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
The present invention relates to the rust-preventive agent field, exactly is a kind of preparation method of metal antirusting agent of the 1-of containing hydroxy benzo triazole.
Background technology
Water-based antirust agent is a kind of aqueous rustproof solution, can effectively protect the materials such as steel, iron, prevents from getting rusty.The difference that requires according to rust-proof life, and water the antirust time limit can reach several days to several months than mixing use by certain, if certain outer packaging condition is arranged, the antirust time can reach more than 1 year.The existing many rustless properties of rust-preventive agent are not good, are badly in need of a kind of metal antirusting agent of good antirust property.
Summary of the invention
The object of the present invention is to provide a kind of preparation method of the metal antirusting agent that contains dimethyl silicone oil of good antirust property.
Above-mentioned purpose realizes by following scheme:
A kind of preparation method who contains the metal antirusting agent of 1-hydroxy benzo triazole is characterized in that: may further comprise the steps:
(1) 5-8 weight part liquefied petrolatum, 2.2-4.4 weight part acetyl tributyl citrate three (2-ethylhexyl) ester, 3.5-5 parts by weight of acrylic acid, 4-6 weight part epoxy oleum lini, 2-3 weight part dimethylbenzene, 3-5 weight account polyethylene wax are added reactor, be warming up to 105-115 ℃, begin stirring and add 3-6 weight part urea, 0.2-0.3 weight part Potassium Persulphate, 0.3-0.5 weight part borax, 0.2-0.3 weight part zinc powder;
(2) then be warmed up to 180-195 ℃ with 50-60 ℃ of/hour speed;
(3) 1-2 hour stopped heating of reaction;
(4) will add by weight surplus stock and add reactor, after the mixing dissolving and get final product;
Described surplus stock is the component of following weight parts:
Polyisobutene 1.9-2.7,2-aminoethyl 17 alkenyl imidazoline 2.1-2.9, N-phenyl-2-naphthylamine 1.2-2.3,1-hydroxy benzo triazole 1.3-2.5, urotropine 1-2, zinc dialkyl dithiophosphate 0.5-1.2, Sodium dodecylbenzene sulfonate 0.9-1.4, dimethyl silicone oil 0.8-1.4, water 97-103.
Described a kind of preparation method who contains the metal antirusting agent of 1-hydroxy benzo triazole is characterized in that: described reactor is stainless steel cauldron.
Beneficial effect of the present invention is: the consistency of the present invention and each material is good, the antirust time is long, epoxy oleum lini no side effects, the present invention can reach 4-6 month the antirust time, and copper, aluminum there is preferably adaptability, when the present invention is can slowly-releasing antirust in the metallic surface film forming, thereby prolong the antirust time.
Embodiment
