Color sand with high carbon black dispersity and preparation method thereof

Abstract

The invention relates to the technical field of color sand, in particular to color sand with high carbon black dispersity and a preparation method of the color sand. The color sand is prepared from the carbon black, the silicon dioxide, the lubricant, the dispersant, the maleic anhydride copolymer, the initiator and the organic solvent, and the carbon black is attached to the surface of the silicon dioxide, so that the acting force between the carbon black is reduced, carbon black agglomeration is reduced, the dispersity of the carbon black is improved, and the weather resistance of the outdoor lamp shell is improved; the outdoor lamp shell prepared from the color sand is uniform in color and has no color spots; the preparation method comprises the following steps: reacting silicon dioxide with a maleic anhydride grafted copolymer, reacting the maleic anhydride grafted copolymer with hydroxyl on the surface of the silicon dioxide under the action of an initiator to form a three-dimensional network structure on the surface of the silicon dioxide, attaching carbon black into the three-dimensional network structure, separating the carbon black, and reducing cohesion among the carbon black; therefore, the carbon black is difficult to agglomerate, and the dispersity of the carbon black is improved.

Description

Technical field [0001] This application involves the field of color sand technology, and more specifically, it involves a color sand and its preparation methods with high carbon black dispersal. Background technique [0002] In daily life, we often use various tools prepared by plastic, such as daily necessities, building supplies or decorative materials, etc., and most of the plastic performance is determined by its own nature, so that the use of plastic use is affected by the nature of plastic. Restrictions cannot meet the needs of people's daily life. Therefore, in order to change certain properties of plastic, such as molding processing performance, color, and stability, color sand will be added to the process of plastic processing molding to improve the performance of plastic. [0003] Outdoor light shells are suitable for street lights and outdoor decorative lights. When outdoor shells are prepared, it is usually used for carbon black sand, because carbon black has the adva...
