Embodiment 1

[0031] The prefabricated 0.1mm thick galvanized steel sheet with the adhesion-promoting layer is entered into an oven at 80° C. for preheating. Toughening agent: curing agent = 100: 1: 8: 5: 10) is poured on it (to ensure that the thickness of the foam is 20mm), and enters the composite insulation board continuous production line together with the aluminum foil as the other surface layer for foaming and curing. Finally, according to the specifications, it is cut into a certain length of composite board and trimmed and packaged. This product is used as an air duct plate for the air supply duct of the central air conditioner in a large building.

[0032] The surfactant is silicone oil, the foaming agent is 141b, the toughening agent is polyethylene glycol, and the curing agent is 10% sulfuric acid.

Embodiment 2

[0034] The prefabricated 0.5mm thick tinplate plate with the tackifying layer is entered into an oven at 80°C for preheating, and after preheating, the proportioned mixture (expandable phenolic resin: surfactant: foaming agent: Toughening agent: curing agent = 100: 2: 1: 8: 4) is poured on it (to ensure that the thickness of the foam is 20mm), and enters the composite insulation board continuous production line together with the aluminum plate as the other surface layer for foaming and curing. Finally, according to the specifications, it is cut into a certain length of composite board and trimmed and packaged. This product is used as an air duct plate for the air supply duct of the central air conditioner in a large building.

[0035]The surfactant is an EL emulsifier, the foaming agent is a hydrocarbon foaming agent, the toughening agent is polyethylene glycol, and the curing agent is 10% p-toluenesulfonic acid.

Embodiment 3

[0037] Put the prefabricated 0.15mm thick color steel plate with an adhesion-promoting layer into an oven at 80°C for preheating. Toughening agent: curing agent = 100: 3: 6: 7: 12) is poured on it (to ensure that the thickness of the foam is 20mm), and enters the composite insulation board continuous production line together with the aluminum foil paper as the other surface layer for foaming and curing. Finally, according to the specifications, it is cut into a certain length of composite board and trimmed and packaged. This product is used as an air duct plate for the air supply duct of the central air conditioner in a large building.

[0038] The surfactant is silicone oil, the foaming agent is 141b, and the toughening agent is polyvinyl alcohol. The curing agent is 13% phosphoric acid.

Abstract

A steel face type phenolic aldehyde heat preservation composite board and the manufacturing method and application thereof relate to a warming plate, particularly a steel face type phenolic aldehyde heat preservation composite board and the manufacturing method and application thereof, which combines the advantages of the traditional galvanized sheet iron wind pipe and combined wind pipe, have good heat preservation effect, widely used in the pipe of the central air conditioner, such as the heat preservation work shop, the clean air condition house, the large exhibition hall, the gymnasium, the high-rise building, the high level villa, which are provided with an upper layer, a tackified layer, the phenol formaldehyde foam insulation layer and the metal lower layer. The tackified layer is arranged between the upper layer and the phenol formaldehyde foam insulation layer, the thickness of the upper layer is 0.1-0.5 mm, the thickness of the phenol formaldehyde foam insulation layer is 20-100mm, the thickness of the metal lower layer is 0.05-0.5 mm. The continuous production method or the batch production method is used.

Description

technical field [0001] The invention relates to a class of thermal insulation boards, in particular to a class of steel-faced phenolic thermal insulation composite boards and a manufacturing method and application thereof. Background technique [0002] As an important part of the ventilation and air-conditioning system in modern buildings, ventilation ducts are continuously updated with the development of science and technology, and the types of duct systems are constantly updated, such as: traditional galvanized iron ducts, inorganic glass steel ducts, Composite lightweight insulation air duct, etc. Composite lightweight insulation air duct core materials include rock wool, extruded polystyrene board, phenolic foam, polyurethane foam, etc. Although the composite rock wool has the advantages of good thermal insulation performance and beautiful appearance, it is easy to absorb water, and the exposed glass fiber is harmful to the human body, and the thermal insulation effect ...
