Problems solved by technology

However, during the processing of the extruder, the dispersion effect and plasticization effect of the biomass powder filler are not ideal, the comprehensive performance of the product needs to be further improved, and the processing cost is too high, which increases the product cost of the downstream blown film factory , thus affecting the popularization of fully biodegradable films

preparation example Construction

[0052] The second aspect of the present invention provides a method for preparing the biomass functional masterbatch as described above, comprising:

[0053] The biodegradable polymer and functional components are mixed and granulated at 80-180°C. When the functional component is biomass powder or inorganic filler, mix and granulate at 120-180°C; when the functional component is an auxiliary agent, mix and granulate at 80-120°C. Mixing and granulation can be carried out by means of extrusion, hot pressing or banburying, such as through a 65D or 75A extruder whose aspect ratio is 40:1, 56:1 or 60:1, preferably 56:1 or In hot-press granulation equipment, internal mixer, etc., biomass resin is prepared by extrusion or pressing at a certain processing temperature. Such as a variety of film materials, such as winding functional film, agricultural mulch film, plastic bag film, disposable glove film, etc., to meet various application requirements.

Abstract

The invention relates to the technical field of degradable materials, in particular to a biomass functional master batch as well as a preparation method and application thereof. The degradable material is prepared from the following raw materials in parts by weight: 40 to 70 parts of polyester resin, 10 to 30 parts of biomass resin and 5 to 35 parts of bio-based functional polymer. Under the combined action of the bio-based functional polymer provided by the invention, the polyester resin, the biomass resin and the like, the problem of molecular chain breakage of degradable macromolecules after two times of thermal history is avoided, the dispersion uniformity of biomass powder in a film is more effectively ensured, the excellent blow molding processability of a finished product is ensured, and material application cost is reduced while anti-puncture service performance and aging performance meeting the full service cycle of consumers are achieved. The problems that the characteristics of existing modified products are single and multifunctional film blowing products cannot be produced in a continuous production process are solved, and multifunctional film materials can be prepared according to the requirements of different films.

Description

technical field [0001] The present invention relates to the technical field of degradable materials, more specifically, the present invention relates to a biomass functional masterbatch and its preparation method and application. Background technique [0002] In recent years, the development of biodegradable plastics has been increasing day by day, and their applications have continued to expand. They have gradually replaced traditional plastics in the fields of packaging materials, disposable tableware, agricultural mulch and daily products. At present, in terms of performance and price, compared with traditional plastics, the performance of biodegradable plastics is too single, and the price is too expensive, which greatly limits the further development of biodegradable plastics. [0003] Among biodegradable polymer plastics, biomass powder, polylactic acid PLA, polycaprolactone PCL, poly β-hydroxyalkanoate PHA, etc. are currently used more. Polylactic acid is fermented by...
