Abstract
Description
Technical Field
[0001] This utility model relates to the field of thermal insulation materials technology, and in particular to a new type of thermal insulation template for buildings. Background Technology
[0002] With the advancement of national "dual-carbon" energy conservation and the improvement of building energy efficiency standards, the fire resistance requirements for external wall insulation materials are becoming increasingly stringent. In particular, the requirement of "non-combustible" is put forward for external wall insulation materials of high-rise buildings and public buildings. At the same time, due to the large uncertainties in on-site construction, the traditional "adhesive" and "anchor" external wall insulation systems often experience peeling off of the insulation materials. There is an urgent market demand for an insulation material that can achieve "non-combustible" performance while also possessing good bending resistance, compressive strength, and impact resistance, which can be used as a formwork that does not need to be removed during concrete pouring, thus achieving "integrated wall insulation".
[0003] The commonly used Class A exterior wall insulation materials on the market include the following:
[0004] Rock wool board: Made from basalt and other raw materials, it is processed by high-temperature melting. It has the advantages of fire resistance, heat insulation, sound absorption and convenient construction. It is used for heat insulation, sound insulation and fire prevention and noise reduction of building walls, roofs and other structures.
[0005] Glass wool: It is made by fiberizing molten glass and adding binders. It has a large number of air pores, which can keep the heat insulated, absorb sound and reduce noise. It is an ideal material for steel structure building applications.
[0006] Foam glass: Made from various raw materials such as crushed glass through multiple processes, it has many superior properties such as heat insulation, sound absorption, moisture resistance, and fire resistance. It is a stable building heat insulation, sound insulation, and waterproof material.
[0007] Foam ceramic board: Made from clay tailings and other raw materials, it is produced by high-temperature firing using special processes and foaming technology. It features fire resistance, flame retardancy, anti-aging, eco-friendliness, good compatibility with the substrate, safety and stability, and can last as long as the building.
[0008] Currently, existing Class A exterior wall insulation materials are subject to factors such as thermal expansion and contraction, rainwater erosion, and external impacts. As a result, the materials cannot bond effectively, leading to low overall strength. Because of this low strength, they are difficult to use as formwork for concrete pouring and cannot withstand the large impact forces during concrete pouring. Utility Model Content
[0009] To address the shortcomings of existing technologies, this utility model provides a new type of thermal insulation template for buildings, which solves the problems of low strength, easy cracking, and difficulty in withstanding large impacts of existing "non-combustible" thermal insulation materials for exterior walls.
[0010] To achieve the above objectives, this utility model provides the following technical solution:
[0011] A novel thermal insulation template for construction includes a concrete base, an inner interface layer fixedly connected to one side of the concrete base, an inner reinforcing layer fixedly connected to the side of the inner interface layer away from the concrete base, an intermediate layer fixedly connected to the side of the inner reinforcing layer away from the inner interface layer, an outer reinforcing layer fixedly connected to the side of the intermediate layer away from the inner reinforcing layer, and an outer interface layer fixedly connected to the side of the outer reinforcing layer away from the intermediate layer.
[0012] Preferred: The intermediate layer is composed of polyol, lightweight fine aggregate, foaming agent, catalyst, polymeric isocyanate, lightweight ceramic particles and fly ash cenospheres, etc. The intermediate layer uses polyol as the main base material, and adds flame retardant, lightweight fine aggregate, foaming agent, catalyst, etc. to form component B. Polymeric isocyanate (component A) is used as curing agent. Components A and B are mixed in a certain proportion. Lightweight aggregate such as lightweight ceramic particles and fly ash cenospheres are used as component C. The mixture of A and B is then strongly stirred and mixed with component C. Components A and B react to generate polyurethane foam. The foam expands, fills and wraps and bonds the lightweight aggregate. After curing, it forms an A2 grade non-combustible intermediate layer.
[0013] Preferably, the inner reinforcing layer includes a reinforced glass fiber mesh, both sides of which are wrapped with polyurethane foam, and the inner reinforcing layer is bonded to the intermediate layer and the inner interface layer through the polyurethane foam.
[0014] Preferably, the outer reinforcing layer comprises basalt fiber mesh cloth, both sides of which are wrapped with polyurethane foam. The outer reinforcing layer is bonded to the intermediate layer and the outer interface layer through the polyurethane foam. The intermediate layer comprises an outer layer and an inner layer. The outer layer of the intermediate layer is more than 50 mm thick and is made of A2-grade non-combustible material with a thickness of more than 50 mm. The inner layer is made of flame-retardant or non-combustible polyurethane foam. The 50 mm thick outer layer can play a fireproof isolation role. The polyurethane foam of the inner and intermediate layers is formed at the same time as the non-combustible layer, which has good adhesion, can better improve the thermal insulation, and reduce the weight of the thermal insulation material.
