Embodiment Construction

[0034] 1. Description of planetary ultrasonic assisted solid-liquid ball milling reactor:

[0035] 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.

[0036] Technical parameter setting of ultrasonic-assisted solid-liquid ball milling reactor:

[0037] (1) Planetary transmission mechanism: autobiography 18-168 r / min (turntable); revolution 70-670 r / min (ball mill tank).

[0038] (2) Ultrasonic frequency: 40KHz.

[0039](3) Ultrasonic power: 200W.

[0040] (4) Ultrasonic intensity: 1.13 W / cm 3 .

Abstract

The invention relates to a preparation method of organic titanium polyaspartic acid ester and application thereof in ocean heavy anticorrosive coatings, and belongs to the technical fields of preparation and application of novel materials. The preparation method comprises the following steps of firstly, under the catalyzing function of gamma-phase nanometer aluminum oxide, putting a mixture of titanium hydride powder, epoxy resin, nanometer dispersant, titanate coupling agent, silane coupling agent and solvent into a ball mill reaction tank, and performing ball milling reaction under ultrasonic conditions, so as to obtain an organic titanium precursor polymer TTP-II; performing addition reaction on 4,4'-diaminocyclohexyl methane and diethyl maleate under a non-oxygen condition, so as to obtain an intermediate product; performing synthetic reaction on the intermediate product and the organic titanium precursor polymer TPP-II, so as to obtain the organic titanium polyaspartic acid ester.The organic titanium polyaspartic acid ester can be used for preparing ocean heavy anticorrosive primers, intermediate paints and topcoats, and can meet the underwater test requirements; the chalkinggrade is lower than or equal to 1, and the discoloring grade is lower than or equal to 1.

Description

technical field [0001] The invention belongs to the technical field of preparation and application of new materials, and in particular relates to a new process of mechanochemically synthesizing titanium nanometer high molecular alloy polymer and its application technology. 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, 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 prov...
