Abstract
The invention discloses an anaerobic adhesive and a preparation method thereof and relates to the technical field of fine chemical engineering. The anaerobic adhesive is prepared from the following components in parts by weight: 50-60 parts of triethylene glycol dimethacrylate, 1.5-2 parts of ethylenediamine tetraacetic acid, 2-3 parts of hydroquinone, 2-3 parts of benzoyl hydrazine, 0.5-1 part of methylene blue, 0.5-1 part of benzoyl hydrazine and 3-5 parts of tert-butyl hydroperoxide; the preparation method comprises the following steps: adding the triethylene glycol dimethacrylate to a reaction kettle, heating, adding the ethylenediamine tetraacetic acid, stirring, standing, filtering and shifting the obtained filtrate into the reaction kettle; heating, orderly adding the hydroquinone, the benzoyl hydrazine and the methylene blue, stirring evenly and cooling to a room temperature, and finally, adding the tert-butyl hydroperoxide and stirring. The anaerobic adhesive prepared by use of the method is relatively long in storage period and relatively short in solidification time.
Description
Technical field
The present invention relates to technical field of fine, especially a kind of Anaerobic adhesive and preparation method thereof.
Background technology
Anaerobic adhesive is called for short anaerobic glue, abroad also known as " anaerobism locking agent; Anaerobic adhesive is a kind of novel seal tackiness agent; can not solidify time it contacts with oxygen or air; once after isolated air; add the katalysis of metallic surface, at the very fast polymerizing curable of room temperature, firmly bonding and good sealing can be formed.Traditional Anaerobic adhesive is long for set time, and intensity is lower, and along with widely using of Anaerobic adhesive, the product pursuing more high-quality is the needs of prodution and development.
Summary of the invention
The object of this invention is to provide a kind of Anaerobic adhesive and preparation method thereof, this Anaerobic adhesive and preparation method thereof can solve the problem of Anaerobic adhesive length set time.
In order to solve the problem, the technical solution used in the present invention is: a kind of Anaerobic adhesive and preparation method thereof:
Following raw material is adopted to be made:
Triethylene glycolbismethyl-acrylate 50 parts ~ 60 parts;
Ethylenediamine tetraacetic acid (EDTA) 1.5 parts ~ 2 parts;
Resorcinol 2 parts ~ 3 parts;
Benzoyl hydrazine 2 parts ~ 3 parts;
Methylenum coeruleum 0.5 part ~ 1 part;
Tertbutyl peroxide 3 parts ~ 5 parts;
The preparation method of Anaerobic adhesive comprises the following steps:
A, the triethylene glycolbismethyl-acrylate of aforementioned proportion is added reactor, adjust the temperature to 65 DEG C ~ 80 DEG C, add ethylenediamine tetraacetic acid (EDTA), stir process 2.5 hours ~ 3 hours;
B, leave standstill 10 hours ~ 12 hours, filter, gained filtrate is proceeded to reactor;
C, be warming up to 40 DEG C ~ 45 DEG C, add Resorcinol, benzoyl hydrazine, methylenum coeruleum successively, stir, be cooled to room temperature;
D, add tertbutyl peroxide, stir process 1 hour ~ 2 hours.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:
1, the present invention is simple to operate, production efficiency is high;
2, the Anaerobic adhesive of the present invention's production is longer for storage period, and intensity is high, and adhesive effect is better, and set time is shorter.
