AI Technical Summary

Benefits of technology

This patented technical effect lies within this new type of material that allows for easy production with various sizes without requiring expensive equipment or sacrificial resources during manufacturing process. It also provides excellent properties such as flexibility when injected into product formulations like food containers while maintaining their strength over time.

Problems solved by technology

This patented technical problem addressed by this patents relates to improving the use of reusable or recycled plastic containers such as those made up mostly of polyethylene terephthalate (PET) resin, while reducing its impact on nature through landfill management practice. Additionally, finding ways to reduce the volume occupied by discarded plastic container lids can help prevent damage caused by excessive packaging material usage.

Embodiment 1

[0014] The weight percentage is: 5% PBS; 40% PLA; 10% PHB; 42% inorganic powder; 2% plasticizer; Stir in a high-speed mixer for 15 minutes to mix evenly, and then inject plastic bottle caps 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

[0016] The weight percentages are: 15% PBS; 35% PLA; 10% PHB; 37% inorganic powder; 1% plasticizer; 2% compatibilizing modifier. Stir in a high-speed mixer for 10 minutes to make the mixture uniform, and then inject plastic bottle caps 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

[0018] The weight percentage is: 20% PBS; 25% PLA; 10% PHB; 40% inorganic powder; 4% plasticizer; Stir in a high-speed mixer for 20 minutes to make the mixture uniform, and then inject plastic bottle caps 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 bottle cap and a preparation method. The bottle cap comprises the following components in percent by weight: 5-30% of PBS (polybutylene succinate), 5-50% of PLA (polylactic acid), 0-20% of PHB (poly 3-hydroxybutyrate), 0-50% of an inorganic powder, 1-10% of a plasticizer, and 0-5% of a compatibilizing modifier. The preparation method is simple and flexible; the obtained material can be formed by the injection molding processing technology; the material can be made into plastic bottle caps of various specifications; the material has low cost, excellent performance, and broad development spaces; and the material can be recycled, can be biodegradable after being discarded, and meets environmental protection needs.
