Abstract

The invention discloses a non-combustible heat preservation wall material and a manufacturing method thereof. According to the invention, natural kieselguhr, sericite powder, mineral fibre, silica sand, surface active agent, materials with special functions and other inorganic materials are manufactured into a functional environment-friendly heat insulation and heat preservation wall material through the steps of calcining fusion, foaming molding, winnowing pelleting, dehumidification drying and the like. The material not only has the characteristics of small density, no combustion, no combustion supporting, heat insulation, heat preservation, environment protection and the like, but also has the special functions of decomposing formaldehyde, ammonia and other harmful gases, resisting bacterium, preventing mildew and the like. The material can be manufactured into putty to be coated on the surface of a building, the inner wall of a boiler, a metal storage tank and a pipeline surface, and can also be directly pressed into plates to be applied for building surface decoration. The thermal conductivity of the material is less than 0.2W / (M.K), and the material can resist the high temperature of 1200 DEG C.

Description

(1) Technical field [0001] The invention relates to building decoration, fire prevention, thermal insulation materials and applications thereof. (2) Background technology [0002] In my country, building wall surface materials are mainly based on polymer synthetic resin emulsion coatings, which have been widely used due to their excellent decorative effects and decorative protection properties, but their thermal insulation capabilities are limited, especially organic polymer resins. The content is relatively high, and the fire resistance is average. Some high-end residences or special houses such as concert halls and movie theaters will use inorganic natural diatomite compounded with an appropriate amount of binder to directly scrape the wall. Due to the complex construction conditions and difficult process of diatomite, the water resistance is average. , so that the application of diatomite materials has been greatly restricted. [0003] Since the "Eleventh Five-Year Plan"...
