Flame-retardant protective plastic plate

Abstract

The invention discloses a flame-retardant protective plastic plate. The flame-retardant protective plastic plate comprises a flame-retardant layer of an upper layer, a high-temperature-resistant layer of an intermediate layer and a heat insulation layer of a lower layer, wherein the flame-retardant layer is connected with the high-temperature-resistant layer through a high-temperature-resistant bonding agent; the high-temperature-resistant layer is connected with the heat insulation layer through the high-temperature-resistant bonding agent; the flame-retardant layer is a polyphenylether plastic plate layer; the high-temperature-resistant layer is a polysulfone plastic layer; the heat insulation layer is a polypropylene plastic layer; and the high-temperature-resistant bonding agent is thermoplastic polyimide resin. Due to the adoption of the flame-retardant layer made of polyphenylether plastics, the effects of flame retarding and self-extinguishing can be achieved effectively; the flame-retardant protective plastic plate has outstanding mechanical strength; the polysulfone plastic has the performance of high-temperature resistance and high mechanical strength; good effects of high-temperature resistance and heat insulation can be achieved; the polypropylene plastic has high-temperature resistance and high mechanical strength; through the polysulfone plastic high-temperature-resistant layer, a heat insulation effect can be achieved effectively; and moreover, the flame-retardant protective plastic plate consists of plastics, so that the cost is low and the service life is long.

Description

technical field [0001] The invention relates to a plastic product, in particular to a flame-retardant protective plastic board. Background technique [0002] Due to the great danger of fire, the flame retardant problem has long been paid attention to by people, and the application of high molecular polymers has been popularized in various fields of the national economy, such as electrical cables, building materials, aviation parts, etc. all require flame retardant. [0003] The fire and flame retardant version can avoid the occurrence of fire or reduce the loss of fire. , the current fireproof board has low strength and can only be used for decoration and decoration, and cannot be used as a furniture board, while fiberboard, particle board or wood plank can be used as a furniture board but is not flame retardant. Existing fire and flame retardant plates are slightly insufficient in terms of strength, toughness, fire and flame retardancy, and acid and alkali resistance, and ...

AI Technical Summary

Problems solved by technology

, the current fireproof board has low strength and can only be used for decoration and decoration, and cannot be used as a furniture board, while fiberboard or particle board or Xi wood board can be used as a furniture board but is not flame retardant.

Existing fire-resistant and flame-retardant plates are slightly insufficient in terms of strength, toughness, fire-resistance, acid and alkali resistance, etc., and cannot have one or more functions, or have multiple functions but the manufacturing cost is relatively high, and cannot be widely used
