AI Technical Summary
The existing thick-coated elastic self-leveling coatings lack anti-slip capability in sports fields due to smooth surfaces, and during the jumping process of sports personnel, they are prone to squeezing the interior and surfaces, resulting in cracks and damage.
The compressive, impact-resistant and anti-slip dispersion unit is uniformly distributed in the self-leveling water-based coating. The dispersion unit is composed of a floating member and a sinking member. After curing, the floating member protrudes from the surface, and the sinking member contacts the base surface, forming a paint cage cavity, conducting the punch pressure into the paint cage to avoid surface and internal squeezing.
The anti-slip performance and anti-stamping ability of self-leveling water-based coatings are achieved, which avoids shear and fatigue damage on the surface and inside, and extends the service life of the coating.

Abstract
Description
Technical Field
[0001] The present invention belongs to the field of coatings. Background Art
[0002] Thick - coated elastic self - leveling coating (8 - 10 mm or thicker) is mainly applied to scenarios such as sports fields, so as to buffer the process of athletes' bouncing. While effectively protecting the knees of sports personnel, it reduces the noise caused by athletes' bouncing. Since the surface of the thick - coated water - borne polyurethane self - leveling coating is smooth and flat after curing, it does not have anti - slip ability. At the same time, although the 8 - 10 mm or thicker polyurethane self - leveling coating brings stronger noise reduction and knee impact mitigation, it will also be internally and superficially displaced due to the impact force brought by the soles of sports personnel during bouncing, thus forming a large displacement shear force, which will eventually lead to cracks and damage problems over time. Summary of the Invention
[0003] Object of the Invention: In order to overcome the deficiencies in the prior art, the present invention provides an anti - slip and impact - resistant self - leveling water - borne coating and its process, which has anti - slip and anti - punching properties.
[0004] Technical Solution: To achieve the above object, in an anti - slip and impact - resistant self - leveling water - borne coating of the present invention, a number of compressive, impact - resistant and anti - slip scattering units are evenly and discretely distributed in the self - leveling water - borne coating; the lower ends of each compressive, impact - resistant and anti - slip scattering unit are in contact with the self - leveling base surface, and the upper ends of each compressive, impact - resistant and anti - slip scattering unit protrude in an arc shape above the surface of the self - leveling water - borne coating.
[0005] The compressive, impact - resistant and anti - slip scattering unit is composed of a floating member and a sinking member; in the fluid state before the self - leveling water - borne coating cures, the floating member floats to the top and protrudes above the surface of the self - leveling water - borne coating, and after the sinking member sinks to contact the self - leveling base surface, the lower end of the floating member and the upper end of the sinking member still do not separate.
[0006] Further, the floating member includes a spherical - arc surface top plate, the lower end of the spherical - arc surface top plate is integrally and coaxially connected with a central column, and there is a hollow chamber inside the spherical - arc surface top plate, making the floating member lighter at the top and heavier at the bottom, and the overall density of the floating member is less than the density of the self - leveling water - borne coating in the fluid state.
[0007] Further, the sinking member includes a bell - shaped cover, and a central column through - hole is coaxially hollowed out at the top of the bell - shaped cover; the central column passes downward through the central column through - hole, and there is a clearance fit between the outer wall of the central column and the inner wall of the central column through - hole.
[0008] Further, a number of air - bubble overflow holes are arranged in a circular array around the central column through - hole at the upper end of the bell - shaped cover, and a thickened weight portion is arranged in a circle along the contour at the lower end of the bell - shaped cover.
