High-durability self-lubricating on-demand anti-icing paint and coating thereof

Abstract

The invention provides a high-durability self-lubricating on-demand anti-icing coating and a coating thereof, and belongs to the technical field of anti-icing and deicing. The high-durability self-lubricating on-demand anti-icing coating has the lubricant self-release performance, boric acid components in the boric acid modified polymer in the coating and the lubricant containing reactive groups can form boric acid ester dynamic covalent bonds, hydrolysis can be carried out in a water-rich environment to release the free lubricant, interaction between a coating substrate and ice is shielded, and the anti-icing performance of the coating is improved. And the icing adhesive force is reduced. Since the free lubricant is generated only in the icing area, the coating has a directional deicing characteristic. The borate component of the coating in a non-icing area is not hydrolyzed, and the lubricant is stored in a solid form, so that the contact loss of the lubricant on the surface of a conventional self-lubricating coating is effectively avoided, and the durability of the coating is remarkably improved. In the anti-icing process, only a small amount of the lubricating agent which is hydrolyzed at the contact part is consumed, so that the surface still has extremely low icing bonding strength and high deicing durability after being subjected to multiple times of icing-deicing.

Description

Technical Field

[0001] The present invention relates to the technical field of anti-icing, and particularly relates to a highly durable self-lubricating on-demand anti-icing coating and its coating layer. Background Art

[0002] When outdoor infrastructure and engineering equipment surfaces are covered with ice, there are safety hazards, which are likely to cause serious casualties and significant economic losses. Coating with anti-icing coatings can significantly reduce the icing phenomenon on the substrate surface and reduce the adhesion force between the ice and the substrate, thereby reducing the harm of ice coverage. The smooth free lubricant on the surface of the self-lubricating coating can reduce the probability of ice crystal nucleation and reduce the surface ice coverage, and isolate the direct contact between the ice and the coating, thus reducing the ice adhesion force, and has good anti / de-icing performance. However, during the contact processes such as icing-deicing, the loss of the lubricant on the surface of the self-lubricating anti-icing coating will inevitably lead to the attenuation of the anti-icing performance of the coating. Therefore, it is imperative to develop a self-lubricating anti-icing coating with high durability.

[0003] Most of the anti-icing coatings on the market are low surface energy coatings containing fluorine and silicon, which can only limit the reduction of the adhesion force of the ice coverage on the substrate surface. Chinese patents CN201910460120.2, CN201810934239.4 and CN202010077993.8 respectively reported self-lubricating anti-icing coatings prepared by porous framework filled with lubricants based on modified bentonite, MOF membranes and foaming structures. Filling silicone oil or bionic synovial fluid effectively reduced the ice adhesion strength on the surface. However, none of them paid attention to the durability problem of the anti-icing surface. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a highly durable self-lubricating on-demand anti-icing coating and its coating layer. The highly durable self-lubricating on-demand anti-icing coating provided by the present invention has good self-lubricating effect and high de-icing durability.

[0005] In order to achieve the above-mentioned invention purpose, the present invention provides the following technical solutions:

[0006] The present invention provides a highly durable self-lubricating on-demand anti-icing coating, which comprises the following raw materials for preparation in parts by mass:

[0007]

[0008] The bifunctional group-terminated polymer includes a dihydroxy-terminated polymer or a diamino-terminated polymer.

[0009] Preferably, the dihydroxy-terminated polymer includes one or more of dihydroxy-terminated polydimethylsiloxane, perfluoropolyether diol, polyethylene glycol and polytetrahydrofuran; the diamino-terminated polymer includes diamino-terminated polydimethylsiloxane;

[0010] The molecular weight of the polymer capped with bifunctional groups is 1,000 to 7,500.

[0011] Preferably, the polyisocyanate includes one or more of toluene diisocyanate, isophorone diisocyanate, hexamethylene diisocyanate, diphenylmethane diisocyanate, hexamethylene diisocyanate trimer, and toluene diisocyanate trimer.

[0012] Preferably, the boric acid compound includes one or more of boric acid, hydroxybenzeneboronic acid, aminobenzeneboronic acid, and p-phenylenediboronic acid.

[0013] Preferably, the hydroxyl-containing polymer lubricant includes polyethylene glycol and / or hydroxyl silicone oil;

[0014] The molecular weight of the hydroxyl-containing polymer lubricant is 1,000 to 7,500.

[0015] The present invention provides a method for preparing the above-mentioned highly durable self-lubricating on-demand anti-icing coating, which includes the following steps:

[0016] Mix the polymer capped with bifunctional groups, polyisocyanate, organotin catalyst, and organic solvent, and carry out a polymerization reaction to obtain a polymer system;

[0017] Mix the boric acid compound with the polymer system and carry out a modification reaction to obtain a boric acid-modified polymer system;

[0018] Mix the boric acid-modified polymer system with a hydroxyl-containing lubricant to obtain a highly durable self-lubricating on-demand anti-icing coating.

[0019] Preferably, the temperature of the polymerization reaction is 40 to 90 °C, and the time is 12 to 24 h;

[0020] The temperature of the modification reaction is 50 to 80 °C, and the time is 12 to 24 h.

