Abstract
A fireproof coating for an aluminum alloy structure of a prefabricated building includes the following components, in parts by weight: 30 to 60 parts of a reinforcing glue A, 80 to 150 parts of an adhesive, 4 to 6 parts of a rheological agent, 5 to 20 parts of zinc borate, 10 to 30 parts of modified expanded vermiculite, 0 to 3 parts of cellulose, 2 to 3 parts of a reinforcing agent, 5 to 20 parts of a low-temperature foaming aid, and 200 to 300 parts of a solvent. The reinforcing glue A includes 5 to 10 parts of polyvinyl alcohol (PVA), 50 to 100 parts of ammonia solution, and 5 to 20 parts of a modifier. The new f1reproof coating, when heated by flame, forms a nonflammable foamed carbonized layer with a three-dimensional structure before its temperature reaches the thermal limit of aluminum alloy. The skeleton of the foamed carbonized layer effectively protects the aluminum alloy from high temperature and meets requirements of the RABT temperature rise mode.
Description
-1-
TECHNICAL FIELD The present invention relates to the technical field of fire prevention, and in particular to a fireproof coating for an aluminum alloy structure of a prefabricated building.
BACKGROUND Fire prevention is essential. It is also necessary to ensure the safety of persons and properties. Fire prevention can be achieved by numerous technical means, such as fireproof materials and coatings. Fireproof coatings have been widely used because they are convenient to use and have broad application, including the application to building materials such as steel and aluminum and their alloys common to the industry. Compared with steel materials, aluminum alloy materials have lower high temperature resistance.
Toimprove the heat resistance and fire resistance of aluminum alloys, a fireproof coating should be able to form a foamed carbonized layer at a low temperature while meeting requirements of the RABT temperature rise mode.
SUMMARY The present invention aims to provide a fireproof coating for an aluminum alloy structure of a prefabricated building. The fireproof coating forms a foamed carbonized layer in advance at a low temperature, which effectively protects aluminum alloy material structures and allows the fireproof coating to meet requirements of the RABT temperature rise mode.
In order to achieve the above objective, the present invention adopts the following technical solutions: The present invention provides a fireproof coating for an aluminum alloy structure of a prefabricated building, including the following components, in parts by weight: 30 to 60 parts of a reinforcing glue A, 80 to 150 parts of an adhesive, 4 to 6 parts of a rheological agent, 5 to 20 parts of zinc borate, 10 to 30 parts of modified expanded vermiculite, 0 to 3 parts of cellulose, 2 to 3 parts of a reinforcing agent, 5 to 20 parts of a low-temperature foaming aid, and 200 to 300 parts of a solvent. The reinforcing glue A includes 5 to 10
-2- parts of polyvinyl alcohol (PVA), 50 to 100 parts of ammonia solution, and 5 to 20 parts of a modifier.
Specifically, the adhesive may be a rapid hardening Portland cement.
Further, the rheological agent may be hydrogenated castor oil and PVA fiber; and the hydrogenated castor oil and PVA fiber have a weight ratio of 1:1. Further, the low-temperature foaming aid may be one of ammonium cyanate, urea, a uracil compound, a cucurbituril compound, a diarylurea compound, and a naphthoylurea compound, or a mixture of two or more thereof in any ratio.
Further, the solvent may be water.
Further, the reinforcing agent may be chopped glass fiber yarn.
Further, the modifier may be a mixture of ammonium sulfate, sodium bisulfite and sodium borate in a weight ratio of 1:1:1. Specifically, a preparation method of the reinforcing glue may include the following steps: SI: adding 5 to 10 parts of PVA to 100 parts of water, and stirring a resulting mixture for dissolution to obtain a component A for later use; S2: taking another 100 parts of water and heating to 40°C to 50°C; adding 50 to 100 parts of the ammonia solution, and thoroughly mixing; adding 5 to 20 parts of a mixture of ammonium sulfate, sodium bisulfite and sodium borate in a weight ratio of 1:1:1 while stirring; and conducting reaction for 30 min to 60 min to obtain a component B; and S3: mixing the component A obtained in step S1 and the component B in step S2, and stirring a resulting mixture for 30 min to 60 min; and adding water to 1,000 parts by weight to obtain the reinforcing glue A.
Compared with the prior art, the present invention has the following beneficial effects: (1) In the present invention, PVA is adopted as the main film-forming material, and modifiers such as ammonium sulfate, sodium bisulfite and sodium borate are added to impart relative flexibility and adhesion to the coating, so that the coating can still tightly bind to a substrate under the action of explosion waves.
Hydrogenated castor oil, PVA fiber, cellulose and the like are used to improve the rheological properties and the film- forming efficiency in construction of the coating.
