Description

Technical Field

[0001] The present invention relates to the technical field of antifouling coatings, and specifically to a high-performance antifouling coating for ship hulls and its spraying equipment. Background Art

[0002] In marine engineering equipment mainly including ships, due to the influence of seawater and marine microorganisms, it is mostly necessary to spray an additional layer of antifouling coating on the basic coating on the outer hull of the ship to prevent a large amount of impurities from adhering to the hull, which affects the service life of the hull. At the same time, when spraying the antifouling coating, it is mostly manually sprayed in cooperation with a crane device. However, the existing antifouling coatings and their spraying equipment have the following problems when in use:

[0003] Regarding the antifouling coating, when the traditional antifouling coating is based on cold-sprayed zinc for protection, most of its zinc powder is below 500 mesh, resulting in poor rust removal and salt spray resistance, which affects its antifouling ability for the hull. At the same time, when spraying, it mostly requires multi-component on-site mixing and spraying. Since the proportions of each component are different, it is not convenient to perform real-time quantitative mixing. When directly poured together for mixing, it takes a long time. When manually spraying a large area on a crane, it needs to be mixed and used multiple times, which wastes time and affects the spraying efficiency.

[0004] In view of the above problems, there is an urgent need to innovate and design on the basis of the original antifouling coatings and their spraying equipment. Summary of the Invention

[0005] The purpose of the present invention is to provide a high-performance antifouling coating for ship hulls and its spraying equipment to solve the problems of poor rust removal and salt spray resistance of the existing antifouling coatings and their spraying equipment, and the inconvenience of real-time quantitative mixing during spraying.

The ratio of hydroxy acrylic emulsion or resin, water, defoamer, film-forming aid, wetting agent, thickener, rust inhibitor, and aluminum silver paste in component B is 23% - 25%, 2% - 4%, 0.1%, 1% - 2%, 0.1%, 0.1% - 0.5%, 0.5%, and 1% - 2%.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] 1. In the present invention, by using a water - borne isocyanate curing agent to cooperate with a hydroxyl acrylic emulsion or resin to generate a cross - linking reaction, the adhesion and hardness are improved. When adding zinc powder with a mesh size of 500 - 1500 meshes, while achieving high rust - removal and salt - fog resistance performance, the strength of the product can be improved, thereby improving the anti - fouling performance of the anti - fouling paint.

[0022] 2. In the present invention, a quantitative feeding component is provided. The material bottles containing three-component raw materials are respectively fixed on the feeding hopper. When the stirring rod is driven to rotate by the motor, the piston plate can be driven to move up and down. Through the cooperation of the blocking ball and the conveying cavity, the raw materials in the material bottle can enter the upper part of the piston plate unidirectionally, and at the same time, the raw materials above the piston plate can enter the mixing barrel unidirectionally. By correspondingly setting the sizes of the three blocking balls, quantitative feeding of the three-component raw materials is achieved. At the same time, in cooperation with the repeated up-and-down movement of the piston plate, the raw materials can be mixed in real time, avoiding the increase in time caused by unified mixing, enabling the raw materials to be sprayed while being mixed, and greatly improving the spraying efficiency.

[0023] 3. In the present invention, a distance adjustment component is provided. During use, the contact rod is abutted against the hull. The upper and lower contact rods are adjusted in real time according to the inclination angle of the hull. The infusion tube and the nozzle can be driven to move synchronously by the contact rod, so that the nozzle can always maintain a relative position with the hull. Further, through the setting of the adjusting plate, when the infusion tube moves horizontally, the up-and-down angle can be adjusted, enabling the nozzle to correspond to the position of the hull while also corresponding to the angle of the hull. On the one hand, positioning spraying can be carried out by the contact between the contact rod and the hull. On the other hand, although there will be shaking when holding the spray gun and moving it, the nozzle can still maintain its position relative to the hull. In traditional technologies, mostly manual experience is relied on to control the distance, and the distance between the nozzle and the hull is likely to be too close or too far. Moreover, traditional nozzles spray in a scattered manner, and both the change in distance and the change in angle are factors affecting the spraying uniformity.

