Description

Technical Field

[0001] This invention belongs to the field of coating technology, specifically relating to a fast-drying micaceous iron oxide epoxy ester anti-rust paint and its preparation method. Background Technology

[0002] Epoxy ester coatings are single-component, self-drying industrial coatings widely used in metal anti-rust coatings due to their high cost-effectiveness and ease of application. Epoxy ester coatings are made from high-molecular-weight epoxy esters produced by the esterification reaction of epoxy resin and vegetable oil fatty acids, combined with pigments, fillers, additives, and solvents. They combine the adhesion of epoxy resin with the oxidative cross-linking drying properties of fatty acids. The curing mechanism of this coating relies on the oxidative polymerization of unsaturated fatty acid groups, allowing for room temperature curing or heat-drying curing. Application is convenient, using various methods such as brushing and spraying. They are mainly used in civilian fields such as floor paints, stadium facility coatings, and metal decorative coatings, and are also being expanded to be used as primers for automobiles and steel structures.

[0003] Currently, micaceous iron oxide epoxy ester anti-rust paint is a widely used single-component room temperature self-drying epoxy paint. However, it still suffers from problems such as long wet film drying time and poor anti-rust performance. For example, in tests such as cyclic salt spray and damp heat aging, the corrosion resistance of traditional epoxy ester paints deteriorates rapidly. Furthermore, traditional epoxy ester paints require 20-48 hours to fully dry, and the recoating interval is at least 12-24 hours, severely impacting construction efficiency and project progress. Therefore, further research is needed to address the fast-drying and anti-rust issues of current traditional epoxy paints and to provide a fast-drying micaceous iron oxide epoxy ester anti-rust paint.

(3) By mass, add 40-60 parts of epoxy ester resin to 8-12 parts of solvent, heat to 115-125℃, add component A dropwise, and continue to keep warm for 1-1.5h after the addition is complete; (4) Heat the component from step (3) to 130-135℃, add component B dropwise, and continue to keep warm for 2-3 hours after the addition is complete. Then cool down, filter, and obtain the final product.

[0008] Preferably, in step A, the mass ratio of talc, aqueous ethanol solution, and silane coupling agent is (20-25):(70-80):(5.5-6.5); the mass percentage of the aqueous ethanol solution is 90-95%; the silane coupling agent is γ-aminopropyltriethoxysilane; the reaction temperature is 40-50℃, and the reaction time is 3-5h.

[0009] Preferably, in step B, the ratio of pretreated talc, DMF, 5-O-feruloylshikimic acid, EDC, and DMAP is 1g:10mL:0.1-0.12g:0.4-0.5g:0.1-0.12g; the reaction temperature is 50-60℃, and the reaction time is 3-5h.

[0010] Preferably, in step C, the ratio of 5-O-feruloylshikimic acid-modified talc, DMF, triallyl phosphate, and initiator A is 10g:100mL:1.2-1.5g:0.05-0.08g; the initiator A is azobisisobutyronitrile; the reaction temperature is 80-90℃, and the reaction time is 1-3h.

[0014] This invention provides a method for preparing a fast-drying micaceous iron oxide ester anti-rust paint. The preparation method is as follows: mix the components according to the raw material ratio to obtain the paint.

[0015] The beneficial technical effects of this invention are as follows: This invention provides a fast-drying micaceous iron oxide epoxy ester anti-rust paint, wherein the modified epoxy ester resin uses epoxy ester resin as a grafting skeleton, grafted with acrylate copolymer and phosphorus-containing compound, which can effectively shorten the drying time of micaceous iron oxide epoxy ester anti-rust paint, shortening the surface drying time to less than 0.5 hours and the actual drying time to less than 12 hours.

[0016] In the preparation process of the filler of this invention, talc powder is first modified with a silane coupling agent. An amino group is introduced into the pretreated talc powder, and the amino group reacts with the carboxyl group in 5-O-feruloylshikimic acid. Then, under the action of an initiator, the double bonds in 5-O-feruloylshikimic acid and the three allyl double bonds in triallyl phosphate copolymerize to form a dense cross-linked organic layer. The modified filler has better compatibility with the epoxy ester resin matrix, avoiding agglomeration. The interfacial bonding between the filler and the epoxy resin is stronger, reducing microcracks caused by thermal expansion and contraction, and improving adhesion. The introduction of 5-O-feruloylshikimic acid provides phenolic hydroxyl groups and conjugated double bonds to the surface of the talc powder. The phenolic hydroxyl groups are antioxidants, and the conjugated double bonds improve the density of the paint film, reduce the penetration of corrosive media, and have good weather resistance and anti-penetration effects. Combined with the highly cross-linked phosphate polymer of the outer layer, it can effectively block the penetration of water, oxygen, etc. The phosphate groups can form a stable chelated passivation film with the metal substrate to improve the rust prevention effect.

