Description
Technical Field
The invention relates to the technical field of floor coatings, in particular to an environment-friendly floor coating preparation process and preparation equipment.
Background
The traditional solvent type terrace paint contains about 50% of organic solvent, and a large amount of VOC can be emitted into the outside air during the manufacturing, construction, drying and curing and film forming processes of the paint, so that the environment is polluted. The solvent-free epoxy paint has no volatile organic solvent, is nontoxic and environment-friendly, and adopts epoxy resin with low relative molecular mass and reactive diluent as base materials. When in use, the solvent-free epoxy paint is uniformly mixed with a curing agent and cured into a film at room temperature or in the condition of heating and baking, so that the solvent-free epoxy paint not only has the excellent performance of the solvent-free epoxy paint, but also has higher film forming thickness and strong corrosion resistance.
For example, chinese patent publication No. CN114106656B discloses a solvent-free epoxy resin coating, and a preparation method and application thereof, wherein the solvent-free epoxy resin coating comprises a component A and a component B; the component A comprises the following raw materials: epoxy resin, single-walled carbon nanotubes, auxiliary agents and fillers; the component B is an amine curing agent.
Also for example, a garnet modified solvent-free epoxy floor coating disclosed in Chinese patent publication No. CN107163776B and a preparation method thereof, wherein the material consists of a component A and a component B, and the component A consists of low molecular weight liquid epoxy resin, an active diluent, a pigment, garnet, a leveling agent, a defoaming agent, a wetting dispersant and an anti-settling agent; the component B consists of modified alicyclic amine; and (3) filtering after the preparation of the component A is finished, and mixing the component A with the component B.
The floor coating comprises modified components such as single-wall carbon nanotubes or garnet, and the like, and the modified components are processed into particles, but still have the phenomenon of partial sinking due to the action of gravity in the process of mixing and stirring with other components. The rotary stirring in the main flow stirring device is difficult to drive deposited particles to move in a large range in the vertical direction, and centrifugal force is easy to generate in the stirring process to further collect the particles, so that the floor coating is generally stirred without adopting the rotary stirring device, and more swing arm type stirring devices are selected. The swing arm type stirring device drives the particles and the epoxy resin to generate displacement in the vertical direction through the vertical movement of the swing arm, and drives the particles and the epoxy resin to generate displacement in the horizontal direction through the horizontal movement of the swing arm, so that the particles and the epoxy resin are fully mixed. In the actual processing process, because particles and epoxy resin have inertia in the horizontal movement process, great impact force can be generated at the moment of impacting the inner wall of the stirring tank, and the tank body can be deformed or inclined due to long-term action. To avoid this, the volume in the stirred tank can only be reduced to reduce the inertia of the particles and epoxy resin in the tank, but this results in higher cost per unit of paint production; or the stirring speed of the swing arm is reduced to reduce the inertia of particles and epoxy resin, but the mixing effect of the coating is affected. Based on the above, how to fully mix particles and epoxy resin and ensure a large volume in the stirring tank to reduce the production cost of unit paint under the condition of avoiding the stirring tank from receiving a large impact force is a technical problem to be solved by the technicians in the field.

Detailed Description
In order to make the technical scheme of the present invention better understood by those skilled in the art, the present invention will be further described in detail with reference to the accompanying drawings.
Example 1
An environment-friendly floor coating preparation process comprises the following steps:
step one: uniformly stirring liquid epoxy resin and a diluent, then adding a dispersing agent and a defoaming agent in a divided manner, adding an anti-settling agent and garnet in the mixed state, and filtering to obtain a first component;
step two: adding 2773 curing agent into 2883 curing agent, and stirring to obtain a second component;
step three: mixing and stirring the first component and the second component to obtain the environment-friendly floor coating;
the first step is completed by adopting an environment-friendly floor coating preparation device, as shown in fig. 1 and 2, the environment-friendly floor coating preparation device comprises a stirring tank 1, a bottom plate 101 of the stirring tank 1 is arc-shaped, and two ends of the bottom plate 101 extend upwards to above a plane where a virtual circular center of the bottom plate is located; side plates 102 are fixedly arranged on two sides of the bottom plate 101; a discharge hole is arranged at the bottom of the bottom plate 101, the opening and the closing of the discharge hole can be controlled manually, a filter is arranged in the discharge hole, and the filter is used for filtering the materials stirred by the stirring tank 1; the discharge port and the filter are both of the prior art, and are not shown in the drawings of this embodiment, and are not described in detail herein; a horizontal shaft 2 coaxial with the virtual circle of the bottom plate 101 is rotatably arranged on the stirring tank 1, and a stirring assembly 3 is arranged on the horizontal shaft 2; the stirring assembly 3 swings synchronously along with the rotation of the horizontal shaft 2, the stirring assembly 3 is parallel to the side plates 102, and the end part of the stirring assembly 3 is attached to the upper surface of the bottom plate 101; the stirring member 3 in this embodiment includes a cylindrical portion fitted over the horizontal shaft 2 and a plate-like portion connected to the cylindrical portion.