[0015] Preferably, the inner interface layer includes fiberglass mat, both sides of which are coated with polymer cement, and the inner interface layer is bonded to the concrete substrate and the inner reinforcing layer by the polymer cement.
[0016] Preferably, the outer interface layer includes fiberglass mat, both sides of which are coated with polymer cement. The outer interface layer is fixedly bonded to the outer reinforcing layer by the polymer cement, and the outer interface layer is bonded to the outer decorative layer by the polymer cement.
[0017] Compared with the prior art, the present invention has the following beneficial effects:
[0018] I. The intermediate layer uses polyol as the main base material, mixed with flame retardants, lightweight fine aggregates, foaming agents, catalysts, etc. (component B). Polyisocyanate (component A) is used as a curing agent. Components A and B are mixed in a certain proportion. Lightweight ceramic particles, fly ash cenospheres, and other lightweight aggregates are used as component C. The mixture of components A and B is then vigorously stirred and mixed with component C. Components A and B react to generate polyurethane foam. The foam expands, fills, wraps, and bonds the lightweight aggregates. The foam intermediate layer has the advantages of light weight, good flame retardancy, filling, and wrapping properties. At the same time, a small amount of polyurethane resin expands and foams to a large volume, and the foam can bond a large volume of lightweight aggregates, making the intermediate layer "non-combustible". It also has good integrity and strength, ensuring that the material is not prone to problems such as aggregate falling off or delamination during use. This solves the problems of low strength and easy cracking of existing external wall insulation materials. The polyurethane foam of the inner intermediate layer is formed at the same time as the non-combustible layer, which has good adhesion, can better improve the insulation performance, and reduce the weight of the insulation material.
[0019] II. The inner and outer reinforcing layers mainly use reinforced fiberglass mesh, basalt fiber, and other inorganic fiber mesh as reinforcing materials. The mesh is wrapped inside and outside by polyurethane foam. The reinforced fiberglass mesh, basalt fiber, and other inorganic fiber mesh have high strength and toughness, which can effectively improve the load-bearing capacity of the overall structure, enhance tensile and tear resistance, and make the material more robust and durable, not easily damaged by external forces. This gives the application the advantages of high strength and high toughness. Fiberglass and basalt fiber themselves have good flame retardancy, and both inorganic fiber mesh and polyurethane foam have certain anti-corrosion and anti-aging capabilities, giving the application excellent fire resistance and the advantages of corrosion resistance and anti-aging.
[0020] Third, the inner and outer interface layers are mainly non-combustible felt, preferably polymer cement-based coated fiberglass felt or other non-combustible felt, which can bond well with other adjacent structural layers, making the connection between each layer tighter, effectively avoiding problems such as delamination and debonding, ensuring the integrity and stability of the entire structure, and at the same time having non-combustible properties, which can improve the fire safety performance of the material. In the event of a fire, it can prevent the spread of fire, reduce the fire risk, provide better protection for people and property, and further enhance the fire resistance of this application.

[0024] This application provides a novel building insulation template that effectively solves the problems of existing "non-combustible" exterior wall insulation materials having low strength, being prone to cracking, and not being able to withstand large impacts.
[0025] Example
[0026] like Figure 1 As shown, the technical solution in this application embodiment effectively solves the technical problems of existing "non-combustible" thermal insulation materials for exterior walls having low strength, being prone to cracking, and not being able to withstand large impact forces. The overall idea is as follows:
[0027] To address the problems existing in the prior art, this utility model provides a novel thermal insulation template for buildings, including a concrete base 6. An inner interface layer 4 is fixedly connected to one side of the concrete base 6. An inner reinforcing layer 2 is fixedly connected to the side of the inner interface layer 4 away from the concrete base 6. An intermediate layer 1 is fixedly connected to the side of the inner reinforcing layer 2 away from the inner interface layer 4. An outer reinforcing layer 3 is fixedly connected to the side of the intermediate layer 1 away from the inner reinforcing layer 2. An outer interface layer 5 is fixedly connected to the side of the outer reinforcing layer 3 away from the intermediate layer 1.
