Problems solved by technology

[0003] Since the medicinal foil product is delivered in a hard state, without annealing and degreasing process, it is required that the additives can meet the lubrication requirements of double-sheet foil rolling, and at the same time, the residue on the surface of the medicinal foil after rolling is extremely low. In order to ensure For rolling lubrication, additives generally improve the lubricating ability through chemical adsorption and high carbon chain composition. For example, C12-C16 saturated fatty alcohol and C12-C16 fatty acid methyl ester are used as the main additives. The wetting property is too strong, and at the same time, the C12-16 saturated fatty acid methyl ester has insufficient cleaning ability on the surface of the medicinal foil, resulting in a decrease in the peel strength and dyne value of the medicinal foil. At present, the dyne value of the medicinal foil in my country is required to be no less than 34. The strength requirement is not less than 8, and the existing technology generally has low dyne value and peel strength

Abstract

The invention discloses a medicament foil rolling additive composition. The composition consists of the following components by weight: (A) 0.04-2.0% of low-temperature antioxidant, (B) 80-95% of fatty acid methyl ester, (C) 0.06-1.0% of phosphide anti-wear agent, (D) 1-15% of polyhydric alcohol and (E) 0.04-2.0% of high-temperature antioxidant, wherein the component (C) phosphide anti-wear agent is one or more of triaryl phosphate, tricresyl phosphate and phosphate amine salt; the component (D) polyhydric alcohol is one or more of trimethylolpropane, pentaerythritol and diethylene glycol. By compounding the carbon chain fatty acid methyl ester, the phosphide anti-wear agent and the polyhydric alcohol, the chemical adsorption capability and the flow cleaning performance are enhanced, the surface residue of a medicament foil product is greatly reduced on the premise of ensuring the lubricating capability, and the dyne value and peeling strength of a medicament foil are effectively improved.

Description

technical field [0001] The present invention relates to a medicinal foil rolling additive composition. Background technique [0002] During the rolling process, it is necessary not only to meet the rolling lubrication requirements, but also to meet the purpose of degreasing the aluminum foil after rolling without annealing. The cleanliness of degreasing directly determines the dyne value and peel strength of the foil. [0003] Since the medicinal foil product is delivered in a hard state, without annealing and degreasing process, it is required that the additives can meet the lubrication requirements of double-sheet foil rolling, and at the same time, the residue on the surface of the medicinal foil after rolling is extremely low. In order to ensure For rolling lubrication, additives generally improve the lubricating ability through chemical adsorption and high carbon chain composition. For example, C12-C16 saturated fatty alcohol and C12-C16 fatty acid methyl ester are used ...
