Abstract

The invention relates to a shock absorption polyurethane material which comprises the components in parts by weight: 100-200 parts of polyether TMN3050, 50-100 parts of phenolic resin, 15-20 parts of phenol resin, 1-5 parts of cross-linking agent, 2-5 parts of coupling agent, 5-10 parts of stearic acid, 15-20 parts of calcium carbonate, 50-100 parts of aluminite powder and 0.5-2 parts of triethylene diamine. The shock absorption material used for a car elevator has the functions of preventing vibration and reducing buffer, and has the impact elasticity of 25-50%, the tensile strength of 15-20MPa and the elongation of 100-150%.

Description

technical field [0001] The invention belongs to the technical field of safety materials, in particular to a polyurethane material for shock absorption. Background technique [0002] The bottom of the elevator pier means that when all the control systems fail, the elevator car will miss the leveling position of the first floor and drive downward until it stops on the buffer of the bottom pit. Such a situation rarely happens, but once it happens, the consequences will be very serious, and the huge inertia is likely to cause the whole body of the elevator rider to fracture and endanger life. In fact, if the elevator suddenly falls rapidly during its descent, the safety protection device of the elevator will stop the elevator. Therefore, the safety performance of the elevator car is particularly important. When the above situation occurs, if the bottom of the car and the walls around the car are provided with shock-absorbing materials, it can effectively prevent casualties of t...
