Embodiment Construction

[0014] A preparation method of a metal antirust agent containing 1-hydroxybenzotriazole, comprising the following steps:

[0015] (1) 6.1 parts by weight (kg) of liquefied paraffin, 2.9 parts by weight of acetyl citrate tris (2-ethylhexyl) ester, 3.7 parts by weight of acrylic acid, 4.2 parts by weight of epoxy linseed oil, 2 parts by weight of xylene, 5 parts by weight Add polyethylene wax in parts by weight to the reactor, heat up to 110°C, start stirring and add 3.1 parts by weight of urea, 0.3 parts by weight of potassium persulfate, 0.5 parts by weight of borax, and 0.3 parts by weight of zinc powder;

[0016] (2) Then heat up to 195°C at a rate of 60°C / hour;

[0017] (3) Stop heating after 2 hours of reaction;

[0018] (4) Add the remaining raw materials into the reaction kettle in parts by weight, mix and dissolve to obtain the product;

[0019] Described remaining raw material is the component of following parts by weight:

[0020] Polyisobutene 2.2, 2-aminoethyl he...

Abstract

The invention discloses a preparation method of a metal antirust agent containing 1-hydroxybenzotriazol. The preparation method comprises the following steps: adding 5-8 parts by weight of liquefied paraffin, 2.2-4.4 parts by weight of tri(2-ethylhexyl)acetocitrate, 3.5-5 parts by weight of acrylic acid, 4-6 parts by weight of epoxy linseed oil, 2-3 parts by weight of xylene and 3-5 parts by weight of polyethylene wax to a reaction kettle, heating to 105-115DEG C, stirring, and adding 3-6 parts by weight of urea, 0.2-0.3 parts by weight of potassium persulphate, 0.3-0.5 parts by weight of borax and 0.2-0.3 parts by weight of zinc powder. The metal antirust agent has a good compatibility with a plurality of materials, and has a long antirust time, and the epoxy linseed oil has no toxic side effects, so the antirust time of the metal antirust agent can reach 4-6 months, and the metal antirust time has a good adaptability to copper and aluminum materials and can form a film on the metal surface when the sustained release rust prevention is simultaneously carried out, thereby the antirust time of the metal antirust agent is prolonged.

Description

technical field [0001] The invention relates to the field of antirust agents, in particular to a method for preparing a metal antirust agent containing 1-hydroxybenzotriazole. Background technique [0002] Water-based anti-rust agent is a water-based anti-rust solution, which can effectively protect steel, iron and other materials from rusting. According to different anti-rust period requirements, if it is mixed with water in a certain ratio, the anti-rust period can reach several days to several months. If there are certain external packaging conditions, the anti-rust time can reach more than one year. Most of the existing antirust agents have poor antirust performance, and there is an urgent need for a metal antirust agent with good antirust performance. Contents of the invention [0003] The object of the present invention is to provide a kind of preparation method of the metal antirust agent containing simethicone oil with good antirust performance. [0004] The abov...
