Abstract
The invention relates to a binder which comprises the following components according to weight percentage: 15 percent to 25 percent of chlorinated polyethylene, 15 percent to 25 percent of polyformaldehyde, 3 percent to 10 percent of rubber, 20 percent to 30 percent of petroleum wax, 15 percent to 25 percent of Brazil wax (palm wax), 1 percent to 5 percent of stearic acid and 1 percent to 5 percent of epoxidized soybean oil. In the forming technique of metal powder, the binder can improve the strength of blank, reduce the damage of the blank and improve the finished yield and the production efficiency.
Description
Technical field
The present invention relates to the bonding used in a kind of metallic powder injection moulding process, specifically a kind of metallic powder injection molding adhesive.
Background technology
In metal powder forming, binding agent is as carrier.Metal-powder can be shaped smoothly by means of binding agent, and then binding agent is all removed (degreasing) by dissolution with solvents and heating.Different metal powder injection molded technology mainly is the difference of binding agent and defatting technology.Binding agent can influence particles of powder filling, reunion, batch mixing, rheological characteristics, shaping, degreasing, blank intensity, dimensional precision, product subsurface defect with final chemical ingredients.Thereby to the requirement of binding agent comprise flow characteristics, degreasing characteristic, manufacturing process and with the aspects such as interaction of metal-powder.
The problem that existing metallic powder injection molding adhesive mainly exists is: in the product process that existing binding agent processes, and the blank insufficient strength height that obtains, the quality percentage of resultant product is relatively low, and unsticking speed is slow, and production efficiency is low.
Summary of the invention
The objective of the invention is to develop a kind of metallic powder injection molding adhesive.
What the present invention will solve is the blank insufficient strength height that exists in the existing metallic powder injection molding adhesive processing, the problem that quality percentage is low, unsticking speed is slow and production efficiency is low.
The component of the binding agent that the present invention develops and weight percent are:
Chlorinatedpolyethylene 15%～25%
Polyoxymethylene 15%～25%
Rubber 3%～10%
Paraffin 20%～30%
Brazil wax (palm wax) 15%～25%
Stearic acid 1%～5%
Epoxy soybean oil 1%～5%
Binding agent of the present invention has following good performance: 1) flowability, and under forming temperature, viscosity is lower than 10Pa.s; In the forming process, temperature is little to viscosity influence, and when moving, viscosity changes rapidly cold, and the cooling back is firm and stable.2) cohesiveness with powder is good, and can not produce chemistry should.3) degreasing characteristic does not have corrodibility to product, low ash oontent, and decomposition temperature is higher than injection temperature, and body of powder can eliminate after reaching Stability Analysis of Structures fully.3) manufacturing process characteristics, production cost is low, and safe environmentally safe does not have volatility, the circulation heating properties is constant, good lubricating property, high strength and high rigidity, thermal conductivity height, and hot expansion system is low, dissolve each other with conventional solvent, molecular chain is shorter, not orientation.
In the metal powder forming, can improve the intensity of blank with binding agent of the present invention, reduce the breakage of blank, improve yield rate, and it has the characteristic that removes fast, the time of removing can reduce to about 12 hours.
Embodiment
The present invention will be further described below in conjunction with embodiment.
