Embodiment Construction
[0013] A preparation method of a metal antirust agent containing dimethyl silicone oil, comprising the following steps:
[0014] (1) 5 parts by weight (kg) of liquefied paraffin, 4.4 parts by weight of acetyl citrate tris (2-ethylhexyl) ester, 5 parts by weight of acrylic acid, 4 parts by weight of epoxy soybean oil, 2.5 parts by weight of xylene, 5 parts by weight Add polyethylene wax in parts by weight to the reactor, heat up to 115°C, start stirring and add 5 parts by weight of urea, 0.2 parts by weight of potassium persulfate, 0.3 parts by weight of borax, and 0.2 parts by weight of zinc powder;
[0015] (2) Then heat up to 180°C at a rate of 52°C / hour;
[0016] (3) Stop heating after 1.3 hours of reaction;
[0017] (4) Add the remaining raw materials into the reaction kettle in parts by weight, mix and dissolve to obtain the product;
[0018] The remaining raw materials are the following components by weight: polyisobutene 2, ethanolamine benzoate 0.9, cyclohexylamine b...

The invention discloses a preparation method of a metal rust inhibitor containing dimethyl silicon oil. The preparation method comprises the following steps of: adding 4-6 parts of liquefied paraffin, 2.3-4.8 parts of acetyl tri(2-ethylhexyl)ester citrate, 4-6 parts of acrylic acid, 3-5 parts of epoxidized soybean oil, 2.5-3.5 parts of dimethylbenzene and 3-5 parts of polyethylene wax by weight to a reaction kettle, raising the temperature to 105-115 DEG C, starting stirring and adding 3-6 parts of urea, 0.2-0.3 part of potassium persulfate, 0.3-0.5 part of borax and 0.2-0.3 part of zinc powder by weight; and stopping heating after raising the temperature for a while, adding the surplus raw materials to the reaction kettle according to parts by weight, mixing the materials uniformly and dissolving the mixture, thus obtaining the metal rust inhibitor. The preparation method has the beneficial effects that the metal rust inhibitor has rust inhibiting time as long as 4-6 months, has better adaptability to copper and aluminium and can form films on the metal surfaces while carrying out slow release and rust inhibition, thus lengthening the rust inhibiting time.
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 dimethyl silicone oil. 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 above...
