Novel heat-insulating coldness-preserving material

Abstract

The invention discloses a novel heat-insulating coldness-preserving material. According to the novel heat-insulating coldness-preserving material, a middle basic layer is made from inflaming-retarding modified PVCCaCO3, wherein a first composite aluminum foil heat-insulating reflecting layer is attached to the upper surface of the inflaming-retarding modified PVCCaCO3, and 10-100mm sound absorption foam with high softness and elasticity is attached to the lower surface of the inflaming-retarding modified PVCCaCO3. The novel heat-insulating coldness-preserving material makes the most of the characteristics that the modified PVCCaCO3 is high in strength, resistant to a low temperature and good in tenacity, and an aluminum coating is high in reflectance and resistant to the low temperature and damp, thereby having the advantages of high coldness-preserving heat-insulating properties, high strength, high resistance to shocks, high resistance to the low temperature, high resistance to damp and the like.

Description

technical field [0001] The invention relates to a new type of high heat insulation and cold preservation material which has high strength, elasticity, oxidation resistance and corrosion resistance, high heat insulation and cold preservation effect, and is economical and durable. Background technique [0002] With the current global warming, in the environment of low-carbon economy, the country vigorously encourages and promotes energy conservation and emission reduction, and the cold preservation of pipelines is a very important part. The cold insulation materials commonly used in the market are mainly foam glass and rock wool. The thermal conductivity of foam glass itself is low, but its disadvantages are that it is expensive, difficult to construct, and it is not tightly attached to the inner wall of the pipe, and there is no reflective layer, which affects the cold insulation effect; materials such as rock wool have neither reflective function nor Moisture resistance is ...

AI Technical Summary

Problems solved by technology

The thermal conductivity of foam glass itself is low, but its disadvantages are that it is expensive, difficult to construct, and it is not tightly attached to the inner wall of the pipe, and there is no reflective layer, which affects the cold insulation effect; materials such as rock wool have neither reflective function nor Moisture-proof is easy to oxidize, and the cold-insulation effect is poor; therefore, we have developed a new type of high-insulation and cold-insulation material with high strength, elasticity, oxidation resistance and corrosion resistance, high heat insulation, cold insulation effect, economical and durable
