Description

Technical Field

[0001] The utility model relates to the technical field of phenolic foam boards, and particularly relates to a heat-insulating and fire-proof composite phenolic foam board. Background Art

[0002] The phenolic foam board is made of phenolic foam material and is a new generation of heat-insulating, fire-proof and sound-insulating material. The phenolic foam material belongs to a high-molecular organic rigid aluminum foil foam product and is formed by foaming thermosetting phenolic resin. It has the characteristics of light weight, fire resistance, non-combustion when encountering an open flame, no smoke, non-toxic, no dripping, a wide service temperature range (-196~+200°C), no shrinkage and embrittlement at low temperature. Since the phenolic foam has a high closed-cell rate, its thermal conductivity is low (it can be lower than 0.030w / mk), its heat-insulating performance is good, and it has certain water resistance and water vapor permeability. It is a good heat-insulating and energy-saving material and an ideal heat-insulating material for HVAC refrigeration projects.

For the heat-insulating and fire-proof composite phenolic foam board of the utility model, when in use, the reinforcing mechanism can improve the strength of the phenolic foam board body through the square cross block. The square cross block is square in structure when in use, and rubber strips are cross-connected inside. When in use, it can improve the overall strength of the phenolic foam board body, making it have strong bonding property and strong anti-bending ability. The protective layer can improve the anti-ultraviolet ability of the phenolic foam board body when in use and can improve the service life of the phenolic foam board body when in use, avoiding the influence on the phenolic foam board body caused by long-term ultraviolet irradiation.

[0033] Further, the reinforcement component 6 includes multiple first reinforcement silk threads 601 and multiple second reinforcement silk threads 602;

[0034] The multiple first reinforcement silk threads 601 and the multiple second reinforcement silk threads 602 are cross - combined. Protective layers 12 are provided on the outer surfaces of the first protective film 3 and the second protective film 4. The protective layers 12 are used to protect the first protective film 3 and the second protective film 4. Side films 5 are provided on the four sides of the first phenolic foam board 1 and the second phenolic foam board 2. The side films 5 are adhesively connected to the first phenolic foam board 1 and the second phenolic foam board 2. The composite layer includes a fire - resistant cotton 7, a sound - insulating cotton 8 provided on one side of the fire - resistant cotton 7, and a heat - resistant rubber plate 9 provided on the surface of the sound - insulating cotton 8. The connecting member includes multiple convex blocks 10 and multiple grooves 11. The multiple convex blocks 10 are fixedly connected to the surface of the composite layer of the second phenolic foam board 2, and the multiple grooves 11 are opened on the surface of the composite layer of the first phenolic foam board 1. Adhesive glue is provided on the inner walls of the multiple grooves 11. After the first reinforcement silk threads 601 and the multiple second reinforcement silk threads 602 are combined, they form a fishing - net shape.

[0035] For a technical solution provided by the present utility model, when arranging the foam boards provided in this application, remove the side films 5 on the four sides of the first phenolic foam board 1 and the second phenolic foam board 2, and install the first phenolic foam board 1 and the second phenolic foam board 2 on the wall.
