Full-solid waste cementing material, thermal insulation material, and processing method and application of thermal insulation material

Abstract

The invention discloses a full-solid waste cementing material, a thermal insulation material, and a processing method and an application of the thermal insulation material, and belongs to the construction field. The full-solid waste cementing material includes the following micro-powder raw materials by the mass percentage: 30-70% of mineral slag micro-powder, 10-40% of steel slag micro-powder, 5-15% of desulfurized gypsum, 10-30% of fly ash, and 1-5% of silica powder. The full-solid waste cementing material can be used as a main material of an inorganic thermal insulation material. The full-solid waste cementing material is composed of mineral slag, steel slag, desulfurization gypsum, fly ash and other solid wastes. Through rational proportioning of all the components, all the componentscan react synergistically with each other. A foamed thermal insulation board prepared from the full-solid waste cementing material has the characteristics of A-class non-flammability, good thermal insulation effect and low cost, can be applied to external wall thermal insulation technology with large quantity. The problem that organic thermal insulation materials are flammable and expensive, and inorganic rock wool is harmful to a human body, has high water absorption rate and needs to be repaired for many times are solved.

Description

technical field [0001] The invention relates to the construction field, in particular to an all-solid waste gelling material, its thermal insulation material, its processing method and its application. Background technique [0002] At present, when building new energy-saving buildings and retrofitting existing buildings in my country, expanded polystyrene (EPS), extruded polystyrene (XPS) and polyurethane foam (PU) are often used as external insulation for external walls, especially in cold and severe cold regions. The preferred insulation material in the system. Although the above-mentioned materials have many advantages such as light weight, heat insulation, and easy processing, their fatal disadvantage is that they are flammable. In the event of a fire, the fire will spread rapidly and produce a large amount of toxic smoke, making it difficult to fight. Let the projects using these materials become "indefinite time bombs" for people's lives and property. [0003] On Marc...

Problems solved by technology

At present, the traditional non-combustible inorganic thermal insulation material in the market is rock wool. Rock wool is an inorganic thermal insulation material. However, during the production and construction of rock wool, rock wool will have tiny fibers flying out. If it is inhaled, it will damage the respiratory tract. , workers who have been exposed to rock wool for a long time will cause different degrees of pneumoconiosis, and serious cases will cause cancer; if it enters the eyes of workers, the chances of workers suffering from conjunctivitis and keratitis will greatly increase, and severe cases can see corneal opacity and local abscesses

In addition, rock wool is also likely to cause skin allergies to workers, causing contact dermatitis

During the use of rock wool, its water absorption rate is high, and water is easy to accumulate in the rock wool board, which will increase the weight of the insulation layer for a long time, causing the insulation layer to fall off, and the repair rate is high
