Phenolic board insulation and fire protection coexist

Phenolic sheets have the functions of fire resistance, smokelessness, insulation, etc. These functions can be well performed by a video displayed by a manufacturer of phenolic fireproof panels called “Yada”. The video content is such that a 3 cm thick phenolic Fireproof Board is applied to the person's face and the other side of the phenolic board is continuously fired with a 1400 degree Celsius flame spray gun. After a few minutes, the phenolic board was still not deformed and melted, and the face on the side of the board was not damaged. I don't know, I believe that everyone can easily see the upper hand of the phenolic board. From this point of view, the development prospect of the phenolic board is bound to be broad!

The phenolic board is not contradictory to heat preservation and fire prevention. The phenolic board is a fireproof and heat insulation material originally used in air conditioning and aerospace. It can be applied to exterior insulation systems through a series of functional improvements. Compared with other insulation systems, this system has excellent fire protection performance; at the same time, its thermal performance is superior, the thermal conductivity is low, and the thermal insulation effect is obvious. Although the price is slightly higher, the producers are still optimistic about the prospect of the phenolic board.

Some experts have questioned this. “Combustion function” refers to “all physical and chemical changes that occur when a building material burns or encounters fire”. Class A and Class B3 represent “non-combustible” and “flammable” respectively, and Class B2 represents “flammable”. However, because the definition of combustion grade is very professional, the old and new scales are different, it is difficult to directly correspond to the detailed materials, which makes it difficult for many design staff to make it clear.

In the "Destruction of Fire Prevention and Control of Building Engineering", it is necessary to use materials of Class A combustion function for the construction of insulation materials for civil buildings, and according to the Temporary Delimitation of Fire Protection for Exterior Buildings and Exterior Walls of Civil Buildings, the height is greater than 60 meters. For residential buildings less than 100 meters, the combustion function of the insulation materials should not be lower than B2 (B2 is allowed). It can be seen that in the field of professional technology, the fire prevention problem of wall insulation is controversial.
The rise of phenolic board makes the insulation and fire prevention not contradictory

In recent years, people's requirements for building materials can be said to be "energy-saving and emission-reducing, low-carbon food", and in terms of insulation materials, people want to save energy and want to prevent fire. However, in the past, the insulation materials, the heat preservation machine can have good fireproof performance, and the fire protection function is good, and the heat preservation and fire prevention seem to be a contradiction. It is difficult to be comprehensive. So is there a material that can resolve this contradiction and achieve the best insulation and fire protection?
