Multi-metal anti-rusting master batch as well as preparation method and application thereof

Abstract

The invention discloses multi-metal anti-rusting master batch as well as a preparation method and application thereof. The anti-rusting master batch comprises the following components in percentage by mass: 30-50% of a compounded anti-rusting agent, 40-60% of carrier plastic and 10-20% of an additive, wherein the compounded anti-rusting agent is prepared by mixing sodium benzoate, sebacic acid, triethanolamine boric acid ester and benzotriazole in a mass ratio of (1-1.3):(1.1-1.5):(2.2-3.2):(0.8-1.2); the additive is prepared by mixing stearic acid amino, coarse whiting, sucrose fatty acid ester and an antioxidant 1076 in a mass ratio of (0.9-1.3):(4.8-6.5):(2.5-3.3):(0.8-1.1). When being used as an additive, the triethanolamine boric acid ester has both a dispersion function and an anti-rusting function, the compounded anti-rusting agent has certain polarity and can penetrate the carrier plastic to be volatilized to the surface of packaged metal to form a protecting film, so that corrosion of external corrosive substances is prevented, and the phenomenon that frost separation is generated as the compounded anti-rusting agent is not compatible with the carrier plastic because of the too high polarity is avoided. The multi-metal anti-rusting master batch is free of harmful component, is environment-friendly and safe to use, and has the anti-rusting function on multiple metals.

Description

Technical field: [0001] The invention relates to the field of non-toxic gas-phase anti-rust plastic products suitable for various metal products, and specifically refers to a multi-metal anti-rust masterbatch, its preparation method and specific application. Background technique: [0002] Metal corrosion is a common problem involving various fields of the national economy. It is an electrochemical process in which oxygen and water act on the metal surface to form a mixture of oxides and hydroxides. It has great harm to the performance and value of metals and their products. Serious Sometimes it will cause a major accident and cause the equipment to be scrapped. During the production, transportation and storage of metal and its products, especially in the process of sea transportation and high-heat and humid land transportation, it will inevitably encounter corrosion and rust. According to statistics, in 2005, the economic loss caused by corrosion in my country was more than...

But for now, as an ideal green additive, borate is mainly used in the field of water-based cutting fluid (Li Wei, Ma Tao, Wang Sen, Tan Hailin. Application of borate in water-based cutting fluid .Tool Technology, 2010, 44(5): 93-95.), respectively play the role of extreme pressure lubricant, surfactant, antirust agent, anticorrosion and bactericide, and they are also used as additives in gas phase antirust technology There is no reference, especially there is no report on the gas-phase anti-rust masterbatch and its preparation method and application using non-toxic inorganic salts and organic amine borates as compound corrosion inhibitors
