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 fungicide, and they are also used as additives in gas phase antirust technology There is no reference, especially no information about the gas-phase anti-rust masterbatch and its preparation method and application using non-toxic natural product phytic acid, organic carboxylic acid alcohol amine salt and organic amine borate as compound corrosion inhibitor. to report

Abstract

The invention discloses a phytic-acid type gas-phase antirust masterbatch, and a preparation method and application thereof. The antirust masterbatch comprises the following components by weight: 30 to 50% a compound antirust agent, 40 to 60% parts of carrier plastic and 10 to 20% parts of an additive, wherein the compound antirust agent is prepared by mixing sodium benzoate, phytic acid, triethanolamine borate and monoethaneamine benzoate according to a mass ratio of 1.0-1.5: 2.5-3.2: 2.0-3.0: 1.0-1.3, and the additive is prepared by mixing sodium silicate, silicon dioxide, octadecanamide and an antioxidant 1076 according to a mass ratio of 1.0-1.3: 5.0-6.5: 2.5-3.3: 0.8-1.1. According to the invention, a strong chelating agent--alkaline phytic acid is used as a gas-phase corrosion inhibitor; triethanolamine borate is used as the additive; and the compound antirust agent has good dispersion and antirust effects and certain polarity, can penetrate the carrier plastic and volatilize to the surface of wrapped metal so as to form a protective film to block erosion by external corrosion substances, and is also exempt from frost precipitation due to incompatibility with a carrier caused by excessively-strong polarity of the compound antirust agent.

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 phytic acid-type gas-phase 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 countr...
