Embodiment Construction

[0015] Specific embodiments of the present invention will be described in detail below. In order to avoid too many unnecessary details, well-known structures or functions will not be described in detail in the following embodiments. Approximate language used in the following examples is for quantitative representations, indicating that certain variations in quantities are permissible without altering essential function. Unless defined otherwise, technical and scientific terms used in the following examples have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs.

[0016] A blown film containment method that isolates the POE in the middle layer.

[0017] Among them, the formula of the three-layer raw material is as follows:

[0018] Inner layer: A(LDPE):B(LLDPE)=3:7

[0019] Middle layer: A(LDPE):POE:B(LLDPE)=3:4:3

[0020] Outer layer: A(LDPE):B(LLDPE)=3:7.

[0021] Blown film temperature parameters are shown in Tab...

Abstract

The invention provides a film blowing containing method. According to the technical scheme, a POE ingredient is added into an interlayer, the temperatures of all regions of a film blowing machine barrel region are reduced by 10 DEG C, the phenomenon of gelatinization of the POE is avoided,thus, the effect of the POE is fully exerted, and precipitation of the POE is avoided. According to the film blowing containing method, the POE is effectively isolated on the interlayer, the POE cannot be precipitated, the high toughness of the POE can be fully exerted, the elongation at break of a product isincreased, and the loading capacity is improved It is shown through experimental verification that the mechanical performance of a prepared product is obviously superior to that of conventional products, the elongation at break is remarkably increased, and the loading capacity and the safety of use can be effectively improved. According to the film blowing containing method provided by the invention, the strength and the toughness of a bag are enhanced, the phenomenon of bag exploding is not generated in the using process, losses are reduced, the trouble generated when a client uses the bag is solved, and a better use effect is achieved.

Description

technical field [0001] The invention relates to the technical field of polymer materials, and further relates to the improvement of the film blowing method, in particular to a film blowing containment method. Background technique [0002] Blown film is a plastic processing method, which refers to a plastic processing technology that heats and melts plastic particles and then blows them into a film. Usually, the polymer is extruded into a tubular film blank, and it is passed through a high-pressure process under a good melt flow state. The air blows the tube film to the required thickness, and becomes a film after cooling and setting. [0003] POE (polyolefin elastomer) is a thermoplastic elastomer with narrow molecular weight distribution and uniform distribution of short chain branches. It has outstanding performance. By crosslinking POE, the heat resistance temperature of the material is increased and the permanent deformation is reduced. The main mechanical properties su...
