Description

Technical Field

[0001] This invention belongs to the field of floor coating technology, and relates to a high wear-resistant floor coating based on TiC hybrid resin and its preparation process. Background Technology

[0002] Floor coatings, as key materials that protect concrete substrates and impart specific functions, are widely used in industrial plants, warehouses, hospitals, shopping malls, and underground parking garages. Among them, epoxy resin floor coatings dominate the market due to their excellent adhesion, mechanical strength, chemical corrosion resistance, and solvent-free environmental protection properties.

[0003] Currently, the main method to improve the wear resistance of epoxy floor coatings is to add hard wear-resistant fillers, such as quartz sand, silicon carbide, and alumina, to the coating system. However, this traditional method has many inherent drawbacks: 1. The contradiction between wear resistance and toughness: Adding a large amount of hard fillers to improve wear resistance will lead to a significant decrease in the flexibility and impact resistance of the coating; 2. The problem of interfacial bonding between fillers and resin: Most inorganic fillers have poor compatibility with organic epoxy resins and weak interfacial bonding, which not only fails to play a wear-resistant role but also accelerates the wear of the coating as an abrasive; 3. The problem of dispersing nanofillers: Aggregates not only greatly reduce the reinforcing effect but also become structural defects in the coating.

[0004] Therefore, there is an urgent need in this field to develop a new type of high-wear-resistant, high-performance floor coating to overcome the problems caused by traditional epoxy resin coatings with added fillers. Summary of the Invention

[0005] The purpose of this invention is to provide a high wear-resistant floor coating based on TiC hybrid resin and its preparation process, the prepared floor coating having excellent wear resistance.

[0006] The objective of this invention can be achieved through the following technical solutions: A high-abrasion-resistant floor coating based on TiC hybrid resin, the high-abrasion-resistant floor coating comprising the following components A and B in parts by weight: Component A: 90-100 parts of modified waterborne epoxy resin emulsion; Component B: 20-30 parts modified fibrous wollastonite, 0.5-1.5 parts leveling agent, 0.5-1 part defoamer, 1-2 parts wetting and dispersing agent, 30-45 parts water-based amine curing agent, 20-40 parts water; The weight ratio of component A to component B is 1:(0.75~0.85); The modified waterborne epoxy resin emulsion is obtained by modifying waterborne epoxy resin emulsion with titanium carbide, and the modified titanium carbide is obtained by treatment with KH550 and carboxyl-terminated polycaprolactone.

[0007] As a preferred embodiment of the present invention, the preparation process of the modified waterborne epoxy resin emulsion is as follows: S2.1 Mix amino-modified titanium carbide, carboxyl-terminated polycaprolactone and anhydrous ethanol in a ratio of 0.2g:0.1g:100mL and stir at 50°C to obtain a mixture; S2.2 Add N-hydroxysuccinimide and 1-ethyl-(3-dimethylaminopropyl)carbodiimide hydrochloride to the mixture, stir at 300 rpm for 30 min, then add mixture B, stir at 400 rpm for 2-4 h at 68-74 °C under N2 atmosphere, cool naturally to room temperature, centrifuge to remove the solution, wash with anhydrous ethanol, and vacuum dry at 40 °C for 20-28 h to obtain modified titanium carbide; S2.3. Modified titanium carbide with a mass ratio of (3~5):100 is mixed and stirred with waterborne epoxy resin emulsion to obtain modified waterborne epoxy resin emulsion.

[0008] As a preferred embodiment of the present invention, the preparation steps of the modified fibrous wollastonite are as follows: According to the weight proportions, the fibrous wollastonite was dried by blowing at 100~105℃ for 2h, immersed in the modification liquid, ultrasonically dispersed at 250~350W for 30~40min, stirred and refluxed at 80~85℃ for 3~5h, and vacuum dried at 80℃ for 10~12h to obtain the modified fibrous wollastonite.

[0009] As a preferred embodiment of the present invention, the leveling agent is one or more of polydimethylsiloxane, 1,2-propanediol, BYK-333, and BYK-349.

[0010] As a preferred embodiment of the present invention, the defoamer is one of BYK-033, TEGOFoamex8050, Hemings 6800 type defoamer, and water-based defoamer BW-227.

[0011] As a preferred embodiment of the present invention, the dispersant is one or more of polyether-modified polysiloxane compounds, BYK-190, BYK-2225, and BYK-2155.

