Abstract

The invention discloses floor heating heat conduction liquid and a preparation method thereof, and relates to the technical field of heat conduction liquid. The floor heating heat conduction liquid comprises the following components in percentage by mass: 10-15% of purified water, 1.0-1.5% of a corrosion inhibitor, 2-5% of a scale inhibitor, 0.2-0.5% of a bactericide, a defoaming agent 10PPM, 0.2-0.4% of an alkalinity regulator and the balance of an anti-freezing agent, wherein the anti-freezing agent is propylene glycol. The floor heating heat conduction liquid is safe and environmentally friendly, does not generate corrosive influence on floor heating equipment, and can remarkably improve the heat conduction effect of floor heating.

Description

technical field [0001] The invention belongs to the technical field of heat-conducting fluid, and particularly relates to a floor-heating heat-conducting fluid and a preparation method thereof. Background technique [0002] Heating is an indispensable heating equipment for northern families, and thermal fluid is indispensable for the equipment circulation system. Conventional thermal fluids use tap water or automotive antifreeze. Adding water to the heating pipe can improve the heat conduction effect of the floor heating, but after the heating of the floor heating stops, the heating pipe is easy to freeze, and the pipe is frozen and cracked. At the same time, after the heating is stopped, the water will cause corrosion and rust to the equipment, shortening the service life of the equipment. [0003] Vehicle antifreeze is mainly ethylene glycol type or methanol type, and methanol is easy to volatilize, which can cause harm to the human body and even blindness in severe case...
