Description
Technical Field
The invention relates to the technical field of covering or lining made of organic plastics with or without reinforcements or filling materials, in particular to a heat reflection aerogel PET composite heat insulation board and a preparation method thereof.
Background
Aerogel is a novel heat insulation material, and the heat insulation effect is far better than that of other types of heat insulation materials. The pore inside the aerogel is an open pore, and the pore diameter is 20-50 nanometers. Aerogel products on the market exist mainly in the form of aerogel powder and aerogel felt.
Foamed PET panels, i.e. building panels made of foamed polyester plastic. The raw materials are widely available and can be waste mineral water bottles, so that the effect of waste utilization is achieved. And different from other building heat insulation materials, the foaming PET plate has good mechanical strength and can be used as a stress member.
However, the foamed PET sheet itself has a very difficult disadvantage to overcome, in that it is difficult to connect with other building materials:
And (3) organic adhesive connection: due to the chemical nature of the foaming PET plate, the adhesive film formed by the aqueous organic adhesive and the foaming PET plate cannot be effectively combined, and the adhesive film and the foaming PET plate are separated from each other after being solidified; oily organic adhesives can cause corrosion to the foamed PET sheet.
And (3) cement mortar connection: the bonding between the foamed PET plate and the cement mortar is very weak, and the adhesive force is less than 0.1 megapascal.
And (3) inorganic adhesive connection: the inorganic adhesive has better adhesive force than cement mortar, but the connection is very easy to lose efficacy, and after other building components are adhered to the foaming PET plate by using the inorganic adhesive, the inorganic adhesive can be expanded with heat and contracted with cold or repeatedly pulled for a plurality of times, and then the inorganic adhesive falls off.
And (3) mechanical connection: the mechanical connectors such as bolts are difficult to seal in holes (gaps exist around the holes) after penetrating the foamed PET sheet, because conventional materials for sealing building boards are also adhesive or cement mortar in nature. If the foamed PET plate is used on the outer wall of a building, the mechanical connection may cause water leakage of the building.
For the above reasons, the existing foamed PET board is greatly limited in application, and the subsequent use scenes such as building wallboard, which need decoration or electromechanical construction on the board, are not suitable for using the foamed PET board.
Disclosure of Invention
The invention provides a heat reflection aerogel PET composite heat-insulating board and a preparation method thereof.
The technical problems to be solved are as follows: the foamed PET board is difficult to connect with other building materials and is not suitable for application in subsequent use scenarios requiring decoration or electromechanical construction on the board.
In order to solve the technical problems, the invention adopts the following technical scheme: the heat reflection aerogel PET composite heat insulation board comprises a foaming PET substrate and aerogel modified layers coated on two side board surfaces of the foaming PET substrate, wherein an anti-cracking net for preventing cracks of the aerogel modified layers from being prolonged is buried in the aerogel modified layers;
the aerogel modified layer is an inorganic adhesive doped with aerogel powder and is in a bendable foaming material state.
Further, the aerogel-modified layer has an infrared reflectance of not less than 0.85.
Further, the inorganic adhesive is a silicate adhesive.
Further, the aerogel powder is silica aerogel powder.
Further, the closed cell ratio of the foamed PET substrate is not less than 85%.
Further, the anti-cracking net is basalt gridding cloth or carbon fiber gridding cloth.
A preparation method of a heat reflection aerogel PET composite heat insulation board is characterized by comprising the following steps: the aerogel PET composite heat-insulating plate for preparing the aerogel PET composite heat-insulating plate convenient for subsequent construction comprises the following steps of:
step one: stirring and mixing the aerogel powder and the inorganic adhesive;
Step two: coating an inorganic adhesive containing aerogel powder on the upper plate surface of a horizontally-laid foamed PET substrate to form an aerogel modified layer, paving an anti-cracking net on the aerogel modified layer, and strickling to enable the anti-cracking net to be embedded into the aerogel modified layer;
step three: and (3) after the aerogel modified layer is solidified, turning over the foaming PET substrate and repeating the second step to finish coating on the two side plate surfaces of the foaming PET substrate.
In the first step, the aerogel powder and the inorganic adhesive are mixed under the working condition of constant temperature or temperature reduction, and ultrasonic treatment is not needed in the mixing process, so that the air in the aerogel powder is not replaced by the inorganic adhesive.
