Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of drop glue products, and relates to a hanging flow cup and a preparation method thereof. BACKGROUND

[0002] At present, in the application process of the drop glue cup, a mold is often used. Compared with the metal or plastic hard mold, the silica gel mold has more advantages due to its soft characteristics. The silica gel mold not only can protect the surface of the cured drop glue product and avoid secondary polishing, but also has the characteristics of easy demolding. In actual application, although the silica gel mold greatly reduces the production threshold and is convenient for manufacturing the drop glue cup, the silica gel mold is difficult to be mechanically produced and can only be demolded manually, especially for the products with complex structures.

[0003] Therefore, another application mode, i.e., the slotted drop glue, appears in the market. This processing mode is often used with an automatic drop glue machine. The more advanced one is equipped with a visual identification system, can break through the manual limit, does not need an additional mold, and can realize large-scale automatic production. However, this mode often requires that the cup body to be glued itself has a specific groove, and the cup body to be glued must be placed horizontally during the processing process and cannot be turned over before the glue solidifies. This mode has great selectivity and limitation for the cup body to be glued, and greatly limits the application of the drop glue, such as the production of some specific shapes of drop glue.

[0004] Apart from the traditional drop glue process, in terms of specific shapes, the UV printing process, i.e., the 4D printing process commonly used in the industry, has great advantages. There are mature machines and production processes on the market. However, the products of the UV printing process cannot simulate the smooth fillet transition of the drop glue cup and other characteristics of the drop glue products, which also limits the future development of the drop glue cup, such as the newly developed night light effect. Therefore, apart from other processes, we still need to develop some specific shapes of drop glue cups and their processing technology within the scope of the drop glue process. SUMMARY

[0005] The application aims at the above problems existing in the prior art, and provides a hanging flow cup with a natural night light flow hanging drop glue structure formed by gravity.

[0006] The application can be realized by the following technical scheme: a hanging flow cup, the hanging flow cup comprising a cup body and drop glue on the outer surface of the cup body, wherein the drop glue comprises the following raw materials in mass fraction: 15-30 parts of unsaturated polyester, 55-65 parts of epoxy resin, 15-30 parts of curing agent, and 1-15 parts of night light powder.

[0007] In the above hanging flow cup, the drop glue on the outer surface of the cup body is 1-9 strips of drop glue uniformly distributed along the cup opening, and the length of the drop glue is 30-90 mm.

[0008] As preferred, the cup body height of the present application is 214mm. In order to avoid the glue length being too short or too long, the glue length needs to be limited.

[0009] In the hanging cup, the curing agent comprises at least one of a fatty amine and a polyether amine.

[0010] In the hanging cup, the luminescent powder is strontium aluminate. The strontium aluminate is selected as the luminescent powder, which does not contain heavy metals and bisphenol A and the like in conventional luminescent powder. The strontium aluminate powder has a particle size of 20 microns or less, so that the best filling effect is achieved. The strontium aluminate can maintain high-brightness light emission for 1 hour and glow light emission for 8 hours.

[0011] In the hanging cup, the cup body comprises one of stainless steel 304 and styrene-acrylonitrile copolymer.

[0012] The present application also provides a preparation method of the hanging cup, which comprises the following steps:

[0013] S1, configuring the raw materials;

[0014] S2, uniformly stirring the unsaturated polyester, the epoxy resin, the curing agent and the luminescent powder to form a mixed glue solution, and dropping the mixed glue solution from top to bottom on the outer wall of the cup opening placed horizontally, wherein the cup body is rotated around the horizontal axis to complete the glue dropping, and finally curing treatment is performed.

[0015] In the preparation method of the hanging cup, 1-9 drops of the mixed glue solution are uniformly and interval dropped in the first circle, and the mixed glue solution is continuously and interval dropped in the second circle.

[0016] In the preparation method of the hanging cup, the total dropping amount of the mixed glue solution is 5-11.4wt% of the mass of the cup. The dropping amount of the glue dropping is controlled, so that the length of the glue dropping is controllable and the operation is convenient.

[0017] As preferred, the cup body needs to be cleaned with alcohol and electrostatic dust removal treatment once before glue dropping.

[0018] As preferred, the rotation speed of the cup body around the horizontal axis is 0.2 turns per second.

[0019] In the preparation method of the hanging cup, the curing treatment temperature is 50-70℃, and the time is 1-3h. The curing treatment temperature needs to be strictly controlled. When the curing temperature is too low (<50℃), the curing time is lengthened and the production cost is increased. When the curing temperature is too high (>70℃), the glue body will appear bubbles, which affects the appearance. The curing treatment temperature is controlled to be 50-70℃, so that the curing shape and length can be controlled to a certain extent, and the defects of excessive sagging and short sagging can be prevented.

[0020] Compared with the prior art, the drip cup of the present invention has the following advantages: The drip cup of the present invention relies on gravity to form a natural luminous drip structure, which does not require molds or grooves. The drip preparation can be carried out on a cup body with a smooth surface. By controlling the materials and processes, the selectivity of the products that can be processed is reduced. Moreover, the preparation method is simple and can be carried out on a large scale of industrial production. Attached Figure Description

[0026] The following are specific embodiments of the present invention, which further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0027] Example 1:

[0028] S1. The following raw materials are used: 20 parts unsaturated polyester, 60 parts epoxy resin, 20 parts curing agent, and 10 parts luminescent powder.

