Description
Technical field
The invention belongs to field of waterproof materials, and in particular to a kind of high-weatherability waterproof roll and its preparation technology.
Background technology
The asphalt felt generally used in the current roof waterproof engineering in China, waterproof layer leakage (oozing) water phenomenon have turned into most prominent
The problem of going out.There is an urgent need to carry out the research and production of all kinds of high-quality waterproof materials, compared with traditional asphalt water-proof coiled material, gather
Vinyl chloride waterproof roll is easy for installation, and luminous reflectanc is strong, and resistant to chemical etching and weather resistance is excellent, and price economy is reasonable, because
This, since emerging, the application in roof water-proof field constantly rises, and has occupied quite a few market share at present.Though
Right PVC waterproof roll good market prospect, but manufacturer still faces further from client in promoting service
Ask, that is exactly more preferable product quality, longer service life and product duration of insurance limit.
Patent CN101962458A discloses a kind of PVC waterproof rolls and its preparation technology, the original of the PVC waterproof rolls
Boron mud or red soil are added in material as inserts, boron mud or red soil addition and PVC in the raw material of the PVC waterproof rolls
The mass percent of resin content is 40~50: 100, and the PVC waterproof rolls are using boron mud or red soil as inserts, significantly
Improve the stability in use and ageing-resistant performance of PVC waterproof rolls.The invention provides a kind of high-weatherability waterproof roll and
Its preparation technology, PVC is weakened as plasticizer as light stabilizer, dioctyl phthalate from Tinuvin XT 833
Interaction force between molecule, improve the resistance to low temperature of PVC waterproof rolls.Simultaneously using lead sulfate tribasic, disalt
Base lead stearate and dibasic lead phosphite these three stabilizers are used in combination, and can be produced synergy and complementary effect, be greatly improved
The stability of polymer, thermal degradations of the PVC during machine-shaping and use is prevented, ensure the durability of PVC waterproof rolls.
The content of the invention
It is an object of the invention to provide a kind of high-weatherability waterproof roll and its preparation technology, from Tinuvin XT
833 as light stabilizer, dioctyl phthalate weaken interaction force between PVC molecules as plasticizer, simultaneously
Using lead sulfate tribasic, dibasic lead stearate and dibasic lead phosphite, these three stabilizers are used in combination, and can be produced collaboration and be made
With and complementary effect, greatly improve the stability of polymer, ensure the durability of waterproof roll.
In order to achieve the above object, the technical solution adopted by the present invention is：A kind of high-weatherability waterproof roll, including it is following
Parts by weight material：
The preparation technology of this high-weatherability waterproof roll, step include：
1) raw material is weighed in proportion；
2) by Corvic and dioctyl phthalate, light stabilizer Tinuvin XT 833, tribasic sulfuric acid
Lead, dibasic lead stearate, dibasic lead phosphite, epoxidized soybean oil, precipitated calcium carbonate, stearic acid are in 90-95 DEG C of mixing
10min, discharging cooling are standby；
3) temperature is controlled at 120-140 DEG C, to melt rolling, clot, sheet material is cut after slice, is 120- in temperature
130 DEG C, pressure be 12-14Mpa under heat 5-10min, molded after natural cooling, take out sheet material；
4) the piece timber-used standard specimen cutter of extrusion is punched tensile sample.
Preferably, the Corvic is SG-3 types or SG-5 type Corvics.
The beneficial effects of the invention are as follows：
1. contain phenyl ring in plasticizer phthalic acid dioctyl ester (DOP) structure, with polyvinyl chloride resin after high-temperature mixing,
DOP molecules are inserted between PVC strands, DOP ester group dipole and PVC dipolar interaction, and make DOP phenyl ring pole
Change, and then DOP small molecules can be combined together well with PVC macromoleculars.Due to DOP nonpolar moieties methylene based structures simultaneously
Do not polarize, it is clipped between PVC strands, increases the distance between chlorine atom, weakens the interaction between PVC molecules
Power, the distance between PVC strands are expanded, the energy required for making the motion of PVC molecule segments reduces, that is, reducing
The glass transition temperature of polyvinyl chloride resin, and then improve the resistance to low temperature of PVC waterproof rolls.
Reacted 2. heat stabilizer main function is the HCl 1) with abjection, suppress autocatalysis；2) replace in PVC molecules not
Stable allyl chloride atom or tertiary carbon position chlorine atom, to suppress de- HCl reactions；3) addition occurs with the diene in PVC molecules
Reaction, conjugated structure is destroyed, improve stability；4) free radical is caught, prevents chain reaction.Tribasic sulfuric acid is used in the present invention
These three stabilizers of lead, dibasic lead stearate and dibasic lead phosphite are used in combination, and can produce synergy and complementary effect, greatly
The big stability for improving polymer, thermal degradations of the PVC during machine-shaping and use is prevented, ensures PVC waterproof rolls
Durability.
3. because PVC waterproof roll is long-term use of out of doors, the environment of solar irradiation, high temperature and peracid need to be subjected to
Test, Tinuvin XT 833 are used effectively to lift the weather resistance of coiled material as light stabilizer in of the invention.