[0009] Furthermore, when the anti-compression, anti-impact and anti-slip scattering unit has not been scattered into the self-leveling water-based paint coating in a fluid state, the upper contour of the bell-shaped cover is adhered to the lower surface of the arc-shaped top plate through a water-soluble adhesive. When the anti-compression, anti-impact and anti-slip scattering unit is scattered into the self-leveling water-based paint coating in a fluid state, the water-soluble adhesive at the adhesion between the upper contour of the bell-shaped cover and the lower surface of the arc-shaped top plate is dissolved by the water or liquid other than water in the self-leveling water-based paint coating in a fluid state, thereby releasing the constraint of the water-soluble adhesive on the floating member and the sinking member; and then the bell-shaped cover sinks under the action of gravity to contact the self-leveling base surface, forming a paint cage cavity filled with water-based paint inside the bell-shaped cover. At the same time, the spherical arc-shaped top plate floats up to protrude from the surface of the self-leveling water-based paint coating in a fluid state. At this time, the lower end of the central column is still sleeved in the through hole of the central column, so that the lower end of the floating member and the upper end of the sinking member are still not separated at this time.
[0010] Furthermore, both the floating member and the sinking member are made of metal.
[0011] Furthermore, before sowing, the height dimension and width dimension of the anti-compression, anti-impact and anti-slip scattering unit are both smaller than the thickness of the self-leveling water-based paint coating; the height dimension of the floating member + the height dimension of the sinking member is not less than the self-leveling water-based paint coating.
[0012] Furthermore, the paint emulsion ratio of the fluid and uncured self-leveling water-based paint coating is as follows: 55-70 parts of polyurethane resin, 30-50 parts of filler, 35-45 parts of water, 16-20 parts of dimethylaminoethyl acrylate, 3-4 parts of diluent, 15-17 parts of curing agent, 2 parts of leveling agent, 2-9 parts of dispersant, 0.5-1 part of defoaming agent.
[0013] Furthermore, the self-leveling process of the self-leveling water-based paint coating:
[0014] Step 1, pour the self-leveling water-based paint emulsion on the self-leveling base surface in the enclosed area, and the emulsion levels itself under the action of gravity;
[0015] Step 2, evenly scatter a number of anti-compression, anti-impact and anti-slip scattering units in a discrete state into the flowing self-leveling water-based paint emulsion.
[0016] Beneficial effects: When the surface of the cured self-leveling waterborne coating of the present invention is subjected to the bouncing impact pressure of the soles of high-weight moving personnel or other impact pressures, the discrete spherical arc surface top discs protruding on the surface of the self-leveling waterborne coating will be preferentially subjected to downward stamping. The downward impact pressure received by the spherical arc surface top disc is transmitted downward through the central column to the cured coating in the coating cage cavity of the bell-shaped cover. Since the cured coating filled in the coating cage cavity cannot be squeezed around under the surrounding restraint of the bell-shaped cover, the cured coating filled in the coating cage cavity forms a strong reaction force on the central column while not squeezing the part outside each coating cage cavity of the self-leveling waterborne coating, including the surface of the self-leveling waterborne coating, thereby avoiding possible shear and fatigue damage caused by squeezing on the surface and inside of the self-leveling waterborne coating, and thus achieving the anti-stamping performance of the surface of the self-leveling waterborne coating.

[0020] The present invention will be further described below with reference to the accompanying drawings.
[0021] As shown in the attached Figures 1 to 3 In a kind of anti-slip and impact-resistant self-leveling waterborne coating shown, a number of compressive, impact-resistant, anti-slip and scattering units 50 are evenly and discretely distributed in the self-leveling waterborne coating 60; the lower ends of each compressive, impact-resistant, anti-slip and scattering unit 50 are all in contact with the self-leveling base surface 9, and the upper ends of each compressive, impact-resistant, anti-slip and scattering unit 50 protrude in an arc shape above the surface of the self-leveling waterborne coating 60; the compressive, impact-resistant, anti-slip and scattering unit 50 is composed of a floating member 50a and a sinking member 50b combined; in the fluid state before the self-leveling waterborne coating 60 is cured, the floating member 50a floats to the top and protrudes above the surface of the self-leveling waterborne coating, and after the sinking member 50b sinks to contact the self-leveling base surface 9, the lower end of the floating member 50a and the upper end of the sinking member 50b still do not separate; the specific structure is as follows:
[0022] The floating member 50a includes a spherical arc surface top disc 1, the lower end of the spherical arc surface top disc 1 is integrally and coaxially connected with a central column 3, and there is a hollow chamber 2 inside the spherical arc surface top disc 1, making the floating member 50a have a light upper and heavy lower characteristic, and the comprehensive density of the floating member 50a is less than the density of the self-leveling waterborne coating 60 in the fluid state.
