Embodiment 1

[0013] The weight percentage is: 5% PBS; 40% PLA; 10% PBST; 42% inorganic powder; 2% plasticizer; Stir in a high-speed mixer for 15 minutes to make the mixture uniform, and then inject into a motor shaft sleeve on an injection molding machine. The injection molding 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% compatibilizing modifier. Stir in a high-speed mixer for 10 minutes to make the mixture even, and then inject it into a motor shaft sleeve on an injection molding machine. The injection molding 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 percentage is: 20% PBS; 25% PLA; 10% PBST; 40% inorganic powder; 4% plasticizer; Stir in a high-speed mixer for 20 minutes to make the mixture uniform, and then inject into a motor shaft sleeve on an injection molding machine. The injection molding 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, 5-50% of PLA, 0-20% of PBST, 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, can be prepared into motor shaft sleeves of various specifications, 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] Over the past few decades, the development of the plastics industry has been largely based on petroleum-based synthetic resins. However, petroleum is a kind of limited and non-renewable resource, and its price has risen in recent years, which has brought great impact to the plastics industry. At present, it has become an irresistible trend to study and formulate reduction, recycling and implementation of petroleum resource supplementation and substitution strategies using renewable 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 the waste of disposable plastic products is light, large, scattered, messy, and difficult to collect. ...
