Description

Technical Field

[0001] The utility model relates to a latex thread, in particular to a flame-retardant graphene composite latex ribbon. Background Art

[0002] Latex is a natural rubber product, the main component of which is cis-polyisoprene. It has excellent elasticity, insulation, water-proofing and plasticity, high tensile strength, good tear resistance and wear resistance, and is easy to bond with other materials. It is an essential raw material for elastic bands and clothing accessories, and is mainly used to make elastic fabrics, such as elastic bands, tights, swimsuits, etc. However, the existing latex thread is usually a solid single-layer structure composed of latex. The outer diameter of the latex thread is generally fixed, with a certain strength and strong deformation resistance. The required width of the latex thread cannot be cut at will. The force required to pull the latex thread is large, and it is not convenient to use. In addition, the structure of the latex thread is relatively simple, and the single material leads to a relatively single function. Its material characteristics make the latex thread prone to aging, cracking, discoloration, etc. in the air, and it is also easy to become sticky in a high temperature environment, affecting its performance.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0018] Example:

[0019] like Figure 1 and Figure 2As shown, a flame retardant graphene composite latex ribbon comprises a plurality of latex threads 1 arranged in a straight line, a tearable portion 2 is formed between adjacent latex threads 1, and serrated tear notches 21 are provided on the upper and lower sides of the tearable portion 2; the latex thread 1 comprises a graphene composite latex core layer 11, a magnetic graphene layer 12, a heat insulation layer 13 and a flame retardant layer 14 arranged in sequence from the inside to the outside, and at least two cavities 111 are provided inside the graphene composite latex core layer 11, and an elastic thread 112 is provided in at least one cavity 111.

[0020] The utility model utilizes a tearable portion 2 to combine a plurality of latex threads 1. When in use, the tear notch 21 of the tearable portion 2 at any position can be directly torn to tear the latex ribbon into a plurality of latex threads 1, which is convenient for taking according to actual needs and is easy to use. A graphene composite latex core layer 11 is adopted to improve the strength and air permeability of the latex thread 1, and provide good flame retardant and heat dissipation performance. A magnetic graphene layer 12 is arranged on the outside of the graphene composite latex core layer 11. There are many active points on the surface of the magnetic graphene layer 12, which can be used as a vulcanization accelerator to improve the overall vulcanization density, ensure the stability of the mechanical properties of the latex thread 1 after vulcanization molding, reduce the vulcanization temperature, and reduce the scorch time and heat dissipation performance. The vulcanization time is positive, and the production efficiency is improved; the heat insulation layer 13 is set to cooperate with the cavity 111 inside the graphene composite latex core layer 11, which can play a heat insulation role and reduce the impact of the high temperature environment on the graphene composite latex core layer 11; the flame retardant layer 14 is set to provide flame retardant performance for the latex thread 1; multiple cavities 111 and elastic threads 112 set in the cavities 111 are set to improve the expansion and contraction performance and expansion space of the latex thread 1, and the elastic thread 112 also plays a role of a skeleton in the latex thread 1, which improves the overall strength and toughness of the latex thread 1, and prolongs the service life of the latex thread 1, so that the latex thread 1 is not easy to break during use, which meets the requirements of high-strength products.

[0021] The thickness of the tearable portion 2 is less than the thickness of the latex thread 1, so it is easy to tear.

[0022] The tearable portion 2 comprises a tearable base layer 22, and foam layers 23 are attached to the upper and lower surfaces of the tearable base layer 22. The foam layer 23 has the function of protecting and buffering the tearable portion 2 to prevent it from cracking when it is not pulled.

[0023] The tearable base layer 22 is made of polypropylene film, polyester film or polyethylene film.

[0024] The heat insulation layer 13 is a nano-aerogel layer. The flame retardant layer 14 is a talcum powder layer containing an ultraviolet absorber. The elastic yarn 112 is a spandex filament.
