The powder coating is mainly characterized in that: has the characteristics of harmlessness, high efficiency, resource saving and environmental protection. Powder coatings can be divided into two broad categories: thermoplastic powder coatings and thermosetting powder coatings.
Firstly, the powder coating is thermoplastic or thermosetting, the curing temperature is between 180 ℃ and 200 ℃, and the curing time is long, so that the powder coating is limited to be only used for some heat-resistant base materials such as metal, and the curing agent of the polyester resin is commonly TGIC, although no volatile matter is emitted during curing and crosslinking, the curing agent is expensive and has high toxicity, so the selection of the curing agent and the problems possibly caused after the selection are needed to be researched; secondly, the conventional thermosetting powder coating is slightly insufficient in corrosion resistance, and cannot be applied to a corrosive environment. Therefore, we propose an environmentally friendly thermosetting powder coating and a method for preparing the same to solve the above problems.

The above examples 1-3 were all prepared by the following procedure:
s1, sequentially adding the polyester resin mixture, bis (N, N-dihydroxyethyl) adipamide, benzoin, a brightener, titanium dioxide, precipitated barium, benzoin resin and a corrosion-resistant additive into a reaction kettle, and stirring and uniformly mixing to obtain a mixed material;
s2, extruding the mixed material through a single-screw extruder, and cooling by a fan to obtain a semi-finished coating;

Test one: comparison of curing efficiency
The TGIC curative was used as a replacement for the curative in example 1, and the following control examples were set up:
comparative example: compared with example 1, except that the bis (N, N-dihydroxyethyl) adipamide and benzoin are changed into TGIC curing agent, the other raw materials are not changed;
compared with the preparation method of the embodiment 1, the preparation method of the comparative example is changed into the steps of adding the polyester resin mixture, the TGIC curing agent, the brightener, the titanium dioxide, the precipitated barium, the benzoin resin and the corrosion-resistant additive into a reaction kettle in sequence, stirring and uniformly mixing to obtain a mixed material except the step S1, and the other steps are consistent;
test subjects: the coatings in example 1 and comparative example 1;
the test method comprises the following steps: detecting on a 1.0mm aluminum plate by adopting a high-voltage electrostatic spraying method, controlling the thickness of a coating film to be 60-80 mu m, detecting and recording the time for curing and film-forming at different baking temperatures;
and (3) test results:
from the above test results, it can be seen that the film-forming curing efficiency of the coating material in example 1 is higher than that of the comparative example in comparison with the case where bis (N, N-dihydroxyethyl) adipamide is used as the curing agent and TGIC is used as the curing agent in the comparative example, and thus the curing speed of the powder coating material can be effectively increased by using bis (N, N-dihydroxyethyl) adipamide as the curing agent.
And (2) test II: degree of yellowing of coating when baked
Comparative example 1: compared with the example 1, the raw materials are consistent except that the raw materials do not contain benzoin;
comparative example 2: compared with the example 2, the raw materials are consistent except that the raw materials do not contain benzoin;
comparative example 3: compared with the example 3, the raw materials are consistent except that the raw materials do not contain benzoin;
compared with the preparation methods of examples 1 to 3, the preparation methods of comparative examples 1 to 3 do not change except that the step of S1 is changed into the steps of adding the polyester resin mixture, bis (N, N-dihydroxyethyl) adipamide, the brightener, titanium dioxide, precipitated barium, benzoin resin and the corrosion-resistant additive into a reaction kettle in sequence, and obtaining a mixed material after uniformly stirring.
Test subjects: the coatings in examples 1-3 and comparative examples 1-3;
the test method comprises the following steps: detecting a 1.0mm test plate by adopting a high-voltage electrostatic spraying method, controlling the thickness of a coating film to be 60-80 mu m, hanging the test plate in a pre-heated oven for baking under the baking condition of 200 ℃/10min, taking out the test plate from the oven after baking, and recording the yellowing degree of a coating film on the test plate;
and (3) test results:
from the above test results, it is found that when bis (N, N-dihydroxyethyl) adipamide is used as a curing agent in a coating material, yellowing is very likely to occur on a formed coating film after baking without adding benzoin, and such yellowing can be effectively improved with the addition of benzoin.
And (3) test III: determination of Corrosion resistance
Comparative example 4: compared with the example 1, the raw materials are consistent except that the corrosion-resistant additive is not added;
comparative example 5: compared with the example 2, the raw materials are consistent except that the corrosion-resistant additive is not added;
comparative example 6: compared with the example 3, the raw materials are consistent except that the corrosion-resistant additive is not added;
compared with the preparation methods of examples 1 to 3, the preparation methods of comparative examples 4 to 6 do not change except that the step of S1 is changed into the steps of adding the polyester resin mixture, bis (N, N-dihydroxyethyl) adipamide, benzoin, the gloss enhancer, titanium dioxide, precipitated barium and benzoin resin into a reaction kettle in sequence, and obtaining a mixed material after stirring and uniformly mixing.
Test subjects: the coatings in examples 1-3 and comparative examples 4-6;
the test method comprises the following steps: detecting on a 1.0mm test board by adopting a high-voltage electrostatic spraying method, controlling the thickness of a coating film to be 60-80 mu m, then suspending the test board in an oven for heat treatment to enable the coating on the test board to form a film, respectively carrying out corrosion resistance tests according to an artificial atmosphere corrosion test salt spray test (acetate salt spray) method disclosed in GB/T10125-;
and (3) test results:
as can be seen from the test results in the above table, the coatings of examples 1-3 have good corrosion resistance, while the coatings of comparative examples 4-6 have relatively poor corrosion resistance, and the examples and comparative examples are distinguished by the presence or absence of the corrosion-resistant additive in each test group, so that the corrosion-resistant performance of the coatings after film formation can be effectively improved by the added corrosion-resistant additive.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