[0021] The present invention provides a highly durable self-lubricating on-demand anti-icing coating, which is obtained by curing the above-mentioned highly durable self-lubricating on-demand anti-icing coating.

[0022] Preferably, the temperature of the curing is 30 to 60 °C, and the time is 12 to 24 h.

[0023] The present invention provides the application of the above-mentioned highly durable self-lubricating on-demand anti-icing coating or highly durable self-lubricating on-demand anti-icing coating in the field of anti-icing and de-icing.

[0024] The present invention provides a highly durable self-lubricating on-demand anti-icing coating, which comprises the following raw materials for preparation in parts by mass: 20-70 parts of a polymer capped with bifunctional groups; 2.5-10 parts of a polyisocyanate; 1-5 parts of a boric acid compound; 20-60 parts of a hydroxyl-containing polymer lubricant; 10-40 parts of an organic solvent; and 0.01-0.05 parts of an organotin catalyst. The highly durable self-lubricating on-demand anti-icing coating provided by the present invention has the property of self-release of the lubricant. The boric acid component in the boric acid-modified polymer (polyurethane or polyurea) in the coating can form a borate dynamic covalent bond with the lubricant containing reactive groups, and can be hydrolyzed to release free lubricant in a water-rich environment, shielding the interaction between the coating substrate and ice and reducing the ice adhesion force. Since the free lubricant is only generated in the icing area, the coating has the characteristic of directional de-icing. In the non-icing area, the borate component of the coating does not hydrolyze, and the lubricant is stored in the coating in a solid form, which can effectively avoid the contact loss of the lubricant on the surface of the conventional self-lubricating coating and significantly improve the durability of the coating. Since only a small amount of lubricant that is hydrolyzed in the contact part is consumed during the anti-icing process, after undergoing multiple icing-de-icing cycles, the surface still has a very low ice adhesion strength and has high de-icing durability.

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0026] (1) In the highly durable self-lubricating on-demand anti-icing coating of the present invention, the lubricant can undergo dehydration condensation with the boric acid groups in the coating, bonding the free lubricant to the solid coating and avoiding the contact loss of the free lubricant in the traditional self-lubricating anti-icing coating.

[0027] (2) In the highly durable self-lubricating on-demand anti-icing coating of the present invention, the borate covalent bond can react with water molecules in a water-containing environment to release free lubricant and shield the strong interaction between the coating and water molecules, realizing the on-demand anti-icing application of the coating.

[0028] (3) The highly durable self-lubricating on-demand anti-icing coating of the present invention has extremely high de-icing durability. After 200 icing-de-icing applications, the surface of the coating still maintains a low ice adhesion strength, and the ice-repellent performance of the coating is not affected.

[0029] (4) The highly durable self-lubricating on-demand anti-icing coating provided by the present invention has a simple production process, diverse coating methods, and excellent de-icing durability, and can meet the actual application requirements. Description of the Drawings

[0079] Performance testing

[0080] (I) The surface of the highly durable self-lubricating on-demand anti-icing coating obtained in Example 1 was observed using a contact angle measuring instrument. 10 μL of deionized water was dropped onto the coating surface, and the surface state of the coating was observed. The surface of the highly durable self-lubricating on-demand anti-icing coating was as Figure 1 shown. It can be seen from Figure 1 that as the contact time between the deionized water and the coating increased, the lubricant was dissociated from the part of the surface of the highly durable self-lubricating on-demand anti-icing coating in contact with water. It shows that the highly durable self-lubricating on-demand anti-icing coating provided by the present invention can achieve on-demand release of the lubricant on the surface and has the characteristic of on-demand self-lubrication.

[0081] (II) The highly durable self-lubricating on-demand anti-icing coatings and carbon steel plates obtained in Examples 1 to 5 and Comparative Examples 1 to 2 were simultaneously fixed on a cold table at -10 °C and pre-cooled for 10 minutes. A 2 cm × 2 cm mold was used to drop deionized water on the coating and steel plate surfaces. After freezing for 1 h to form ice, the shear de-icing force value (F) on the coating and steel plate surfaces was measured using a force sensor, and the ice-covering strength (τ) was calculated through the formula τ = F / s, where the ice-covering area (s) was 4 cm 2 . The measured ice-covering strength results were as Figure 2 shown. It can be seen from Figure 2It can be seen that, compared with carbon steel plates, silicone-modified polyurethanes, and boric acid-modified polyurethanes, the high-durability self-lubricating ice-phobic coating provided by the present invention can significantly reduce the ice accretion intensity on the surface and has good ice-phobic and de-icing performance.

[0082] (III) The high-durability self-lubricating ice-phobic coating obtained in Example 1 was subjected to repeated icing-de-icing tests on a cold table at -10°C, and the change in ice accretion intensity with time was measured as Figure 3 shown. From Figure 3 it can be seen that the high-durability self-lubricating ice-phobic coating provided by the present invention has excellent ice-phobic durability, and the ice accretion intensity on the surface does not decay within 200 icing-de-icing cycles.

[0083] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
