Technical field
The present invention relates to fire-resistant isolated material technical field, be specifically related to a kind of inorganic isolation refractory material and preparation side thereof
Method.
Background technology
Fireproof cable obtains extensive purposes in fields such as Current commercial building, industrial plants, residential buildings, mainly uses
Use in fire-fighting emergent, can guarantee after fire occurs that electric power, control circuit are not short-circuited phenomenon, within a certain period of time for disappearing
Anti-rescue provides sound assurance；The fireproof cable commonly using at present all can rise rapidly in strong flame lower conductor temperature,
Terminating nearly external flame temperature, temperature raises can make terminal facilities irregular working very by causing voltage to decline too high voltage drop
To not working, serious impact can be brought to fire-extinguishing and lifesaving；In order to control the voltage drop of cable, general cable outer layer arrange every
Absciss layer, prevents the too fast rising of temperature, but to be organic material expensive for existing isolated material, and isolation is limited,
Easily lost efficacy under hot conditions.
Content of the invention
The present invention is directed to the drawbacks described above of prior art, a kind of inorganic isolation refractory material and preparation method thereof is provided.
For solving above-mentioned technical problem, the present invention provides a kind of inorganic isolation refractory material, including following component: aquation silicon
Acid calcium, calcium sulfate, mica powder, aluminium hydroxide, talcum powder, redispersable latex powder, glass dust, polycarboxylate water-reducer, hydroxypropyl
Methyl cellulose ether.
As preferably, each component and mass percent be: hydrated calcium silicate the 33%th, calcium sulfate the 5%th, mica powder the 30%th, hydroxide
Aluminium the 20%th, talcum powder the 5%th, redispersable latex powder the 3%th, glass dust the 2%th, polycarboxylate water-reducer the 1%th, hydroxypropyl methyl cellulose ether 1%.
As preferably, each component material is powder.
As preferably, each component material is adopted and is used water as blender, and water blender consumption is the 2% of material gross mass.
The preparation method of a kind of inorganic isolation refractory material, comprises the steps:
A, by hydrated calcium silicate, calcium sulfate, mica powder, aluminium hydroxide, talcum powder, redispersable latex powder, glass dust, poly-
Carboxylic acid water reducer, hydroxypropyl methyl cellulose ether, put into kneader and stir；
B, addition water are stirred into sticky shape；
C, extrusion equipment is utilized to be expressed into cable outer layer uniformly.
As preferably, in described step C, cable outer layer material thickness is 2mm.
As preferably, material outer layer non-woven fabrics tightly wraps and prevents from coming off.
As preferably, material preparation deposits 3 days after completing, and can use after material is hardening.
Copper strips fire lagging cable is used to test as a comparison, the electricity preparing the isolation refractory material prepared by invention
Cable and employing copper strips fire lagging cable carry out 1000 DEG C of flame test, the temperature within test cable.
Redispersable latex powder is water-soluble redispersible powder, is divided into copolymer, the acetic acid second of ethylene/vinyl acetate
Alkene/versatic acid ethylene copolymer, acrylic copolymers etc., redispersable latex powder has high cementitiousness and flexibility, preparation
The strength of materials is high and has certain flexibility.
Use polycarboxylic acids as water reducer, good with the compatibility of matrix material, Product Green environmental protection, nonflammable, volume is low,
Water-reducing rate is high, shrinks little.
Selecting hydroxypropyl methyl cellulose ether as binding agent, hydroxypropyl methyl cellulose ether is nonionic cellulose
Ether, have odorless tasteless, be dissolved in water, salt discharge, PH stability, water-retaining property, dimensional stability, excellent film forming, dispersiveness
With features such as caking property.
Compared with prior art, the invention has the beneficial effects as follows:
(1) ep-type material, effect on environment is little, and in material, matrix material uses inorganic mineral material, effect on environment
Little, and do not burn do not have gas produce asepsis environment-protecting；
(2) pyroconductivity is little, matrix material use inorganic material, pyroconductivity is less, in use if it occur that
Fire, cable can also work within the regular hour；
(3) low cost, the raw material major part price comparison that the present invention selects is low；
(4) isolation effect is good, and matrix material uses inorganic material, and high-temperature resistant result is good.
Detailed description of the invention
The component of material and mass percent are as follows: hydrated calcium silicate the 33%th, calcium sulfate the 5%th, mica powder the 30%th, aluminium hydroxide
20%th, talcum powder the 5%th, redispersable latex powder the 3%th, glass dust the 2%th, polycarboxylate water-reducer the 1%th, hydroxypropyl methyl cellulose ether 1%.
Material is adopted and is used water as blender, and water blender consumption is the 2% of material gross mass.
Material preparation method comprises the following steps:
A, by hydrated calcium silicate, calcium sulfate, mica powder, aluminium hydroxide, talcum powder, redispersable latex powder, glass dust, poly-
Carboxylic acid water reducer, hydroxypropyl methyl cellulose ether, put into kneader and stir；
B, addition water are stirred into sticky shape；
C, utilizing extrusion equipment to be expressed into cable outer layer uniformly, material thickness is 2mm, and outer layer non-woven fabrics tightly wraps and prevents
Come off；
After D, above-mentioned material preparation complete, deposit 3 days materials hardening after can use.
Use the cable of copper strips fire lagging and use material of the present invention as the cable of isolated material at 1000 DEG C
Carrying out contrast test, the temperature within test cable under flame, result of the test is as follows:
| Time (min) | Cable internal temperature (DEG C) of copper strips fire lagging | Material of the present invention is as cable internal temperature (DEG C) of isolated material |
| 30 | 400 | 100 |
| 60 | 500 | 150 |
