Abstract
The invention belongs to the field of aeronautical material testing, and in particular relates to a method for preparing a standard test piece for a tensile test of a GPS-2 silicon rubber liquid. The method comprises the following steps of: mixing the GPS-2 silicon rubber liquid, primarily flattening, overlapping standard test plates and vulcanizing. The method is simple and convenient to operate, and a used die which is made of a steel material is unlikely to deform when being pressurized and shaped, so that the uniformity of the thickness of the standard test piece is ensured; silica oil is replaced by a polyvinyl chloride film, so that the influence of artificial factors on controlling the silica oil coating uniformity and coating quantity is avoided; and after the test piece is vulcanized, the polyvinyl chloride film can be easily uncovered, so that the completeness of the standard test piece after the film is eliminated is ensured, the surface defect is avoided, the quality of the test piece is ensured, and the accuracy of test result is improved. The time interval from the moment that the GPS-2 silica rubber matrix and a curing agent is mixed to the moment that the film is prepared is explicitly provided, so that the influence that too much solvent is internally supplied and air is wrapped in stirring because of the too short time interval is avoided.
Description
Technical field
The invention belongs to aeronautical material test field, particularly relate to a kind of GPS-2 silastic liquid tension test standard test piece preparation method.
Background technology
The GPS-2 room temperature vulcanized silastic adhesive mixes the back by basic glue, hardening agent ratio in accordance with regulations and solidifies, and is used for glueing joint.In the testing of materials, need it is carried out the tension test of pulling strengrth, breaking elongation.In the existing tension test, the sample production process is: adopt the plastic foil tool, mould of plastics is smeared silicone oil with hairbrush; After the ratio mixing in accordance with regulations of GPS-2 room temperature vulcanized silastic adhesive base glue, hardening agent, load in mould of plastics, good mould of plastics is superimposed with loading, and pressurization is cured.Distortion appears easily in the mould of plastics that uses in the test in pressure process, cause the stretching standard test piece for preparing in uneven thickness; And because pressure can not be excessive, cause test piece fine and close inadequately, there are defectives such as bubble inside, and then influences the accuracy of stretch test result.Smear silicone oil in the test in the mould of plastics, prevent that GPS-2 room temperature vulcanized silastic adhesive and mould of plastics are bonded together, and play the effect of release agent.But silicone oil disperses at specimen surface easily, causes defectives such as the little hole of specimen surface; Simultaneously, the homogeneity that silicone oil is smeared in mould of plastics and to smear consumption wayward is not applied to the part demoulding difficulty of silicone oil, is prone to surface damage during skinning.
Summary of the invention
Goal of the invention: a kind of GPS-2 silastic liquid tension test standard test piece preparation method is provided, can improves the sample preparation quality.
Technical scheme:
A kind of GPS-2 silastic liquid tension test standard test piece preparation method may further comprise the steps:
The mixing of step 1, GPS-2 silastic liquid: mixed base glue, curing agent component to scale, under standard environment, place 30min;
Step 2, preliminary flattening-out: take by weighing mixed GPS-2 silastic liquid 50g～60g, place between two polyvinyl chloride films, mixed GPS-2 silastic liquid and polyvinyl chloride film are put into steel mould together, preliminary flattening-out forms the standard test plate (panel);
Step 3, standard test plate (panel) superimposed: several standard test plate (panel)s alignment are piled up, put the steel cover plate topmost, standard test plate (panel) and steel cover plate periphery align;
Step 4, sulfuration: the standard test plate (panel) after superimposed is put into press together, exert pressure gradually with lifting jack, standard test plate (panel) periphery is overflow behind the glue, pressurize is to stipulating cure time;
The tension test standard test piece is taken out in step 5, release, throws off polyvinyl chloride film.
Preferably, the regulation ratio described in the step 1 is according to batch decision of material.
Preferably, the standard environment described in the step 2 is 23 ± 2 ℃ of temperature, humidity 50 ± 5%.
Preferably, it is characterized in that the regulation cure time described in the step 4 is 5-7 days.
Beneficial effect: this method is simple to operation, and the mould that uses is steel material, and is not yielding when extrusion forming, and this has just guaranteed the homogeneity of standard test piece thickness; Steel die is compared with mould of plastics can bear bigger pressure, and the standard test piece densification of guarantee making, level and smooth reduces the probability that defective such as bubble appears in standard test piece inside.This method uses polyvinyl chloride film to replace silicone oil, the human factor influence of having avoided control silicone oil to smear homogeneity and smear consumption fully; Test piece can be thrown off polyvinyl chloride film like a cork after sulfuration, guaranteed the integrality of standard test piece behind the demoulding, has avoided surface imperfection, has guaranteed the quality of test piece, has improved accuracy of experimental results.This method is mixed the back to GPS-2 silastic liquid base glue, hardening agent and has been carried out clearly stipulating to the time interval of film processed, avoid the too short internal solvent that causes of the time interval too much to reach when stirring and entrained into air influence, and the long problem that the film forming difficulty occurs of the time interval.
Embodiment
Below the present invention is done describing in further detail, a kind of GPS-2 silastic liquid tension test standard test piece preparation method may further comprise the steps:
The mixing of step 1, GPS-2 silastic liquid: under standard environment, mixed base glue, hardening agent stir with glass bar to scale, place 30min under standard environment.Pay special attention to the control of standing time, the time is too short, and mixed GPS-2 silastic liquid solvent is higher, is difficult for sulfuration, and the air brought into when stirring of glue inside formation air blister defect during easily at film processed; Standing time is long, surpasses its working life, will cause being difficult for the problem of film forming.Can needle tangible air pocket with finer wire herein.The blending ratio of base glue and hardening agent is determined according to the material of different batches.
Step 2, preliminary flattening-out: take by weighing mixed GPS-2 silastic liquid 50g～60g, place between two polyvinyl chloride films, mixed GPS-2 silastic liquid and polyvinyl chloride film are put into steel mould together, use the preliminary flattening-out of waddy smooth, even thickness.Steel die, mixed GPS-2 silastic liquid and polyvinyl chloride film form the standard test plate (panel);
Step 3, standard test plate (panel) superimposed: can prepare a plurality of standard test plate (panel)s simultaneously, to increase work efficiency.Several standard test plate (panel) alignment are piled up, put the steel cover plate topmost, each standard test plate (panel) and steel cover plate periphery align, and avoid occurring receiving the generation of unbalance stress phenomenon between each standard test plate (panel) when pressing;
Step 4, sulfuration: the standard test plate (panel) after superimposed is put into press together, exert pressure gradually with lifting jack, standard test plate (panel) periphery is overflow behind the glue, strike off the periphery glue that overflows, pressurize is to stipulating cure time; Cure time, curing temperature are very big for the cure efficiency influence, and cure efficiency is best at normal temperatures, the auto-vulcanization condition can guarantee GPS-2 silastic liquid base glue, hardening agent progressively, fully reaction, make the standard test piece integrally stretching performance homogeneous of preparation.
The tension test standard test piece is taken out in step 5, release, throws off polyvinyl chloride film.
Preferably, the standard environment described in the step 2 is 23 ± 2 ℃ of temperature, humidity 50 ± 5%.
Preferably, it is characterized in that the regulation cure time described in the step 4 is 5-7 days.
