The invention aims to provide a biodegradable blown film which has puncture energy of more than 22J/mm and high puncture resistance strength, so that the carrying capacity of the film is improved.
In order to achieve the purpose, the brightening agent adopts the following technical scheme: the biodegradable blown film is obtained by stirring the following components in parts by weight by a high-speed mixer and then blowing by a film blowing machine:
100 parts of polybutylene sebacate terephthalate,
30-60 parts of tetramethyl adipate-terephthalate copolyester,
25-50 parts of polylactic acid,
3-8 parts of epoxidized soybean oil,
2-5 parts of 4-hydroxybutyl acrylate glycidyl ether,
1-3 parts of dodecenyl succinic anhydride,
0.5-2 parts of ethylene bis-stearamide,
1-3 parts of lauric acid monoglyceride,
0.5-1.5 parts of antioxidant,
0.3-1 part of a release agent,
3-6 parts of filler.
The technical scheme further improved in the technical scheme is as follows:
1. in the above scheme, the antioxidant is at least one of antioxidant 1010, antioxidant 1076, antioxidant 2246 and antioxidant 168.
2. In the above scheme, the filler is an inorganic filler or an organic filler.
3. In the scheme, the inorganic filler is talcum powder, pearl powder, aluminum oxide, shell powder, calcium carbonate or barium sulfate.
4. In the above scheme, the organic filler is natural starch, straw, natural fiber or chitosan.
5. In the above scheme, the release agent is silicone master batch or a montan wax.
Due to the application of the technical scheme, compared with the prior art, the invention has the following advantages:
the biodegradable blown film realizes that the biodegradation rate after 12 weeks exceeds 90%, and simultaneously, based on 100 parts of polybutylene sebacate, 30-60 parts of tetramethyl adipate-terephthalate copolyester, 2-5 parts of 4-hydroxybutyl acrylate glycidyl ether and 1-3 parts of dodecenyl succinic anhydride are further added, the puncture energy is larger than 22J/mm, and the puncture resistance strength is high, so that the carrying capacity of the film is improved.
