A production and processing technology of polyurethane sound insulation board

Abstract

The invention provides a polyurethane sound-insulating board manufacturing process, which relates to the technical field of sound-insulating materials. The polyurethane sound-insulating board manufacturing process is completed by a polyurethane sound-insulating board manufacturing and processing device. The polyurethane sound-insulating board manufacturing and processing device includes a horizontally placed Workbench, the top middle part of the workbench is provided with a raised heat preservation box, the heat preservation box is a square structure, and the top middle part of the heat preservation box is provided with a square structure molding cavity; the present invention molds the polyurethane sound insulation board from the During the ejection process from the inside of the cavity to the top of the insulation box, the chip storage tanks set up at equal intervals on the inner wall of the molding cavity, the edge of the polyurethane sound insulation board will pass through the top of the chip storage tank towards the bottom surface of the inner wall of the molding cavity. The corner burrs are scraped off to reduce the corner burrs on the surface of the polyurethane sound insulation board removed after molding, so that the surface of the polyurethane sound insulation board removed after molding 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...

AI Technical Summary

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.
