A degradable environmental protection garbage bag and its production method

Abstract

The invention discloses a degradable environmental protection garbage bag, which is characterized in that it is made of the following raw materials in parts by weight: 40-50 parts of polycarboxy-terminated polylactic acid hydrogenated benzoin ester, 35-45 parts of polyurethane-based polyester urea resin, 1-3 parts of filler, 0.2-0.5 parts of coupling agent, 0.5-1.5 parts of compatibilizer, 0.3-1 part of heat stabilizer, 3-5 parts of hydroxyl-terminated hyperbranched polyester. The invention also provides a manufacturing method of the degradable environmental protection garbage bag. The degradable environmental protection garbage bag disclosed by the invention has good mechanical properties, good performance stability, strong durability, good degradable performance after being discarded, high degradation efficiency, and excellent toughness and waterproof performance.

Description

technical field

[0001] The invention relates to the technical field of garbage bags, in particular to a degradable environmental protection garbage bag and a manufacturing method thereof. Background technique

[0002] Garbage bag is an important plastic product in people's daily life. It has a very wide range of uses in the fields of household garbage collection, transportation, and sanitation cleaning. It brings great convenience to thousands of households and provides an important contribution to environmental protection. Safeguards and even facilitates garbage sorting.
