In order to solve the technical problems, the invention provides the following technical scheme: a super-cohesive SBS elastomer modified asphalt waterproof coiled material has the following characteristics: the super-adhesive SBS elastomer modified asphalt waterproof coiled material comprises a base, a low-viscosity SBS modified asphalt layer, a super-adhesive SBS modified asphalt layer and a release film, wherein the low-viscosity SBS modified asphalt layer, the super-adhesive SBS modified asphalt layer and the release film are coated on two sides of the base in sequence from inside to outside;
wherein the super-cohesive SBS modified asphalt layer comprises the following components: asphalt, a filler softener, an SBS modifier, an antioxidant, a flame retardant, acrylic acid and carbon black;
the low-viscosity SBS modified asphalt layer comprises the following components: asphalt, filler, softener, SBS modifier and antioxidant.
Further, the super-cohesive SBS modified asphalt layer comprises the following components in parts by weight: 90-120 parts of asphalt, 15-40 parts of filler, 5-10 parts of softener, 10-20 parts of SBS modifier, 3-10 parts of antioxidant, 1-4 parts of polypropylene wax, 4-8 parts of acrylic acid, 3-5 parts of flame retardant and 5-10 parts of carbon black.
The polypropylene wax has the characteristics of high melting point, low melting degree and good lubricity and dispersibility, the melting point is between 130 and 170 ℃ due to different molecular weights, when the super-adhesive SBS modified asphalt layer is prepared, the polypropylene wax can be dispersed in an asphalt matrix after being heated and stirred, the high temperature resistance and mechanical properties of the asphalt matrix are improved, wax components in the asphalt matrix can be gradually separated out after the asphalt matrix is cooled down, and the polypropylene wax gradually drifts to the surface of the super-adhesive SBS modified asphalt layer in the separation process and is uniformly dispersed, so that the surface of the super-adhesive SBS modified asphalt layer is protected by the wax layer, the super-adhesive SBS modified asphalt layer is blocked from being in direct contact with water vapor, the service life of the super-adhesive SBS modified asphalt layer is prolonged, and the wax coating also has the characteristic of wear resistance and can further improve the mechanical properties of the super-adhesive SBS modified asphalt layer.
Further, the low-viscosity SBS modified asphalt layer comprises the following components in parts by weight: 100-120 parts of asphalt, 15-40 parts of filler, 10-25 parts of softener, 5-15 parts of SBS modifier and 3-10 parts of antioxidant.
Further, the tire base is any one of a polyester tire and a glass fiber tire, and the thickness is 1.2-1.5mm.
Furthermore, triangular depressions are formed on the outer side of the low-viscosity SBS modified asphalt layer (2), the depth of the triangular depressions is 0.2-0.4mm, the width of the triangular depressions is 0.1-0.3mm, and the interval of the triangular depressions is 2-5 times of the width of the triangular depressions.
Further, the asphalt is any one of No. 130 asphalt, no. 110 asphalt or No. 90 asphalt; the filler is any one or more of glass fiber, talcum powder, fly ash and calcium carbonate; the softener is any mixture of any one or two of aromatic hydrocarbon oil and cyclic hydrocarbon oil in any proportion.
The naphthenic oil and the aromatic oil are the same as asphalt, are petroleum refined products, can be used as byproducts for producing asphalt and are used in cooperation with the asphalt, have good compatibility with the asphalt, can be used as light components in the asphalt to play a role in reducing the viscosity of the asphalt after being mixed with the asphalt, have good interaction force with PB chain ends in SBS, can increase the movement trend of PB sections, reduce the molecular deformation of SBS, and further improve the fluidity of SBS.
The carbon black is an amorphous black substance generated after incomplete combustion of carbon element, and the main elements of the carbon black comprise carbon element, oxygen element and hydrogen element. As amorphous carbon, carbon black has a huge specific surface area, when the carbon black is added into asphalt as a modifier component, the excessive softener component in the asphalt component can be adsorbed by virtue of the surface area factor of the carbon black, so that the precipitation of the softener component in the use process is avoided, and the waterproof performance is reduced; after the carbon black is filled, the phenomenon of cracking of the waterproof coiled material can be further avoided in the using process, the light components and the softening agent in the waterproof coiled material can be kept for a longer time due to the adsorption effect of the carbon black, the basic performance of the waterproof coiled material can be kept for a longer time, in addition, the carbon black also has excellent ultraviolet absorption capacity, the aging phenomenon of organic components in the waterproof coiled material under the radiation of ultraviolet is reduced, and the service life of the waterproof coiled material is further promoted.
Further, the antioxidant is any one of commercial antioxidants TBY-2246, MD1024 or KY-405; the flame retardant is modified nano zinc oxide, wherein the preparation steps of the modified nano zinc oxide are as follows: adding nano zinc oxide into ethanol solution dissolved with dodecyl trimethyl ammonium chloride, performing ultrasonic oscillation treatment for 10-20min at the frequency of 20-25KHz, and centrifuging to obtain the modified nano zinc oxide.
The nano zinc oxide is used as an inorganic mineral and is often used as a flame retardant to be added into various organic matters, so that the flame retardant effect of the organic matters is improved, and the nano zinc oxide has the characteristics of high thermal stability, low toxicity, no generation of corrosive gas and long flame retardant effect, and is a good flame retardant material.
The shielding capability of nano-sized metal oxide powder on light is maximum when the particle size of the nano-sized metal oxide powder is 1/2 of the wavelength of the light, and the nano-oxidability can show stronger ultraviolet light absorption capability than titanium oxide when the particle size is the same, and can realize shielding effect on long-wave ultraviolet rays and medium-wave ultraviolet rays in an ultraviolet region, so that when nano-zinc oxide is added into an asphalt matrix, the ultraviolet light resistance of the asphalt matrix can be improved, and the performance degradation effect brought by ultraviolet light irradiation can be slowed down.
When the nano zinc oxide is used as a flame retardant to be mixed into the asphalt matrix, the nano zinc oxide can also play an antibacterial role, and pseudosingle cell bacteria and bacilli existing in the nature have better decomposing capability on petroleum hydrocarbon substances, so that alkane and aromatic hydrocarbons contained in the asphalt matrix can be decomposed. When the nano zinc oxide contacts with the bacteria, zinc ions are combined with cell membranes on the surfaces of the bacteria and react with hydroxyl groups and carboxyl groups contained on the nano zinc oxide to destroy cell membrane structures, so that the aim of resisting bacteria is fulfilled.
Further, the SBS modifier is a mixture of star SBS and linear SBS, and the ratio of the star SBS to the linear SBS is (1.5-2.5) in parts by weight: (2-3.5).
The linear SBS and the star SBS can both play a role in modifying the asphalt component, so that the high-temperature performance and the low-temperature performance of the asphalt component are improved, a net structure is formed in the asphalt component, the cohesive force of the asphalt component is improved, and the viscosity of the asphalt component is improved; compared with linear SBS, the star SBS has larger relative molecular weight, high cohesive strength, better physical crosslinking, heat resistance and elastic modulus, and better asphalt modification effect than linear SBS, but when the using amount of the star SBS is too large, the internal shrinkage stress of the whole asphalt is too strong due to the too high cohesive force, so that the dispersion and the paving of an asphalt matrix are not facilitated, and the star SBS and the linear SBS are commonly used in use.
Further, the thickness of the low-viscosity SBS modified asphalt layer is 0.8-1.2mm, and the thickness of the super-cohesive SBS modified asphalt layer is 1.2-1.5mm.
