Particularly its high rigidity and wearability, even if being also held essentially constant at a temperature of 500 DEG C, still have the highest when 1000 DEG C
Hardness.Hard alloy is widely used as cutter material, such as lathe tool, milling cutter, planing tool, drill bit, boring cutter etc., for cutting cast iron, has
Non-ferrous metal, plastics, chemical fibre, graphite, glass, stone material and common iron, it is also possible to be used for cutting stainless steel, high temperature alloy, high hard
The difficult to machine material such as steel, titanium alloy.Hard alloy, during being processed into cutter, needs to utilize forming agent extruded,
Current pressing material mainly controls squeeze pressure by the method adding secondary solvent, but solvent has added many can increase glutinous
Property, after molding, shape keeps poor；In existing forming agent system, solvent is the best with plasticising constituent element dissolubility, segregation phenomena easily occurs,
Cause unstable product quality；The organic solvent that in the most existing extrusion molding agent technique extruded stock, residual volatile is low, dries in the shade
Time is long, uses drying mode crackle easily occur, and forming agent volatility is poor, and the easy stagnant knot of forming agent, at product surface, is unfavorable for the moon
Do or dry.
Summary of the invention
It is an object of the invention to overcome the deficiency of prior art, it is provided that one can flash baking hard alloy forming agent

A. it is by above-mentioned forming agent premixing；
B. the forming agent after cemented carbide powder and premixing is carried out heated sealed mixing, make forming agent and hard alloy
Powder mix homogeneously.
The present invention has selected paraffin to be plasticizer, and paraffin is to evaporate from some of oil, shale oil or other Colophonium mineral oil
Going out a kind of hydrocarbon mixture extracted in thing, main component is solid alkane, odorless, tasteless, for white or faint yellow semi-transparent
Bright solid.Paraffin is noncrystal, but has obvious crystal structure.
The present invention has selected oleyl amine to be activator.
The present invention has selected soybean oil to be lubricant, and soybean oil is a kind of oil that squeezing extracts from Semen sojae atricolor, has
Preferably lubricity.
The present invention has selected normal octane to be solvent, and normal octane is a kind of colourless transparent liquid.
The present invention is soybean oil and the volatility introducing on the basis of paraffin extrusion forming agent technique and having lubrication
Moderate solvent constituent element i.e. normal octane；By the introducing of lubricity constituent element, can while reducing the overall dosage of forming agent
Ensure that pressing material reaches extruded plasticity requirements, it is to avoid the increase of forming agent causes follow-up removing difficulty and crackle quality wind
Danger；The solvent constituent element moderate by introducing volatility, makes spice process more stable, and uniformity improves, and subsequent extrusion base is cloudy simultaneously
Do faster, it is also possible to realize flash baking.
Compared with prior art, the invention has the beneficial effects as follows:
Present invention introduces soybean oil lubricant component, by conservative control plasticising constituent element and the ratio of solvent constituent element, give and squeezing
The pressure preferable plasticity of feeding and viscosity, it is ensured that the excellent base after extruding has preferably dimension shape performance；By introducing solvent normal octane,
Normal octane and existing solvent phase ratio, have a good intersolubility to the forming agent of paraffin systems, mixing after not have forming agent inclined
Analysis phenomenon；Normal octane volatility simultaneously is moderate, has ensured the stability of spice, can realize quickly drying in the shade or drying.
Hard alloy spice technique based on above-mentioned forming agent, uses heated sealed calendering process, it is not necessary to evacuation.
The present invention is that one can be applicable 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, shortens the manufacturing cycle of extruded product.
Below in conjunction with embodiment, the present invention is described in further detail；But the one of the present invention can flash baking hard
