黑色母粒的组成部分

   黑色母粒的组成部分有哪些
　　1、颜料或染
　　颜料又分为有机颜料与无机颜料 常用的有机颜料有：酞菁红、酞菁蓝、酞菁绿、耐晒大红、
　　大分子红、大分子黄、永固黄、永固紫、偶氮红等 常用的无机颜料有：镉红、镉黄、钛白粉、炭黑、氧化铁红、氧化铁黄等
　　2、载体
　　载体是黑色母粒的基体，专用色母一般选择与制品树脂相同的树脂作为载体，两者的相容性最好，但同时也要考虑载体的流动性。
　　3、分散剂
　　促使颜料均匀分散并不再凝聚，分散剂的熔点应比树脂低，与树脂有良好的相容性，和颜料有较好的亲和力。最常用的分散剂为：聚乙烯低分子蜡、硬脂酸盐。
　　4、添加剂
　　添加剂。如阻燃、增亮、抗菌、抗静电、抗氧化等品种，除非客户提出要求，一般情况下黑色母粒中并不含有上述添加剂。
　　1、黑色母粒的组成?
　　组成黑色母粒的材料有：A.碳黑; B.碳黑载体; C.碳黑润湿剂; D.碳黑分散剂; E.其他加工助剂。
　　2、黑色母粒所用碳黑的种类?
　　按照国际分类，我国有三十多个品种。主要分为橡胶用和非橡胶用两大类。碳黑是橡胶补强剂，能有效地提高橡胶轮胎的耐 磨性以及橡胶制品的物理机械性能;在非橡胶用碳黑中，真正能作为黑色母粒的碳黑只有几种。
　　以槽法碳黑在塑料中应用最为广泛，这主要由于其来源丰富，纯度高，粒径小。这其中，又分为高色素碳黑(粒径9-17nm)， 中色素碳黑(粒径18-25nm)和低色素碳黑(粒径26-37nm)。
　　由于碳黑品种不同，价格差异很大。碳黑粒子由于其本身具有多活泼性，很少以原生粒子存在，几乎都以一定范围粒径的团 聚粒子存在。
　　3、碳黑载体是怎么回事?
　　载体就是承载碳黑的物质。一般塑料制品使用什么原料，载体就使用什么原料。这样制造的黑色母粒与塑料原料相容性较好 。
　　如：PS(聚苯乙烯)塑料制品，其使用的黑色母粒载体就是PS。对于聚乙烯塑料制品，载体就是聚乙烯。
　　但是，一般选用LDPE(高压聚乙烯)，因为LDPE承载碳黑能力最强，且加工性能好。而其他聚乙烯HDPE和LLDPE只能制造低浓 度黑色母粒。
　　对于PP(聚丙烯)塑料制品，只能使用PP和LDPE为载体的黑色母粒，但不能使用HDPE和LLDPE及其他塑料为载体的黑色母粒。当然也有用回收料做载体的黑色母粒。
　　4、为什么碳黑需要润湿剂?
　　碳黑比重约2g/cm，由于碳黑粒径很小，表现密度就很小，显得蓬松，似乎很轻。要顺利加工，就必须先将碳黑润湿。
　　润湿剂的选择非常关键。为降低成本，大量使用白油或石蜡之类的产品的企业不在少数，这会严重影响所加工制品的强度

 What are the components of black masterbatch?

 1. Pigments or dyed pigments can be divided into organic pigments and inorganic pigments. Commonly used organic pigments include: phthalocyanine red, phthalocyanine blue, phthalocyanine green, light fast red, macromolecular red, macromolecular yellow, permanent yellow, permanent purple, azo red, etc. Commonly used inorganic pigments include: cadmium red, cadmium yellow, titanium dioxide, carbon black, iron oxide red, iron oxide yellow, etc.

 2. The carrier is the matrix of black masterbatch.

 3. Dispersants make pigments disperse evenly and stop agglomerating. The melting point of dispersants should be lower than that of resins, and they have good compatibility with resins and good affinity with pigments. The most commonly used dispersants are polyethylene low molecular wax and stearate.

4. Additives. Such as flame retardant, brightening, antibacterial, antistatic, antioxidant and other varieties, unless required by customers, generally black masterbatch does not contain the above additives.

 1. What is the composition of black masterbatch? The materials that make up the black master batch are: a. carbon black; B. carbon black carrier; C. carbon black wetting agent; D. carbon black dispersant; E. other processing AIDS.

 2. What kind of carbon black is used in black masterbatch? According to international classification, there are more than 30 varieties in China. Mainly divided into two categories: rubber use and non-rubber use. Carbon black is a rubber reinforcing agent, which can effectively improve the wear resistance of rubber tires and the physical and mechanical properties of rubber products; Among the non-rubber carbon blacks, there are only a few carbon blacks that can really be used as black masterbatch. Trough carbon black is the most widely used in plastics, which is mainly due to its rich sources, high purity and small particle size. Among them, it is divided into high pigment carbon black (particle size 9-17nm), medium pigment carbon black (particle size 18-25nm) and low pigment carbon black (particle size 26-37nm). Due to the different varieties of carbon black, the price varies greatly. Carbon black particles rarely exist as primary particles because of their own reactivity, and almost all exist as aggregated particles with a certain range of particle sizes.

3. What is the carbon black carrier? A carrier is a substance that carries carbon black. What raw materials are used for general plastic products, and what raw materials are used for carriers. The black master batch made in this way has good compatibility with plastic raw materials. For example: PS (polystyrene) plastic products, the black masterbatch carrier used is PS. For polyethylene plastic products, the carrier is polyethylene. However, LDPE (High Pressure Polyethylene) is generally selected because LDPE has the strongest capacity of carrying carbon black and good processability. However, other polyethylene HDPE and LLDPE can only produce low-concentration black masterbatch. For PP (polypropylene) plastic products, only black masterbatch with PP and LDPE as carriers can be used, but HDPE, LLDPE and other plastics as carriers cannot be used. Of course, there are also black master batches with recycled materials as carriers.

 4. Why does carbon black need a wetting agent? The specific gravity of carbon black is about 2g/cm. Because the particle size of carbon black is very small, its apparent density is very small, and it seems fluffy and light. In order to process smoothly, carbon black must be wetted first. The choice of wetting agent is very important. In order to reduce costs, many enterprises use products such as white oil or paraffin in large quantities, which will seriously affect the strength of processed products.
