In substratum transparent after hardening, the unconsolidated core section preparation is obtained；Wherein, in the step S30 and the step S50
In, encapsulating processing is carried out using transparent resin adhesive.
The production method for the unconsolidated core section preparation that the technical solution of first aspect present invention provides, first to unconsolidated core
It is dried, causes subsequent clear resin glue to be difficult to permeate downwards to avoid excess moisture, then use transparent resin adhesive to dry
Unconsolidated core after dry carries out encapsulating processing so that loose unconsolidated core can be formed by curing slice, then use transparent resin
Glue carries out encapsulating processing to slice so that slice is inlayed in substratum transparent after hardening, is sliced so as to form unconsolidated core
Sample.Since transparent resin adhesive has stable physical and chemical performance, because prepared by unconsolidated core section preparation, both ensure that loose
The integrality of core sample will not lose all structures that should possess on unconsolidated core slice, structure detail, have higher section
Value is ground, the accuracy for every experimental test and analysis establishes strong basis；And unconsolidated core is completely enclosed within transparent tree
It in fat glue, is not influenced by the temperature of external environment, humidity and human factor, physico-chemical property is constant, is conducive to long-term preservation, energy
Enough accurate original rock core is provided for later scientific research needs；Meanwhile the transparent performance that transparent resin adhesive is excellent, significantly optimize
The appearance of unconsolidated core section preparation convenient for carrying out 360 ° omni-directional observation and description to unconsolidated core, and improves loose rock
The class of heart section preparation is very suitable for externally putting on display.
In addition, the production method in above-mentioned technical proposal provided by the invention can also have following additional technical feature：
In the above-mentioned technical solutions, the step S50 is specifically included：The slice is put into mold by step S504, and
Keep the displaying of the slice face-up；Step S506 pours into the transparent resin adhesive into the mold, makes the transparent resin
Adhesive curing forms the substratum transparent；Step S508 removes the mold after setting time, obtains the unconsolidated core slice mark
This.
In the technical scheme, by selecting displaying of the top and bottom than more visible, smooth and complete one side as slice
Displaying is put into mold and carries out encapsulating again, on the one hand further encapsulated to the display surface by face up, on the other hand, avoids
Slice to the destruction of display surface, ensures clarity, planarization and the integrality of display surface during demoulding, convenient to loose rock
The heart carries out comprehensive observation and description.
In the above-mentioned technical solutions, it is preferable that in the step S506, the transparent resin adhesive that is poured into the mold
Height be more than the slice upper surface 3mm-5mm；And/or in the step S508, the setting time is 6h-8h.
In the technical scheme, it is more than the upper surface of slice by the height of the transparent resin adhesive poured into step S506
High definition in the range of 3mm-5mm, both avoid transparent resin adhesive it is very few cause solidification after the excessively thin cause of substratum transparent
The case where making to cause slabbed core to leak outside when follow-up sanding and polishing, in turn avoiding transparent resin adhesive excessively causes after curing
The blocked up observing effect for influencing unconsolidated core of substratum transparent.Certainly, different molds, size are not quite similar, and are put into mold
The thickness of slice be also not quite similar, so the amount for pouring into the transparent resin adhesive in mold in the actual production process can also root
It is adjusted according to needs.
In step S508, in the range of the hardening time of transparent resin adhesive is limited to 6h-8h, when both having avoided solidification
Between it is too short cause transparent resin adhesive curing is incomplete to happen, in turn avoid the hardening time long system for leading to section preparation
The case where making excessive cycle occurs.Certainly, different transparent resin adhesives, ingredient are not quite similar, so setting time is not limited to
In above range, can be adjusted as needed in the actual production process.
In any of the above-described technical solution, after the step S50, further include：Step S60, to the unconsolidated core
Section preparation carries out sanding and polishing processing, keeps the surface of the unconsolidated core section preparation smooth.
In the technical scheme, by carrying out sanding and polishing to unconsolidated core section preparation, unconsolidated core can be made to be sliced
The surface of sample is smooth, so that unconsolidated core section preparation is more transparent, bright, so both so that being encapsulated in sample
Internal unconsolidated core is more clear vivid, facilitates look at interior details, has higher scientific research value, further optimize
The appearance of unconsolidated core section preparation, further improves the class of section preparation.
In any of the above-described technical solution, the step S60 is specifically included：Step S602, using sander by the pine
The surface for dissipating slabbed core sample polishes flat；Step S604, the displaying using polishing machine to the unconsolidated core section preparation
Face is processed by shot blasting.
In the technical scheme, sander is first used to carry out grinding process to the surface of section preparation, when grinding process
Stock removal is relatively large, can quickly polish excessively rough position on section preparation, can greatly shorten subsequent
Polishing time, so as to shorten the fabrication cycle of section preparation；Since section preparation is normally only there are one display surface, so only need pair
Display surface is processed by shot blasting, is also beneficial to shorten fabrication cycle in this way, is saved cost of manufacture.
In the above-mentioned technical solutions, it is preferable that in the step S602, successively use 150 mesh, 500 mesh, 1000 mesh,
1500 mesh, 2500 mesh sand paper grinding process is carried out to the surface of the unconsolidated core section preparation.
