Description

Technical Field

[0002] Rubber-plastic insulation board is a kind of insulation material made of rubber and plastic, which is widely used in construction, refrigeration, air conditioning and other fields. It has excellent insulation performance, corrosion resistance, anti-aging, moisture resistance, environmental protection and other characteristics, and is widely used in various occasions that require insulation. Rubber-plastic insulation board is mainly made of rubber and plastic, among which rubber mainly provides toughness and impact resistance, while plastic provides good insulation performance and durability.

[0003] In the prior art, a foaming furnace is used as a foaming treatment device. In the production process of rubber-plastic insulation boards, a foaming furnace is often used to process and foam the rubber-plastic insulation boards. However, when the existing foaming furnace is actually used, a large amount of smoke will be generated during the foaming process of the rubber-plastic insulation boards, and the smoke will be discharged to the outside through the discharge port on the foaming furnace, resulting in the exhaust smoke not only polluting the environment, but also causing harm to the health of workers after inhaling the smoke for a long time. At the same time, a large amount of heat carried in the smoke is also discharged, resulting in excessive heat loss and a large amount of energy waste. Utility Model Content
