Problems solved by technology

The existing pipeline anti-corrosion method mainly adopts three-layer independent structure, namely: petrolatum primer + petrolatum tape + PE butyl protective tape; the construction process of this anti-corrosion method is complicated and cumbersome, and the construction cost is high; specifically, its construction The process is: manual mechanical rust removal → manual primer application → petrolatum tape winding → PE butyl protective tape winding and fixing; each of the above steps has shortcomings, among which, the rust removal level achieved by manual mechanical rust removal process is not high, The rust removal effect is average; in the manual primer application step, the primer coating uniformity is poor; in the petrolatum tape winding step, the petrolatum tape has almost no bonding strength, and it is easy to slip when winding; in the protective tape winding step, PE butyl The adhesive force between the protective tape and the petrolatum tape is very weak, and gaps are likely to occur at the bonding and lap joints of the tape, which cannot well achieve the purpose of protecting the petrolatum tape and blocking water

Abstract

The invention discloses a hot-melt anticorrosion glue, the raw materials for which are prepared include the following components in terms of mass percentage: 25-40% of petrolatum, 20-30% of styrene-isoprene-styrene synthetic rubber, 15% of petroleum resin ~25%, mineral oil 5~10%, aluminum hydroxide 10~15%, rust inhibitor 3~5%, antifungal agent 1~3%, antioxidant 1~2%. The invention also discloses a hot-melt anti-corrosion adhesive tape and a preparation method thereof. The hot-melt anti-corrosion adhesive tape includes a composite anti-corrosion adhesive layer and a release film on the composite anti-corrosion adhesive layer. The composite anti-corrosion adhesive layer is made of a base material , non-woven fabric and hot-melt anti-corrosion adhesive composite. The hot-melt anti-corrosion tape has good adhesion and high bonding strength, and can be directly wound on the pipeline when in use. It is convenient for construction and does not require multi-step anti-corrosion process. Rust, mildew, anti-corrosion effect.

Description

technical field [0001] The invention belongs to the technical field of adhesive tapes, and in particular relates to a hot-melt anti-corrosion adhesive, a hot-melt anti-corrosion adhesive tape and a preparation method thereof. Background technique [0002] The joints of buried steel pipelines such as petroleum, natural gas transmission, chemical industry, water supply and drainage in urban construction, and gas transmission need anti-corrosion treatment. The existing pipeline anti-corrosion method mainly adopts three-layer independent structure, namely: petrolatum primer + petrolatum tape + PE butyl protective tape; the construction process of this anti-corrosion method is complicated and cumbersome, and the construction cost is high; specifically, its construction The process is: manual mechanical rust removal → manual primer application → petrolatum tape winding → PE butyl protective tape winding and fixing; each of the above steps has shortcomings, among which, the rust re...