[0024] 4. In the present invention, a swinging component and a pushing component are provided. As the spraying progresses, the mounting seat moves together, which can drive the second rack to move synchronously. At the same time, the mounting seat drives the T-shaped rod to move. Under the conduction of the oil pipe and the oil guide ring, the elastic force of the spring is used to drive the pushing block to move synchronously. Furthermore, when the mounting disk is driven to rotate by the power of the stirring rod, the pushing block can push the second rack to move, driving the infusion tube to swing reciprocally, realizing reciprocating spraying, increasing the spraying range, and avoiding the discomfort of the hand caused by repeatedly turning the wrist when holding the spray gun by hand. During this process, while adjusting the position of the nozzle according to the holding position, the movement of the mounting seat, in cooperation with the use of the pushing component, enables the swinging amplitude of the nozzle to remain constant and not be affected by the horizontal movement of the nozzle, improving the convenience of equipment use.

[0042] By using the distance adjustment component 14, when a worker holds the spray gun seat 1, by abutting the contact rod 143 against the hull, the position of the nozzle 10 is adjusted synchronously, so that the nozzle 10 always maintains a corresponding position and angle with the hull, improving the spraying uniformity.

[0043] Example Four, please refer to Figures 1-3 and Figures 8-9, the swing assembly 15 is arranged on the right side of the mounting seat 6, and the swing assembly 15 is used to push the infusion tube 9 to swing reciprocally; the pushing assembly 16, the pushing assembly 16 is arranged in the spray gun seat 1, and the pushing assembly 16 is used to realize the movement of the swing assembly 15; the swing assembly 15 includes a third elastic telescopic rod 151, and the third elastic telescopic rod 151 is fixed inside the mounting seat 6, and the end of the third elastic telescopic rod 151 is connected with a second rack 153 through a connecting rod 152, and a swing gear roller 154 is engaged on the side of the second rack 153, and the swing gear roller 154 is fixed on the shaft rod between the mounting seat 6 and the mounting frame 8; the pushing assembly 16 includes a T-shaped rod 161, and the T-shaped rod 161 is fixed inside the mounting seat 6, the right end of the T-shaped rod 161 is slidably arranged in the first oil chamber 162 in a fitting manner, and the first oil chamber 162 is opened in the oil seat 163, and the oil seat 163 is fixed inside the spray gun seat 1, the first oil chamber 162 is connected with an oil guide ring 165 through an oil pipe 164, and the oil guide ring 165 is rotatably arranged in a fitting manner in the second oil chamber 166, and the second oil chamber 166 is opened on the mounting disc 167, the mounting disc 167 is sleeved on the large gear roller 168, and a small gear roller 169 is engaged on the right side of the large gear roller 168, and both the small gear roller 169 and the large gear roller 168 are rotatably arranged in the spray gun seat 1, the small gear roller 169 is connected with the stirring rod 5 through a belt, a telescopic cavity 1610 is opened on the outer side of the mounting disc 167, and a pushing block 1612 is connected in a fitting manner in the telescopic cavity 1610 through a spring 1611, and the telescopic cavity 1610 is communicated with the second oil chamber 166; the left end of the pushing block 1612 is designed as an arc structure, and the left end of the pushing block 1612 corresponds to the right end position of the second rack 153;

[0044] By using the swing assembly 15, the reciprocating swing of the nozzle 10 can be realized, the spraying area can be increased, and at the same time, the trouble of manually turning the wrist can be avoided. Further, by using the pushing assembly 16, no matter how the position of the nozzle 10 is adjusted, the nozzle 10 can maintain a constant swing amplitude.

