Introduction to Phenolic board
Phenolic board can be made of phenolic foam concrete material and is a kind of high-molecular organic hard aluminum foil foam economic product, which is made of thermosetting phenolic resin. It is widely used in phenolic insulation boards in developed countries. According to statistics and literature, in the United States, 40% of fireproof, thermal insulation and soundproof materials are phenolic resins. In the UK, Western Europe and the Middle East, it is stipulated that new construction projects should give priority to using phenolic foam insulation materials.
The construction departments in France and Northern Europe believe that only phenolic foam insulation materials have good fire resistance. Phenolic foam insulation materials are also widely used in public buildings and high-rise buildings in Russia and Eastern Europe. Japan has even issued a decree that "phenolic foam should be used as a standard flame-retardant material for buildings".
Phenolic board is known as the "King of Insulation Materials" and is a new generation of heat insulation material. The utility model has the characteristics of light weight, fire resistance, non-combustion over open flames, no smoke, no toxicity, no dripping, etc., and has a wide range of applicable temperatures. Phenolic foam type economy, as a new type of energy-saving building material that is information secure and green, has its advantages recognized by the personnel of the building and fire protection management departments. Phenolic foam was used for insulation in early missiles and rockets. It is widely applied in fields such as high-rise buildings, transportation, shipping, aviation, and aerospace technology.
In the field of insulation technology development for pipeline systems in petroleum universities, chemical engineering, etc., research on pipe shell products that can be cut with phenolic insulation boards is also widely applied. Phenolic thermal insulation composite products are widely used in large-scale embedded systems, A-level fireproof thermal insulation systems, comprehensive thermal insulation and decoration systems for building walls, fireproof door interlayers, color steel sandwich panel houses and other fields.
To enhance the performance indicators of phenolic boards and reduce their brittleness, all phenolic board manufacturers are committed to the research on the modification of phenolic boards. Composite modified phenolic board is a commonly used modified product of phenolic board. Adding a composite interface agent or grid mortar to the surface of phenolic board not only eliminates the defect of slag falling but also significantly enhances the strength and toughness of the phenolic board, making its fire resistance rating more in line with the non-combustible standard. The structure of phenolic board mainly consists of the bonding layer, insulation layer, plastering layer, decorative layer and accessories.
The bonding layer is a component of architectural engineering design, located between the bottom layer and the surface layer structure system. Its primary function is to firmly bond the upper and lower layers together with cementitious materials. The fillers are mainly sourced from inorganic substances. In order to avoid and reduce the heat loss of steam turbines to the environment and resources in our country, in the insulation engineering material layer laid on the outside of steam turbines and pipelines, it is mainly used as a filler for the development of rock wool fibers and through a certain amount of organic matter, moisture, adhesives, etc. The surface layer should be coated with lightweight functional coatings, such as decorative mortar, decorative mortar or water-based exterior wall coatings with good breathability, to maintain the lightweight characteristics of phenolic panels and enhance their aesthetic appeal.