During specific processing, the discharge port is closed firstly, then the liquid epoxy resin and the diluent are poured into the stirring tank 1, and the dispersing agent and the defoaming agent are added for a plurality of times, and the anti-settling agent and the garnet particles are added in the process; in the process, the horizontal shaft 2 always rotates reciprocally under the action of external force, so as to drive the stirring assembly 3 to swing reciprocally, and the swinging range of the stirring assembly 3 is shown as a double-headed arrow line in fig. 2; garnet particles are settled downwards under the action of gravity after entering the liquid epoxy resin and are collected at a position close to the bottom of the bottom plate 101; the stirring assembly 3 drives liquid epoxy resin and garnet particles to flow along the virtual circumference of the bottom plate 101 in the swinging process, and the garnet particles are fully mixed with the liquid epoxy resin in the reciprocating flow process; as can be seen from the swing path of the stirring assembly 3 in fig. 2, the flow path of the material in the stirring tank 1 pushed by the stirring assembly 3 does not directly vertically strike the bottom plate 101, but flows along the arc shape of the bottom plate 101, so that the impact force of the material on the stirring tank 1 is greatly reduced; in this way, the stirring tank 1 in this embodiment can accommodate more materials, and the stirring assembly 3 can also operate at a faster speed, so that even if the inertia of the materials in the stirring tank 1 is large, no large impact force is caused to the stirring tank 1.
It should be noted that in this embodiment, the faster the flow rate of the material in the stirring tank 1 is, the slower the flow rate of the material in the stirring tank is, and the speed difference exists between the materials with different flow rates, so that the radial flow along the virtual circle of the bottom plate 101 is generated by the materials, and then, garnet particles originally deposited at the bottom of the bottom plate 101 flow in an arc direction along the stirring assembly 3, and on the other hand, flow in a radial direction, thereby further promoting the thorough mixing of the liquid epoxy resin and garnet particles.
Example 2
As shown in fig. 3 and 4, this embodiment differs from the previous embodiment in that: in this embodiment, the stirring assembly 3 includes two swing arms 301 fixedly mounted on the horizontal shaft 2 and a plurality of guide rods 302 uniformly mounted between the two swing arms 301; the guide rods 302 are in a horizontal state, the two swing arms 301 are respectively positioned at two sides of the middle part of the horizontal shaft 2, and the distance between the swing arms 301 and the corresponding side plates 102 is not more than two centimeters; the cross section of the guide rod 302 is circular; specifically, the distance between two adjacent guide rods 302 is the same; in the synchronous swinging process of the two swing arms 301, each guide rod 302 synchronously moves along the swing arm 301, and the material in the stirring tank 1 passes through the area between the two adjacent guide rods 302 and flows along the surface of the guide rods 302 under the guide action of the guide rods 302 (shown by arrows in fig. 4); as can be seen from fig. 4, the materials flowing on the surface of the guide rod 302 collide with each other, so that irregular turbulence is formed behind the guide rod 302, which is equivalent to playing a further role in stirring, so as to further promote the mixing of the liquid epoxy resin and garnet particles in the materials.
In summary, in this embodiment, by setting the stirring component 3 to be in a hollow structure, on one hand, mixing of the liquid epoxy resin and garnet particles is further promoted, on the other hand, resistance applied to the stirring component 3 in the swinging process is also reduced, and energy consumption of the device is saved.
