Description
Technical field
The utility model relates to a kind of low molecular system that takes off of controlling organic silicon high-temperature glue rubber volatile matter.
Background technology
Silicon raw rubber is the basic polysiloxane of uncured (crosslinked), be called for short rubber, it is the linear polydiorganosiloxane of a class high molecular weight, be mixed into sizing material with various Synergist S-421 95s, again through heating, the sulfuration of pressurization compacted under, obtain the silastic product of different purposes, in industry such as aviation, aerospace, electric, electronics, electrical equipment, chemical industry, instrument, automobile, machinery and health care, daily life every field, obtained to use widely.
Rubber productive target index mainly contains 3 of molecular weight, volatile matter, contents of ethylene in the GB, and every index of rubber all will influence the performance of mixing processing subsequent production and cross-linked rubber.The processibility that how much will influence rubber unvulcanizate production of the volatile matter of rubber and the shrinking percentage of silica gel goods.
The rubber volatile matter enters to be at rubber and is removed in a large number when taking off under the vacuum state hanged down molecular device, also can contain a spot of volatile matter in the rubber finished product that obtains.Control its vacuum state owing to take off low molecular device by vacuum pump, concrete vacuum tightness can't accurately be regulated, the manufacturer of therefore general rubber can accurately not control the rubber volatile matter, the span of control of volatile matter is less, be generally 1%～3%, can not produce the rubber of the special volatile matter of the too high or too low index that the client needs, can not provide favourable condition, also be difficult to resolve the problem that certainly causes silica gel goods correlated performance because of volatile matter for follow-up rubber unvulcanizate production.
The utility model content
The utility model provides a kind of low molecular system that takes off of controlling organic silicon high-temperature glue rubber volatile matter, and is used for the production of organic silicon high-temperature glue rubber, can accurately control the rubber volatile matter, and the span of control of volatile matter is 1%～10%.
Describedly take off low molecular system, comprise vacuum pump, take off low molecular device and emptying device, vacuum pump, emptying device all hang down molecular device and are connected with taking off, and described emptying device is interconnected valve and under meter.Described to take off low molecular device be the public device of this area, comprises and take off low molecule device, condenser and take off low molecule groove, take off low molecule device with condenser, hang down the molecule groove and be linked in sequence, vacuum pump all is connected with low molecule groove with emptying device.As improvement project, described emptying device also comprises and valve and the placed in-line air filtering core device of under meter.As preferred version, the vacuum pump ultimate pressure is 1.3kPa, and for 20 ℃, the air of 101.3KPa, the useful range of spinner-type flowmeter is 1～10m3/h.Produced the rubber of low volatile as need, and took off low system and can use two vacuum pumps simultaneously, reached the purpose that reduces the rubber volatile matter with this to improve vacuum suction speed.
As improvement of the present utility model, described emptying device also comprises and valve and the placed in-line air filtering core device of under meter.Air filtering core device can filter and enter the air that takes off low molecular device, takes off low molecular device in order to avoid impurity such as dust enter, otherwise dust that enters and impurity discharged by the discharge machine in company with rubber, causes the rubber outward appearance defective.
Described valve can be selected suitable valve according to actual needs, is preferably needle type valve, good seal performance, valve sensitivity and reliability height, easily adjusting.
The utility model enters the air flow quantity of taking off low molecular device by setting up emptying device taking off on the low molecular device by regulating through emptying device, regulates the vacuum tightness of taking off low molecular device, the content of control organic silicon high-temperature glue rubber volatile matter.Because emptying device is interconnected valve and under meter, can accurately finely tune the vacuum tightness of taking off low molecular device easily, not only accurately control the rubber volatile matter, and the span of control of volatile matter can be extended to 1%～10% by common 1%～3%.
Description of drawings
Fig. 1 is the used structural representation that takes off low molecular system of the utility model.
Embodiment
Take off low molecular system as shown in Figure 1, comprise vacuum pump 4, take off low molecular device and emptying device, describedly take off low molecular device and comprise taking off low molecule device 1, condenser 2 and taking off low molecule groove 3 of being linked in sequence, described emptying device is valve 5, under meter 6 and the air filtering core device 7 that is linked in sequence, valve 5 is a needle type valve, the valve 5 of vacuum pump 4, emptying device all with take off low molecule groove 3 and be connected.The vacuum pump ultimate pressure is 1.3kPa, is standard with 20 ℃, the air of 101.3kPa, and the useful range of spinner-type flowmeter is 1～10m
3/ h.
With above-mentioned when taking off low molecular system and being used for the production of organic silicon high-temperature glue rubber, open vacuum pump earlier, make and take off low molecular device and be vacuum state, the high-temp glue rubber enters temperature with the logistics speed of 230～240kg/h and is controlled at the low molecule device 1 of 180～200 ℃ take off, volatile matter wherein enters through condenser 2 and takes off low molecule groove 3, is discharged by the bottom of taking off low molecule groove 3.By regulated valve 5, control makes the float of spinner-type flowmeter rest on the 5.5m3/h place by the air flow quantity of air filtering core device, and the rubber fugitive constituent that obtains like this is 7.56%.
