Abstract

The invention discloses a biodegradable aluminum alloy hot rolling liquid which comprises the following components in percentage by weight: 30-70% of dioctyl terephthalate; 20% to 60% of neopentyl polyol ester base oil; 0.2% to 1.5% of methyl benzotriazole; 1%-5% of mahogany petroleum sulfonate; 1%-5% of vegetable oleic acid; 1%-4% of ethoxylated fatty amine; 2%-5% of polyoxyethylene oleate; and 2%-5% of an anionic surfactant. The invention further discloses a preparation method of the biodegradable aluminum alloy hot rolling liquid. Compared with the prior art, DOTP (dioctyl terephthalate) in any proportion is used in the rolling liquid to replace mineral oil which is not easy to degrade, and the performance of the rolling liquid after replacement is kept unchanged and is even superior to that before replacement, so that the product is good in lubricity, easy to biodegrade, low-carbon and environment-friendly, and an emulsifier easy to biodegrade is used in the rolling liquid.

Description

technical field [0001] The invention belongs to the field of aluminum alloy hot rolling fluid, in particular to a biodegradable aluminum alloy hot rolling fluid and a preparation method thereof. Background technique [0002] Most of the aluminum alloy hot rolling fluid products on the market now use mineral oil-based base oil. The development and refining of mineral oil produces a high carbon footprint, and the degradation rate of mineral oil is less than 20%, which is not easy to bio Degradation, poor environmental protection, less source of mineral oil, non-renewable, poor lubricity and large consumption. In addition, the existing aluminum alloy hot rolling liquid contains harmful substances, which are very harmful to the environment and water bodies. In order to realize the low-carbon environmental protection of rolling liquid in the process of production and use, it is necessary to develop biodegradable rolling liquid products. Biodegradable rolling fluid: Under natura...
