Abstract
The invention discloses a kind of integral type polyurethane synchronous belt, it is characterized in that, it includes the timing belt main body that integrally formed hard polyaminoester teeth layer and flexibel polyurethane basic unit are constituted, and the shore hardness of hard polyaminoester is 91 93A, and the shore hardness of flexibel polyurethane is 55 60A.Preparation technology of the present invention is simple, production safety, environmental protection.
Description
Technical field
The present invention relates to timing belt technical field, a kind of integral type polyurethane synchronous belt and its preparation side are specifically related to
Method.
Background technology
Existing polyurethane synchronous belt is typically constituted by 2 layers, toothed portion have the higher polyurethane of hardness into, contact surface by
Butadiene-styrene rubber is constituted.Because 2 layer material physical properties are different, it is therefore desirable to carry out a series of complex process technique：First
Layer of polyurethane feather plucking-cleaning up-is brushed after corresponding activator progress is handled-activated and brushes corresponding binding agent.Butylbenzene
Rubber feather plucking-cleaning up-brushes corresponding activating treatment agent and brushed after activating-activating corresponding binding agent-poly- ammonia
Ester layer carries out pressurized adhesion with butadiene-styrene rubber layer with vulcanizing press.Its preparation technology is complicated, low production efficiency, and to use
The materials such as poisonous toluene are cleaned and activated, and there is certain potential safety hazard.
The content of the invention
The purpose of the present invention is exactly the preparation side in order to which the one kind for solving the deficiency of prior art and providing is not only simple in structure
Just, the high integral type polyurethane synchronous belt of production efficiency.
It is a further object of the present invention to provide a kind of preparation method of integral type polyurethane synchronous belt.
The present invention is to realize above-mentioned purpose using following technical solution：A kind of integral type polyurethane synchronous belt, its
It is characterised by, it includes the timing belt main body that integrally formed hard polyaminoester teeth layer and flexibel polyurethane basic unit are constituted, firmly
The hardness (shore) of matter polyurethane is 91-93A, and the hardness (shore) of flexibel polyurethane is 55-60A.
As a further illustration of the above scheme, being provided with metallic framework in the timing belt main body.
The metallic framework is arranged in hard polyaminoester teeth layer.
The metallic framework is made up of at least one layer of wire netting, and the wire netting is formed by metal wire knitted.
The metallic framework includes some one metal wires in the same plane, and some one metal wires are parallel to each other, and
It is spaced each other.
The wire is 0.5-5mm steel wire.
A kind of preparation method of integral type polyurethane synchronous belt, it is characterised in that it is poured into tooth form metal die
One layer of high hardness polyurethane for forming hard polyaminoester teeth layer, after the strata urethane is in gel state, then is poured into
Another is used for the flexibel polyurethane for forming flexibel polyurethane basic unit, and pressurize sulphur after flexibel polyurethane is in gel state
Change, be stripped after 20-40 minutes, post-cure in 10-16 hours is then carried out with 100-130 DEG C of baking oven；Wherein, hard polyaminoester
Hardness (shore) is 91-93A, and the hardness (shore) of flexibel polyurethane is 55-60A.
Further, before high hardness polyurethane is poured into toward tooth form metal die, in addition it is also necessary to first in tooth form metal die
Metallic framework is set.
The beneficial effect that the present invention can be reached using above-mentioned technical solution is：
1st, the present invention waits this strata urethane to be in using the higher polyurethane of the hardness of falling last layer in tooth form metal die
Another hardness flexibel polyurethane suitable with butadiene-styrene rubber is gone up after gel state again, be instead of as stated in the Background Art
Complicated technology, production and processing safety.
2nd, the present invention can further strengthen the power of timing belt by the increase metallic framework in hard polyaminoester teeth layer
Learn performance, more durable.
Brief description of the drawings
Fig. 1 is integral type polyurethane synchronous belt structural representation of the invention.
Description of reference numerals：1st, hard polyaminoester teeth layer 2, flexibel polyurethane basic unit 3, metallic framework.
Embodiment
The technical program is explained in detail below in conjunction with specific embodiment.
Embodiment 1
As shown in figure 1, the present invention is a kind of integral type polyurethane synchronous belt, it includes integrally formed hard polyaminoester tooth
The timing belt main body that dental layers 1 and flexibel polyurethane basic unit 2 are constituted, the hardness (shore) of hard polyaminoester is 91-93A, soft poly-
The hardness (shore) of urethane is 55-60A.Metallic framework 3 is provided with timing belt main body.In the present embodiment, metallic framework 3 is set
In hard polyaminoester teeth layer 1.Metallic framework includes some one metal wires in the same plane, some one metal wire phases
Mutually parallel and spaced each other, wire is 1mm steel wire.
The following is the preparation method of integral type polyurethane synchronous belt, it is to insert metallic framework in tooth form metal die,
One layer of high hardness polyurethane for being used to form hard polyaminoester teeth layer is poured into, after the strata urethane is in gel state, then
Another flexibel polyurethane for being used to form flexibel polyurethane basic unit is poured into, is pressurizeed after flexibel polyurethane is in gel state
Vulcanization, is stripped after 30 minutes, then carries out post-cure in 12 hours with 110 DEG C of baking ovens.
