Manufacturing and machining technology for polyurethane sound insulation board

Abstract

The invention provides a manufacturing and machining technology for a polyurethane sound insulation board, and relates to the technical field of sound insulation materials. The manufacturing and machining technology for the polyurethane sound insulation board is completed by adopting a manufacturing and machining device for the polyurethane sound insulation board in a matched mode, and the manufacturing and machining device for the polyurethane sound insulation board comprises a horizontally-placed workbench, wherein a protruding heat preservation box is arranged in the middle of the top end of the workbench, the heat preservation box is of a square structure, and a forming cavity with a square structure is formed in the middle of the top end of the heat preservation box. According to themanufacturing and machining technology, in the process that the formed polyurethane sound insulation board is ejected out from the interior of the forming cavity to the top end of the heat preservation box, scrap storage grooves are formed in the inner wall of the forming cavity at equal intervals, corner burrs of the polyurethane sound insulation board are scraped away through scrap scraping blades arranged at the positions, facing the bottom surface of the inner wall of the forming cavity, of the top ends of groove openings of the scrap storage grooves, and the edge and corner burrs on the surface of the polyurethane sound insulation board moved out after forming are reduced, so that the surface of the polyurethane sound insulation board moved out after forming is clean and tidy.

Description

technical field [0001] The invention relates to the technical field of sound-insulating materials, in particular to a manufacturing process of polyurethane sound-insulating boards. Background technique [0002] Polyurethane products mainly include the following types: foam plastics, elastomers, fiber plastics, fibers, leather shoe resins, coatings, adhesives and sealants, among which foam plastics account for the largest proportion, and polyurethane raw materials need to be produced by polyurethane foaming machines Foaming, after foaming, it will form a sticky polyurethane raw material, which is as gray as dough. The dough needs to be heat-preserved and shaped. [0003] Acoustic panels are a type of tile that acts on sound insulation. There are sound insulation of buildings and sound insulation of structures. There are many types of sound insulation panels on the market, among which polyurethane sound insulation panels are one of them. Polyurethane panels have good sound i...

Problems solved by technology

[0007] In view of the problems in the prior art, the purpose of the present invention is to provide a polyurethane sound-insulating board production process, which solves the problem of polyurethane raw materials used to make polyurethane sound-insulating boards. The polyurethane raw materials need to be heat-preserved and shaped during the process of forming polyurethane sound-insulating boards. Currently, polyurethane raw materials are prone to uneven heating, resulting in different foam sizes inside polyurethane raw materials, which affect the sound insulation effect of polyurethane sound insulation boards.