[0023] The sinking member 50b includes a bell-shaped cover 5, and a central column through-hole 7 is coaxially hollowed out at the top end of the bell-shaped cover 5; the central column 3 passes downward through the central column through-hole 7, and the outer wall of the central column 3 is in clearance fit with the inner wall of the central column through-hole 7.
[0024] A number of bubble overflow holes 4 are arranged in a circular array around the central column through-hole 7 at the upper end of the bell-shaped cover 5, and a thickened weight part 6 is arranged in a circle along the contour at the lower end of the bell-shaped cover 5. When there are bubbles in the emulsion in the bell-shaped cover 5, the bubbles gather at the top inside the bell-shaped cover 5 under the action of buoyancy, and thus overflow through the number of bubble overflow holes 4, so as to avoid the generation of bubbles inside the bell-shaped cover 5 subsequently.
[0025] When the compression-resistant, impact-resistant and anti-slip scattering unit 50 has not been scattered into the self-leveling water-based paint coating 60 in a fluid state, the upper end contour 5a of the bell-shaped cover 5 is adhered to the lower surface of the arc-shaped top plate 1 through a water-soluble adhesive. The water-soluble adhesive is a water-soluble phenolic resin, a polyvinyl alcohol adhesive, a starch-based adhesive, etc. When the compression-resistant, impact-resistant and anti-slip scattering unit 50 has been scattered into the self-leveling water-based paint coating 60 in a fluid state, the water-soluble adhesive at the adhesion place between the upper end contour 5a of the bell-shaped cover 5 and the lower surface of the arc-shaped top plate 1 is dissolved by the water or a liquid other than water in the self-leveling water-based paint coating 60 in a fluid state, so as to release the constraint of the water-soluble adhesive on the floating member 50a and the sinking member 50b; furthermore, the bell-shaped cover 5 sinks under the action of gravity until it contacts the self-leveling base surface 9, so that a paint cage cavity 91 filled with water-based paint is formed inside the bell-shaped cover 5. At the same time, the spherical arc-shaped top plate 1 floats up until the upper end protrudes out of the surface of the self-leveling water-based paint coating 60 in a fluid state. In this state, the lower end of the central column 3 is still sleeved in the central column through-hole 7, so that the lower end of the floating member 50a and the upper end of the sinking member 50b are still not separated at this time.
[0026] Both the floating member 50a and the sinking member 50b are made of a metal material, such as aluminum alloy.
[0027] Before the compression-resistant, impact-resistant and anti-slip scattering unit 50 is sown, both the height dimension and the width dimension are smaller than the thickness of the self-leveling water-based paint coating 60; the height dimension of the floating member 50a + the height dimension of the sinking member 50b is not less than the self-leveling water-based paint coating 60; in this case, the thickness of the self-leveling water-based paint coating 60 is 8 mm - 11 mm; both the height and width dimensions of the compression-resistant, impact-resistant and anti-slip scattering unit 50 before sowing are 6 mm - 7 mm; the height dimension of the bell-shaped cover 5 is 4 mm - 5 mm.
[0028] The paint emulsion ratio of the fluid uncured self-leveling waterborne paint coating 60 is as follows: 55-70 parts of polyurethane resin, 30-50 parts of filler, 35-45 parts of water, 16-20 parts of dimethylaminoethyl acrylate, 3-4 parts of diluent, 15-17 parts of curing agent, 2 parts of leveling agent, 2-9 parts of dispersant, and 0.5-1 part of defoamer.
[0029] The self-leveling process of the self-leveling waterborne paint coating:
[0030] Step 1, pour the self-leveling waterborne paint emulsion onto the self-leveling base surface 9 in the enclosed area. The emulsion self-levels under the action of gravity until the self-leveling thickness is 8 mm - 11 mm.
