Antirust master batch and preparation process thereof

Abstract

The invention discloses an antirust master batch and a preparation process thereof. The antirust master batch is prepared from, by weight, 43-57 parts of carrier resin, 31-39 parts of an antirust agent and 12-18 parts of an assistant, wherein the carrier resin is prepared from, by weight, 100 parts of polypropylene, 7-20 parts of polyethylene, 2-15 parts of coumarone resin and 5-10 parts of modified polyurethane. According to the invention, through setting of the components and the proportions, processes and parameters of the components, the prepared antirust master batch has relatively high antirust performance, mechanical strength and mechanical property; the basic performance is provided for the prepared gas-phase antirust film; the tearing damage of the prepared gas-phase antirust filmis avoided; meanwhile, some raw materials do not need to be added for functional compensation, and the prepared antirust master batch further has certain viscosity and sealing performance, so that the prepared gas-phase antirust film can adsorb and get close to metal and metal products, the gaps between the gas-phase antirust film and the metal and metal products are reduced and dried, the effects of isolating air and preventing corrosion are achieved, and the gas-phase antirust master batch is suitable for wide application and popularization.

Description

technical field [0001] The invention relates to the field of metal antirust, in particular to an antirust masterbatch and a preparation process thereof. Background technique [0002] During transportation and storage, metal and metal products are often susceptible to corrosion from the atmosphere and other environments, causing surface corrosion, affecting the performance and appearance of metal and metal products, and even causing failure and scrapping of metal and metal products. and the damage of metal products, we use anti-rust packaging to protect metal and metal products, including gas-phase anti-rust packaging, which uses gas-phase corrosion inhibitors to continuously and slowly gasify at room temperature and volatilize corrosion-inhibiting gas to absorb On the bare metal surface, a stable protective film with a thickness of one to two molecules is formed, which can effectively prevent the corrosion of metal by ambient atmospheres such as oxygen and moisture. Due to t...

[0002] During transportation and storage, metal and metal products are often susceptible to corrosion from the atmosphere and other environments, causing surface corrosion, affecting the performance and appearance of metal and metal products, and even causing failure and scrapping of metal and metal products. and the damage of metal products, we use anti-rust packaging to protect metal and metal products, including gas-phase anti-rust packaging, which uses gas-phase corrosion inhibitors to continuously and slowly gasify at room temperature and volatilize corrosion-inhibiting gas to absorb On the bare metal surface, a stable protective film with a thickness of one to two molecules is formed, which can effectively prevent the corrosion of metal by ambient atmospheres such as oxygen and moisture. Due to the continuous volatilization of the gas phase corrosion inhibitor, it can achieve long-term, stable and excellent corrosion resistance. Anti-rust effect, the traditional anti-rust packaging materials are gas phase anti-rust paper and gas phase anti-rust film. The combination of polymer materials and vapor phase antirust masterbatch, including vapor phase antirust bag and vapor phase antirust stretch film, etc. Antirust masterbatch is the basic functional masterbatch for manufacturing vapor phase antirust film, and its main component is vapor phase corrosion inhibition agent and resin, but the existing anti-rust masterbatches generally do not have other properties except the gas phase anti-rust function.
