Abstract
The invention discloses a kind of molds for preparing high polymer dynamic viscoelasticity test test specimen, box body (1) including compression molding, the box body includes side wall (2) and bottom wall (3), and rectangle cavity (4) are provided on the bottom wall.The present invention can be used for preparing high polymer dynamic viscoelasticity test test specimen, and manufacturing cost is low, convenient to use, high yield rate, small with size difference between batch test specimen.
Description
(1) technical field
The present invention relates to a kind of molds, and in particular to a kind of mold for preparing high polymer dynamic viscoelasticity test test specimen.
(2) background technique
Viscoplasticity is an important performance of high polymer, it makes polymer material while having the viscosity and solid of fluid
Elasticity.Polymer is usually to become fluid (melting and flowing) from solid, then from fluid to become solid (cold in process
But and harden), but the gradually property of the backbone and macromolecular movement due to the high-polymer molecule, the deformation and flowing of polymer are not
It is pure elasticity or pure viscosity, so polymer shows the response of stress to have pair of solid and fluid concurrently in process
Principal characteristic matter, that is, show viscoplasticity.Such as viscoplasticity makes plastics while having the characteristic of similar solid, such as elasticity, intensity, stabilization
Property, and the characteristic of similar fluid, the flowing such as changed with temperature, payload and rate.
Viscoplasticity the physical mechanics of polymer and processing performance are influenced it is great, the viscoplasticity of polymer by duration of load application,
Frequency, the influence of temperature are very big.Therefore, the new type rubber, resin, plastics of research and development and its modification and composite material require to detect
Viscoplasticity.Currently, people generally use dynamic thermomechanical analysis apparatus (DMTA (IV)) to detect the viscoplasticity of high polymer.Material
The chain structure and state of aggregation of secondary relaxation process and polymer are closely related.When the chemical composition of polymer, branching and crosslinking, knot
When the structural factors such as brilliant and orientation change, it can all be reflected on DMTA (IV) dynamic mechanical spectrogram.DMTA (IV) is right
The test of the dynamic viscoelastic of high polymer has become movement and its structure and theory of a kind of Study Polymer Melts strand
Important means.
The conventional method that people prepare high polymer dynamic viscoelastic test test specimen at present is to weigh a certain amount of deployed material
Material, which is placed in culture dish, beaker or self-control simple die, to be solidified, then sawing is at the test specimen of specification.This method time-consuming is taken
Power, and high polymer after solidifying is easily broken in sawing and cracking, yield rate is low, and test specimen surrounding is not neat, between batch test specimen
Size difference is big.In addition, certain polymer reactions and solidification after stiffly condense on the wall, cause container be difficult cleaning and
Recycling, causes very big waste.For this purpose, applicant's Binding experiment room demand, develops the technical program.
(3) summary of the invention
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of manufacturing cost is low, convenient to use, institute
What size difference was small between test specimen processed prepares the mold of high polymer dynamic viscoelasticity test test specimen.
Technical solution provided by the invention is as follows:
A kind of mold preparing high polymer dynamic viscoelasticity test test specimen, comprising: the box body of compression molding, the box body packet

The mold of the present invention for preparing high polymer dynamic viscoelasticity test test specimen, as the improvement of technical solution,
The cavity of the rectangle cavity is cuboid, having a size of 30~40mm of length, 8~15mm of width, 2~5mm of height.Cavity ruler
Very little, quantity is depending on the size of box body and actual needs.
In any one above-mentioned technical solution, the mold for preparing high polymer dynamic viscoelasticity test test specimen,
Its described side wall is equipped with flanging, and flanging is bent to the outside of box body.
In any one above-mentioned technical solution, the mold for preparing high polymer dynamic viscoelasticity test test specimen,
Its described box body and flanging are conjoined structure.
In any one above-mentioned technical solution, the mold for preparing high polymer dynamic viscoelasticity test test specimen,
It can be fabricated to various different sizes and specification according to specific needs.
Mold of the invention is used to prepare high polymer dynamic viscoelasticity test test specimen, has the advantages that
Mold made of the present invention, the box body including compression molding, box body includes side wall and bottom wall, and is provided on bottom wall
