Description

Technical Field

[0001] The utility model relates to the technical field of hook and loop fasteners, in particular to a flame retardant hook and loop fastener. Background Art

[0002] Velcro, also known as hook and loop fasteners, male and female fasteners, mandarin duck fasteners and Velcro, was first used in the early 1980s. Its advantages of simple application, high viscosity, washability and quick bonding have been adopted by manufacturers in the clothing, footwear and hat industries. It is now widely used. The Velcro fastener has one hook surface and one velvet surface. The hook surfaces are neatly arranged, and the fixed angle of the hook cutting increases the probability of the buckle hair biting. The velvet surface is evenly brushed, not easy to break, and the horizontal bonding tension with the hook surface is firm and tight. The double-sided bonding can be reused up to 10,000 times or more, and the quality remains stable.

DETAILED DESCRIPTION

[0020] The utility model is further described below in conjunction with the accompanying drawings:

[0021] like Figure 1-Figure 5 As shown, the present embodiment provides a flame-retardant Velcro buckle, comprising an adhesive strip 1 which can stably bind objects and is resistant to pulling, a fixing ring 6 is installed on one side wall of the adhesive strip 1, a hook surface 2 and a hook surface 3 are respectively installed on one side wall of the adhesive strip 1, the hook surface 2 and the hook surface 3 are respectively located at the two ends of the adhesive strip 1, and a round surface 4 and a round surface 5 are respectively installed on the two side walls of the adhesive strip 1. When binding objects, the adhesive strip 1 is first tied to the surface of the object, and then the adhesive strip 1 is inserted into the fixing ring 6, and then the hook surface 2 and the round surface 4 on the adhesive strip 1 are fitted together, so that the objects can be preliminarily bound, and then one end of the adhesive strip 1 is turned 180° so that the hook surface 2 3 can fit with the round surface 2 5, so that the adhesive strip 1 can be further fixed, thereby improving the stability of the adhesive strip 1 when binding objects.

[0022] The adhesive strip 1 includes a strip inner layer 101, on which a reinforcing anti-pull rope 102 is arranged, and the reinforcing anti-pull rope 102 is located between two strip inner layers 101, and the two strip inner layers 101 are connected by hot melt adhesive. Hot melt adhesive is a plastic adhesive. Its physical state changes with temperature within a certain temperature range, while its chemical properties remain unchanged. It is non-toxic and tasteless, and is an environmentally friendly chemical product. It is popular because the product itself is solid, easy to package, transport, store, solvent-free, pollution-free, non-toxic, and has the advantages of simple production process, high added value, high bonding strength, and fast speed. The two reinforcing The tensile rope 102 fits together, so that the reinforced tensile rope 102 can be effectively sandwiched between the two inner layers 101 of the strips. The reinforced tensile rope 102 is made of polyester fiber. Polyester fiber, which is commonly known as "polyester", is a synthetic fiber made of organic dibasic acid and diol by chemical condensation. It is a kind of polymer compound. Polyester fiber has high strength and elastic recovery ability. Therefore, by using the reinforced tensile rope 102 inside the adhesive strip 1, the tensile performance of the adhesive strip 1 can be effectively improved, and it can also prevent the adhesive strip 1 from loosening the bound items due to the loss of elasticity of the adhesive tape buckle when the items are bound for a long time.

[0023] The inner layer 101 of the strip is made of nylon mixed with flame retardant. Flame retardant is a functional additive that imparts flame retardancy to flammable polymers. It is mainly designed for the flame retardancy of polymer materials and is mainly used for polymer materials such as plastics, rubber, fibers, etc. After nylon is mixed with flame retardant, it will have certain flame retardant properties. A flame retardant layer 103 is installed on one side wall of the inner layer 101 of the strip. The flame retardant layer 103 is made of aramid flame retardant fabric. Aramid fiber itself has non-combustibility, excellent chemical stability, excellent electrical insulation, long-lasting thermal stability and excellent mechanical properties. Therefore, aramid material has excellent fire retardant properties, arc resistance, chemical corrosion resistance, thermal protection, wear resistance and tearing properties. Therefore, the flame retardant layer 103 and the inner layer 101 of the strip made of nylon mixed flame retardant can effectively improve the flame retardant properties of the Velcro buckle.

[0024] A cotton and linen layer 104 is installed on one side wall of one of the reinforced tensile ropes 102. The cotton and linen layer 104 is made of cotton and linen. Cotton and linen refers to textiles with cotton and linen as raw materials. Cotton and linen are softer than nylon. Therefore, through the cotton and linen layer 104, the Velcro buckle can avoid crushing the surface of the objects when bundling them.

[0025] A plastic film layer 105 is installed on one side wall of another reinforced tensile rope 102. The plastic film layer 105 is made of a film made of polyvinyl chloride, polyethylene, polypropylene, polystyrene or other resins and is used as a coating layer. The plastic film layer 105 can prevent water stains from penetrating into the interior of the Velcro buckle, causing the interior of the Velcro buckle to become damp, which in turn causes the Velcro buckle to become moldy and affects the normal use of the Velcro buckle. In addition, the plastic film layer 105 makes it easy to wipe off stains on the surface of the Velcro buckle.

[0026] When the utility model is in use, the adhesive strip 1 is inserted into the fixing ring 6, and the hook surface 2 on the adhesive strip 1 is fitted with the round surface 4, so that the items are initially bundled, and then one end of the adhesive strip 1 is turned 180°, so that the hook surface 2 3 can fit with the round surface 2 5, so that the adhesive strip 1 can be further fixed, which is beneficial to improve the stability of the adhesive strip 1 when bundling items, and the reinforced tensile rope 102 inside the adhesive strip 1 can effectively improve the tensile performance of the adhesive strip 1, and can also prevent the adhesive strip 1 from loosening the bundled items due to the loss of elasticity of the adhesive tape buckle when the adhesive strip 1 is used to bundle items for a long time.
