Description
Technical field
The present invention is to belong to Asphalt Pavement Fire safety using porous ceramic grain load composite nanometer flame retardant and method for coating
Technical field.
Background technique
Extensive concern of the fire safety of tunnel sheet pavement by domestic and foreign scholars.Currently, researcher mainly adopts
It takes and adds various different flame retardants, the method for smoke suppressant in bituminous pavement to reduce or delay tunnel fire hazard process bituminous pavement
The heat and poison gas of generation reduce bituminous pavement to the greatest extent and thermally decompose and participate in burning, and improve tunnel sheet pavement fire safety evaluating
Property.However, bituminous pavement flame-retarding means are mainly the more single fire retardant of direct addition component, cooperative flame retardant in pitch at present
Effect is poor, less on pitch or Asphalt Mixture Performance influence, fire retardant volume in order to reduce；In order to improve dispersibility
The biggish micron order fire retardant of partial size is mainly used, flame retardant effect is poor, and the asphalt after leading to admixture fire retardant is in height
It still can thermally decompose, burn under warm environment, generate big calorimetric and poison gas, it is difficult to meet bituminous pavement flame-retardancy requirements.
Haydite is to be formed by high-temperature roasting through extruding, is a kind of manufactured aggregate, due to being in honeycomb knot inside it
Structure, thus have the characteristics that lightweight, high-strength, thermal coefficient is low, water absorption rate is big, the cobble for being commonly used to replace in concrete and broken
Stone is a kind of material of good load fire retardant.Porous ceramic grain apparent porosity is higher, and haydite has a large amount of little particles to be attached to
Its surface, it is surface irregularity, coarse, be conducive to fire retardant absorption, on the other hand, the aperture of haydite is capable of providing a large amount of gold
Belong to ionic vacancies, there is quite high excess free energy, surface hydroxyl structure easy to form, is conducive to enhance fire-retardant in gathering materials
The flame retardant effect of agent.
But asphalt road is improved using porous ceramic grain load composite nanometer flame retardant and method for coating currently without proposition
The additive amount of fire retardant and fire-retardant, smoke suppressing effect in face.The present invention proposes to load composite nanometer flame retardant side using porous ceramic grain
Method, and porous ceramic grain is coated, replace part to gather materials for bituminous pavement, fixed composite nanometer flame retardant improves tunnel
Bituminous pavement fire retardant volume reduces influence of the fire retardant to bituminous pavement, promotes tunnel sheet pavement fire safety.
Summary of the invention
(1) technical problem
It is adopted it is an object of the present invention to provide a kind of using porous ceramic grain load composite nanometer flame retardant and method for coating, this method
Nanoscale composite flame-retardant agent load and coat it with haydite, is directly mixed to solve current bituminous pavement fire retardant
Add, the problem that volume is less, ingredient is single, easy to reunite, release is fast, fire-retardant and poor smoke suppressing effect, to reach preferably fire-retardant
Effect realizes the self-extinguishment of bituminous pavement.
(2) technical solution
In view of current bituminous pavement, there are fire retardants directly to add, volume is less, ingredient is single, easy to reunite, release is fast, resistance
The problem of combustion and smoke suppressing effect difference, the present invention load nanoscale composite flame-retardant agent and are selected suitable material using porous ceramic grain
Material coats it, and technical solution is as follows: porous ceramic grain is cleaned up first, it is dry, and porous ceramic grain is added in TiCl4 solution
Water-bath evaporation, it is dry, then haydite is cleaned with NaOH solution；Then, processed porous ceramic grain is immersed in containing nano combined
In the salting liquid of fire retardant ion, it is uniformly mixed；Then, ammonium hydroxide is added, continues to stir at room temperature, nanometer is multiple in the liquid phase
It closes fire retardant to be deposited in porous ceramic grain hole on surface, be calcined in Muffle furnace；Finally, uniformly coating load using epoxy resin
The porous ceramic grain of composite nanometer flame retardant particle forms clad.To improve fire retardant volume indirectly, reduces and reunite, delay
Rate of release, improves that bituminous pavement is fire-retardant, smoke suppressing effect.
(3) beneficial effect
It as China's urban construction scale develops, needs to build more and more vcehicular tunnels and Urban Underground Passage, needs
The more bituminous pavements of making are wanted to improve driving comfort and the safety on road surface, are provided for flame retardant type bituminous pavement wide
Popularization and application foreground.In order to make bituminous pavement that can also reach road surface special in tunnel while giving full play to own advantages
The requirement of environment, i.e. flame-retardancy requirements, when fire occurs in tunnel, bituminous pavement does not encourage fire.It is provided using the present invention
The method used level load composite nanometer flame retardant and is coated gathering materials using porous ceramic grain, can gather materials it is same in level
When load composite flame-retardant agent, to reach better flame retardant effect, and increase fire retardant stability, fire retardant delayed to discharge, from
And the flame retardant property of fire retardant is improved, so that fire retardant has matching fire retardant to play effect in each step that pitch burns
With realizing the self-extinguishment of bituminous pavement to play better flame retardant effect.Solve current fire retardant release process fire-retardant effect fastly
Fruit is poor, can only play fire retardation for some thermal decomposition stage of pitch, cannot thermally decompose overall process to pitch and efficiently be hindered
The problem of combustion.The patented technology provided according to the present invention, by industry-university-research linkage, actively with relevant enterprise cooperation, Neng Goukai
Pitch efficient flame-retarding agent with independent intellectual property rights is issued, is used in vcehicular tunnel and Urban Underground Passage bituminous pavement, it can
Tunnel and Urban Underground Passage fire safety are improved, to provide theoretical foundation using flame-retardant pitch road surface in large tunnel,
It lays a good foundation further to study, scientific value with higher；Meanwhile improving tunnel and Urban Underground Passage asphalt road
Face Long-Term Properties improve Asphalt Pavement Fire safety and durability, save operation cost, have preferable economic effect
Benefit.
