For the color materials used in the color masterbatch, pay attention to the matching relationship with the plastic raw materials and additives. If the matching is good, it can achieve a multiplier effect with half the effort. If the match is not good, the two will not be well integrated, not only will it fail to achieve the desired effect, but other side effects will occur. The specific selection points are as follows:
(1) The dispersion and tinting strength of the masterbatch should be good. When the pigment is unevenly dispersed, it will affect the appearance of the product; when the coloring power of the pigment is poor, the amount of the pigment will increase and the material cost will increase. The same colorant has different dispersibility and tinting power in different resins, so this point should be paid attention to when choosing a colorant. The particle size of the pigment is also related to the dispersibility. The smaller the particle size of the pigment, the better the dispersibility and the stronger the coloring power.
(2) The pigment can not react with resin and various additives, and has strong solvent resistance, low migration and good heat resistance. In other words, the color masterbatch cannot participate in various chemical reactions. For example, carbon black can control the curing reaction of polyester plastic, so carbon black material cannot be added to polyester. Due to the high molding processing temperature of plastic products, the pigments should not decompose and change color under the conditions of molding heating temperature. Generally, inorganic pigments have better heat resistance, and organic pigments and dyes have poor heat resistance. This point should be paid attention to when choosing pigments.
(3) Other properties of the color masterbatch should be understood. For example, for plastic products used in food and children's toys, the color should be non-toxic; plastic products used in electrical appliances should be selected with good electrical insulation. ; For outdoor plastic products, color materials with good weathering resistance should be selected.
It can be seen from this that the collocation of the raw materials and additives used in the color masterbatch depends on what the product is applied to. The application is different, and the collocation is also different. It cannot be generalized.
