Description
Technical Field
The invention belongs to the field of waterproof coiled materials, and relates to a flame-retardant modified asphalt waterproof coiled material and a preparation method thereof.
Background
The waterproof coiled material is generally used for the top and the side parts of various buildings, and can effectively prevent outside water from penetrating and leaking into the buildings. At present, waterproof coiled materials in the market are various in variety and different in performance. From the base material of the waterproof roll, there are three main categories: high polymer plastic waterproof coiled materials such as PVC waterproof coiled materials, TPO waterproof coiled materials and the like; rubber waterproof coiled materials, such as butyl rubber waterproof coiled materials, ethylene propylene diene monomer rubber waterproof coiled materials and the like; modified asphalt waterproof coiled materials, such as SBS elastomer modified asphalt waterproof coiled materials, APP plastomer modified asphalt waterproof coiled materials and the like.
The modified asphalt waterproof coiled material, in particular the SBS elastomer modified asphalt waterproof coiled material has the advantages of low price of chromium, excellent waterproof performance, convenient construction and the like, and is the most commonly used waterproof material at present.
However, the common modified asphalt waterproof coiled material has a fatal defect of inflammability. The main material of the modified asphalt is still asphalt, and the asphalt is a flammable material, and on one hand, because the asphalt has high-temperature flowing property, the fire spreading is particularly easy to cause in the combustion process; on the other hand, asphalt also decomposes various flammable gases at high temperatures, which can further increase the fire. Therefore, research on flame-retardant modified asphalt waterproof coiled materials is very necessary.
The most direct method for improving the flame retardant property of the modified asphalt is to add a flame retardant into the modified asphalt. However, the effect of directly adding the conventional flame retardant into the modified asphalt waterproof coiled material is not ideal, and the flame retardant effect of the flame retardant can be negatively influenced by the high-temperature flowing property of asphalt.
Therefore, the invention aims to solve the problem of poor flame retardant property of the existing modified asphalt waterproof coiled material, and is expected to prepare the flame retardant modified asphalt waterproof coiled material.
Disclosure of Invention
In order to solve the problem of poor flame retardance in the existing modified asphalt waterproof coiled material, the invention provides a flame-retardant modified asphalt waterproof coiled material.
The flame-retardant modified asphalt waterproof coiled material has a five-layer structure, a base layer is arranged in the middle of the flame-retardant modified asphalt waterproof coiled material, an upper flame-retardant modified asphalt layer and a lower flame-retardant modified asphalt layer are respectively arranged on the upper side and the lower side of the base layer, and surface isolation layers are respectively arranged on the outer sides of the upper flame-retardant modified asphalt layer and the lower flame-retardant modified asphalt layer.
Wherein, the upper flame-retardant modified asphalt layer and/or the lower flame-retardant modified asphalt layer is prepared from the following raw materials in parts by mass: 55-75 parts of 90# asphalt, 10-15 parts of SBS modifier, 10-15 parts of softening oil, 5-10 parts of silane coupling agent and 3-8 parts of montmorillonite-based organophosphorus flame retardant.
Further, in order to ensure the flame retardant property of the modified asphalt waterproof coiled material of the present invention, the montmorillonite-based organic phosphorus flame retardant used in the present invention is prepared as follows.
(1) Dispersing montmorillonite powder in paraxylene solvent, adding concentrated phosphoric acid with concentration of 85%, and acid treating montmorillonite, wherein the ratio of montmorillonite to phosphoric acid is 100g: (300-800) ml, while there is a large amount of phosphoric acid surplus;
(2) Adding neopentyl glycol into the montmorillonite powder dispersion liquid after the acid treatment, uniformly stirring and heating to 140 ℃, and carrying out esterification reaction for 6-8h, wherein neopentyl glycol phosphate is formed on the surface of the montmorillonite powder after the acid treatment, and the mole ratio of the neopentyl glycol to the phosphoric acid is 1: (1.5-2.5);
(3) Keeping the temperature unchanged, further adding melamine into the solution after the esterification reaction, stirring, preserving the heat for 2-4h, forming neopentyl glycol phosphate melamine salt on the surface of montmorillonite powder,
(4) And then carrying out suction filtration and drying on the solution to obtain the montmorillonite-based organophosphorus flame retardant.
