Technical Field

[0001] The invention relates to the field of spring wires, and in particular to a spring wire formed by integrating a thermoplastic elastomer and silicone. Background Art

[0002] Spring wire, also known as slingshot wire and spiral wire, is a device connecting wire that works by using scalability; in the structural setting of the spring wire, its two ends extend out as connecting ends, and the middle part is the curled part. This structural setting allows the wire body to shrink when not in use, thereby reducing the area of ​​use, and the rope length can be flexibly changed when it needs to be stretched for use. The existing surface of this type of wire structure adopts a smooth structural treatment. This setting makes the curled part of the spring wire body lack restraint, so that the curled part of the wire body is not protected when the wire body is used, and then the curled part of the spring wire body is deformed, and then the wire body is inflexible when stretched. Therefore, this scheme proposes to fuse thermoplastic elastomer and silicone into an integrated spring wire to solve the above problems. Summary of the invention

[0021] In the figure: 1, spring wire body; 101, raised plug post; 102, ball block. DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] Embodiment 1, the present invention provides as follows Figure 1 The thermoplastic elastomer and silicone are fused into an integrated spring wire, including a spring wire body 1, and also including:

[0024] A convex structure, wherein a plurality of groups of convex structures are arranged in a vertical direction around the outer wall of the spring wire body 1;

[0025] Specifically, the protruding structure includes protruding posts 101 , and one end of each of the protruding posts 101 is fixedly connected to the outer wall of the spring wire body 1 .

[0026] It should be noted that the multiple raised posts 101 arranged on the outer wall of the spring wire body 1 are on the same vertical line, which can also ensure that the circle diameters of the winding part of the spring wire body 1 are the same in the vertical direction.

[0027] It should be noted that when the spring wire body 1 is in use, some sleeve structures can be added to carry out the sleeve arrangement of the raised structure, so that the curled portion of the spring wire body 1 can be conveniently restricted and bound, and the sleeve structure needs to have a ball groove, and the shape of the ball groove is adapted to the shape of the ball block 102, so that after the ball block 102 is inserted into the ball groove, the ball block 102 can be bound by the sleeve of the ball groove, so that the curled portion of the spring wire body 1 can be bound.

[0028] In the second embodiment, the present invention provides a preparation formula for a spring wire integrated with a thermoplastic elastomer and silicone, which is used to prepare the spring wire of the first embodiment, and is prepared from the following raw materials in proportion by mass, including 70% to 80% thermoplastic elastomer, 10% to 15% neodymium iron boron, 5% to 10% samarium iron nitrogen, 5% to 10% silicone, 0.5% to 1% plasticizer, 2% to 4% filler, 0.5% to 1% antioxidant, 0.5% to 1% flow aid, 0.2% to 0.5% promoter and 1% to 2% organic pigment.

[0029] Specifically, the thermoplastic elastomer includes one or more of styrene-ethylene-butylene copolymer and styrene-ethylene-polyether copolymer;

[0030] It should be noted that styrene-ethylene-butene copolymer (SEBS) and styrene-ethylene-polyether copolymer (SEEPS) are both thermoplastic elastomers (TPE), among which SEBS is a thermoplastic elastomer copolymerized by styrene, ethylene and butene, and its molecular structure contains the rigid part of styrene and the flexible part of ethylene-butene. SEBS has good heat resistance, weather resistance, UV resistance, as well as excellent elasticity and flexibility, and its hardness is adjustable; SEEPS is a copolymer of styrene, ethylene and polyether, and the polyether chain segment provides better flexibility and low temperature resistance. SEEPS has good water resistance and chemical resistance, and can still maintain good elasticity at low temperatures.

[0031] Silicone includes room temperature vulcanized silicone, and different hardness levels can be selected according to needs;

[0032] The particle size of NdFeB is 1μm-5μm, and its particle size is determined by the required magnetic properties. NdFeB is a strong permanent magnetic material composed of neodymium (Nd), iron (Fe) and boron (B). This material has excellent magnetic properties;

[0033] The particle size of SmFeN is 2μm-3μm, which ensures good dispersion according to the set size.

[0034] Specifically, plasticizers include phthalates and vegetable oils, wherein phthalates are used to improve the flexibility and processing properties of TPE, and vegetable oils are not only environmentally friendly but also can improve elasticity and processing properties;

[0035] Fillers include calcium carbonate and talc, which improve the rigidity of the material;

[0036] Antioxidants include butylated hydroxytoluene, which improves thermal stability and antioxidant properties. Butylated hydroxytoluene is a synthetic antioxidant commonly used in food, cosmetics and plastics to prevent the oxidation of fats and oils. Its mechanism of action is to capture free radicals and prevent them from oxidizing other molecules.

[0037] The flow aid includes one or more of polyethylene wax and polypropylene wax, which is used to improve the fluidity of the material during processing;

[0038] The accelerator includes one or more of tetramethylthiourea disulfide and dicyclohexylbenzothiazolesulfonamide.

[0039] It should be noted that tetramethylthiourea disulfide (TMTD) is a commonly used vulcanization accelerator with good vulcanization acceleration effect and thermal stability. It can react with sulfur to increase the cross-linking degree of rubber, thereby improving the elasticity, wear resistance and aging resistance of rubber. TMTD also has anti-corrosion and anti-oxidation properties.

[0040] Dicyclohexylbenzthiazolesulfonamide (DCBS) is a highly efficient vulcanization accelerator, commonly used in the vulcanization process of natural rubber and synthetic rubber. It can promote the vulcanization reaction at a lower temperature and improve the processing performance and final performance of the rubber. The spring wire prepared by this scheme has the characteristics of environmental protection, cold resistance, temperature resistance, flame retardancy, magnetic attraction, easy storage and fast rebound.

[0041] In the third embodiment, the thermoplastic elastomer and silicone rubber are fused into an integrated spring wire, which comprises the following preparation steps:

[0042] The first step is mixing: thermoplastic elastomer (TPE), neodymium iron boron, samarium iron nitrogen, silica gel, plasticizer, filler, antioxidant, flow aid, promoter and organic pigment are weighed according to the proportion of Example 2, and fully mixed in a high-speed mixer to ensure that each component is evenly dispersed.

[0043] The second step is extrusion molding: the mixture is fed into the extruder for extrusion molding, and the temperature and pressure are controlled to maintain the fluidity and performance of the material. After extrusion, it can be cut into spring wires of the required length.

[0044] The third step is vulcanization treatment: According to the type of silicone, vulcanization treatment is carried out to enhance the strength and elasticity of the material.

[0045] Step 4: Cooling and shaping: The spring wire is cooled naturally after extrusion to ensure the stability of its shape and size.

[0046] Step 5, post-processing: Surface treatment is performed as required, including spraying and coating, to improve wear resistance and aesthetics.

[0047] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein.
