Expansion vitrification micro-bead thermal insulation pipe case and production method thereof

Abstract

The invention discloses an environment-friendly nonflammable insulating pipe casing with good insulating effect and light volume weight. The insulating pipe casing is produced in such a way that mixed materials are molded into insulating pipe casings with different calibers and different thickness, and the insulating pipe casings are dried and then directly used for the insulation of pipelines. The environment-friendly nonflammable insulating pipe casing is constructed simply and conveniently and has good insulation effect. The insulating pipe casing includes the following components by weight percent: 10 to 15 percent of expansion vitrified beads, 12 to 15 percent of brucite, 10 to 12 percent of attapulgite, 10 to 13 percent of casi powders, 0.1 to 0.15 percent of binders, 0.2 to 0.3 percent of latex, 45 to 54 percent of water, 0.01 to 0.02 percent of antioxidants, 3 to 5 percent of aluminum silicate wool, and 0.1 to 0.3 percent of infrared reflective paints.

Description

technical field [0001] The invention relates to a thermal insulation tube shell, in particular to a thermal insulation tube shell of expanded vitrified microspheres and a production method thereof. technical background [0002] Insulation shells are widely used in hot and cold liquids, hot and cold gases and other pipelines, in order to meet the requirements of heat preservation, cold preservation and heat insulation. [0003] At present, the thermal insulation shells on the market are mainly made of raw materials such as rock wool, glass wool, polyurethane, polyethylene rubber, and silica gel, which generally have the following defects: the thermal conductivity of the thermal insulation shell is high, the density is high, the thermal insulation effect is poor, and the Low tensile strength, poor aging resistance, small operating temperature range, easy to absorb water, easy to deform, short life and other defects. Contents of the invention [0004] In view of the above de...
