The method for making sample of described device is as follows:
Step 3 adds resin by mould openings in mould, when the resin added reaches the leather sample height, and stops the resin of annotating after soaking into leather fully;
Step 4 covers upper holder block, and makes the lower lock block alignment.
Step 6 continues the filling resin, and the top of resin and upper holder block top are maintained an equal level;
Resin such as step 7 grade removes acting force or removes counterweight after solidifying fully;
After step 8 is rapped mould, from pushing notch of barge by the leather sample that is cured from mold ejection;
The resin modulated in described step 6 comprises 196# unsaturated polyester resin, cobalt iso-octoate solution, methyl ethyl ketone peroxide solution, and its ratio is the 196# unsaturated polyester resin: cobalt iso-octoate solution: methyl ethyl ketone peroxide solution=100:1:1.2.
Described cobalt iso-octoate solution is every milliliter of solution containing cobalt iso-octoate 0.40～0.45 gram; Described methyl ethyl ketone peroxide solution is every milliliter and contains methyl ethyl ketone peroxide 0.54～0.60 gram, containing available oxygen≤10%.
Principle of the present utility model is to use unsaturated polyester resin, promoter and curing agent mixture dipping top to stretch leather sample, be made into a kind of firm polymer matrix composites after solidifying, leather fiber is fixed, can be polished to it, the operation such as polishing, and fiber do not move, indeformable, do not lack.
The beneficial effects of the utility model are as follows:
Sample preparation device described in the utility model, it is constant that in the resin-dipping solidification process, power is stretched on top, and 196 resin viscosities are little, and intensity is high, and sticky good with property with leather, the upper and lower briquetting of resin does not take out, and fiber condition well remains after solidifying by resin-dipping.State while after being convenient to, by its cross section of observation, understanding fiber compression; Owing to adopting the split inclined mould, and bottom is provided with demoulding pushing notch of barge, is convenient to the demoulding; Because pressure is adjustable, can obtain the sample under various pressure, applied range.In addition, this apparatus structure is simple, is easy to make, easy to operate.
