Antirust master batches for various metals as well as preparation method and application of antirust master batches

Abstract

The invention discloses antirust master batches for various metals as well as a preparation method and application of the antirust master batches. The antirust master batches comprise the following components in percentage by mass: 30-50% of a compounded antirust agent, 40-60% of carrier plastic and 10-20% of an auxiliary agent, wherein the compounded antirust agent is prepared by mixing disodium sebacate, sodium molybdate and diglycolamide oleate borate according to a mass ratio of (1-1.3):(1.1-1.5):(2.2-3.2); and the auxiliary agent is prepared by mixing stearic acid amide, silicon dioxide, sucrose fatty acid ester and an antioxidant 1076 according to a mass ratio of (0.9-1.3):(4.8-6.5):(2.5-3.3):(0.8-1.1). The diglycolamide oleate borate is adopted as an additive and has a dispersion effect and an antirust effect, and the compounded antirust agent has certain polarity, can penetrate through the carrier plastic and volatilize to the surface of a packed metal to form a protective film so as to prevent corrosion of external corrosive substances, and cannot be incompatible with the carrier plastic to generate frost due to too strong polarity. The antirust master batches do not contain harmful ingredients, are environment-friendly and safe to use, and can achieve an antirust effect on various 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...

Problems solved by technology

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
