Composite energy-saving self-insulation external wall boards made from building residues and industrial waste residues and production methods thereof

Abstract

The invention discloses composite energy-saving self-insulation external wall boards made from building residues and industrial waste residues and production methods of the energy-saving self-insulation external wall boards. The invention provides production formulations of three composite energy-saving self-insulation external wall boards which are made from building residues and industrial waste residues and have different thickness ranges, and provides production methods of the external wall boards. According to the composite energy-saving self-insulation external wall boards made from building residues and industrial waste residues and the production methods of the external wall boards, wall body material and heat insulation material are combined together and subjected to one-step production molding; the external wall boards can be produced in a mechanically automatic production line; the composite energy-saving self-insulation external wall boards made from building residues and industrial waste residues which take multiple waste residues as main raw materials of the external wall body material and take agricultural wheat straw, crop straw and other waste ash residues as external wall body heat insulation material are developed, thus recycling waste materials and protecting the environment and saving energy. The products are capable of resisting vibration, compression, impact, freezing, weathering, corrosion and aging, good in wear resistance, free from toxicity, harmless, capable of absorbing moisture and water, and good in expansion contractility; in addition, the products are simple in formulation, low in cost and higher in cost performance.

Description

[0001] The original application for this sub -case was: 2008.7.4, the application number: 200810045462.x, the patent name is: composite built -up industrial waste residue energy -saving self -insulation outer wall board and its production method. Technical field [0002] The present invention involves the technology field of environmental protection building materials. Specifically, it involves a compound built -in industrial waste residue energy -saving spontaneous insulation outer wall board and its production method. Background technique [0003] With the development of the times, people's requirements for work and life have improved, so the requirements for environmental protection and energy saving performance of the building materials themselves are getting higher and higher.Several categories of exterior wall insulation materials used on the market such as concrete insulation mortar, polybine insulation mortar, wave -based microfin insulation mortar, polybenzene foam insula...

AI Technical Summary

Problems solved by technology

Several major types of exterior wall insulation materials currently on the market, such as concrete insulation mortar, polystyrene insulation mortar, corrugated microbead insulation mortar, polystyrene foam insulation board and polystyrene extruded insulation board stickers, etc., although these materials have certain thermal insulation performance, but most of them do not meet the material standards of building construction regulations. First, the materials do not have fire protection performance. The processing and use of materials have not been treated with fire protection. In case of fire, they will burn rapidly and emit a large amount of harmful gases and smoke. A serious threat to people's life safety; the second is that the installation and construction methods of the above-mentioned external wall insulation materials are all attached to the surface of the completed external wall body by methods such as coating, wiping, pasting, and sticking, which is difficult to control and ensure the quality of the insulation layer materials. and life expectancy, and will bring many potential safety hazards. Third, the external wall insulation materials made of organic materials are expensive and difficult to popularize and apply.

[0004] The utilization of industrial waste residues such as fly ash, slag and tailings slag and the utilization of waste straw in agricultural production are very important issues. The above wastes have become land occupation and waste of resources.
