Embodiment 1

[0032] 19 parts of polyethylene glycol dimethacrylate oligomer, 22 parts of polyethylene glycol laurate, 1.9 parts of saccharin, 1.5 parts of N, N-dimethylaniline, 0.015 parts of EDTA sodium salt, 0.015 parts of naphthalene Put the quinone into the reaction kettle, and stir it for 1 hour at a speed of 300 rpm until it is completely dissolved. Add 32 parts of bisphenol A fumarate, and stir for 2 hours at 800 rpm until completely dissolved. Then add 7 parts of polytetrafluoroethylene powder, and stir for 30 minutes at a speed of 1000 rpm until the mixture is evenly dispersed. Then add 7 parts of polyethylene powder, 3 parts of titanium dioxide, and 1 part of epoxy resin, and stir for 300 minutes at a speed of 800 to 1000 rpm to disperse evenly. Then add 1.2 parts of cumene hydroperoxide, and stir at a speed of 1000 rpm for 30 minutes until the mixture is uniformly dispersed, and the temperature of the material is controlled below 50° C. during stirring. Add 2.5 parts and the s...

Abstract

The invention relates to a pasty anaerobic pipe thread sealant with good property of preventing the liquid separation in storage and a preparation method thereof. The sealant includes moderate polyethylene glycol dimethacrylate oligomer, amine type accelerator, saccharin, metal-chelator, stabilizer, plasticizer, heatproof reinforcing agent, lubricating stuffing, pigment, hydrophilic white carbon black, cationic surfactant and ethanol. The preparation method includes mixing and stirring the materials in a certain ratio and adding sequence by a technology. The anaerobic pipe thread sealant has stable property and has no separated liquid storing for 1 year at room temperature, and has no separated liquid storing for 14 days at 50 DEG C.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a paste sealant and a preparation method thereof. Background technique [0002] Paste anaerobic pipe thread sealant is a kind of anaerobic adhesive, generally composed of (meth)acrylate oligomers, plasticizers, fillers, heat-resistant additives, accelerators, co-accelerators, pigments, Thickener and other components are stirred and dispersed evenly. It is a paste-like liquid-solid mixture before use. When in use, it is applied between the pipe threads, and the pipe threads are screwed together to remove the air between the mating surfaces of the threads. The glue undergoes free radical polymerization and solidifies under the promotion of metal ions. The advantage of paste anaerobic pipe thread sealant is that it has certain viscosity and thixotropy, it is not easy to flow when used, and it has certain self-lubricating and instant sealing properties. [0003] Since the component...
