Abstract
The invention discloses a preparation method of iron oxide black for high temperature resistant asphalt. The method comprises the following steps of: (1) evenly mixing 1-2 parts of stannic oxide, 1-2 parts of tannin extract, 1-2 parts of polypropylene, 0.3-0.5 part of titanate coupling agent TMC-201, 5-8 parts of coumarone resin and 1-2 parts of zinc borate, and pelleting through a double screw extrusion machine, thereby obtaining a modifying agent for later use; (2) mixing 60-70 parts of iron oxide black, 3-6 parts of aluminum triphosphate, 1-2 parts of ferrocene, 1-2 parts of coconut oil fatty acid diethanolamide, 0.1-0.2 part of antioxidant 168 and proper amount of deionized water in the modifying agent, performing ball milling for 10-20 minutes after mixing well, taking out and drying, adding proper amount of water for pulping, milling the pulp by a colloid mill to realize that grain size is less than 50 micrometers, baking the pulp to dry, and milling the dried material into powder, thereby obtaining a finished product.
Description
Technical field
The present invention relates to iron oxide black field, is exactly the preparation method of iron oxide black for a kind of high temperature resistant pitch.
Background technology
Z 250, chemical formula Fe
3o
4.Another name iron oxide black, magnet, magnet are the magnetic black crystals of tool, therefore be called again martial ethiops.Iron oxide black is widely used, yet its performance index are limited, is badly in need of customization at the specific breed of all directions.
Tannin extract (tannin extract) is the Chemicals that made through flooding and the step processing such as concentrated by the plant material that is rich in tannin.Be generally brown color to brown, powdery or bulk.Be mainly used in the skin of tanning, in curriery, be called vegetable tanning agent.As beneficiation inhibitor, water treating agent for boilers, drilling mud diluent and metallic surface inhibitor, condensed tannin extracts is also made carpenter's glue stick in addition.
Summary of the invention
The object of the present invention is to provide the preparation method of iron oxide black for a kind of high temperature resistant pitch.
Above-mentioned purpose realizes by following scheme:
A preparation method for iron oxide black for high temperature resistant pitch, is characterized in that: comprise the following steps:
(1) 1-2 part tindioxide, 1-2 part tannin extract, 1-2 part polypropylene, 0.3-0.5 part titanate coupling agent TMC-201,5-8 part coumarone indene resin, 1-2 part zinc borate mix, and twin screw extruder granulation, obtains properties-correcting agent standby;
(2) in properties-correcting agent, sneak into 60-70 part iron oxide black, 3-6 part aluminium triphosphate, 1-2 part ferrocene, 1-2 part cocoanut fatty acid diethanolamide, 0.1-0.2 part irgasfos 168 and appropriate amount of deionized water, mix rear ball milling 10-20 minute, after taking out oven dry, add again appropriate water making beating, by colloidal mill defibrination to particle diameter, be less than 50 μ m again, slurries are dried, and abrasive dust is finished product.
The preparation method of iron oxide black for described a kind of high temperature resistant pitch, is characterized in that: twin screw extruder granulation step is controlled temperature 140-170 ℃.
Beneficial effect of the present invention is: the present invention first prepares properties-correcting agent, then to iron oxide black modification, makes to add flame retardant property of asphaltum of the present invention good, and resistance to elevated temperatures is excellent.Make the adding of properties-correcting agent the present invention more easily form the system of evenly melting altogether with pitch, there is the effect of the pavement performance of enhancing bituminous pavement, toughness and the resistance to elevated temperatures of raising pitch.
Embodiment
A preparation method for iron oxide black for high temperature resistant pitch, comprises the following steps:
(1) 1 part of (kg) tindioxide, 2 parts of tannin extracts, 1 part of polypropylene, 0.5 part of titanate coupling agent TMC-201,5 parts of coumarone indene resins, 1 part of zinc borate mix, and control 160 ℃ of temperature, and twin screw extruder granulation, obtains properties-correcting agent standby;
(2) in properties-correcting agent, sneak into 70 parts of iron oxide blacks, 3 parts of aluminium triphosphates, 2 parts, luxuriant iron, 1 part of cocoanut fatty acid diethanolamide, 0.2 part of irgasfos 168 and appropriate amount of deionized water, mix rear ball milling 10-20 minute, after taking out oven dry, add again appropriate water making beating, by colloidal mill defibrination to particle diameter, be less than 50 μ m again, slurries are dried, and abrasive dust is finished product.
The iron oxide black product performance analysis data that the present embodiment is produced is as following table:
| Project | Index | Detected result |
| The water solubles (%) | ≤1.0 | ?0.58 |
| 105 ℃ of volatile matters (%) | ≤1.0 | 0.59 |
| Oil number (%) | 15-25 | 20.4 |
| Tinctorial strength (%) | 95-105 | 96.6 |
| Resistance to 200 ℃/30min (△ E) | ≤1.0 | 0.69 |
