[0021] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example 1

[0023] like Figure 1~Figure 4 As shown, this embodiment proposes a super-adhesive force SBS elastomer modified asphalt waterproofing membrane, including a waterproofing membrane body 1, a bonding layer 2 is arranged at the top of the waterproofing membrane body 1, a composite layer 3 is arranged at the top of the bonding layer 2, a splicing pad 4 is fixedly connected to one end of the waterproofing membrane body 1, a storage capsule 5 is fixedly connected to the middle of one side of the splicing pad 4, the storage capsule 5 is filled with high-viscosity glue, a protective pad 6 is bonded to the top and bottom of one side of the splicing pad 4, and the end of the protective pad 6 close to the storage capsule 5 is also bonded to the storage capsule 5, and a locking component 8 is arranged at the other end of the waterproofing membrane body 1, and the locking component 8 is used to cooperate with the storage capsule 5 to form a splicing between two waterproofing membrane bodies 1;

[0024] Furthermore, the waterproofing membrane body 1 is compounded by a special process of SBS elastomer and asphalt, wherein the SBS elastomer is copolymerized by three monomers of styrene, butadiene and stearic acid. By setting the above materials, the waterproofing membrane body 1 has excellent elasticity and bonding properties;

[0025] In detail, the material of the bonding layer 2 is a mixture of asphalt and polyacrylate. Polyacrylate is a high molecular organic compound with good water solubility and dispersibility. Adding it to asphalt can improve the water permeability of asphalt, thereby improving the bonding strength;

[0026] The end of the protective pad 6 close to the storage bag 5 is fixedly connected with an adhesive film 7, and the protective pad 6 is adhesively connected to the storage bag 5 through the adhesive film 7. The adhesive film 7 is used to stably connect the protective pad 6 to the storage bag 5, thereby preventing the storage bag 5 from being damaged when not in use.

[0027] The composite layer 3 includes a tensile layer 9, a waterproof layer 10, an anti-aging layer 11 and a wear-resistant layer 12. The top of the adhesive layer 2 is provided with the tensile layer 9, the top of the tensile layer 9 is provided with the waterproof layer 10, the top of the waterproof layer 10 is provided with the anti-aging layer 11, and the outer side of the anti-aging layer 11 is provided with the wear-resistant layer 12;

[0028] In more detail, the material of the tensile layer 9 is polyester fiber, which has many advantages, such as high breaking strength and elastic modulus, moderate resilience, excellent heat setting effect, and good heat resistance and light resistance. Its melting point is about 255°C and its glass transition temperature is about 70°C, so it can effectively improve the tensile strength of the waterproof roll body 1;

[0029] The waterproof layer 10 is made of polyurethane resin, which is a polymer material with excellent mechanical properties formed by polyol and polyisocyanate through polycondensation reaction. It has strong plasticity and the performance of polyurethane elastomer is between plastic and rubber. It is oil-resistant, wear-resistant, low-temperature-resistant, aging-resistant, high in hardness, elastic, and can effectively resist the erosion of various liquids.

[0030] The material of the anti-aging layer 11 is a mixture of diatomite and perlite, wherein diatomite is a natural inorganic mineral material, the main component of which is silicate, which has good adsorption performance and environmental friendliness, and does not contain any harmful substances, and is harmless to the human body and the environment during use. Due to the high porosity of perlite, its thermal conductivity is low, which means that it can effectively prevent the transfer of heat, thereby preventing the waterproof roll body 1 from aging;

[0031] The material of the wear-resistant layer 12 is EPDM, which is a copolymer of ethylene, propylene and a small amount of non-conjugated diene, and is a type of ethylene-propylene rubber, represented by EPDM. Because its main chain is composed of chemically stable saturated hydrocarbons and only contains unsaturated double bonds in the side chain, it has excellent wear resistance such as ozone resistance, heat resistance, and weather resistance, and can effectively reduce the wear of the waterproof membrane body 1;

[0032] Example 2

[0033] like Figure 1~Figure 4 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes a locking assembly 8;

[0034] In this embodiment, the locking assembly 8 includes a positioning pad 13, a bearing pad 14, a positioning groove 15, a locking pad 16, a locking protrusion 17 and a stabilizing strip 18. The other end of the waterproof membrane body 1 is fixedly connected to the positioning pad 13, the bottom end of one side of the positioning pad 13 is fixedly connected to the bearing pad 14, the top of the bearing pad 14 is provided with a plurality of positioning grooves 15, the top of one side of the positioning pad 13 is rotatably connected to the locking pad 16, and the bottom end of the locking pad 16 is fixedly connected to the locking protrusion 17 corresponding to the positioning groove 15;

[0035] In summary, the locking pad 16 is pulled up to lift it up, and the locking protrusion 17 is moved out of the positioning groove 15, and then the storage capsule 5 is placed on the top of the bearing pad 14, and the locking pad 16 is covered down at the same time, so that the locking protrusion 17 squeezes the storage capsule 5, and the storage capsule 5 is crushed, so that the high-viscosity glue flows out, thereby forming a splicing between the two waterproof roll material bodies 1, effectively reducing the steps of splicing between the waterproof roll material bodies 1, making the whole more convenient;

[0036] Furthermore, both sides of the bottom of the locking pad 16 are fixedly connected with stabilizing strips 18, and the bottom end of the stabilizing strip 18 is provided with an adhesive strip, and the adhesive strip is adhesively connected to the bearing pad 14. Through the setting of the stabilizing strip 18, when the bearing pad 14 contacts the locking pad 16, the locking pad 16 can be positioned by the stabilizing strip 18 to avoid separation of the bearing pad 14 and the locking pad 16.

[0037] A specific application of the above two embodiments is that the storage capsule 5 at one of the waterproof roll material bodies 1 is first matched with the bearing pad 14 at the other waterproof roll material body 1, and the protective pad 6 is torn off from the storage capsule 5 and the splicing pad 4 to expose the storage capsule 5, and then the locking pad 16 is pulled up to lift it up, and the locking protrusion 17 is moved out of the positioning groove 15, and then the storage capsule 5 is placed on the top of the bearing pad 14, and the locking pad 16 is covered down at the same time, so that the locking protrusion 17 squeezes the storage capsule 5, breaks the storage capsule 5, and makes the high-viscosity glue flow out, so as to form the splicing between the two waterproof roll material bodies 1, which effectively reduces the steps of splicing between the waterproof roll material bodies 1, making the whole more convenient;

[0038] During the application of the waterproof membrane body 1, the adhesive layer 2 can be used to improve the overall bonding force, and the tensile layer 9, waterproof layer 10, anti-aging layer 11 and wear-resistant layer 12 can be used to improve the overall structural strength, effectively ensuring the application effect of the waterproof membrane body 1.

[0039] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
