Embodiment Construction
[0037] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0038] The application specifically discloses a degradable plastic masterbatch, wherein the content of PLA is 0.5%, the content of PBAT is 0.5% and the content of PVA is 0.5%.
[0039]Among them, those skilled in the art should know that PLA is the abbreviation of polylactic acid, also known as polylactide, which is a polyester polymer obtained by polymerization of lactic acid as the main raw material. PBAT is a thermoplastic biodegradable plastic, which is butylene adipate The copolymer with butylene terephthalate has the characteristics of both PBA and PBT. It not only has good ductility and elongation at break, but also has good heat resistance and impact properties; both have excellent The biodegradability of PLA and PBAT used in this embodiment are all related products of Dongguan Universe Environmental Protection Technology Co., Ltd. The modifier ...

The invention belongs to the technical field of degradable plastic master batches of ecological environment degradable materials and relates to a degradable plastic master batch and a preparation method thereof. The preparation method of the degradable plastic master batch comprises the following steps of: A, dehydrating PLA and PBAT by adopting a particle dehydrator, and drying the surfaces of the PLA and the PBAT by virtue of a dryer; B, putting the PLA and the PBAT in the step A,and a modifier into a closed high-speed stirrer for mixing the PLA, the PBAT and the modifier, in the mixing process, controlling the temperature to be 60 DEG C and the mixing time to be 10-20 minutes, and obtaining a main material; and C, adjusting the parameters of a weightless feeder according to proportions, adding the main material in the step B and auxiliaries into a screw extruder at the same time in proportion for melt blending with mulling temperature being 140-170 DEG C, extruding the melted materials through a screw extruder and conveying the melted materials to a granulator for granulation, and the content of the PLA in the prepared color master batch being 1%, the content of the PBAT being 1%, the content of PVA being 1%. The method has the advantages of high mixing efficiency, low production cost and the like.
Description
technical field [0001] The invention relates to the technical field of degradable plastic masterbatches of ecological environment degradable materials, in particular to a degradable plastic masterbatch and a preparation method thereof. Background technique [0002] Plastic masterbatch is a concentrate made by adding a super-normal amount of plastic additives to the resin; when manufacturing plastic products, it is not necessary to add this kind of plastic additives, but only need to add the corresponding masterbatch. Therefore, it is one of the most important forms of application of plastic additives in the world today. Polymer materials have good functionality and practicability, and play a huge role in social construction and people's daily life. However, in the production and application of traditional polymer materials, the amount of color masterbatch added to the resin is generally 2-5%. In the calculated matrix resin, the content of the carrier resin accounts for at l...
