-20 parts by weight, 3 to 40 parts by weight of fine resin particles, and 5 to 20 parts by weight of a polymer adhesive.

重量％以上配合した基油の影響が出て来る。The base oil used in the present invention contains the above-mentioned chain hydrocarbon synthetic oil in an amount of 80% by weight or more, and the content of the synthetic oil is 80% by weight.
If the amount is less than 20, the non-polar property of chain hydrocarbon synthetic oil that does not attack ABS resin etc. is weakened.
The influence of the base oil blended in a weight percent or more appears.

％を越えない範囲内において適宜配合してもよい。In addition to the above-mentioned chain hydrocarbon-based synthetic oil, the base oil used in the present invention includes other base oil components that have little effect on the resin, have slight polarity, and are easily adsorbed to the resin, such as aromatic hydrocarbons. Synthetic oils and/or diphenyl ethers substituted with chain hydrocarbon residues having 10 to 22 carbon atoms may be appropriately blended within a range not exceeding 20% by weight.
高級脂肪酸のリチウム塩としてはステアリン酸リチウム
および／または１２−ヒドロキシステアリン酸リチウム
が特に好適である。As the lithium salt of higher fatty acid, lithium stearate and/or lithium 12-hydroxystearate are particularly suitable.
高級脂肪酸のリチウム塩の配合量は上記の基油１００重
量部に対して５〜２０重量部、好ましくは５〜１５重量
部であり、５重量部以下の場合にはグリースが軟らかく
なり、剪断安定性が悪く軟化流出してしまう。The amount of lithium salt of higher fatty acid blended is 5 to 20 parts by weight, preferably 5 to 15 parts by weight, based on 100 parts by weight of the above base oil. If the amount is 5 parts by weight or less, the grease becomes soft and shear stability is reduced. It has poor properties and tends to soften and leak out.
また、２０重量部以上になると、グリースが硬くなり塗
布性や粘着性が低下する。Moreover, if the amount exceeds 20 parts by weight, the grease becomes hard and its applicability and adhesiveness decrease.

~9n. 1 Prelion Liaoyuanqing Jing ζ / 1% 6bis Crush Resistance: Good resin fine particles, and is a component mainly blended to prevent grease from running out and to reduce frictional resistance during sliding.

球が特に好ましい。As resin particles, nylon 12 spheres, ultra-high molecular weight Ole 7
Commercially available products such as inpolymer spheres and functional phenol resin spheres are exemplified, but nylon 12 spheres and ole7 inbolymer spheres are particularly preferred.
このような樹脂微粒子の配合量は、上記の基油１００重

すので好ましくない。The blending amount of such resin particles is 3 to 40 parts by weight per 100 parts by weight of the base oil. If the amount is less than 3 parts by weight, it is difficult to obtain the initial effect, and if it is 40 parts by weight or more, it is difficult to obtain the initial effect. If this happens, the oil content will decrease and the tackiness of the grease will disappear, which is undesirable.

さらに低減させることができる。A part of the above resin fine particles may be optionally added to an amino acid-based functional powder, such as N1-lacroyl-lysine, N-
By substituting lauryl β-laur aspartate or the like, the friction and wear on the sliding surface can be further reduced.

に増加しない。The blending amount of the amino acid-based functional powder is 0.2 to 2% soy sauce. II: It is difficult to obtain the effect of adding moisture to the 98% yen or less, and the effect does not particularly increase even when the amount exceeds 2% by weight.
高分子粘着剤としては液状ポリイソブチレンおよび／ま

高分子粘着剤の配合量は、上記の基油１００重量部に対

所要の粘着性が少くなりまた、前記の粘着剤は低温で高
粘度となるため２０重量部以上になると、これを配合し
たグリースの低温（３０゜Ｃ）での操作トルクが上昇し
、このグリースを塗布したスイッチの操作性が悪くなる
。The blending amount of the polymer adhesive is 5 to 20 parts by weight per 100 parts by weight of the above base oil, and if it is 5 parts by weight or less,
The required tackiness decreases, and since the above-mentioned adhesive has a high viscosity at low temperatures, if it exceeds 20 parts by weight, the operating torque of the grease blended with it at low temperatures (30°C) will increase, causing the grease to become more viscous. The operability of switches coated with the coating becomes poor.

化防止剤、ジフェニルアミン系酸化防止剤）、銅板腐食

In addition to salt, a gap on the order of microns is formed on the surface to be coated, and an oil component is retained in the gap to prevent the grease from running out.It also maintains the thickness of the oil film, increases adhesion, and improves adhesive strength during sliding. Contains fine resin particles that reduce frictional resistance, so when the grease composition is applied to a resin sliding surface, the resin will not be attacked and the grease will have excellent adsorption and repeatability. It provides not only sliding durability but also a smooth operating feel.
