Description
Technical Field
The invention relates to an antirust agent, in particular to a compound gas-phase antirust agent and a preparation method and application thereof.
Background
Atmospheric corrosion is the most widespread corrosion, with losses that account for more than half of the total corrosion losses. In the traditional antirust packaging process using the antirust oil, because the residual grease on the surface of the metal needs to be removed by adopting organic solvents such as chlorofluorocarbon and the like before unsealing, the method is not only complicated, but also the chlorofluorocarbon can damage the atmospheric ozone layer of the earth, and the method is increasingly limited. The gas phase rust prevention technology has the characteristics of convenient use, cleanness and cleanness, and becomes an important direction for the development of the technology for preventing atmospheric corrosion. The vapor phase corrosion inhibitor, also called as a vapor phase rust inhibitor (VCI), is an anticorrosive chemical that can prevent corrosion of metals by adsorbing gas volatilized automatically at normal temperature on the surface of the metals.
A gas phase rust-proof plastic Film (VCIF) has been developed in recent years, and a gas phase rust-proof agent is added to the plastic Film in a certain manner to form an anticorrosive packaging material. The gas phase antirust plastic master batch is sold abroad, can be used for producing gas phase antirust plastic packaging bags, or can be directly injection-molded into gas phase antirust plastic packaging containers of various shapes, can simplify the packaging link, and can also exert the advantages of transparency, thermoplasticity, airtightness and the like of the plastic containers. However, because the plastic processing conditions are generally between 150 ℃ and 195 ℃, the stable temperature range of the common traditional gas phase rust inhibitor is mostly below 100 ℃, and the gas phase rust-proof effect of a few rust inhibitors with higher processing temperature is not ideal, the screening of the gas phase rust inhibitor with higher processing temperature and excellent gas phase rust-proof performance becomes one of the key technologies. On the other hand, most of gas phase rust-proof materials used at home and abroad contain toxic and harmful substances such as nitrite, and the popularization and application of gas phase rust-proof technology are severely restricted, so that many people are dedicated to the development of gas phase rust-proof agents without nitrite.
Chinese patent CN104311975B discloses lauric acid diethanolamide borate gas-phase antirust master batch, a preparation method and application thereof, and CN104761786A discloses a phytic acid type gas-phase antirust master batch formula. These rust inhibitors are mostly polar compounds, and the compatibility with plastic films is yet to be further improved.
The amino acid compound has the characteristics of rich raw material sources, low cost, no toxicity and good biodegradability, and has become a research hotspot of green antirust agents. Amino acids can be prepared by proteolysis, and the heteroatom such as S, N, O contained in amino acids can form coordination compounds with metal ions. The corrosion inhibition effect of different amino acids on different materials (carbon steel, copper and copper alloy, aluminum and aluminum alloy, magnesium alloy, lead, nickel, stainless steel, Pb-Sb-Se-As alloy, aluminum silicon carbide and the like) has been reported in many documents, but the amino acids are mainly applied to aqueous solution and are not involved in a gas-phase antirust plastic film because the amino acids belong to amphoteric compounds and have large molecular polarity, and the amino acids are precipitated from the plastic film after being stored for a period of time to cause poor appearance and reduced antirust performance of a plastic packaging film.
Disclosure of Invention
The invention aims to solve the problems and provide a compound gas-phase antirust agent, a preparation method and application thereof.
The purpose of the invention is realized by the following technical scheme:
a compound gas-phase antirust agent comprises the following components in percentage by mass:
further, the non-polar amino acid is selected from one or more of valine, leucine, isoleucine, proline, phenylalanine, tryptophan, or methionine.
Further, the organic dibasic acid salt is dibasic carboxylic acid ammonium salt or sodium salt with carbon atom more than or equal to 4, and is selected from one or more of succinic acid, adipic acid or sebacate.
Further, the benzoate salt is selected from ammonium or sodium salts of benzoic acid or tert-butylbenzoic acid.
A preparation method of a compound gas-phase antirust agent comprises the steps of uniformly mixing nonpolar amino acid, organic dibasic acid salt, benzotriazole and benzoate according to a ratio, and finely grinding and drying to obtain the product.
The plastic master batch containing the compound gas-phase antirust agent comprises the following components in percentage by mass:
30 to 40 percent of compound antirust agent
50-60% of carrier plastic
10-20% of auxiliary agent.
Further, the auxiliary agent is prepared by mixing gas-phase white carbon black, polyethylene wax and 2, 6-di-tert-butyl-p-cresol according to the mass ratio of 1:0.8: 0.1.
Further, the carrier plastic is high-pressure polyethylene with the melt index of 4-7g/10min, and the polyethylene wax is low-molecular-weight polyethylene wax with the molecular weight of 3000-10000.
The preparation method of the plastic master batch of the compound gas-phase antirust agent comprises the steps of kneading and mixing the compound antirust agent, carrier plastic and auxiliary agent, processing the mixture into VCI master batch, adopting a twin-screw extruder with contrarotation, and then preparing the mixture into granules through a cold casting mold to obtain the gas-phase antirust plastic master batch.
Fully mixing plastic master batches and high-pressure polyethylene particles, and preparing the plastic film by an air refining extrusion method at the temperature of 170-180 ℃ and the screw revolution of 80-85 r/min, wherein the mass fraction of the plastic master batches is 3-5%.
Compared with the prior art, the invention selects nonpolar amino acid through the polarity regulation of amino acid molecules, utilizes the good corrosion resistance of amino acid compounds, selects nonpolar amino acid and uses the fumed silica as a dispersion carrier, and improves the compatibility of amino acid antirust agents and plastic films by utilizing the characteristics of large specific surface area, strong surface adsorption force and good dispersion performance of the fumed silica, thereby improving the antirust capacity of the fumed rust-resistant plastic films. The amino acid contains amino and carboxyl simultaneously, can simultaneously generate electrostatic interaction with organic acid and benzotriazole, and effectively improve the interaction between the components of the formula of the antirust agent and the integral antirust effect. Meanwhile, the nonpolar amino acid contains nonpolar groups, so that the compatibility with polyolefin plastics is improved, and the antirust component is prevented from being separated out of the plastics, thereby improving the appearance and the long-term antirust effect of the gas-phase antirust plastics. The production technology of the amino acid gas-phase antirust plastic master batch provided by the invention has the advantages that the developed antirust plastic film has excellent antirust performance and good appearance quality. The components do not contain carcinogenic components such as nitrite and the like, and do not bring harm to human bodies and environment in the using process.
