The present invention relates to a method for preparing a graphene-containing inorganic coating composition for coating non-ferrous metal objects and a graphene-containing inorganic coating composition prepared thereby, in which the inorganic coating composition contains liquid silica sol that emits far-infrared rays and powdery graphene that has very excellent thermal conductivity, and thus it emits far-infrared rays beneficial to the human body while having excellent durability and thermal conductivity. The method comprises: adding isopropyl alcohol as a solvent to liquid silica sol and a liquid sealant, followed by uniform stirring for 2-3 hours, thereby preparing a first liquid binder; adding powdery graphene, filler and pigment to the first liquid binder, followed by stirring for 8-10 hours, thereby preparing a second binder; and adding a predetermined amount of an adhesion-enhancing agent to the second binder, followed by aging at a temperature of 25 to 32 C. for 9 to 11 hours.

The present invention relates to a rubber modifier, a conjugated diene-based polymer including a functional group derived from the modifier, and a method for preparing a modified and conjugated diene-based polymer using the modifier. The modifier is used as the modifier of a conjugated diene-based polymer and combined with a conjugated diene-based polymer chain to easily introduce a functional group having affinity with a filler. Accordingly, a modified and conjugated diene-based polymer prepared using a compound of the rubber modifier may have excellent affinity with a filler, and as a result, molded articles (for example, tires) manufactured from a rubber composition including the polymer may have excellent tensile strength, abrasion resistance, and wet traction.

Provided is a coating composition capable of forming a coating film capable of maintaining excellent tack-free properties (releasability) for a long period of time on a plastic substrate or a rubber substrate, and particularly an elastic substrate made of rubber. The coating composition contains a rubber and an oil that is a liquid at 25? C., wherein the oil is dispersed at an average particle diameter of 50 ?m or less.

Disclosed are a method for manufacturing a dissolvable slip and a dissolvable slip manufactured by same. The manufacturing method sequentially comprises the following steps: (1) mixing an adhesive with solid particles and dissolvable particles; (2) coating the mixture prepared in step (1) on the surface of a slip body; and (3) curing the mixture coated in step (2). The dissolvable slip manufactured according to the manufacturing method not only has a stronger anchoring force with a wellbore inner wall, but also can adjust the dissolution rate of the slip after the completion of fracturing to enable the slip to degrade within a preset time. Further, the dissolvable slip has a better abrasion resistance, is suitable for various temperature conditions, and can still work normally in a concentrated acid or a concentrated alkali environment.
