Described balancing weight is the polylith derby of adjustable weight.
Method for making sample of the present invention is as follows:
After resin such as step 7 grade solidifies fully, remove counterweight, take off the leather sample that is cured;
The resin that modulates 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 that contains 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, contains available oxygen≤10%.
Beneficial effect of the present invention is as follows:
The present invention can well remain after the fiber condition of leather when stretching solidified by resin-dipping, the state while understanding tensile fiber by its cross section of observation after being convenient to.Use unsaturated polyester resin, promoter and curing agent mixture dipping leather sample, because 196# unsaturated polyester resin viscosity is little, intensity is high, be easy to soak into leather, strong with leather affinity, be made into a kind of firm polymer matrix composites after curing, leather fiber is fixed, can polish to it, the operation such as polishing, and fiber do not move, indeformable, do not lack.
