Background technology：
Hard alloy be by refractory metal hard compounds and binding metal by powder metallurgical technique made of it is a kind of
Alloy material, there are a series of premium properties such as hardness is high, wear-resisting, intensity and toughness are preferable, heat-resisting, corrosion-resistant, now extensively
As various high-abrasive materials.Its production process be generally the producing of powder, the mixing of powder, the compacting of blank and shaping, sintering,
Post processing, the compacting of wherein blank are one of key links of hard alloy manufacture.When making blank, typically now all adopt
Produced with dry bag formula isostatic pressed rubber soft mode.Because mould must possess certain tensile strength and tearing strength, while not
Physics chemical action can occur with medium, be not easy to adhere to pressed compact, so dry bag formula isostatic tooling is typically from polyurethane, polychlorostyrene
Matrix material of the vinyl material as mould.
Polyurethane rubber mould is using relatively broad, but because the processing characteristics of polyurethane, its shrinkage factor can be with productions
Slightly changing for technique and have larger fluctuation, and it is influenceed, tensile strength during long-term storage by moisture in air
It can be declined to a great extent Deng key performance, have a strong impact on the quality of product.Polyvinyl chloride mould is due to its matrix material polyvinyl chloride
The material property of itself, mould elasticity is general poor, and the product appearance after shaping is poor, and size is irregular, and processing capacity is big, serious shadow
Ring the benefit to enterprise.Simultaneously because cemented carbide powder cost is higher, the defects of rubber mold quality, can be caused not toward contact
Appreciable loss.It is necessary that this is improved.
By patent retrieval and do not find there be the patent literature constructed with the present invention, related to the present invention is main
Have following：
1st, Patent No. CN99114708, the patent of invention of entitled " preparation method of soft mould of natural rubber ", the patent
Disclose a kind of preparation method of soft mould of natural rubber, it be by natural rubber and altax, Vulcanization accelerator TMTD, zinc oxide,
After the complete mixing of antioxidant A W, sulphur, casein, ammoniacal liquor, potassium hydroxide and distilled water stirs, equably smear or be sprayed on
On duplicate, removed after dry.Soft mode, which is made, with the present invention had both had technique simple, low manufacture cost and elasticity good etc. excellent
Point, there is stretch-proof, tear-proof, abrasion performance, warping strength and endurance again, service life is grown, at normal temperatures can
Made, the soft mode especially suitable for the glass fiber reinforced plastics product of tack extra-heavy makes.
2nd, Patent No. CN200510132686, the patent of invention of entitled " method of manufacture soft mode ", the patent disclose
A kind of method for manufacturing soft mode, wherein the size regardless of the master mold for forming soft mode, process matching degree are all very high.
Method for manufacturing soft mode includes：Master mold is placed on fixture；Pre-polymer layer is formed in the fixture；Backplane substrate is attached
In the pre-polymer layer；Optionally solidify the pre-polymer layer to be formed selectively polymeric layer；From the fixture
The polymeric layer and the pre-polymer layer are peeled off with the master mold；And remove uncured pre-polymer layer.
3rd, Patent No. CN200710104859, the patent of invention of entitled " soft mold and its manufacture method ", the patent
Disclose a kind of soft mold and its manufacture method.The soft mold includes：Photocurable materials；And light trigger, wherein, it is described soft
Mould meets formula, wherein, γ dM are the scattered items of the surface energy of the soft mold, and γ pM are the surface energies of the soft mold
Polarity item, and γ L are the surface energies of deionized water.
Though these above-mentioned patents have been directed to the manufacture method of some soft molds, wherein having also related to some materials
Improvement, especially first patent（CN99114708）Propose a kind of method and glue that soft mode is prepared using natural rubber
Material, but this method proposed it is simply a kind of by natural rubber and altax, Vulcanization accelerator TMTD, zinc oxide, antioxidant A W,
After the complete mixing of sulphur, casein, ammoniacal liquor, potassium hydroxide and distilled water stirs, equably smear or be sprayed on duplicate,
Removed after dry straightforward procedure, this method is not adapt to make hard alloy soft jelly mould, the material proposed
Also it is not suitable with and makes hard alloy, therefore it is still necessary to is improved.

It can reach 2000 according to hard alloy dry bag formula isostatic pressed rubber soft mode, service life made from inventive formulation
More than secondary.
It can be seen from above-described embodiment that the present invention relates to the rubber soft mode of a kind of compacting of hard alloy blank and shaping
Preparation method, be kneaded using natural rubber and butadiene-styrene rubber or butadiene rubber, and accordingly adjust formula system, made after vulcanization
Go out the rubber soft mode of the compacting of hard alloy blank and shaping.
Further, described is to use natural rubber and fourth using natural rubber and butadiene-styrene rubber or butadiene rubber mixing
Benzene rubber or butadiene rubber are kneaded uniformly with zinc oxide, stearic acid, auxiliary addition agent in banbury, are added and are promoted in mill
Hard alloy blank rubber soft mode is made in agent, vulcanizing agent, then overall vulcanization.
Further, the preparation method of described rubber soft mode is as follows：
4）Choose dispensing：
Natural rubber 55-100 parts
Butadiene-styrene rubber 0-45 parts
Butadiene rubber 0-45 parts
Zinc oxide 3-5 parts
Stearic acid 1-3 parts
Auxiliary addition agent 53-130 parts
Age resistor 1-4 parts
Reinforcing agent 50-100 parts
Plasticizer 0-20 parts
Vulcanizing agent 1-3 parts
Accelerator 1-3 parts
5）Natural rubber and butadiene-styrene rubber or butadiene rubber and zinc oxide, stearic acid, auxiliary addition agent are mixed in banbury
Refining is uniform, and accelerator, vulcanizing agent are added in mill.
6）The rubber soft mode of the compacting of hard alloy blank and shaping is made in vulcanization.
The advantage of the invention is that：The present invention is using natural rubber and with a small amount of butadiene-styrene rubber or butadiene rubber, and phase
Vulcanizing system should be adjusted, it is the standby isostatic pressed soft mode poor dimensional stability of main system, use that can solve with polyurethane, polyvinyl chloride
The deficiencies of short life.Dry bag formula isostatic pressed rubber soft mode dimensional stability of the present invention based on natural rubber is high, elasticity is good,
Tensile strength is high.The hard alloy dry bag formula isostatic pressed rubber soft mode prepared according to inventive formulation uses under hydraulic pressure environment
When, service life may be up to 2000 times, remote ultra-traditional polyurethane, polyvinyl chloride hard alloy dry bag formula isostatic pressed rubber soft mode
500-600 service life.
Above example is simply to illustrate that the present invention, some cited more preferably embodiments, this area skill
The usual variations and alternatives that art personnel are carried out in the range of the technical program should include within the scope of the present invention.
