Abstract

The invention discloses a tough degradable artistic visor and a forming method thereof. The tough degradable artistic visor is prepared from the following components in parts by weight: 5 to 10 parts of poly-L-lactic acid, 10 to 30 parts of butylene adipate / butylene terephthalate copolymer, 0.015 to 0.3 part of stereopolylactic acid fiber, 1.5 to 5 parts of processing aid and 0.3 to 3 parts of ornament. The invention relates to the technical field of hat decoration materials, in particular to a tough degradable artistic visor and a forming method thereof, the visor can effectively replace a traditional PP plastic visor, and environmental pollution can be effectively reduced.

Description

technical field [0001] The invention relates to the technical field of hat decoration materials, in particular to a strong and degradable artistic visor and a forming method thereof. Background technique [0002] At present, the visor is mainly made of polypropylene material, which is widely used because of its light weight, excellent mechanical properties, and low hardness, which can be used for sewing processing. However, polypropylene plastic, like other plastics, is difficult to degrade under natural conditions, and it is difficult to meet the needs of sustainable development and environmental protection. With the vigorous promotion of the plastic ban in recent years, it is an inevitable choice for the future development of the field of hats to seek degradable visor substitutes. [0003] Application No. 200520063814.6 discloses a hat with a straw weaving effect. Straw weaving ornaments are sewn on the cap body and visor, which makes the hat have original and natural sen...
