Abstract
The invention relates to a road manhole cover accessory and a formula thereof, in particular to a manhole cover component with a cushion and a formula of the cushion. The manhole cover component with the cushion comprises a manhole cover body. The manhole cover component is characterized by further comprising the annular cushion which is detachably mounted on the inner surface of the manhole cover body. The annular cushion is arranged on the reverse side of the manhole cover body, so that a damping effect is achieved at the matched joint of the manhole cover and the ground, noise of the manhole cover due to passing vehicles is avoided, vibration of the manhole cover is reduced, and the manhole cover is not easy to damage. The formula of the cushion comprises polyester, isocyanic acid and diphenylmethane diisocyanate. Toluene diisocyanate is replaced by the diphenylmethane diisocyanate, so that toxicity is greatly reduced, and environment-friendly performance is improved. Rail cushions produced according to the formula have high hydrolysis resistance.
Description
Technical field
The present invention relates to a kind of accessory and formula thereof of road well lid, especially a kind of manhole cover assembly with cushion pad and the formula of cushion pad thereof.
Background technology
Under the present situation of high speed development, in order to meet the demand of crowd's trip, the newly-built of road is absolutely necessary, and what bring is underground water pipeline thereupon, in inferior process, need on road, build the join domain of pipeline, build circular manhole on road, there is potential safety hazard in the circular manhole on this road; In order to solve this hidden danger, generally adopt manhole cover to address this problem, make manhole cover and people on urban road live closely bound up, and coordinate with circular manhole while closely not having loosening situation to exist when manhole cover, passing vehicle can make manhole cover vibrations produce noise, affects people's quality of life, and this situation frequency is when frequent, manhole cover very easily damages, and has potential safety hazard.
Summary of the invention
The present invention solves the problems of the technologies described above taked following technical scheme:
Provide a kind of manhole cover assembly with cushion pad on the one hand, comprised manhole cover body, it is characterized in that: also include profile cushion pad in the form of a ring, this ring-type cushion pad is detachably installed on the inner surface of manhole cover body.
Be preferably, described cushion pad comprises buffer part and the transition part being connected with buffer part, and the thickness of buffer part is greater than the thickness of transition part.
Be preferably, the ratio of the thickness of described buffer part and the thickness of transition part is 1.5-2.
Be preferably the twice of the girth that the girth of described transition part is buffer part.
By adopting technique scheme, at the back side of manhole cover body, be provided with loop buffer pad, effectively the cooperation place on manhole cover and ground is played to the effect of buffering, the situation of having avoided vehicular traffic to produce noise to manhole cover exists, the situation that has reduced manhole cover vibrations occurs, and makes manhole cover not fragile.
A formula for cushion pad, comprises polyester, carbimide and diphenylmethane diisocyanate fat on the other hand.
The present invention is preferably, and the ratio of above-mentioned polyester and carbimide is between 100:9 and 100:7.
The present invention is preferably, and the ratio of above-mentioned polyester and diphenylmethane diisocyanate fat is between 100:30 and 100:10.
The present invention is preferably, and described carbimide is carbimide mm103C.
This carbimide mm103C is a kind of Carbodiimide-Modified 44 methyl diphenylene diisocyanates of liquid state, and its semiproduct of producing have a large amount of micropores, and the elastic body of making has improved whole buffering effect greatly.
By adopting technique scheme, utilize diphenylmethane diisocyanate fat to replace dimethylbenzene diisocyanate resin component, greatly reduced toxicity, improved environmental-protecting performance, the rail cushion pad obtaining by above-mentioned formula, there is higher anti-hydrolytic performance, guaranteed this rail cushion pad hot strength, break extension rate, hardness, tearing strength and tear the physical properties such as elongation rate.
Accompanying drawing explanation
Fig. 1 is with the manhole cover modular construction schematic diagram of cushion pad in the specific embodiment of the invention.
Fig. 2 is the perspective view of cushion pad in the specific embodiment of the invention.
Fig. 3 is the structure schematic side view of cushion pad in the specific embodiment of the invention.
The specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described.
As shown in Fig. 1-Fig. 3, one aspect of the present invention discloses a kind of manhole cover assembly with cushion pad, comprise manhole cover body 2, it is characterized in that: also include profile cushion pad 1 in the form of a ring, this ring-type cushion pad 1 is detachably installed on the inner surface of manhole cover body 2, described cushion pad 1 comprises buffer part 11 and the transition part 12 being connected with buffer part 11, the thickness of buffer part 11 is greater than the thickness of transition part 12, the ratio of the thickness of described buffer part 11 and the thickness of transition part 12 is 1.5-2, and the girth of described transition part 12 is the twice of the girth of buffer part 11.
By adopting technique scheme, at the back side of manhole cover body, be provided with loop buffer pad, effectively the cooperation place on manhole cover and ground is played to the effect of buffering, the situation of having avoided vehicular traffic to produce noise to manhole cover exists, the situation that has reduced manhole cover vibrations occurs, make manhole cover not fragile, and the thickness of buffer part is greater than the thickness setting of transition part, buffer part is when pressurized, transition part is in the situation of pressurized not, reported the application life of transition part, and buffer part thickness is thicker, shock-absorbing capacity is better, make the topology layout of integrated buffer pad more reasonable.
The present invention discloses a kind of formula of cushion pad on the other hand, comprises polyester, carbimide and diphenylmethane diisocyanate fat.
The present invention is preferably, and the ratio of above-mentioned polyester and carbimide is between 100:9 and 100:7.
The present invention is preferably, and the ratio of above-mentioned polyester and diphenylmethane diisocyanate fat is between 100:30 and 100:10.
The present invention is preferably, and described carbimide is carbimide mm103C.
This carbimide mm103C is a kind of Carbodiimide-Modified 44 methyl diphenylene diisocyanates of liquid state, and its semiproduct of producing have a large amount of micropores, and the elastic body of making has improved whole buffering effect greatly.
