Technical Field

[0001] This utility model relates to the field of waterborne acrylic modified polyurethane preparation technology, specifically to a temperature control device for the preparation of waterborne acrylic modified polyurethane. Background Technology

[0002] Waterborne acrylic-modified polyurethane (PUA) is a composite emulsion that combines the flexibility of polyurethane (PU) with the hardness and weather resistance of acrylic ester (PA) through graft copolymerization. It is widely used in coatings, adhesives and other fields. Combining the weather resistance and gloss of acrylic resin with the abrasion resistance and adhesion of polyurethane, it has excellent comprehensive performance.

[0003] Currently, the preparation of waterborne acrylic modified polyurethane involves the use of reaction equipment for processing and reaction. However, the reaction of waterborne acrylic modified polyurethane requires multiple heating and cooling cycles. The temperature control devices on existing reaction equipment cannot achieve frequent and rapid heating and cooling. Therefore, a temperature control device for the preparation of waterborne acrylic modified polyurethane is proposed. The device controls the opening of the first solenoid valve through a temperature controller, allowing high-temperature steam to flow into the annular coil. The temperature controller also controls the closing of the first solenoid valve and the opening of the second solenoid valve, allowing cooling water to flow into the annular coil, thus achieving frequent and rapid heating and cooling. Utility Model Content

[0004] To address the problems in the existing technology, this utility model provides a temperature control device for the preparation of waterborne acrylic modified polyurethane. The device controls the opening of the first solenoid valve through a temperature controller, allowing high-temperature steam to flow into the annular coil. The device also controls the closing of the first solenoid valve and the opening of the second solenoid valve through the temperature controller, allowing cooling water to flow into the annular coil. This enables frequent and rapid heating and cooling.

[0005] The technical solution adopted by this utility model to solve its technical problem is a water-based acrylic modified polyurethane preparation temperature control device, including a stainless steel ring, a temperature controller and a liquid inlet pipe. A heat-conducting plate is provided inside the stainless steel ring, and an annular coil is embedded inside the heat-conducting plate. A temperature controller is provided on one side of the stainless steel ring, and a liquid inlet assembly is provided on the other side of the stainless steel ring.

[0006] The liquid inlet assembly includes a connecting pipe, one end of which is welded with a tee pipe, and the two ends of the tee pipe away from the connecting pipe are respectively connected to a first solenoid valve and a first solenoid valve through threaded grooves.

[0007] By adopting the above technical solution, the first solenoid valve is opened to allow high-temperature steam to flow into the annular coil, and the water-based acrylic modified polyurethane in the reaction equipment is heated through the heat-conducting plate. The first solenoid valve is closed and the second solenoid valve is opened to allow cooling water to flow into the annular coil, and the water-based acrylic modified polyurethane is cooled through the heat-conducting plate.

[0008] Specifically, the inlet and outlet ends of the annular coil located on the outside of the stainless steel ring are respectively connected to an inlet pipe and an outlet pipe via pipe joints.

[0009] Specifically, a thermometer is connected to the top of the connecting pipe via a threaded groove, and the end of the connecting pipe away from the tee pipe is fixed to one end of the inlet pipe via a flange.

[0010] Specifically, the temperature sensor is fixed to the signal input terminal of the temperature controller by bolts, and there are two sets of temperature sensors.

[0011] Specifically, the heat-conducting plate is made of graphene material.

[0012] The beneficial effects of this utility model are:

[0013] The present invention discloses a temperature control device for the preparation of waterborne acrylic modified polyurethane. After the first solenoid valve is opened, high-temperature steam circulates in the annular coil and heats the waterborne acrylic modified polyurethane in the reaction equipment through the heat-conducting plate. When the first solenoid valve is closed, the second solenoid valve is opened, allowing cooling water to circulate in the annular coil and cool the heat-conducting plate that has absorbed the heat from the waterborne acrylic modified polyurethane. This allows for frequent and rapid heating and cooling of the waterborne acrylic modified polyurethane. Attached Figure Description

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] The thermostat controls the opening of the first solenoid valve, allowing high-temperature steam to flow into the annular coil. The thermostat also controls the closing of the first solenoid valve and the opening of the second solenoid valve, allowing cooling water to flow into the annular coil. This enables frequent and rapid heating and cooling. Figure 1-3 As shown, the waterborne acrylic modified polyurethane preparation temperature control device of this utility model includes a stainless steel ring 1, a temperature controller 2 and a liquid inlet pipe 6. A heat-conducting plate 4 is provided inside the stainless steel ring 1, and an annular coil 5 is embedded inside the heat-conducting plate 4. A temperature controller 2 is provided on one side of the stainless steel ring 1, and a liquid inlet assembly 3 is provided on the other side of the stainless steel ring 1.

