AI Technical Summary

Problems solved by technology

The main reason is that the adhesive used in insulation materials cannot meet the flame retardant performance
When running at high speed, the insulation material will fall off. After falling off, the adhesive surface will be exposed. If it encounters an open flame, it will be ignited, thereby expanding the scope of the fire and bringing great danger to passengers.

Embodiment 1

[0017] The thermal insulation composite material provided in this embodiment, the aluminum foil glass fiber cloth used, has flame retardancy, can isolate water vapor, prevent vehicles, such as: condensation on the inner surface of the air duct of a train, and prevent the growth of microorganisms such as mold.

[0018] The thermal insulation composite material provided in this example uses melamine resin foam produced by BASF Resin foam (also known as Insulation cotton), the material has a low density (8kg / m 3 ~11kg / m 3 ), low thermal conductivity, good thermal insulation performance, and good sound absorption performance.

[0019] The adhesive provided in this embodiment is a flame-retardant adhesive, mainly composed of 60% to 70% oily pressure-sensitive adhesive (such as: Y-150 pressure-sensitive adhesive, purchased from Changzhou Xiecheng Adhesive Co., Ltd.) and 30% to 40% Flame retardant (PY-1 type, purchased from Huzhou Ruigao New Material Co., Ltd.).

Abstract

The invention relates to antiflaming gum which comprises 60%-70% of oily pressure-sensitive adhesive and 30%-40% of fire retardant. The antiflaming gum is taken as an adhesive and is used for preparing a composite together with aluminum foil glass fabric and melamine resin foam. The antiflaming gum provided by the invention has the advantages that the oxygen index is more than or equal to 32, the flame retardant property can meet TBT3237 standard and DIN5510, EN45545, BS6853 and NFP130 standards, the fireproof performance is excellent and the running safety of vehicle at high speed can be effectively ensured. A test proves that the sticking service life of the antiflaming glue applied to the heat-insualting cotton made of resin foams can reach 20 years or above.

Description

technical field [0001] The invention relates to an adhesive, in particular to an adhesive with a flame-retardant effect and a thermal insulation composite material made of back glue. Background technique [0002] When a vehicle (such as a high-speed train) is operating at a high speed (such as: 350 km / h), in order to keep the vehicle in a state of safe operation, not only the key components of the vehicle system need to ensure normal operation, but also for each small component Or some auxiliary materials are also crucial, especially in the fire performance of the material. [0003] At present, among the thermal insulation materials with adhesive backing used by major domestic and foreign manufacturers on high-speed trains, there is no enterprise that can provide thermal insulation materials with adhesive backing with good flame retardancy. The main reason is that the back glue used in insulation materials cannot meet the flame retardant performance. When running at high s...