Further, the preparation method of the upper flame-retardant modified asphalt layer and/or the lower flame-retardant modified asphalt layer comprises the following steps:
adding 90# asphalt into a reaction kettle according to parts by weight, heating to 150 ℃, adding a silane coupling agent and softening oil, heating to 180 ℃ after stirring at a high speed for 15min, adding an SBS modifier, continuously stirring uniformly to obtain a molten mixture, adding a montmorillonite-based organophosphorus flame retardant, and shearing on a high-speed shearing machine for 90min to obtain uniformly dispersed flame-retardant modified asphalt; and then uniformly coating the obtained flame-retardant modified asphalt on the upper and lower surfaces of the tire base layer to obtain an upper flame-retardant modified asphalt layer and a lower flame-retardant modified asphalt layer.
Further, the prepared upper flame-retardant modified asphalt layer and the prepared lower flame-retardant modified asphalt layer are respectively coated with a surface isolation layer, so that the flame-retardant modified asphalt waterproof coiled material can be obtained.
Further, the softening oil is one selected from aromatic oil, naphthenic oil and naphtha.
Further, the silane coupling agent is selected from one or more of gamma-aminopropyl triethoxysilane, gamma-methacryloxypropyl trimethoxysilane, (3-aminopropyl) triethoxysilane, tri-tert-butoxyvinyl silane, gamma-ureido propyl triethoxysilane, N-methyl-3-aminopropyl trimethoxysilane and gamma-ethylenediamine triethoxysilane.
According to the invention, instead of the existing method for directly adding the flame retardant into the modified asphalt, the flame retardant is attached to the surface of montmorillonite powder in advance, and then the montmorillonite-based organophosphorus flame retardant is added into the modified asphalt, so that the dispersion uniformity of the flame retardant in the modified asphalt can be improved.
In the preparation process of the montmorillonite-based organophosphorus flame retardant, acid treatment is carried out on montmorillonite in advance, and hydrogen ions and sodium ions in the montmorillonite are replaced in the acid treatment process, so that the montmorillonite containing proton phosphoric acid can be obtained, and part of phosphate groups are ensured to be uniformly and firmly attached to the surface of montmorillonite powder. In the subsequent esterification reaction and the reaction with melamine, the obtained neopentyl glycol phosphate and neopentyl glycol phosphate melamine salt can be respectively ensured to be uniformly and firmly attached to the surface of montmorillonite powder.
The organic phosphorus flame retardant is used in the invention, and forms a crosslinked solid layer with stable structure after being heated, and the crosslinked solid layer covers the inflammable physical surface to isolate inflammable matters from external gas, thus preventing the combustion process from further happening. Although asphalt has high-temperature flowing property, fire spreading is easy to cause in the combustion process, flowing property of molten asphalt is hindered by inner filler powder montmorillonite, and the molten asphalt generally takes away the inner filler powder in the flowing and dripping processes, so that the distribution of the montmorillonite powder and the organophosphorus flame retardant attached to the surface in the whole flowing modified asphalt is uniform. The situation that the flame retardant in the asphalt at the flowing and dripping parts is insufficient and the effective flame retardance cannot be achieved due to the flowing and dripping of the asphalt is avoided.
Therefore, in the modified asphalt in any area, the organic phosphorus flame retardant can be heated to react, and form a crosslinked solid layer with stable structure, so that the modified asphalt is limited in a certain range, further flowing, dripping and burning of the modified asphalt are prevented, and the flame retardance of the modified asphalt waterproof coiled material can be effectively improved.
