Problems solved by technology

During the assembly process, because the rock wool is block-shaped, the assembly is cumbersome, and it is not easy to fix with the tank body, and it is easy to generate gaps. The external water vapor can easily adhere to the steel structure surface of the tank body through the gaps and directly contact with the tank body, basically losing the meaning of heat preservation.
Although airgel has a low thermal conductivity, the material is expensive (about 15,000 yuan per cubic meter), and it is difficult to install, and it is not easy to form an integral structure with the tank body

Abstract

The invention discloses an asphalt transportation device and a production method. The asphalt transportation device includes the body of the asphalt transportation device and a layer of polyurethane insulation material covering the outer surface of the body of the asphalt transportation device; the layer of polyurethane insulation material is obtained through curing reaction of material A and material B; material A includes isocyanate; material B is obtained by Parts by weight include 35-50 polyether polyol, 20-30 polyester polyol, 4-8 grafted polyether, 10-20 halogen-free flame retardant, 2-5 silicone oil, 2-5 catalyst and 0.5-5 water . The asphalt transportation device of the invention has good thermal insulation effect, is easy to produce, and the polyurethane thermal insulation material layer is not easy to fall off.

Description

technical field [0001] The invention relates to the technical field of transportation devices, in particular to an asphalt transportation device and a production method thereof. Background technique [0002] In the process of long-distance transportation of asphalt, in order to keep the temperature of the asphalt in the transportation device at an ideal temperature so as to ensure the quality of the asphalt and save energy, the transportation device usually adopts thermal insulation materials during transportation. Generally, it is realized by covering a layer of thermal insulation material on the outside of the rigid structure of the tank body of the transportation device, and the thickness varies with different materials. At present, rock wool and airgel are mainly used to insulate tanks. Rock wool has a high thermal conductivity. After a long time and long-distance transportation, the asphalt in the tank will drop from 180°C to 40°C, basically losing the meaning of heat ...
