Problems solved by technology

The traditional petrolatum anti-corrosion paste has poor temperature resistance, which is specifically reflected in the two indicators of dropping point and temperature resistance fluidity. When it is used under certain high temperature application conditions, the material performance is unstable, which may easily lead to leakage. Occurrence of oil problems

Abstract

The invention provides epoxy modified high-temperature petrolatum anti-corrosion paste. The epoxy modified high-temperature petrolatum anti-corrosion paste is composed of a component A and a componentB, wherein the component A is mainly prepared from the following raw materials in parts by weight: 100 parts of petrolatum, 10-50 parts of paraffin, 50-200 parts of mineral oil, 10-50 parts of a tackifier, 5-20 parts of an anti-corrosion agent, 10-100 parts of epoxy resin and 100-500 parts of pigments and fillers; and the component B is mainly prepared from the following raw materials in parts byweight: 100 parts of a composite curing agent and 50-120 parts of pigments and fillers. The epoxy modified high-temperature petrolatum anti-corrosion paste has excellent high-temperature resistance,and particularly shows that the dropping point index and the temperature-resistant flowing property are far higher than the requirements of the national standard GB / T 32119, so that the oil seepage phenomenon occurring in long-term high-temperature use is greatly reduced, and the stability of the performance of the anti-corrosion paste is kept; and the paste has good application operation performance, specifically has a relatively high consistency index and meets the standard requirements.

Description

technical field [0001] The application relates to the technical field of petrolatum-coated anti-corrosion technology, in particular to an epoxy-modified high-temperature petrolatum anti-corrosion paste and a preparation method thereof. Background technique [0002] At present, the anti-corrosion technology coated with petrolatum has been relatively mature, and its basic structure consists of three layers, namely, petrolatum anti-corrosion paste (also called primer), anti-corrosion belt, outer protective cover (also called armor), Among them, the outer protective cover has various forms, such as high-density polyethylene armor, polyethylene foam composite FRP or reinforced FRP corrosion protection cover, etc. Among them, petrolatum anti-corrosion paste is one of the core materials of coating technology, located in the innermost layer, directly in close contact with the metal substrate to be protected, forming a protective sealing layer. [0003] During the use of petrolatum ...
