Technical Field
The invention belongs to the field of self-sealing bag preparation, and particularly relates to a fully-degradable self-sealing bag with high repeated use rate.
Background
Self-sealing bags are widely used in life due to the characteristic of the repeatable sealing, but PE base materials are still widely used in the market at present, but PE is not degraded, and a plurality of problems are brought about in the aspect of environmental pollution. Thus, studies have been made on the preparation of biodegradable self-sealing bags using biodegradable substrates such as PLA, PBAT, etc.
The biodegradable self-sealing bags are used in the current market, but the problem of poor repeated opening and closing tightness generally exists, so that liquid or articles leak, and the use experience of consumers is seriously affected. The self-sealing bag is prepared by using PLA and PBAT to prepare the self-sealing strip and then adhering the self-sealing strip to the inner side of the film bag in the patent CN 109627703A, but the self-sealing bag is certainly increased in production procedures and the production cost is increased. The biodegradable self-sealing bag is prepared by one-time molding through the film blowing process, and on the premise of ensuring that the self-sealing bag has good sealing performance, the biodegradable self-sealing bag solves the degradation problem, protects the environment and saves manpower and material resources.

Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to fall within the scope of the invention.
Comparative example 1
Step one: weighing 5kg of PLA, 84.5kg of PBAT, 10kg of PPC, 1kg of chain extender ADR4370F, 0.3kg of erucamide and 0.2kg of antioxidant;
step two: the weighed raw materials are sent into a high-speed mixer to be mixed uniformly, then sent into a double-screw extruder to be granulated, the temperature of the double-screw extruder is 150-190 ℃, and air cooling granulation is carried out to obtain material particles;
step three: and (3) the material particles are blown by a three-layer co-extrusion film blowing machine, wherein the film blowing temperature is 160-185 ℃, the blowing ratio is 2.5-4, the film thickness is 0.06mm, and the fully-degradable self-sealing bag with high repeated use rate is obtained.
Example 1
Step one: weighing 5kg of PLA, 56.5kg of PBAT, 10kg of PPC, 2525 kg of Vack auxiliary agent, 25kg of smooth stone powder, 1kg of chain extender ADR4370F, 0.3kg of erucamide and 0.2kg of antioxidant;
step two: the weighed raw materials are sent into a high-speed mixer to be mixed uniformly, then sent into a double-screw extruder to be granulated, the temperature of the double-screw extruder is 150-190 ℃, and air cooling granulation is carried out to obtain material particles;
step three: and (3) the material particles are blown by a three-layer co-extrusion film blowing machine, wherein the film blowing temperature is 160-185 ℃, the blowing ratio is 3-4, the film thickness is 0.06mm, and the fully-degradable self-sealing bag with high repeated use rate is obtained.
The self-sealing bags prepared in examples 1-2 were tested for melt index properties and the results are shown below.
The seal test was performed according to BBT0014-2011, and the experimental picture is shown in FIG. 5.
As can be seen from fig. 1 to 5, in the melt index test comparison of comparative example 1 and example 1, the use of the compound of the wack auxiliary agent and the chain extender significantly reduces the melt index, and the addition of the inorganic filler improves the tensile strength without affecting the elongation. Compared with PE self-sealing bags used in the current market, the PE self-sealing bag has higher heat sealing strength, so that the sealing performance of the product is ensured. As can be seen from comparing fig. 2 and fig. 3, the present patent performs formulation optimization, and example 1 significantly improves the formability of the self-sealing bag female teeth compared with comparative example 1, and the good wedging degree of the female teeth ensures the sealing performance of the product. Since the comparative example 1 had a small tooth forming difference, which resulted in failure to complete the sealing test of the standard BBT0014-2011, the present test performed a sealing test on example 1 and PE self-sealing bags. The test result shows that the sealing of the degradation self-sealing bag is equivalent to that of the PE self-sealing bag, and no water leakage occurs. The good formability and strength of the primary and secondary teeth in example 1 enable the primary and secondary teeth to have good dimensional stability and sealing performance after the self-sealing bag is unsealed for many times, and ensure high reuse rate.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present invention, and are not limited thereto; although the invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit and scope of the technical solutions of the embodiments of the present invention.
