With the rapid development of China's economy, the consumption of high-molecular materials such as plastics and rubber has increased rapidly. Plastic and rubber products are widely used in civil, military, construction, power and transportation industries. However, most of these plastics have low oxygen index and are easy to burn in the air. Therefore, it is difficult to apply them to industries that have special requirements for fire prevention without effective measures. In order to realize its application, adding flame retardant is a convenient, simple, reliable and easy to implement method. Now flame retardants have become one of the important additives for plastics processing. From the perspective of output and dosage, it has become the second plastic additive only after plasticizers. According to the existence state of flame retardant, it can be divided into solid powder and liquid flowing water, among which solid powder accounts for more than 95%.
The amount of flame retardants used in the country in 2013 exceeded 1.2 million tons, and it is growing at a rate of 10-15% each year. With the increasing use of flame retardants, the problems of flame retardants have also become apparent, first of all, the issue of environmental protection, then the issue of flame retardant efficiency, and then the issue of labor. At present, when enterprises in China use flame retardants, there are still problems such as simple equipment, serious running and risk, and primitive emission. The dust is particularly prominent. Some people have done statistics. During the use of 1 ton of flame retardants, at least 2% of the flame retardants are consumed through the process of batching, mixing, feeding and processing, which means that there will be at least 22,000 tons of flame retardants every year The helpless discharge flew into the air and the workplace, polluting other products and even the atmospheric environment.
The flame retardant masterbatch can solve all the problems mentioned above, and it will not generate dust, but also make the flame retardant dispersed more evenly in the material, and improve the flame retardant efficiency. It can also automatically suck to realize unmanned operation.
Flame retardant masterbatches, also known as flame retardant masterbatches, are fire retardant masterbatches. With the continuous deepening of the plastic flame retardant industry, and the consciousness of environmental protection and the continuous improvement of product quality requirements, a higher demand has arisen. More specific, more efficient forms of flame retardants. Flame retardant masterbatch is mainly divided into functional flame retardant masterbatch and functional flame retardant masterbatch according to the different customer groups. The functional flame retardant masterbatch mainly reflects the rationality of the flame retardant masterbatch formula and the scientific application. It can not only complete the flame retardancy of the material, but also achieve the various mechanical properties of the material. The masterbatch manufacturer's in-depth understanding of various flame retardant plastic properties and deep application practice knowledge are mainly applicable to equipment and products that cannot directly use flame retardant powders such as injection molding and extrusion profile products, reducing costs. The effective flame retardant masterbatch mainly reflects the higher the concentration of effective flame retardant, the better. It relies on advanced equipment and reasonable choice of flame retardant and carrier. It is mainly suitable for modified engineering plastics and cable materials. Twin-screw pelletizing enterprises to increase production and reduce costs.
Compared with flame retardants, flame retardant masterbatches have the following characteristics:
High flame retardant efficiency: According to a reasonable formula, the flame retardant masterbatch is extruded and granulated through the organic combination of flame retardant, synergist, dispersant and carrier. Well, after mixing with plastic, they are more dense and uniform, so that each flame retardant molecule can exert flame retardant effect. Compared with the flame retardant powder with the same formula, the flame retardant efficiency is increased by more than 10%, and the flame retardant powder cannot Evenly mixed with plastic particles, the flame retardant properties of the product are inconsistent, and secondary mixing is required in the later stage to increase labor.
Easy to use, environmentally friendly and dust-free: most of the flame retardant masterbatch are spherical or cylindrical particles, which are exactly the same size as ordinary plastic particles, making it easier to weigh and add, and can realize automatic suction or electronic weight feeding, the whole process No dust and ash, clean and hygienic, reduce volatile waste, improve working environment, improve work efficiency, easy to use.
Good compatibility with resin: Reasonable flame retardant masterbatches are specially designed according to the different plastic resins they will be added to in the future. They are specially treated to solve their compatibility with the resin and make them in the resin. Even when the amount is large, it will not cause problems such as delamination, frost, and white spots.
Reduce costs and increase added value of products: Due to the continuous advancement of technology and equipment, the functions and performance of flame retardant masterbatches have also continuously improved. In many aspects, direct mixing with materials can produce products that meet all performance requirements, greatly reducing This reduces product cost, increases product added value, and greatly saves labor costs. In today's difficult labor and rising labor costs, how to reduce labor, achieve continuous production, and improve enterprise efficiency has become another major issue that companies have to face in the process of development.
