Background
In daily life and industrial production, the friction coefficient of the surface of an object is reduced in a humid environment, people or objects are prone to sliding, for example, when a bathroom bottom plate and a wall surface are prone to falling down and endangering the health of people, and for example, when the object price is placed on the periphery of a wash basin, objects are prone to sliding down and causing property loss, and for example, when the bottom plate of a public toilet is prone to sliding down and endangering the health of people, the objects are prone to falling down and endangering the health of people.
At present, in the market, there are ways to improve the anti-skid performance of the coating, for example, an anti-skid powder coating and an on-line coating method thereof described in patent CN110982376A, the anti-skid capability of the coating is improved by the principle of increasing the roughness of the surface of the coating; for another example, CN104710926A discloses a SiC fiber reinforced polyurethane-based anti-slip coating and a preparation method thereof, which can improve the anti-slip capability of the coating by improving the friction coefficient of the surface of the coating.
However, the above anti-slip principle has certain disadvantages in a humid environment, for example, a large amount of water may significantly reduce the friction coefficient, thereby making the anti-slip property of the coating ineffective.
Disclosure of Invention
The invention aims to provide a feasible powder coating which can provide excellent anti-skid performance under dry and wet environments, a preparation method and a coating process thereof.
In order to achieve the technical purpose, the invention adopts the following technical scheme: the anti-skid powder coating consists of base powder and flour; the base powder comprises the following raw materials in percentage by weight: epoxy resin: 50.0 to 65.0 percent; curing agent: 2.5 to 17.0 percent; modified TPU resin: 10.0 to 20.0 percent; sand streak agent: 0.5% -1.0%; benzoin: 0.1 to 0.3 percent; pigment: 3.0 to 25.0 percent; filling: 0 to 27.0 percent; the sum of the percentages is 100 percent; the flour consists of the following raw materials in percentage by weight: TPU resin: 60 to 90 percent; nano silicon dioxide: 0.5% -1.0%; water: 1.0-5.0%; pigment: 3.0 to 25.0 percent; filling: 0 to 26.0 percent; the sum of the percentages is 100%.
The invention also provides a preparation method for preparing the anti-skid powder coating, which comprises the following steps:
(1) weighing raw materials according to the formula percentage; after the temperature of the double-screw extruder is raised to a preset first temperature value, carrying out melt extrusion, cooling and tabletting, coarse crushing, ACM grinding and crushing, and grading to obtain bottom powder with the average particle size of 25-45 mu m; (2) weighing raw materials of flour according to the formula percentage, and carrying out melt extrusion, cooling tabletting and water-cooling coarse crushing when the temperature of a single-screw extruder is raised to a preset second temperature value; and grinding by using ACM at a preset third temperature value, and grading to obtain flour powder with the average particle size of 15-20 mu m.

Compared with the traditional antiskid powder coating, the invention has the following advantages:
1. 1-5% of water is added into the flour formula, when the powder coating is baked, the water is volatilized, so that a flour layer of the coating is loose and porous, in addition, a spraying surface is placed in parallel with the ground when the powder coating is baked, and the TPU resin is softened by utilizing gravity and high temperature to grow a protruded columnar coating vertical to a substrate. In the using process of the coating, the raised column shape in a dry environment and the elasticity of the TPU material can provide excellent anti-skid performance, in a wet environment, the surface of the loose porous elastic flour coating generates a capillary phenomenon to absorb a large amount of liquid, when a human body or an object applies force to the coating, the coating is squeezed, the absorbed liquid is discharged, a local pressure difference is generated, and the person or the object applying the force is sucked, so that the anti-skid effect is achieved;
2. the nano silicon dioxide in the flour formula plays a role in helping the dispersion of the pigment and the TPU resin, more importantly, the TPU resin is helped to absorb and lock water in the formula, the volatilization of water in the extrusion process of raw materials is reduced, and a loose and porous coating is helped to be formed;
3. the base powder adopts an epoxy resin system, and the excellent corrosion resistance of the base powder is utilized to make up the defect that the base material cannot be completely protected if the flour is directly coated on the base material due to looseness and porosity;
4. the matched powder preparation process is designed according to the uniqueness of the formula, compared with epoxy resin, TPU resin has high melting point and high viscosity, a double-screw extruder is required for extruding and mixing bottom powder, and the mixing effect is better; the flour formula has high TPU resin content, needs higher temperature, adopts a single-screw extruder to provide better dispersion during extrusion, can be crushed only below the embrittlement temperature of the TPU resin when being crushed into powder, and can provide ultralow-temperature crushing at 40-100 ℃ by adopting liquid nitrogen crushing and grading.
5. The average grain diameter of the flour powder coating designed by the invention is 15-20 mu m, and a fine columnar coating can be generated when the powder is baked, so that a capillary phenomenon is generated;
6. the matched coating process provided by the invention adopts a baking mode that two coatings and one baking are carried out, and the spraying surface is parallel to the ground, so as to form the columnar coating.

