Nail-free sucker rubber mat and preparing method

Abstract

The invention relates to a nail-free sucker rubber mat. The nail-free sucker rubber mat is prepared from, by weight, 90-110 parts of nitrile rubber, 3-6 parts of zinc oxide, 1-2 parts of stearic acid, 1-2 parts of an anti-aging agent, 60-80 parts of carbon black, 15-22 parts of a plasticizer, 1-3 parts of an accelerator and 1-2 parts of sulfur. The nail-free sucker rubber mat can suck to a smooth surface without glue or nails, and the sucking force of the nail-free sucker rubber mat is obviously larger than that of common sucker products; in addition, damage to a wall is avoided, and the nail-free sucker rubber mat can be moved freely and is easy and convenient to mount and demount. The surface of the rubber mat is smooth without air bubbles, and thus air leakage from the edge is not likely to occur when vacuum is generated. Rubber is not likely to age or deform under long-time compression or stretching.

Description

technical field [0001] The invention relates to a rubber formula and a preparation method of a nail-free suction cup rubber pad. Background technique [0002] Rubber suction cup has the advantages of convenient installation, strong adsorption, free movement, recyclable use, no damage to the sucked workpiece, no pollution, etc. The magnetic block is used to hang small objects, which brings great convenience to people's life, and the large suction cup with handle can be used for glass handling. [0003] The principle of this rubber suction cup is mainly to use the vacuum negative pressure generated in the rubber cavity to suck the workpiece tightly. When using the [0004] The air in the suction cup can be extruded to form a certain vacuum environment in the rubber cavity. Since the external atmospheric pressure is greater than the pressure in the rubber cavity, the suction cup can be adsorbed on the workpiece under the action of the external atmospheric pressure. achieve...

Problems solved by technology

[0005] During the production and processing of existing rubber suction cups, there may be adverse problems caused by defects in design and manufacturing process,

[0006] However, some failures are caused during use, such as the adsorption force is not strong enough to effectively absorb objects within the allowable range, or the adsorption time is short and it is easy to fall off automatically due to aging and other problems.
