Embodiment 1

[0044] 1. Synthesis of nano-organotitanium polyaspartate (T-PAEs-A)

[0045] Step 1: Weigh 500g of 4,4'-diaminocyclohexylmethane (PACM≥98%), add it to a synthesis device with mechanical stirring, and fill it with N 2Evacuate the air, then raise the temperature to 60°C, control the temperature, slowly add 610g DEF (diethyl maleate) dropwise with a titration funnel, after the drop, raise the temperature from 60°C to 80°C, stop heating, and carry out Michael addition reaction. The whole reaction process was kept at a constant temperature of 80°C for 20 hours. Obtain the intermediate product PAE-1a for subsequent use;

[0046] Step 2: Prepare nano-organic titanium precursor oligomer (HTH) according to the method published in the invention patent ZL200810029936.1 "Nano-organic titanium polymer and its coating and manufacturing method", and add 850g of it to PAE-1a by weighing in excess , heated to 100-120° C. for 2 hours, cooled to room temperature, and the product T-PAEs-A (that...

Embodiment 2

[0048] Synthesis of aliphatic nano-organotitanium polyaspartate (T-PAEs-B):

[0049] The method is the same as T-PAEs-A, except that PACM is replaced by Laromin-C260 with the same quality, and other conditions are the same.

[0050] T-PAEs / A and T-PAEs / B are collectively referred to as aliphatic nano-organotitanium polyaspartate.

Embodiment 3

[0052] A preparation method of nano organic titanium marine heavy-duty anti-corrosion coatings, including the preparation of component A and the preparation of component B; wherein, the preparation of component A includes the preparation of primer, the preparation of intermediate paint and the preparation of topcoat The preparation of the B component also includes the preparation of the primer, the preparation of the intermediate paint and the preparation of the topcoat; the specific steps are as follows:

[0053] 1) The preparation of the primer of component A: Weigh 30 parts of aliphatic nano-organic titanium polyaspartate, 15 parts of 128 epoxy resin, 8 parts of liquid nitrile rubber, BYK-wetting and dispersing agent according to parts by mass 0.5 parts, 1.5 parts of liquid anti-sedimentation agent, 0.5 parts of BYK-defoamer, 0.5 parts of BYK leveling agent, 1 part of silane coupling agent, 15 parts of zinc phosphochromate, placed in a high-speed dispersing machine to disper...

Abstract

The inventon relates to a method for synthesizing an aliphatic nano organic titanium polyaspartic acid ester and paints thereof, comprising the following steps of: (1) aliphatic primary amine PACM (or LAROMIN C260) and DEF (diethyl maleate) perform Michael addition reaction to obtain a reaction product A (or B); and (2) the product A (or B) and nano organic titanium precursor oligopolymer (HTH) performs addition reaction to synthesize the aliphatic nano organic titanium polyaspartic acid ester (T-PAEs). Using as a matrix and compounded with a relative auxiliary film forming resin, paint auxiliary agents, pigments, fillers and a matched curing agent based on formula amounts, the aliphatic nano organic titanium polyaspartic acid ester can be prepared to be environment-friendly and solvent-free nano organic titanium sea heavy duty anticorrosion paints.

Description

technical field [0001] The invention relates to a method for synthesizing aliphatic nano-organic titanium polyaspartate, a nano-organic titanium marine heavy-duty anti-corrosion coating and a preparation method thereof, belonging to the technical field of new materials. Background technique [0002] Corrosion is everywhere on Earth. "According to international practice, corrosion losses account for 3-5% of GDP, exceeding the sum of losses caused by fires, floods, droughts, typhoons and other disasters. In 2010, China's corrosion losses were at least 1.2 trillion yuan, and if effective measures are taken 25% to 40% of the losses can be avoided with the best corrosion protection measures. [0003] my country is not only a land power, but also a sea power. With the continuous expansion of the country's development of marine resources, sea-crossing bridges and sea-facing bridges are constantly being built as marine development infrastructure, and the total length of the cross-...
