Abstract
The present invention relates to an epoxy resin cementing method for preparing rock specimen sheet. Said method includes the following steps: preparing liquid cement by using epoxy resin adhesive component A and epoxy resin adhesive component B according to a certain mixing ratio, heating and removing bubbles from liquid cement, using the above-mentioned liquid cement to join the rock specimen to glass sheet, at the same time removing bubbles, after the liquid cement is solified, cutting specimen and grinding so as to obtain the invented rock specimen sheet.
Description
Technical field
The invention belongs to the sample disposal technology in stratigraphy, petrology and the petrifactology, relate to a kind of epoxy gluing method of rock flaking.
Background technology
Becoming transparent slide (common name " thin slice ") to study on rock or paleontological fossil preparation of specimen, is research form commonly used in many subjects such as petrology, petrifactology, and the making of sample thin slice is one of technology that often adopts in the sample disposal.Its method is that the thin slice with rock or paleontological fossil pastes on the glass sheet (slide glass) with specific adhesive (glue), then with machinery and the manual thickness that needs that this thin slice is ground to, perhaps cutting to regrinds behind the certain thickness is thinned to the thickness (generally at 0.05mm to 0.03mm) that needs, be transparent or near-transparent, so that examine under a microscope research.Sometimes also on sample, add a cover " cover glass ".
Wherein bonding die is the important step of film-making work, and the quality quality of stickup directly influences the success or not that thin slice is made.And being chosen in this link of adhesive is crucial.The technical requirement of this adhesive is: cohesion is strong, transparency is high, colourless or thickness is hour colourless, index of refraction near glass, long-term storage do not chap, non-crystallizable, do not come unstuck.The bonding die glue of habitually practising in the conventional art is " canada balsam " that the resin modified of a kind of abies grandis tree is made, this is a kind of fragility glue of hot melt, its impact resistance extreme difference, particularly when lower temperature, be very easy to come unstuck, often have a strong impact on the success ratio of thin slice, very difficult especially competent for the sample of those particular lithologics.The cohesion of this glue is also not ideal enough.
In film-making work for frangible, too hard, or shale etc. special sample, develop and a kind of technology with cutting means instead of part grinding technology, be to cut thin " publishing in instalments the sheet cutting " behind the first bonding die, and this technology is higher to the requirement of adhesive, and traditional canada balsam is difficult to reach requirement.That adds a cover " cover glass " on the sample surface of thin slice often also will adopt same glue with glue, runs into same problem sometimes.
Summary of the invention
In order to solve the aforementioned problems in the prior, the present invention will provide a kind of new gluing method of rock flaking, and the impact resistance of the sample sheet that new method is cohered should be significantly improved, and is not acted upon by temperature changes; Cohesion also should be higher than conventional art, is not easy to produce degumming phenomenon in the operation, to improve the success ratio of thin slice.
The scheme of finishing the foregoing invention task is:
The epoxy gluing method of rock flaking, step is as follows:
Ratio preparation glue according to epoxide-resin glue AB component;
Heating is also got rid of the interior bubble of glue;
Cohere sample and slide with above-mentioned glue, get rid of bubble simultaneously;
After glue solidifies, immediately to sample cutting and wear down.
The present invention compares with conventional art, and main is not both: the character of epoxide-resin glue is different fully with Canadian resin glue, gets rid of the bubble step so need increase by one in glue preparation back; Simultaneously, because the cohesion of epoxy resin is far longer than conventional resins glue, thus must after solidifying, cut and wear down sample immediately by glue, otherwise the effect of stress may destroy glass slide.
This programme further improves, and following prioritization scheme is arranged:
When getting rid of in the glue bubble behind the preparation glue, the temperature of heating glue is controlled at 60～80 ℃, and the time was controlled at below 5 seconds, helped the eliminating of bubble, and is little to influence set time simultaneously.
Described epoxide-resin glue preferably adopts the bright epoxide-resin glue of full impregnated of three A series cold curing.
The new gluing method of rock flaking provided by the invention, it is poor to have solved in the prior art canada balsam impact resistance, the problem of coming unstuck easily, the impact resistance of new method is significantly improved, and is not acted upon by temperature changes; Cohesion also should be higher than conventional art, has improved the success ratio of thin slice.Simultaneously, owing to realized publishing in instalments the sheet cutting, even hard and frangible sample can directly switch to desirable thinness, the labour intensity when reducing wear down has improved work efficiency.
Embodiment
Embodiment 1, grinds the technology of thin slice with the GH-AAA sheet adhesive, and step is as follows: epoxide-resin glue adopts commercially available GH-AAA glue, according to the ratio preparation glue of GH-AAA glue AB component; Heating is also got rid of the interior bubble of glue, and the temperature of heating glue is controlled at 60～80 ℃, and the time was controlled at below 5 seconds, helped the eliminating of bubble; Cohere sample and slide with above-mentioned glue, get rid of bubble simultaneously; After glue solidifies, immediately to sample cutting and wear down.
Find that by testing us the transparency of this glue is very good.Index of refraction except that the minority mineral, satisfies the identification of Mineral of petrographic thin section a little more than canada balsam substantially, satisfies fully to be used for the paleontological fossil thin slice.Cohesive strength is supported our the final requirement that realizes publishing in instalments the sheet cutting fully.This breakthrough makes the rock sample of the lithology that original difficult mill maybe can not grind can wear into thin slice smoothly.
Use the method for operating main points of GH-AAA sheet adhesive:
1, since the having relatively high expectations of AB component proportioning operate with balance as far as possible.
2, the glue bubble after the proportioning is more, when getting rid of bubble, can heat slightly on electric hot plate, and Controllable Temperature is built in 60-80 ℃, and the time was controlled at below 5 seconds, ends when the flowability of glue-line is best.
3, the grindability during this glue fine grinding is slightly poor, must scalp the surplus glue around the sample after bonding die is finished immediately.
4, this glue gel time shorter, as one man operation, should not once allocate excessive amount.Generally be advisable with the consumption of pasting the 10-15 sheet.
5, curing in 6-8 hour under this glue room temperature publish in instalments sheet cutting and wear down after the curing immediately, otherwise the effect of stress may destroy glass slide.
Claims (4)
1, a kind of epoxy gluing method of rock flaking, step is as follows:
Ratio preparation glue according to epoxide-resin glue AB component;
Heating is also got rid of the interior bubble of glue;
Cohere sample and slide with above-mentioned glue, get rid of bubble simultaneously;
After glue solidifies, immediately to sample cutting and wear down.
According to the epoxy gluing method of the described rock flaking of claim 1, it is characterized in that 2, when getting rid of in the glue bubble behind the preparation glue, the temperature of heating glue is controlled at 60～80 ℃, the time was controlled at below 5 seconds.
