Description

Technical Field

[0001] This application relates to the field of asphalt shingle technology, and in particular to a waterproof and mildew-proof double-layer fiberglass asphalt shingle. Background Technology

[0002] Fiberglass-reinforced asphalt shingles are one of the main materials commonly used for roof waterproofing. Due to their diverse shapes, wide range of applications, heat insulation, heat preservation, simple construction, and low overall cost, they are increasingly favored by the market.

[0003] Common fiberglass asphalt shingles, such as the fiberglass-reinforced asphalt waterproof shingles disclosed in announcement number CN210105132U, consist of a ceramic-coated granule layer, a first asphalt layer, a fiberglass layer, a second asphalt layer, and a fine sand particle isolation layer from top to bottom, which provides a certain degree of waterproofing. However, this asphalt shingle, especially its surface ceramic-coated granule layer, has poor antibacterial and anti-mildew effects, and its surface is rough, making it prone to the growth of bacteria, mold, and other microorganisms with long-term use. This not only affects the appearance of the shingle but also its service life.

[0004] Based on this, this application aims to disclose an asphalt shingle that is waterproof and mildew-proof.

[0005] The above content is only used to help understand the technical solution of this application and does not represent an admission that the above content is the closest prior art to this application. Summary of the Invention

[0006] Based on this, this application provides a waterproof and mildew-resistant double-layer fiberglass asphalt shingle to solve one of the above-mentioned technical problems.

[0007] The technical solution adopted by this application to solve its technical problem is: a waterproof and mildew-proof double-layer fiberglass asphalt shingle, comprising: a main board and a base plate, wherein an installation groove is formed at the bottom of the main board and a protrusion matching the installation groove is formed at the top of the base plate, the main board and the base plate are connected together by the cooperation of the installation groove and the protrusion, and the main board and the base plate are respectively composed of a nano copper coating, a zinc oxide particle layer, a modified asphalt layer, a fiberglass layer, a modified asphalt layer, and a sandy mineral particle layer from top to bottom, forming a six-layer structure.

[0008] In some embodiments, the upper surface of the protrusion is further provided with a self-adhesive area having self-adhesive properties.

[0009] In some embodiments, a guide ramp is formed on one side of both the motherboard and the base plate.

[0010] In some embodiments, an antioxidant is added to the modified bitumen layer.

[0011] In some embodiments, the glass fiber layer is composed of multiple layers of glass fiber mesh.

[0012] In some embodiments, the base plate and the main plate can withstand a lateral tensile force of 400N or more and a longitudinal tensile force of 600N or more.

[0013] The beneficial effects of this application are as follows:

[0014] 1) The surface of the asphalt shingles uses a nano-copper coating, which can enhance the antibacterial effect, maintain good durability and weather resistance, and is cost-effective.

[0015] 2) The zinc oxide granular layer has a certain anti-mildew effect. When used in conjunction with the nano copper coating, the anti-mildew effect is further improved. It can also reflect ultraviolet rays and protect the underlying modified asphalt layer from ultraviolet degradation. The zinc oxide granular layer can also increase the surface wear resistance and aesthetics.

[0016] 3) Antioxidants are added to the two modified asphalt layers, which can slow down the aging process of the asphalt and extend its service life; while the glass fiber layer between the two modified asphalt layers, with glass fiber mesh as the base material, provides strength and stability to the tile and prevents tearing and deformation.

[0017] 4) The bottom layer of sandy mineral particles can increase the friction of asphalt shingles, prevent them from sliding, and also protect the modified asphalt layer.

[0018] Double-layered fiberglass asphalt shingles further enhance their waterproof and moisture-proof capabilities, and the addition of a base plate allows for extending the length of the asphalt shingles as needed. Attached Figure Description

[0026] In the embodiments of this application, please refer to Figure 1-4 As shown, this waterproof and mildew-proof double-layer fiberglass asphalt shingle mainly includes: a main board 1 and a base plate 2. The bottom of the main board 1 has an installation groove 3, and the top of the base plate 2 has a protrusion 4 that matches the installation groove 3. The main board 1 and the base plate 2 are connected together through the cooperation of the installation groove 3 and the protrusion 4. The main board 1 and the base plate 2 are respectively composed of a nano copper coating 5, a zinc oxide particle layer 6, a modified asphalt layer 7, a fiberglass layer 8, a modified asphalt layer 9, and a sandy mineral particle layer 9 from top to bottom, forming a six-layer structure.
