Description
Technical field
It the utility model is related to rubber hardness detection technique field, and in particular to a kind of to be used to detect mixing of rubber hardness
Sample.
Background technology
In rubber process, as the hardness determination of elastomeric compound, GB/T531.1 is based on《Vulcanize rubber or thermoplasticity rubber
Glue laminated enters hardness test method》Part 1：Shore durometer method, existing latest national standards time 2008.In GB/T531.1-
In 2008 standards, clear stipulaties sample requirement：The distance between sample thickness, number of checkpoints, test point and point, test
The distance of point and edge.In this standard, the concrete shape of sample to be checked is not prescribed by.
The performance detection of elastomeric compound, is based on GB/T528《Vulcanize rubber or thermoplastic elastomer tensile stress-strain performance
Test》, test sample defines specific thickness and shape, sees Fig. 3.In rubber process, the control of final end properties
It is the control in advance to semi-finished product glue (i.e. elastomeric compound).In China's rubber enterprise, the detection of elastomeric compound hardness is not because have
Specific shape is provided, so most enterprises are all for convenience of tensile stress-strain sample is used, that is, does elastomeric compound hardness test
Performance test is done again.Needing to be superimposed 3 ability but existing tensile stress-strain sample both ends are big, middle small, during test expires
The requirement of sufficient sample thickness, can not also meet required distance between test point simultaneously in addition, can not single-time measurement multiple spot take intermediate value.
In the prior art, both do not meet the hardness determination requirement of elastomeric compound also, and meet single-time measurement again, quickly and easily rubber is hard
Degree measure sample.
Utility model content
In view of this, the application provides a kind of sample for being used to detect mixing of rubber hardness, and the sample makes without superposition
With, there is clear and definite test point, it is simple in construction, it can easily test the hardness of mixing of rubber.
To solve above technical problem, technical scheme provided by the utility model is a kind of for detecting mixing of rubber hardness
Sample, the sample includes round platform, and 5 test circles being arranged on the round platform, the thickness of the round platform are not less than
6mm, during 5 tests are round, the edge spacing of adjacent test circle is not less than 6mm, the edge and the round platform of any test circle
The spacing at edge be not less than 12mm.
By above technical scheme, truncated cone-shaped will be arranged to for detecting the sample of mixing of rubber hardness, and define circle
It the thickness of platform, can only need one piece of sample to meet the thickness requirement of hardness determination without superposition, while be set on round platform
5 test circles are put, disclosure satisfy that carrying out 5 measurements in specimen surface diverse location takes the requirement of intermediate value, while also define survey
The spacing of spacing and test circle and round platform edge between examination circle, can realize the disposable completion detection of sample hardness.This
Apply for design of the technical scheme by sample, disclosure satisfy that the testing requirements of rubber hardness, one piece of sample can be used to complete inspection
Survey, used without being superimposed, have clear and definite test point, while improve the accuracy and detection efficiency of detection.
Further, the thickness of the round platform is 6.2mm.
Further, in 5 tests circle, the external diameter of each test circle is 6mm.
Further, in 5 tests circle, the internal diameter of each test circle is 5.5~5.8mm.
Wherein, the internal diameter and external diameter of 5 test circles are defined, 5 test circles are arranged to have certain thickness circular hole
Shape, scleroscopic placement when being easy to hardness determination, while also disclosure satisfy that measure requires.
Further, 5 tests circle is above the round platform plane and is no less than 0.2mm.Define that 5 are tested circle
Highly, it is easy to scleroscopic placement, meets that measure requires, improve detection accuracy.
Further, in 5 tests circle, including 1 first test circle and 4 second tests are justified, and described first surveys
The center of circle of examination circle overlaps with the center of circle of the round platform, and the 4 second tests circle is distributed in the first test circle surrounding.By 5
Individual test circle is arranged to the 1 first test circle in the middle part of round platform and 4 test circles positioned at the first test circle surrounding, to circle
Space rational deployment distribution on platform, meets the requirement of distance between 5 test circles, meets to carry out in specimen surface diverse location
5 measurements take the requirement of intermediate value.
Further, the center of circle of the 4 second tests circle is distributed on circumference of the radius not less than 12mm.By 4
Second test circle is distributed on same circumference, when meeting test, the spacing of any one second test circle and the first test circle
It is identical, and the spacing round with the first test is 6mm, can meet different test positions two-by-two at a distance of 6mm.
Further, the diameter of the round platform is not less than 55mm.The diameter of round platform is limited, can be made on test circle in office
When being tested, it can meet test position apart from least 12mm requirement of round platform edge.
Based on described above, compared with prior art, its advantage is the application：(1) one piece of sample can only be needed
The thickness requirement of hardness determination can be met without superposition；(2) it disclosure satisfy that and carry out 5 measurements in specimen surface diverse location
Take the requirement of intermediate value；(3) testing requirements of rubber hardness are disclosure satisfy that, detection is completed using one piece of sample, used without being superimposed；
(4) accuracy and detection efficiency of detection are improved.
