Abstract
A sealing elastomer material reinforced by non-asbestos fibres is prepared from adhesive, reinforcing fibres, inorganic filler, sulfurizing agent, antioxidant, plasticizer, sulfurization promoter, active agent and colouring agent through refining adhesive, pre-treating reinforcing fibres, mixing, shaping and sulfurizing. Its advantages are higher tension strength, proper compression percentage, better rebound resilience and anti-loosening power, and high resistance to high tmep and medium.
Description
The present invention relates to a kind of rubber-based sealing material and preparation technology thereof, the preparation technology of particularly a kind of non-asbestos fiber enhanced rubber packing material and compressed moulding thereof.
As everyone knows, sealing to national economy all departments energy-saving and cost-reducing, reduce environmental pollution etc. and play crucial effects.In the last hundred years, paronite sealing sealing material with its range of application, excellent comprehensive performance and cheap price widely, is used widely in engineering practice, and has been formed bigger industry size and wide application market always.But along with developing rapidly of modern industry production, particularly twentieth century 70 was carried since generation, and to the pollution of environment and the serious harm of HUMAN HEALTH, advanced industrial country is in succession to asbestos with contain asbestos products and forbidden or limit use for asbestos.The eighties rises, the U.S. (1986), Denmark (1986), Australia (nineteen ninety), Norway (1991), Italy (1992), Sweden (1992), Britain (1992), Germany (1993), Switzerland (1994), France's priorities such as (1996) have been worked out and have been forbidden or limit production and use asbestos and the decree that contains asbestos products, comprise traditional asbestos seal material.In view of to the production that contains the asbestos seal material and the restriction of use, conventional seals material produce factory begins exploitation, development in succession for the asbestos seal material, and the development and application of no asbestos seal material becomes active, the most outstanding innovative technology in Seal field in the recent two decades.Enter after the nineties, advanced industrial country launches respectively rules such as " Clean Air Acts ", requirement to air quality in human lives and the Working environment is more and more higher, the what is called in past " does not have and leaks " requirement and upgraded to severeer " no loss " (Non-Fugitive Emmision) requirement, these have all greatly promoted the new development of gasket material and manufacturing technology, and novel non-asbestos seal Development of Materials and application have been taken off in the effort of searching asbestos substitute especially greatly.
More and more higher to the requirement of non-asbestos seal material in view of each branch of industry, domestic main sealing material production unit has been developed part non-asbestos seal material.But,, comprise that also aspects such as production cost, complete processing and range of application can't substitute the paronite sealing material fully at some material property.
The objective of the invention is: provide a kind of with non-asbestos fiber enhanced sealing elastomer material and be compressed into the technology of sheet material, make it have better tensile strength, suitable rate of compression, compression recovery performance and the loose ability of creep resistance preferably, and have advantages such as resistance toheat is good, medium-resistance is good, can substitute traditional asbestos rubber sealing material in the use range more widely.
Technical scheme of the present invention is: a kind of with non-asbestos fiber enhanced sealing elastomer material, comprise binding agent, fortifying fibre, inorganic physique filler and vulcanizing agent, anti-aging agent, softening agent, vulcanization accelerator, promoting agent, tinting material, its component and weight ratio are:
