Description

Technical Field

[0001] This utility model relates to the field of epoxy dry-hanging adhesive packaging technology, specifically to a deodorizing device for packaging barrels. Background Technology

[0002] Epoxy dry-hanging adhesive is a convenient adhesive product with excellent mechanical and adhesive properties, widely used in construction engineering and decoration. Especially with the development of the petrochemical industry, its production cost has gradually decreased, leading to its gradual replacement of traditional cement-based cementitious materials in decoration projects. Epoxy dry-hanging adhesives used in construction and decoration are generally room-temperature amine-curing systems (commonly known as AB adhesives), typically consisting of two components, A and B. Component A comprises epoxy resin, diluent, and fillers, while component B comprises amine curing agents, additives, and fillers. The diluent and amine curing agent components inevitably contain varying amounts of volatile organic compounds (VOCs). Therefore, these VOC small-molecule gases accumulate in the upper space of the sealed container of epoxy dry-hanging adhesive. When the container is opened, the pungent odor of these gases creates an extremely unpleasant construction experience for on-site workers and is harmful to their health. Utility Model Content

[0003] To overcome the shortcomings of the above-mentioned technologies, the purpose of this utility model is to provide a deodorizing device for packaging barrels, which solves the problem of strong odor when packaging barrels containing volatile components are opened, and can effectively reduce the odor when opening the packaging barrels.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A deodorizing device for a packaging barrel, the packaging barrel comprising a barrel body and a barrel lid sealed on top of the barrel body, the barrel body containing a product, characterized in that: the deodorizing device is fixedly installed inside the barrel lid; the deodorizing device comprises:

[0006] A container is provided with a first vent hole, and one end of the container is fixedly connected to the bucket lid;

[0007] The adsorption component is installed inside the accommodating box.

[0008] As a preferred embodiment, a partition is provided on the inner side wall of the container, dividing the container into two chambers; the adsorption component is installed in the chamber inside the container near the lid. Installing the adsorption component in the chamber away from the product inside the packaging barrel prevents the product inside the packaging barrel from contacting the adsorption component when the packaging barrel is shaken, while the other chamber, closer to the product inside the packaging barrel, effectively prevents the product inside the barrel from contacting the adsorption component when the packaging barrel is shaken.

[0009] Furthermore, a second vent is provided on the partition. The vent is provided on the container and the partition to allow volatile components to enter the container and be adsorbed by the adsorption component.

[0010] As a preferred embodiment, the container includes a first box body and a second box body; the first box body and the second box body are detachably connected; one end of the first box body is fixedly connected to the inside of the bucket lid, and the other end is open and detachably connected to the second box body; a partition is provided on the end of the second box body connected to the first box body; the first box body and the partition form a chamber near the bucket lid, and the second box body is another chamber near the product inside the packaging bucket; the adsorption component is installed in the first box body. The detachable connection between the first box body and the second box body facilitates the recycling of the container. By disassembling the first box body and the second box body, replacing the adsorption component in the first box body, and reassembling the first box body and the second box body, the container can be reused.

[0011] Furthermore, the first box and the second box are snap-fitted together.

[0012] As a preferred embodiment, the adsorption component is an active adsorption material package.

[0013] Furthermore, the activated adsorbent material package contains activated carbon and / or polyacrylic acid solid particles. The activated carbon can physically adsorb volatile gas molecules within the packaging container, while the polyacrylic acid solid particles can chemically adsorb epoxy components and amines.

[0014] As a preferred embodiment, the end face of the container that connects to the bucket lid is fitted and fixed to the inner side of the bucket lid.

[0015] Furthermore, the bonding and fixing is achieved by adhesive bonding.

[0016] Furthermore, the bonding is achieved using double-sided self-adhesive adhesive. The size and area of ​​the double-sided self-adhesive adhesive are comparable to the size of the container, and it must have good adhesion and strength to withstand the weight of the container and the absorbent material package as a whole, and it should not easily fall off.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This utility model relates to an odor-removing device for epoxy dry-hanging adhesive packaging drums, solving the problem of strong odor when opening packaging drums containing volatile components. It is convenient to use and effectively absorbs volatile gases inside the packaging drum, reducing the odor upon opening. This utility model is mainly used for improving the odor removal of packaging drums for paste adhesives such as epoxy dry-hanging adhesives. It can effectively block the vents of the paste adhesive to achieve an odor-removing effect. It is not suitable for other liquid products. Attached Figure Description

[0026] To better explain this utility model, the main contents of this utility model are further illustrated below with reference to specific embodiments, but the contents of this utility model are not limited to the following embodiments.

[0027] like Figure 1 As shown, the epoxy dry-hanging adhesive packaging bucket includes a bucket body 5 and a bucket lid 4 sealed and installed on the top of the bucket body 5. The bucket body 5 contains epoxy dry-hanging adhesive 6. Normally, a certain space is reserved between the epoxy dry-hanging adhesive 6 and the bucket lid 4. This utility model provides a packaging bucket odor-eliminating device, fixedly installed inside the bucket lid 4 of the bucket body 5, including: a receiving box 1, the receiving box 1 having a first vent hole 101, and one end face of the receiving box 1 being fitted and fixed to the inner side of the bucket lid 4. The odor-eliminating device also includes an adsorption component 2, installed inside the receiving box 1.

