Low-cost toughened plastic bag material and preparation method thereof

Abstract

The invention discloses a low-cost toughened plastic bag material which is prepared from the following raw materials in parts by weight: 20-30 parts of biomass fiber, 2-4 parts of trichloroisocyanuricacid, 26-30 parts of polyvinyl alcohol, 1-2 parts of alkylolamide, 5-7 parts of palm wax, 0.4-1 part of 8-hydroxyquinoline, 130-150 parts of ethylene-vinyl acetate copolymer, 2-4 parts of zinc hydroxystannate, 1-2 parts of ammonium ethoxylated alkyl sulfate, 8-10 parts of nano calcium carbonate, 3-5 parts of hydroxyethyl acrylate and 0.7-1 part of trimethylolpropane, wherein the stability of a finished product of the plastic bag material is effectively improved. According to the plastic bag material, by adopting sisal fiber as a biomass raw material, the production cost is effectively reduced; meanwhile, the flexibility of the finished product of plastic bag is improved, and the tearing strength is enhanced.

Description

technical field [0001] The invention belongs to the field of plastic bags, and in particular relates to a low-cost toughened plastic bag material and a preparation method thereof. Background technique [0002] Commonly used food plastic bags are mostly made of polyethylene film, which is non-toxic, so it can be used to hold food. There is also a kind of film made of polyvinyl chloride, polyvinyl chloride itself is non-toxic, but the additives added according to the purposes of the film are often harmful substances to the human body and have certain toxicity. Therefore, this type of film and plastic bags made of this film are not suitable for containing food; however, polyethylene and polyvinyl chloride have low tensile strength, and the thinner plastic film obtained by tape casting has poor mechanical properties and is easy to damage; [0003] At present, ordinary plastics are mostly made of petrochemical raw materials. The expansion application of plastics has led to the r...

Problems solved by technology

There is also a film made of polyvinyl chloride, polyvinyl chloride itself is non-toxic, but the additives added according to the use of the film are often harmful substances to the human body and have certain toxicity

Therefore, this type of film and plastic bags made of this film are not suitable for containing food; however, polyethylene and polyvinyl chloride have low tensile strength, and the thinner plastic film obtained by tape casting has poor mechanical properties and is easy to damage;

[0003] At present, ordinary plastics are mostly made of petrochemical raw materials. The expansion application of plastics has led to the rapid exploitation of petroleum and the use of them to produce plastics. The non-renewable resources and unsustainable development of energy will soon lead to an "energy crisis";
