Preparation method of PVC aerogel co-agent foam board

Abstract

The invention discloses a preparation method of a PVC aerogel co-agent foam board, and belongs to the field of architectural decoration. The PVC aerogel co-agent foam plate comprises a core material layer, bonding layers and metal layers are sequentially arranged on the upper surface and the lower surface of the core material layer, the core material layer is a PVC aerogel co-agent foam plate, themetal layers are aluminum alloy sheets, and the bonding layers are thermite composite polymer films. According to the embodiment of the invention, the core material layer which is the PVC aerogel co-agent foam plate is arranged between the two metal layers which are the metal sheets, and the foaming glass plate and the metal sheets are bonded together through the polymer films, so that the fireproof performance of the composite board can be greatly improved, and the fireproof grade of the composite board is improved. Not only the flame retardance can be improved, and also the thermal insulation, the waterproof and moisture-proof properties and the sound absorption and noise reduction effects can be improved.

Description

technical field [0001] The invention relates to the field of architectural decoration, in particular to a preparation method of a PVC airgel co-agent foamed board. Background technique [0002] Composite panels are mainly composed of three parts: core material, adhesive and metal. Among them, most of the composite panels currently on the market are mainly aluminum-plastic composite panels, which are widely used in various architectural decorations and daily necessities. However, the existing aluminum-plastic composite panels have problems such as poor flame retardancy and fire prevention performance because the core material is made of plastic. Although, after years of research and development, a variety of flame-retardant polyethylene plastic products have appeared on the market, but due to the upper limit of the flame-retardant ability of polyethylene, the fire rating of the aluminum-plastic composite panels produced can only be upgraded to B-level at most. Therefore, it...

Problems solved by technology

However, the existing aluminum-plastic composite panels have problems such as poor flame retardancy and fire prevention performance because the core material is made of plastic.

Although, after years of research and development, a variety of flame-retardant polyethylene plastic products have appeared on the market, but due to the upper limit of the flame-retardant ability of polyethylene, the fire rating of the aluminum-plastic composite panels produced by it can only be upgraded to Class B at most. Therefore, it cannot meet the requirements of domestic and foreign building fire protection ratings.

[0003] In addition, although in the prior art, inorganic materials such as palm environmental boards are used as the core material of the composite board to improve the fireproof performance of the composite board, but the composite board has problems such as poor thermal insulation performance and noise reduction performance, so it is still Need to improve the existing composite board
