The invention relates to the technical field of building decoration and fire-proof materials, in particular to a fire-proof composite particleboard and a preparation method thereof. The core board consists of upper and lower two layers of high density board and core board sandwiched between two layers of high density board; the core board is composed of glass magnesium board and fire-proof particleboard; the glass magnesium board is made of magnesium oxide, magnesium chloride, magnesium sulfate and fly ash; and the fire-proof particleboard is made of particles and vermiculite. The fire-proof composite particleboard of the invention can not only increase its overall strength by 5 to 10 times on the original basis, but also does not contain any oxidizable and burnable substances, and does not produce smoke and other organic poisons at high temperature. It also has the functions of moisture-proof, water-proof, heat insulation, sound insulation and other functions. At the same time, the fire-proof composite particleboard has good extensibility and decoration such as spraying paint, sticker, drillability, sawability, planeability and so on. It can be used as fire-proof door core, high-grade kitchenware, furniture and other purposes, adapted to various climatic conditions.

一种防火复合刨花板及其制备方法
本专利技术涉及建筑装饰、防火材料
,具体地说,涉及一种防火复合刨花板及其制备方法。
技术介绍
随着建筑行业的崛起,高层建筑的增多,随之而来在消防安全上也出现了新的问题,同时,人们对居住环境的要求越来越高,室内装饰板、可拆装家具等室内装修材料的防火性能也亟需进一步的提高。目前,室内装修墙体常用的材料主要有墙面砖、木夹板、密度板以及壁纸等材料,家具、厨具常用的材料主要有木夹板、密度板以及三合板等材料。虽然这些材料的使用范围较广,具有很多优点,但均存在不能防火的缺陷。专利号为200720087740.9,名称为:玻镁、珍珠岩防火门芯板的技术专利,其夹芯板使用的是珍珠岩板,而珍珠岩在潮湿的状态下,吸水率高,易开裂,强度低,高温下会产生颗粒状物,危害人体健康。因此,珍珠岩的环保性差。专利号为:201310359723.6,名称为:一种膨化硅酸盐材料成型用无机胶粘剂及其制备方法的专利技术专利,该文献公开的是一种制备膨化蛭石防火保温板的新型环保材料,采用该环保材料制成的膨化蛭石防火保温板在工业与民用建筑中的应用非常广泛,可用于防火门芯、外墙 ...
