Abstract
The utility model relates to a flame-retardant vibration-insulation bracket which is mainly used as the bracket of bridges and houses. The bracket has a laminate structure which is obtained through separately overlapping steel plates (1) and inner-layer rubber (2). Furthermore a protection rubber layer (3) is coated outside the laminate structure. The inner-layer rubber mainly perform the functions of: bearing load, absorbing vibration energy, and providing binding strength with the steel plates. The protection rubber layer is coated outside the laminate structure which is composed of the steel plates and the inner rubber layers and forms a protection layer which protects the inner structure. The protection rubber layer mainly performs functions of retarding flame and delaying aging of internal rubber.
Description
Technical field
The utility model relates to a kind of fire-retardant vibration isolating suspension.Be mainly used in bridge and bearing is made in the house.Belong to Shock-proof for building and vibration isolation technique field.
Background technology
The rubber vibration isolating suspension rises and is used for the sixties in 20th century, and what use the rubber vibration isolating suspension the earliest is a primary school of Yugoslavia's science popularization Ji earthquake reconstruction in 1969.This building is one 3 layer concrete structure; Technical know-how at that time is limited, and seat structure is that simple use gum is used for reducing vibration unlike present rubber vibration isolating suspension; The centre has no strengthening measure, thereby the weight in house makes rubber side play drum.Along with people's was goed deep into the research of bearing afterwards, had carried out improving several times, made vibration isolating suspension can bear bigger weight.Is that some countries of master have carried out lot of performance and scientific research to the rubber vibration isolating suspension in the seventies with the U.S., Japan, France and Malaysia, and the application technology of rubber vibration isolating suspension is reached its maturity.China starts late to the research of rubber vibration isolating suspension, and just begin this technology is paid close attention to the eighties in 20th century, and the application of rubber vibration isolating suspension in builing industry is just ripe gradually after the nineties.Now, bridge and house are main with the natural gum bearing mainly at a large amount of lamination vibration isolating suspensions that use, and the natural gum vibration isolating suspension has bigger vertical rigidity, when bearing substantial load vertical deformation little, and horizontal rigidity is less, and the horizontal linearity performance is good.Though the natural gum vibration isolating suspension has lot of advantages; But blemish in an otherwise perfect thing is that the anti-flammability and the resistance to ag(e)ing of natural gum itself is poor, and natural gum belongs to hydrocarbon rubbers, and oxygen index (OI) is between 19-21; Pyrolysis temperature range is at 200-250 ℃; Its heat-resisting and poor fire, and when burning catabolite be main mainly with imflammable gas, the conventional method that solves natural gum vibration isolating suspension poor fire is in natural gum, to add a large amount of fire retardants; Improve anti-flammability, and add fire retardant in a large number and can bring a series of problem again:
The first, guarantee that fire retardant can fully mix, must increase mixing number of times, prolong mixing time, power consumption increases; The second, fire retardant is too much, and mixing time prolongs, and may cause the physical property of sizing material own to descend; The 3rd, the product after the excessive sulfuration of fire retardant may cause spray white, and fire retardant is separated out because of saturated in rubber, in use fire retardant also can be gradually from rubber inside to surface migration, the time has been grown anti-flammability decline.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned deficiency; Provide a kind of can be when satisfying the vibration isolating suspension mechanical property; Can also make it have excellent flame-retardant performance and excellent in resistance aging, and at the long-time fire-retardant vibration isolating suspension that uses the back properties of product can not descend.
The purpose of the utility model is achieved in that a kind of fire-retardant vibration isolating suspension, and said bearing is superposeed at interval by steel plate and internal layer rubber and constitutes laminated construction, and coats layer protective layer rubber in the outer rim of said laminated construction.
Internal layer rubber mainly plays bearing load, absorbed oscillation energy and the adhesion strength with steel plate is provided.Topping rubber is coated on outside the laminated construction of steel plate and internal layer rubber formation, forms the topping of layer of protecting internal construction.Topping rubber mainly plays a part fire-retardant and delays inner rubber to wear out.
Compare with existing vibration isolating suspension, the utility model bearing has following characteristics:
1, internal layer rubber can satisfy the mechanical property of lamination vibration isolating suspension.
2, the rubber flame-retarded property of topping is better.
3, have excellent resistance to ag(e)ing with second third glue as the vibration isolating suspension of topping rubber, can prolong product application life.

The specific embodiment
Referring to Fig. 1 ~ 2, Fig. 1 is the structural representation of the fire-retardant vibration isolating suspension of the utility model.Fig. 2 is the stereogram of the fire-retardant vibration isolating suspension of the utility model.Can find out that by Fig. 1 and Fig. 2 the fire-retardant vibration isolating suspension of the utility model, said bearing are superposeed at interval with internal layer rubber 2 by steel plate 1 and constitute laminated construction, and coat layer protective layer rubber 3 in the outer rim of said laminated construction.Internal layer rubber coheres at inner and steel plate and constitutes bearing load and endergonic main body, and topping rubber is coated on outside the laminated construction of steel plate and internal layer rubber formation, forms the topping of layer of protecting internal construction.
Internal layer rubber is selected natural gum for use; In natural gum, add a certain amount of fire retardant; Fire retardant is selected for use BACN Doher-731 big with the intermiscibility of natural gum, good flame retardation effect, topping rubber is with second third glue and neoprene blended rubber, and second third glue has good resistance to ag(e)ing as protective layer material; Neoprene adds hydration zinc borate as flame-retardant materials in blended rubber.
During production; Internal layer rubber 2 and steel plate 1 one deck alternating floor are folded; Topping rubber 3 is coated on outside the laminated construction that steel plate and internal layer rubber constitutes, accomplishes the preformed work of neoprene bearing, preformed bearing is placed in the mould sulfidization molding under the heating and pressurizing effect of vulcanizing press.
Claims (1)
1. fire-retardant vibration isolating suspension is characterized in that: said bearing by steel plate (1) and internal layer rubber (2) at interval stack constitute laminated construction, and coat layer protective layer rubber (3) in the outer rim of said laminated construction.
