The present invention relates to a method for covering eyeglass frames with silicone rubber tubular moldings. Eyewear products come in a variety of designs, from those made for practicality to those oriented toward fashion, but many of these have ear flaps and pads made of metal, plastic, or metal parts. It is said to be covered with plastic, and even when plastic is used, it is mainly a hard plastic material such as acrylic resin, acetate resin, or vinyl chloride resin, so in any case, the feel and fit on the skin are poor. In addition to feeling pain in the skin, and in some cases causing skin damage or rash, there is also the problem that it becomes slippery due to sweat. On the other hand, in order to solve the above-mentioned problems, attempts have been made to construct the entire ear flap part and pad part with silicone rubber material, but since silicone rubber generally has high gas permeability,
Body fat and sweat come into contact with the frame through the rubber and can cause deterioration, especially if the frame is made of metal.Also, silicone rubber is relatively expensive and is not as durable as other plastics. It has the disadvantage that it is difficult to obtain a high gloss. Furthermore, it has been proposed to simply cover the ear flaps and pads of commercially available eyeglass frames with a silicone rubber material instead of constructing the entire ear flaps and pads with a silicone rubber material. No effective method has been found so far. The inventors of the present invention conducted studies aimed at solving the above-mentioned problems, and found that all of the parts of the eyeglass frame that come into contact with the human body (earmuffs and pads) were made of silicone rubber material. First, we noticed that it is effective to coat them with a silicone rubber material, and conducted further research on this coating method, leading to the completion of the present invention. That is, in the present invention, when covering the ear flap portion and/or pad portion of an eyeglass frame with a silicone rubber tubular molded product, the silicone rubber tubular molded product has an average composition formula R 1 a Y as a swelling agent. b SiO4-a-b/2 (wherein R 1 represents a hydrogen atom or a substituted or unsubstituted monovalent hydrocarbon group, Y represents a hydroxyl group or a hydrolyzable group, a represents 0<a≦4, b is 0≦
b≦4, but a+b is 0<a+b≦4)
Silane or siloxane and/or general formula (In the formula, R 2 represents a substituted or unsubstituted monovalent hydrocarbon group, Z represents a divalent hydrocarbon group or an imino group, and n is an integer from 0 to 10.) A method for covering eyeglass frames with a tubular molded product made of silicone rubber, which comprises: swelling the eyeglass frame, attaching it to the ear flap and/or pad of the eyeglass frame, and then allowing the swelling agent to evaporate and diffuse. It is related to. The method of the present invention will be explained in detail below. First, the swelling agent used in the present invention has an average composition formula: R 1 a Y b SiO4-ab/2...() (wherein R 1 is a hydrogen atom or a substituted or unsubstituted monovalent hydrocarbon group , Y represents a hydroxyl group or a hydrolyzable group. a is 0<a≦4, b is 0≦
b≦4, but a+b is 0<a+b≦4)
The silane or siloxane and/or the general formula (In the formula, R2 represents a substituted or unsubstituted monovalent hydrocarbon group, Z represents a divalent hydrocarbon group or an imino group, and n is an integer from 0 to 10.) In the above formula (), R 1 represents a hydrogen atom or a substituted or unsubstituted monovalent hydrocarbon group, and Y represents a hydroxyl group or a hydrolyzable group. Specifically, R 1 is an alkyl group such as a methyl group, an ethyl group, a propyl group, a butyl group, an aryl group such as a phenyl group, an alkenyl group such as a vinyl group or an allyl group, or one of the hydrogen atoms of these groups. Examples include groups in which moieties are substituted with halogen atoms, etc. Hydrolyzable groups represented by Y include alkoxy groups such as methoxy, ethoxy, and propoxy groups, acyloxy groups such as acetoxy, and amino groups. , an aminoxy group, a ketoxime group, an amide group, an alkenyloxy group, and the like. Furthermore, R 2 in the above formula () represents a substituted or unsubstituted monovalent hydrocarbon group, and Z represents a divalent hydrocarbon group or an imino group. The group represented by R 2 is exemplified by the same groups as R 1 above, and Z is an alkylene group such as a methylene group, ethylene group, or propylene group, an arylene group such as a phenylene group, or an arylene group such as a phenylene group. group, and an alkalylene group such as -C 6 H 4 .CH 2 .CH 2 -.

Examples include 1,3,5,7-tetrahydrodienecyclotetrasiloxane. Furthermore, as the organosilicon compound represented by the general formula () above, Examples include. In the method of the present invention, first, a silicone rubber coating molded article is coated with one or two compounds represented by the average compositional formula () or general formula () as described above.
The tubular molded article for coating is swollen to a desired size by contacting with a mixture consisting of at least one species.
