Problems solved by technology

[0006] However, there is no fully biodegradable plastic masterbatch at present. Some users dye by pumping pellets, which is time-consuming and laborious, and causes material performance degradation; some users simply use ordinary non-degradable plastic masterbatch for coloring, which brings The problem that fully biodegradable plastics are mixed with non-degradable plastic components affects the degradation rate

Embodiment 1

[0049] A fully biodegradable plastic color masterbatch, comprising 30% of pigment, 10% of protein powder, 10% of urea, 0.1% of aluminate, 4.9% of erucamide and 45% of PHB calculated by weight percentage.

[0050] Preparation:

[0051] Step A. put the amount of pigment and protein powder into the reactor, and stir at a high speed at 100°C-110°C for 10-30 minutes to remove the moisture therein;

[0052] Step B. Add the urea into the reactor, mix at high speed for 5-15 minutes, let the protein powder soften and disorder;

[0053] Step C. Then add aluminate and mix at high speed for 5-15 minutes, so that the pigment and protein powder become hydrophobic;

[0054] Step D. Finally, add erucamide and PHB, mix at high speed for 1-5 minutes, and obtain a mixture after discharging.

[0055] Step E. Melt and blend the mixture through a twin-screw extruder, extrude and granulate, cool and dry to obtain the fully biodegradable plastic masterbatch. The temperature zones of the extruder a...

Embodiment 2

[0057] A fully biodegradable plastic color masterbatch, including 5% of pigment, 50% of starch, 1% of ethylene glycol, 1% of silane coupling agent, 0.2% of stearic acid and 42.8% of PLA calculated by weight percentage;

[0058] The preparation method is the same as in specific example 1.

Embodiment 3

[0060] A fully biodegradable plastic masterbatch, including 25% pigment, 45% protein powder, 7% glycerin, 0.5% aluminate, 2.5% oleic acid amide and 20% PBS calculated by weight percentage;

[0061] The preparation method is the same as in specific example 1.

Abstract

The invention relates to the technical field of plastic, and especially relates to a biodegradable plastic color master batch and a making method thereof. The biodegradable plastic color master batch comprises the following raw materials by weight percentages: 5-30% of pigment, 10-50% of filling material, 1-10% of plasticizer, 0.1-1% of coupling agent, 0.2-5% of lubricant and 20-80% of carrier. The biodegradable plastic color master batch has excellent physicochemical performance as common color master batch, and can avoid the disadvantages of time consuming and labor consuming for granulation and coloring of the biodegradable plastic color master batch and the influence to physical property; the biodegradable plastic color master batch can substitute the usage of the nondegradable plastic color master batch, and mixing of a nondegradable plastic component in the biodegradable plastic can be avoided.

Description

technical field [0001] The invention relates to the technical field of plastics, in particular to a fully biodegradable plastic color masterbatch and a preparation method thereof. Background technique [0002] With the continuous development of the plastics industry, the demand for plastics has also increased significantly. Because plastic is not easy to decompose and recycle, its waste also becomes harmful waste and pollutes the environment. Therefore, more and more scholars advocate the development and application of degradable plastics. [0003] Biodegradable plastics refer to a class of plastics that are degraded by the action of naturally occurring microorganisms such as bacteria, molds (fungi) and algae. The ideal biodegradable plastic is a polymer material that has excellent performance, can be completely decomposed by environmental microorganisms after being discarded, and is finally inorganicized to become an integral part of the carbon cycle in nature.
