Low smoke zero halogen calcium silicon intumescent flame retardant system is a new type of trade name Casico TM developed in the 90s of last century, its basic composition is: ethylene-propylene copolymer, surface treatment chalk and silicone resin elastomer composition, from the composition of the system to break through the traditional ammonium polyphosphate (APP) as acid source, pentaerythritol (PER) as carbon source, melamine or stage derivatives as gas source
。 Developed according to this principle (HFLS) halogen-free low-halogen flame retardant cable plastic, the flame retardant role is mainly filled with aluminum and magnesium hydroxide and other flame retardant filler, the flame retardant releases crystal water during combustion, absorbs a large amount of heat, thereby inhibiting the temperature rise of the complex, delaying the thermal decomposition of the polymer, and reducing the combustion rate
.
This type of cable requires a lot of inorganic flame retardant materials to fill, which greatly reduces the extrusion processability of the material, as well as mechanical properties, and the cable is easy to cause lateral cracking during use, which greatly loses the application value
of cable products.
In recent years, it has been found that under combustion conditions, such as the surface of molded parts with an increase in the concentration gradient of flame retardants, the flame retardant effect
can be improved.
According to this principle, a small amount of polysiloxane can be added to the
plastic.
In this way, when burned, the silicon organisms enriched on the surface of the molded parts can obtain high flame retardancy
.
Casico TM low-smoke zero halogenated calcium silicon intumescent flame retardant plastic designed by Shenghua Cable Group, its expansion model flame retardant mechanism is EBA (ethylene-propylene copolymer) as acid source and carbon source, CaCO3 is the gas source, this new three sources in the storage conditions containing SI components to achieve a better match, overcome the shortcomings
of the traditional intumescent flame retardant system moisture absorption components migration.
Among them, SFR is a transparent, viscous polysiloxane polymer, which is partially interconnected and merged into the polymer by interpenetrating the polymer network, which greatly reduces the fluidity
of silicon.
Shanghai Shenghua Cable Group cooperated with Shanghai Jiao Tong University to establish a school-enterprise cooperation scientific research center to carry out comprehensive research on flame retardant materials; In collaboration with users and experts such as China Flame Retardant Society and Sinopec, China Flame Retardant R&D Center was established to promote the industrialization and marketization
of flame retardant products.
When using SFR as a flame retardant, only a very low dosage is required to meet the flame retardant requirements and maintain the original performance
of the substrate.
Therefore, if the safety and fire level is relatively high, as long as the amount is increased, excellent flame retardancy and smoke suppression can be achieved, and the elongation, mechanical properties, etc.
can meet the requirements, and the target requirements
of halogen-free low-smoke flame retardant cables can be truly realized.
The new type of material cable developed by Shenghua Cable Group has the function of engaging in mineral oil, and is a long-awaited cable product in marine, locomotive, vehicle and oil production departments, which is a strong cooperation and support
for exporting foreign projects.
