Description
Technical field：
The present invention relates to thermal insulation material technical fields, and in particular to a kind of fluid media (medium) conveying pipe insulation material.
Background technology：
By pipeline fluid media (medium) be in industrialized production generally in the way of, be conducive to improve transfer efficiency with
And fluid media (medium) is avoided to mix impurity in transmission process.And for high temperature or cryogen medium, in order to prevent in profit
Thermal loss is caused when with pipeline or is gone bad because temperature increases, and needs to carry out isothermal holding to pipeline.
Currently, cladding mode of the isothermal holding of pipeline frequently with thermal insulation material, although and steel sleeve steel insulating tube road is kept the temperature
Effect is good, but since the setting of outer layer pipe significantly increases the weight of pipeline, and there is also by environmental corrosion for outer layer pipe
The problem of.For this problem, we develop a kind of fluid media (medium) conveying pipe insulation material, by foamed aluminium and heat-preservation cotton
Pipe insulating layer is formed, protection shell of the foamed aluminium as heat-preservation cotton effectively extends making for heat-preservation cotton while mitigating weight
Use the service life.
Invention content：
Technical problem to be solved by the present invention lies in providing, a kind of heat insulation effect is good, light and fluid with long service life
Medium conveying pipe insulation material.
The technical problems to be solved by the invention are realized using technical solution below：
A kind of fluid media (medium) conveying pipe insulation material forms pipe insulating layer, the bubble by foamed aluminium and heat-preservation cotton
Foam aluminium ring is located at the outside of heat-preservation cotton around fitting, and the heat-preservation cotton is made of the raw material of following parts by weight：Asbestos wool 30-40
Part, 15-25 parts of sepiolite fibre powder, 20-30 parts of gelling agent, 5-10 parts of aluminium-magnesium silicate, 1-5 parts of microwax, polytetrafluoroethylene (PTFE) are super
1-5 parts of fine powder, 1-5 parts of hexamethylolmelamine pregnancy ether.
The preparation method of the heat-preservation cotton includes the following steps：
(1) asbestos wool and sepiolite fibre powder are mixed to be placed in 110-120 DEG C of baking oven and is dried to constant weight to get material
I；
(2) microwax is heated to molten condition insulated and stirred, and aluminium-magnesium silicate and superfine powder of polytetrafluoroethylene is added, stirred
It mixes uniformly to get material II；
(3) gelling agent is heated to 120-130 DEG C of insulated and stirred, adds material II and hexamethylolmelamine pregnancy
Ether stirs evenly, and material I is then added, and is again stirring for uniformly, and be cooled to 0-10 DEG C of guarantor with the cooling rate of 5-10 DEG C/min
Temperature stands 30min or more to get heat-preservation cotton.
The gelling agent is shunk by polyglutamic acid, cetanol, ethylene glycol dimethacrylate, trimethylolpropane tris
Glycerin ether is made, and preparation method is：Cetanol is first heated to molten condition insulated and stirred, adds dimethacrylate second
Diol ester continues to be heated to 120-130 DEG C of insulated and stirred, and polyglutamic acid and trimethylolpropane tris glycidol is then added
Ether stirs evenly at 120-130 DEG C, and is transferred in 0-10 DEG C of environment and is stood overnight to get gelling agent immediately.
The polyglutamic acid, cetanol, ethylene glycol dimethacrylate, trihydroxymethylpropanyltri diglycidyl ether
Mass ratio is 10-20:1-5:1-5:1-5.
The polyglutamic acid is selected from food-grade polyglutamic acid.
By filling-modified, method of modifying is the aluminium-magnesium silicate：First aluminium-magnesium silicate is placed in 110-120 DEG C of baking oven
It is dry to add methanol, and be heated to reflux state insulated and stirred 10min or more to constant weight, N- methylol propylene is then added
Amide, dimethyl itaconate and 3.5wt% persulfate aqueous solutions continue the insulated and stirred that flows back, to be polymerized to subtract after reaction
To recycle methanol, into condensate residue plus filter residue is washed in water stirring, filtering, is finally sent into filter residue and is freeze-dried for pressure concentration
In machine, micro mist is made to get modified magnesium aluminium silicate through micronizer in dry obtained solid.
The aluminium-magnesium silicate, N hydroxymethyl acrylamide, dimethyl itaconate, potassium peroxydisulfate mass ratio be 5-10:
0.5-3:0.5-3:0.05-0.1。
N hydroxymethyl acrylamide generates acrylic resin, the acrylic acid tree of generation with aggregated react of dimethyl itaconate
Fat incorporates in the hole of the unique three dimensions chain structure of aluminium-magnesium silicate immediately at reflux, cured rear and magnesium silicate
Aluminium combines together, to improve the heat-insulating property of aluminium-magnesium silicate.
The beneficial effects of the invention are as follows：
(1) present invention makes full use of property specific to foamed aluminium using foamed aluminium as the protection shell of heat-preservation cotton, with
Corrosion resistance, sound insulation and noise reduction and the absorption impact for improving made thermal insulation material, to extend the service life of heat-preservation cotton；
It is avoided simultaneously using the big drawback of weight existing for steel sleeve steel insulating tube road；
(2) present invention is aided with sepiolite fibre powder, gelling agent and other auxiliary agents and heat preservation is made using asbestos wool as major ingredient
Cotton, there is made heat-preservation cotton excellent heat-insulating property, thermal coefficient to be less than 0.025W/ (m.K), to suitable for fluid media (medium)
Pipe insulation conveys, and reduces the loss of long-distance sand transport process medium fluid medium heat.
