High-strength light-weight environment-friendly building material and preparation method thereof

Abstract

The invention provides a high-strength light-weight environment-friendly building material and a preparation method thereof, relating to the field of novel environment-friendly building materials. Thehigh-strength light-weight environment-friendly building material is prepared from the following raw materials: building sand, low-alkalinity cement, polystyrene , sulphoaluminate, wollastonite, light-weight magnesium oxide, expanded perlite, light-weight ceramics, nano silicon dioxide, hydroxypropyl methyl cellulose, calcium formate, glass fiber, wood fiber, polyester fiber, honeycomb bamboo charcoal fiber, a high temperature resistant binder, a magnesium chloride aqueous solution, a foaming agent, a water reducing agent and water. The environment-friendly building material prepared by the invention is good in fire resistance, light in weight, good in heat preservation effect, energy-saving, environment-friendly, easy to prepare, convenient to construct, compact in texture and good in thermal insulation and sound insulation effects, and can simultaneously meet the building needs of exterior walls and interior walls, thereby having broad market prospects.

Description

technical field [0001] The invention relates to the field of novel environment-friendly building materials, in particular to a high-strength, light-weight environment-friendly building material and a preparation method thereof. Background technique [0002] Energy saving and environmental protection have become a major issue that human beings must face in the 21st century, and it has also become an important issue that our construction industry must focus on solving. Improving the thermal insulation performance of houses is an important measure for building energy saving and consumption reduction. Under the advocacy of the state, many new buildings and many old buildings are applying thermal insulation layers on the outer walls and inner walls to reduce energy consumption. To achieve the effect of heat insulation in the house, that is, to prevent heat radiation from being transmitted to the house through the heat insulation material of the inner and outer walls in hot summer...

AI Technical Summary

Problems solved by technology

Among them, the main advantages of organic material boards are low density, high heat preservation efficiency, and good toughness. The disadvantages are poor fire resistance, easy to ignite after fire, and will produce toxic smoke during the combustion process, which seriously endangers life safety, and also has aging resistance. Defects such as poor performance, short service life, complicated installation procedures, and high cost

The advantages of inorganic material thermal insulation layer are: low cost, flame retardant, no smoke generated during fire, good aging resistance, same lifespan as the building, easy installation, low cost, etc. The disadvantage is that it will increase the overall cost of the building. Weight, material lack of toughness
