New technology of flame retardant agent
Since 1908, G. A. Engelard etc with chlorine reaction made by natural rubber flame retardant chlorinated rubber, pioneered by chemical methods of flame retardant polymer first, especially the demand of polymer industry is developing rapidly in recent 40 years, flame retardant technology got rapid development, has developed many efficient and new type of flame retardants. With the development of flame retardant technology, a lot of new technology of flame retardant has emerged.
The microencapsulation technology of new technology of flame retardant is applied to flame retardant. It is a new technology developed in recent years. The essence of the microcapsules, after smashing flame retardants is dispersed particles, organic matter or inorganic matter to cyst, the formation of microcapsule flame retardants, or large with the surface of inorganic substances as the carrier, carrier will adsorption in the inorganic flame retardants, the gap form cellular decay capsule flame retardants.
Microcapsule technology can prevent the migration of flame retardant, improve the flame retardant effect, improve the thermal stability and change many advantages, such as dosage forms of component between compound with efficiency and manufacture multifunctional flame retardant materials is also very good. Our country is currently exploring, such as the microencapsulated red phosphorus mother material developed by hunan plastics institute, successfully applied in PR, PP, PS, ABS resin, the flame retardant effect is good; The chemical research institute of anhui has developed microencapsulated dibromophenyl phosphate and microencapsulated chloroprene - 70, which also has a good effect.
The superfine technology of the new technology of flame retardant: inorganic flame retardant has the advantages of high stability, low volatility, low toxicity and low cost, and it is becoming more and more popular. However, because of its poor compatibility with synthetic materials and large additions, the mechanical properties and heat resistance of the materials have been reduced. Therefore, inorganic flame retardants are modified to enhance their compatibility with synthetic materials, and decrease the amount of inorganic flame retardants is one of the development trends of inorganic flame retardants.
At present, the superrefinement and nanometer of aluminum hydroxide (ATH) are the main research and development direction. The large amount of addition of ATH will reduce the mechanical properties of the material and then fill it through the micro-refinement of ATH, which will be the effect of the stiff-particle plasticizing enhancement, especially the nano-level material.
Because the fire retardant function is controlled by the chemical reaction, and the same amount of flame retardants, the smaller the particle size, the bigger the surface area, the better the flame retardant effect.
Tris(2-butoxyethyl)phosphate(TBEP)Use
This Product Is Flame Retardant Plasticizer, Mainly Used For Polyurethane Rubber, Cellulose, Polyvinyl Alcohol And Other Flame Retardant And Plasticized, With Good Low Temperature Characteristics. Use Of Tris(2-butoxyethyl)phosphate(TBEP) For Flame Retardant Plasticizers And Processing Aids For Rubber, Cellulose And Resins. It Is Recommended For Use In Acrylonitrile-Based Rubbers, Cellulose Acetate, Epoxy Resins, Ethylcellulose, Polyvinyl Acetate And Thermoplastic And Thermoset Polyurethane. Phosphobutyrate (TBEP) Is Also Used As A Defoamer (Antifoam Agent) In Coatings, Detergents And Textiles. Has A Good Low Temperature Characteristics. This Product Can Also Be Used For Nitrocellulose, Ethyl Cellulose, Acrylic Plasticizer, Can Make Products With Transparency And Good Resistance To UV Performance.
Ultrafine is considered from the aspects of affinity, is because of aluminium hydroxide and polymer polarity is different, thus leading to as flame retardant composite material processing technology and the physical and mechanical properties of the drop, ultrafine nano ATH, due to the enhanced interfacial interaction; The mechanical properties of the mixture can be improved more evenly in the matrix resin. Will use super refining technology of flame retardant polymer organic polymer of the advantages of good flexibility, low density, easy processing and high strength and hardness of the inorganic filler, heat resistance, not easily deformation height, shows strong vitality.
Flame retardant surface modification technology of new technology: inorganic flame retardant with strong polarity and hydrophilic, with non polar polymer compatibility is poor, difficult to form good combination and adhesive interface. In order to improve the adhesion and interface affinity of the polymer, it is one of the most effective methods for surface treatment.
The commonly used coupling agent is silane and titanate, such as the ATH flame retardant effect after silane treatment, can effectively improve the flexural strength of polyester and the tensile strength of epoxy resin.
The ATH can be used to improve the flame retardation, heat resistance and moisture resistance of crosslinked ethylene-vinyl acetate copolymer. Titanate coupling agent and silane coupling agent can be used and can produce synergistic effect.
In addition, alkyl ketone isocyanate and phosphate titanate are used as coupling agents for the surface treatment of the ATH. After dealing with the surface modification of ATH surface activity improved, increased the affinity between the resin and improved the physical and mechanical properties of products, increase the processing fluidity of the resin, reduces the ATH surface moisture absorption rate, improve the flame retardant products of the various electrical properties, and can be to increase the flame retardant effect of V - grade 1 to grade V - O.