In the present invention, there is no particular restriction on the composition of the molded product, and various conventionally known silicone rubbers may be used, such as heat-curing type, low-temperature curing type, room-temperature curing type, etc., as well as so-called one-component type and two-component type. Any of these may be used, and in addition to the organic groups of the diorganopolysiloxane that is the main ingredient, in addition to alkyl groups such as methyl, ethyl, and propyl groups, phenyl groups, 3-trifluoropropyl groups, and vinyl groups are introduced. It may be something. Further, there are no particular restrictions on the tubular body of the covering molded article, except that it is required to have a shape that approximately matches the shape of the attachment point of the eyeglass frame. but,
It is desirable that the size is slightly smaller than the shape of the attachment point, and the shape is preferably 1 mm or more smaller in terms of fitability after attachment is completed. On the other hand, methods for bringing the molded article into contact with the swelling agent as described above include, for example, immersing the coated tubular molded article in the swelling agent or placing it in a gaseous atmosphere of the swelling agent. This contact time is defined as the time required for the molded product to swell to the desired dimensions, but the specific time depends on the composition of the silicone rubber material that makes up the molded product, the wall thickness of the covering tubular molded product, and the swelling. It is necessary to select an appropriate time depending on the type of agent, etc. The method of the present invention involves swelling a silicone rubber covering tubular molded article as described above, attaching it to the ear flap and/or pad portion of an eyeglass frame, and then impregnating or The adhering swelling agent is evaporated and diffused, and various methods can be used for this evaporation and diffusion depending on the type of swelling agent and molded product. , a method using electric or mechanical equipment such as a plate heater or a vacuum dryer; after a part of the swelling agent is evaporated and evaporated at room temperature and pressure, the remaining part is evaporated using a heating dryer at 50 to 100℃. Examples include a method of removing a swelling agent. In the present invention, it is also possible to use the swelling agent as described above dissolved or dispersed in an appropriate organic solvent, but organic solvents are generally highly toxic, and moreover, they may be harmful to plastics used in eyeglass frames. It is necessary to use these with consideration in order to change the quality of the material. As explained above, according to the present invention, the plastic parts of eyeglass frames in which the parts that come into contact with the skin of the human body are made of plastic can be very easily covered with a silicone rubber tubular molded product without any deterioration in quality. It is possible to provide eyeglass frames with the appropriate elasticity of rubber, a unique texture not found in other materials, and extremely little discomfort on the skin and a remarkable sense of familiarity. Therefore, as mentioned above, the eyeglass frames obtained by the method of the present invention have extremely good feel and fit against the skin, and do not cause pain or damage to the skin, and do not cause skin irritation. This has the advantage of suppressing slippage caused by Next, examples of the present invention will be given. Example 1 A silicone rubber tubular body (type of silicone rubber,
KT120R (manufactured by Shin-Etsu Chemical Co., Ltd.) was immersed in the swelling agent shown in the same table for 24 hours and then taken out, and the tubular body swelled to the dimensions shown in the same table. Next, this swollen tubular body was left in a room at 20° C. for 3 hours to allow the swelling agent to evaporate and evaporate, resulting in shrinkage to the dimensions shown in the table below. As is clear from the results in Table 1, it can be seen that all the tubular bodies after the swelling agent was evaporated and diffused returned to the dimensions before being immersed in the swelling agent.

After adding and kneading, a tube with an inner diameter of 2.0 mm and an outer diameter of 3.0 mm was formed by extrusion molding at a vulcanization temperature of 400°C, and then secondary vulcanization was performed at 200°C for 1 hour to obtain a sample. Ta. Next, the sample obtained above was cut to a length of 5 cm, and when this sample was left in 1,1,1,3,3,3-hexamethyldisiloxane at room temperature for 24 hours, the sample had a length of 7.5 cm. , swelled to an inner diameter of 3.0 mm. This sample was then attached to the ear flap of an eyeglass frame and left at room temperature. After 10 minutes, the sample shrunk and was firmly attached to the eyeglass frame without any deterioration of the plastic of the eyeglass frame. The eyeglass frames fitted with silicone rubber molded products in this manner had excellent feel and fit, and exhibited excellent functionality without slipping even when sweaty. Example 3 After adding and kneading 0.8 parts of di-t-butyl peroxide to 100 parts of KE540U (trade name, manufactured by Shin-Etsu Chemical Co., Ltd.), this was charged into a mold and molded for 8 minutes at a temperature of 170°C, and then further heated to a temperature of 200°C. Secondary vulcanization was performed at ℃ for 4 hours to form a molded article for covering the pad of an eyeglass frame. Next, this molded product for covering the pad portion was swelled and contracted in the same manner as in Example 2, thereby making it possible to fix it to the pad portion of the eyeglass frame. The same effects as in Example 2 were observed in the eyeglass frame having the pad portion covered with silicone rubber.
