[0002] Styrene acrylic resin is a copolymer of styrene-acrylic acid and its esters. This polymer can dissolve or swell in water, or form a highly uniformly dispersed dispersion. It is a very important type of water-based polymer and usually has good wear resistance, chemical resistance, weather resistance and mechanical properties.

[0003] At present, the preparation method of styrene-acrylic resin is to mix the raw materials to make a suspension, then solidify the suspension to obtain solid styrene-acrylic resin, and then crush the styrene-acrylic resin to obtain granular styrene-acrylic resin for use in other fields.

[0068] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0069] Embodiment 1:

[0070] like Figure 1 As shown, one embodiment of the present invention provides a styrene acrylic resin production line, the production line comprising:

[0071] A frame 100, wherein a lower working support 110 disposed obliquely is disposed on the frame 100, and an upper material position and a lower material position are disposed on the lower working support 110;

[0072] A plurality of mixing tanks 200, wherein the mixing tanks 200 roll on the lower working support 110 and the upper working support 120, wherein a first mixing plate 230 is provided on the inner wall of the mixing tank 200 for stirring materials, and a feeding port is provided on the side wall of the mixing tank 200, wherein a pipe orifice sealing valve 210 is provided in the feeding port for sealing the mixing tank 200, wherein when the mixing tank 200 rolls to the feeding position, the feeding port of the mixing tank 200 is located at the upper part, and when the mixing tank 200 rolls to the feeding position, the feeding port of the mixing tank 200 is located at the lower part;

[0073] A feeding mechanism 300 located at the feeding position, after the feeding mechanism 300 is connected to the feeding port of the mixing tank 200, the pipe port sealing valve 210 is opened to add materials, and the feeding mechanism 300 is connected to a plurality of feeding mechanisms;

[0074] A material unloading mechanism 600 is located at the unloading position. After the material unloading mechanism 600 is connected to the material loading port of the mixing tank 200, the pipe port sealing valve 210 is opened to release the material in the mixing tank 200;

[0075] A curing mechanism 500 located at a material discharge position, wherein the curing mechanism 500 is connected to the material discharge mechanism 600 to cure the material discharged from the material discharge mechanism 600;

[0076] The tank transfer unit is used to transfer the mixing tank 200 from the lower material position to the upper material position;

[0077] Specifically, in this embodiment, when producing styrene-acrylic resin, the empty mixing tank 200 is placed at the loading position in sequence. At this time, the loading port of the mixing tank 200 is located on the upper side, the loading mechanism 300 is connected to the loading port of the mixing tank 200 and the nozzle sealing valve 210 is opened, and the feeding mechanism adds materials (such as styrene monomer, acrylic monomer, chain transfer agent and initiator) into the mixing tank 200 in proportion through the loading mechanism 300. After the material addition is completed, the loading mechanism 300 is separated from the nozzle sealing valve 210, and the nozzle sealing valve 210 closes the loading port of the mixing tank 200. Since the lower working support 110 is inclined, the mixing tank 200 is placed on the lower working support 110 under the action of gravity. Rolling, when the mixing tank 200 rolls, the first mixing plate 230 in the mixing tank 200 stirs the material in the mixing tank 200, so that the material in the mixing tank 200 is evenly mixed. When the mixing tank 200 rolls to the unloading position, the material in the mixing tank 200 is mixed. At this time, the loading port on the mixing tank 200 is located at the bottom, and the unloading mechanism 600 is connected to the loading port. The unloading mechanism 600 opens the pipe mouth sealing valve 210, so that the material in the mixing tank 200 flows from the unloading mechanism 600 into the curing mechanism 500 to complete the curing in the curing mechanism 500. The empty mixing tank 200 then flows from the unloading position to the loading position, thereby completing the continuous operation of the production line;

[0078] The styrene-acrylic resin production line disclosed in the embodiment of the present invention is provided with an inclined lower working support 110 and a mixing tank 200 rolling on the lower working support 110, so that the stirring and transfer of materials can be combined. After the loading is completed, the material can be transported while being stirred, so that the intermittent work of feeding and stirring is turned into continuous work, eliminating the waiting time for feeding and stirring, thereby improving production efficiency.

Since there is material in the mixing tank 200, the mixing tank 200 will slow down when rolling the horizontal section, so that the mixing tank 200 can slowly roll to the material discharge position;

[0080] It should be noted that, through limited experiments, the length of the lower working support 110 can be reasonably selected so that when the mixing tank 200 rolls to the lower material position, the materials in the mixing tank 200 can be mixed. At the same time, through limited experiments, the lengths of the inclined section and the horizontal section on the lower working support 110 can be reasonably selected so that when the mixing tank 200 containing the material rolls to the lower material position, the mixing tank 200 is just located at the lower material position.

The valve spring 215 tightens the valve plug 214 on the valve ring 213 through the valve stem 212. When the valve stem 212 is pressed, the valve plug 214 is separated from the valve ring 213, thereby opening the feeding port;