Compared with the prior art, the heat reflection aerogel PET composite heat insulation board and the preparation method thereof have the following beneficial effects:
in the present invention, the inventors found that when other building members are connected to a foamed PET substrate by an inorganic adhesive, the connection is liable to fail because the inorganic adhesive (both of silicate adhesive and phosphate adhesive) is poor in ductility after curing and is liable to break after receiving a shearing force in a direction perpendicular to a glue film, whereas the foamed PET substrate is inferior in rigidity to steel or concrete, and is not effective in resisting deformation when the building members adhered to the foamed PET substrate by the inorganic adhesive are pulled, thereby causing the glue film of the inorganic adhesive to break by the shearing force. Meanwhile, the thermal deformation difference between the inorganic adhesive and the foamed PET substrate serving as a foaming material is large, and when the inorganic adhesive expands with heat and contracts with cold, the adhesive film of the inorganic adhesive can bear huge temperature stress to crack and fall off.
Based on the finding, the inventor adds aerogel powder into the inorganic adhesive to form a foaming material, so that the ductility of the adhesive film is greatly improved, the adhesive film is not easy to break when bearing shearing force, the thermal deformation is consistent with that of the foaming PET substrate, and the cracking and falling off caused by large difference of the thermal deformation are avoided. And by adding the anti-cracking net, even if the adhesive film cracks, the crack is difficult to continue to develop. The two are effectively connected with the foaming PET substrate, the foaming PET substrate is wrapped in the foaming PET substrate, the subsequent building construction can be performed on the aerogel modified layer, and the problem that the subsequent construction is difficult due to difficult connection or corrosion of the foaming PET substrate is solved. Meanwhile, the aerogel also improves the heat preservation effect of the foaming PET substrate.
The composite heat-insulating plate adopts the combined action of the binder and the fiber net, so that the rigidity of the plate is enhanced, and the plate has the structural stress capability. Meanwhile, the aerogel modified layer has the advantages of fire resistance, water resistance, mildew resistance and infrared reflectivity of more than 0.85 (the inventor discovers that the inorganic adhesive has an infrared reflection effect after being mixed with aerogel powder) and also has a reinforcing effect on the foaming PET substrate. The fire resistance and strength of the composite heat-insulating board are improved, the composite heat-insulating board has double effects of heat insulation and heat reflection, and the thermal resistance R value of the composite board is superior to that of the foamed PET substrate. The combination of the above points ensures that the composite heat-insulating plate can meet various requirements of building walls/floors such as stress, heat insulation, sound insulation and the like with extremely light weight and extremely thin thickness, and can achieve some unprecedented brand new effects when applied to the building, such as the building walls which are fixed on the light steel keels by gluing completely, such as an ultra-thin and ultra-light floor heating system.

Detailed Description
As shown in fig. 1-2, a heat reflection aerogel PET composite heat insulation board comprises a foaming PET substrate 1 and aerogel modified layers 2 coated on two side plate surfaces of the foaming PET substrate 1, wherein an anti-cracking net 3 for preventing cracks of the aerogel modified layers 2 from extending is buried in the aerogel modified layers 2;
the aerogel modified layer 2 is an inorganic adhesive doped with aerogel powder and is in a bendable foaming material state.
If the aerogel-modified layer 2 is a foamed material, the thermal deformation amount is consistent with that of the foamed PET substrate 1, and the ductility thereof is significantly improved. In practical application, the aerogel modified layer 2 does not fall off even if the composite heat-insulating board is repeatedly trampled by constructors, and the composite heat-insulating board can be firmly hung no matter the composite heat-insulating board is used for attaching ceramic tiles, attaching line boxes, brushing cement mortar, brushing various coatings, attaching wallpaper and attaching decorative boards. The surface texture of the aerogel modified layer 2 is similar to that of ground glass, is a flat and quite rough surface, and can be firmly combined with cement mortar without roughening or scraping.
It is very difficult to make the inorganic adhesive into a foamed material directly connected to the foamed PET substrate 1. The existing inorganic adhesive, whether silicate adhesive or phosphate adhesive, cannot exist stably after being paved into a thin layer, and can escape before solidification.
However, if the powder itself with bubbles (because the adhesive film can only hold the lower powder) is doped into the inorganic adhesive to form the foaming material as in the present invention, it is also difficult and heavy. In practice, it was found that closed cell powders were doped into the inorganic binder and floated to the surface. The open-celled powder is doped into the inorganic adhesive, and although the floating to the surface is improved, the bubbles inside the mixture are replaced by the inorganic adhesive during the mixing process, and the effect is poor. The inventor has found after many attempts that, because the pores in the aerogel powder are very small, after the stirring condition is controlled, the bubbles in the aerogel powder can be ensured not to be replaced by the inorganic adhesive in the mixing process.