In the embodiment, the flour proportion of the sample powder 1 and the sample powder 2 is completely the same; the sample powder 1 and the sample powder 2 are different in that in the sample powder 1, the base powder contains modified TPU resin, and the weight ratio is 15%; sample powder 2 had no modified TPU resin.
In the present invention, the epoxy resin includes one or more of bisphenol a type epoxy resin, phenol-modified epoxy resin, hydrogenated or brominated bisphenol a epoxy resin, alicyclic glycidyl ether type epoxy resin, and alicyclic glycidyl ester type epoxy resin.

2) weighing raw materials according to the formula percentage of the base powder of the sample powder 2, and carrying out melt extrusion, cooling tabletting, coarse crushing and ACM grinding classification when a double-screw extruder is heated to 100 ℃ to obtain the base powder of the sample powder 2 with the average particle size of 30 mu m;

In this embodiment, the spraying of the anti-slip powder coating on the surface of the metal substrate is performed, and the coating process of the sample powder 1 is the same as that of the sample powder 2, and includes the following steps:
(a) respectively spraying base powder of the sample powder 1 and base powder of the sample powder 2 prepared in the steps (1) and (2) on the surface of the pretreated metal substrate in an electrostatic spraying manner to obtain a semi-finished workpiece 1 and a semi-finished workpiece 2 for later use;
(b) b, spraying flour on the surfaces of the semi-finished workpiece 1 and the workpiece 2 respectively for later use in an electrostatic spraying mode on the basis of the step a;

