Abstract
The utility model discloses a solvent evaporating device for a solvent-based pressure-sensitive adhesive (PSA). The solvent evaporating device mainly consists of an evaporating kettle, a condensing device, a solvent recovery tank, heating devices and a stirrer, wherein the cavity of the evaporating kettle is sealed, the top of the evaporating kettle is communicated with the condensing device by a pipeline, and a cooling liquid outlet of the condensing device is communicated with the solvent recovery tank by the pipeline; and the heating devices are arranged at the bottom and the side part of the evaporating kettle, and the evaporating kettle is internally provided with the stirrer. The solvent evaporating device totally removes and recovers solvents (methylbenzene and acetic ether) in an airtight environment after the PSA is polymerized, and the solvent evaporating device has a recovery rate of more than 99.9 percent, thereby reducing the overall cost of the adhesive and avoiding the environmental pollution.
Description
Technical field
The utility model relates to a kind of solvent evaporation equipment of solvent-borne type pressure sensitive adhesive, belongs to the adhesive material preparing technical field.
Background technology
Pressure sensitive adhesive (pressure sensitive adhesive) is the abbreviation of pressure-sensitive adhesive, is a class has sensitiveness to pressure adhesive.Pressure sensitive adhesive can be divided into rubber-type and resin type two classes according to the matrix resin composition, and rubber-type can be divided into natural rubber and synthetic rubber class again, and resin type mainly comprises polyacrylate, silicone based and polyurethanes again.According to the difference of decentralized medium, be divided into water-based and solvent-borne type pressure sensitive adhesive.Water-borne pressure sensitive adhesive is to react with the medium of water as reaction, promptly gets the pressure sensitive adhesive goods after the coating oven dry.Because water-borne pressure sensitive adhesive adopts water as solvent, so it is cheap, throughput rate is very fast, but its adhesive performance is not high.Solvent-borne type pressure sensitive adhesive toluene, organic solvents such as ethyl acetate react as the medium of reaction, and in solvent-borne type pressure sensitive adhesive finished product, organic solvent accounts for 60～75% of gross weight, and adhesive accounts for 25～40% of gross weight.
The technology maturation of solvent-borne type pressure sensitive adhesive has good pressure-sensitive and caking property, again because advantages such as resistances to ag(e)ing, light resistance, resistance to water, oil resistivity, so almost not through the time change the problem that causes that pressure-sensitive descends, and peelable performance is good.At present, the solvent-borne type pressure sensitive adhesive is owing to environmental issue causes progressively dwindling of the scope of application, its reason is: because the solvent-borne type pressure sensitive adhesive is in the process of coating, the a large amount of organic solvent evaporations that need wherein to contain fall, and therefore the problem that causes mainly contains: one, the long processing time of pressure sensitive adhesive goods; Two, Zheng Fa solvent causes actual bodily harm to the operator; Three, Zheng Fa solvent itself does not have sufficient utilization can cause waste yet; In heating process, substrates coated is damaged.
Summary of the invention
The utility model provides a kind of solvent evaporation equipment of solvent-borne type pressure sensitive adhesive, and purpose is to solve the solvent-borne type pressure sensitive adhesive needs evaporating solvent in the process of coating problem.
For achieving the above object, the technical solution adopted in the utility model is: a kind of solvent evaporation equipment of solvent-borne type pressure sensitive adhesive, mainly form by evaporating kettle, condensing unit, solvent recovery jar, heater and agitator, the bore seal of described evaporating kettle, its top is communicated with described condensing unit by pipeline, and the cooling liquid outlet of described condensing unit is communicated with described solvent recovery jar by pipeline; The bottom of described evaporating kettle and sidepiece are all established described heater, and described agitator is established in its inside.
Related content in the technique scheme is explained as follows:
1, in the such scheme, described evaporating kettle is provided with thermometer and Pressure gauge.
2, in the such scheme, described evaporating kettle is provided with charging aperture, and charging aperture is provided with seal valve.
3, in the such scheme, described condensing unit adopts water cooling plant, can be on the pipeline between evaporating kettle and the solvent recovery jar coil pipe of outsourcing with water inlet and delivery port.
4, in the such scheme, described heater can be steam heater or electric heater unit.
5, in the such scheme, described agitator is made of axle and blade.
Because the technique scheme utilization, the utility model compared with prior art has following advantage:
1, the utility model all removes the solvent after the pressure sensitive adhesive polymerization (toluene, ethyl acetate) in closed environment and all reclaims, and its rate of recovery is up to more than 99.9%, thereby the whole cost of reduction adhesive is avoided environmental pollution.
2, the organic solvent that toluene, ethyl acetate equal solvent type pressure sensitive adhesive are commonly used has features such as poisonous, inflammable, in the roasting adhesive process when the solvent-borne type pressure sensitive adhesive directly is coated with, when heating makes the organic solvent volatilization, cause operative employee's actual bodily harm at first easily, next has explosion danger, and the utility model is owing to evaporated solvent and recovery before coating, therefore can effectively avoid the coating process potential safety hazard, and can improve coating production efficiency greatly by saving the roasting required time of glue.

Accompanying drawing 1 is the utility model schematic diagram.
In the above accompanying drawing: 1, evaporating kettle; 2, condensing unit; 3, solvent recovery jar; 4, heater; 5, agitator; 6, thermometer; 7, Pressure gauge.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described:
Embodiment one: a kind of solvent evaporation equipment of solvent-borne type pressure sensitive adhesive
Shown in accompanying drawing 1, a kind of solvent evaporation equipment of solvent-borne type pressure sensitive adhesive, mainly form by evaporating kettle 1, condensing unit 2, solvent recovery jar 3, heater 4 and agitator 5, the bore seal of described evaporating kettle 1, its top is communicated with described condensing unit 2 by pipeline, and the cooling liquid outlet of described condensing unit 2 is communicated with described solvent recovery jar 3 by pipeline; The bottom of described evaporating kettle 1 and sidepiece are all established described heater 4, and described agitator 5 is established in its inside.Described evaporating kettle 1 is provided with thermometer 6 and Pressure gauge 7.
The utility model at first adds the solvent-borne type pressure sensitive adhesive by charge door in evaporating kettle 1 when work, close the bore seal that charge door makes evaporating kettle 1 then.Open heater 4 then, heating makes the solvent in the solvent-borne type pressure sensitive adhesive of evaporating kettle reach boiling point, and solvent becomes gaseous state by liquid state, when the solvent of gaseous state is flowed through described condensing unit 2 by pipeline, becomes liquid state again, flow to described solvent recovery jar 3 then and collects.
