Abstract
The invention discloses a rapid condensation high-strength flame retardant thermal insulation material and a preparation method thereof. The rapid condensation high-strength flame retardant thermal insulation material is prepared from the following raw materials in percentage by weight: 5-55% of metallic oxide, 5-55% of phosphate, 1-10% of additive, 0.5-5% of fiber material, 0.5-50 of thermal insulation component and 5-50% of water. The rapid condensation high-strength flame retardant thermal insulation material is high in condensation speed; when the material is placed for 4 hours at a normal temperature, the compression strength of the thermal insulation material can reach 20MPa, and the breaking strength can reach 3.5MPa; and when the material is placed for 8 days at a normal temperature, the compression strength of the thermal insulation material can reach 60MPa, and the breaking strength can reach 10MPa. The thermal insulation material has good compatibility with concrete, cement and the like and high cold resistance and can be used under low temperature conditions of 0-10 DEG C. The rapid condensation high-strength flame retardant thermal insulation material can be directly sprayed to walls, roadway walls, tunnel walls and the like or is poured into a grinding tool with appointed size and shape and is compacted and shaped by vibration.
Description
Technical field
The present invention relates to building material field, be specifically related to a kind of rapid coagulation high-strength fire-retarding lagging material and preparation method thereof.
Background technology
At present, mainly there is following shortcoming in the cement and polystyrene particle lagging material that conventional construction wall, coal mine roadway, tunnel are conventional:
1, take cement as sizing agent, cohesive force is weak, and with the poor adhesive force in body of wall, coal mine roadway, tunnel etc., poor durability, easily comes off.
2, the ultimate compression strength of lagging material, folding strength are low, be subject to shearing force, pressure effect easily broken, come off.
3, cost is high.Because lagging material self-strength is low, need at construction wall, coal mine roadway, to smear polymers anti-cracking mortar between tunnel and lagging material, every square meter increases the tens of unit of cost.
4, working procedure complexity, long construction period, curing cycle are long.Generally need 4-7 procedure, and per pass inter process needs interval just can complete for several days, long construction period.And owing to adopting cement to be sizing agent, conventional curing cycle need reach more than 28 days.
5, hollowing, crackle is easily caused.Sizing agent is done, easy to crack, easy hollowing with cement.
Summary of the invention
The object of the present invention is to provide a kind of rapid coagulation, high-strength, fire-retardant, good heat-insulation effect, lagging material and preparation method thereof easily of constructing.Technical problems such as which solving intensity difference in background technology, cohesive force is weak, working procedure is complicated, long construction period, curing cycle are long.
For reaching above-mentioned purpose, the concrete scheme that the present invention adopts is:
Rapid coagulation, high-strength, flame-retardant thermal insulation material are made up of the raw material of following weight percents: metal oxide, one or more in aluminum oxide, magnesium oxide, ferric oxide, zinc oxide, and total content is 5-55%; Phosphoric acid salt, one or more in dipotassium hydrogen phosphate, potassium primary phosphate, Secondary ammonium phosphate, primary ammonium phosphate, potassiumphosphate, ammonium phosphate, total content is 5-55%; Auxiliary agent, flyash, Sodium Tetraborate, trisodium phosphate, Sodium Silicofluoride, total content is 1-10%; Filamentary material, one or more in cotton fibre, glass fibre, bamboo fibers, carbon fiber, ceramic fiber, total content is 0.5-5%; Heat insulation component: one or more in glass microballon, cenosphere, urethane, asbestos, rock wool, eps foam, XPS foam, EPP foam, aerogel, total content is 0.5-50%; Surplus is water.

(1) by formula rate by metal oxide, phosphoric acid salt, auxiliary agent, filamentary material, water, be uniformly mixed 3-5min.
(2) mixture (1) obtained and heat insulation component are uniformly mixed 1-2min by formula rate.
Beneficial effect of the present invention:
Rapid coagulation of the present invention, high-strength, flame-retardant thermal insulation material have following characteristic:
1, preparation process is without the need to sintering, energy-saving and environmental protection.
2, material rapid coagulation, time of coagulation can scope regulation and control in 10 seconds to 30 minutes.
3, normal temperature lower 4 hours ultimate compression strength can reach 20MPa; Folding strength can reach 3.5MPa.
4, normal temperature lower 8 days ultimate compression strength can reach 60MPa; Folding strength can reach 10MPa.
5, good with the consistency such as concrete, cement.
6, high winter resistance, can use under-10 DEG C of cold condition.
7, thermal conductivity is 0.084-0.23W/mK.
8, namely material sprays namely shaping.
This rapid coagulation, form of construction work that is high-strength, flame-retardant thermal insulation material have two kinds, are respectively:
1, by this lagging material direct spraying to body of wall, wall, tunnel wall etc.
2, this lagging material is poured into the grinding tool of specifying size shape, jolt ramming is shaping.
