With the rapid development of China's economy, the use of plastic materials such as plastics and rubber has grown rapidly, mainly based on polyethylene, polypropylene, polystyrene, nylon and ABS, PET, PBT, EVA, PVC and various rubbers. Plastic rubber products are widely used in various industries such as civil, military, construction, electric power and transportation. However, since most of these plastics have the characteristics of low oxygen index and easy combustion in air, it is difficult to apply them to industries with special requirements for fire prevention without effective measures. In order to achieve its application, the addition of flame retardant is a convenient, simple, reliable and easy to implement method. Nowadays, flame retardant has become one of the important auxiliaries for plastic processing. In terms of output and dosage, it has become the plastic auxiliary after plasticizer. According to the existence state of the flame retardant, it can be divided into a solid powder form and a liquid flow form, wherein the solid powder form accounts for more than 95%. In 2013, the national use of flame retardants exceeded 1.2 million tons, and the annual growth rate was 10-15%. As the amount of flame retardant is getting larger and larger, the problems of flame retardant are also highlighted. The first is environmental protection, followed by the problem of flame retardant efficiency, and then the problem of labor. At present, when enterprises in China use flame retardants, there are still problems such as simple equipment, serious running, serious emissions, and raw emissions. The dust is particularly prominent. Some people have done statistics. Every 1 ton of flame retardant in the process of use, after the ingredients, mixing, feeding and other processes, at least 2% of the flame retardant loss, which means that there will be at least 22,000 tons of flame retardant per year. The helpless discharge of the air flies into the air and the workplace, polluting other products and even the atmosphere. The flame retardant masterbatch can solve all the above problems, neither generating dust flying, but also making the flame retardant more uniform in the material, improving the flame retardant efficiency; and also automatically sucking the material to realize unmanned operation. Flame retardant masterbatch, also known as flame retardant masterbatch, fireproof masterbatch, is a higher demand with the continuous deepening of the plastic flame retardant industry, the awareness of environmental protection and the continuous improvement of product quality requirements. A more specific, more efficient form of flame retardant. The flame retardant masterbatch is mainly divided into functional flame retardant masterbatch and functional flame retardant masterbatch according to the customer group in which it is used. The functional flame retardant masterbatch mainly reflects the rationality and scientific application of the flame retardant masterbatch formulation, which can not only complete the flame retardancy of the material, but also realize the various mechanical properties of the material are not reduced, reflecting the resistance The masters of the masterbatch have a deep understanding of the characteristics of various flame retardant plastics and a deep application of practical knowledge. They are mainly suitable for equipments and products such as injection molding and extrusion of profile products that cannot directly use flame retardant powders, reducing costs. The functional flame retardant masterbatch mainly reflects the higher the concentration of the effective flame retardant. The better the equipment is based on advanced equipment and reasonable flame retardant and carrier selection. It is mainly suitable for modifying engineering plastics and cable materials. Twin-screw granulation companies increase production and reduce costs. Relative to the flame retardant, the flame retardant masterbatch has the following characteristics: High flame retardant efficiency: The flame retardant masterbatch is based on a reasonable formula, through the organic combination of flame retardant, synergist, dispersant and carrier, after being uniformly mixed and kneaded, extrusion granulation, its dispersibility Well, after mixing with plastic, they are more transparent and uniform, so that each flame retardant molecule can exert flame retardant effect. Compared with the same formula of flame retardant powder, the flame retardant efficiency is increased by more than 10%, and the flame retardant powder cannot be cured. Evenly mixed with plastic particles, the flame retardant properties of the products are inconsistent, and it is necessary to mix twice in the later stage to increase labor. ï¬ Easy to use, environmentally friendly and dust-free: Most of the flame retardant masterbatch is spherical or cylindrical pellets, which are just the same size as ordinary plastic pellets, making it easier to weigh and add, and can realize automatic suction or electronic weighing feeding. No dust and ash, clean, hygienic, reduce volatile waste, improve working environment, improve work efficiency, easy to use. Flame retardant masterbatch Good compatibility with resin: reasonable flame retardant masterbatch is specially designed according to the plastic resin added to it in the future. It is specially treated to solve its compatibility with the resin and make it in the resin. Even if the amount of addition is large, there are no problems such as delamination, blooming, and white spots. Reduce costs and increase the added value of products: Due to the continuous advancement of technology and equipment, the function and performance of flame retardant masterbatch are also continuously improved. In many aspects, direct blending with materials can produce products that meet all performance requirements, greatly reducing The product cost increases the added value of the product while greatly saving labor costs. Today, when labor is difficult and the cost of labor is rising, how to reduce labor, achieve continuous production, and improve enterprise efficiency have become another major issue that must be faced in the development of enterprises.
