Description
Technical field
The present invention relates to casting auxiliary Material Field, print the production method of resin particularly to a kind of aluminum casting 3D.
Background technology
In recent years, three-dimensional (3D) printing technique rises in developed country, and it is the most no longer concept product that 3D prints, entirely
Ball many companies are proposed individual's 3D printer, and it has started universal in life usually and has progressively promoted at industrial circle
Application.In April, 2012, Britain " economist " publishes the article and thinks, 3D printing technique will push away together with other Digitalisation Manufacture Mode
The realization of the dynamic third time industrial revolution.Traditional manufacturing technology is " subtracting material manufacturing technology ", and it is then " increasing material manufacturing technology " that 3D prints,
It has low cost of manufacture, the clear superiority such as with short production cycle.Traditional cast aluminium self-hardening resin adhesive system is by three component groups
Becoming, a component is polyhydric alcohol, and two components are polyisocyanate, and three components are catalyst, because it has excellent mobility, it is easy to
Either manually or mechanically back-up sand, surface roughness are good, and dimensional accuracy is high, and curing rate is fast, and the most uniform curing, thorough hardening is good,
The advantages such as after cast, core (type) collapsibility is good, and sand removal is very easy, so in cast aluminium industry always in occupation of leading position.
But, it is high that it there is also production cost in actual applications, and production process complex operation is easily generated pungent in casting cycle
White smoke, execute-in-place work human and environment is produced greatly harm.At present, the domestic production aluminum casting 3D that there is no prints
The enterprise of resin.
Therefore, develop a kind of stable chemical performance, be applicable to use 3D printing technique, production cost low, easy and simple to handle, to ring
It is that whole industry 3D molding sand prints the problem that industry is paid close attention to jointly that the aluminum casting 3D of border close friend prints resin material.
Summary of the invention
For existing tradition aluminum casting resin deficiency in terms of production cost and work efficiency and environmental conservation, this
Bright creativeness develop a kind of stable chemical performance, be applicable to 3D printing technique, production cost low, easy and simple to handle, to ring
The aluminum casting 3D of border close friend prints resin.
In order to solve above-mentioned technical problem, the technical solution that the present invention uses is:
A kind of aluminum casting 3D prints resin, it is characterised in that include following components: bisphenol b, phenol, acetaldehyde solution, isophthalic two
Phenol, furfuryl alcohol, formaldehyde, potassium hydroxide, coupling agent and aldehyde capturing agent.
Further, the mass percent of above component is respectively as follows: bisphenol b 2-8%, phenol 13-29%, acetaldehyde solution
0.5-1.5%, resorcinol 2-8%, furfuryl alcohol 45-65%, formaldehyde 7-13%, potassium hydroxide 1-3%, coupling agent 0.5-1.5% and catch aldehyde
Agent 0.5-1.5%.
Meanwhile, the invention provides a kind of aluminum casting 3D and print the production method of resin, it is characterised in that include following
Step:
(1) melted phenol, bisphenol b, formaldehyde, furfuryl alcohol are proportionally put in reactor, add acetaldehyde solution, open stirring,
Being passed through steam pressure 0.1-0.2MPa, reaction temperature is at 80-110 DEG C；
(2) in the polymer that step (1) produces, add furfuryl alcohol, be passed through steam, be incubated 1h-3h；
(3), after insulation 1h-3h, it is transferred to the distillating still that reduces pressure, at temperature 60 C-80 DEG C, vacuum 0.05MPa-0.095MPa bar
Under part, reduce pressure distillation dehydration 1h-2h；
(4) after distillation dehydration, it is added thereto to resorcinol and potassium hydroxide aqueous solution, is warming up to 100-130 DEG C, be incubated 1h-
3h；
(5) it is down to room temperature, adds furfuryl alcohol, aldehyde capturing agent and coupling agent and stir, obtain aluminum casting 3D and print resin.
Beneficial effects of the present invention is as follows:
1, this aluminum casting 3D prints resin and selects the raw material relatively mild to human body and production environment in process of production,
Decrease the health to execute-in-place workman and the injury of environment to the full extent, and production process is simple, easily operated.
2, this aluminum casting is stable with 3D printing resin property, and viscosity is low, and first intensity is high, and setting rate is fast, high temperature collapsibility
Good, cast cleaning is without by mechanically or manually, fundamentally solving the problem that aluminum casting sand removal is difficult.
3, main raw material(s) used by this aluminum casting 3D printing resin is cheap and easily-available, greatly reduces production cost.
4, this aluminum casting 3D printing resin is easy to use, has thoroughly broken away from traditional aluminum casting loaded down with trivial details by three components resin
Operating process and casting cycle in produce the phenomenon of white smoke, easy to use, casting cycle will not produce pollution ring
The harmful gas in border.
