PLA heat-resistant knife, fork and spoon and production method

A PLA material used by a PLA heat-resistant knife, fork and spoon of the invention comprises the following components in parts by weight: 40-80 parts of racemic polylactic acid; 10-30 parts of aliphatic polyester; 0.5-1 part of a nucleating agent; 5-30 parts of an inorganic filler; 0.3-3 parts of a dispersant; and 0.3-1 part of an antioxidant. The PLA heat-resistant knife, fork and spoon has effectively improved heat resistance, meets the high-temperature use requirement, can be stably formed, and is beneficial to efficient processing and production. 本发明的一种PLA耐热刀叉勺，其所使用的PLA材料，包括如下重量份的组分：外消旋聚乳酸40份～80份；脂肪族聚酯10份～30份；成核剂0.5份～1份；无机填料5份～30份；分散剂0.3份～3份；抗氧剂0.3份～1份。该PLA耐热刀叉勺能有效提高耐热性，满足高温使用要求，还能够稳定成型，有利于高效加工生产。
