Abstract

The invention discloses a viscoelastic body anti-mildew and anticorrosion adhesive for buried pipelines, an adhesive tape and a preparation method thereof, and belongs to the technical field of pipeline anticorrosion. The viscoelastic body anti-mildew and anticorrosion adhesive is composed of the following components, by weight, 100-300 parts of a polymer viscous-elastic material, 1-10 parts of enhancing glue, 100-300 parts of a filling material, 1-10 parts of an antioxidant, 1-10 parts of a plasticizer, 1-5 parts of a mildew preventive and 0.1-0.5 part of a pigment. By adding the mildew preventive in the viscoelastic body anti-mildew and anticorrosion adhesive, erosion of mildew can effectively be prevented, and shear strength and volume resistivity of the adhesive layer can be enhanced by cooperation with other components in the formula. Thus, the adhesive's peel strength of a steel or PE material is raised, and mechanical property of the adhesive layer is improved. By the use of the adhesive, buried pipelines made of different materials can be glued well. The adhesive has a good effect of inhibiting common mildews such as aspergillus flavus, aspergillus niger, aspergillus sydowi, aspergillus terreus, aspergillus ustus, Penicilnum chysogenum, Cladosporium, cheatomium, trichoderma and the like.

Description

technical field [0001] The invention relates to a viscoelastic anti-mildew and anti-corrosion adhesive for buried pipelines, a method for preparing the anti-mildew and anti-corrosion adhesive, and also relates to a viscoelastic anti-mold and anti-corrosion adhesive tape for buried pipelines and its preparation The method belongs to the technical field of pipeline anticorrosion. Background technique [0002] Corrosion prevention of pipes refers to the measures to slow down or prevent the corrosion and deterioration of pipelines under the chemical and electrochemical action of internal and external media or the metabolic activities of microorganisms. In pipeline systems, the definition of corrosion is: based on the specific pipeline environment, chemical reactions, electrochemical reactions and microbial erosion in all metallic and non-metallic materials in the pipeline system, which can lead to corrosion of pipeline structures and other materials. damage and loss. In additi...
