Embodiment 1

[0030] A degradable lunch box, made of the following raw materials in parts by weight: 45 parts of poly-β-hydroxybutyrate, 25 parts of modified polybutylene succinate, 25 parts of composite biochar, lignocellulose Airgel 15 parts, polylactic acid 15 parts, modified hydroxypropyl acetylated corn starch 8 parts, aluminate coupling agent 6 parts.

[0031] The preparation method of described modified polybutylene succinate is:

[0032] S1. Mix acetate starch and dimethyl sulfoxide with ethanol in a mass ratio of 1:0.3, and react with stirring at 60°C for 2 hours, then let stand for 24 hours to obtain modified acetate starch, the dimethyl sulfoxide Sulfone accounts for the mass of the mixed system;

[0033] S2. Add polybutylene succinate to the above-mentioned modified acetate starch, stir and react at 80°C for 3 hours to make modified polybutylene succinate; wherein, the modified acetate starch, polybutylene succinate The mass ratio of butanediol diacid is 1:2.

[0034] The pre...

Embodiment 2

[0040] This embodiment provides a degradable lunch box. Compared with Embodiment 1, the difference is that it is made of the following raw materials in parts by weight: 40 parts of poly-β-hydroxybutyrate, modified polysuccinic acid 30 parts of butanediol ester, 20 parts of composite biochar, 20 parts of lignocellulose airgel, 20 parts of polylactic acid, 5 parts of modified hydroxypropyl acetylated corn starch, and 5 parts of aluminate coupling agent.

Embodiment 3

[0042] This embodiment provides a degradable lunch box. Compared with Embodiment 1, the difference is that it is made of the following raw materials in parts by weight: 50 parts of poly-β-hydroxybutyrate, modified polysuccinic acid 20 parts of butylene glycol ester, 30 parts of composite biochar, 10 parts of lignocellulose airgel, 10 parts of polylactic acid, 10 parts of modified hydroxypropyl acetylated corn starch, and 8 parts of aluminate coupling agent.

Abstract

The invention discloses a degradable lunch box, which is made of the following raw materials in parts by weight: 40-50 parts of poly-β-hydroxybutyrate, 20-30 parts of modified polybutylene succinate, compound 20-30 parts of biochar, 10-20 parts of lignocellulose airgel, 10-20 parts of polylactic acid, 5-10 parts of modified hydroxypropyl acetylated cornstarch, 5-8 parts of coupling agent; the present invention can The production cost of the degradable lunch box is low, the overall strength is good, the temperature resistance is good, and it can be degraded quickly in the natural environment.

Description

technical field [0001] The invention relates to a disposable tableware, in particular to a degradable lunch box. Background technique [0002] Disposable fast food boxes have changed from foam lunch boxes to environmentally friendly lunch boxes. The original foam lunch boxes have been eliminated because they are not resistant to high temperatures and the production process has caused damage to the environment. Plastic lunch boxes, paper lunch boxes, wooden lunch boxes, etc. Among them, plastic has become the mainstream material for manufacturing disposable fast food boxes due to its low toxicity, high melting point, strong plasticity, easy production and relatively low cost; disposable lunch boxes made of plastic are mainly There are two kinds of PP polypropylene and PS polystyrene, both of which are non-toxic, tasteless and odorless, and PP is relatively soft. Generally, the use temperature of PP is -6 degrees to +120 degrees, so it is especially suitable for hot meals and ...
