Abstract
The present invention belongs to a reinforced cork rubber pad made of the compound mixed material of cork rubber, which is formed by adding 60 to 120 parts by weight of cork particle and 5 to 50 parts by weight of reinforced fibrous material in 100 parts by weight of vulcanized section material. The present invention has high compression resistant strength by a reinforced sleeper pad made of the compound mixed material, a shock absorption pad and an expansion joint strip material; moreover, the tensile strength and the extrusion resistant strength are largely enhanced. The reinforced cork rubber pad is mainly used for the shock insulation materials of the sleeper pad, an electromechanical device instrument, an aquatic zoo and a cultivation farm, the telescopic materials and the heat insulation materials of a building, a road, an airport runway, a square, a bridge hole and a water dam.
Description
Technical field
The present invention relates to a kind of improvement of rubber blanket, particularly with rubber make railroad sleeper pad or similar products such as sealing gasket.
Background technology
Rubber, cork-rubber, resin cork are respectively applied for mechanical vibration damping sealing gasket, building expansion joint bar etc. several years history, all has excellent sealing performance, rubber exists easily aging, and other materials exists tensile strength lower, the disadvantage of breaking easily in flight-line maintenance.Simultaneously, railroad tie is used instead after the concrete crosstie, for reducing vibration, increase a flexible sleeper under sleeper, and this sleeper uses the gum material to manufacture usually, and the one, aging easily, and make intensity relatively poor.For improving the ageing of rubber problem, Chinese patent 93217752.2 has proposed a kind of cork-rubber sleeper pad, and it is evenly distributed on the cork particle in the rubber and constitutes.But this utility model patent does not fundamentally solve the problem of the pull resistance difference of sleeper.
Summary of the invention
The present invention is intended to utilize the ageing resistance of cork and the pull resistance of fibrous material, strengthens the ageing resistance and the intensity of Rubber sleeper pad and sealing gasket.
Specifically, strengthen the cork-rubber pad, it is to be made by the reinforcing fibre material that adds 60-120 weight portion cork particle, 5-50 weight portion in the sulfidization molding material of 100 weight portions.
Described sulfidization molding material can be a kind of or any several mixture in natural rubber, synthetic rubber, PVC, the polyurethane.
Described reinforcing fibre material is one or more the mixture in glass fibre, wood-fibred, cotton fibriia, straw fiber or the fiber cloth.
The fortified resin cork adopts heat cure or the tiling hot-press solidifying of colding pressing of casing in the composite material of mentioned component, rubbery cork is taked mixing sulfuration process, the plastic cement cork takes injection moulding to go into the mould one-step moulding method, the resin cork expansion joint bar that strengthened respectively, cork-rubber, cork plastic cement, sleeper bolster and beam.
Can one-shot forming when adopting this composite material to make the sleeper pad, also can be compound one deck reinforcing fibre between two-layer composite material.
Powerful sleeper pad, beam, expansion joint strip material have following advantage among the present invention: the higher compression intensity that contracts is not only arranged, and the anti-extrusion extension strength of tension improves a lot.Cork plastic material Shooting Technique production efficiency is increasing substantially than rubber and sulfuration process intensity, and production efficiency improves, and product is strengthened performance and improved, and cost reduces.Be mainly used in the shock insulation material of sleeper pad, electromechanical device instrument, aquatic animal garden, plant, the telescopic material and the heat-barrier material of building, highway, airfield runway, square, bridge hole, dam.
Description of drawings
Sleeper pad and sealing gasket that Fig. 1 makes for material of the present invention.
Fig. 2 is the compound sleeper pad among the present invention.
The specific embodiment
Mix with the moulding material 1 (any or its mixture in resin, rubber and rubber TRR, the PVC plastic cement) of 100 weight portions, the cork particle 3 of 60-120 weight portion, 2 three kinds of compositions of fiber of 5-30 weight portion.Use resin cork sheet by the synthetic density 280-450kg/m3 thickness 2-5mm of cork Elastic plastic-rubber (rubber, resin, plastic cement), the plastic cement cork sheet, rubbery cork plate and fiber or fiber cloth 4 are taked bilayer or multi-layer compound structure.Stick with glue or vulcanization process strengthened sleeper pad, beam expansion joint bar.