Example 3
As shown in fig. 5 and 7, this embodiment differs from the previous embodiment in that: in this embodiment, the flow guiding rod 302 includes an outer cylinder 3021 with an arc-shaped section and a rotating shaft 3022 coaxial with the outer cylinder 3021, and a plurality of rib rods 3023 are fixedly installed between the outer cylinder 3021 and the rotating shaft 3022; the rotating shaft 3022 penetrates through the swing arm 301 and is in running fit with the swing arm 301; specifically, in the process of synchronous swinging of the two swing arms 301, each guide rod 302 synchronously moves along the swing arm 301, and the material in the stirring tank 1 passes through the area between the two adjacent guide rods 302 and flows along the surface of the guide rod 302 under the guide action of the outer cylinder 3021; the materials flowing along the surface of the outer cylinder 3021 are irregularly diffused after mutually impacting, a part of the materials enter the inner side of the outer cylinder 3021 and further impact with the rib rods 3023, which is equivalent to stirring the materials again at the inner side of the outer cylinder 3021, and the liquid epoxy resin and garnet particles are mixed again at the inner side of the outer cylinder 3021, so that the full mixing of the materials is further promoted.
As shown in fig. 8, the end of the rotating shaft 3022 is fixedly provided with a gear 4, and the swing arm 301 is slidably provided with a rack 5 engaged with the corresponding gear 4; when the rack 5 moves, the rack drives each gear 4 meshed with the rack to rotate, and the gears 4 drive the rotating shaft 3022, the rib rods 3023 and the outer cylinder 3021 to synchronously rotate; then, as long as the swing arm 301 swings to the maximum amplitude and is stationary, the rack 5 can move a distance so that the outer cylinder 3021 rotates 180 °, then, no matter in which direction the swing arm 301 swings, the outer cylinder 3021 can be in contact with the front surface of the material on its closed side, that is, no matter in which direction the swing arm 301 swings, the material can flow along the surface of the outer cylinder 3021 and enter the inner side of the outer cylinder 3021 to collide with the rib 3023 for further mixing.
The driving manner of the rack 5 includes, but is not limited to, electric driving, i.e. an electric telescopic rod for driving the rack 5 to move is mounted on the swing arm 301, which is the prior art, and is not described herein.
As shown in fig. 6 and 9, the rack 5 is rotatably provided with a guide block 6, an elastic member 7 is connected between the guide block 6 and the rack 5, specifically, the elastic member 7 is not rotatable, the end of the elastic member 7 is provided with a round pin which is in rotation fit with the guide block 6, the round pin cannot be separated from the guide block 6, and the elastic member 7 is always in a compressed state; the side plate 102 is provided with a guide groove 103 matched with the guide block 6; the elastic force of the elastic piece 7 enables the guide block 6 to be always attached to the bottom of the guide groove 103 (in the embodiment, the bottom of the guide groove 103 is a vertical surface); the guide groove 103 comprises a first arc-shaped section 1031 and a second arc-shaped section 1032, and the first arc-shaped section 1031 and the second arc-shaped section 1032 are communicated with each other through a first connecting section 1033 and a second connecting section 1034; when the swing arm 301 swings, the gear 4, the rack 5 and the guide block 6 move synchronously along with the swing arm 301, and as illustrated in fig. 9, when the swing arm 301 swings anticlockwise, the guide block 6 is positioned in the first arc-shaped section 1031 and is in sliding fit with the first arc-shaped section 1031, and the rack 5 is positioned close to the horizontal shaft 2 and keeps a relatively static state with the swing arm 301; when the swing arm 301 swings anticlockwise to the maximum extent and swings clockwise, the guide block 6 firstly enters the first connecting section 1033 and then enters the second arc section 1032, and after the guide block 6 enters the second arc section 1032, the rack 5 is located at a position far away from the horizontal shaft 2 and keeps a relatively static state with the swing arm 301; when the swing arm 301 swings clockwise to the maximum extent and swings counterclockwise again, the guide block 6 firstly enters the second connection section 1034 and then returns to the first arc section 1031; the swing arm 301 continuously swings reciprocally, and the above process is repeated; the guide block 6 drives the rack 5 to move in the process of sliding in the first connection section 1033 and the second connection section 1034, so as to drive the outer cylinder 3021 to rotate 180 degrees, namely, drive the outer cylinder 3021 to perform reversing.
