Optional, said bonding agent each component percentage by weight is: medical paraffin 17%, ceresine 21%, high density polyethylene (HDPE) 30%, EVA resin 32%; Can reach the bonding agent proportioning of optimum performance.
Optional, said bonding agent each component percentage by weight is: medical paraffin 13%, ceresine 18%, high density polyethylene (HDPE) 43%, EVA resin 26%; The bonding agent proportioning that cost performance is the highest.
A kind of carboloy nozzle manufacturing approach may further comprise the steps successively:
A. after cemented carbide powder and bonding agent being mixed, put into two roller rubber mixing machines, under 170～190 ℃ temperature mixing repeatedly 2～3 hours, obtain the carbide alloy feeding;
B. the carbide alloy feeding that obtains in the steps A is placed in the injection (mo(u)lding) machine, under the condition of 25～35 ℃ of 130～150 ℃ of injection temperatures, injection pressure 50～70MPa, mould temperature, be processed into the carboloy nozzle blank;
C. then the carboloy nozzle blank among the step B is put into three polyethylene solutions, 45～55 ℃ temperature held 7～8 hours, dissolve, degreasing, take out dry then;
D. dried blank among the step C is put into vacuum drying oven, vacuum 5Pa, 1400～1450 ℃ of temperature, sintering time 1～2 hour with the stove cooling, obtains carboloy nozzle then.
Preferably, the temperature in the said steps A in the two roller rubber mixing machines is 180 ℃, mixing time 2.5 hours; Can access quality carbide alloy feeding preferably.
Preferably, 140 ℃ of injection temperatures among the said step B, injection pressure 60MPa, mould temperature are 30 ℃; Guarantee the quality of blank.
Preferably, the carboloy nozzle blank is put into three polyethylene solutions among the said step C, the temperature held of 50 ℃ of temperature 8 hours, dissolves, degreasing; To blank dissolve fully, degreasing, remove partial supplementary material.
Preferably, dried blank is put into vacuum drying oven among the said step D, 1430 ℃ of temperature, sintering time 1.5 hours; Can access the sintering parameter of top-quality nozzle.
Compared with prior art, advantage of the present invention is: if the feeding injections difficult that the ratio of medical paraffin less than 10%, is then processed; Be unfavorable for formed product, if ratio greater than 17% then the feeding of processing does not have rigidity, shaped article is too soft; Deflection is big, influences product quality, and the characteristics of EVA resin are to have good flexibility; Elasticity as the rubber, owing in strand, introduced VAM, thus reduced high-crystallinity; Improve pliability, impact resistance, filler intermiscibility and heat seal performance, do not contained solvent, free from environmental pollution and security is higher, be very suitable for the streamline production of automation; The EVA resin content is lower than 20% can make the viscosity easy-formation not inadequately of making carboloy nozzle, the EVA resin content be higher than 32% can make the nozzle injection moulding again the time too thickness be not easy to automated production; Adopt technique scheme to become the carboloy nozzle abrasion resistance of output strong, the stability and the uniformity of injection are higher, and the life-span is long, and production cost is effectively reduced.
The specific embodiment
Embodiment one:
A kind of carboloy nozzle; Comprise cemented carbide powder, bonding agent; The volume ratio of said cemented carbide powder and bonding agent is 7: 3; Said bonding agent comprises following component, and each component is by weight percentage: medical paraffin 10%, ceresine 15%, high density polyethylene (HDPE) 55%, EVA resin 20%.
Embodiment two:
A kind of carboloy nozzle; Comprise cemented carbide powder, bonding agent; The volume ratio of said cemented carbide powder and bonding agent is that 5: 5 said bonding agents comprise following component, and each component is by weight percentage: medical paraffin 17%, ceresine 21%, high density polyethylene (HDPE) 30%, EVA resin 32%.