Sodium borate and zinc borate are added so that the coating can react with phosphorus or silicon-containing substances in the coating under the conditions of heating and carbonization to form a soft or liquid substance, which expands and increases the strength of the carbonized layer.
And one of
-3- ammonium cyanate, urea, a uracil compound, a cucurbituril compound, a diarylurea compound, and a naphthoylurea compound, or a mixture of two or more thereof in any ratio 18 added so that the coating can expand at a low temperature to increase the carbonized layer, thus effectively protecting aluminum alloy materials from being affected by excessive-high temperatures. Through reasonable compatibility of materials, the present invention ensures various functional performances of the coating under normal conditions and enhances the toughness and ductility of the fireproof coating. The fireproof coating, when burned in a flame, forms the material basis of a non-flammable foamed carbonized layer with a three-dimensional (3D) structure before its temperature reaches the thermal limit of aluminum alloy. The skeleton of the foamed carbonized layer effectively protects an aluminum alloy structure from high temperature and meets the requirements of the RABT temperature rise mode.
(2) The modified expanded vermiculite in the present invention has a pressure-relief function and exhibits a strong affinity for a substrate, which can effectively ensure the pressure relief in an explosion, reduce damage of a pressure to the fireproof coating, and further strengthen the fireproof performance of the fireproof coating.
DETAILED DESCRIPTION THE EMBODIMENTS The present invention will be further described below in conjunction with description of drawings and examples, but the implementation of the present invention includes but is not limited to the following examples.
The present invention provides a fireproof coating for an aluminum alloy structure of a prefabricated building, which can expand to form a carbonized layer at a low temperature on the premise of meeting the RABT temperature rise mode, thus effectively protecting the aluminum alloy structure of the prefabricated building. The fireproof coating specifically includes the following component, in parts by weight: 30 to 60 parts of a reinforcing glue A that includes 5 to 10 parts of PVA, 50 to 100 parts of ammonia solution, and 5 to 20 parts of a modifier. The modifier may be a mixture of ammonium sulfate, sodium bisulfite and sodium borate in a weight ratio of 1:1:1.
The coating of the present invention further includes: 80 to 150 parts of rapid hardening Portland cement, 4 to 6 parts of a mixture of hydrogenated castor oil and PVA fiber in a weight ratio of 1:1, 5 to 20 parts of zinc borate, 10 to 30 parts of modified expanded vermiculite, 0 to 3 parts of cellulose, 2 to 3 parts of chopped glass fiber yarn, and 200 to
-4- 300 parts of water.
Moreover, the coating is also added with 5 to 20 parts of one of ammonium cyanate, urea, a uracil compound, a cucurbituril compound, a diarylurea compound, and a naphthoylurea compound, or a mixture of two or more thereof in any ratio, so as to reduce the foaming carbonization temperature of the coating.
In the present invention, a preparation method of the reinforcing glue A may include the following steps: S1: adding 5 to 10 parts of PVA to 100 parts of water, and stirring a resulting mixture for dissolution to obtain a component A for later use; S2: taking another 100 parts of water and heating to 40°C to 50°C; adding 50 to 100 parts of the ammonia solution, and thoroughly mixing; adding 5 to 20 parts of a mixture of ammonium sulfate, sodium bisulfite and sodium borate in a weight ratio of 1:1:1 while stirring; and conducting reaction for 30 min to 60 min to obtain a component B; and S3: mixing the component A obtained in step S1 and the component B in step S2, and stirring a resulting mixture for 30 min to 60 min; and adding water to 1,000 parts by weight to obtain the reinforcing glue A.

The reinforcing glue A was prepared as follows: 6.5 parts of PVA were added to 100 parts of water, and a resulting mixture was stirred to obtain a component A; another 100 parts of water were taken and heated to 40°C, and then added with 80 parts of ammonia solution; 15 parts of a mixture of ammonium sulfate, sodium bisulfite and sodium borate were added under stirring, and reaction was conducted for 30 min to obtain a component B; and the component A was mixed with the component B, a resulting mixture was stirred for 30 min, and water was added to 1,000 parts to obtain the reinforcing glue A.
Experiments verified that, when the fireproof coating was applied to a steel material substrate, and the substrate was applied in a simulated tunnel fire scene, the temperature during the simulation increased to 1,200°C within 5 min, maintained at 1,200°C for 1.5 h, and then rapidly reduced for 1.83 h.
In a simulated environment meeting the RABT
-5- temperature rise mode, the substrate coated with the fireproof coating in this example did not significantly deform under the action of 100 kilograms of force, and the fireproof coating began to foam at 353°C to form a foamed carbonized layer with a 3D structure.