[0028] like Figure 2 and Figure 3 As shown, a partition 3 is provided on the inner side wall of the container 1, dividing the container 1 into upper and lower chambers; the adsorption assembly 2 is installed in the upper chamber of the container 1 near the lid 4.

[0029] Specifically, the containing box 1 includes a first box body 102 and a second box body 103; the first box body 102 and the partition 3 form an upper chamber near the lid 4, and the second box body 103 forms a lower chamber near the product inside the packaging barrel. The first box body 102 and the second box body 103 are detachably connected. One end of the first box body 102 is fixed to the inside of the lid 4, and the other end is open and detachably connected to the second box body 103; the partition 3 is provided on the end of the second box body 103 that is connected to the first box body 102; the adsorption assembly 2 is installed inside the first box body 102.

[0030] More specifically, the first box 102 and the second box 103 are connected by a snap-fit: the outer walls of the first box 102 and the second box 103 are provided with snap-fit ​​7, and the two are snap-fitted together by the snap-fit ​​7.

[0031] The container 1 is cylindrical, and the first vent 101 is located on the side wall of the container 1 and on the end face away from the lid 4. In actual use, the size of the first vent 101 must ensure that the colloid can flow in or out smoothly through the first vent 101. It can provide ventilation while also acting as a barrier to prevent the vent of the basket from being sealed by the colloid due to vibration or inversion of the packaging barrel, thus rendering it ineffective.

[0032] like Figure 4 As shown, a second vent 301 is provided on the partition 3. The pore size of the second vent 301 is smaller than that of the active adsorbent material, ensuring that the adsorbent material will not leak.

[0033] The adsorption component 2 is as follows: Figure 5 The activated adsorbent material package shown contains activated carbon and / or polyacrylic acid solid particles.

[0034] The accommodating box 1 and the inner side of the bucket lid 4 are connected by, for example Figure 6 The double-sided self-adhesive tape shown is connected in section 8.

[0035] The container 1 is made of plastic.

[0036] This invention can be used for odor removal from packaging containers of epoxy dry-hanging adhesives and other paste-like adhesives. After the odor removal device is fixedly connected to the container lid 4, the container lid 4 is sealed and installed at the top of the container body 5. A certain distance is reserved between the container box 1 and the epoxy dry-hanging adhesive 6 inside the container to absorb volatile substances inside the container body 5.

[0037] Examples 1-7 and Comparative Example 1

[0038] The above-mentioned deodorizing device for packaging barrels is used for epoxy dry-hanging adhesive packaging barrels.

[0039] In Examples 1-7 and Comparative Example 1, the weight of epoxy dry-hanging adhesive in the packaging barrel was 18 kg (9 kg each for Group A and Group B), and the barrel volume was 10 L. In Examples 1-7, a deodorizing device was installed inside the packaging barrel. In Examples 1-3, the active adsorbent was activated carbon, with activated carbon contents of 100 g, 200 g, and 300 g, respectively. In Examples 4-6, the active adsorbent was activated carbon and polyacrylic acid solid particles, with activated carbon content of 100 g and polyacrylic acid solid particle content of 10 g, 20 g, and 30 g, respectively. In Example 7, the active adsorbent was polyacrylic acid solid particles with a content of 20 g. Comparative Example 1 used a commercially available epoxy dry-hanging adhesive packaging barrel. Three sets of tests were conducted for each example and comparative example. The odor effect after opening was tested, and the odor level test referred to: HGT4065-2008 / Odor Evaluation Method for Adhesives. The test results are shown in Table 1.

[0040] Table 1: Odor Evaluation Effect Tests of Examples and Comparative Examples

[0041]

[0042] The comparative examples show that the odor of epoxy dry-hanging adhesive in the barrel increases with prolonged storage time. Examples 1, 2, and 3 all verify that the packaging barrel of this invention has a significant effect on reducing odor. The comparison of Examples 1, 2, and 3 shows that increasing the amount of activated carbon can extend the storage time of the dry-hanging adhesive and reduce the odor in the barrel; however, a larger amount of activated carbon results in a larger storage container. The comparison of Examples 1, 4, 5, and 6 shows that the chemical adsorption effect of polyacrylic acid solid particles is better, which can reduce the amount of activated carbon used. The comparison of Examples 5 and 7 shows that polyacrylic acid solid particles can only adsorb some specific substances, and the adsorption effect on other volatile substances is not ideal. Example 5 demonstrates that the combination of activated carbon and polyacrylic acid solid particles can achieve the best odor reduction effect, while reducing the amount of activated carbon to reduce the size of the storage container, thereby improving product quality. The adsorption reaction equation for the polyacrylic acid solid particles is as follows:

[0043]

[0044] The above description is merely a specific embodiment of this utility model. In actual use, the weight and ratio of the two adsorbent materials need to be adjusted according to the specific product and weight. Any other parts not described are considered prior art.