[0045] Working principle: When using the high-performance antifouling paint for ship hulls and its spraying equipment, such as Figures 1-9Among them, first, the worker rotates and inserts the material bottle 31 filled with three-component raw materials into the corresponding cavity on the material conveying hopper 3, and starts the motor 4. The motor 4 drives the piston plate 131 to move up and down through the stirring rod 5. When the piston plate 131 moves downward, a negative pressure is generated in the top area of the piston plate 131. At this time, the blocking ball 135 at the bottom of the material bottle 31 is forced to move downward, so that the conveying cavity 132 at the bottom of the material bottle 31 is opened. According to the space ratio of the conveying cavities 132 at the bottoms of the three material bottles 31, the materials in the three material bottles 31 are proportionally sucked into the area above the piston plate 131. When the piston plate 131 moves upward, the blocking ball 135 at the bottom of the material bottle 31 loses the negative pressure, and under the action of the first elastic telescopic rod 134, the blocking ball 135 resets to block the conveying cavity 132 again. At this time, the material no longer drops. With the repeated up and down movement of the piston plate 131, the materials in the three material bottles 31 are proportionally sucked above the piston plate 131. When the piston plate 131 moves upward, the materials above it are squeezed, so that the blocking ball 135 in the piston plate 131 moves downward, and the materials are guided into the mixing barrel 2. The stirring rod 5 in the mixing barrel 2 stirs the quantitatively exported materials in real time. At the same time, the conveying pump 12 is started, and the mixed materials are conveyed through the pipe fittings to the infusion pipe 9 and sprayed out by the nozzle 10. The material bottle 31 is made of transparent material, so that the worker can observe the material content in the material bottle 31 in real time, which is convenient for timely replacing the corresponding new material bottle 31;

[0046] When spraying, the worker holds the spray gun seat 1, and the roller at the end of the contact rod 143 abuts against the hull. The contact rod 143 moves under force and drives the main gear 144 and the auxiliary gear 145 to rotate through the first rack 142. Then, it drives the mounting seat 6 to move by meshing with the tooth block 146. The mounting seat 6 is limited and slides on the guide rail in the spray gun seat 1 through the positioning rod 7 to keep the stable movement of the mounting seat 6. Under the conduction of the main gear 144 and the auxiliary gear 145, the mounting seat 6 and the contact rod 143 move synchronously and in the same direction, and then drive the mounting frame 8, the infusion pipe 9 and the nozzle 10 to move synchronously, so that the position of the nozzle 10 and the position of the end of the contact rod 143 always maintain a constant distance. Furthermore, the nozzle 10 can maintain a constant distance from the hull, improving the spraying uniformity of the disc. At the same time, when the infusion pipe 9 moves, through its elastic rotation on the mounting frame 8 and in cooperation with the use of the adjusting plate 11, the infusion pipe 9 adjusts the up and down angles synchronously when moving, keeping the angle with the hull;

[0047] When the mounting seat 6 is stressed and moves, the third elastic telescopic rod 151 and the connecting rod 152 drive the second rack 153 to move synchronously, keeping the position of the second rack 153 relative to the swing tooth roller 154. Meanwhile, the mounting seat 6 drives the T-shaped rod 161 to move rightward in the first oil chamber 162, increasing the oil storage space inside the first oil chamber 162. Under the action of the spring 1611, the pushing block 1612 moves inward accordingly. The excess oil in the telescopic chamber 1610 is squeezed into the extra space in the first oil chamber 162 through the second oil chamber 166 and the oil pipe 164, so that the pushing block 1612 can maintain a constant position relative to the second rack 153. The stirring rod 5 drives the small tooth roller 169 to rotate, which can drive the large tooth roller 168 to rotate, and then drive the mounting disc 167 to rotate on the oil guiding ring 165, maintaining the smoothness of the oil flow path. The rotation of the mounting disc 167 can drive the pushing block 1612 to rotate. The arc-shaped structure at the end of the pushing block 1612 contacts the second rack 153. In cooperation with the use of the third elastic telescopic rod 151, it pushes the second rack 153 to move reciprocally. Through the meshing of the second rack 153 with the swing tooth roller 154, it drives the mounting frame 8 to rotate horizontally, and then drives the infusion tube 9 to swing reciprocally for large-area automatic spraying horizontally.
