Description
Technical field
The invention belongs to field of waterproof materials, and in particular to a kind of fire-retardant ageing-resistant TPO waterproof rolls and its preparation technology.
Background technology
TPO waterproof rolls are a kind of new environment-friendly type macromolecule waterproof materials, and the past is over 20 years in American-European roofing with preventing
Incredible success is achieved in water industry.Just due to its excellent physical and mechanical property, reliable installation and warp
Long-term use of excellent performance confirmed is crossed, TPO waterproof rolls have been obtained for being widely recognized as.TPO is TPO, is
Using the polymer production technology of state-of-art, it is blended by polypropylene (PP), polyethylene (PE) and EP rubbers (EPR) anti-
Answer the polymer of gained.This material is not simple blend, but an equally distributed copolymerization continuous phase, there is a system
Arrange unique performance, such as higher elasticity, tensile strength and preferable thermal weld temperature range.TPO is former by carbon atom and hydrogen
Son is formed, and the influence to environment is minimum；There is pliability at low temperature；Possesses prolonged dimensional stability；In service stage
Random time point on all recyclable recycle；Random color can be tuned into, it is not only attractive in appearance, superficial white can also be utilized to reflect
Daylight, reach the effect of energy-conservation.
Patent CN104356459A discloses a kind of TPO waterproof rolls containing nano-meter flame retardantses and preparation method thereof, purpose
To solve metal hydroxides using " small size " effect of nano-meter flame retardantses to sacrifice the mechanical property of TPO waterproof rolls and add
Work performance improves the technical barrier of its fire resistance.The present invention formula have TPO, fire retardant, nano-meter flame retardantses, calcium carbonate,
Aging agent bag, pigment bag composition.The present invention has in less amount of flame-retardant agent with regard to that can significantly improve the fire-retardant of TPO waterproof rolls
Performance, but its ageing-resistant performance is not high.The invention provides a kind of fire-retardant ageing-resistant TPO waterproof rolls and its preparation technology,
Using two kinds of resin raw materials of TPO Resin As and TPO resin Bs, the limitation of single resin is improved, antioxidant 1010 can be effectively
Prevent thermal oxidative degradation of the polymeric material during long-term ageing, and a kind of efficient processing stabilizers, while also profit
With organo montmorillonite and compound flame retardant DBPE-Sb2O3It can reach the effect of cooperative flame retardant.
The content of the invention
It is an object of the invention to provide a kind of fire-retardant ageing-resistant TPO waterproof rolls and its preparation technology, using TPO resins
Two kinds of resin raw materials of A and TPO resin Bs, improve the limitation of single resin, and antioxidant 1010 can effectively prevent polymeric material
Expect the thermal oxidative degradation during long-term ageing, while also utilize organo montmorillonite and compound flame retardant DBPE-Sb2O3It is reachable
To the effect of cooperative flame retardant.
In order to achieve the above object, the technical solution adopted by the present invention is：A kind of fire-retardant ageing-resistant TPO waterproof rolls, bag
Include following parts by weight material：
Wherein, fire retardant DBPE-Sb2O3Middle DBPE and Sb2O3Weight ratio is 1:1-2.
The preparation technology of this fire-retardant ageing-resistant TPO waterproof rolls, step include：
1) raw material is weighed in proportion；
2) by dry TPO Resin As and TPO resin Bs raw material, antioxidant 1010, polypropylene, polyethylene, magnesium hydroxide, titanium
White powder, calcium carbonate, polyethylene, talcum powder, light stabilizer, montmorillonite and fire retardant DBPE-Sb2O3It is equal in high-speed mixer and mixing
It is even；
3) through double screw extruder melting extrusion at being 200-250 DEG C in temperature, water cooling, granulation, it is put into blast drier
Inside it is dried.Dried pellet is pressed into 1-2mm thick sheets.
Preferably, the calcium carbonate particle diameter is 1000-2000 mesh.
Preferably, the light stabilizer is UV-292.
The beneficial effects of the invention are as follows：
1.TPO battens are in burning, compound flame retardant DBPE-Sb2O3Inside can generate SbBr3, the gas such as HBr, they
All it is the big halogen gas of density ratio air, is wrapped in the surface of combustion front, can thus hinders to burn with starvation.It is another
Aspect, they can catch-H ,-the OH ,-CH that high activity is produced when TPO is heated in the gaseous state2The free radicals such as R, so as to reach
To fire-retardant purpose.
2. because the structure of organo montmorillonite is sheet, and interlayer contains organic chemical groups.TPO strand is inserted
Enter between lamellar structure, and chemical group is reacted, and forms stronger bonding interface layer, it is hindered significantly
The motion of TPO strands.In heated combustion, organo montmorillonite hinders TPO softening and melting process, has completely cut off the external world
Heat, it is incomplete to result in the decomposition of compound system within a certain period of time, hinders combustion process.In summary, organic illiteracy takes off
Soil and compound flame retardant DBPE-Sb2O3It can reach the effect of cooperative flame retardant.
3. antioxidant 1010 can effectively prevent thermal oxidative degradation of the polymeric material during long-term ageing, while
It is a kind of efficient processing stabilizers, discoloration-resistant of the polymeric material under the conditions of high temperature process can be improved.