[0029] The unsaturated polyester is YX8202 (Sagging Art Paint A Agent) produced by Jinhua Yuxing Paint Factory;

[0030] The curing agent is YX8280 (B agent of sagging art paint) produced by Jinhua Yuxing Paint Factory;

[0031] The luminescent powder is made of aluminum oxide and strontium oxide.

[0032] S2, such as Figure 1 As shown, unsaturated polyester, epoxy resin, curing agent, and luminescent powder are uniformly stirred for 10 minutes to form a mixed adhesive. The mixed adhesive is then held vertically and... Figure 2 As shown, the mixture is dripped from top to bottom onto the outer wall of a horizontally placed cup. By rotating the cup around a horizontal axis, 6 drops of the mixed adhesive are dripped at even intervals in the first rotation, and the mixture is dripped continuously in the second rotation, with the total amount of adhesive dripped controlled at 10g. The AS cup is then placed vertically in a forced-air oven and baked at 60℃ for 2 hours. The product successfully cured, resulting in 6 drip streaks evenly distributed along the rim of the cup, with an average length of approximately 60mm, and exhibits a strong glow-in-the-dark effect. Figure 3The hanging cup is shown.

[0033] Example 2:

[0034] S1, configure the following raw materials: 20 parts of unsaturated polyester, 60 parts of epoxy resin, 5 parts of curing agent, 10 parts of night light powder.

[0035] The unsaturated polyester is YX8202 (hanging art paint A agent) produced by Jinhua Yuxing Paint Factory;

[0036] The curing agent is YX8280 (hanging art paint B agent) produced by Jinhua Yuxing Paint Factory;

[0037] The night light powder is strontium alumina.

[0038] S2, uniformly stir the unsaturated polyester, epoxy resin, curing agent and night light powder for 10 minutes to form a mixed glue solution. The mixed glue solution is vertically added from top to bottom on the outer wall of the cup mouth placed horizontally. By rotating the cup body around the horizontal axis, 6 drops of mixed glue solution are uniformly spaced in the first circle, and the mixed glue solution is continuously dropped in the second circle. The total amount of glue dropping is controlled to be 10wt% of the mass of the cup. Then the AS cup body is vertically placed in a blast oven and baked at 60°C for 2 hours. The product surface glue cannot be cured, and the product preparation fails.

[0039] Example 3:

[0040] S1, configure the following raw materials: 20 parts of unsaturated polyester, 60 parts of epoxy resin, 20 parts of curing agent, 10 parts of night light powder.

[0041] The unsaturated polyester is YX8202 (hanging art paint A agent) produced by Jinhua Yuxing Paint Factory;

[0042] The curing agent is YX8280 (hanging art paint B agent) produced by Jinhua Yuxing Paint Factory;

[0043] The night light powder is strontium alumina.

[0044] S2, uniformly stir the unsaturated polyester, epoxy resin, curing agent and night light powder for 10 minutes to form a mixed glue solution. The mixed glue solution is vertically added from top to bottom on the outer wall of the cup mouth placed horizontally. By rotating the cup body around the horizontal axis, 6 drops of mixed glue solution are uniformly spaced in the first circle, and the mixed glue solution is continuously dropped in the second circle. The total amount of glue dropping is controlled to be 10wt% of the mass of the cup. Then the AS cup body is vertically placed in a blast oven and baked at 60°C for 2 hours. The product successfully cures to have a vertical glue on the surface and at the end of the second circle, and the length of the vertical glue is about 50mm.

[0045] From Figure 4 It can be seen that when the first circle is completely controlled without adding mixed glue solution in example 3, the vertical glue cannot be smoothly formed.

[0046] Example 4:

[0047] The difference from Example 1 is that the total amount of the glue drops is controlled to be 3wt% of the cup mass.

[0048] From Figure 5 It can be seen that the total amount of the glue drops in Example 4 is controlled to be 3wt% of the cup mass, and the glue drops are relatively short as a whole.

[0049] Comparative Example 1:

[0050] The difference from Example 1 is that the amount of epoxy resin added is 50 parts.

[0051] Comparative Example 2:

[0052] The difference from Example 1 is that the amount of epoxy resin added is 70 parts.

[0053] Adhesion test:

[0054] A force meter is used to push any part of the glue drop layer with a force of 5kgf, and the part of the glue drop layer is not allowed to separate from the cup body.

[0055] 3M glue test:

[0056] A piece of 3M transparent tape is pasted on the glue drop layer, and is rolled flat to make full contact. After 90 seconds, it is torn off, and there should be no obvious peeling phenomenon.

[0057] Drop test:

[0058] At a height of 92cm, the bottom drops three times onto the felt laid on the cement floor (once on the side and once on the top), and no rupture, functional damage, and component separation, etc. are allowed to occur.

[0059] Alcohol test:

[0060] A white cloth soaked with 50% alcohol is used to wipe back and forth on the pattern and the glue drop layer for 50 times, and no discoloration phenomenon is allowed to occur.

[0061] High and low temperature test:

[0062] Temperature 54℃, humidity 95%, test for 24h; temperature 54℃, humidity 30%, test for 24h; temperature 0℃, humidity 0%, test for 24h; requirements: no deformation, discoloration, rupture, etc.
