Abstract

The invention belongs to the technical field of pipe repair, and particularly discloses geothermal pipe repairing agent and a preparation method thereof. The repairing agent is prepared from a component A and a component B, wherein the component A is prepared from the following components in parts by weight: 80-100 parts of epoxy resin, 10-20 parts of unsaturated polyester resin, 1-3 parts of cellulose ether, 0.5-1 part of polyving akohol, 1-2 parts of attapulgite, 0.5-1 part of alkylphenol polyoxyethylene and 10-18 parts of filler, and the component B is curing agent. The invention also discloses a preparation method of the geothermal pipe repairing agent. The geothermal pipe repairing agent has excellent construction performance, and a repairing layer has good anti-pressure ability, bonding strength and corrosion resistance. The geothermal pipe repairing agent can be used for repairing the geothermal pipe, can carry out on-line repair, is convenient and quick, and does not affect the normal life of users, and meanwhile, the repair cost can be greatly lowered.

Description

technical field [0001] The invention belongs to the technical field of pipeline repair, and in particular relates to a floor heating pipe repair agent and a preparation method thereof. Background technique [0002] With the development of society and the continuous improvement of people's living standards, traditional heating equipment has been difficult to meet people's needs. Floor heating design has gradually become the trend of people's needs. It is a heating method that bury the floor heating pipes under the floor, add heat-conducting liquid to the floor heating pipes, use hot water or heating cables, and radiate heat evenly to the room through the ground. Compared with traditional heating methods, geothermal radiant heating has the advantages of comfort, energy saving and environmental protection. [0003] At present, the heat transfer liquid used in the floor heating pipe is flowing, that is, it enters from the entrance of the floor heating pipe and then flows out f...
