Energy-saving heat insulation material applied to buildings and preparation method thereof

Abstract

The invention discloses an energy-saving heat insulation material applied to buildings. The energy-saving heat insulation material is prepared from the following raw materials in parts by weight: 45-55 parts of waste coal residue, 5-10 parts of graphene sponge, 20-30 parts of magnesium-aluminum spinel, 5-10 parts of hollow glass microspheres, 10-20 parts of non-asbestos mineral fiber, 10-20 partsof manila hemp fiber, 5-10 parts of cryptand ionic salt fireproof heat insulation functional additives and 2-5 parts of coupling agent. The invention also discloses a preparation method of the energy-saving heat insulation material applied to buildings. The preparation method comprises the following steps: mixing all the raw materials according to a ratio to obtain a mixed material; feeding the mixed material into a ball milling tank; carrying out ball milling treatment for 3-6 hours; then adding water into the mixed powder, wherein the mass of the water is equal to the mass of the raw materials; uniformly stirring to obtain slurry; then injecting the slurry into a mold; putting the mold and the mixed slurry in a curing furnace; naturally cooling and demolding after finishing curing to obtain the heat insulation material. The energy-saving heat insulation material applied to the buildings is lower in cost, higher in fireproof performance, more obvious in heat preservation and insulation effect, lower in heat conduction coefficient, wider in usage temperature range, higher in adhesion capability and higher in resistance to quick cooling and quick heating, and is more environmentallyfriendly.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a building energy-saving thermal insulation material and a preparation method thereof. Background technique [0002] In recent years, with the development of the economy and the growth of the global population, energy issues have become one of the important factors restricting social development. Advocating the life philosophy of "energy saving, low carbon, and environmental protection" is one of the important ways to solve this problem. This life philosophy is an inherent requirement for adjusting the economic structure and changing the mode of economic development. Strategic options for circular economy. my country has the largest construction market in the world, and the energy consumption of buildings has become the top of all kinds of energy consumption. How to reduce the energy consumption of buildings is an urgent problem to be solved in the industry. [0003]...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a building energy-saving thermal insulation material and a preparation method thereof. The preparation method is simple and easy, has low requirements on equipment, easy-to-obtain raw materials, convenient post-processing, low price, and is suitable for large-scale production; the prepared Building energy-saving thermal insulation materials overcome the high cost of existing traditional thermal insulation materials, poor fire protection rating, difficult construction, poor bonding ability, easy to fall off, and poor wind pressure resistance, impact resistance, poor thermal insulation effect, pollution of the environment, etc. Defects, compared with the energy-saving and heat-insulating materials in the prior art, the energy-saving and heat-preserving materials for buildings disclosed in the present invention are cheaper, more environmentally friendly, have stronger fire resistance, more significant heat preservation and heat insulation effects, lower thermal conductivity, and a wider operating temperature range. Wider, stronger bonding ability, better resistance to rapid cooling and rapid heating
