Embodiment Construction

[0011] A preparation method of iron oxide black for high-temperature-resistant asphalt, comprising the following steps:

[0012] (1) Mix 1 part (kg) of tin dioxide, 2 parts of tannin extract, 1 part of polypropylene, 0.5 part of titanate coupling agent TMC-201, 5 parts of coumarone resin, and 1 part of zinc borate, and control the temperature 160°C, granulate with a twin-screw extruder to obtain the modifier for later use;

[0013] (2) Mix 70 parts of iron oxide black, 3 parts of aluminum tripolyphosphate, 2 parts of ferrocene, 1 part of coconut oil fatty acid diethanolamide, 0.2 parts of antioxidant 168 and appropriate amount of deionized water into the modifier, mix After uniformity, ball mill for 10-20 minutes, take it out and dry it, then add an appropriate amount of water to beat, and then pass colloid mill to refine the particle size to less than 50 μm, dry the slurry, and grind it to get the finished product.

[0014] The iron oxide black product performance analys...

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 [0001] The invention relates to the field of iron oxide black, in particular to a method for preparing iron oxide black for high-temperature-resistant asphalt. Background technique [0002] Ferric oxide, chemical formula Fe 3 o 4 . Also known as iron oxide black, magnet, magnet, it is a black crystal with magnetic properties, so it is also called magnetic iron oxide. Iron oxide black is widely used, but its performance indicators are limited, and there is an urgent need to customize special varieties in all directions. [0003] Tannin extract is a chemical product obtained by processing tannin-rich plant raw materials through water extraction and concentration. Usually tan to tan, powdery or lumpy. It is mainly used for tanning leather and is called vegetable tanning agent in the leather industry. In addition, it is also used as mineral processing inhibitor, boiler water treatment agent, drilling mud thinner and metal surface corrosion inhibitor, and co...
