyurethane foam composite materials A and B are foamed and cured to form a multi-layer structure composite, and the polyurethane foam com...
