[0039] A kind of anticorrosion material of the present embodiment, comprises the raw material of following weight portion:

[0040]

[0041] The additives are castor oil, dibutyl phthalate, crosslinking agent CN-01 and petroleum microcrystalline wax in a weight ratio of 1:1:0.5:0.5.

[0042] The mixed solvent is ethanol, butanone and DBE with a weight ratio of 1:2:7.

[0043] The preparation method of above-mentioned anticorrosion material, comprises the steps:

[0044] ⑴ dissolve

[0045] Weigh the mixed solvent and polymer resin respectively, then add the polymer resin into the mixed solvent while stirring, after stirring for 2 hours, place it in a constant temperature box, control the temperature at 80°C±1°C, and wait until the polymer resin is completely dissolved Afterwards, lower the temperature to 40°C for later use.

[0046] ⑵ preparation

[0047] Weigh and add additives, pigments, and fillers respectively, add them to the mixture obtained in step (1) in sequenc...

Embodiment 2

[0053] A kind of anticorrosion material of the present embodiment, comprises the raw material of following weight portion:

[0054]

[0055] The additives are castor oil, dibutyl phthalate, crosslinking agent CN-01 and petroleum microcrystalline wax in a weight ratio of 1:1:0.5:0.5.

[0056] The mixed solvent is ethanol, butanone and DBE with a weight ratio of 1:2:7.

[0057] The preparation method of above-mentioned anticorrosion material, comprises the steps:

[0058] ⑴ dissolve

[0059] Weigh the mixed solvent and polymer resin respectively, then add the polymer resin into the mixed solvent while stirring, after stirring for 2 hours, place it in a constant temperature box, control the temperature at 80°C±1°C, and wait until the polymer resin is completely dissolved Afterwards, lower the temperature to 40°C for later use.

[0060] ⑵ preparation

[0061] Weigh and add additives, pigments, and fillers respectively, add them to the mixture obtained in step (1) in sequenc...

Embodiment 3

[0078] Embodiment 3 application performance test

[0079] 1. The influence of solvent on the performance of anti-corrosion materials:

[0080] DBE: Polarity 3.4 Xylene: Polarity 2.5

[0081] Table 1

[0082]

[0083] illustrate:

[0084] The polarity of DBE is greater than the polarity of xylene. Under the condition of the same amount of solvent used, the amount of DBE dissolved resin is greater than the amount of dissolved xylene, and the dissolution time of DBE is faster than that of xylene.

[0085] Table 2

[0086]

[0087] illustrate:

[0088] Adhesion level 0 is the best, the higher the level, the worse the adhesion performance.

[0089] 2. The performance test results of the anticorrosion materials obtained in Example 1-2 and Comparative Example 1-2 are shown in Table 3:

[0090] table 3

[0091]

[0092] Description: Examples 1 and 2 are better than Comparative Examples 1 and 2 in terms of solid content, adhesion, impact strength and chemical stability....

Abstract

The invention discloses a corrosion-resistant material and a preparation method thereof. The corrosion-resistant material comprises raw materials in parts by weight as follows: 60 to 70 of a high molecule resin, 2 to 3 of an auxiliary, 10 to 20 of a mixed solvent, 1 to 3 of a pigment and 15 to 20 of a curing agent. The auxiliary is formed by mixing castor oil, dibutyl phthalate, a cross-linking agent CN-01 and petroleum microcrystalline wax in a weight ratio of 1: (0.8-1.2): (0.4-0.6): (0.4-0.6); and the mixed solvent is formed by ethanol, butanone and a dibasic ester (DBE) in a weight ratio of 1: (1.8-2.2): (6.5-7.5). According to the corrosion-resistant material and the preparation method thereof, the DBE and the petroleum microcrystalline wax which have unique characteristics are used, so that the corrosion-resistant material has the advantages of good leveling performance, pinhole freeness, good surface toughness, high adhesive force and curing degree, environmental protection and the like.

Description

technical field [0001] The invention relates to the field of anti-corrosion materials, in particular to an environment-friendly anti-corrosion material with strong adhesion and high curing content and a preparation method thereof. Background technique [0002] With the rapid development of China's economic construction, construction, transportation, petrochemical, energy, machinery and other fields have achieved rapid growth. With the rapid development of economy, environmental pollution has become increasingly serious. Corrosion is becoming more and more serious. According to incomplete statistics, the annual direct economic loss caused by corrosion accounts for about 1%-4% of the total output value of the national economy; therefore, it provides a broad development space for anti-corrosion materials. [0003] At present, the main problems of the existing anticorrosion materials are: poor adhesion to the base material, low curing content, and large environmental pollution. ...
