Description

Technical Field

[0001] This invention relates to the field of topcoat technology, specifically to an anti-slip topcoat and its preparation method. Background Technology

[0002] Topcoat is the outermost layer of paint in decoration, serving both aesthetic and protective functions. It can be applied to walls, sports fields, and other areas. Topcoat used on sports fields not only needs good weather resistance and waterproofing, but also excellent abrasion resistance and slip resistance.

[0003] Currently, the topcoats used in sports fields are mainly silicone PU topcoats and acrylic topcoats. Although they have good weather resistance, abrasion resistance, scratch resistance, and tear resistance, their anti-slip properties are poor. Anti-slip properties are a crucial indicator for sports field topcoats, directly affecting athletes' safety and comfort. Therefore, providing a non-slip topcoat is a pressing technical challenge that needs to be addressed in this field. Summary of the Invention

[0004] This invention proposes an anti-slip topcoat and its preparation method, which solves the problem of poor anti-slip properties of topcoats in related technologies.

[0005] The technical solution of the present invention is as follows:

[0006] An anti-slip topcoat includes component A and component B. Component A comprises the following raw materials in parts by weight: 20-30 parts hydroxypropyl emulsion, 30-40 parts PUD emulsion, 70-90 parts anti-slip filler, 1-2 parts film-forming aid, 0.1-0.5 parts defoamer, 0.3-0.8 parts wetting agent, 0.5-1.5 parts thickener, and 25-35 parts water. Component B comprises the following raw materials in parts by weight: 4-10 parts curing agent. The anti-slip filler comprises silicon carbide and quartz sand.

[0007] As a further technical solution, the mass ratio of silicon carbide to quartz sand is 1:6~14.

[0009] As a further technical solution, the silicon carbide includes silicon carbide nanopowder and silicon carbide nanowires in a mass ratio of 1:1 to 4.

[0010] As a further technical solution, the silicon carbide comprises silicon carbide nanopowder and silicon carbide nanowires in a mass ratio of 1:3.

[0011] This invention limits silicon carbide to silicon carbide nanopowder and silicon carbide nanowires in a mass ratio of 1:3, which further improves the anti-slip and wear resistance of the topcoat.

[0012] As a further technical solution, the preparation method of the anti-slip filler includes the following steps: mixing silicon carbide and quartz sand, and then grinding them to obtain the anti-slip filler.

[0013] This invention further improves the anti-slip properties and abrasion resistance of the topcoat by specifying the preparation method of the anti-slip filler.

[0014] As a further technical solution, the anti-slip filler is a modified anti-slip filler, which includes one or two of PU-modified epoxy vinyl ester resin modified anti-slip fillers and flexible epoxy vinyl ester resin modified anti-slip fillers.

[0015] This invention limits the anti-slip filler to modified anti-slip filler, which includes one or two of PU-modified epoxy vinyl ester resin modified anti-slip filler and flexible epoxy vinyl ester resin modified anti-slip filler, further improving the anti-slip and wear resistance of the topcoat.

[0016] As a further technical solution, when the modified anti-slip filler includes PU-modified epoxy vinyl ester resin-modified anti-slip filler and flexible epoxy vinyl ester resin-modified anti-slip filler, the mass of the PU-modified epoxy vinyl ester resin-modified anti-slip filler is greater than or equal to the mass of the flexible epoxy vinyl ester resin-modified anti-slip filler.

[0017] This invention limits the modified anti-slip filler to PU-modified epoxy vinyl ester resin modified anti-slip filler and flexible epoxy vinyl ester resin modified anti-slip filler, and limits the mass of PU-modified epoxy vinyl ester resin modified anti-slip filler to be greater than or equal to the mass of flexible epoxy vinyl ester resin modified anti-slip filler, thereby further improving the anti-slip and wear resistance of the topcoat.

[0018] As a further technical solution, the modified anti-slip filler includes PU-modified epoxy vinyl ester resin modified anti-slip filler and flexible epoxy vinyl ester resin modified anti-slip filler with a mass ratio of 10:6 to 9:7.

[0019] This invention limits the modified anti-slip filler to PU-modified epoxy vinyl ester resin modified anti-slip filler and flexible epoxy vinyl ester resin modified anti-slip filler with a mass ratio of 10:6 to 9:7, which further improves the anti-slip and wear resistance of the topcoat.

[0020] As a further technical solution, the raw materials of the PU modified epoxy vinyl ester resin modified antislip filler include PU modified epoxy vinyl ester resin and antislip filler in a mass ratio of 0.3~0.8:1, and the raw materials of the flexible epoxy vinyl ester resin modified antislip filler include flexible epoxy vinyl ester resin and antislip filler in a mass ratio of 0.3~0.8:1.

[0021] As a further technical solution, the PU-modified epoxy vinyl ester resin can be any type of PU-modified epoxy vinyl ester resin, preferably Fuchen vinyl ester resin 820.

