Embodiment 1

[0036] Mix 100Kg of copolyester 1, 0.30Kg of antioxidant 168, 15Kg of silicon dioxide, 1.5Kg of UV-531, 0.5Kg of lubricant EBS, and 5Kg of MBS in a high-mixer, and then pass it through a film blowing machine. Blowing to obtain a biodegradable shopping bag 1 . The light transmittance and flexibility are good. According to the technical standard of GB / T21661-2008 plastic shopping bags', the test results are as follows: Lifting test: 3 bags have no rupture, drop test: 3 bags have no rupture and water leakage: The three bags are watertight, with a nominal load-bearing capacity of 8.5kg and a sealing strength of 14.6N / 15mm.

[0037] Determination of final aerobic biodegradation and disintegration capacity of materials under controlled composting conditions according to GB / T19277.1-2011. The polymers were tested for percent biodegradation using the test method for the method of measuring released carbon dioxide. The test results are as follows:

[0038]

Embodiment 2

[0040] Adopt the montmorillonite of 15Kg to replace silicon dioxide, other is the same as embodiment 1. As a result, it was found that the mechanical properties and biodegradability were basically the same as in Example 1.

Embodiment 3

[0042] Adopt the wollastonite of 15Kg to replace silicon dioxide, other is the same as embodiment 1. As a result, it was found that the mechanical properties and biodegradability were basically the same as in Example 1.

Abstract

The invention discloses a polyester biodegradable shopping bag, which is used for supermarket shopping and is prepared by chain extension and modification of diacid and dihydric alcohol copolyester of diacid fatty group of introduced aromatic group, and the polyester biodegradable shopping bag has the advantages of excellent performance, high molecular weight, high branching degree, high crystallization degree, less and nontoxic impurity content, and biodegradable performance.

Description

technical field [0001] The invention relates to a polymer, in particular to a polyester biodegradable shopping bag and its preparation and application. Background technique [0002] Shopping bags provide great convenience to people in daily life, and are essential items for people to go shopping. The shopping bags currently available on the market mainly include: plastic shopping bags, non-woven shopping bags, paper shopping bags, cotton and linen shopping bags, etc. Plastic shopping bags include ordinary plastic shopping bags, starch-based plastic shopping bags and degradable plastic shopping bags. Among them, ordinary plastic shopping bags are difficult to degrade. Starch-based plastic shopping bags rely on food, so the prospects are not good. The country has been widely promoted, but its high cost makes it difficult to promote it on a large scale in the country in a short period of time. Non-woven shopping bags are non-woven fabrics made of plastics such as polypropylen...
