Description

Technical Field

[0001] This utility model relates to the field of waterproof membrane technology, and in particular to an antibacterial waterproof membrane. Background Technology

[0002] Antibacterial and waterproof membrane is a building material that combines antibacterial and waterproof functions. It is widely used in building fields that require both waterproof and antibacterial functions, such as basements, bathrooms, kitchens, swimming pools and other damp environments. In addition, some special fields such as hospitals and food processing plants also need to use antibacterial and waterproof membrane to ensure environmental hygiene.

[0003] However, existing antibacterial and waterproof membranes, under high temperatures or other factors, do not adhere tightly to the building surface. This can easily lead to expansion and bulges in some areas of the membrane. When the bulges are large, they can directly stretch the membrane, causing the antibacterial interlayer inside to break due to the stretching, thus destroying the antibacterial effect of the membrane.

[0004] To solve this technical problem, this utility model proposes an antibacterial and waterproof membrane. Utility Model Content

[0005] The main objective of this invention is to provide an antibacterial and waterproof membrane that can effectively solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] An antibacterial and waterproof membrane includes a waterproof base layer, an antibacterial interlayer on the lower surface of the waterproof base layer, the antibacterial interlayer including a mesh-like antibacterial material, deformable material disposed within the gaps of the mesh-like antibacterial material, and circular holes formed within the deformable material, an adhesive layer on the lower surface of the antibacterial interlayer, a protective film layer on the upper surface of the waterproof base layer, and a plastic film on the lower surface of the adhesive layer, with all layers connected together by an adhesive.

[0008] Preferably, the waterproof base layer is made of asphalt and polymer materials.

[0009] Preferably, the mesh-like antibacterial material is mesh-like and is made of inorganic antibacterial material.

[0010] Preferably, the deformable material is made of a material with high elasticity and needs to have good plasticity.

[0011] Preferably, the adhesive layer is made of cold primer and a special adhesive for waterproof polymer membranes.

[0012] Preferably, the protective film layer is made of reflective heat-insulating coating or polyurethane heat-insulating coating.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] In this invention, by incorporating a mesh-like antibacterial material and a deformable material, when the roll material bulges, the deformable material is stretched to release the air inside the bulge, thereby relieving pressure and preventing the antibacterial interlayer from breaking due to stretching. After pressure relief, the roll material returns to its original shape. Once it returns to its original shape, the deformable material shrinks, thereby minimizing the diameter of the round holes to prevent the invasion of rainwater or bacteria.

[0015] In this invention, a protective film layer made of heat-insulating material is provided to protect the waterproof membrane from damage caused by ultraviolet rays, high temperatures and other harsh environmental factors, thereby extending its service life. The plastic film is provided to protect the adhesive layer before the membrane is used, preventing it from being contaminated by external dust, thus ensuring its adhesion.

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] like Figure 1-2 As shown, an antibacterial waterproof membrane includes a waterproof base layer 1, which is made of asphalt and polymer materials. The asphalt, after being mixed with polymer and filler, has good water resistance, weather resistance and durability. The polymer waterproof membrane is made of polymer materials as the main raw material and has excellent water resistance, weather resistance, corrosion resistance and aging resistance.

[0021] An antibacterial interlayer 2 is provided on the lower surface of the waterproof base layer 1. The antibacterial interlayer 2 includes a mesh-like antibacterial material 3. The mesh-like antibacterial material 3 is mesh-like, and this shape has good tensile strength, which can prevent it from being broken. It is made of inorganic antibacterial materials, including metal nanoparticles, metal oxide nanoparticles, as well as two-dimensional materials such as graphene, black phosphorus, and molybdenum disulfide. These materials have broad-spectrum antibacterial properties and can effectively inhibit the growth of bacteria, mold and other microorganisms.

[0022] Deformable material 4 is provided in the gaps of the mesh-like antibacterial material 3. The deformable material 4 has round holes 5. The deformable material 4 is made of a material with strong elasticity and needs to have good plasticity so that when the roll material bulges, it can release the air inside the bulge through its own properties.

[0023] An adhesive layer 6 is provided on the lower surface of the antibacterial interlayer 2. The adhesive layer 6 is made of cold primer oil and special adhesive for polymer waterproof membrane. The cold primer oil is a solvent-based waterproof coating made of asphalt and diluent. It has the characteristics of strong penetration, fast drying and strong adhesion. It can penetrate into the tiny pores of the substrate surface to form a dense waterproof layer, thereby improving the adhesion between the waterproof membrane and the object. The special adhesive for polymer waterproof membrane is designed for polymer waterproof membrane and can provide strong adhesion and durability.

[0024] A protective film layer 7 is provided on the upper surface of the waterproof base layer 1. The protective film layer 7 is made of reflective heat insulation coating and polyurethane heat insulation coating. The reflective heat insulation coating is a highly reflective coating that can effectively reflect infrared and ultraviolet rays in sunlight, reduce the accumulation of heat on the surface of the waterproof membrane, and thus lower the temperature of the membrane. The polyurethane heat insulation coating not only has excellent waterproof performance, but also has high weather resistance and ultraviolet resistance.

[0025] A plastic film 8 is provided on the lower surface of the adhesive layer 6. The plastic film 8 can protect the adhesive layer 6 from being contaminated by external dust, thereby ensuring its adhesion. All layers are connected together by adhesive.

[0026] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
