Description
Technical field:
The present invention relates to a kind of analog material and preparation method thereof, especially a kind of test materials that is applicable to the imitating shell plastic material.
Background technology:
The analog simulation test is by certain how much, physical relation, replaces prototype to carry out testing research with model, and result of study is used for the test method of prototype.It is a kind of important scientific research means, be in the laboratory, to make the model similar to prototype by similarity principle, by the force parameter and the regularity of distribution thereof in the testing instrument observation model, the result that utilization is studied on model, so as to contingent mechanics phenomenon and rock mass pressure distribution rule in the deduction prototype, thus the practical problems in the production of solution rock mass engineering project.This research method has directly perceived, easy, economical, quick and advantage such as the test period is short.And can be as required, by fixing some parameter, changing other parameters and study stress rule over time in the actual engineering, these all are difficult to realize under the condition at the scene.
In the geotechnical engineering scientific research, often relate to the correlation theory research of elastic-plastic material, ideal plastic-elastic stress-strain curve concerns or the elastic-plastic material with stress reinforced stress-strain curve relation all is the important tests material that carries out theoretical investigation and have, therefore, it is necessary developing this material.And yet there are no the report of developing similar test material with ideal elastic-plastic stress-strain curve.
Summary of the invention:
Technical problem: the purpose of this invention is to provide a kind of elastoplasticity analog material that can satisfy similar test and geotechnical engineering theoretical investigation and preparation method thereof.
Technical scheme: elastoplasticity analog material of the present invention, adopting paraffin, Vaseline and powdered rubber is raw material, is prepared from through mixing, its quality proportioning is as follows:
100 parts in paraffin;
50～120 parts in Vaseline;
20～100 parts of powdered rubbers.
The preparation method of elastoplasticity analog material of the present invention is as follows:
(1) takes by weighing paraffin, Vaseline and powdered rubber by the quality proportioning;
(2) earlier Vaseline and paraffin are put into container, put into the baking oven thawing of heating again;
(3) treat that Vaseline and paraffin all melt to behind the liquid, take out container solution is stirred 1～2min, slowly add powdered rubber then, continue to be stirred to evenly;
The liquid compound that (4) will stir injects mould, and the normal temperature about 24h curing of cooling down promptly obtains the elastoplasticity analog material.
The described melt temperature of heating is 80～140 degrees centigrade.
Beneficial effect: the present invention adopts paraffin and Vaseline as consolidating material, and powdered rubber is a filler, by different quality proportionings, just can obtain to have the ground analog material of ideal elastic-plastic stress-strain behavior and stress reinforced stress-strain behavior; This strength of materials is lower, is convenient to the loading in the model trial, and small-sized loading equipemtn just can; This material can be realized recycling, and stable mechanical property has been reduced experimentation cost greatly.Its starting material source is wide, is highly susceptible to processing, does not need maintenance, and mechanical property is at room temperature more stable, can be used for simulating the ground elastic-plastic material, helps solving the practical problems in the rock mass engineering project production.Because the paraffin that adopts in the material is solid at normal temperatures, Vaseline is sticking semi-solid state, and both are by heating, when being higher than about 70, temperature just can be changed into liquid state when spending, just can add the material of batch mixes Cheng Xin this moment therein, removes hot conditions again, but just cooling forming under the room temperature.Its preparation method is simple, cheap, practical.
