preparation example Construction

[0036] Correspondingly, the embodiment of the present invention provides a method for preparing a fully biodegradable balloon base as described above, including the following steps:

[0037] According to parts by mass, blend polylactic acid, toughening agent, filler, lubricant and compatibilizer to obtain a material;

[0038] The material is passed through extrusion and injection molding processes to obtain a fully biodegradable balloon base.

[0039] In the embodiment of the present invention, raw material components such as polylactic acid, toughening agent, filler, etc. are put into a blender in proportion to mix to obtain materials; the content of each component's dosage ratio, type selection, etc. are as described above.

[0040] In the embodiment of the present invention, the obtained material is put into a twin-screw extruder for melt extrusion, granulated to obtain a special material, and the temperature of extrusion melting may be 160-200°C.

[0041] In the embodiment of the pr...

Embodiment 1

[0049] According to the mass ratio of 80 parts of PLA, 18 parts of PBAT, 1 part of EBS, 0.5 part of KH550, 0.5 part of talc (particle size greater than 100 mesh), the raw material components are put into the mixer for blending to obtain the material; Said material is put into the twin-screw extruder to enter into the melt extrusion, granulated to obtain the special material, the extrusion melting temperature is 160-200℃;

[0050] Then, put the special material into the injection molding machine for melt injection molding, the injection temperature is 160-200℃, and the finished balloon bottom support is prepared, the structure is as figure 1 Midsole support 1.

[0051] In addition, the special material is made into a standard sample, and the performance test is performed. The result is: the tensile strength is 35 MPa, and the elongation at break is 168%.

Embodiment 2

[0053] According to the mass ratio of 75 parts of PLA, 10 parts of PCL, 12.5 parts of calcium carbonate (particle size greater than 100 mesh), 2 parts of EBS, and 0.5 parts of KH550, the raw material components are put into the mixer for blending to obtain materials; Said material is put into the twin-screw extruder to enter into the melt extrusion, granulated to obtain the special material, the extrusion melting temperature is 160-200℃;

[0054] Then, put the special material into the injection molding machine for melt injection molding, and the injection temperature is 160-200°C to prepare the finished balloon bottom support. The structure is as figure 1 Midsole support 1.

[0055] In addition, the special material was made into a standard sample, and the performance test was performed. The result was that the tensile strength was 29 MPa and the elongation at break was 93%.

Abstract

The invention provides a full-biodegradable balloon bottom support and a preparation method. The bottom support is prepared through extrusion and injection molding from the following materials: 70-90parts by mass of polylactic acid, 5-30 parts by mass of a toughening agent, 0-20 parts by mass of a filler, 0.1-2 parts by mass of a lubricant, and 0.1-1 part by mass of a compatibilizer, wherein thetoughening agent is selected from one or more of poly(butyleneadipate-co-terephthalate), polycaprolactone, polyhydroxyalkanoate, polypropylene carbonate, an acrylate degradable polymer and a maleic anhydride grafted degradable polymer, and the compatilizer is selected from one or more of a silane coupling agent, an aluminate substance and a titanate substance. The bottom support component not onlymeets the use requirements of the balloon bottom support, but also can realize complete biodegradation. Meanwhile, the process is simple, the cost is low, and the market competitiveness of the product is stronger.

Description

Technical field [0001] The invention relates to the technical field of balloon support, in particular to a fully biodegradable balloon bottom support and a preparation method. Background technique [0002] Balloons are a common toy and decoration. In addition to holding the balloon directly at the inflatable binding port, the manufacturer has produced a support product that is convenient for holding and holding the balloon. The balloon support product is generally a balloon support rod composed of a rod body and a bottom support provided on the rod body; figure 1 It is a schematic diagram of the component structure of the existing balloon support rod, in which 1 is the bottom support and 2 is the rod body. The bottom support is directly in contact with the balloon and is mainly used to support the balloon; and the rod body is convenient for holding or fixing decoration. [0003] At present, the balloon base is mainly prepared by extrusion and injection molding of ordinary plastic...
