In the field of fireproof materials, fireproof masterbatch stands out for its excellent flame retardant performance, and this outstanding performance largely depends on its high content of high-quality flame retardant.
High content of flame retardant is the key material basis for achieving excellent flame retardant effect. When fireproof masterbatch is added to the polymer matrix, a large amount of flame retardant can quickly take effect in the initial stage of fire. For example, some high-quality flame retardants containing phosphorus and nitrogen will decompose and produce non-flammable gases such as phosphoric acid and ammonia when heated. These gases quickly form a dense protective film on the surface of the polymer, isolating the contact between oxygen and the polymer, thereby effectively inhibiting the combustion reaction. Due to the high content of flame retardant in fireproof masterbatch, these flame-retardant gases can be continuously released, so that the protective film can be maintained for a long time, greatly reducing the possibility of fire spreading.
The chemical structure and characteristics of high-quality flame retardants themselves determine their efficient flame retardant mechanism. Take aluminum hydroxide flame retardant as an example. It will decompose at high temperature and absorb a lot of heat, thereby reducing the temperature around the polymer and making it difficult for the polymer to reach the temperature conditions required for combustion. At the same time, the aluminum oxide produced by decomposition is a high-temperature resistant substance that will cover the surface of the polymer, further enhancing the effect of blocking oxygen. Moreover, high-quality flame retardants have good compatibility with the polymer matrix and can be evenly dispersed in it. This ensures that when a fire occurs, the flame retardant can play a role in the entire polymer material simultaneously, avoiding the situation of local flame retardant failure. For example, after adding fireproof masterbatch containing a high content of high-quality flame retardant to some engineering plastics, an effective flame retardant protection system can be formed both on the surface and inside of the material, so that the material can show excellent flame retardant performance when facing flames.
In addition, the synergistic effect of high-quality flame retardants with high content should not be ignored. Different types of flame retardants cooperate with each other in the fireproof masterbatch to produce the effect of "1+1>2". For example, when halogen flame retardants are used in combination with antimony flame retardants, halogen flame retardants release hydrogen halide gas when heated, and antimony flame retardants react with hydrogen halide to form antimony trihalide. Antimony trihalide has higher density and stability, can cover the polymer surface more effectively, further strengthen the flame retardant barrier, and thus achieve a more excellent flame retardant effect, providing a solid and reliable guarantee for the protection of life and property safety, and playing an irreplaceable and important role in many industries with extremely high fire protection requirements such as construction, electronic appliances, etc.