In the technical scheme, in grinding process technique, the effect of the mesh number of the sand paper of selection and its sequence to grinding process
Fruit and processing time influence very big, and the technical staff of our unit has paid a large amount of performing creative labour, by test of many times and
It is found after research, uses the sand paper of 150 mesh, 500 mesh, 1000 mesh, 1500 mesh, 2500 mesh to unconsolidated core section preparation successively
When surface carries out grinding process, more excellent polishing effect can be obtained using the relatively short time.Certainly, different to cut
Piece sample, concrete condition are not quite similar, so the sand paper mesh number and sequence selected can be adjusted as needed.
In any of the above-described technical solution, when the thickness of the slice is less than or equal to preset thickness, in the step
Before S504, further include：Step S502, the transparent resin adhesive of the first setting of side coating thickness, makes institute in the mould
It states transparent resin adhesive semi-solid preparation and forms isolation glue-line on the inner surface of the mold.
In the above-mentioned technical solutions, the preset thickness is 0.5cm-1.5cm, and described first sets thickness as 1mm-3mm.
In the technical scheme, before to slice encapsulating processing, layer of transparent resin glue first is coated in die inside, thoroughly
Isolation glue-line can be formed after bright resin glue semi-solid preparation on the inner surface of mold, isolation effect can be played to mold, in this way,
After slice is put into mold, it can avoid mold directly to the destruction of slice；And demoulding when, isolation glue-line it is possible to prevente effectively from
Unconsolidated core slice is bonded on the inner wall of mold so that the demoulding of unconsolidated core section preparation is more convenient；It ensure that simultaneously
The surface of unconsolidated core section preparation is smooth, reduces the working strength of subsequent sanding and polishing step；In addition, insulation rubber
Layer, which can be bonded together with the slice being put into mold and finally cure, is integrated depanning together, it ensure that slice is comprehensive
It is encapsulated in transparent resin adhesive, without local leakage, thus is conducive to the long-term preservation of section preparation.
Preferably, in the range of preset thickness being limited to 0.5cm-1.5cm (such as 0.5cm, 1cm, 1.5cm), it is convenient for
Final section preparation controls in suitable thickness range, can either preferably show internal structure, and be unlikely to excessively stupid
Weight.
The thickness of the transparent resin adhesive of coating is 1mm-3mm (such as 1mm, 2mm, 3mm), and both having avoided blocked up leads to wave
Take, in turn avoid it is excessively thin cause it is uneven and easy to operation；And in the step, the semi-solid preparation time of transparent resin adhesive is 2h-4h
(such as 2h, 3h, 4h), so both so that transparent resin adhesive is unlikely to be placed into the slice buckling of mold with certain hardness
Shape also avoids slice and infilters in transparent resin adhesive, to ensure that the planarization of slice surface, in turn ensures transparent resin adhesive
It can be integrally formed depanning together with slice bonding after being fully cured.
In any of the above-described technical solution, when the thickness of the slice is more than preset thickness, in the step S30 and institute
Between stating step S50, further include：Step S40 carries out encapsulating processing to the slice, after slice solidification, is cut to described
Piece carries out reduction processing；Alternatively, step S40 ', reduction processing is carried out to the slice；Wherein, in the step S50, to subtracting
The slice after thin carries out encapsulating processing.
In the technical scheme, it when the thickness of slice is more than preset thickness, can both be expended when carrying out encapsulating processing to it
Excessive transparent resin adhesive, and hardening time can be extended, and be easy to keep finally obtained section preparation blocked up, it is unfavorable for encapsulation and protects
It deposits, also influences presentation quality.Therefore, it when the slice thickness obtained after the processing of first encapsulating is more than preset thickness, needs to it
Reduction processing is carried out, final encapsulating is then carried out again and inlays, so that unconsolidated core section preparation after final molding
Thickness control in a certain range, is conducive to the preservation of unconsolidated core section preparation, saves transport and memory space.
Wherein, the unconsolidated core for quality than relatively soft easy cutting finishing is sliced (such as sand class slabbed core), can
Directly to be modified using pocket knife, reduction processing is carried out to it, it may be necessary to use cutting machine, but cannot will be after solidification
Core surface destroys；And for the more relatively hard loose class slabbed core for being not easy cutting of quality, (such as clay class rock core is cut
Piece), in order to avoid destroying slice when reduction processing, encapsulating processing need to be carried out again to it, keep unconsolidated core solidification more complete,
To avoid destruction slice surface or internal structure when reduction processing.
In the above-mentioned technical solutions, when the production method further includes step S40, the step S40 is specifically included：Step
Rapid S402 makes the transparent resin adhesive semi-solid preparation in mould in the transparent resin adhesive of die inside coating the second setting thickness
Isolation glue-line is formed on the inner surface of tool；The slice is put into the mold by step S404, and makes slice encapsulating
Flat down；Step S406 pours into the transparent resin adhesive into the mold, and the slice surface is made to form third setting
The substratum transparent of thickness；Step S408, removes mold, and reduction processing is carried out to the slice；Step S410, to it is described be sliced into
Row grinding process keeps the surface of the slice smooth；When the production method further includes step S40 ', in the step
In S40 ', reduction processing is carried out to the slice using cutter or cutting machine.
In the above-mentioned technical solutions, the preset thickness is 0.5cm-1.5cm；And/or in the step S402, institute
It states second and sets thickness as 1mm-3mm；And/or in the step S406, the third sets thickness as 0.5cm-1cm；
And/or in the step S408, reduction processing is carried out to the slice using cutting machine；And/or in the step S410
