Problems solved by technology

The reflective coating has a high reflectivity to solar heat, so it has a cooling function. However, because the reflective coating belongs to a polymer resin film, it is easy to age and has poor weather resistance.
[0007] Chinese patent CN101293789A discloses a preparation method of a high solar reflection heat insulation material, which is characterized in that ceramics are used as the substrate, and metal paint is applied as a heat reflection coating. The preparation method belongs to the secondary coating method, but due to the The method needs to clean the ceramic substrate, the process is cumbersome, and the bonding strength is easily affected

Abstract

The invention relates to a solar heat reflective heat insulating and preserving foaming ceramic material and a manufacturing method thereof, belonging to the field of the preparation of an energy-saving ceramic material. The manufacturing method comprises the following steps of: preparing a closed pore ceramic matrix by adding an amount of low-cost minerals to industrial wastes such as coal gangues, pulverized fuel ash and the like, compounding a solar heat reflecting layer composed of inorganic materials in situ in the preparation process, and carrying out primary sintering to obtain a heat insulating and preserving integrated material which has ideal heat insulating and preserving performance, noise reduction performance and the like. The invention combines the solar heat reflection function, the structural functions of porous materials and the heat transfer and noise reduction characteristics of porous materials, and the manufactured foaming ceramic material has smaller heat transfer coefficient, higher solar heat reflectivity, favorable corrosion prevention and high-temperature resistance and excellent mechanical properties, weather resistance and sound insulation performance.Besides, the process of the manufacturing method is simple, procedures can be adjusted easily, and materials are easy to acquire, thereby facilitating application and popularization.

Description

【Technical field】 [0001] The invention relates to the technical field of energy-saving ceramic materials and their manufacture, in particular to a solar heat reflection, heat-insulation and thermal insulation foaming ceramic material and a manufacturing method thereof. 【Background technique】 [0002] At present, the growth rate of energy consumption in the world far exceeds the growth rate of population, energy crisis, CO 2 Emissions, global warming and other issues are all related to energy consumption. Therefore, the requirements for energy conservation and emission reduction in countries around the world are increasing day by day. [0003] Among all energy consumption, building energy consumption accounts for a high proportion of the total energy consumption of society. At present, in western developed countries, building energy consumption generally accounts for 30% to 45% of the total social energy consumption, and it also accounts for 20% to 25% in my country. Theref...
