Novel thermal-insulated pipeline material and preparation method thereof

Abstract

The invention provides a novel thermal-insulated pipeline material and a preparation method thereof. The material is prepared in the following steps: (1), nano silica, a silane coupling agent KH-560, phenyltriethoxysilane, isopropanol and water are mixed, stirred by a magnetic stirrer for 40-60 minutes and then subjected to ultrasonic dispersion for 20--30 minutes; (2), the mixture is put into a drying oven to be dried after being filtered; (3), the dried nano silica is mixed with polybutene, bisphenol-A-epoxy resin, magnolol, polyethylene wax, dibutyltin maleate, dioctylin oxide, lauryl sodium sulfate, sodium dioctyl sulfosuccinate,propylene glycol alginate, tristearin, kojic acid dipalmitate and polypropylene fibers, and then the mixture is dispersed in a high-speed dispersion machine; (4), the mixture is added to a double-screw extruder to be extruded and formed. The novel thermal-insulated pipeline material has extremely low thermal conductivity and good thermal-insulation performance and can be used at the higher temperature, and the material reaches a non-combustion A level.

Description

technical field [0001] The invention relates to the field of materials, in particular to a novel thermal insulation pipeline material and a preparation method thereof. Background technique [0002] Insulation technology refers to a technological measure taken to reduce the heat transfer from the internal heat source of the heat preservation object to the outside, which can be seen everywhere in our production and life. In life, people are most familiar with refrigerators and thermos cups, but in production, the insulation of pipelines is particularly important. In recent years, due to the shortage of resources, various price adjustments have been made, and electricity prices are one of them, which has greatly increased the industrial cost of heat production from electricity. In addition, the economic losses caused by the heat dissipation of thermal pipes have also increased significantly. Therefore, the insulation effect of the pipeline has a direct and significant impact o...

Problems solved by technology

In recent years, due to the shortage of resources, various price adjustments have been made, and electricity prices are one of them, which has greatly increased the industrial cost of heat production from electricity. In addition, the economic losses caused by the heat dissipation of thermal pipes have also increased significantly. Therefore, the insulation effect of the pipeline has a direct and significant impact on the loss of energy consumption and economic benefits of the enterprise.
