Embodiment 1

[0023] Weigh each component so that the percentage composition of each component is respectively: P3HB4HB (4HB molar content is 6%) 76%, P3HB4HB (4HB molar content 12%) 10%, talcum powder (1250 orders) 5%, weight Crystal powder (3000 mesh) 5%, γ-aminopropyltriethoxysilane 0.1%, titanium dioxide (anatase) 0.5%, β(3,5-di-tert-butyl-4-hydroxyphenyl) propionic acid Pentaerythritol ester 0.1%, dioctadecyl pentaerythritol diphosphite 0.2%, barium stearate 0.3%, zinc stearate 0.2%, paraffin 0.2%, erucamide 0.4%, glyceride 2%.

[0024] In the above formula, the talc powder and barite powder are first treated with γ-aminopropyltriethoxysilane, and then mixed with other materials for plasticizing, extruding and granulating.

Embodiment 2

[0026] Weigh each component so that the percentages of each component are: P3HB4HB (4HB molar content 10%) 51%, muscovite (1250 mesh) 12%, barite powder (3000 mesh) 5%, PLA 30% , Titanium Dioxide (Anatase) 0.5%, γ-Aminopropyl Triethoxysilane 0.2%, β(3,5-Di-tert-butyl-4-hydroxyphenyl) Pentaerythritol Propionate 0.1%, Dioctadecyl Alkyl alcohol pentaerythritol diphosphite 0.2%, barium stearate 0.3%, zinc stearate 0.2%, paraffin 0.2%, erucamide 0.3%.

Embodiment 3

[0028] Weigh each component so that the percentage composition of each component is respectively: PHBV (HV molar content 10%) 77%, P3HB4HB (4HB12%) 10%, silicon dioxide (6000 orders) 10%, titanium dioxide (sharp Titanium) 0.5%, γ-aminopropyltriethoxysilane 0.1%, β(3,5-di-tert-butyl-4-hydroxyphenyl) pentaerythritol propionate 0.1%, dioctadecyl alcohol pentaerythritol di Phosphite 0.2%, calcium stearate 0.3%, zinc stearate 0.2%, paraffin wax 0.2%, oxidized polyethylene wax 0.4%, epoxy soybean oil 1%.

Abstract

The invention discloses a completely biodegradable material for cards, which comprises the following components by weight: polyhydroxyalkanoate is 50% to 99%, modifier is 0% to 50%, and filler is 0% to 40%. , Other additives are 0-10.5%. The present invention modifies the polyhydroxyalkanoate by adding suitable modifying agents and other auxiliary agents, so as to improve the performance of the polyhydroxyalkanoate, so as to meet the performance requirements of the card and make it It can be processed and produced with traditional equipment.

Description

technical field [0001] The invention belongs to the field of materials, in particular to a completely biodegradable material for cards. Background technique [0002] With the rapid development of the economy, the problem of the disposal of many industrial wastes is becoming more and more serious, which not only increases the burden on the earth, but also pollutes and harms the natural environment very seriously. With the development of finance and urbanization, cards have become an indispensable thing in people's lives. As the number of cards issued increases gradually, more and more cards are discarded. [0003] Cards currently on the market, such as bank cards, mobile phone cards, and various other IC cards, are mainly made of traditional plastics, such as PET (polyethylene terephthalate), PVC (polyvinyl chloride), PP ( Polypropylene), PS (polystyrene) and other petroleum-based materials are non-degradable and not easy to recycle and reuse. If they are not recycled in tim...
