Double-layer anti-aging waterproof adhesive tape

Abstract

The invention relates to a double-layer anti-aging waterproof adhesive tape. The adhesive tape comprises a core layer and an adhesive material, wherein the adhesive material is applied to the upper and lower surfaces of the core layer, the core layer comprises a waterproof layer and an anti-aging layer, the adhesive material is in a film-like shape and comprises the following raw materials in parts by weight: 70-90 parts of high-density polyethylene, 10-30 parts of low-density polyethylene, 1-3 parts of an antioxidant and 3-5 parts of graphite master batch, the anti-aging layer comprises an upper anti-aging layer and a lower anti-aging layer, wherein the upper and lower anti-aging layers are respectively applied to an upper surface and a lower surface of the waterproof layer. The waterproof adhesive tape disclosed by the invention has the advantages of high tensile strength, good water-proof performance and permeability resistance and simple and flexible operation in the construction, by virtue of addition of an acid-resistant layer and a reinforced rib layer, the adhesive tape has acid-resistant and deformation-resistant effects, can be widely used for modular connections of waterproof rolled materials of various building parts, such as roofs, floors, walls, basements, water pools, swimming pools in constructional engineering and can be also used for local emergency waterproof joint filling of subways, tunnels, dams, landfills and other structures.

Description

technical field

[0001] The invention relates to a double-layer anti-aging waterproof adhesive tape. Background technique

[0002] Adhesive tapes can be classified according to their functions: high-temperature tapes, double-sided tapes, insulating tapes, special tapes, pressure-sensitive tapes, die-cut tapes, etc. Tapes with different functions are suitable for different industry needs. A layer of adhesive is coated on the surface of the tape to make the tape stick to objects. The earliest adhesives come from animals and plants. In the 19th century, rubber was the main component of adhesives, but in modern times, various polymers are widely used. Adhesives can stick to things because of the formation of bonds between their own molecules and the molecules of the objects to be connected, and this bond can firmly bind the molecules together. Adhesive tape can be used in almost all kinds of industries and occasions, but when used in some humid environments, due to the intrusio...
