[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a silicone grease applicator, particularly a silicone grease applicator used for grease application for heat dissipation and insulation of semiconductor elements such as transistors and thermistors and various heat media.

[0002]

[Prior art]

 Lubricating grease is used to lubricate and muffle gears in office automation equipment, and to reduce the resistance of bearings such as rotary controls and rotary switches. It is generated in semiconductor devices such as transistors and thermistors. In order to dissipate heat, heat radiation fins, chassis, and circuit boards are coated with heat radiation grease, or insulating heat radiation sheets are sandwiched between heat radiation grease and heat radiation sheets.

In this case, as a method of applying the grease to a predetermined place, a method of applying the grease with a spatula or a brush is known. However, the application thickness varies from person to person and variations in lubricity and heat dissipation are caused. However, there is a problem in that the lubricant may be attached to the hand or applied to a place other than a predetermined place. Therefore, in order to evenly apply grease to a predetermined place, a method is known in which the grease is thinly spread on the jig with a spatula and the grease is transferred to a predetermined place with a rubber stamp or the like. This wastes what remains in the jig, and this requires evenly leveling each time.

[0004]

[Problems to be solved by the device]

 For this, there is also known an applicator that performs a series of operations by an automatic machine to perform roll transfer, but this makes the machine expensive, it is difficult to handle a large number of small quantities, and the shape of the object to be coated is difficult. It has the drawback of being limited.

[0005]

[Means for Solving the Problems] The present invention relates to a silicone grease applicator which solves the above disadvantages and drawbacks, and it relates to a silicone grease plastic storage part, discharge part, roller part or ball part. It is characterized by being stored in a container consisting of.

That is, the present inventor has conducted various studies to develop a silicone grease applicator which is easy to handle and can easily apply grease to a predetermined place, and as a result, it is used for commercial stationery glue or the like. Store the silicone grease instead of the glue in the plastic storage part that is provided with the discharge part, the roller part or the ball part, and apply the silicone grease by rotating the roller part or the ball part. Therefore, the inventors have completed the present invention by finding that it is possible to easily apply silicone grease to a predetermined place without wasting soiling hands. This will be described in more detail below.

[0007]

[Action]

 The silicone grease applicator of the present invention is one in which silicone grease is stored in the storage portion of a roller-type or ball-type applicator of commercially available stationery glue. The plastic storage unit for storing the silicone grease may be any as long as it has a storage unit, a discharge unit, a roll unit or a ball unit.

The silicone grease used here is made into a paste by adding various thickening agents to the silicone oil as a base oil to thicken it, and adding additives as necessary. However, examples of this silicone oil include dimethyl silicone oil, methylphenyl silicone oil, long-chain alkylmethyl silicone oil, silicone oil containing fluorine in the molecule, and trifluoropropylmethyl silicone oil.

The thickeners added to the silicone oil include soap-based agents such as lithium soap and aluminum soap, fine powder silica, carbon black, viscous mineral powder, metal oxides, Teflon powder, and the like. Non-soap-based additives are exemplified, and examples of the additives include oiliness improvers, extreme pressure lubricants, antioxidants, rust preventives, fillers, colored pigments and tackifiers. In order to use this grease as a heat dissipation grease, fillers such as zinc oxide, silica, metal oxides such as alumina, boron nitride, nitrides such as aluminum nitride, graphite, and silicon carbide are added.

Next, the silicone grease applicator of the present invention will be described with reference to the accompanying drawings. FIG. 1 shows a vertical cross-sectional view of a silicone grease applicator as one example of the present invention. As shown in the drawing, this is a storage part 2 for storing silicone grease 1, a discharge part 3, and a discharge part 3. It is composed of a roller support 4, a roller 5, and a lid 6. The storage portion 2 is made of plastic in order to push the storage portion with a finger to supply the silicone grease 1 from the discharge port 3 to the roller 5, and examples of the plastic include polyethylene, polyvinyl chloride, and polypropylene. It should be noted that the roller 5 may be made of plastic, rubber, sponge, felt, or the like, but it is preferable that the surface of the roller 5 has irregularities or grooves.

To apply silicone grease to a predetermined position using the silicone grease applicator of the present invention, the roller is rotated by pressing the roller 5 to the side to which the roller 5 is applied and sliding it sideways. Silicone grease is sequentially sent from roller 3 and the silicone grease is applied to the application part. When not in use, if the lid 6 is covered and the roller 5 is placed upright, the silicone grease is always in contact with the discharge part, so that it can be used whenever necessary.

Further, the silicone grease applicator may be of a ball type as another example, as shown in FIG. 2, in order to apply the silicone grease to a fine portion. The roller portion 5 shown in FIG. 1 is composed of a steel ball and a spring. This has a storage portion 7 for storing the silicone grease 1, a discharge portion 8, a ball support portion 9, a spring 10, The storage portion 7 is made of plastic for the above-mentioned reasons. The ball 11 and the lid 12 may be made of steel balls, plastic balls, or rubber balls.

In order to apply silicone grease to a predetermined position using the ball type applicator shown in FIG. 2, the ball 11 is pressed against a portion to be applied, and the spring 10 is contracted so that the ball support 9 and the ball support 9 are pressed. If a gap is created between the silicone grease 1 and 11, the stored silicone grease 1 will be sent along with the rotation of the ball 11 and silicone grease will be applied to the application part. This is suitable for coating fine areas because it can be applied with a very limited width.

In order to stop the outflow of the silicone grease in this silicone grease applicator, the pressing of the roller or the ball may be released, which stops the outflow of the silicone grease. It should be noted that by repeating such an operation several times, the silicone grease 1 is sufficiently filled in the storage portions 2 and 7, so that it can be applied at any time, but when not in use, it is possible to cover the lids 6 and 12 at any time as needed. Can be used.

【Example】

 Next, examples of the present invention will be given. Example 1 The accommodating part 2 is made of soft vinyl chloride resin, and the roller part 5 is made of hard vinyl chloride resin. The glue accommodating part of the glue container as shown in FIG. 1 has a silicone grease KS64 for electric insulation seal [Shin-Etsu Chemical Co., Ltd.]. [Product name] was filled and silicone grease was applied. Then, when applying KS64 to the sliding part of the glass bell jar using an applicator, you can apply it without soiling your hands when applying it and put it in water to check for seal leaks. No leakage was found, and it was confirmed that this was useful as a grease applicator for seals.

Example 2 A silicone container was prepared by filling the paste container of the glue container as shown in FIG. 1 in which the container part 2 and the roller part 5 were made of polyethylene with a heat-dissipating silicone grease G746 (trade name of Shin-Etsu Chemical Co., Ltd.). I made a grease applicator. Next, from the silicone grease applicator thus made, TO-3P type Transister 2SD751 [trade name of Matsushita Electronics Industrial Co., Ltd.] was coated with heat-dissipating silicone grease and the thermal resistance value was measured. When this was compared with the heat-dissipating silicone grease G746 hand-painted, the results shown in Table 1 were obtained, and there was no difference in the characteristics of the heat-dissipating grease between them. It has been confirmed that this product is useful as a silicone grease applicator, as it allows grease to be applied easily and without wasting dirt on hands.
