Description
Technical Field
The invention relates to an environment-friendly odorless modified asphalt waterproof coiled material and a preparation method thereof.
Background
Since the seventies, developed countries in the world have changed in the aspect of waterproof material structures, and have gradually developed to novel waterproof materials such as modified asphalt, self-adhesive materials, synthetic polymer materials, and the like. At present, foreign novel waterproof materials account for more than 90% of the total amount of the market, and the quality, the function and the service life of products reach a higher level. Since the asphalt coiled material is applied in the last 70 th century in China, asphalt waterproof materials are always the leading products of building waterproofing, which account for about 70% of the total market amount recently, only about 10% of high polymer waterproof materials, and other waterproof coatings and other waterproof materials. The polyethylene polypropylene fiber composite waterproof coiled material is a popular waterproof material, but the polyethylene polypropylene fiber composite waterproof coiled material in the market still has a plurality of problems, such as poor waterproof performance, low tensile property, non-ideal environmental protection effect, fussy construction and the like.
The elastomer modified asphalt waterproof coiled material (SBS) produced in China at present is basically mature in technology, but still has many problems, and due to a series of reasons that in the material preparation process, the dosage is not accurate enough, the temperature control is unstable in the oxidation process, the proportioning method is too old and the like, the product quality is unstable, and the defects of poor ageing resistance and oxidation resistance, low elongation and short service life exist. A large amount of asphalt smoke is generated in the process of heating asphalt to prepare asphalt products and the process of heating asphalt to prepare waterproof rolls, which has serious influence on the surrounding environment and is harmful to the health of people.
The smoke contains various organic matters including carbocyclic hydrocarbon, cyclic hydrocarbon derivatives and other compounds, which have harmful effects on human health, and the asphalt smoke contains various polycyclic aromatic hydrocarbon substances including benzopyrene, benzanthracene, carbazole and the like, most of which are carcinogenic and strong carcinogenic substances, the particle size is 0.1-1.0 mu m mostly, the minimum is only 0.01 mu m, the maximum is about 10.0 mu m, and especially the smoke contains various carcinogenic substances represented by 3, 4-benzopyrene. The main way of harming human health is to attach the fly ash below 8um and suck the fly ash into human body through respiratory tract. Therefore, the purification treatment of the asphalt smoke is very necessary to ensure that the emission meets the atmospheric environmental standard.
CN108382039A provides a net flavor modified asphalt waterproof coiled material, which comprises modified asphalt, polypropylene fabric and a PE film, wherein the modified asphalt comprises the following components in parts by weight: 35-45 parts of asphalt, 15-25 parts of waste rubber powder, 15-30 parts of SBS rubber, 0.5-2 parts of stabilizer, 0.5-1 part of antioxidant, 0.5-1 part of odor inhibitor and 10-20 parts of filler. Because the temperature of the modified asphalt is higher in the preparation process of the waterproof coiled material, the asphalt is easy to age, and the waterproof durability of the coiled material is different.
