Acetyl Octapeptide-3 can be used as a chemoattractant chemoattractant for the preparation of environmentally friendly degradation additives for polymers, such as a dual-degradation additive that promotes photo-oxidative degradation and biodegradation of polymers. It is a concentrated plastic masterbatch in appearance The new environment-friendly dual-degradable additive, the masterbatch and the polymer are made into a composite material through molding and processing at a ratio of 0.1-5.0%: 95.0-99.9% by weight, so that this composite material not only It can not only undergo photooxidative degradation but also biodegradation, and can also repair soil and compost. In addition, it can also block oxygen and flame retardancy in many applications; this environmentally friendly dual-degradable masterbatch can be applied to many kind of polymer. The technical scheme adopted to achieve the above purpose is: the proportioning of each component by weight percentage is as follows: 30-50% of resin used as carrier; 26-40% of composite photooxidative degradation accelerator; photooxidative degradation induction period regulator 1‑5%; carboxylic acid or its derivatives 1‑5%; microcapsule composite 15‑25%. On the basis of the above technical solution, the microcapsule composite material includes: an outer wall material accounting for 10-30% of the total weight of the microcapsule composite material; an inner layer of multi-core core material accounting for 70-30% of the total weight of the microcapsule composite material 90%; the inner multi-core core material includes: polymer composite microspheres, accounting for 70-90% of the total weight of the inner multi-core core material; biosurfactant, accounting for 5-15% of the total weight of the inner multi-core core material ; Biodegradation induction period regulator, accounting for 5-15% of the total weight of the inner multi-core core material; the polymer composite microspheres include: microsphere wall material, accounting for 10-30% of the total weight of the polymer composite microspheres; The microsphere multi-core core material accounts for 70-90% of the total weight of the polymer composite microsphere; the microsphere multi-core core material includes: a chemical attractant chemotaxis agent accounts for 50-60% of the total weight of the microsphere multi-core core material; microorganisms , accounting for 35-40% of the total weight of the microsphere multi-core core material; microbial protection agent, accounting for 5-10% of the total weight of the microsphere multi-core core material.
On the basis of the above technical solution, the outer wall material is at least one of the following substances: gum arabic, sodium alginate, propylene glycol alginate, carboxymethyl alginate, polyvinyl alcohol, methyl cellulose cellulose, methyl cellulose, ethyl cellulose, polyvinylpyrrolidone and polymethyl methacrylate; when two or more of the above substances are used at the same time, the ratio shall be based on the principle of uniform distribution; the biosurfactant is laurel At least one of sodium acyl glutamate or surfactin; when the two are used at the same time, each accounts for 50% of the proportion; the CAS number of the surfactin is 24730-31-2; the biodegradation induction period The regulator is at least one of the following substances: 2(3H)furanone, 2(5H)furanone, 2,5-dimethyl-4-hydroxy-3(2H)-furanone, 3,5-di Methylpentenyldihydro-2(3H), 3-(3,4-difluorophenyl)-4-(4-m(methylsulfonyl)phenyl)-2-(5H)furanone, triphenyl Base-4-(4-(methylsulfonyl)phenyl)-2-(5H)furanone, 5,5-dimethyl-4-(4-(methylsulfonyl)phenyl)-3-(3 -Fluorophenyl)-5(H) furanone; when using two or more of the above-mentioned substances at the same time, the proportioning is arbitrary; the microsphere wall material of the polymer composite microsphere is at least one of the following substances: Maltodextrin, γ-cyclodextrin, β-cyclodextrin, carboxymethyl-β-cyclodextrin, hydroxymethylcellulose, polyvinylpyrrolidone; when two or more of the above substances are used at the same time, the proportion According to the principle of uniform distribution; the chemical attractant chemotactic agent is at least one of the following substances: furanoylboronic acid diester, 3-hydroxyl-4, 5-dimethyl-2 (5H) furanone, 5-ethyl ‑3‑hydroxy‑4‑methyl‑2(5H)‑furanone, L‑2‑amino‑4‑hydroxybutyric acid, acetyl homoserine lactone, 3-oxododecanoyl homoserine lactone, N-acyl homoserine lactone, 2-heptyl-3-hydroxy-4-quinolone, acetyl octapeptide-1, or palmitoyl oligopeptide. Acetyl Octapeptide-3 can be used as a chemoattractant chemoattractant in the above-mentioned dual degradation additives.