[0021] The liquid inlet assembly 3 includes a connecting pipe 301, one end of which is welded with a three-way pipe 302. The two ends of the three-way pipe 302 away from the connecting pipe 301 are respectively connected to a first solenoid valve 304 and a first solenoid valve 304 through threaded grooves.

[0022] In use, the first solenoid valve 304 is opened to allow high-temperature steam to flow into the annular coil 5, and the water-based acrylic modified polyurethane in the reaction equipment is heated through the heat-conducting plate 4. The first solenoid valve 304 is closed and the second solenoid valve 305 is opened to allow cooling water to flow into the annular coil 5, and the water-based acrylic modified polyurethane is cooled through the heat-conducting plate 4.

[0023] For example, such as Figure 2 As shown, the present invention also includes an inlet pipe 6 and an outlet pipe 7 respectively connected to the inlet end and outlet end of the annular coil 5 located outside the stainless steel ring 1 via pipe joints.

[0024] During use, the inlet pipe 6 and outlet pipe 7 are designed to facilitate the circulation of high-temperature steam or cooling water within the annular coil 5.

[0025] For example, such as Figure 3 As shown, the present invention also includes a thermometer 303 connected to the top of the connecting pipe 301 via a threaded groove, and the end of the connecting pipe 301 away from the tee pipe 302 is fixed to one end of the liquid inlet pipe 6 via a flange.

[0026] When in use, the thermometer 303 can detect the temperature of the medium flowing inside the connecting pipe 301.

[0027] For example, such as Figure 1 As shown, this utility model also includes a temperature sensor 8 fixed to the signal input terminal of the temperature controller 2 by bolts, and the temperature sensor 8 is specifically two sets.

[0028] In use, the two temperature sensors 8 can detect the temperature of the stainless steel ring 1 and the internal temperature of the reaction equipment, respectively.

[0029] For example, such as Figure 2 As shown, this utility model also includes a heat-conducting plate 4 made of graphene material.

[0030] When in use, the heat-conducting plate 4 made of graphene material has good thermal conductivity and can quickly achieve heat exchange.

[0031] When using this utility model, personnel use bolts to fix the stainless steel ring 1 inside the reaction equipment. The size of the stainless steel ring 1 can be designed according to the size of the reaction equipment. The temperature controller 2 is fixed outside the reaction equipment using a mounting base. The two temperature sensors 8 are fixed inside the stainless steel ring 1 and the reaction equipment respectively. The device is connected to an external power source using a power cord.

[0032] One temperature sensor 8 is used to detect the temperature inside the stainless steel ring 1, and another temperature sensor 8 is used to detect the temperature inside the reaction equipment to ensure the accuracy of temperature control. The high-temperature steam outlet is connected to the first solenoid valve 304 through a pipe, and the cooling water outlet is connected to the second solenoid valve 305 through a pipe.

[0033] After the first solenoid valve 304 is opened, high-temperature steam flows through the three-way pipe 302, connecting pipe 301 and liquid inlet pipe 6 into the annular coil 5 and is discharged from the liquid outlet pipe 7. The high-temperature steam circulates in the annular coil 5. The heat-conducting plate 4 absorbs the heat of the high-temperature steam in the annular coil 5 and conducts it to the stainless steel ring 1 to heat the water-based acrylic modified polyurethane in the reaction equipment.

[0034] The first solenoid valve 304 is closed and the second solenoid valve 305 is opened, allowing cooling water to flow through the three-way pipe 302, connecting pipe 301 and inlet pipe 6 into the annular coil 5 and out of the outlet pipe 7. The cooling water circulates in the annular coil 5, cooling the heat-conducting plate 4 that has absorbed the heat of the water-based acrylic modified polyurethane, thereby cooling the water-based acrylic modified polyurethane.
