Abstract
The utility model discloses a kind of integral type polyurethane synchronous belt, it is characterized in that, it comprises the Timing Belt main body of integrated hard polyaminoester teeth layer and flexibel polyurethane basic unit formation, and the shore hardness of hard polyaminoester is 91-93A, and the shore hardness of flexibel polyurethane is 55-60A.The utility model preparation process is simple, production safety, environmental protection.
Description
Technical field
The utility model relates to Timing Belt technical field, specifically relates to a kind of integral type polyurethane synchronous belt.
Background technique
Existing polyurethane synchronous belt is generally formed by 2 layers, and the polyurethane that toothed portion has hardness higher is made, and surface of contact is made up of styrene butadiene rubber.Because 2 layer material physical properties are different, therefore need to carry out a series of complex process technique: first polyurethane layer hacking-cleaning up-brush corresponding activator carries out processing-activate the corresponding Bond of rear brushing.The corresponding Bond of brushing after the corresponding activating treatment agent of styrene butadiene rubber hacking-clean up-brush is carried out activating-activate-polyurethane layer and styrene butadiene rubber layer vulcanizing press are carried out pressurized adhesion.Its complicated process of preparation, manufacturing efficiency is low, and will use the materials such as poisonous toluene and clean and activate, and there is certain potential safety hazard.
Summary of the invention
The one that the purpose of this utility model is exactly deficiency in order to solve prior art and provides not only structure is simple, easy to prepare, the integral type polyurethane synchronous belt that manufacturing efficiency is high.
The utility model adopts following technical solution to realize above-mentioned purpose: a kind of integral type polyurethane synchronous belt, it is characterized in that, it comprises the Timing Belt main body of integrated hard polyaminoester teeth layer and flexibel polyurethane basic unit formation, the hardness (shore) of hard polyaminoester is 91-93A, and the hardness (shore) of flexibel polyurethane is 55-60A.
Further illustrating as such scheme, is provided with metal frame in described Timing Belt main body.
Described metal frame is arranged in hard polyaminoester teeth layer.
Described metal frame is made up of at least one deck wire netting, and this wire netting is formed by metal wire knitted.
Described metal frame comprises some one metal wires in the same plane, and some one metal wires are parallel to each other, and leave interval each other.
Described wire is the steel wire of 0.5-5mm.
The beneficial effect that the utility model adopts above-mentioned technical solution to reach is:
1, the utility model adopts the polyurethane that the hardness of falling last layer is higher in profile of tooth metal mold, another hardness flexibel polyurethane suitable with styrene butadiene rubber is gone up again after being in gel state Deng this layer of polyurethane, instead of complicated technology as stated in the Background Art, production and processing safety.
2, the utility model by increasing metal frame in hard polyaminoester teeth layer, further can strengthen the mechanical property of Timing Belt, durable more.
Accompanying drawing explanation
Fig. 1 is integral type polyurethane synchronous belt structural representation of the present utility model.
Description of reference numerals: 1, hard polyaminoester teeth layer 2, flexibel polyurethane basic unit 3, metal frame.
Embodiment
Below in conjunction with specific embodiment, the technical program is explained in detail.
Embodiment 1
As shown in Figure 1, the utility model is a kind of integral type polyurethane synchronous belt, it comprises the Timing Belt main body of integrated hard polyaminoester teeth layer 1 and flexibel polyurethane basic unit 2 formation, the hardness (shore) of hard polyaminoester is 91-93A, and the hardness (shore) of flexibel polyurethane is 55-60A.Metal frame 3 is provided with in Timing Belt main body.In the present embodiment, metal frame 3 is arranged in hard polyaminoester teeth layer 1.Metal frame comprises some one metal wires in the same plane, and some one metal wires are parallel to each other, and leave interval each other, and wire is the steel wire of 1mm.
Below the preparation method of integral type polyurethane synchronous belt, it inserts metal frame in profile of tooth metal mold, pour the high hardness polyurethane of one deck for the formation of hard polyaminoester teeth layer into, after this layer of polyurethane is in gel state, pour another flexibel polyurethane for the formation of flexibel polyurethane basic unit again into, be in press vulcanization after gel state until flexibel polyurethane, the demoulding after 30 minutes, then carry out post-cure in 12 hours with 110 DEG C of baking ovens.
Embodiment 2
In the present embodiment, metal frame is made up of at least one deck wire netting, and this wire netting is formed by metal wire knitted, and wire is the steel wire of 2mm.
Below the preparation method of integral type polyurethane synchronous belt, it inserts metal frame in profile of tooth metal mold, pour the high hardness polyurethane of one deck for the formation of hard polyaminoester teeth layer into, after this layer of polyurethane is in gel state, pour another flexibel polyurethane for the formation of flexibel polyurethane basic unit again into, be in press vulcanization after gel state until flexibel polyurethane, the demoulding after 35 minutes, then carry out post-cure in 11 hours with 120 DEG C of baking ovens.
The utility model compared with prior art, adopt the polyurethane that the hardness of falling last layer is higher in profile of tooth metal mold, Deng this layer of polyurethane be in gel state after go up another hardness flexibel polyurethane suitable with styrene butadiene rubber again, technique is simple, production and processing safety.
Above-described is only preferred implementation of the present utility model; it should be pointed out that for the person of ordinary skill of the art, under the prerequisite not departing from the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
