Abstract
Provided are a compound functional black coloring agent and a preparation method thereof. The compound functional black coloring agent is prepared from, by weight, 0.1-0.7 part of inorganic nano-materials, 6-8 parts of color black, 0.1 part of dispersing agent, 0.1-0.15 part of lubricating agent, 0.01 part of antifoaming agent, 0.1-0.2 part of emulgator and 0.2 part of coupling reagent. The preparation method comprises the following steps of 1, pre-dispersion, wherein nano particles, the dispersing agent and the lubricating agent are stirred at high speed for 1-3 minutes, the coupling reagent is added to be stirred for 1-2 minutes, and then the color black is added to be stirred for 5-8 minutes; 2, ball-milling dispersion or ultrasonic dispersion; 3, emulsification treatment, wherein the emulgator, the antifoaming agent and a proper amount of process water are added for low-speed stirring. According to the compound functional black coloring agent, the nano-material, namely, the modified color black is adopted, and the advantages of being good in dispersion performance, high in dyeing property, low in production cost, stable in property and the like are achieved. According to the preparation method, the operating process is easy and convenient.
Description
technical field [0001] The invention relates to a composite functional black dyeing agent and a preparation method thereof, in particular to a composite functional black dyeing agent modified with nanomaterials to pigment carbon black and a preparation method thereof. Background technique [0002] Phenolic resin is a polymer material that is polymerized with phenol and formaldehyde as raw materials under the condition of acidic catalyst (or basic catalyst). Its production process is stable and easy to operate, the price of raw materials is low, and it has many advantages such as good heat resistance, electrical insulation, corrosion resistance, low smoke generation, and product dimensional stability. Therefore, phenolic molding compound (commonly known as bakelite powder) with phenolic resin as the main raw material is widely used in many fields such as household appliances, household cooking utensils, aerospace, and automobile industry. Among the many phenolic molding prod...