(d) the sprayed surface of the metal substrate was baked in an oven at 210 ℃ for 15min to obtain samples 1 and 2. The spraying surface of the metal substrate is placed in parallel with the horizontal ground in the placing process.
The above sample powders 1 and 2 were tested to give comparative table 1:
comparative Table 1
As can be seen from the above table, the base powder formulation of sample powder 2 does not contain a modified TPU resin; therefore, after the base powder and the flour of the sample powder 2 are baked, the bonding force between the coatings is reduced; the sample powder 1 is added with the modified TPU resin, and the binding force between the coating layers is very firm after the base powder and the flour are baked. Particularly, after the accelerated test simulating the long-term performance, the results of the sample powder 1 and the sample powder 2 are obviously different, and the conclusion is further confirmed.
The second embodiment is as follows:
in this example, a sample powder of an anti-slip powder coating was prepared,
sample powder 3: the base powder comprises the following raw materials in percentage by weight:
epoxy resin: 55 percent of
Curing agent: 5 percent of
Modified TPU resin: 15 percent of
Sand streak agent: 0.7 percent
Benzoin: 0.2 percent of
Pigment: 10 percent of
Filling: 14.1 percent;
the flour consists of the following raw materials in percentage by weight:
TPU resin: 75 percent;
nano silicon dioxide: 0.75 percent;
pigment: 12 percent;
filling: 12.25 percent.
In this example, the preparation process of the anti-slip powder coating is as follows:
1) weighing raw materials according to the formula percentage of the base powder of the sample powder 3, and carrying out melt extrusion, cooling tabletting, coarse crushing and ACM grinding classification when a double-screw extruder is heated to 108 ℃ to obtain the base powder of the sample powder 3 with the average particle size of 30 mu m;
2) weighing the raw materials of the flour of the sample powder 3 according to the formula percentage, carrying out melt extrusion, cooling and tabletting, water cooling and coarse crushing when a single-screw extruder is heated to 190 ℃, and carrying out ACM grinding and classification at the temperature of 40-100 ℃ below zero of a third temperature value to obtain the flour powder with the average particle size of 18 mu m.
In this embodiment, the spraying process of the anti-slip powder coating is the same as that in the first embodiment; sample 3 was obtained by spraying sample powder 3 on the surface of a metal substrate by a spray coating process.
For sample 3 above and sample 2 in example one, a comparative table 2 is obtained:
| sample 1 | Sample 3 | |
| Appearance of the product | Roughness of | Is relatively coarse |
| Water absorption | 80％ | 1％ |
Comparative Table 2
As can be seen from the above table, no water was added to the flour formulation of sample flour 3; after spraying, the coating cannot be loosened and porous, so that the water absorption capacity is obviously reduced, and therefore, the condition of capillary phenomenon cannot be formed.
The third concrete embodiment:
in this example, a sample powder of an anti-slip powder coating was prepared,
sample powder 4: the base powder comprises the following raw materials in percentage by weight:
epoxy resin: 55 percent of
Curing agent: 5 percent of
Modified TPU resin: 15 percent of
Sand streak agent: 0.7 percent
Benzoin: 0.2 percent of
Pigment: 10 percent of
Filling: 14.1 percent;
the flour consists of the following raw materials in percentage by weight:
TPU resin: 75 percent;
nano silicon dioxide: 0.75 percent;
water: 3.0 percent;
pigment: 12 percent;
filling: 9.25 percent.
In this example, the formulation of the sample powder 4 is completely the same as the formulation of the sample powder 1 in the first embodiment.
In this example, the preparation process of the anti-slip powder coating of sample powder 4 is as follows:
1) weighing raw materials according to the formula percentage of the base powder of the sample powder 4, and carrying out melt extrusion, cooling tabletting, coarse crushing and ACM grinding classification when a double-screw extruder is heated to 108 ℃ to obtain the base powder of the sample powder 4 with the average particle size of 30 mu m;
2) weighing the raw materials of the base powder of the sample powder 4 according to the formula percentage, and carrying out melt extrusion, cooling tabletting, coarse crushing, ACM grinding and grading when the temperature of a double-screw extruder is raised to 100 ℃ to obtain the base powder of the sample powder 2 with the average particle size of 30 mu m.
It can be seen that during the preparation process, the flour average particle size of the flour 4 was 30 μm, while the flour average particle size of the flour 1 was 18 μm.
In this embodiment, the sample powder 4 is the same as the sample powder 1 in the first embodiment. Sample 4 was obtained by spraying sample powder 4 on the surface of a metal substrate by a spray coating process.
The above sample 4 and the sample 1 in the first embodiment were compared to obtain a comparison table 3:
| sample 1 | Sample No. 4 | |
| Appearance of the product | Roughness of | Large particle |
| Water absorption | 79％ | 53％ |
| Surface adsorption force | 0.98N | 0.02N |
Comparative Table 3
From the above comparative table 3, it can be seen that when the average grain size of the flour of the sample powder 4 is 30 μm, the water absorption and the adsorption force to the object are reduced remarkably, the surface is changed from rough to large, the diameter of the columnar TPU coating is too thick, the capillary effect is weakened, the water absorption is reduced, and the pressure difference generated when the coating is extruded is reduced, and the surface adsorption force is reduced.
The fourth concrete embodiment:
in this example, the same formulation and the same preparation method as those of the sample powder 1 in the first embodiment were adopted; when coating is carried out on the surface of a metal substrate, the following spraying process is adopted:
(a) spraying base powder of the sample powder 4 on the surface of the pretreated metal substrate in an electrostatic spraying manner to obtain a semi-finished workpiece 5 for later use;
(b) on the basis of the step a, spraying flour on the surface of the semi-finished workpiece 5 in an electrostatic spraying manner for later use;
(c) on the basis of the step b, repeating the step (a) and the step (b) on the spraying surface of the semi-finished workpiece 5, namely, spraying the surface of the metal substrate twice;
(d) placing the sprayed surface of the metal substrate in an oven at the temperature of 210 ℃ for baking for 15min to obtain a sample 5; in the placing process, the spraying surface of the metal substrate is vertical to the horizontal ground.
As can be seen from the above spraying process, in this embodiment, after the surface of the metal substrate is sprayed, the metal substrate is placed in an oven, and the spraying surface of the metal substrate is perpendicular to the horizontal ground; in one embodiment, the spraying surface of the metal substrate is arranged at a horizontal angle with the horizontal ground. Thus, comparative table 4 is derived:
| sample 1 | Sample No. 5 | |
| Appearance of the product | Roughness of | Is smoother |
| Water absorption | 82％ | 3％ |
| Surface adsorption force | 0.99N | 0N |
Comparative Table 4
As can be seen from the above table, in sample 5, by changing the angle of the sprayed surface when the workpiece is baked, compared with sample 1, the appearance is obviously flat, which indicates that there are fewer pillars formed by the coating, the water absorption is reduced, and the capillary phenomenon is reduced, thereby resulting in a reduction in the surface adsorption force.
It can be demonstrated through specific examples 1-4 that in the present invention, the formulation, preparation process and coating process of the anti-slip powder coating are all synergistic and cross each other, and the design of each parameter is set for achieving the effect of the coating, and the effect is very significant.
Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