[0031] Step 2, evenly sprinkle a number of compressive, impact-resistant, and anti-slip sprinkling units 50 in a discrete state into the flowing self-leveling waterborne paint emulsion. During the falling process of each compressive, impact-resistant, and anti-slip sprinkling unit 50, under the action of gravity, the spherical arc surface top plate 1 of each compressive, impact-resistant, and anti-slip sprinkling unit 50 automatically tends to face upward because the inside is hollow and lighter.
[0032] When the compressive, impact-resistant, and anti-slip sprinkling units 50 fall into the self-leveling waterborne paint emulsion in a discrete state, the spherical arc surface top plate 1 of each discretely distributed compressive, impact-resistant, and anti-slip sprinkling unit 50 automatically faces upward because the inside is hollow and lighter, and the central column 3 of the solid part automatically faces downward.
[0033] Step 3, after standing for a certain period of time, about 1 h later, the water-soluble adhesive at the adhesion point between the upper end contour 5a of the bell-shaped cover 5 of each compressive, impact-resistant, and anti-slip sprinkling unit 50 and the lower surface of the arc surface top plate 1 is dissolved by the water or liquid other than water in the fluid state of the self-leveling waterborne paint emulsion, thereby releasing the constraint of the water-soluble adhesive on the floating member 50a and the sinking member 50b. Furthermore, the bell-shaped cover 5 of the compressive, impact-resistant, and anti-slip sprinkling unit 50 sinks under the action of gravity to contact the self-leveling base surface 9, and a paint cage cavity 91 filled with waterborne paint emulsion is formed inside the bell-shaped cover 5. At the same time, the spherical arc surface top plate 1 floats upward until the upper end protrudes from the surface of the fluid state of the self-leveling waterborne paint coating 60. In this state, the lower end of the central column 3 is still sleeved in the central column through hole 7, so that the lower end of the floating member 50a and the upper end of the sinking member 50b of each compressive, impact-resistant, and anti-slip sprinkling unit 50 at this time are still not separated. If there are air bubbles in the emulsion inside the bell-shaped cover 5 at this time, the air bubbles gather at the top inside the bell-shaped cover 5 under the action of buoyancy and then overflow through a number of air bubble overflow holes 4 to avoid generating air bubbles inside the bell-shaped cover 5 subsequently.
[0034] Step 4: The surface dries in about 8 hours and fully cures in 8 - 14 days. After curing, several spherical arc - surface top disks 1 exposed on the surface of the self - leveling water - based paint coating 60 are evenly distributed discretely. The discrete arc - spherical protrusions on the surface of the cured self - leveling water - based paint coating 60 play an anti - slip role. When the surface of the cured self - leveling water - based paint coating 60 is subjected to the bouncing impact pressure of the soles of high - weight moving personnel or other impact pressures, the discrete spherical arc - surface top disks 1 of the protrusions on the surface of the self - leveling water - based paint coating 60 will be preferentially subjected to downward stamping. The spherical arc - surface top disk 1 conducts the downward impact pressure received through the central column 3 to the cured paint in the paint cage cavity 91 of the bell - shaped cover 5. Since the cured paint filled in the paint cage cavity 91 cannot be squeezed around under the surrounding constraint of the bell - shaped cover 5, the cured paint filled in the paint cage cavity 91 forms a strong reaction force on the central column 3 without squeezing the part outside each paint cage cavity 91 of the self - leveling water - based paint coating 60, including the surface of the self - leveling water - based paint coating 60. Instead, the impact pressure from the soles of the moving personnel is directly transmitted to the self - leveling base surface 9 through the paint filled in the paint cage cavity 91, thus avoiding possible shear and fatigue damage caused by squeezing on the surface and inside of the self - leveling water - based paint coating 60, and achieving the anti - stamping performance of the surface of the self - leveling water - based paint coating 60.
[0035] The above are only the preferred embodiments of the present invention. It should be pointed out that for those of ordinary skill in the art of this technology, 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.
