Problems solved by technology

However, the existing traditional anti-corrosion materials mainly have unreasonable raw material allocation, resulting in complicated material allocation, high requirements for production equipment, and complicated production processes, so it is difficult to be popularized and applied. Therefore, we propose a pipeline anti-corrosion polyurea spray elastomer, which is used to solve the above-mentioned problems

Abstract

The invention discloses a pipeline anticorrosion polyurea spraying elastomer. The polyurethane elastomer comprises the following raw material in parts by weight: 10 parts of polyether polyol, 12 partsof a viscosity reducer, 35 parts of a flame retardant, 24 parts of mixed aromatic polyisocyanate, 35 parts of amino-terminated polyether, 45 parts of an amine chain extender, 65 parts of an antioxidant, 35 parts of leveling agent, 45 parts of isocyanate, 15 parts of an amino-terminated alkylene oxide compound, 20 parts of diethyl toluenediamine, 10 parts of diamino, 25 parts of methylthiochlorobenzene, 35 parts of dimethylthiotoluenediamine, 20 parts of dialkyl diamine, 35 parts of dialkyl methyl diamine, 20 parts of phosphite triester, 65 parts of fumed silica, 70 parts of fluorocarbon resinand 65 parts of urea. The pipeline anticorrosion polyurea spraying elastomer has the advantages of simple preparation, less material configuration, low production equipment requirement, simple production process, convenient popularization and application, and strong practicability.

Description

technical field [0001] The invention relates to the technical field of polymer anti-corrosion and waterproof coatings, in particular to a pipeline anti-corrosion polyurea spray-coated elastic body. Background technique [0002] Polymer anti-corrosion and waterproof coatings are built by Fenyangtang Guojia using polymer synthesis technology. They are new super-grade rubber waterproof coatings. Epoxy resin and resin groups are added to make this product more multi-functional and environmentally friendly, giving new products more Waterproof, anti-corrosion, moisture-proof, mildew-proof and other effects [0003] Traditional anti-corrosion materials are generally epoxy, chlorinated rubber, and glass fiber reinforced plastics. Among them, epoxy coatings include high solid powder coatings, water-based coatings, and powder coatings. However, the existing traditional anti-corrosion materials mainly have unreasonable raw material allocation, resulting in complicated material alloca...
