Adhesive for powder injection forming and application method thereof
The invention discloses an adhesive for powder injection forming and a preparation method thereof. The adhesive comprises the following components in percentage by mass: 5-10% of liquid paraffin, 5-15% of naphthalene, 15-20% of solid paraffin, 10-20% of microcrystalline wax, 15-20% of carnauba wax, 15-30% of first high-molecular polymer, 10-20% of second high-molecular polymer and 1-5% of stearic acid. The first high-molecular polymer and second high-molecular polymer are selected from any two of polyethylene, polypropylene, polyacrylate and acrylonitrile-butadiene-styrene copolymer. The method comprises the following steps: after feeding materials of the adhesive, injecting a green compact, putting in a sintering furnace, and carrying out hot removal on the green compact in the furnace by heating to 600 DEG C at the rate of 2-5 DEG C/minute, thereby completely removing the adhesive; and heating for sintering according to the sintering technique, thereby obtaining the finished product. The adhesive has the advantages of simple and controllable degreasing process and high degreasing efficiency; and the degreasing process can not influence the quality of the green compact, and is clean and environment-friendly.