It should be noted that, in this embodiment, a step is formed at the connection position between the first arc-shaped section 1031 and the first connection section 1033, that is, the groove depth of the first connection section 1033 is greater than the groove depth of the connection position between the first arc-shaped section 1031 and the first connection section 1033, and the guide block 6 cannot directly return to the first arc-shaped section 1031 after entering the first connection section 1033 from the first arc-shaped section 1031; the junction of the second arc-shaped section 1032 and the second connecting section 1034 forms a step, that is, the groove depth of the second connecting section 1034 is greater than the groove depth of the junction of the second arc-shaped section 1032 and the second connecting section 1034, and the guide block 6 cannot directly return to the second arc-shaped section 1032 after entering the second connecting section 1034 from the second arc-shaped section 1032; the groove depth of the second arc-shaped section 1032 is consistent with the groove depth of the first connecting section 1033, the groove depth of the first arc-shaped section 1031 is in a gradual change state, and the groove depth of the first arc-shaped section 1031 near one end of the second connecting section 1034 is larger than the groove depth of the first arc-shaped section near one end of the first connecting section 1033; in this way, the guide block 6 is guaranteed to move cyclically along the track of the first arcuate segment 1031-the first connecting segment 1033-the second arcuate segment 1032-the second connecting segment 1034.
In summary, in the present embodiment, the materials flowing through the outer surface of the outer cylinder 3021 collide with each other and the materials collide with the rib 3023 for the second time, so as to promote the liquid epoxy resin and garnet particles to be fully mixed; the outer cylinder 3021 is indirectly reversed by the movement of the rack 5, so that the swing arm 301 swings in any direction, and the above effect can be achieved; and the automatic reversing of the outer cylinder 3021 can be realized by only driving the guide block 6 through the guide groove 103 without separately arranging a driving source for the rack 5.
Example 4
In the actual production process, if the amplitude of each swing of the stirring assembly 3 is constant, only a part of the swing stroke of the stirring assembly 3 is contacted with garnet particles deposited on the bottom of the bottom plate 101 in the initial stage of stirring, and most of the stroke is not contacted with garnet particles on the bottom of the bottom plate 101; specifically, only when the bottom end of the stirring assembly 3 is close to the bottom of the bottom plate 101, the stirring assembly 3 is contacted with garnet particles at the bottom of the bottom plate 101; based on this, the present embodiment is modified as follows.
As shown in fig. 13, on the basis of the above embodiment, the environmental-friendly floor paint preparation apparatus in this embodiment further includes a driving assembly 8 for driving the stirring assembly 3 to swing at different amplitudes, and the number of the first connection sections 1033 and the second connection sections 1034 is several; specifically, after the external feeding device inputs all garnet particles into the stirring tank 1, the driving component 8 drives the stirring component 3 to reciprocate with a smaller amplitude, the stirring component 3 is always contacted with the garnet particles deposited at the bottom of the bottom plate 101 in the whole swing stroke, and the garnet particles and the liquid epoxy resin are fully stirred and mixed; after stirring for a period of time, garnet particles and liquid epoxy resin are fully mixed in a small-range irregular sector area taking the vertical plane where the axis of the horizontal shaft 2 is positioned as a symmetrical plane, and the concentration of the garnet particles in the area is greater than that of garnet particles in materials in other areas in the stirring tank 1; then, the swing amplitude of the stirring assembly 3 is increased through the driving assembly 8; garnet particles and liquid epoxy resin are fully mixed in a larger irregular sector area taking the vertical plane where the axis of the horizontal shaft 2 is positioned as a symmetrical plane; the swing amplitude of the stirring assembly 3 is further increased through the driving assembly 8, and garnet particles and liquid epoxy resin are fully mixed in a larger irregular sector area taking the vertical plane where the axis of the horizontal shaft 2 is positioned as the symmetry plane; finally, the driving component 8 drives the stirring component 3 to stir at the maximum swing amplitude, and garnet particles and liquid epoxy resin are fully mixed in the irregular sector area with the maximum range of the vertical plane of the axis of the horizontal shaft 2 as the symmetry plane.
In summary, in the present embodiment, the swing amplitude of the stirring assembly 3 gradually increases, so that garnet particles deposited at the bottom of the bottom plate 101 gradually diffuse to two sides for mixing, and the stirring assembly 3 can always contact with the garnet particles in the swing stroke, thereby improving the stirring efficiency; because the number of the first connecting section 1033 and the second connecting section 1034 is multiple, when the stirring assembly 3 swings to the amplitude corresponding to the positions of the first connecting section 1033 and the second connecting section 1034, the outer barrel 3021 can perform 180-degree rotation reversing; it should be noted that, since the number of the first connection sections 1033 and the second connection sections 1034 is limited, but the variation of the oscillation amplitude of the stirring assembly 3 is continuous, the outer cylinder 3021 is not able to be commutated every time the stirring assembly 3 oscillates.
