[0028] In a preferred embodiment, the adhesive layer 2 is made of chloroprene rubber as the main raw material, and vulcanizing agent, accelerator, antioxidant and solvent are added. The adhesive layer 2 is bonded with the base layer 1 by cold bonding. The fire -retardant layer 31 and the asphalt layer 32 are bonded by cold bonding, which is simple and convenient, and effectively replaces the hot melt connection method to avoid damaging the layers such as the fire -retardant layer 31.

[0029] In a preferred embodiment, the waterproof layer 4 is installed above the adhesive layer 2, and the first rubber separation layer 5 is bonded to the inner side of the waterproof layer 4.

[0030] The reinforcing assembly 6 is installed outside the first rubber separation layer 5, and the reinforcing assembly 6 includes the glass mesh 61 and the polyester fiber fabric 62.

[0031] The glass mesh 61 is bonded to the outer surface of the first rubber separation layer 5, and the second rubber separation layer 7 is bonded to the outer surface of the glass mesh 61.

[0032] The glass mesh 61 is made of glass fiber, which is an inorganic non-metallic material and is composed of silicon dioxide.

[0033] The polyester fiber fabric 62 is bonded to the outer surface of the second rubber separation layer 7 to improve the stability.

[0034] Specifically, the working process or working principle of the flame-retardant waterproof roll material is as follows: due to different positions of the waterproof roll material, different main effects are achieved. When the waterproof roll material is used indoors, for example, in a shopping mall, the interior of the shopping mall is crowded with people and goods, the electrical equipment and lighting system are complex, and the fire hazard is large. Therefore, it is necessary to use the fireproof waterproof roll material on the roof of the shopping mall, underground parking lot and ventilation duct, and the like. Therefore, the product is designed to solve the problem.

[0035] The flame-retardant layer 31, the heat insulation layer 311, the asphalt layer 32 and the high polymer material layer 33 are installed outside the base layer 1 to improve the flame-retardant effect of the product, so that the product can burn when a fire occurs, and greater danger can be avoided. Specifically, the base layer 1 is arranged at the bottommost position, the reinforcing assembly 6 is arranged above the base layer 1, the first rubber layer 5 is installed above the reinforcing assembly 6, the waterproof layer 4 is installed on the upper surface of the first rubber layer 5, and the flame-retardant assembly 3 is arranged above the waterproof layer 4. The flame-retardant layer 31 is arranged at the uppermost position to improve the flame-retardant effect of the waterproof roll material, and the flame-retardant layer 31 arranged at the uppermost position can protect the waterproof layer 4, so that the waterproof layer 4 is not damaged due to high temperature and the waterproof effect of the waterproof roll material is affected.

[0036] The flame-retardant layer 31 in the product is usually based on a high molecular polymer, such as rubber, plastic and the like. Rubber, such as ethylene-propylene-diene rubber, has a stable molecular structure and excellent aging resistance. A flame retardant, commonly a halogen-based flame retardant, is added to these base materials. The halogen-based flame retardant releases hydrogen halide gas when burning. This gas can capture free radicals in the combustion process, thereby interrupting the combustion reaction chain. For example, hydrogen chloride produced by chlorinated paraffin when heated can react with hydroxyl radicals OH produced by combustion, thereby preventing the continuation of the combustion reaction and achieving the effect of flame retardation.

[0037] The asphalt layer 32 is an SBS styrene-butadiene-styrene block copolymer modified asphalt material, which has good flexibility and weather resistance and also has the effect of flame retardation. The main component of the high polymer material layer 33 is ethylene, propylene and a small amount of non-conjugated diene hydrocarbon. Ethylene and propylene form a main chain structure through a copolymerization reaction, providing good elasticity and weather resistance. The addition of non-conjugated diene hydrocarbon, such as dicyclopentadiene, can introduce unsaturated double bonds into the rubber molecular chain, facilitating vulcanization reaction, thereby improving the crosslinking density and physical properties of the rubber. In the waterproof roll material, the rubber can be used for a long time in the temperature range of -40℃ to 120℃.

[0038] The main component of the thermal insulation layer 311 is a thermal insulation material, such as rock wool, which is mainly composed of natural rocks such as basalt and gabbro, etc. After high-temperature melting, it is made into a fibrous material by centrifugal force or blowing. The fibers of rock wool are long and slender, with many small pores inside. Its thermal conductivity is about 0.03-0.045 W / (m·K), with good thermal insulation performance and fireproof performance, which can improve the flame retardant effect of the product, and can avoid affecting the waterproof layer 4 under the action of the thermal insulation layer 311.

[0039] When laying the product, the shape of the product laying can be adjusted according to the laying site. When the shape of the product needs to be laid in an arc shape, the product needs to be laid in a curved shape. In order to avoid damage to the product during bending and affect use, the product also adds a reinforcing component 6.

[0040] The glass mesh cloth 61 in the reinforcing component 6 has the advantages of high strength, high modulus, high temperature resistance, and chemical corrosion resistance, which can significantly improve the tensile strength and tear resistance of the roll material, making it less likely to be damaged during use. The mesh structure of the glass fiber mesh cloth can effectively disperse stress. When the roll material is subjected to external force, the stress can be uniformly transmitted through the mesh cloth, thereby reducing local stress concentration and preventing the roll material from cracking or breaking, thereby prolonging the service life of the roll material.

[0041] The main component of the polyester fiber fabric 62 is polyester, which is a high molecular compound made by condensation reaction of organic diacid and diol. Polyester fiber has high strength and elastic recovery ability, and also has good wear resistance and weather resistance. The reinforcing layer in the form of fabric can increase the overall strength and flexibility of the roll material, so that it can better adapt to the deformation and vibration of the base layer. The fibers of the polyester fiber fabric 62 are interwoven with each other to form a stable structure, which can provide effective support and constraint when the roll material is subjected to deformation such as stretching and bending, maintain the shape and integrity of the roll material, and improve the durability of its waterproof performance.

[0042] The use of glass mesh cloth 61 and polyester fiber fabric 62 can improve the stability of the product during use.
