A kind of preparation method of biomass energy storage thermal insulation tile

Abstract

The preparation method of a biomass energy-storing heat-insulating tile and belongs to the field of building material preparation. The preparation method includes: using pig leaf lard as a raw material; using alkaline water for saponification after stewing; adding acid for reduction to obtain mixed lard mixed fatty acid; mixing the mixed lard mixed fatty acid with dodecanol, shearing, and emulsifying; using an emulsion to soak expanded perlite to obtain an energy-storing filler, adding other raw materials, and pressing to form the biomass energy-storing heat-insulating tile. Bio-oil is used as a raw material to prepare a fatty acid organic solid-liquid phase change material, and expanded perlite is used for loading, so that the defect that fatty acid solid-liquid phase change materials are prone to leakage when in use and prone to oxygenolysis and volatilization at high temperature is overcome; the phase change material is utilized to absorb heat of sunlight for solid-liquid phase change so as to automatically adjust environment temperature, the defect of high energy consumption caused by using air conditioners is made up, and the biomass energy-storing heat-insulating tile is a new product which is environment-friendly and energy-saving.

Description

technical field [0001] The invention relates to a preparation method of a biomass energy storage thermal insulation tile, which belongs to the field of building material preparation. Background technique [0002] Tile is an essential basic component of human housing, its role is to prevent rain and heat insulation, it can withstand the sun and rain for many years without damage. However, ordinary tiles are not very ideal in terms of heat insulation effect, especially in summer when they are directly exposed to the hot sun, and the indoor temperature can reach more than 40 degrees, which is more than ten degrees different from the room temperature of the lower floor. Therefore, the residents living on the top floor are subjected to high temperature steaming day and night in summer. In winter, due to the thin roof and poor thermal insulation performance, it will be tested by severe cold again, so people hope that a sunshade and thermal insulation device can be added on the ro...

Problems solved by technology

[0005] The technical problems mainly solved by the present invention are as follows: ordinary tiles have single functions, unsatisfactory heat insulation effect and poor heat preservation performance, which lead to high indoor temperature in summer and low temperature in winter, and the use of air conditioners to adjust room temperature consumes a lot of energy, which is not necessary. In line with the current situation of modern life concepts of energy saving and environmental protection, a preparation method of biomass energy storage heat insulation tiles is provided

The invention uses bio-oil as a raw material to prepare fatty acid organic solid-liquid phase change material, mixes it into tile slurry to make heat-insulating tiles, and uses expanded perlite to load the phase change material, which solves the problem of fatty acid-based solid-liquid phase change materials. It is easy to leak during use, prone to oxidative decomposition and volatilization at high temperatures, and the phase change material doped in the tile is used to absorb the heat of sunlight, and a solid-liquid phase transition occurs to store the heat and prevent heat from penetrating through the tile. When the indoor temperature is raised, the temperature drops at night, and the heat stored during the day can be released to prevent the indoor temperature from being too low at night, thereby achieving the purpose of controlling the ambient temperature and saving energy, and making up for the lack of a large amount of energy consumption caused by the use of air conditioners. A new product that is environmentally friendly and energy-saving