[0012] As a preferred embodiment of the present invention, the preparation process of the aminated titanium carbide in step S2.1 is as follows: Nano-titanium carbide and KH550 were added to an ethanol / water mixed solvent with a volume ratio of 95:5 (2g:0.4g:200mL). The pH of the solution was adjusted to 4-5. The mixture was stirred at 300rpm for 4 hours at 60-70℃, allowed to cool naturally to room temperature, filtered, and dried at 70℃ for 12 hours to obtain aminated titanium carbide.

[0013] As a preferred embodiment of the present invention, in step S2.2, the molar ratio of N-hydroxysuccinimide, 1-ethyl-(3-dimethylaminopropyl)carbodiimide hydrochloride and carboxyl-terminated polycaprolactone is 0.6:0.5:1.

[0014] As a preferred embodiment of the present invention, the modified solution is prepared by mixing 3-8 parts of 1-(triethoxysilyl)propyl-3-methylimidazolium chloride, 1-3 parts of KH-560 and 200 parts of anhydrous ethanol, adding 10-20 parts of water, adjusting the pH to 4-5, and stirring at 40-50°C for 2-3 hours to obtain the modified solution.

[0015] A preparation process for a high-wear-resistant floor coating based on TiC hybrid resin is described below: S1. According to the weight parts, the modified fibrous wollastonite, wetting agent, leveling agent, defoamer, dispersant, water-based amine curing agent and water are mixed to obtain component B; S2. Mix component A and component B to prepare the high wear-resistant floor coating.

[0016] In this invention, amino groups are first introduced onto the surface of titanium carbide using a silane coupling agent. This significantly improves the organic solvent affinity and resin compatibility of titanium carbide, reducing its tendency to agglomerate. Furthermore, by grafting carboxylated polycaprolactone long chains onto the surface amino groups, a flexible polymer interface layer is introduced between the rigid titanium carbide and epoxy resin. This layer exhibits excellent compatibility with epoxy resin, allowing for uniform nanoscale dispersion through simple mechanical stirring without the need for high-intensity shearing or grinding. This overcomes the problem of strong nanoparticle agglomeration, stress defect points, and poor interfacial bonding caused by traditional direct mixing of titanium carbide.

[0017] Mixing 3-5% of modified titanium carbide with an aqueous epoxy resin emulsion significantly improves performance while avoiding excessive addition that leads to increased viscosity and construction difficulty. The PCL shell, as a long polymer chain, can interpenetrate and entangle with the epoxy resin molecular chains, thus better dispersing and transferring stress and preventing stress concentration. Furthermore, the terminal -COOH functional groups of the terminal carboxylated polycaprolactone can react with the epoxy groups of the epoxy resin or the amino groups of the curing agent, allowing the titanium carbide to become part of the cross-linked network through chemical bonds, achieving true hybridization.

[0018] Therefore, this strong interfacial bonding force allows stress (external force) to be efficiently transferred from the relatively soft resin matrix to the extremely hard titanium carbide core, thereby giving full play to the reinforcing and wear-resistant effects of titanium carbide. This fundamentally solves the problems of poor compatibility between nanoparticles and the matrix and interfacial debonding, and can significantly improve the wear resistance and adhesion of the floor coating.

[0019] Fibrous wollastonite, acting as a reinforcing phase, forms a three-dimensional network structure in the coating, significantly reducing shrinkage and internal stress, ensuring dimensional stability, stronger adhesion, and reducing the likelihood of peeling due to stress concentration. After treatment with the modification liquid, the epoxy groups of KH-560 can directly undergo a ring-opening reaction with the epoxy curing agent (amine) to form a robust covalent network, while the long chain of 1-(triethoxysilyl)propyl-3-methylimidazolium chloride provides strong steric hindrance and enhances antistatic properties.

[0020] The beneficial effects of this invention are: This invention provides a high wear-resistant floor coating system. The system used is a water-based epoxy resin coating system, in which water-based epoxy resin and water-based amine curing agent are cured and crosslinked. Modified titanium carbide is mixed into the water-based epoxy resin emulsion, transforming titanium carbide from a traditional physical filler into a part of the epoxy resin crosslinking network. Modified fibrous wollastonite and titanium carbide particles form a fiber-particle synergistic wear-resistant skeleton, with the fibers playing a supporting and connecting role, preventing the titanium carbide particles from being removed during wear. The titanium carbide is treated with amination and surface grafting with polycaprolactone to improve the compatibility between components, thereby improving the wear resistance of the floor coating.
