Description
Technical Field
The invention relates to a pearlescent pigment, in particular to a special flow mark-free pearlescent pigment for plastics and a preparation method thereof.
Background
Plastic articles with a colored appearance are becoming new and fashionable. In order to obtain a colored appearance, it is generally necessary to spray paint on the plastic substrate to achieve a beautiful and beautiful appearance. However, the spraying process has a series of problems of complex flow, high production cost, large environmental pollution, high spraying cost and the like.
Therefore, more and more manufacturers are seeking alternative spray techniques to give the product a bright, stylish appearance, giving the concept of spray-free. The spraying-free high polymer material and the effect pigment are matched and can be directly injected into various plastic accessories, so that plastic products with colorful appearances can be directly obtained, a paint spraying process is omitted, the harm to the environment is reduced, and the manufacturing cost is greatly reduced. The plastic spraying-free process comprehensively considers the problems of material recycling and environmental protection, and accords with the trend of green manufacturing (xu beng, Wan bin, Liuyun, and the like).
The preparation of spraying-free plastics by using pigments with special color effects such as mica pearlescent pigments and the like becomes popular. Because the pearl powder has rich and colorful colors, the pearl powder is easy to match various color effects, and can meet the requirements of different customers. However, when the flaky effect pigment is applied to injection molding in the plastic industry, problems such as flow marks, welding marks and the like can occur, and the attractiveness of the product is affected. The injection molding process can be improved through a rapid thermal cycle injection molding process (Wangculong, research and application of a rapid thermal cycle injection molding key technology [ D ]. Shandong university, 2011.), or a mold needs to be redesigned (Yangguang, Gaojun, Lishu, an injection mold for eliminating flow marks of spraying-free thermoplastic plastics [ P ]. CN201720299753.6,2017), but modification of powder is a more economic and effective mode on the premise of not changing the injection molding process. The main reason why the flake pigment generates flow marks and the like when applied to an injection molding process is considered to be that the particle size of the powder is large, and large shear resistance is caused (Wurongjia. analysis and study on cause of flow marks on the surface of an injection molded product [ D ]. university of south China Arganister, 3 months 2012).
The main focus of flake effect pigments applicable to the plastic injection molding industry is post-coating or mixing with fluorine-containing resin substances, but such post-coating or mixing is not uniform in handling (president, yojun, pupils, etc.. a strip-shaped aluminum pigment [ P ]. cn201610594818.x, 2016) with smooth and few flow marks on the surface.

In a preferred embodiment of the invention, the addition amount of the special flow-mark-free pearlescent pigment for plastics is 1% -10% of the addition amount of the plastics.
The "ordinary pearlescent pigment" (also referred to as pearlescent pigment substrate) used in the present invention is composed of the following components:
a: a substrate; b: a color effect layer; c: an anti-yellowing layer (which is an optional layer but preferably comprises this layer).
The substrate used to prepare the general pearlescent pigment in the present invention is preferably a flake material preferably selected from one or a mixture of more of natural mica, synthetic mica, flake silica, flake alumina, flake glass, flake iron oxide and flake aluminum powder.
In the present invention, the color effect layer may be a combination of materials that obtain various color effects together with the substrate by interference and refraction of light, and the combination may be a single-layer coated metal or nonmetal oxide or hydroxide, or a combination of multiple-layer coated metal or nonmetal oxide or hydroxide; the single-layer coated metal or nonmetal oxide may be a metal or nonmetal oxide having high refraction, preferably titanium dioxide, iron sesquioxide or a mixture thereof; the multilayer metal or non-metal oxide may be a metal or non-metal oxide or hydroxide with alternating high refractive index and/or a metal or non-metal oxide or hydroxide with low refractive index, preferably silica, alumina or mixtures thereof.
The plastics generally contain antioxidants and the like, and are phenolic substances with certain activity, which can react with substances of a pearlescent pigment color effect layer to turn yellow and affect the appearance during high-temperature treatment, particularly white pearlescent pigments. Therefore, a pigment having a white color in the bulk color needs to be subjected to an anti-yellowing treatment. For pigments having a dark bulk color such as iron oxide, this layer may be omitted, but may be included, because the powder itself is dark and not susceptible to yellowing.
The anti-yellowing layer is a material that is optically or thermally active and is generally selected to be stable in nature and to be non-optically active. In the present invention, it is preferable that the anti-yellowing layer is silicon dioxide, aluminum oxide, zirconium oxide, cerium oxide, aluminum phosphate, zinc phosphate, zirconium phosphate, aluminum phosphite, zinc phosphite, zirconium phosphite, or a compound produced by reacting the above substances, or a combination thereof. In the invention, the anti-yellowing layer can be coated with the anti-yellowing layer after the color coating layer is coated and calcined, and can be calcined again or not, or the anti-yellowing layer is coated after the color effect layer is coated, and then the anti-yellowing layer can be calcined or not according to requirements. For materials containing the above coating are also referred to herein as anti-pearlescence.
In the injection molding process of plastics, under the condition of a mold and an injection molding process which can obtain satisfactory injection molding effect after process adjustment, the problem of flow marks is easy to occur when pigments are added, and particularly, the phenomenon becomes more serious after the flaky effect pigments are added. In the invention, on the premise of not changing a mould, in order to obtain a satisfactory injection molding effect, the common pearlescent pigment is subjected to organic coating treatment, wherein the organic coating treatment is to coat a fluorine-containing coating capable of reducing the surface tension on the pearlescent pigment powder, and the fluorine-containing coating is composed of fluorine-containing segments and polyoxyethylene segments.
The common post-mixed organic coating is difficult to be uniformly dispersed with the powder, so that the powder obtained by in-situ polymerization has more uniform organic layer coating.
The special pearlescent pigment for plastic disclosed by the invention is characterized in that a fluorine-containing polymer coating is generated in situ on the surface of common pearlescent pigment powder, and the coating contains polyoxyethylene segments and fluorine-containing segments, so that the surface has a smaller friction coefficient, the shearing of the pigment powder in the plastic processing process can be reduced, the powder arrangement is promoted, and the flow marks and the weld marks are further reduced. The pearl pigment special for plastic comprises the fluorine coating and also comprises polyoxyethylene segments, and the part of the structure can improve the compatibility with the plastic, promote the dispersion, and improve or even eliminate the defects of flow marks, welding marks and the like under the combined action of the fluorine-containing segments.
The preparation method of the invention is to coat the polymer containing polyoxyethylene segment firstly and then coat the substance containing the fluorine segment, and also considers the water-oil double-hydrophobic property of the fluorine-containing substance. When the fluorine-containing fragment-containing substance is coated first and then the polyoxyethylene-containing fragment-containing substance is coated, there are problems that dispersion is difficult and coating is difficult, and a product having satisfactory effects cannot be obtained.
The invention obtains the fluoropolymer coating by in-situ polymerization on the surface of the common pearlescent pigment, so that the prepared special pearlescent pigment without flow marks for plastics can be applied to the plastic industry, products without leaving marks or fusion marks can be obtained, the optimal effect of preventing the flow marks is achieved, and powder is mainly distributed on the surface layer of the plastics and is regularly arranged due to the treatment of the fluoropolymer on the surface, thereby having obvious decorative effect.
