The technical solution adopted by the present invention to solve the technical problems is：One kind being capable of the molding of flash baking hard alloy
Agent is grouped as by the group of following weight percentage, wherein：
A kind of hard alloy spice technique based on above-mentioned forming agent, includes the following steps：
It A. is to be pre-mixed above-mentioned forming agent；
B. heating is sealed to the forming agent after cemented carbide powder and premixing to be kneaded, make forming agent and hard alloy
Powder is uniformly mixed.
It is plasticizer that the present invention, which has selected paraffin, and paraffin is evaporated from petroleum, shale oil or the certain of other pitch mineral oil
A kind of hydrocarbon mixture extracted in object out, main component are solid alkanes, and odorless, tasteless is white or faint yellow semi-transparent
Bright solid.Paraffin is noncrystal, but has apparent crystal structure.
It is activator that the present invention, which has selected oleyl amine,.
It is lubricant that the present invention, which has selected soybean oil, and soybean oil is that a kind of oil extracted is squeezed from soybean, is had
Preferable lubricity.
It is solvent that the present invention, which has selected normal octane, and normal octane is a kind of colourless transparent liquid.
The present invention is that the soybean oil and volatility with lubricating action are introduced on the basis of paraffin extrusion molding agent technique
Moderate solvent constituent element, that is, normal octane；It, can while reducing the whole dosage of forming agent by the introducing of lubricity constituent element
It ensures that pressing material reaches the plasticity requirements of extrusion forming, the increase of forming agent is avoided to cause subsequent removing difficulty and crackle quality wind
Danger；By introducing the moderate solvent constituent element of volatility, keep spice process more stable, uniformity improves, while subsequent extrusion base yin
It does faster, can also realize flash baking.
Compared with prior art, the beneficial effects of the invention are as follows：
Present invention introduces soybean oil lubricant components to assign and squeeze by rationally controlling the ratio of plasticising constituent element and solvent constituent element
The preferable plasticity of feeding and viscosity are pressed, guarantees that bar stock after extruding has preferable dimension shape performance；By introducing solvent normal octane,
Normal octane has good intersolubility compared with existing solvent, to the forming agent of paraffin systems, is not in that forming agent is inclined after mixing
Analyse phenomenon；Volatility is moderate simultaneously for normal octane, has ensured the stability of spice, it can be achieved that quickly drying in the shade or drying.
Hard alloy spice technique based on above-mentioned forming agent, using heated sealed calendering process, without vacuumizing.
The present invention is that one kind can be applied to paraffin systems, balances volatility and spice stability, the molding of safety and environmental protection
Agent can realize flash baking while ensureing spice safety, stability, shorten the manufacturing cycle of extruded product.
Invention is further described in detail with reference to embodiments；But one kind of the invention being capable of flash baking hard
Alloy forming agent is not limited to the embodiment.