[0028] Intermediate layer 1 is composed of polyol, lightweight fine aggregate, foaming agent, catalyst, polymeric isocyanate, lightweight ceramic particles and fly ash cenospheres. Intermediate layer 1 uses polyol as the main base material, and adds flame retardant, lightweight fine aggregate, foaming agent, catalyst and other additives to form component B. Polymeric isocyanate (component A) is used as a curing agent. Components A and B are mixed in a certain proportion. Lightweight aggregates such as lightweight ceramic particles and fly ash cenospheres are used as component C. The mixture of components A and B is then vigorously stirred and mixed with component C. Components A and B react to generate foam. The foam expands, fills and wraps and bonds the lightweight aggregate. After curing, intermediate layer 1 is formed.
[0029] The inner reinforcing layer 2 includes a reinforced fiberglass mesh, both sides of which are wrapped with polyurethane foam. The inner reinforcing layer 2 is bonded to the intermediate layer 1 and the inner interface layer 4 through the polyurethane foam. The intermediate layer 1 includes an outer layer and an inner layer. The outer layer of the intermediate layer 1 is thicker than 50 mm and is made of A2-grade non-combustible material thicker than 50 mm. The inner layer is made of flame-retardant or non-combustible polyurethane foam. The 50 mm thick outer layer can play a fireproof isolation role. The polyurethane foam of the inner intermediate layer 1 and the 50 mm thick outer non-combustible layer are formed at the same time, which has good adhesion, can better improve the thermal insulation, and reduce the weight of the thermal insulation material.
[0030] The outer reinforcing layer 3 includes a basalt fiber mesh cloth, both sides of which are wrapped with polyurethane foam. The outer reinforcing layer 3 is bonded to the intermediate layer 1 and the outer interface layer 5 through the polyurethane foam.
[0031] The inner interface layer 4 includes fiberglass mat, both sides of which are coated with polymer cement. The inner interface layer 4 is bonded to the concrete substrate 6 and the inner reinforcing layer 2 by the polymer cement. The polymer cement is a composite material made by mixing organic polymers (such as latex, resin, etc.) with cement, aggregates (sand, stone, etc.) and additives in a certain proportion.
[0032] The outer interface layer 5 includes fiberglass mat, both sides of which are coated with polymer cement. The outer interface layer 5 is fixedly bonded to the outer reinforcing layer 3 by polymer cement, and the outer interface layer 5 is bonded to the outer decorative layer by polymer cement.
[0033] Working principle:
[0034] First, the intermediate layer 1 uses polyol as the main base material, and adds flame retardant, lightweight fine aggregate, foaming agent, catalyst, etc. to form component B. Polyisocyanate (component A) is used as the curing agent. Components A and B are mixed in a certain proportion. Lightweight ceramic particles, fly ash cenospheres and other lightweight aggregates are used as component C. The mixture of components A and B is then vigorously stirred and mixed with component C. Components A and B react to generate polyurethane foam. The foam expands, fills, wraps and bonds the lightweight aggregate. The foam intermediate layer 1 has the advantages of light weight, good flame retardancy, filling and wrapping properties. At the same time, a small amount of polyurethane resin expands and foams to a large volume, and the foam can bond a large volume of lightweight aggregate, making the intermediate layer 1 "non-combustible". It also has good integrity and strength, ensuring that the material is not prone to problems such as aggregate falling off or delamination during use, thus extending the service life of the material.
[0035] Secondly, the inner reinforcing layer 2 and the outer reinforcing layer 3 mainly use reinforced fiberglass mesh, basalt fiber, and other inorganic fiber mesh as reinforcing materials. The mesh is wrapped inside and outside by polyurethane foam. The reinforced fiberglass mesh, basalt fiber, and other inorganic fiber mesh have high strength and toughness, which can effectively improve the load-bearing capacity of the overall structure, enhance tensile and tear resistance, and make the material more robust and durable, and less prone to damage from external forces. This gives the application the advantages of high strength and high toughness. Fiberglass and basalt fiber themselves have good flame retardancy, and both inorganic fiber mesh and polyurethane foam have certain anti-corrosion and anti-aging capabilities, giving the application excellent fire resistance and the advantages of anti-corrosion and anti-aging.
[0036] Third, the inner interface layer 4 and the outer interface layer 5 are mainly non-combustible felt, preferably polymer cement-based coated fiberglass felt or other non-combustible felt, which can bond well with other adjacent structural layers, making the connection between each layer tighter, effectively avoiding problems such as delamination and debonding, ensuring the integrity and stability of the entire structure, and at the same time having non-combustible properties, which can improve the fire safety performance of the material, prevent the spread of fire in the event of a fire, reduce the risk of fire, and provide better protection for people and property.
[0037] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
