TABLE 1
As can be seen from Table 1, the samples which are placed for 24 hours after the inoculation of the antibacterial test piece are compared with the samples which are directly obtained after the inoculation of the non-processed test piece and the samples which are placed for 24 hours after the inoculation of the non-processed test piece, so that the obtained Escherichia coli and staphylococcus aureus are greatly reduced; the antibacterial performance values of the samples which are placed for 24 hours after the antibacterial sample pieces are inoculated to escherichia coli and staphylococcus aureus are respectively more than 5.9 and more than 5.0, and meanwhile, the antibacterial rates to the escherichia coli and the staphylococcus aureus are respectively more than 99.9%. The nano silver ions in the components have strong inhibiting and killing effects on dozens of pathogenic microorganisms such as escherichia coli, gonococcus, chlamydia trachomatis and the like, and show high antibacterial activity on microorganisms such as bacteria, mold, spores, yeast and the like. The components of the fumed silica play a role in reinforcing.
Therefore, the silica gel bra can greatly inhibit escherichia coli and staphylococcus aureus and has a good antibacterial effect.
Durability test: the durability of the high tear-resistant silicone rubber is determined according to the national standard control standard of low-hardness silicone rubber. The results are shown in table 2:
| detecting items | Detection standard (GB/T) | High tear-resistant silicone rubber |
| Appearance of the product | / | Semi-transparent |
| Vulcanizing agent | / | C-8 |
| Addition amount (%) | / | 2.0 |
| Vulcanization conditions | / | 170℃×5Min |
| Hardness (Shao) | GB/T531.1-2008 | 18-22 |
| Tensile strength (MPa) not less than | GB/T528-2009 | ≥3.0 |
| Elongation (%) not less than | GB/T528-2009 | ≥700 |
| The permanent deformation (%) of the stretch film is less than or equal to | GB/T528-1998 | ≤10.0 |
| Tear strength is not less than | GB/T529-2008 | ≥8.0 |
TABLE 2
As can be seen from Table 2, the high tear resistance silicone rubber has a hardness of 18-22 degrees, a tensile strength of 3.0MPa or more, an elongation of 700% or more, a tensile set of 10.0 or less, and a tear strength of 8.0 or more. As can be seen from the test, the hardness of the product is soft enough, and simultaneously the tensile strength, the tearing strength, the tensile permanent deformation and the like of the product meet the requirements of national standards. The methyl vinyl silicone rubber in the components is copolymerized by dimethyl siloxane and a small amount of vinyl siloxane, and the introduction of a small amount of unsaturated vinyl greatly improves the vulcanization process and the performance of a finished product, particularly the heat aging resistance and the high-temperature compression deformation resistance; the fumed silica can improve the strength, wear resistance and aging resistance of the product, and plays a role in reinforcement.
Therefore, the silica gel bra has low hardness, good stretching resistance and tearing resistance and good durability.
The organic silicon antistatic agent consists of methyl silicone oil and lithium bis (trifluoromethanesulfonyl) imide. The methyl silicone oil has excellent electrical insulation; the lithium bis (trifluoromethanesulfonyl) imide is generally used as an organic electrolyte lithium salt of a lithium ion battery and has high electrochemical stability and conductivity, and the application of the lithium bis (trifluoromethanesulfonyl) imide to an antistatic agent shows that the antistatic effect is obvious.
At present, the detection of the static suppression effect in industry evaluation basically adopts a physical comparison method, namely, products without adding the static agent and products with the static agent are placed at about 1cm above the cigarette ash at the same time, the quantity of the adsorbed cigarette ash is observed to be compared, and the product of the invention and the products without adding the static agent are tested, so that the quantity of the cigarette ash adsorbed by the product of the invention is far less than that adsorbed by the products without adding the static agent, and therefore, the product of the invention has good antistatic performance.
The silica gel hand feeling oil consists of methyl vinyl silicone rubber, kerosene, silicon dioxide and a platinum vulcanizing agent. The methyl vinyl silicone rubber is polydimethyl methyl vinyl siloxane, is used as a raw material in the silica gel hand feeling oil, is matched with other materials to prepare the hand feeling oil, and plays a role in insulation and lubrication. The kerosene has the characteristics of dissolution, lubrication and reduced permeability, so that the silicon rubber is easy to form a film in the subsequent processing procedure and has good compactness; the silicon dioxide is an excellent flow promoter, can be used as an anti-adhesion agent, and well enhances the anti-adhesion property of the product; the platinum vulcanizing agent has the characteristics of low vulcanizing temperature, high vulcanizing speed and full intermolecular crosslinking of the product after vulcanization molding. Therefore, the product of the invention has good hand feeling and reduces the friction coefficient with clothes when the product outer cup is worn.
