Description
Technical Field
[0001] The invention relates to a production method and a production device, and in particular to a production method and a production device for making black masterbatch by using recycled carbon black obtained from waste tires or rubber. Background Art
[0002] Please refer to Figure 1 As shown in the figure, it is a structural diagram of carbon black. According to the global automobile market, about 30 million waste tires are estimated to be produced each year, and about 120,000 waste tires are produced in Taiwan, China. However, there is still a lack of effective recycling and reuse of waste tires to form carbon black and waste recycling, which makes it impossible to achieve an environmentally friendly circular economy and reduce the generation of waste and garbage. The birth of a new environmentally friendly carbon reduction material that uses recycled carbon black to make black masterbatch is impossible. Carbon black 6 is composed of more than 95% carbon, and a small amount of oxygen, sulfur, nitrogen and ash. It is a very light and fine black powder. The particle size of carbon black primary particles 63 is about 10-500nm. The carbon black primary particles 63 are tightly connected into a ball string, which is an aggregate 62 (aggregate), which is the primary structure of carbon black; and the primary structure will be adsorbed to each other by Van der Waals force to form an agglomerate 61 (agglomerate), and finally after granulation, it is the popular carbon black particles on the market. Electron microscopy shows that their particle sizes and structural complexity are significantly different. Since carbon black 6 does not exist as a single primary particle 63, the particle size of carbon black 6 is often expressed by specific surface area (e.g. Figure 1As shown), in general, furnace carbon black has few surface functional groups, and most carbon black is neutral to weakly alkaline. However, no one on the market has invented a method that can adjust the functional groups on the surface of carbon black through special surface modification treatment methods according to the needs of different applications, and then adjust the pH value of carbon black to achieve the most ideal carbon black performance; generally, carbon black is an important black coloring raw material. Carbon black is a product obtained by treating hydrocarbons as raw materials through thermal cracking or incomplete combustion. It is divided into different specifications. Since there are many types of carbon black, in order to distinguish them, the American Society for Testing and Materials International (ASTM) has standardized the naming method of standardized carbon black. Carbon black for rubber is generally classified and named according to ASTM D1765 standard. The naming method consists of four parts: the vulcanization speed (N / S), the specific surface area (1-9), and the structural complexity, which is composed of an English letter N or S representing the vulcanization speed and three Arabic numerals representing the carbon nitrogen surface area range and the different carbon black structure levels; the commonly used rubber grade carbon blacks include N220, N330, N660, N990 and other specifications. According to the different functions and uses of carbon black, it can be roughly classified into: waste tire and rubber application carbon black, pigment carbon black and conductive carbon black; general black masterbatch uses 100% virgin pigment carbon black (Virgin Carbon black has a small primary particle size and a high oil absorption capacity. Due to its high cost, no one in the market uses the recycled carbon black, which has a large primary particle size, low oil absorption, low tinting power, no commercial value, unstable source and quality, and different surface properties from pigment carbon black. Since it is not easy to mix and disperse with plastic carriers and has low tinting power, no one has produced it into a black masterbatch or black glue with appropriate physical properties and processability through a device, which greatly reduces its practicality. This is what technicians in the field and consumers are eager to break through. Summary of the invention

Generally, carbon black is an important black coloring raw material, and black masterbatch uses 100% virgin carbon black.

[0060] Remark
[0061] *1 The carbon footprint calculation table is a relative reference value based on existing manufacturer data and may vary depending on the process.
[0062] And as Figure 8 Shown is a distribution diagram, which is a distribution diagram of carbon black nitrogen adsorption surface area and oil absorption value.
[0063] like Fig. 9 Shown is a comparison of three carbon black agglomerates.
[0064] The particle size distribution of the recovered carbon black agglomerates is that the particle size of the recovered carbon black D50 is higher than that of N330. Large particles may affect the processability and dispersibility. If there are too many impurities, the physical properties will be affected. The present invention uses screen grading and filtering from coarse to fine to remove oversized carbon black particles and reduce impurities.
[0065] Therefore, a new black masterbatch can be obtained by mixing pigment carbon black, recycled carbon black and dispersant.

When the recycled carbon black accounts for about 1 / 3 to 1 / 2 of the total carbon black, appropriate physical properties can be obtained; if 5-10% of the total amount of dispersant is added, the wettability of the black mass can be increased, and appropriate physical properties and processability can be obtained. Since the use of coloring materials is calculated based on the added amount in the total formula, the comparison method between the black masterbatch 101 and the black glue 102 is to use the black masterbatch 101 in a ratio of 4% and 1% of the total composition to develop color under a resin carrier as a hue comparison condition for full shade (Fullshade) and tint shade (Tint shade); the black masterbatch 101 or the black glue 102 of the present invention is formed by uniformly mixing a preset ratio of carbon black and a resin carrier, and can be used as a coloring material for shoe materials such as midsole plastic foam or rubber bottom material; in order to reduce waste and reuse it, waste tires can be used to generate recycled carbon black, and the recycled carbon black can be used as a mixed raw material to make a black masterbatch, which is applied to shoe materials to achieve a new type of environmentally friendly waste reduction material with a circular economy.
