Problems solved by technology

[0002] At present, the method used for pipeline insulation is generally to wrap glass cloth on the pipeline, paint or coat galvanized steel plate or aluminum plate. This method is complicated in process, time-consuming, poor in sealing and waterproof effect, can only be used once, and has a short life. Now there is another kind of insulation material which is made of vacuum aluminized polyester film and glass cloth. This kind of material has good sealing and waterproof effect and is easy to use in construction, but it is prone to aging under the action of solar radiation and high temperature. The phenomenon causes the aluminum layer to fall off, which affects the use effect of this insulation material

Abstract

The composite heat-insulating and protecting material is made of aluminum foil and fireproof fiber fabric, and the fireproof fiber fabric is mixed fiber felt of fireproof cotton yarn in 30-70 wt% and glass fiber 30-70 wt%. The composite heat-insulating and protecting material has high heat-isolating and sealing effect, is fireproof, radiation resistant and long in service life, and may be used in making heat-insulating and protecting casing for apparatus and pipeline and capable of being assembled and disassembled easily.

Description

technical field [0001] The invention relates to a material, in particular to a thermal insulation protection material, in particular to a composite thermal insulation protection material. Background technique [0002] At present, the method used for pipeline insulation is generally to wrap glass cloth on the pipeline, paint or coat galvanized steel plate or aluminum plate. This method is complicated in process, time-consuming, poor in sealing and waterproof effect, can only be used once, and has a short life. Now there is another kind of insulation material which is made of vacuum aluminized polyester film and glass cloth. This kind of material has good sealing and waterproof effect and is easy to use in construction, but it is prone to aging under the action of solar radiation and high temperature. The phenomenon causes the aluminum layer to fall off, which affects the use effect of this thermal insulation material. Invention content: [0003] In order to solve the short...
