Description
Technical field
The invention belongs to novel modified asphalt field of material technology, and in particular to a kind of non-halogen flame-proof smoke-restraining pitch and its system
Preparation Method.
Background technology
Recent decades, with the fast development and the drastically expansion of urban population of China's economy, ecological environment problem is increasingly
Prominent, air quality drastically declines, and is increasingly becoming the bottleneck of puzzlement economic development.Therefore, 18 big Special attention will be given to coordinators with
Natural harmony develops, and core is to adhere to taking a new road to industrialization, and accelerates to greatly develop while Economic Growth Mode Transformation
Ecological benefits type economy, effort makes socio-economic development be adapted with resource, environmental bearing capacity.In April, 2014 is national first
Revision passes through《Law of Environmental Protection of the People's Republic of China》, environmental protection concept is included into law.Hereafter, Green Traffic Idea is progressively obtained
To attention, the theory wherein emphasizes low emission, low stain.
At present, the surface layer on most domestic road surface uses asphalt material, especially highway surface layer, seldom
Cement concrete material is selected on number road surfaces, and it is a series of not available for the road surfaces such as cement concrete that this is due to that bituminous paving has
Premium properties, such as bituminous paving have that surfacing seamless, noise are small, mechanized construction degree is higher, maintenance is convenient
The advantages of.But, overwhelming majority hot-mix asphalt mixture can produce substantial amounts of flue gas in mix and work progress at present, the cigarette
Gas has a strong impact on the health of workmen, and pollution is caused to environment.Wherein, the pollution sources are due to that asphalt binder is caused
's.In recent years, researcher expanded substantial amounts of research for these this problems, and achieved certain achievement, such as using temperature
Mix, cold-mix asphalt compound technology or fire retardant added into pitch, to reach the effect of energy-saving and emission-reduction.But, warm mix and cold
The technology of mixing can only be using the relatively low pitch of viscosity, therefore the durability to bituminous paving has adverse effect on, and the resistance used
It is generally inorganic hydroxide fire retardant or organic fire-retardant to fire agent, because fire retardant addition content is larger, although can play fire-retardant suppression
Cigarette is acted on, but its cost is higher, and most of fire retardants can not improve the traditional performance of pitch, and some can even be produced not
Profit influence.
The content of the invention
It is an object of the invention to provide a kind of non-halogen flame-proof smoke-restraining pitch and preparation method thereof, to overcome prior art
It is not enough.

Mixture A；
2) coupling agent and then into mixture A is added, mixture B is obtained after stirring；
3) and then by being filtered by vacuum and being washed to after mixture B natural coolings there is no bubble production in the liquid of extraction
Give birth to, ground after then drying and 200 mesh sieves excessively can be prepared by machine attapulgite；
4), pitch is heated to after molten condition to sequentially add machine concave convex rod under 1500-2500r/min mixing speed
Stone and dispersant, mixture C is obtained after then stirring；
5) defoamer, is added into mixture C and is stirred, you can non-halogen flame-proof smoke-restraining pitch is obtained.
8th, the preparation method of a kind of non-halogen flame-proof smoke-restraining pitch according to claim 7, it is characterised in that step 1)
With step 2) in to obtain mixture after 300~400r/m speed stirring 1.5-2.5h.
Further, step 4) in, pitch is heated to 150-170 DEG C to molten condition, then with 2000~3000r/
Min mixing speeds sequentially add machine attapulgite and dispersant, then improved at 150-170 DEG C mixing speed to 3000~
4000r/m simultaneously keeps 20~30min, obtains mixture C.

It can be obtained by table 1-3, with the increase of organic attapulgite stone volume, the oxygen index (OI) of compound system is significantly increased.Its
In, when organic attapulgite stone volume is 5%, the oxygen index (OI) of compound system reaches 27%, reaches fire retardant rank, significantly improves
The fire resistance of pitch and its concrete.In addition, the addition of organic attapulgite stone significantly improves the high-temperature behavior of pitch, and it is right
Cryogenic property slightly has improvement.
