Abstract
The invention relates to a durable sealing rubber which is prepared from the following raw materials in parts by weight: 8-14 parts of nitrile-butadiene rubber, 2-6 parts of reinforcing agent, 2-6 parts of zinc borate, 4-8 parts of montmorillonite, 3-5 parts of dioctyl phthalate, 4-6 parts of calcium carbonate, 7-10 parts of isoprene rubber, 2-5 parts of silane coupling agent, 1-4 parts of sodium nitrate, 1-3 parts of silica white and 1-6 parts of naphthenic hydrocarbon. The durable sealing rubber has the advantages of excellent elasticity and favorable sealing effect, and can be used as a sealing gasket, seal ring or the like.
Description
Technical field
The present invention relates to a kind of durable caulking gum.
Background technology
Rubber is a kind of resilient polymkeric substance.Rubber can obtain from the myron of some plants, also can be artificial, and both considerable application and product, such as tire, packing rings etc., become Important Economic crop then.The plantation of rubber mainly concentrates on south east asia, as Thailand, Malaysia, Indonesia.Rubber is divided into natural rubber and synthetic rubber by raw material.Block rubber, latex, fluid rubber and powdered rubber is divided into by form.Latex is the colloidal water dispersion of rubber; Fluid rubber is the oligopolymer of rubber, is generally the liquid of thickness before unvulcanized; Powdered rubber be latex is processed into Powdered, in order to batching and processing and fabricating.The thermoplastic elastomer of the exploitation sixties in 20th century, without the need to chemicure, and adopts the working method of thermoplastics to be shaped.Rubber is divided into again universal and Special type two class by use.Be isolator, be not easy conduction, if but get wet or different temperature, likely become conductor.
Summary of the invention
For the deficiencies in the prior art, the problem to be solved in the present invention is, provides a kind of durable caulking gum, and have excellent elasticity, good sealing effect, can do gasket, sealing-ring etc.
For solving prior art problem, technical scheme provided by the invention is, a kind of durable caulking gum, and it is made up of the raw material of following parts by weight:
Paracril 8-14 part, strengthening agent 2-6 part, zinc borate 2-6 part, polynite 4-8 part, dioctyl phthalate (DOP) 3-5 part, calcium carbonate 4-6 part, synthetic polyisoprene 7-10 part, silane coupling agent 2-5 part, Sodium Nitrite 1-4 part, white carbon black 1-3 part, naphthenic hydrocarbon 1-6 part.
The invention has the beneficial effects as follows: durable caulking gum of the present invention, have excellent elasticity, good sealing effect, can do gasket, sealing-ring etc.
