What is Flame retardant TEP?
Flame retardant TEP technology is to make non-flame retardant materials have flame retardant properties. It is a kind of material that is safe to burn or extinguish under certain conditions. The future development trend of the flame retardant effect of flame retardants is good, safe, and more environmentally friendly. Put a large part of the labor and resources to run technical research and development of flame retardants.
One, Surface modification
TEP has strong polarity and hydrophilicity, poor compatibility with non-polar polymer materials, and it is difficult to form a good bond and adhesion at the interface. In order to improve the adhesion and interface affinity between the polymer and the polymer, we will use a coupling agent for surface treatment, which is one of the most effective methods. Commonly used coupling agents are silanes and titanates. For example, the flame retardant effect of ATH treated with silane is very good, which can effectively improve the bending strength of polyester and the tensile strength of epoxy resin; and ATH treated with ethylene-silane can be used to improve cross-linked ethylene vinyl acetate copolymer The flame retardancy, heat resistance and moisture resistance. The titanate coupling agent and the silane coupling agent can be used together to produce a synergistic effect. After surface modification treatment, the surface activity of ATH is improved, the affinity with the resin is enhanced, the physical and mechanical properties of the product are improved, the processing fluidity of the resin is increased, the moisture absorption rate of the ATH surface is reduced, and the moisture absorption rate of the ATH surface is increased. Various electrical properties of flame-retardant products, and the flame-retardant effect is increased from V21 to V20.
Two, Ultra-fine
Flame retardant TEP has the advantages of high stability, low volatility, low smoke toxicity, low cost, etc., and is becoming more and more popular. However, its compatibility with synthetic materials is poor, and the amount of addition is large. Ultra-fineness is also considered from the aspect of affinity. It is precisely because of the different polarities of aluminum hydroxide and polymers that the physical and mechanical properties of its flame-retardant composite materials decrease. The ultra-fine and nano 3 Al(OH) enhances the interaction of the interface, can be uniformly dispersed in the matrix resin, and more effectively improves the mechanical properties of the mixture.
Three, Synergistic flame retardant with multiple flame retardants
In actual production and application, a single flame retardant always has one or another defect, and it is difficult to meet the higher and higher requirements with a single flame retardant. The compounding technology of flame retardant is to compound between phosphorus, halogen, nitrogen and inorganic flame retardants, or some kind of internal compounding, to seek the best economic and social benefits. The flame retardant compounding technology can combine the strengths of two or more flame retardants to complement each other in performance, reduce the amount of flame retardant used, and improve the flame retardant performance, processing performance and physical and mechanical properties of the material.
Four, cross-linking
The flame retardant properties of cross-linked polymers are much better than linear polymers. Adding a small amount of crosslinking agent during the processing of thermoplastics can make the plastic part of the network structure, which can improve the dispersibility of the flame retardant, which is conducive to the formation of carbon formation when the plastic is burned, improves the flame retardancy, and can increase the product’s Mechanical, heat resistance and other properties.
Five, microencapsulation
The application of microencapsulation to flame retardants is a new technology developed in recent years. The essence of microencapsulation is to pulverize and disperse the flame retardant into particles, encapsulate it with organic or inorganic substances to form a microcapsule flame retardant, or use a large inorganic substance as a carrier to adsorb the flame retardant on these inorganic substances. In the voids of the material carrier, a honeycomb microcapsule flame retardant is formed.
The microencapsulation of bromine-based environmentally friendly flame retardants has the following advantages:
- It can improve the stability of flame retardants;
- It can improve the compatibility of the flame retardant and the resin, so that the physical and mechanical properties of the material can be reduced;
- It can greatly improve the various properties of the flame retardant and expand its application range. VI. Nano flame retardant technology
Nanomaterials have the ability to prevent combustion. Add combustible materials as flame retardants. With the special effects of its scale and structure, you can change the combustible material’s combustion performance into the performance of the fireproof material. With the help of nanotechnology, the mechanism can be changed and the flame retardant performance can be improved. Due to the small size of the nanoparticle, the surface is important. It is the expression of the surface effect, volume, and size of the quantum tunneling effect, which is designed and manufactured for high-performance materials, using new ideas and methods to influence the characteristics of macroscopic quantum multi-function. The above six technologies are the latest research results of flame retardant technology. In the near future, it will apply more advanced technologies to certain flame retardants to provide a safer living environment.
