Problems solved by technology

[0004] The traditional polystyrene foam has good thermal insulation performance, but its main problem is that the maximum operating temperature is 70°C, which is quite close to the design temperature (60-65°C) of the winter air-conditioning water supply system.
Moreover, it is very easy to shrink, melt, and produce drops when exposed to fire. When it is applied to the central air-conditioning water pipe insulation system, after a certain period of operation, the polystyrene insulation shell will be deformed to varying degrees, and even the same as Pipe detachment phenomenon, the main reason is poor heat resistance
The water supply of the air conditioning system sometimes exceeds 70°C, and the application is greatly restricted

Abstract

The invention belongs to the technical field of heat preservation material production, and discloses a heat preservation tube shell with heat preservation and fire resistance. The heat preservation tube shell is prepared from the following raw materials in parts by weight: 30-40 parts of polystyrene particles, 25-30 parts of resin, 20-25 parts of a phosphorus-based flame retardant, 20-25 parts ofan inorganic environment-friendly flame retardant and 3.5-4.2 parts of a curing agent. The heat preservation tube shell provided by the invention has various good properties, and can be widely appliedto hot-cold water pipes, air conditioner pipelines, solar water heater water pipelines, heating thermal pipelines and liquefied natural gas pipelines and other pipeline heat preservation systems.

Description

technical field [0001] The invention belongs to the technical field of heat-insulating material production, and in particular relates to a heat-insulating tube shell with heat-insulating and fire-proof performance and a production method thereof. Background technique [0002] In the trend of building energy saving and green building, the domestic central air-conditioning, solar water heater and other industries are facing huge opportunities and challenges. Large-scale landmark buildings, CBD business districts, shopping malls and supermarkets, and civil buildings have higher and higher energy-saving requirements for central air-conditioning systems and solar water heater systems. [0003] When the central air-conditioning system and solar water heater water pipe system are running, they need to consume a lot of energy, and their energy consumption accounts for about 60% of the total energy consumption. Therefore, the air-conditioning system and solar system need to save ener...