As shown in fig. 10, 11 and 12, the driving assembly 8 includes a swing seat 801 slidably mounted on the horizontal shaft 2 along the axial direction of the horizontal shaft 2, a sliding seat 802 slidably mounted on the swing seat 801 along the direction perpendicular to the axial direction of the horizontal shaft 2, and a ball 803 rotatably mounted on the sliding seat 802; a driving shaft 804 is rotatably arranged on each of the two side plates 102, the two driving shafts 804 are coaxial and fixedly provided with a rotating arm 805, and a round rod 806 penetrating through the sphere center of the round sphere 803 is fixedly connected between the two rotating arms 805; the drive assembly 8 further comprises a regulating unit for regulating the position of the oscillating seat 801 on the horizontal axis 2.
Specifically, in the axial static state of the swing seat 801 relative to the horizontal shaft 2, the driving shaft 804 is driven to rotate by external force, the driving shaft 804 drives the end of the round rod 806 to rotate by the rotating arm 805, and because the round rod 806 is not horizontal, that is, the round rod 806 is in an inclined state, when the two ends of the round rod 806 synchronously rotate, the round rod 806 drives the round ball 803 to revolve around the axis of the driving shaft 804, the round ball 803 drives the sliding seat 802 and the swing seat 801 to swing, the swing seat 801 synchronously drives the horizontal shaft 2 to reciprocally rotate, and the horizontal shaft 2 drives the stirring assembly 3 to reciprocally swing; when the swing seat 801 is located at the middle position of the horizontal shaft 2, the round ball 803 is also located at the middle position of the round rod 806, and the swing amplitude of the swing seat 801 and the stirring assembly 3 is minimum (tends not to swing); when the swing seat 801 moves towards the end position of the horizontal shaft 2, the ball 803 is driven to synchronously move towards the end position of the round rod 806; the sliding seat 802 moves relative to the swinging seat 801; when the driving shaft 804 is driven to rotate by external force, the amplitude of revolution of the round rod 806 driving the round ball 803 around the axis of the driving shaft 804 is increased, the amplitude of swing of the round ball 803 driving the sliding seat 802 and the swinging seat 801 is also increased, the angle of the swinging seat 801 driving the horizontal shaft 2 to reciprocate is increased, and the amplitude of the horizontal shaft 2 driving the stirring assembly 3 to reciprocate is increased; then, the swing amplitude of the stirring assembly 3 can be synchronously controlled as long as the position of the swing seat 801 on the horizontal shaft 2 is controlled by the regulating and controlling unit.
As shown in fig. 13, the regulating unit includes an arc-shaped guide rail 807 fixedly mounted on one of the side plates 102, a support block is slidably mounted on the arc-shaped guide rail 807, a screw 808 is rotatably mounted on the support block, and the screw 808 penetrates through the swing seat 801 in a threaded fit manner; a motor 809 for driving the screw 808 to rotate is arranged on the supporting block; when the swing seat 801 swings reciprocally, the lead screw 808, the supporting block and the motor 809 are driven to swing synchronously, and the supporting block slides reciprocally in the arc-shaped guide rail 807; the motor 809 drives the screw 808 to rotate, and the screw 808 can drive the swing seat 801 to axially move on the horizontal shaft 2.
In this embodiment, as shown in fig. 10, the two rotating arms 805 are identical in shape and size, and when the ball 803 is located in the middle of the round rod 806, the swing seat 801 is also located in the middle of the horizontal shaft 2, and the swing amplitude of the stirring assembly 3 is minimal and tends not to swing.
As shown in fig. 10, in this embodiment, a wiper 810 is fixedly mounted on the sliding seat 802, the wiper 810 is parallel to the swing arm 301, and each outer cylinder 3021 penetrates the wiper 810 and is in running fit with the wiper 810; during the axial movement of the swinging seat 801 on the horizontal shaft 2, the scraping strip 810 scrapes the outer wall of the outer barrel 3021 on one hand, so that garnet particles are prevented from adhering to the outer wall of the outer barrel 3021, and the materials in the stirring tank 1 are transversely stirred on the other hand, and the mixing of the materials is further promoted.
While certain exemplary embodiments of the present invention have been described above by way of illustration only, it will be apparent to those of ordinary skill in the art that modifications may be made to the described embodiments in various different ways without departing from the spirit and scope of the invention. Accordingly, the drawings and description are to be regarded as illustrative in nature and not as restrictive of the scope of the invention, which is defined by the appended claims.
