Description

Technical Field

[0001] The present application relates to the field of sanitary ceramics, and in particular to a filter for a urinal and a manufacturing method thereof. Background Art

[0002] Currently, the male urinals on the market for receiving urine are mainly made of sanitary ceramics. Such urinals are usually equipped with filters, which can effectively filter out impurities such as pebbles, leaves, paper scraps, sand, etc., to prevent these impurities from entering the pipes and reduce the risk of pipe blockage.

[0003] However, the existing filters used in urinals are basically made of sanitary ceramics, which are easy to fall off and cause damage when cleaning; in addition, this type of filter has poor antibacterial effect, which is not conducive to the health of people using the urinal.

[0004] Therefore, there is a need for a filter that is drop-resistant, sterilizing and used in a urinal and a method for making the same. Summary of the invention

[0005] The following is an overview of the subject matter described in detail herein. This overview is not intended to limit the scope of protection of this application.

[0006] In one aspect, the present application provides a filter for a urinal, the filter being made of the following materials, the materials comprising, by weight, 15-23 parts of bisphenol A epoxy resin, 50-57 parts of waste ceramic powder, 20-25 parts of glass fiber, 1-3 parts of low shrinkage agent, 0.2-0.4 parts of curing agent, 0.8-1.1 parts of initiator, and 1-2.5 parts of inorganic composite bactericide; The low shrinkage agent is modified polyurethane or polyvinyl chloride; The inorganic composite fungicide consists of 31-35 parts of quartz, 14-18 parts of aluminum oxide, 17-22 parts of thorium dioxide, 7-12 parts of tourmaline, 5-8 parts of samarium trioxide, 7-9 parts of thulium trioxide and 8-12 parts of zinc oxide in parts by weight.

[0007] In one embodiment, the material may include, by weight, 17-21 parts of bisphenol A epoxy resin, 52-56 parts of waste ceramic powder, 21-24 parts of glass fiber, 1.5-2.5 parts of low shrinkage agent, 0.25-0.35 parts of curing agent, 0.95-1.05 parts of initiator and 1.4-2.1 parts of inorganic composite fungicide.

[0008] In one embodiment, the waste ceramic powder may consist of 59.2-65.2 parts of SiO2, 19.5-25.3 parts of Al2O3, 0.9-2.5 parts of CaO, 0.2-1.2 parts of MgO, 1.3-3.2 parts of K2O and 0.9-1.6 parts of Na2O by weight.

[0009] In one embodiment, the particle size of the waste ceramic powder may be in the range of 120-200 mesh.

[0010] In one embodiment, the curing agent may be maleic anhydride.

[0011] In one embodiment, the initiator may be tert-butyl perbenzoate.

[0012] In one embodiment, the modified polyurethane may be acrylate-modified polyurethane.

[0013] In another aspect, the present application also provides a method for manufacturing the above filter, comprising the following steps: 1) Weigh each component; 2) mixing the waste ceramic powder, the inorganic composite fungicide and the initiator to obtain a first material; 3) mixing the epoxy resin, the low shrinkage agent and the curing agent to obtain a second material; 4) adding the second material to the first material and mixing to obtain a third material; 5) adding the glass fiber to the third material and mixing to obtain a fourth material; 6) Hot pressing the fourth material at a temperature range of 170° C. to 180° C. to obtain the filter.

[0014] In one embodiment, the mixing method in step 2), step 4) and step 5) is kneading in a kneader.

[0015] The present application achieves the technical effect of anti-falling by adopting a specific combination of a low shrinkage agent and a low-cost bisphenol A epoxy resin with high strength, high compressive strength, good corrosion resistance and chemical resistance to play a bonding role.

[0016] The present application achieves ceramic texture by introducing waste ceramic powder and glass fiber. Waste ceramic powder replaces alumina, which can reduce resource waste and save costs.

[0017] The present application uses a combination of specific inorganic bactericidal materials to achieve a non-contact antibacterial process, sterilizing bacteria that do not directly contact the filter, with excellent results and a sterilization rate of over 99.9%.

[0018] Other features and advantages of the present application will be described in the following description, and partly become apparent from the description, or be understood by implementing the present application.

[0028] Example 3 The inorganic composite fungicide in this embodiment is composed of 32% quartz, 15% alumina, 19% thorium dioxide, 8% tourmaline, 6% samarium trioxide, 9% thulium trioxide and 11% zinc oxide.

[0029] 50 parts by weight of waste ceramic powder, 2.5 parts by weight of inorganic composite fungicide and 1.1 parts by weight of initiator tert-butyl perbenzoate are added into a kneader and kneaded for 8 minutes to obtain a first material; Mix 23 parts by weight of bisphenol A epoxy resin, 3 parts by weight of low shrinkage agent polyvinyl chloride, and 0.4 parts by weight of curing agent maleic anhydride to obtain a second material; Add the second material into the kneader and knead it with the first material for 10 minutes to obtain the third material; Adding 20 parts by weight of glass fiber into a kneader and kneading with the third material for 12 minutes to obtain a fourth material; The fourth material is hot-pressed at a temperature of 170-180° C. to obtain a drop-resistant and sterilizing filter.

[0030] Comparative Example 1 A sanitary ceramic filter of model 13071 manufactured by Jomoo Kitchen & Bathroom Co., Ltd. was selected. The filter does not contain the specific combination of epoxy resin and low shrinkage agent of the present application, nor does it contain the specific inorganic composite bactericide of the present application.

[0031] Comparative Example 2 The materials used in this comparative example include 19 parts by weight of bisphenol A epoxy resin, 54 parts by weight of waste ceramic powder, 22 parts by weight of glass fiber, 2 parts by weight of low shrinkage agent modified polyurethane, 0.3 parts by weight of curing agent and 1 part by weight of initiator, and no inorganic composite fungicide is added. The preparation method is the same as Example 2.

[0032] Performance Testing 1. Drop test The filters prepared in the examples and comparative examples were dropped freely from a height of 1 meter, and the filters were visually observed to see if they were damaged. The results are shown in Table 1.

[0033] Table 1

[0034] It can be seen from the results in Table 1 that the filter of Comparative Example 1 is seriously damaged; however, in the present application, the specific combination of epoxy resin and low shrinkage agent has an excellent bonding effect, so that the manufactured filter is intact and shows excellent drop resistance.

[0035] 2. Antibacterial test The antibacterial properties and antibacterial durability of the filters prepared in the embodiments and comparative examples were tested according to the antibacterial performance of antibacterial ceramic products JC / T897 2014. The results are shown in Table 2.

[0036] Table 2

[0037] From the results in Table 2, it can be seen that with the addition of inorganic bactericides, the antibacterial performance of the filter can be greatly improved. When 1.7wt% of the inorganic composite bactericide is added (Example 2), the antibacterial rate of the product can be increased to more than 99.9%. On the contrary, the filter products of Comparative Examples 1 and 2 that do not contain the specific inorganic composite bactericide of the present application have very poor antibacterial performance.

[0038] Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present application. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present application.
