Abstract
The invention relates to a high-creep-resistant shape memory pipeline material and a preparation method thereof. The pipeline material consists of 100 parts by weight of polybutene-based resin, 0.1-5 parts by weight of anti-aging agent, 0-15 parts by weight of dye, 0.01-5 parts by weight of initiator and 0.02-10 parts by weight of auxiliary initiator. The pipe material can be prepared by adopting a melt extrusion method, and the pipe after melt extrusion has good oil resistance, high-temperature creep resistance and shape memory function, and can be used for repairing long-distance non-excavation pipelines of cold and hot water pipes and oil delivery pipes.
Description
Technical Field
The invention relates to the field of new pipeline lining materials, in particular to a high-heat-creep-resistant pipeline lining material with a memory function and a preparation method thereof.
Background
Creep refers to the phenomenon in which a material slowly undergoes plastic deformation under stress as the loading time increases. The high temperature creep refers to the phenomenon that the material slowly generates plastic deformation along with the extension of loading time under the stress that the temperature T is more than or equal to (0.3-0.5) T (T is the melting point and the temperature is T) and is far lower than the yield strength. Most polymeric materials undergo large plastic deformations around (0.3-0.5) times the melting point temperature, severely affecting the dimensional stability of the article.
Chinese patent CN 105175859A, CN 108774377B discloses an inner liner material of a flexible composite pipe, wherein the inner liner material is a polymer-based material, and comprises high-density polyethylene, polyester thermoplastic polyurethane elastomer, ethylene-propylene ternary rubber and the like, has good sealing property, corrosion resistance and high barrier property, and can be used for preparing an inner liner of the flexible composite pipe.
Chinese patent CN 107987416A discloses a shape memory composite material, which comprises 100 parts of PVC resin, 3.0-20 parts of plasticizer, 1.0-5.0 parts of stabilizer, 1.0-3.0 parts of lubricant, 5.0-30 parts of filler and 1.0-15 parts of impact modifier, and the prepared material can recover the original shape at a specific temperature.
At present, no pipeline material has been reported to have high heat creep resistance and shape memory function. .
Disclosure of Invention
In order to solve the defects and the shortcomings of the prior art, the primary aim of the invention is to provide a pipeline material with high heat creep resistance and shape memory function, which can be applied in a high temperature environment of 90-100 ℃.
The invention also aims to provide a pipeline material with good oil resistance.
The invention relates to a shape memory pipeline material with high heat creep resistance and a preparation method thereof, and adopts the following technical scheme:
the pipeline material comprises the following components in parts by weight: 100 parts of polybutenyl resin, 0.1-5 parts of anti-aging agent, 0-15 parts of dye, 0-15 parts of filler, 0.01-5 parts of initiator and 0.02-10 parts of auxiliary initiator.
In the pipeline material, the polybutylene-based resin is high isotactic polybutylene-1 and alloy in a high isotactic polybutylene kettle, wherein the weight ratio of the high isotactic polybutylene-1 to the alloy in the high isotactic polybutylene kettle is 0-100:100-0, wherein the weight average molecular weight of the polybutenyl resin is 50-100 ten thousand.