[0022] As a further technical solution, the flexible epoxy vinyl ester resin can be any type of flexible epoxy vinyl ester resin, preferably Fuchen vinyl ester resin 810.

[0023] As a further technical solution, the preparation method of the PU-modified epoxy vinyl ester resin modified anti-slip filler includes the following steps: mixing PU-modified epoxy vinyl ester resin with styrene, adding anti-slip filler and mixing evenly, filtering, and drying to obtain PU-modified epoxy vinyl ester resin modified anti-slip filler.

[0024] As a further technical solution, the preparation method of the flexible epoxy vinyl ester resin modified anti-slip filler includes the following steps: mixing flexible epoxy vinyl ester resin with styrene, adding anti-slip filler and mixing evenly, filtering, and drying to obtain flexible epoxy vinyl ester resin modified anti-slip filler.

[0025] The present invention also proposes a method for preparing the anti-slip topcoat, comprising the following steps: mixing the raw materials of component A evenly and then mixing them with the raw materials of component B to obtain the anti-slip topcoat.

[0026] The working principle and beneficial effects of this invention are as follows:

Component A includes hydroxypropyl emulsion, PUD emulsion, anti-slip filler, film-forming aid, defoamer, wetting agent, thickener, and water. Component B includes a curing agent. The anti-slip filler includes silicon carbide and quartz sand. By using silicon carbide and quartz sand in combination, the anti-slip properties and wear resistance of the topcoat are significantly improved. Detailed Implementation

[0091] After mixing 25 parts of hydroxypropyl emulsion, 35 parts of PUD emulsion, 80 parts of silicon carbide nanoparticles, 1.5 parts of film-forming aid, 0.3 parts of defoamer, 0.5 parts of wetting agent, 1 part of thickener, and 30 parts of water evenly, the mixture is then mixed with 7 parts of curing agent to obtain an anti-slip topcoat.

[0094] The anti-slip topcoats obtained in Examples 1-15 and Comparative Examples 1-2 were made into coatings with a thickness of 100 μm. The abrasion resistance test at 750 g / 500 r was conducted according to the method in GB / T1768-2006, and the anti-slip test was conducted according to the method in GB / T 9263-2020. The test results are recorded in Table 1.

[0095] Table 1. Anti-slip properties and abrasion resistance of anti-slip topcoat

[0096]

[0097] As can be seen from Table 1, the topcoat provided by the present invention has good anti-slip and wear resistance.

[0098] Compared with Comparative Examples 1-2, Examples 1-15 used silicon carbide and quartz sand, Comparative Example 1 used silicon carbide, and Comparative Example 2 used quartz sand. The dry static friction coefficient of the topcoat obtained in Examples 1-15 was higher than that of Comparative Examples 1-2, and the average mass loss was lower than that of Comparative Examples 1-2. This shows that the combined use of silicon carbide and quartz sand can improve the anti-slip and wear resistance of the topcoat.

[0099] The dry static friction coefficient of the topcoat obtained in Example 6 is higher than that of Examples 1, 4-5 and 7, and the average mass loss is lower than that of Examples 1, 4-5 and 7. This indicates that silicon carbide nanopowder and silicon carbide nanowires in a mass ratio of 1:3 can further improve the anti-slip and wear resistance of the topcoat.

[0100] The dry static friction coefficient of the topcoat obtained in Example 8 is higher than that in Example 6, and the average mass loss is lower than that in Example 6, indicating that by limiting the preparation method of the anti-slip filler, the anti-slip properties and wear resistance of the topcoat can be further improved.

[0101] The dry static friction coefficient of the topcoat obtained in Examples 9-15 is higher than that in Example 8, and the average mass loss is lower than that in Example 8, indicating that the anti-slip filler is a modified anti-slip filler. When the modified anti-slip filler includes PU modified epoxy vinyl ester resin modified anti-slip filler and / or flexible epoxy vinyl ester resin modified anti-slip filler, the anti-slip and wear resistance of the topcoat can be further improved.

[0102] The dry static friction coefficient of the topcoat obtained in Examples 12-15 is higher than that in Examples 9-11, and the average mass loss is lower than that in Examples 9-11. This indicates that the modified anti-slip filler is a PU-modified epoxy vinyl ester resin modified anti-slip filler and a flexible epoxy vinyl ester resin modified anti-slip filler. At the same time, when the mass of the PU-modified epoxy vinyl ester resin modified anti-slip filler is greater than or equal to the mass of the flexible epoxy vinyl ester resin modified anti-slip filler, the anti-slip and wear resistance of the topcoat can be further improved.

[0103] The dry static friction coefficient of the topcoat obtained in Examples 13-14 is higher than that in Examples 12 and 15, and the average mass loss is lower than that in Examples 12 and 15. This indicates that the modified anti-slip filler, which is a PU-modified epoxy vinyl ester resin modified anti-slip filler and a flexible epoxy vinyl ester resin modified anti-slip filler with a mass ratio of 10:6 to 9:7, can further improve the anti-slip and wear resistance of the topcoat.

[0104] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
