Abstract
A process for preparing the rubber roller used for textile from polyurethane instead of rubber includes such steps as pre-polymerizing reaction between polyol and isocyanate to obtain NCO-base prepolymer of polyurethane, reacting on the chain-extending cross-linking agent to obtain CPU, installing workpiece on supporting tray, automatic locating, pouring and advancing, closing pouring chamber, vacuumizing, automatic advancing, quantitatively filling, delaying, filling air, opening pouring chamber, taking rubber roller out and curing.
Description
Technical field:
The present invention relates to a kind of method of making textile rubber roll of polyurethane.
Background technology:
What the employed textile rubber roll of textile industry adopted mostly at present makes of acrylonitrile-butadiene rubber, and service life is short, must be coated with last layer coating before using.Otherwise be prone to wrapping phenomena.The processing technology complexity also must be carried out grinding with grinding machine, and the manufacturer of rubber roll and use producer have all increased production cost like this.
Summary of the invention:
The object of the present invention is to provide a kind of can solving the problems of the technologies described above, make the method for fabric rubber roll of polyurethane.The technical scheme that is adopted is: earlier polyalcohol and isocyanates are given poly-reaction, the polyurethane of producing the NCO base gives polymers, again with chain extension-crosslinking agent prepared in reaction CPU, then workpiece is loaded on the pallet automatically and delays time 5-10 second → emptying after location and cast auto-feed → close perfusion compartment → vacuumize → auto-feed → quantitatively encapsulating → this batch workpiece all water and open perfusion compartment, take out workpiece, carry out post curing again and handle.The textile rubber roll of making of polyurethane is lower than the textile rubber roll abrasion of making of acrylonitrile-butadiene rubber, and rebound performance is good, need not grinding.Need not coat layer before using, wrapping phenomena can not occur, need not carry out the grinding repair process in the use.Can both reduce production costs for the producer and user, enhance productivity.
The specific embodiment
Polyurethane has four kinds of materials synthetic: 1, polyalcohol; 2, isocyanates; 3, chain extender; 4, catalyst.Polyurethane can have been bought at home, just produces polyurethane as the Wan Hua company in Yantai, Shandong.
The use of polyurethane is very extensive, for example aspect national defense industry, and the air packing of various artilleries, shellproof solid tyre, panzer shoe etc.Aspect light industry, as heat-insulation layer, top-grade furniture and the sole etc. of refrigerator.Also can see equipment and the product made from polyurethane at traffic, oil field, colliery, building, physical culture, medical field.
Textile rubber roll with polyurethane is made under the situation that does not add coating, the phenomenon that yarn twines rubber roll can not occur.This is the new discovery to the polyurethane material performance, in addition also has following advantage with the textile rubber roll that polyurethane is made than the textile rubber roll made from acrylonitrile-butadiene rubber:
1, abrasion are low: butyronitrile rubber roller 0.07cm
3/ 1.61km
Polyurethane rubber roller 0.007cm
3/ 1.61km
The two is compared, the wearing valve of polyurethane rubber roller than butyronitrile rubber roller low an order of magnitude.
2, rebound performance is good: butyronitrile rubber roller 15%-20%
Polyurethane rubber roller 40%-50%
The two is compared, and the rebound performance of polyurethane rubber roller is higher than nearly 2 times of butyronitrile rubber roller.
Must carry out the grinding of grinding machine when 3, butyronitrile rubber roller is produced.And polyurethane rubber roller does not need.
The low explanation polyurethane rubber roller time in service life of abrasion is long, and general butyronitrile rubber roller can use about 2 months, and mill is once used half a year at most.And polyurethane rubber roller is got on the bus to use and needn't be repaired and can reach more than 10 months.
Rebound performance is good, and it is good to illustrate with the spun yarn quality of polyurethane rubber roller, the ring phenomenon can not occur, reduces bar and does the CV% value.
Polyurethane rubber roller need not grinding when producing, and needn't grind preceding reparation in the use, manufacturer is described and uses producer all can reduce cost, and enhances productivity.
In specific implementation process, earlier polyalcohol and isocyanates are given poly-reaction, the polyurethane of producing the NCO base gives polymers, again with chain extension-crosslinking agent prepared in reaction CPU.
Make the method for polyurethane textile rubber roll:
1, technological process:
(1) CPU synthesis procedure:
A material: give aggressiveness (HTPB) and (vacuumize≤200Pa under stirring at a slow speed
→ filter in (80 order) → metering (measuring pump)
The B material: chain extender (MOCA) (110-120 ℃ of the fusing of heating under stirring at a slow speed) mixes → pour into a mould → filter (120 order) → metering (measuring pump) in pouring head
Each material is back to batch can separately when not pouring into a mould, to guarantee proportioning correct (material pipe, filter, measuring pump and pouring head are all worked) in the thermal conductance deep fat surrounds.Accurate voltage regulating device on the pouring head can be eliminated the leading or hysteresis when mixing.Each fluence of watering is watered fluence (being the duration of pouring) by the automatic control of computer program controller, and precision can reach 0.1g.
2, perfusion operation:
Workpiece (tool and mould) be loaded on pallet or the universal workbench automatically encapsulating → a collection of the workpiece of location and cast auto-feed → close perfusion compartment → be evacuated down to≤100Pa → auto-feed → quantitatively all pouring finish delay time 5-10 after second → emptying and open perfusion compartment of back, take out workpiece, carry out post curing again and handle (regularly constant temperature heating in baking oven).
2, technological parameter:
Total discharge-amount: but 3-10g/s 1-10 duration of pouring second each encapsulating amount: 3-100g
Design mixture ratio: A: B=100: 0-50 operating temperature: 60-140 ℃ of vacuum 133-266Pa (1-2Torr)
Claims (1)
- Make the method for textile rubber roll of polyurethane, it is characterized in that: earlier polyalcohol and isocyanates are given poly-reaction, the polyurethane of producing the NCO base gives polymers, again with chain extension-crosslinking agent prepared in reaction CPU, then workpiece is loaded on the pallet automatically and delays time 5-10 second → emptying after location and cast auto-feed → close perfusion compartment → vacuumize → auto-feed → quantitatively encapsulating → this batch workpiece all water and open perfusion compartment, take out workpiece, carry out post curing again and handle.
