And fifthly, the innovation of the construction process of the heat-insulating material.
The technical route and effects of the non-combustible insulation board of the invention are specifically described as follows
The wall heat-insulating material has the following properties:
the wall heat-insulating material is provided with: the energy-saving, safe, fireproof, green, environment-friendly, healthy, low-carbon, long in service life, never falling off, free of secondary pollution when encountering fire, capable of recycling solid waste, free of building garbage, low in comprehensive cost of buildings, excellent in comprehensive physical and chemical properties and the like.
The basic physical and chemical properties of the wall thermal insulation material are as follows:
first, heat preservation performance:
as a known technique, there are three types of heat energy transfer: one is convection, the other is radiation, and the other is conduction. A base material, blocking any form of heat transfer, has an insulating form of the material, which becomes an insulating material.
Air is the best insulation material in nature in terms of its performance. The data for any insulating material is not scientific if it is lower than the thermal conductivity of air. As for the wall heat-insulating material, the heat conduction capability of the wall heat-insulating material is reduced, the heat conductivity coefficient of the material is reduced, the heat-insulating property of the material is improved, the consumption of energy is reduced, and the purpose of energy conservation is achieved. The functions of radiation and convection cannot be embodied in wall materials and heat-insulating materials.
The main technical indexes of the heat-insulating and energy-saving material are the heat conductivity coefficient of the material.
The main technical index of the coating energy-saving material is the heat transfer coefficient of the material.
The main technical index of the heat storage energy-saving material is the heat storage coefficient of the material.
Second, waterproof and anticorrosive properties:
water and air are sources of life. In nature, air and water are ubiquitous and are the basic conditions of physical and chemical reactions of all materials.
The waterproof and anticorrosive properties of the material are not absolutely separable. Under certain conditions, all substances are unchanged and do not react if no water or air is present. Therefore, when moisture invades the material, the water content of the material exceeds a critical index, and the material can mildew along with the change of weather, thereby influencing or losing various functions, and if any medium of water or air is isolated, the waterproof and anticorrosion effects of the material can be achieved.
The waterproof function and the waterproof function of the thermal insulation material are enhanced, the volume water absorption rate is effectively reduced (the water absorption rate must reach about 3 percent, less than 5 percent and more than 2 percent), and the problem of frost heaving and thaw collapse of the wall material and the thermal insulation material can be thoroughly solved. Meanwhile, the problem of air permeability of wall materials and heat-insulating materials needs to be solved, micro air permeability and impermeability are achieved, and the bonding strength between the materials is effectively guaranteed. The three points are achieved, and the weather resistance, the aging resistance, the bonding firmness and the service life of the wall material and the heat-insulating material are effectively guaranteed. The wall material and the heat insulation material can have the same service life as the building.
Third, fireproof performance:
the combustion of materials is a complex thermal oxidation reaction process. The basic elements of combustion include: combustible materials, oxygen, temperature and heat transfer process and the like. The material will not burn when any one of the links is blocked.
The invention relates to a green low-carbon energy-saving environment-friendly T-series non-combustible heat-insulation board, which is characterized in that: the novel heat-insulating material has heat-insulating property, fireproof property, comprehensive and reasonable properties and mutual consideration. The heat-insulating material thoroughly eliminates fire hazards in the production, transportation, storage and construction processes of the heat-insulating material, effectively improves the heat-insulating property of the heat-insulating material, and greatly enhances the physical and chemical properties such as compressive strength, tensile strength, breaking strength, positive and negative wind load resistance, bonding strength, waterproof property, water resistance, weather resistance, freeze thawing resistance, aging resistance and the like.

The green, low-carbon, energy-saving and environment-friendly T-series non-combustible heat-insulating board heat-insulating material has excellent comprehensive performance and is a green, environment-friendly and energy-saving A-level fireproof heat-insulating material.
