Description
Technical Field
The invention belongs to the technical field of organic chemistry, and particularly relates to an anti-tarnish agent composite composition and application thereof.
Background
Ketoxime silane is often used as a vulcanizing agent and a cross-linking agent of room-temperature vulcanized silicone rubber, and also used as an accelerator for adhesion of plastics, nylon, ceramics, glass and the like with silicone rubber. Ketoximosilanes include the following compounds: methyl tributyrinoxime silane, vinyl tributyrinoxime silane, propyl tributyrinoxime silane, tetrabutoximino silane, phenyl tributyrinoxime silane, dimethyl dibutyloximino silane, methyl vinyl dibutyloximino silane, methyl tris (methyl isobutyl ketoximo) silane, vinyl tris (methyl isobutyl ketoximo) silane, tetrakis (methyl isobutyl ketoximo) silane, methyl vinyl bis (methyl isobutyl ketoximo) silane, methyl triacetoneximo silane, vinyl triacetoneximo silane, dimethyl diacetone ketoximo silane, methyl vinyl diacetone ketoximo silane, the ketoximo silanes containing a particular chemical structure of ketoximo groups that leads to the development of a dark color during storage, are specifically represented by methyl tributyrinoxime silane, propyl tributyrinoxime silane, tetrabutoximino silane, The color of compounds such as dimethyl-dibutyloximino silane is changed from 30-60-one after 6-8 months at the fastest speed in the normal-temperature storage process; the color of the compound such as vinyl tributyrinoxime silane, phenyl tributyrinoxime silane, methyl vinyl dibutyloximino silane, vinyl tri (methyl isobutyl ketoximino) silane and the like is changed from 30-60-one after 1-2 months at the fastest speed in the normal-temperature storage process; similar phenomena as above also occur with other ketoximosilanes.
The main reason for the discoloration of the ketoxime silane substances is caused by the special electron cloud structure of the ketoxime groups, and the vinyl tributyrinoxime silane and other substances not only have the electron cloud structure of the ketoxime groups, but also have the conjugated electron cloud effect of the vinyl groups, and the combined action of the two causes the vinyl tributyrinoxime silane to be relatively easy to discolor. The characteristic of easy discoloration causes the appearance quality of ketoxime silane to change along with the prolonging of time in the storage process, or causes the color, the appearance and the property of downstream products (room temperature vulcanized silicone rubber) to change in the storage process, so that the application of the ketoxime silane is limited.
At present, the application of an antioxidant in the aspect of color change prevention is reported in documents, for example, chinese patent document CN 10639394B reports a method for preventing a thiophene conductive polymerized monomer from color change, specifically, an anti-color-changing agent is added into the thiophene conductive polymerized monomer as an anti-color-changing stabilizer, wherein the added anti-color-changing agent can prevent the thiophene conductive polymerized monomer from generating polymerization and oxidation during storage and transportation to cause color change, and the anti-color-changing agent is prepared by compounding methyl hydroquinone and diphenylamine, and the weight ratio of the compounded components is 6: 4; or the anti-discoloration agent is prepared by compounding methyl hydroquinone and nitrobenzene, and the mass ratio of the compounding is 7.5: 2.5.
however, few documents have been reported on the anti-discoloration agent for ketoximosilanes, and therefore, it is necessary to develop an anti-discoloration composition which can prevent discoloration of ketoximosilanes when added thereto.

Comparative example 3
The method for preventing discoloration of ketoximosilane was substantially the same as in example 2, except that aminopropyltriethoxysilane was not added to the mixture.
Comparative example 4
The method for preventing discoloration of ketoximosilanes is essentially the same as in example 2, except that the dimethyl dithiocarbamate is not added to the mixture.
Comparative example 5
The method for preventing discoloration of ketoximosilanes is essentially the same as in example 2, except that no amino silicone oil is added to the mixture.
Comparative example 6
The method for preventing discoloration of ketoximosilane was substantially the same as in example 2, except that hexamethyldisilazane was not added to the mixture.
Comparative example 7
The method for preventing discoloration of ketoximosilanes is essentially the same as in example 2, except that no quaternary ammonium salt of chitosan is added to the mixture.
Example 7
The storage stability of the ketoximino silanes in examples 1-6 and comparative examples 1-6 was tested according to the method specified in the national standard "general method for measuring chromaticity of chemical reagents-GB/T605-2006"), and the ketoximino silanes without any reagent were used as blank controls, and the specific method was as follows: the ketoxime silane is placed in a constant temperature environment of 60 ℃ under the sealing condition, the time from less than 30 blacks to 60 blacks is measured, and the results are shown in the following table 1:
TABLE 1 results of the ketoximosilane storage stability test
As can be seen from the results in the table, the ketoximosilanes of examples 1-6 and comparative examples 1-6 were added to one or more of the starting materials in the mixture as compared to the blank, and as a result, the ketoximosilanes were found to increase from less than 30 blacks to more than 60 blacks significantly more than the blank, indicating that the addition of one or more of the starting materials to the mixture of the present invention to the ketoximosilane significantly extended the storage time of the ketoximosilane;
further analyzing the data in examples 1-6 and comparative examples 1-2, it can be seen that the content of aminopropyltriethoxysilane and dimethyldithiocarbamate also significantly affects the storage time of ketoximosilane, and when the content of aminopropyltriethoxysilane is low and the content of dimethyldithiocarbamate is high (comparative example 1), the content of aminopropyltriethoxysilane is high and the content of dimethyldithiocarbamate is low (comparative example 2), the storage time of ketoximosilane is somewhat reduced because the active hydrogen in aminopropyltriethoxysilane reacts with free radicals, thereby reducing the oxidation rate of the product, whereas dimethyldithiocarbamate can convert hydroperoxide ROOH into a free radical-free, non-reactive and thermally stable product, and both work synergistically to maintain the system stable once the optimum ratio system is broken, the storage time of the ketoximosilane is reduced; analysis of the data in comparative examples 3-6 shows that the lack of any component can reduce the storage time of ketoximosilane, and the results show that the quality of ketoximosilane is greatly improved and the storage time of ketoximosilane is prolonged by the synergistic proportioning effect among the organic aminosilane, the peroxide decomposer, the amino silicone oil, the hexamethyldisilazane and the chitosan quaternary ammonium salt.
Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art will understand that: any person skilled in the art can modify or easily conceive the technical solutions described in the foregoing embodiments or equivalent substitutes for some technical features within the technical scope of the present disclosure; such modifications, changes or substitutions do not depart from the spirit and scope of the embodiments of the present invention, and they should be construed as being included therein.
