Embodiment Construction

[0016] An environmentally friendly plastic bag, made of the following ingredients in parts by weight: modified plant starch 78, polylactic acid 14, nano-bentonite 6, soybean oil 1.2, tetrabutyl titanate 2.5, polyvinyl alcohol 35, glycerin 5, ethylene Triethoxysilane 1, carboxymethylcellulose polycyclic lactone 7, polyhydroxybutyrate valeric acid copolyester 5, nano titanium dioxide 0.3;

[0017] The particle size of the nano-bentonite is 18-20nm, and the nano-bentonite is pretreated: soak the nano-bentonite in a stearic acid solution with a mass of 3.85% for 30 minutes, heat to 86°C, filter, and dry the surface;

[0018] The modified vegetable starch is made of the following components in parts by weight: corn starch 25, tapioca starch 18, water chestnut starch 3, vinyl acetate 0.8, ammonium persulfate 0.1, octenyl succinic anhydride 0.3, aluminum sulfate 0.1, the The preparation method of the modified plant starch plant fiber is as follows: uniformly mix cornstarch, tapioca s...

Abstract

The invention discloses an environment-friendly plastic bag. The environment-friendly plastic bag is prepared from modified plant starch, polylactic acid, nano-bentonite, soybean oil, bagasse, tetrabutyl titanate, polyvinyl alcohol, glycerol, vinyltriethoxysilane, carboxymethylcellulose polycyclic lactone, polyhydroxybutyrate-hydroxyvalerate and nano-titania. According to the plastic bag easy to degrade, adopted corn starch, cassava starch and water chestnut starch are fast-growing and renewable resources which are abundant, low in unit cost and good in substitutability, and thus the plastic bag has significant economic benefits and ecological benefits; the plastic bag is excellent in biodegradability, and the mass can be reduced by 9-11% within 120 days after the plastic bag is buried. The longitudinal tensile strength of the plastic bag can reach 16.8 MPa, and the transverse tensile strength of the plastic bag can reach 15.6 MPa; the plastic bag easy to degrade is bright in color and luster, high in transparency, bearing capacity, water resistance and wet strength, and capable of meeting the requirements of customers for a larger capacity and reusability.

Description

technical field [0001] The invention relates to the field of plastics, in particular to an environmentally friendly plastic bag. Background technique [0002] Plastic bags have indeed brought convenience to our lives, but the convenience at this moment has brought long-term harm. The recycling value of plastic bags is low. In addition to causing "white pollution" during use, it also has potential hazards. The plastic structure is stable, it is not easy to be degraded by natural microorganisms, and it will not separate for a long time in the natural environment. This means that if waste plastic waste is not recycled, it will become pollutants in the environment and accumulate forever, which will cause great harm to the environment. As the concept of environmental protection is deeply rooted in the hearts of the people, more and more people continue to explore plastic bags with degradable and environmental protection functions. Contents of the invention [0003] The purpos...
