Description
Technical Field
The invention belongs to the field of plastic additives, and particularly relates to a transparent nucleating agent containing an inorganic pigment and an organic pigment and a product thereof.
Background
The polypropylene is one of five general purpose plastics in the world, has good mechanical property, no toxicity, low relative density, heat resistance, chemical resistance, easy processing and molding, excellent flexibility and dielectric property and low price, and becomes the most active variety with the fastest growth speed and the most active new product development in the five general purpose plastics. At present, more and more functional polypropylene appears in various market fields, including high-rigidity polypropylene, high-temperature-resistant polypropylene, transparent polypropylene and other high-value-added products. Polypropylene is widely used, but since it is a semi-crystalline polymer, there are two-phase structures, i.e., crystalline and amorphous regions, with fewer nucleation sites throughout the interior. Under the influence of no external factors, the crystal forming speed is very low, the polypropylene crystal is used, the number of the formed spherulites is small, the formed spherulites are thick, and the incident visible light is scattered and refracted, so that the product has poor light transmittance and poor appearance aesthetic feeling, and the application of the product in the fields of packaging, medical appliances, electronic products, daily necessities and the like is limited.
In recent years, due to the remarkable increase of the requirement on transparency, the modification by adding a nucleating agent has become an important direction for the modification research of polypropylene materials. The polypropylene nucleating agent is divided into an alpha nucleating agent, a beta nucleating agent and a gamma nucleating agent according to different crystal forms, and the alpha nucleating agent is most common and most widely applied. The beta nucleating agent is less in variety, such as stearates, aromatic amides, certain condensed ring compounds having a quasi-planar structure, and the like. Sorbitol nucleating agent is widely applied to transparent modification of polypropylene at present, and belongs to alpha nucleating agent, the nucleating agent is found in 70 years of 20 th century, and the Milladn company has already provided fourth generation sorbitol nucleating agent (MilladNX8000) at present. After the polypropylene is modified by the nucleating agent, the original characteristics of the polypropylene can be continuously maintained, the surface gloss and the light transmittance of the polypropylene can be improved, the advantages of light weight, low price, sanitation, high temperature resistance, processing and forming and the like of the polypropylene are also inherited, and the polypropylene becomes a typical transparent material with good rigidity and toughness balance and high heat distortion temperature.
With the continuous expansion of the application field of polypropylene, the demand of colored polypropylene is more and more increased. For coloring polypropylene, inorganic pigments and organic pigments can be used. However, since the inorganic pigment and the organic pigment are different in particle size and other physical and chemical properties, they are difficult to stably exist in the same system, and it is difficult to use the inorganic pigment and the organic pigment in combination with polypropylene as a main component. Thus, the existing coloring of polypropylene generally uses an inorganic pigment and an organic pigment separately, thereby avoiding the above-mentioned drawbacks. For organic pigments, which may also be used as nucleating agents when present in certain concentrations, for example, CN105860273A discloses a transparent polypropylene composition based on an organic pigment nucleating agent, which composition contains 0.04X 10－6－2.8×10－6Organic pigment in weight portion, wherein the organic pigment acts as nucleating agent, and the composition is added with 0.04-0.5 portion of transparent agent.
Inorganic pigments and organic pigments have advantages and disadvantages, for example, inorganic pigments have advantages of good thermal stability, good weather resistance, excellent light stability and low price, but inorganic pigments have poor coloring power and are not vivid in color. Organic pigments have the advantages of strong coloring power, vivid color and complete color spectrum, but are inferior to inorganic pigments in heat resistance and weather resistance. It follows that if both inorganic and organic pigments are used in a pigmented system, a complementary advantage is achieved and the colouring effect can be greatly increased.
However, the currently used polyethylene products have single color and no vivid color due to separate use of inorganic pigments and organic pigments, or the products fade after a certain storage time, which results in a great decrease in vivid color. Although TW200730595 discloses a coating composition containing both inorganic and organic pigments, the composition includes polyacrylic resin, inorganic pigment, and organic pigment, that is, the inorganic and organic pigments need polyacrylic resin as a carrier to be stably present. CN1377388A discloses a sorbitan ester treated pigment for plastic applications, which is a pigment obtained by reacting a monoazo pigment such as pigment yellow 191: 1, with the addition of 1-10% by weight of a sorbitan ester which can improve the color of pigment yellow 191: 1 tinting strength and dispersibility.
In addition, the addition of pigment in the system may affect the light transmission and gloss of polyethylene products, so how to balance the color vividness, low haze and gloss of polypropylene products is a difficult problem which plagues the polypropylene industry.

