preparation example Construction

[0047]According to an embodiment of the present invention, there is also provided a preparation method for implementing the above-mentioned environment-friendly composite plastic with pearlescent effect, including:

[0048] Raw material pretreatment: dehumidify, crush and sieve each component in the raw material;

[0049] Raw material preparation: weigh each component in the raw material according to the ratio;

[0050] Raw material premixing: physically mix the components in the raw material;

[0051] Extruder processing: feed the raw materials into the extruder for melt homogenization, devolatilization treatment and extrusion granulation.

[0052] It should be noted that the processing steps of the extruder can also be completed in different equipments for melting homogenization, devolatilization treatment and extrusion granulation respectively. The extruder configuration should not limit the preparation method of the present application.

[0053] As a specific solution, ...

Embodiment 1

[0066] The components and proportioning ratio of Embodiment 1 are shown in Table 2.

[0067] Its specific preparation process is as follows: using the same equipment and operating conditions as the comparative example, the stirring speed is 2000rpm, and the time is divided into 2 minutes and 3 minutes (sampling observation in the middle). Adopt the same equipment with comparative example, and process condition is also similar. The maximum temperature and the template temperature were lowered by 10°C each. The screw speed was adjusted to 150 rpm.

Abstract

The invention discloses environment-friendly composite plastic with a pearlescent effect and a preparation method thereof. The environment-friendly composite plastic is prepared from six types of rawmaterials including: base resin, modified resin, a macromolecular compatilizer, a toughening plasticizer, filler and auxiliaries. The base resin is a microcosmic phase separation multi-block high-molecular copolymer, a macromolecular block of the base resin at least comprises a rubber chain segment and a plastic chain segment, the phase domain micro-region of the rubber chain segment has a size value range of 15-80 nanometers; the modified resin is one or more of polyolefin resin, styrene resin, polyester resin and polyformaldehyde resin. The preparation method comprises the steps of raw material pretreatment, raw material preparation, raw material premixing and extruder processing. The composite plastic and the preparation method thereof have the beneficial effects that the safe and environment-friendly composite plastic with a pearlescent effect, excellent physical and mechanical properties and processability and moderate cost is provided.

Description

technical field [0001] The application relates to the field of polymer materials, in particular to an environmentally safe composite plastic with a pearlescent effect and a preparation method thereof. Background technique [0002] In the 1950s, people used the shiny fish scales of natural fish scales and mixed them with transparent resin to make beautiful pearlescent plastics. However, the raw material source of this fish scale is unstable, and the quantity is difficult to meet the requirements of industrial production. Later, people invented artificial pearlescent pigments, which are salts of heavy metals, such as strontium oxychloride, lead arsenate, lead carbonate, and lead phosphate. Although they can be supplied to industrial production, they cannot meet the environmental protection requirements of later social development. [0003] In the 1960s, DuPont of the United States invented the coating of flaky muscovite with titanium dioxide, which can be used as a pearlescen...
