Novel preparation technique of energy conservation material for buildings

Abstract

The invention discloses a novel preparation technique of an energy conservation material for buildings. The energy conservation material for buildings is obtained by mixing expanded perlite, cement and a gelation additive, wherein the expanded perlite is prepared by using the technique comprising the following steps of: uniformly enabling the perlite ore sand to flow through a sand frying furnace using a feeding control device, preheating the perlite ore sand to 250-350 DEG C, inputting the preheated perlite ore sand to a gas furnace, heating to ensure that the perlite ore sand is rapidly expanded to obtain the expanded perlite, and controlling the outflow amount of the expanded perlite to convey partial expanded perlite to the sand frying furnace to form hot sand reflow heat supply, so that the heat energy of the partial expanded perlite can be used for uniformly and circularly preheating the perlite ore sand flowing in the sand frying furnace to cause all the perlite ore sand to reach the preheating temperature to be expanded to form the expanded perlite. The energy conservation material for buildings prepared by using the novel preparation technique disclosed by the invention not only has the characteristics of light weight, environmental-friendliness, and efficient thermal insulation, but also is environment-friendly, capable of realizing A-grade fire resistance, convenient to construct, unlikely to absorb water, expand, crack and fall off, high in durability, and long in service life.

Description

technical field

[0001] The invention relates to heat insulation and energy-saving materials for buildings, in particular to a preparation process for a new type of building energy-saving material with light weight, environmental protection, high heat insulation and A-level fireproof performance. Background technique

[0002] With the acceleration of the urbanization process and the continuous improvement of people's quality of life, building energy consumption has exceeded one-third of the total energy consumption of the society, and has become a huge burden on the national economy. It is one of the important links to set goals and maintain sustainable economic development. Comprehensive building energy conservation is conducive to fundamentally promoting the conservation and rational use of energy resources, alleviating the contradiction between the supply of energy resources and economic and social development in our country; it is conducive to accelerating the development...

Embodiment Construction

[0008] The preparation method of the new building energy-saving material, it is mainly made of dry mortar by mixing expanded perlite, cement and gelling additives, etc. Rock, 5-10 wt% cement and 3-5 wt% gelling additives), when in use, add appropriate amount of water to mix to make building energy-saving materials (mortar), and then plaster the exterior walls and roof surfaces. The expanded perlite is produced by the following process; the expanded perlite is produced by using the existing expanded perlite production line, which is mainly composed of a natural gas puffing furnace, a cooling furnace, a sand frying (preheating) furnace and a dust removal device , using this production line, the perlite ore raw material is first added to the sand frying furnace for preheating, and then transported to the puffing furnace to be puffed at a high temperature of 1100 ℃, and then it can be made into expanded perlite after cooling. Use the perlite ore feeding control device (screw drive...