The transparent nucleating agent composition containing the inorganic pigment and the organic pigment in a specific ratio has no influence on the processing of the polymer, and is unexpected to those skilled in the art because the dispersion aspects of the inorganic pigment and the organic pigment have part of performance conflict, but after the inorganic pigment and the organic pigment are adjusted to a certain ratio, the performance conflict is avoided, and the processing is smoother.
Detailed Description
The method comprises the steps of selecting an inorganic pigment and an organic pigment, adjusting the weight ratio of the inorganic pigment to the organic pigment, and mixing the inorganic pigment and the organic pigment with a transparent nucleating agent to obtain different transparent nucleating agent compositions. In the process of screening the inorganic pigment, if the melting point of the inorganic pigment is too high, the pigment is not uniformly dispersed in the transparent nucleating agent, and the color is not uniform directly, while the solubility of the organic pigment is also a very critical factor, because the water solubility or fat solubility of the organic pigment is too high, the vividness of the color is not vivid along with the contact of the polymer product with water or grease, and the glossiness is also influenced to a certain extent.
The following is a detailed description by way of specific examples. The inorganic pigments and organic pigments used in the examples are commercially available products, and the transparent nucleating agents NA-98 and NA-2 were produced by the applicant himself, wherein the chemical name of NA-98 is (1,3:2,4) -bis (3, 4-dimethylbenzylidene) -D-sorbitol, and the chemical name of NA-2 is (1,3:2,4) -bis-O- (p-chlorobenzylidene) -D-sorbitol.
The following test methods were used for the performance of polypropylene articles:
haze: test according to GB/T2410-
Gloss: testing according to GB/T8807-
The method for detecting the color vividness comprises the following steps: the film of the polypropylene article was placed in a sealed container in the presence of ultraviolet lamp irradiation, and after irradiation for 7 days, the film was taken out and evaluated for color vividness by 10 experts. The evaluation criteria used by the experts are as follows: 0 point, the vividness of the color is the same as that of a new product; 1 point, light fading; 2, obviously fading; and 3 points, severe fading. The average value of the points determined by the experts is used to evaluate vividness of the color.

According to the weight ratio of the formula in the table 1, the organic pigment and the inorganic pigment are fully mixed, and then the mixture is fully mixed with the transparent nucleating agent to obtain the transparent nucleating agent composition.
For example, when the transparent nucleating agent: inorganic pigment: the weight ratio of the organic pigment is 1000000: 20000: at 100 (example 12), 200g of the inorganic pigment was thoroughly mixed with 1g of the organic pigment, and then thoroughly mixed with 10 kg of the transparent nucleating agent NA-98 to give a transparent nucleating agent composition.
The transparent nucleating agent composition and polypropylene (atactic homo-polypropylene, the melt index MI is 20g/10min) are fully mixed, extruded and granulated (the temperature is 230 ℃), wherein the adding amount of the transparent nucleating agent composition is 0.25 percent of the weight of the polypropylene. Then preparing the plastic film for performance test.

TABLE 2 Properties of Polypropylene articles Using NA-98 clear nucleator compositions
From the above experimental results, when the transparent nucleating agent used: inorganic pigment: the weight ratio of organic pigments falls within 1000000:5000-20000: in the range of 10 to 100 (examples 1 to 12), the resulting polypropylene article had both vivid color and retained vivid color even when stored for a long period of time under severe environments, and at the same time, had very low haze, indicating that the polypropylene article had excellent transparency, and in addition, the article had excellent gloss. However, as is clear from the test results of examples 13 to 16 (increased amount of inorganic pigment used) and examples 17 to 20 (increased amount of organic pigment used), when the amount of organic pigment and inorganic pigment used exceeds the above ratio, haze of the product is increased, and further, color vividness is affected, and when the compounding ratio of examples 13 to 20 is used, the product is discolored to some extent with time. When the organic pigment alone was used without using the organic pigment (example 21), the vividness of the color of the product was insufficient, and there was a large increase in haze. When the organic pigment was not used and only the inorganic pigment was used (example 22), the discoloration of the article was relatively severe. When the amount of the transparent nucleating agent in the transparent nucleating agent composition is insufficient (example 23), the haze of the article is affected, and more severe discoloration may occur.
