Description

Technical Field

[0001] This utility model relates to the field of unsaturated polyester resin production technology, specifically to an unsaturated polyester resin dilution device. Background Technology

[0002] Unsaturated polyester resin is a very important and widely used thermosetting polymer material. It is a linear polymer synthesized by polycondensation reaction of unsaturated diacids and saturated diols. During the synthesis process, some saturated diacids are sometimes added to adjust the properties of the resin. Due to its good mechanical properties, electrical insulation, chemical corrosion resistance, ease of processing and molding, and relatively low cost, unsaturated polyester resin is widely used in various production and manufacturing scenarios.

[0003] Before unsaturated polyester resin leaves the factory or during use, a certain proportion of crosslinking monomers, such as styrene, are added to it to reduce viscosity, improve processability, and achieve dilution. When the unsaturated polyester resin and crosslinking monomers are diluted in the dilution device, the mixing process will cause frictional heat, which will lead to a local temperature increase. The polymerization rate of styrene will accelerate at high temperature, resulting in premature gelation and affecting the quality of the finished product. Utility Model Content

[0015] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0016] Please see Figure 1-4 As shown, an unsaturated polyester resin dilution device includes a dilution tank body 1 for diluting unsaturated polyester resin, a resin injection pipe 2 for conveying unsaturated polyester resin connected to one side of the surface of the dilution tank body 1, and a feed pipe 3 for conveying crosslinking monomers connected to the other side of the surface of the dilution tank body 1. A cooling box 4 is fixed to one side of the surface of the dilution tank body 1, and a water injection pipe 5 is provided on the surface of the cooling box 4. The device also includes: A heat exchange mechanism 6 is installed inside the body 1 of the dilution tank to absorb frictional heat during the mixing process. A connecting plate 9 is fixed to the surface of the grease injection pipe 2. A feeding mechanism 10 for conveying unsaturated polyester resin is provided on the surface of the connecting plate 9. The feeding mechanism 10 includes a motor 101 fixed to the surface of the connecting plate 9. The output shaft of the motor 101 is driven by a gear set to provide a rotating rod 102. An auger 103 is fixed to the surface of the rotating rod 102. Under the action of the motor 101, the rotating rod 102 drives the auger 103 to rotate, thereby pushing the viscous unsaturated polyester resin and accelerating the injection speed of the unsaturated polyester resin into the body 1 of the dilution tank.

[0017] The heat exchange mechanism 6 includes a water supply pump 61 fixed to the surface of the cooling tank 4 and a heat exchange pipe 62 connected to one side of the surface of the cooling tank 4. The heat exchange pipe 62 is wound in a ring around the inner cavity of the dilution tank body 1. The other end of the heat exchange pipe 62 is connected to a supply pipe 63. One end of the heat exchange pipe 62 is connected to a heating component 66. The supply pipe 63 passes through the inner cavity of the rotating rod 102 through a rotating connector. The other end of the supply pipe 63 is connected to a first return water pipe 64 through a rotating connector. The other end of the first return water pipe 64 is connected to a second return water pipe 64. Water pipe 65 and second return water pipe 65 are connected to one side of the working end of water supply pump 61. When unsaturated polyester resin and crosslinking monomer are stirred and diluted in the inner cavity of dilution tank body 1, the heat generated by friction can be transferred to heat exchange pipe 62. Then, under the action of water supply pump 61, the hot water in heat exchange pipe 62 passes through supply pipe 63. Under the action of supply pipe 63, the heat can be transferred to rotating rod 102 and auger 103. And under the action of first return water pipe 64 and second return water pipe 65, the hot water is input into cooling tank 4 to absorb heat and avoid local overheating. Heating component 66 includes a first heating pipe 661 connected to one end of heat exchange pipe 62. One end of the first heating pipe 661 is connected to a ring-shaped coiled pipe 662 wrapped around the surface of grease injection pipe 2. The other end of the ring-shaped pipe 662 is connected to a third return water pipe 663. The third return water pipe 663 is connected to the second return water pipe 65. Hot water can also heat a part of the grease injection pipe 2 through the ring-shaped pipe 662 and through the first return water pipe 664 and second return water pipe 65. The third return water pipe 663 flows into the second return water pipe 65. A one-way valve 7 is installed on the surface of the third return water pipe 663. The one-way valve 7 is also installed on the surface of the first return water pipe 64. Under the action of the one-way valves 7 on both sides, the flow range of water in the third return water pipe 663 and the first return water pipe 64 is defined, which improves the practicality of the device. An insulation shell 8 is fixed on the surface of the grease injection pipe 2. The insulation shell 8 is sleeved on the surface of the surrounding pipe 662, which improves the heating capacity of the surrounding pipe 662 to the grease injection pipe 2, thus improving the practicality of the device.

[0018] Working principle: When diluting unsaturated polyester resin, the unsaturated polyester resin can be injected into the dilution tank body 1 through the resin injection pipe 2, and the crosslinking monomer injected through the dilution tank body 1 and the injection pipe 3 is stirred to achieve the dilution effect.

[0019] Since unsaturated polyester resin is relatively viscous, during transportation, the rotating rod 102 can drive the auger 103 to rotate under the action of the motor 101, thereby accelerating the injection of unsaturated polyester resin and improving the practicality of the device.

[0020] When the unsaturated polyester resin and crosslinking monomer are stirred in the inner cavity of the dilution tank body 1, a certain amount of heat will be generated due to friction. Then, under the action of the water supply pump 61, water will circulate in several pipes. Under the action of the heat exchange tube 62, the heat in the inner cavity of the dilution tank body 1 can be absorbed, thereby achieving the purpose of avoiding local high temperature in the inner cavity of the dilution tank body 1.

[0021] During water circulation, the rotating rod 102, the auger 103, and the unsaturated polyester resin at the corresponding positions can be heated by the supply pipe 63 and the surrounding pipe 662, thereby reducing the viscosity of the unsaturated polyester resin and making it easier for the feeding mechanism 10 to feed the unsaturated polyester resin.

[0022] After the hot water carrying heat enters the cooling tank 4, the heat in the water can be dissipated under the action of the cooling tank 4. The cooling tank 4 can be an industrial chiller, and its working principle is existing technology and will not be described in detail here.

[0023] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any indirect modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
