Problems solved by technology

However, its bulk density is larger than other insulation materials, the material toughness is low, the coating performance is poor, and the use process is cumbersome. These shortcomings restrict the development of inorganic materials as insulation materials. Therefore, it is imminent to develop and use an insulation coating suitable for vehicle-mounted asphalt insulation vehicles.

preparation example Construction

[0038] The preparation method of the modified expanded vermiculite is as follows: 10g methylcellulose, 15g sodium dodecylbenzenesulfonate are dissolved in 60mL deionized water, fully stirred with a glass rod to obtain a dispersant solution, and then 100g vermiculite Pour the stone into the ball mill jar, add the previously prepared solution, stir evenly with a glass rod, put it into the planetary mill for ball milling for 2 hours, and the speed of the planetary mill is 200r / min. After the ball milling, pour the product into a glass dish, and It is placed in a vacuum drying oven for drying at a temperature of 70° C. until it is dried, and finally the dried product is pulverized with a pulverizer to obtain modified expanded vermiculite.

[0039]The modified expanded vermiculite is surface-modified expanded vermiculite. Vermiculite is a layered silicate mineral with strong thermal insulation properties. The dispersion of its mineral powder in the organic matrix determines the per...

Abstract

The invention provides a novel nano ceramic thermal insulation material. The novel nano ceramic thermal insulation material comprises a heat insulation layer, an auxiliary layer and an anticorrosion layer. The anticorrosion layer is coated on the surface of a tank body, the auxiliary layer is arranged between the anticorrosion layer and the heat insulation layer. The heat insulation layer is prepared from, by weight, 60-80 parts of nano rare earth hollow ceramic microsphere modified epoxy resin, 30-50 parts of modified vermiculite and 10-15 parts of ceramic fibers. Therefore, the novel nano ceramic thermal insulation material has good thermal insulation performance, a low heat conduction coefficient and a convenient construction; a strip temperature operation of the novel nano ceramic thermal insulation material can be carried out at a certain temperature range, and the novel nano ceramic thermal insulation material is suitable for a vehicle-mounted asphalt insulated car.

Description

technical field [0001] The invention relates to the field of thermal insulation materials, in particular to a nano-ceramic thermal insulation material suitable for asphalt thermal insulation tank vehicles, refrigerated vehicles and thermal insulation pipelines. Background technique [0002] With the rapid development of social economy, higher requirements are put forward for the insulation of the transportation industry. For example, the transportation of liquid asphalt is heated to a liquid state of 150°C to 180°C before the asphalt is transported, filled into the inside of the semi-trailer tank, and directly discharged through the discharge valve after being transported to the destination. Exponential characteristics, if the temperature drops above 20°C, the viscosity will increase greatly, which will bring a lot of inconvenience to unloading. [0003] In the vehicle-mounted asphalt insulation tank, rock wool, glass wool, rubber-plastic sponge, phenolic, foam glass, polyu...
