Description

Technical Field

[0001] The invention belongs to the technical field of composite mesh materials, and in particular relates to a high-efficiency luminous mesh material and a preparation method thereof. Background Art

[0002] Luminous mesh material, also known as luminous mesh cloth, can glow in the dark after absorbing light, and this luminous effect can be recycled indefinitely, making it a relatively environmentally friendly luminous material. It is widely used in performance costumes, props, safety clothing, home decoration and other fields. This type of material is usually composed of a luminous film and a mesh cloth. For example, the Chinese utility model patent with application number 201922439710.5 discloses a luminous mesh cloth, including a first luminous layer, a tensile layer, a mesh layer, an anti-tear layer and a second luminous layer, wherein the first luminous layer and the second luminous layer are coated with a fluorescent agent. This type of luminous mesh material that provides a fluorescent effect by coating a fluorescent agent is prone to the problem of partial disappearance of the fluorescent effect due to external reasons such as wear and tear during later use. There are also some methods that use luminous raw materials to make luminous masterbatches and then prepare luminous films, but the luminous films prepared by this method have problems such as weak luminescence and short luminescence persistence, and the luminous efficiency is not high enough. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a high-efficiency luminous mesh material with good luminous effect and a preparation method thereof.

[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is: a method for preparing a high-efficiency luminous mesh material, comprising the following steps:

[0005] S1. Mix all the raw materials except the luminous powder, add the luminous powder to 100-112°C and mix evenly to obtain a mixture, and the mixture is successively kneaded and calendered to obtain a luminous film;

[0006] S2. The luminous film, the white middle film, the mesh cloth and the black base film are laminated in the order from top to bottom to obtain a high-efficiency luminous mesh material.

[0007] The beneficial effect of the present invention is that by adjusting the order of adding materials during the preparation of the luminous film, the luminous efficiency of the obtained luminous mesh cloth is improved, so that the obtained luminous mesh material can emit brighter and longer-lasting light after absorbing light energy.

[0011] Figure 4 The figure shows a comparison of the luminous effects of a high-efficiency luminous mesh material in one embodiment of the specific implementation manner of the present invention and a pair of luminous mesh materials in a proportional manner. DETAILED DESCRIPTION

[0012] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in combination with the implementation modes and the accompanying drawings.

[0013] The preparation method of the high-efficiency luminous mesh material comprises the following steps:

[0014] S1. Stir and mix all the raw materials except the luminous powder until the material temperature rises to 100-112°C, then add the luminous powder and stir evenly to obtain a mixture, and the mixture is successively kneaded and rolled to obtain a luminous film (luminous transparent film);

[0015] S2. The luminous film, the white middle film, the mesh cloth and the black base film are laminated in the order from top to bottom to obtain a high-efficiency luminous mesh material.

[0016] From the above description, it can be seen that the beneficial effect of the present invention is that the preparation method provided by the present invention is different from the general method of mixing all raw materials, plasticizing, banburying and then rolling into a luminous film. Instead, all raw materials except the luminous powder are stirred and mixed at the feeding stage, and the luminous powder is added and stirred synchronously after the material temperature reaches 100-112°C, and then banburying and rolling are performed to form a film, so that the obtained luminous film has better luminous performance, can be made into a high-efficiency luminous sandwich material, and will not change the physical properties of the material. Compared with the luminous film prepared by the above general method, the luminous sandwich material made of the luminous film has a longer luminous time and higher brightness, and will not cause the local luminous effect to disappear due to wear during use. The preparation method can be directly adjusted and used in the original factory without adjusting the equipment, and is easy to promote and use on a large scale.

[0017] Furthermore, in S1, the luminous powder is added after the material temperature rises to 100-110°C, such as 101°C, 102°C, 103°C, 104°C, 106°C, 109°C, etc. During the entire stirring and mixing process, the material temperature is always less than 120°C, preferably maintained at 100-110°C. Too high a temperature will weaken the luminous effect.

[0018] Furthermore, the banburying temperature in S1 is 170-180° C., such as 171° C., 172° C., 173° C., 174° C., 176° C., and 180° C. Usually, the banburying temperature for preparing the luminous film is 180-190° C. By adjusting and lowering the banburying temperature, the luminous effect of the luminous material can be improved.

[0019] Furthermore, the luminous film includes the following raw materials, measured in parts by weight: 100 parts of PVC resin, 50 to 70 parts of plasticizer, 3 to 4 parts of stabilizer and 10 to 20 parts of luminous powder.

[0020] Furthermore, the white middle film includes the following raw materials, measured by weight: 100 parts of PVC resin, 50 to 70 parts of plasticizer, 10 to 20 parts of calcium carbonate, 3 to 4 parts of stabilizer and 2 to 4 parts of titanium dioxide.

[0021] The black base film comprises the following raw materials by weight: 100 parts of PVC resin, 50-70 parts of plasticizer, 10-20 parts of calcium carbonate, 3-4 parts of stabilizer and 0.5-1 part of carbon black powder.

[0022] As can be seen from the above description, the PVC white middle film and the PVC black base film can be made from the above raw materials according to the stirring temperature and the banburying temperature of S1, or commercially available products can be purchased and used directly for lamination.

[0023] The plasticizer is a commonly used plasticizer, such as DOP, DINP, and DOTP.

[0024] The PVC resin may have a degree of polymerization of 1300 or may be a PVC resin of other polymers.

[0025] The stabilizer is a liquid stabilizer, such as a barium zinc liquid stabilizer.

[0026] The mesh can be selected according to the needs of the actual application field. For example, the mesh can be 500D*18*17 plain woven polyester mesh, 250D*20*20 plain woven polyester mesh or 200D*300D*18*12 warp knitted polyester mesh.

[0027] The heating temperature during lamination is 170 to 180°C.

[0028] Luminous powder is rare earth luminous powder, that is, long afterglow rare earth light-storing luminescent material.

[0029] The present invention also provides a high-efficiency luminous mesh material, which is prepared by any of the above-mentioned methods for preparing the high-efficiency luminous mesh material.