The independent technical innovation points of the green, low-carbon, energy-saving and environment-friendly T-series non-combustible insulation board product are as follows:
1) and the design structure is innovative:
a green, low-carbon, energy-saving and environment-friendly T-series non-combustible insulation board product is prepared by taking polystyrene foaming particles with high-efficiency heat preservation and relatively stable physical and chemical properties as a tire mold carrier and T-series innovative T-series multifunctional adhesive cement as a filling material, and forming a wrapping layer on the surface of each polystyrene particle to form an independent fireproof isolation film through a stirring synthesis process, so that each polystyrene foaming particle has an independent fireproof function and a special fireproof isolation film technology is formed; meanwhile, the organic polystyrene particle monomer raw material is subjected to molecular copolymerization modification, so that the organic heat-insulating material, the inorganic bonding material and the inorganic flame-retardant material have the same polarity, and the heat-insulating material, the bonding material and the flame-retardant material have the same polarity affinity, so that effective bonding is performed, and finally the obtained product is placed into a mold box for molding, curing and forming.

The particle isolation fireproof technology and the thermosetting technology of the green, low-carbon, energy-saving and environment-friendly T-series non-combustible insulation board product are explained as follows:
1. particle isolation fire prevention technology:
mixing T series innovative multifunctional T series innovative viscous glue paste originally invented by the company into viscous soup bases, then soaking polystyrene foam particles, and forming a fireproof isolation film on the surface of each polystyrene heat-preservation particle by using a microphase composite technology; each polystyrene heat-insulating particle with excellent heat-insulating property has the functions of fire prevention and flame retardance, and then a plurality of polystyrene heat-insulating particles are sent into a die box to be pressed and are bonded into blocks; and cutting the plate into plates with different specifications and thicknesses according to the requirements of different geographical environments on heat insulation coefficients.
2. Thermosetting technology:
the fireproof isolation film formed on the surface of each polystyrene heat-preservation particle unit generates phase change under the attack of flame or high temperature, and a continuous closed-pore honeycomb fireproof isolation bin can be quickly formed. The fire-proof isolation bin has the functions of isolating oxygen and preventing flame from spreading. On the other hand, further conduction of heat is effectively blocked. When high-temperature flame attacks, only the polystyrene particles exposed on the surface layer are subjected to thermal shrinkage, combustion and gasification, the melting and dripping phenomena are avoided, the curling deformation phenomenon and the heat-insulating material collapse phenomenon are avoided, and the fireproof heat-insulating material has an excellent fireproof function.
Fourth, anti-drop adhesive property:
any monomer material molecule, which has its own cohesive force, is very strong (in the same gas phase). If the composite materials, especially organic materials and inorganic materials are needed to be bonded together to form integrity, firstly, positive and negative nuclear ions on the surfaces of two or more materials need to be matched, so that the positive and negative nuclear ions have the same polarity and the same absorption property and cannot mutually repel each other, and certain chelating force and holding force are needed to form homohetero crosslinking. The positive and negative ions of the bonding mortar and the heat insulating material are balanced, mutually penetrated and coordinated and cannot be rejected. The structural composition of the material has the same internal and external polarities, is not mutually exclusive, and is a key composition factor for ensuring that the heat insulation material, the wall material and the facing material are prevented from falling off and the same service life is achieved. Meanwhile, the components are mutually permeated into the interior of each other molecule to generate a physical and chemical reaction to form a net structure with certain cohesive strength, so that the adhesive force of the composite material can be greatly enhanced.
The invention relates to a nano chelating bonding technology of T series innovative multifunctional viscous-resistance adhesive paste, which comprises the following steps:
the innovative T-series innovative multifunctional viscous cement utilizes a micromolecular nano chelating bonding technology to bond an inorganic chelating bonding material with a building main body, a T-series non-combustible heat preservation plate and a decorative layer in an apposition manner, so that the nano chelating bonding material with super-strong permeability rapidly permeates, and the apposition material is rapidly condensed into a whole just like a crab clamp for catching a game. The novel binding material has a stable chelating structure, really realizes that the building main body, the heat-insulating material and the veneer layer are combined into a whole, effectively avoids the aging and falling of T-series innovative multifunctional adhesive-resistant mortar, and greatly prolongs the service life of the heat-insulating material, thereby realizing the same service life of the heat-insulating material and the veneer layer as the building main body.
