Abstract

The invention discloses a thermal-insulation adhesive for die-forging of forge pieces, which is used for forming die forging pieces and especially suitable for thermal-insulation forming of high-temperature alloy, titanium alloy and aluminum alloy die-forging pieces. The adhesive for thermal-insulation materials can form a continuous, uniform and compact film for thermal insulation and lubrication on the surface of a forge piece. The adhesive disclosed by the invention is prepared from the following components in percentage by weight: 20-40% of organosilicon heat-resistant resin or organic titanium epoxy resin, 20-40% of glass powder, 0-5% of trisodium phosphate, 2-6% of anhydrous borax, 0-5% of graphite, 1-3% of leafing aluminum paste, 1-5% of magnesium aluminum silicate suspending agentand 10-40% of xylene. The invention can accurately control the forging temperature, reduce the number of times of blank returning, prolong the forgeable time each time, lower the cost of the used coating materials, widen the optional range of the thermal-insulation coating materials, and the like. Meanwhile, the invention also provides a preparation method of the thermal-insulation adhesive.

Description

technical field [0001] The invention relates to the technical field of die forging. It can be used not only for general die forgings, but also as an adhesive for thermal insulation forming of high-temperature alloys, titanium alloys and aluminum alloy die forgings used in large and complex aviation and aerospace equipment. Background technique [0002] Forging, especially the thermal insulation material in the die forging process plays a key role in the product forming. The thermal insulation material for die forging with excellent performance can not only ensure the smooth progress of die forging, but also prolong the life of the die and improve the forming quality of the workpiece. Countries around the world have done a lot of research on this, and have formed technical methods to achieve heat preservation with coating materials, mainly including the "hard sheath" method and the "soft sheath" method. [0003] "Hard sheath" method, that is to use copper plate or ordinary st...
