Abstract

The invention discloses a flexible tear-resistant hydrophobic garbage bag which consists of the following raw materials in parts by weight: 2-3 parts of citric acid, 100-140 parts of polypropylene, 6-10 parts of carbon nano tube, 0.4-1 part of zinc acetylacetone, 2-3 parts of sucrose acetate isobutyrate, 1-2 parts of sodium myrastate, 10-12 parts of aluminium isopropoxide, 10-13 parts of acetyl tributyl citrate, 0.8-1 part of calcium ricinoleate, 1.8-2 parts of glycolic acid, 0.01-0.02 part of cerium oxide, 1-3 parts of polylactic acid, 1-2 parts of trifluoroethyl methacrylate, 2-4 parts of ammonium zirconium carbonate, 0.6-2 parts of sulfur, 1-2 parts of phytosterol, 6-8 parts of polyvinylpyrrolidone, 2-4 parts of polyethyleneimine, 0.1-0.3 part of dimethicone, 0.1-0.2 part of tetrabutylammonium bromide and 0.7-1 part of ammonium sulfate alkylphenol ethoxylate. The garbage bag disclosed by the invention can be recycled and has high water resistance, wiping resistance and tear resistance; the added polymer aluminum sol can effectively improve the dispersity of the carbon nano tube in polypropylene; and the flexibility of the product film can be effectively improved.

Description

technical field [0001] The invention mainly relates to the field of garbage bags, in particular to a flexible and tear-resistant hydrophobic garbage bag and a preparation method thereof. Background technique [0002] Most of the plastic bags that people use for daily shopping are made of petroleum. Due to the huge amount of use, the waste of resources and environmental pollution are very alarming. It takes about 200 years for plastic bags to rot in the ground and seriously pollute the soil; if they are incinerated, they will produce harmful smoke and toxic gases, which will pollute the environment for a long time. [0003] China uses 1 billion plastic bags to buy food every day, and the consumption of other kinds of plastic bags is more than 2 billion per day. Beijing discards 2.3 billion plastic bags every year, generating 140,000 tons of waste plastic packaging waste, accounting for 3% of the entire domestic waste. Shanghai produces 190,000 tons of waste plastic packagin...
