Problems solved by technology

However, there are some disadvantages in the use of these materials: 1. After collision, they are volatile, and then they will enter the heat insulation layer, making them unable to achieve the effect of heat preservation and heat insulation.
2. The price is high, and it is easy to attract the attention of some criminals. After theft, the insulation material will lose its protection, which will not only affect the insulation effect, but also accelerate the aging of the insulation material
3. The thermal conductivity of metal is high, although it can prevent rain and look beautiful, it has no heat insulation effect
4. Although it has certain anti-corrosion properties, its service life is not very long
5. Due to the uniqueness of the current thermal equipment, irregular equipment shapes and valves are inconvenient to construct, and the appearance is not beautiful, and poor construction will cause heat loss

Abstract

The invention discloses a magnesium steel protection pipe sleeve, which is manufactured by coating slurry on 6 to 9 layers of glass fiber cloth, wherein the slurry is prepared from the following raw materials in part by weight: 20 to 30 parts of magnesia, 22 to 30 parts of brine, 10 to 20 parts of ferrisulphas, 0.5 to 1.5 parts of titanium white, 1 to 3.5 parts of mica powder, 1 to 3 parts of talcpowder and 0.05 to 0.1 part of coupling agent. The invention also discloses a manufacturing method of the magnesium steel protection pipe sleeve. Products manufactured by the method have the characteristics of environmental friendliness, high water repellency, excellent thermal insulation property and good durability and aesthetic property.

Description

technical field [0001] The invention relates to a magnesium steel protective pipe sleeve and a manufacturing method thereof, belonging to the technical field of anti-corrosion materials. Background technique [0002] With the rapid development of my country's modern industry, more and more attention has been paid to thermal insulation, so thermal insulation projects have also greatly increased. Looking back on the development history of thermal insulation, from the initial perlite and diatomite to the current popular use of aluminum silicate wool and rock wool, due to their light weight, high temperature resistance, low thermal conductivity, convenient construction, good thermal insulation effect and reasonable The price is more and more widely used, but there are also shortcomings, and it has a certain degree of water absorption, so the outer protective layer must have good water resistance. [0003] The early outer protective layer was usually cement plaster, glass cloth,...
