MASS FOR MAKING PRINCIPAL PART OF REPRODUCTION DEVICE

摘要

The solution falls into the field of epoxide resins and ceramic manufacturing. The decrease in the weight and increase in the mechanical strength of the main part of duplicators is solved. The mass, according to the solution, can be prepared by homogenisation of 100 parts by weight of plasticised epoxide resins, 5 to 30 parts by weight of filling agents and 10 to 50 parts by weight of polyamine, polyaminoamide, modified and additive hardeners based on aliphatic amines. The whole space or the space, which is decreased by the space for the additional charging of the working surface from flexible epoxide, in the prepared female mould are filled by this not yet hardened composition and it is exposed to the hardening process at a temperature of 0 to 80 degrees C, to an of advantage 20 to 30 degrees C.
