Problems solved by technology

Although the higher the usage amount of the pearlescent substance, the better the pearlescent effect of the prepared container, the usage amount of the pearlescent substance cannot be increased arbitrarily, because when the usage amount of the pearlescent substance exceeds 10wt%, Incompatibilities with the main components will occur, resulting in defective containers

Embodiment 1

[0013] An example 1 of the pearlescent composition of the present invention includes 0.5 parts by weight of red pigment (Red Colorant, RC), 1 part by weight of pearlescent component, and the rest of polyester component. The pearl luster component includes a first component and a second component which are used in an amount of 0.5 parts by weight but of different materials. The first component is polypropylene (Polypropylene, PP), and the second component is silicone rubber (SR). The polyester component is polyethylene terephthalate (PET).

[0014] "Chroma and Gloss Measurement"

[0015] Example 1 was injection-molded into a pearlescent container with a capacity of about 500ml and a pearlescent effect, and the chromaticity of the pearlescent container was measured with an optical color difference instrument purchased from Datacolor Company, model 600TM, and was purchased from BYK-Gardner The company's gloss machine with a model of micro-gloss 60° measures the gloss of the pea...

Embodiment 2～6

[0017] Embodiments 2-6 are similar to the embodiment 1, except that the pearlescent materials used in the first component and the second component are different. The pearlescent materials actually used in Examples 2-6 are recorded in Table 1. Measure the chroma and gloss of the pearl luster containers prepared in Examples 2-6, and record them in Table 1. Among them, the TPX used in Examples 2, 4, and 6 was purchased from Mitsui Chemicals, the product model is MX002, and it is a commercial product with polymethylpentene as the main component.

[0018]

[0019]

Embodiment 7～12

[0025] Examples 7-12 are similar to Examples 1-6, except that the pearlescent component is used in an amount of 10 parts by weight, and includes the first component and the second component in an amount of 5 parts by weight respectively. The materials used for the first component and the second component of Examples 7 to 12 are listed in Table 3. The chroma and glossiness of the pearl luster containers prepared in Examples 7-12 were measured and recorded in Table 3.

Abstract

The invention discloses a pearlescent composition. In a total weight of 100 parts by weight, the pearlescent composition comprises 1 to 10 parts by weight of a pearlescent component and the balance ofa polyester component, wherein the pearlescent component comprises at least two of a polyolefin material, a silicone rubber material, a polymethylpentene material and a polymethyl methacrylate material. The pearlescent composition provided by the invention comprises two or more of the pearlescent materials, and can improve the chroma and gloss of a prepared pearlescent container under the limitation of the existing usage. In addition, when the pearlescent composition comprises three or more of the pearlescent materials, the chroma and gloss can be further improved, and if the pearlescent component comprises the silicone rubber material, the chroma and the gloss of the prepared pearlescent container can be improved, and simultaneously, the pearlescent container is endowed with smoother sense of touch.

Description

technical field [0001] The invention relates to a plastic and polymer composition, in particular to a pearlescent composition suitable for making plastic containers with pearlescent effect. Background technique [0002] There are many PET plastic containers made of polyethylene terephthalate (PET) in daily life. This kind of PET plastic container is widely used as containers for various purposes such as cosmetic containers, bath products containers, and food containers. In order to improve the texture of products and consumers' willingness to purchase, and to distinguish them from other competitors' products, many manufacturers often use special containers with pearlescent effects to hold their products. The aforementioned container with pearlescent effect is processed from a pearlescent composition capable of producing pearlescent effect. Compared with ordinary containers, the containers made of the pearlescent composition have a dazzling luster that can attract consumers...
