Abstract
The invention belongs to precision casting technology fields, disclose a kind of hot investment casting Wax particles mould material and preparation method and application.Mould material of the present invention includes the component of following mass fraction：Pertroleum wax 50~70%, animal wax 0~10%, mineral wax 10~15%, vegetable wax 0~15%, Petropols 0~15%, toughener 0~10%, ultra-violet absorber 0~5 ‰, antioxidant 0~10 ‰.Oil wax stock stabilization is easy to get, the present invention greatly reduces the cost of printing wax powder material using pertroleum wax as raw material, increase toughness, intensity, hardness by adding animal wax, mineral wax, vegetable wax, Petropols, toughener etc. simultaneously, so that mould material viscosity, fusing point are low, good fluidity, granular materials causes transport and easy to process.No rosin formula ensures that casting wax can repeatedly use, and environment compatibility is good, while simple for process, improves work efficiency, reduces cost, have a vast market prospect and the market competitiveness.
Description
Technical field
The invention belongs to precision casting technology field, more particularly to a kind of hot investment casting Wax particles mould material and preparation method thereof
With application.
Background technology
Model casting is also referred to as precision-investment casting, using lost-wax process as casting method, using final products as copy, by wax-pattern
Material is pressed into accurate cast model, and refractory material is then applied on wax-pattern；Shell is formed after slurry dry solidification, then
It is sky that the wax-pattern solidified in shell is melted and casting wax is made to flow out to obtain internal by the methods of being demoulded by high-temperature steam or hot water
Cavity；By manufactured hollow shell high temperature sintering, remove other substances of shell interior and make shell further firm, dry
It is dry；The metal target solution to conform to quality requirements is injected in shell；Liquid metal solidification cooling after shelling, cleaning (in case with
After use), obtain accurate bright and clean casting.Hot investment casting need not be processed too much after a kind of mould material casting is molded, through meticulous
The casting technique that small processing can be used directly, precision-investment casting application range is wider, by the obtained casting of this method
Part has the characteristics that precision size degree is high, form is accurate, surface roughness is low, and high-end casting is with the obvious advantage.
The waxy materials that hot investment casting uses are mainly hot investment casting wax, and hot investment casting wax belongs to special wax scope, be with
It is reconciled based on pertroleum wax.China is the country of pertroleum wax production and outlet maximum, but China's special wax starting evening, special
Kind cerul this dependence import.China is compared with World Investment Casting level, and essence casting is also using the aviation essence of first kind technique productions
Casting output is very few, and the precision castings of high quality are also few, is largely pipe fitting of less demanding, hardware, auto parts etc., mainly
The reason is that China lacks the high-end hot investment casting wax of voluntarily development ＆ production.
Hot investment casting wax development in recent years is also very fast.Patent CN106084806A is disclosed to be based on graphite oxide modified rosin
Hot investment casting wax and preparation method thereof, wherein hot investment casting wax include 20%~30% modified rosin, 50%~65%
Paraffin, 5%~10% tackifier, 5%~10% PE waxes and 0%~3% lignite wax；Patent CN106046807A is public
A kind of high thermal stability hot investment casting wax-pattern material opened includes 10~16 parts of microwax, 9~12 parts of terpene resin, ethylene-vinyl
6~10 parts of alcohol copolymer, 10~15 parts of Brazil wax, 18~25 parts of paraffin, 5~12 parts of candelila wax, 1,3- oxazas
4~6 parts of hexamethylene；The casting wax based on ceresine that patent CN105537510A is announced includes 100 parts of ceresine, microwax 7
~20 parts, lignite wax 25~28, EVA 20~24,1,3- oxazas hexamethylene 4~6, octadecanoid acid 10~14, calcium stearate
0.2~1.2；A kind of hot investment casting wax-pattern material that patent CN104759587A is announced includes 40~60% microwax, 5~30%
Terpene resin, 5~30% PE waxes, 0~30% Brazil wax, 0~10% candelila wax, patent
CN104841880A announce a kind of hot investment casting medium temperature modulation wax include 44~46 parts of microwax, 2.5~3.5 parts of lignite wax,
34~36 parts of rosin resin, 3.5~4.5 parts of ethylene-vinyl acetate copolymer, 12~14 parts of pure monomer resin.Traditional precision
Casting wax-pattern material is used cooperatively with several in paraffin, stearic acid and rosin, although plasticity and Packing character are good, is stablized
Property, intensity difference, these inventions on the basis of traditional hot investment casting wax using microwax, rosin, EVA resin resin as raw material carry out
It reconciles so that the hot investment casting wax performance of preparation improves a lot, but because the presence of rosin has larger problem, containing rosin
Base-material easily aoxidized in fusion process, generate carcinogen, to user have larger harm, simultaneously as the change of rosin
Matter can cause mould material to become sticky, and be unfavorable for operating.
Larger shrinking percentage is a principal element for influencing hot investment casting wax performance, is shunk to reduce hot investment casting wax
Rate, condiment are a common methods.Patent CN106280502A, CN105945222A, CN104972063A,
CN102876054A etc. discloses the content being adjusted using filler.Cause mould material in preparation because adding in excessive filler
Wax pattern surface quality has larger impact, while intensity is poor, easily cracks.It is more difficult when casting loses wax step, while ash
Divide height.
Hot investment casting classical method as manufacturing tradition, researching and developing high performance precision casting wax energetically can not only
The development of hot investment casting industry and special wax industry is promoted, while abundant economic value can be brought.
The content of the invention
In order to overcome the shortcomings and deficiencies of the prior art described above, primary and foremost purpose of the invention is to provide a kind of hot investment casting
Wax particles mould material.Mould material intensity of the present invention is high, hardness is big, fusing point is low, ash content is small, shrinking percentage is small.
Another object of the present invention is to provide a kind of preparation method of above-mentioned hot investment casting Wax particles mould material.
