Embodiment 1

[0013] The weight percentage is: 5% PBS; 40% PLA; 10% PBST; 42% inorganic powder; 2% plasticizer; 1% compatibilizer modifier. Stir in a high-speed mixer for 15 minutes to make the mixing uniform, and then inject the motor shaft sleeve on the injection molding machine. The injection temperature is controlled at 200°C in the first zone; 190°C in the second zone; and 180°C in the third zone.

Embodiment 2

[0015] The weight percentages are: 15% PBS; 35% PLA; 10% PBST; 37% inorganic powder; 1% plasticizer; 2% compatibilizer modifier. Stir in a high-speed mixer for 10 minutes to make the mixing uniform, and then inject the motor shaft sleeve on the injection molding machine. The injection temperature is controlled at 210°C in the first zone; 200°C in the second zone; and 190°C in the third zone.

Embodiment 3

[0017] The weight percentages are: 20% PBS; 25% PLA; 10% PBST; 40% inorganic powder; 4% plasticizer; 1% compatibilizer modifier. Stir in a high-speed mixer for 20 minutes to make the mixing uniform, and then inject the motor shaft sleeve on the injection molding machine. The injection temperature is controlled at 220°C in the first zone; 210°C in the second zone; and 200°C in the third zone.

Abstract

The invention relates to a biodegradable plastic motor shaft sleeve and a preparation method thereof. The biodegradable plastic motor shaft sleeve comprises the following components in percentage by weight: 5-30% of PBS(poly (butylene succinate)), 5-50% of PLA (polylactic acid), 0-20% of PBST (poly (butylene succinate) / butylene terephthalate), 0-50% of inorganic powder, 1-10% of plasticizer and 0-5% of compatibilization modifier. The preparation method of the invention is simple and flexible. The prepared material can be formed by injection machining processes, and can be prepared into motor shaft sleeves of various specifications. The material has low cost, excellent performance and wide development space, can be recycled and can be biologically degraded after being discarded, thereby meeting the requirement of environmental protection.

Description

Technical field [0001] The invention relates to a plastic motor shaft sleeve and a preparation method, in particular to a biodegradable plastic motor shaft sleeve and a preparation method. Background technique [0002] In the past few decades, the development of the plastics industry has been mainly based on petroleum-based synthetic resins. But oil is a kind of resource with limited resources and non-renewable resources. The price increase in recent years has brought a big impact on the plastics industry. At present, it has become an irresistible trend to study and formulate reduction, re-resource, and implement the use of renewable resources to supplement and replace petroleum resources to ensure the sustainable development of the plastics industry. At the same time, because plastic waste is difficult to degrade naturally in the environment, especially disposable plastic product waste is lightweight, large in quantity, scattered, and messy, it is difficult to collect, and the ...
