Abstract

The invention relates to a viscoelastic anticorrosive material which comprises the following components in parts by weight: 3-8 parts of high-molecular polyisobutene, 20-33 parts of medium-molecular polyisobutene, 10-20 parts of low-molecular polyisobutene, 45-60 parts of inorganic filler, 3-12 parts of terpene resin, 1.5-5 parts of styrene-isoprene-styrene and 0.1-0.5 parts of phthalocyanine green. The weight fraction ratio of the inorganic filler to the high-molecular polyisobutene, the medium-molecular polyisobutene and the low-molecular polyisobutene is increased, the filler and the polyisobutene are fully combined through intermolecular interaction in the mixing process, so that the high and low temperature resistance of the viscoelastic anticorrosive material is improved on the basisthat the viscoelastic anti-corrosion material maintains the good ductility of a polyisobutene-based material. By adding the rest components, the basic performance of the viscoelastic anticorrosive material is guaranteed. Therefore, the comprehensive performance of the anticorrosive material is further improved.

Description

technical field [0001] The invention belongs to the technical field of anti-corrosion materials, and in particular relates to a viscoelastic anti-corrosion material and its preparation method and application. Background technique [0002] Due to irregular shapes, bolts, nuts, valves, flanges and other special-shaped parts of the steel structure, there are many gaps and corners, which are easy to accumulate corrosive media such as water and salt, especially when the ambient temperature is high, corrosion is very easy to occur. At the same time, these special-shaped parts are also stress concentration areas. Corrosion fractures may occur as the corrosion deepens, which will not only affect the safety of use, but even cause safety accidents. These special-shaped parts also have the problem of difficulty in anti-corrosion. Due to the complex structure and difficult surface treatment, after the construction of ordinary anti-corrosion coating or coating structure, the adhesion is ...
