Description
Technical Field
The invention belongs to the field of building materials, and particularly relates to a foamed glass insulation board for a building and a preparation method of the foamed glass insulation board.
Background
With the increasing development of energy crisis, domestic attention is paid to energy-saving management of building materials more and more, the promotion of building material energy conservation becomes an important development direction for building low-carbon economy, realizing energy conservation and emission reduction and maintaining sustainable development of social economy. The external wall thermal insulation belongs to a main embodiment form of energy-saving building materials, and the existing external wall thermal insulation materials mainly comprise three main categories of organic thermal insulation materials, inorganic thermal insulation materials, organic and inorganic composite thermal insulation materials and the like.
Foam glass insulation boards are inorganic environment-friendly insulation board materials which rise in recent years, and are formed by adopting cullet as a material to perform a specific foaming process. According to Baidu encyclopedia, the foam glass insulation board was invented by Petzburg Corning company in America at the earliest, and is an inorganic composite insulation board which is mainly prepared by finely crushing and uniformly mixing broken glass, a foaming agent (generally silicon carbide), a modified additive, a foaming promoter and the like, and then melting at high temperature, foaming and annealing. The foam glass insulation board has the advantages of heat preservation, fire prevention, corrosion resistance, sound insulation and the like, so the foam glass insulation board is widely applied to the fields of petroleum, chemical engineering, underground engineering, national defense and military industry and the like, and is also widely applied to the fields of civil buildings such as civil building outer walls and roofs.
However, when the foam glass insulation board is applied to the civil building field, the foam glass insulation board adopts silicon carbide as a foaming agent, so that the cost is high, and the broken glass is adopted as a raw material for foaming, so that the problem of uneven distribution of bubbles easily exists, and the quality of a finished product of the foam glass insulation board is inevitably influenced. In order to solve the technical problem, the invention patent with publication number CN107721182A discloses a method for preparing foam glass, which uses graphite powder as a foaming agent, mixes with pretreated glass powder, and then fires to obtain a foam glass product. However, in the method, graphite powder (the particle size of the raw material is usually not more than 20 microns) is used as a foaming agent, so that the addition is difficult, the effect requirement of uniform mixing with glass powder through ball milling is strict, the batch stability of the obtained foam glass insulation board is poor, quality control is difficult to carry out in actual batch production, and the defects of low surface strength, poor crack resistance and poor durability exist in the obtained foam glass insulation board by simply using the glass powder as the raw material and using the graphite as the foaming agent; meanwhile, the conventional glass insulation board is sintered at high temperature, a large amount of energy is consumed, the manufacturing cost of the foamed glass insulation board is high, and the technical development direction of energy conservation and low-carbon management of building materials is not facilitated.
For the technical current situation, based on the research and development experience of the inventor in the field of building materials and accumulated theoretical knowledge, a large number of practical application cases are verified, and finally the technical scheme of the application is provided to improve the technical problems.
