Abstract
The invention discloses a rubber damping product with an inner framework made of ultra-high molecular weight polyethylene. The rubber damping product is characterized in that plates made of the ultra-high molecular weight polyethylene serve as the main framework (1) and are disposed in a rubber damping product body (3), and the main framework (1) serves as a supporting structure of the rubber damping product. In order to improve bonding strength between the framework made of the ultra-high molecular weight polyethylene and rubber materials, the plates made of the ultra-high molecular weight polyethylene are in a hollowed-out design, in other words, the framework is provided with holes (2). The rubber damping product has the advantages of practical structure, impact resistance, good damping performance, light weight, convenience in mounting and maintenance, low cost and easiness in implementation.
Description
Technical field
The present invention relates to a kind of rubber damping product of built-in ultra-high molecular weight polyethylene skeleton, belong to rubber, plastic article and hardware fitting manufacturing technology field.
Background technique
Rubber damping product is widely used in various vehicle, boats and ships, machinery, instrument and apparatus, bridge, building, the material of main part of rubber damping product is main mainly with natural rubber, neoprene or ethylene propylene rubber, some other synthetic rubber also can be used under some have the condition of particular/special requirement, as: many employings nitrile butadiene rubber with oil resistant requirement, require the employing silicone rubber of high-low temperature resistant, employing butyl rubber requiring high damping etc.The high elasticity that rubber damping product mainly utilizes completely cuts off vibrations, absorbs and impacts, in order to eliminate or to slow down the adverse consequences of vibrations.Its molding mode many employings compression molding.Usually supporting or link is made.
Rubber damping product is according to the difference of its Environmental Conditions and pressure-bearing size, and its inner support frame adopting some, according to the shape of environmental requirement design framework used and the distributing position of skeleton, and framework material many employings metal foil is main.It is good, withstand voltage that metallic material has with the adhesiveness of rubber, the advantages such as good impact resistance, and its shortcoming is that weight of metallic materials is comparatively large, and the expense of metallic material is also higher, increases production, replacing, maintenance cost.
Summary of the invention
Technological scheme:
In order to solve the problem, the present invention adopts the skeleton of ultra-high molecular weight polyethylene board as rubber damping product, this scheme reduces the weight of rubber damping product, can ensure resistance to pressure and the impact resistance of rubber damping product.
The molecular weight of ultra-high molecular weight polyethylene board used in the present invention is 300 ~ 5,000,000, and density is 0.93 ~ 0.94g/cm
3, hardness is 60 ~ 80 Shao Er D, tensile strength>=30MPa, yield strength>=20MPa, flexural strength>=600MPa(23 DEG C), tension fracture elongation rate is 300 ~ 400%.
The molding mode of high molecular weight polyethylene board material skeleton adopts compression molding mode, arranges some holes in the surface of skeleton, is conducive to and being located by connecting of rubber base material.Hole can, when skeleton pattern is molded by the mold cavity machine shaping with column structure, also can adopt aft-loaded airfoil mode shaping, as: the machine shaping of machine drilling method.Can reprocess according to actual requirement.
Skeleton need in conjunction with entering in the rubber base material of anti-vibration article, and the present invention uses rubber product to produce the sulfidization molding technique usually adopted and realizes the location of skeleton in the rubber base material of anti-vibration article and combination.
beneficial effect:
Present invention achieves the application of ultra-high molecular weight polyethylene board in rubber damping product, decrease the weight of rubber damping product, reduce production cost, also ensure that rubber damping product has good withstand voltage, impact resistance simultaneously.
Below in conjunction with accompanying drawing, structure of the present invention is described further.

Embodiment
Embodiment: see Fig. 1, Fig. 2, the present invention is built-in ultra-high molecular weight polyethylene skeleton rubber anti-vibration article, forms primarily of skeleton 1, skeleton hole 2, rubber base material 3.
Built-in ultra-high molecular weight polyethylene skeleton rubber anti-vibration article is cubic shaped, and overall dimensions is long 600mm, wide 300mm, thick 100mm; Adopt 3 layers of skeletal structure, upper strata skeleton is apart from rubber covering 5mm, each layer skeleton interval 20mm.
Skeleton (1) has the hollow type design of skeleton hole (2), and rectangular board-like shape.Skeleton (1) is of a size of long 500mm, wide 260mm, thick 15mm; Surface skeleton hole diameter is 40mm, and pore quantity is 9, along its length and width direction Symmetric mean distribution.
The processing technology of built-in ultra-high molecular weight polyethylene skeleton rubber anti-vibration article is that rubber product produces the sulfidization molding technique usually adopted.The rubber base material used is extruded into the required unvulcanized adhesive tape semi-finished product having one fixed width and thickness after mixing, heat refining, then will hold the rubber-coated body material of ultra-high molecular weight polyethylene skeleton layering of hole successfully; Need will also fill up in ultra-high molecular weight polyethylene skeleton hole, tamp rubber base material time rubber-coated, and get rid of inner air; Put it into curing forming mold after rubber-coated body material, complete the machine shaping of built-in ultra-high molecular weight polyethylene skeleton rubber anti-vibration article at the temperature specified, time and pressure.
The built-in ultra-high molecular weight polyethylene skeleton rubber anti-vibration article of completion of processing, through pressure-bearing experimental test, can bear 50 tons/part, can meet the usage requirement of rubber damping product completely.