[0017] This invention provides a method for preparing a fast-drying micaceous iron oxide ester anti-rust paint. This process is simple to operate and suitable for industrial promotion and application. Attached Figure Description

[0032] Comparative Example 1 The difference between this comparative example and Example 1 is that the modified epoxy ester resin is replaced with epoxy ester resin, while the rest is the same as Example 1.

[0033] Comparative Example 2 The difference between this comparative example and Example 1 is that the filler is replaced with pretreated talc powder, otherwise it is the same as Example 1.

[0034] Comparative Example 3 The difference between this comparative example and Example 1 is that the silane coupling agent in step A is replaced with vinyltriethoxysilane, step B is omitted, and the pretreated talc powder obtained in step A is directly added to step C. Otherwise, it is the same as Example 1.

[0035] Comparative Example 4 The difference between this comparative example and Example 1 is that the filler is replaced with talc and 5-O-feruloylshikimic acid, otherwise it is the same as Example 1.

[0036] Test case The fast-drying micaceous iron oxide epoxy ester anti-rust paints prepared in Examples 1-3 and Comparative Examples 1-4 were applied to substrates, and the surface drying time, actual drying time, adhesion, water resistance, and neutral salt spray resistance of the paint film were measured. The results are shown in Table 1.

[0037] Specifically, the surface drying time and actual drying time of the paint film were determined according to GB / T1728 "Determination of Drying Time of Paint Film and Putty Film". The adhesion of the paint film was determined according to GB / T5210 "Adhesion Test by Pull-Off Method for Paints and Varnishes". The water resistance of the paint film was determined according to GB / T9274 "Determination of Resistance to Liquid Media for Paints and Varnishes". The resistance to neutral salt spray of the paint film was determined according to GB / T1771 "Determination of Resistance to Neutral Salt Spray for Paints and Varnishes".

[0038] Table 1 Group Drying time (min) Actual working time (h) Adhesion (MPa) Water resistance (240h) Resistance to neutral salt spray (h) Example 1 24 8 8.4 No abnormalities 550 Example 2 26 9 8.2 No abnormalities 530 Example 3 30 10 8.1 No abnormalities 500 Comparative Example 1 90 24 7.5 Minor abnormality 480 Comparative Example 2 42 14 5.8 Medium foaming 360 Comparative Example 3 38 12 6.3 Medium foaming 390 Comparative Example 4 45 15 5.2 Medium foaming 320

[0039] As shown in Table 1, compared to Comparative Examples 1-4, the drying time of the paint films obtained in Examples 1-3 of this invention is shorter, with the surface drying time shortened to less than 0.5 hours and the actual drying time shortened to less than 12 hours. Simultaneously, the paint films obtained in Examples 1-3 of this invention exhibit better water resistance and neutral salt spray resistance. The reason for this is that the modified epoxy ester resin of this invention uses epoxy ester resin as a grafting skeleton, grafting acrylate copolymers and phosphorus-containing compounds, which effectively shortens the drying time of the micaceous iron oxide epoxy ester anti-rust paint. This invention first uses a silane coupling agent to modify talc powder to introduce amino groups. The amino groups react with the carboxyl groups in 5-O-feruloylshikimic acid. Then, under the action of an initiator, the double bonds in 5-O-feruloylshikimic acid and the three allyl double bonds in triallyl phosphate copolymerize to form a dense cross-linked organic layer, obtaining the modified filler. The modified filler of this invention has better compatibility with the epoxy ester resin matrix, stronger interfacial bonding, and better adhesion. Meanwhile, the introduction of 5-O-feruloylshikimic acid provides phenolic hydroxyl groups and conjugated double bonds to the surface of talc, which can reduce the penetration of corrosive media. Combined with phosphate ester polymers, it can effectively block the penetration of water, oxygen and other substances, and improve the rust prevention effect.

The basic principles and main features of the present invention have been described above with specific implementation schemes. Based on the present invention, some modifications or substitutions can be made, but these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of protection claimed by the present invention.
