Abstract

The invention relates to a test method for simulating ageing of an O-shaped rubber sealing ring in marine environment. The method comprises the following steps: applying a pressure to the rubber sealing ring, carrying out salt spray treatment, and carrying out high temperature treatment. The method fully considers the influences of salt spray on the corrosion ageing of rubber under the marine environment conditions, and also considers the ageing test carried out after application of the practical use stress to the O-shaped rubber sealing ring, so the method has careful, scientific and reasonable conception.

Description

A kind of simulate RUBBER O RunddichtringO aging testing method under marine environment
Technical field
The present invention relates to the aging testing method of a kind of rubber, particularly relate to a kind of simulate old under marine environment of rubber Change test method, belong to accelerated degradation test technical field.
Background technology
Elastomeric material and goods thereof, due to its unique, excellent performance, have been widely used in oil, building, automobile, boat It etc. multiple fields.Use test method to carry out ageing of rubber research and can specify ageing of rubber rule and mechanism, and can predict In its service life, the natural aging of rubber typically requires the time of several years, hence with quick aging method to carry out rubber material The aging research of material becomes a kind of practical ways.
At present conventional quick aging method have hot-air accelerated ageing, oxygen bomb accelerated ageing, artificial climate accelerated ageing, Damp and hot accelerated ageing, ozone accelerated ageing etc., in place of the most conventional ageing of rubber experimental technique comes with some shortcomings: one, Existing ageing of rubber experimental technique does not considers the ageing of rubber under salt air corrosion effect；Its two, RUBBER O RunddichtringO use During by bigger stress effect, and can test about the ageing of rubber under stress condition and rarely have report.
Summary of the invention
The present invention is directed to the deficiency that existing ageing of rubber test method exists, on the basis of traditional high temperature ageing, increase Add salt fog and answer force conditions, it is provided that a kind of simulate RUBBER O RunddichtringO aging testing method under marine environment.
The technical scheme is that
A kind of simulate RUBBER O RunddichtringO aging testing method under marine environment, it is characterised in that include walking as follows Rapid:
1) select the elastomeric material used by sealing ring, be processed into rubbery sample；
2) use compression clamp that sample is applied stress, make sample deform upon, compression ratio 20%～40%；
3) compression clamp and sample being placed in salt spray test chamber, temperature is set to 30～40 DEG C, sinking of NaCl saline solution Fall rate is 1～3ml/ (80cm2H), retention time 48h；
4) compression clamp and sample are put into constant temperature ageing oven carries out degradation, enter under the conditions of 120～200 DEG C Row degradation, the persistent period is 7～14 days；
5) take out sample, place 1～3 hour under free state, treat that sample recovers height, calculate rubber according to equation below The compression set rate of sample
K = h 0 - h 2 h 0 - h 1
In above formula, h0It it is height before sample compression；h2It is that sample recovers height；h1It it is the height of compression clamp.
Further, step 1) described in elastomeric material be cyaniding butyronitrile.
Further, the processing dimension of described rubbery sample is φ 9.5mm × 10mm.
Further, described step 3) in salt spray test chamber temperature be set to 35 DEG C.
Further, described step 4) in persistent period of degradation be 7 days.
Further, described step 5) in place 1 hour under free state.
The invention has the beneficial effects as follows: the present invention has taken into full account under marine environmental conditions, salt fog is to rubber corrosion and ageing Effect；Consider and carry out degradation after RUBBER O RunddichtringO is applied actually used stress；Conceive careful, scientific and reasonable.
