Embodiment 1

[0025] Weigh each component of the following parts by weight:

[0026]

[0027]

[0028] The above combinations are mixed evenly to obtain the anaerobic adhesive of the present invention.

[0029] In the present embodiment, the treated grease from the oil collection box of the range hood is used as a plasticizer, insoluble saccharin is used as an accelerator, acetylphenylhydrazine, tetranaphthoquinone, tetrasodium EDTA, and hydroxyethylidene diphosphonic acid are used as a stabilizer, and isopropylidene diphosphonic acid is used as a stabilizer. Benzene hydroperoxide was used as an initiator and fumed silica as a viscosity modifier. The anaerobic adhesive prepared in this example is mainly used for thread locking.

[0030] Stable storage: Add the anaerobic adhesive prepared in Example 1 into a 10*75mm glass test tube, and measure its hardening time in the test tube in a constant temperature water bath at 82°C. The general anaerobic adhesive standard is >2 hours, and the...

[0032] Weigh each component of the following parts by weight:

[0033]

[0034] The above combinations are mixed evenly to obtain the anaerobic adhesive of the present invention.

[0035] In the present embodiment, the treated grease from the oil collection box of the range hood is used as a plasticizer, insoluble saccharin is used as an accelerator, acetophenhydrazine, tetranaphthoquinone, and disodium EDTA are used as a stabilizer, and cumene peroxidation is used as an initiator. Fumed silica is used as a viscosity modifier, and blue paste is used as a pigment to identify various anaerobic adhesives. The anaerobic adhesive prepared in this example is mainly used for thread locking.

[0036] Stable storage: Add the anaerobic adhesive prepared in Example 2 into a 10*75mm glass test tube, and measure its hardening time in the test tube in a constant temperature water bath at 82°C. The general anaerobic adhesive standard is >2 hours, and the sample in Example 3 is hardened ...

Embodiment 3

[0043] Weigh each component of the following parts by weight:

[0044]

[0045]

[0046] The above combinations are mixed evenly to obtain the anaerobic adhesive of the present invention.

[0047] In this embodiment, the treated frying oil is used as plasticizer, insoluble saccharin as accelerator, acetylphenylhydrazine, tetranaphthoquinone, tetrasodium EDTA, hydroxyethylidene diphosphonic acid as stabilizer, titanium dioxide, mica powder, polytetrafluoroethylene powder, polyethylene powder as a filler, cumene hydroperoxide as an initiator, and fumed silica as a viscosity regulator. The anaerobic adhesive prepared in this example is mainly used for thread sealing.

[0048]Stable storage: Add the anaerobic adhesive prepared in Example 3 into a 10*75mm glass test tube, and measure its hardening time in the test tube in a constant temperature water bath at 82°C. The general anaerobic adhesive standard is >2 hours, and the sample in Example 2 is hardened Time >3 hours. Th...

Abstract

The invention provides an anaerobic adhesive for screw thread locking or pipe thread sealing, and solves the problems of unsatisfactory effect and large toxicity existing in present anaerobic adhesives modified by DOP or DBP. The anaerobic adhesive for screw thread locking or pipe thread sealing comprises 30-80wt% of an acrylate monomer, 1-5wt% of an initiator, 1-4wt% of an accelerant, 0-2wt% of a stabilizer, 5-50wt% of a plasticizer, and 0-20wt% of a viscosity modifier, and the plasticizer is recovered animal and vegetable oil. The recovered animal and vegetable oil, especially food waste oil is processed to be used as the plasticizer of the anaerobic adhesive, so the cured strength is reduced to maintain the detachability, the shrinkage is reduced, and the sealing performance is guaranteed.

Description

technical field [0001] The invention relates to the technical field of non-mechanical anti-loosening and sealing of screw fasteners, in particular to an anaerobic adhesive used for thread locking or pipe thread sealing. Background technique [0002] Bolts or screws can be said to be ubiquitous as a fastener, but they are in danger of loosening due to shock, vibration and other reasons. For threaded fasteners, the engineering community has been working on two aspects. One is to improve its bearing capacity; the other is to prevent loosening. Before the advent of chemical locking and sealing technology, people have used a variety of anti-loosening design solutions, such as stop washers, cotter pins, thread interference or interference deformation, and spring washers and use of internal damping nuts. These mechanical methods are all based on increasing parts and improving machining accuracy, resulting in an increase in cost. Moreover, it is still impossible to fundamentally ...
