Embodiment Construction

[0031] 1. Description of planetary ultrasonic assisted solid-liquid ball milling reactor:

[0032] Working principle: When it is necessary to apply ultrasonic waves, insert the plug of the ultrasonic generator into the socket of the energy converter, and at the same time turn on the switch on the ultrasonic generator, at this time the energy converter starts to work, and the ultrasonic waves can be input. Due to the strong penetrating ability of the ultrasonic wave, it can penetrate the stainless steel plate with a thickness of 2mm, and have physical and chemical effects on the materials in the ball mill tank.

[0033] Technical parameter setting of ultrasonic-assisted solid-liquid ball milling reactor:

[0034] (1) Planetary transmission mechanism: autobiography 18-168 r / min (turntable); revolution 70-670 r / min (ball mill tank).

[0035] (2) Ultrasonic frequency: 40KHz.

[0036] (3) Ultrasonic power: 200W.

[0037] (4) Ultrasonic intensity: 1.13 W / cm 3 .

Abstract

The invention discloses a preparation method of an organic titanium precursor polymer TPP-II and application of the organic titanium precursor polymer TPP-II in a special coating, and belongs to the technical field of preparation and application of new materials. Under the catalysis of gamma-phase nano-alumina, a mixture of hydrogenated titanium powder, epoxy resin, a nano-dispersant, a titanate coupling agent, a silane coupling agent and a solvent is placed in a ball-milling reaction tank for a ball milling reaction under ultrasonic conditions; under the coupling action of mechanical force and ultrasonic wave, not only is the micron-sized titanium hydride refined to the nanometer scale, but also the break-chain graft polymerization of a high-molecular polymer is induced; and the organic titanium precursor polymer TPP-II with a hydroxyl group structure is obtained by ring opening of epoxy groups. The organic titanium precursor polymer TPP-II can be used to prepare high-temperature environmentally acid-resistant corrosion protective coatings, such as primers and topcoats of a flue gas desulfurization system and heat exchanger equipment.

Description

technical field [0001] The invention belongs to the technical field of preparation and application of new materials. Background technique [0002] As we all know, titanium is a very active metal element with low density, high specific strength, good ductility, low thermal conductivity, good high and low temperature resistance, non-toxic and non-magnetic, wear-resistant and corrosion-resistant, and is widely used in military industry and aerospace. , navigation, civil and other manufacturing fields, and is known as the structural material for space and ocean. Titanium is arranged in the IV subgroup (titanium group) element system in the periodic table of chemical elements. Its atomic number is 22, atomic weight is 47.88, and its valence is +2, +3, +4. Therefore, under certain environmental conditions, its activity also provides it with a plurality of reaction tendencies. [0003] The standard electrode potential of titanium is very low (E=-1.63V), and the passivation potent...
