Abstract

The invention discloses a light flame-retardant insulation board for a building external wall and a preparation method thereof. The light flame-retardant insulation board is prepared from high-density polyethylene, a coupling agent, a foaming agent, aramid fibers, phenolic resin and a refractory through raw material mixing, frame building and pouring, capsule making and fixing, ventilation and foaming, sealed coating and drying formation. The high-density polyethylene is used as a main raw material, the aramid fibers and the phenolic resin are added, the aramid fibers and the phenolic resin have the excellent performance of ultrahigh strength, high modulus, high temperature resistance and the like, and the high temperature resistance of the heat preservation plate can be effectively improved; and in addition, the flame-retardant layer is arranged on the heat preservation plate, and the fire-resistant agent is added into the flame-retardant layer, so that the fire can be prevented from burning; flame-retardant bags are additionally arranged in the flame-retardant plate, and carbon dioxide and water can be released by the flame-retardant bags in the flame-retardant plate if fire disasters, and combustion explosion and the like occur, so that fire extinguishing effects can be effectively realized, and personal safety can be better protected.

Description

technical field [0001] The invention relates to the technical field of flame-retardant thermal insulation boards, in particular to a lightweight flame-retardant thermal insulation board for building exterior walls and a preparation method thereof. Background technique [0002] The thermal insulation board is a plastic board made of polyethylene as raw material plus other raw and auxiliary materials. Adding a flame retardant to it can make it have flame retardant properties and be suitable for use in many special occasions; [0003] The existing flame-retardant insulation boards cannot achieve a good flame-retardant effect in the event of a fire. When a large fire or explosion occurs, personal safety cannot be well guaranteed, and the production efficiency is low, and the production line occupies a large area. Contents of the invention [0004] The purpose of the present invention is to provide a light-weight flame-retardant insulation board for building exterior walls and...