The infrared reflectance of the aerogel-modified layer 2 is not lower than 0.85. The infrared reflectivity of the aerogel powder is changed differently by different inorganic adhesives, so that the addition amount of the aerogel powder needs to be adjusted according to the actual situation, thereby changing the infrared reflectivity. Generally, the more aerogel powder is added, the higher the infrared reflectance.
In this embodiment, the inorganic binder is a silicate binder and the aerogel powder is silica aerogel powder. In this combination, the forces between the two are great and the floating can be effectively resisted during the mixing process. At the same time, the combination can be firmly combined with cement mortar (of course, the combination can also be firmly combined with other adhesives, but the cement mortar is most commonly used in building).
In this example, the closed cell ratio of the foamed PET substrate 1 was not less than 85%. The foamed PET substrate 1 is required to have a sufficient waterproof effect if it is to be used as a building exterior wall panel, and thus a closed cell ratio is required here to ensure a sufficient waterproof effect.
The anti-cracking net 3 is basalt gridding cloth or carbon fiber gridding cloth, and the materials can be firmly combined with the inorganic adhesive.
The preparation method of the heat reflection aerogel PET composite heat insulation board is used for preparing the heat reflection aerogel PET composite heat insulation board and comprises the following steps of:
step one: stirring and mixing the aerogel powder and the inorganic adhesive;
Step two: coating an inorganic adhesive containing aerogel powder on the upper plate surface of a horizontally-arranged foaming PET substrate 1 to form an aerogel modified layer 2, wherein the thickness of the aerogel modified layer 2 can be controlled by a toothed scraper;
Then paving an anti-cracking net 3 on the aerogel modified layer 2 and strickling to enable the anti-cracking net 3 to be embedded into the aerogel modified layer 2;
step three: and (3) after the aerogel modified layer 2 is solidified, turning over the foamed PET substrate 1 and repeating the second step, so that the two side plate surfaces of the foamed PET substrate 1 are coated.
In the first step, the aerogel powder and the inorganic adhesive are mixed under the working condition of constant temperature or temperature reduction, and ultrasonic treatment is not needed in the mixing process, so that the air in the aerogel powder is ensured not to be replaced by the inorganic adhesive. The formula of the inorganic adhesive and the aerogel powder ensures that the aerogel powder cannot float upwards. And the condition in the stirring process is controlled to avoid the bubbles in the aerogel powder from being replaced. Here, unlike the pores in the catalyst particles, the substance in the pores in the aerogel powder is air, which is not compatible with the inorganic binder. Meanwhile, as the pores are small enough, the air in the inorganic adhesive can be prevented from entering as long as the air cannot come out. Therefore, by controlling the temperature during the stirring process, the air is prevented from expanding and escaping from the aerogel powder due to the rising temperature. Meanwhile, ultrasonic vibration needs to be avoided, ultrasonic stirring is an efficient stirring mode, but air in aerogel powder can be driven out when the ultrasonic stirring mode is applied.
The composite insulation board in the embodiment has prepared a sample and is sent to be inspected, and the detection unit is as follows: the national detection pilot-operated group Beijing Limited company, the national building material industry building material and the structural safety quality supervision and inspection center.
The test results show that the adhesion between the foamed PET substrate 1 and the aerogel modified layer 2 exceeds 0.6 mpa, and the requirement of ceramic tile can be met by reaching 0.35 mpa.
Meanwhile, the composite heat-insulating board (thickness is 12 mm) in the embodiment has the surface density of 2.5 kg per square meter, the gypsum board surface density of paper with the same thickness is 8.7 kg per square meter, the glass fiber high-strength gypsum board surface density with the same thickness is 10 kg per square meter, and the PET composite board surface density is 1/3-1/4 of that of the two gypsum boards, but the performances of structural strength, heat-insulating effect and the like are higher.
In addition, the thermal conductivity of the aerogel heat reflection PET composite board is lower than that of the foaming PET substrate 1 with the same thickness, and the heat preservation effect is better.
The above examples are only illustrative of the preferred embodiments of the present invention and are not intended to limit the scope of the present invention, and various modifications and improvements made by those skilled in the art to the technical solution of the present invention should fall within the scope of protection defined by the claims of the present invention without departing from the spirit of the present invention.
