| titleOfInvention | Composition and manufacturing method of antistatic return wheel |
| abstract | The present invention relates to a method and composition for manufacturing a transport wheel that prevents static electricity, and aims to maximize the antistatic effect through dispersion of carbon nanotubes as well as increase physical properties of hardness, tensile strength, and tear strength . In the method for manufacturing a transport wheel for preventing static electricity according to the present invention, a free polymer, which is a mixture of polyol and isocyanate, is prepared and prepared, and an antistatic composition is prepared in which a solvent and an antistatic agent are mixed, and the free polymer and the A first step of preparing a curing agent for curing the antistatic composition as a raw material for a wheel for transport; a second step of preparing a raw material mixture by mixing the free polymer prepared in the first step, an antistatic composition, and a curing agent; a third step of injecting the raw material mixture mixed in the second step into a mold in which a hub of the conveying wheel is inserted and molding it, and then molding the conveying wheel through mold release; and a fourth step of cycle-aging the wheel molded article released from the mold in the third step at room temperature and in an oven, and the step of preparing and preparing an antistatic composition in the first step is 25 parts by weight of an antistatic agent based on 100 parts by weight of the solvent. It is prepared in an amount of ~35 parts by weight, and the antistatic agent is prepared by mixing 96.5 to 97% by weight of the catalyst and 3 to 3.5% by weight of the carbon nanotubes, but the solvent and the catalyst are prepared by preparing the same polyol as the polyol of the free polymer. The composition of the transport wheel for preventing static electricity according to the present invention is an antistatic agent in which the same solvent and antistatic agent as the free polymer and polyol are mixed with respect to 100 parts by weight of a free polymer that is a mixture of polyol (first polyol) and isocyanate. 45 to 53 parts by weight of the composition and 14 to 16 parts by weight of the curing agent are mixed, and the antistatic composition is made by mixing 25 to 35 parts by weight of an antistatic agent with respect to 100 parts by weight of the solvent (second polyol), and the antistatic agent is It consists of a mixture of 96.5 to 97 wt% of a catalyst (third polyol) and 3 to 3.5 wt% of carbon nanotubes. |
