Embodiment 1

[0043] 50kg of environmentally friendly water-based epoxy resin emulsion, 5kg of titanium dioxide, 20kg of graphene powder, 3kg of water-based paint additives, 3kg of surfactants, 5kg of defoamers, 5kg of polyurethane thickeners, 3kg of kaolin, 3kg of pure acrylic emulsion, anti-corrosion 3kg of the agent was stirred and mixed, and the thermally conductive coating was obtained after mixing evenly.

Embodiment 2

[0045](1) Select high-quality low-carbon steel pipes for pickling and phosphating (oil removal---rust removal---water washing---neutralization---water washing---surface adjustment---phosphating---water washing-- -passivation---drying) treatment to lay a good surface foundation for strengthening the coating adhesion in the next step. Put the phosphating steel pipe on the automatic assembly line of the special tooling table to coat the heat-conducting paint, and avoid the close contact between the pipe and the pipe to prevent the adhesion between the coatings. The thermally conductive coating has good thermal conductivity and strong adhesion. The thickness of the coating should be uniform and controlled at about 40um. Put the coated steel pipe into a baking oven for drying at a temperature of 130°C for 9 minutes.

[0046] (2) The aluminum profile should also undergo strict pickling-water washing-alkali corrosion-water washing-chromizing treatment; the coated steel pipe is insert...

Abstract

The invention discloses a bimetal composite radiator capable of reducing friction abnormal sound and a preparation method thereof. The preparation method comprises the following steps of: coating the outer part of a low-carbon steel pipe with a layer of coating, and then drying the coating; penetrating the steel pipe with the coating into an aluminum profile for the bimetal composite radiator, and carrying out shrinkage pipe interference magnitude compounding on an aluminum pipe in the aluminum profile for the bimetal composite radiator and the low-carbon steel pipe inserted into the aluminum pipe, so that the low-carbon steel pipe and the aluminum pipe are tightly combined to obtain a bimetal composite pipe; and welding the bimetal composite pipe into a radiator, and carrying out secondary drying on the radiator to obtain the bimetal composite pipe, and welding the bimetal composite pipe into the radiator. The aluminum profile for the bimetal composite radiator comprises the aluminum pipe; and the opening ends of the aluminum pipe are respectively provided with a telescopic angle, and the diameter of the bulge of each telescopic angle is 2.8 + / - 0.1mm. The bimetal composite radiator prepared by the method can effectively solve the friction abnormal sound generated by thermal expansion and cold contraction between the low-carbon steel pipe and the aluminum pipe, and a quiet and comfortable use environment is provided for a user.

Description

technical field [0001] The invention relates to the technical field of bimetallic composite radiators, in particular to a bimetallic composite radiator for reducing frictional noise and a preparation method thereof. Background technique [0002] The radiator is an important and basic component in the hot water (or steam) heating system. The hot water cools down in the radiator (or the steam condenses in the radiator) to supply heat to the room to achieve the purpose of heating. Since the heat transfer medium in the radiator is generally water with a temperature lower than 95°C, and aluminum has a fast heat dissipation and good heat conduction effect, the radiator generally uses aluminum as a raw material. However, because aluminum is not resistant to corrosion and pressure, it cannot be used as a heat sink only with aluminum. Generally, low-carbon steel pipes are added to the aluminum pipes. Low-carbon steel pipes are corrosion-resistant and pressure-resistant but have poo...
