Abstract
The invention discloses a kind of preparation technology of wear resistant corrosion resistant high-strength die material,By nano-hollow molybdenum disulfide,Process hides chromium-bearing sludge,Carborundum,Nano Mo powder,Nano barium phthalate,Neodymia,Particle reinforcements,Sodium sulphate,Titanium chloride,Sodium hypophosphite,Sodium borohydride,Sodium citrate,Ammonium sulfate,Sodium hydroxide,Lactic acid and catalyst by proportion are well mixed,It is added in body of heater,In fusion process,Vacuum is evacuated to less than after 8.0 × 10 3Mpa using non-consumable arc furnace body of heater,It is filled with high purity argon,Start striking melting,Electric current is slowly increased to 250 ~ 300A,And keep electric current stable,Alloy cast ingot is overturn after melting 10min,Melting again,Each alloy full pattern melt back 3 times,To ensure that alloy melting is uniform,Produce high-strength die material,Resulting materials have excellent mechanical performances,Abrasion resistance and decay resistance.
Description
Technical field
The present invention relates to mold materials preparation technology field, and in particular to a kind of preparation technology of mold materials.
Background technology
In process of industrialization, basis of the mold manufacturing industry as the national economic development, by the height of government and enterprise
Concern.In the industrial production, the precision of mould how is improved, shortens the mold design cycle, extends die life, is to need badly
The technical barrier of solution.Mold materials not enough improve in the prevalence of mechanical property at present and what wearability was unsatisfactory lacks
Fall into, while in order to improve its service life, it is necessary to add the metal of anticorrosive property, thereby increase cost.
On the other hand, China is process hides big country, the annual substantial amounts of chromium-bearing sludge of output, and chromium sludge can not fill, it is impossible to
Burn privately, cause 1500 ~ 3000 yuan of processing costs not waited of every sludge needs at present, drastically influence the life of leather-making enterprises
The problem of depositing and developing.
The content of the invention
The technical problem to be solved by the invention is to provide a kind of preparation work of wear resistant corrosion resistant high-strength die material
Skill, the service life of the mold materials of preparation at high temperature is longer, and has excellent physical property, effectively to solve background
The problem of in technology.
In order to solve the above-mentioned technical problem, present invention employs following technical scheme：
A kind of preparation technology of wear resistant corrosion resistant high-strength die material, it is characterised in that formula as below component is well mixed,
It is added to melting in body of heater and obtains wear resistant corrosion resistant high-strength die material：Nano-hollow molybdenum disulfide 58-70 parts, process hides contain chromium
Sludge 25-30 parts, carborundum 3-5 parts, nano Mo powder 6-8 parts, nano barium phthalate 4-6 parts, rare earth oxide 2-4 parts, particle increase
Strong agent 1-2 parts, sodium sulphate 1-3 parts, titanium chloride 2-3 parts, sodium hypophosphite 8-10 parts, sodium borohydride 15-20 parts, sodium citrate 10-
15 parts, lactic acid 10-14 parts, ammonium sulfate 8-12 parts, sodium hydroxide 8-13 parts and catalyst 5-7 parts；
Its middle rare earth is any one in neodymia, praseodymium oxide and cerium oxide；
The wherein preparation method of particle reinforcements：Ethylenediamine tetra-acetic acid 4-6 parts, sodium carboxymethylcellulose 3-4 are added into container
Part, pentaerythrite 5-7 parts and diethylphosphoryl guanidine-acetic acid 40-60 parts, water 400-600 parts and aluminium hydroxide 8-12 are added afterwards
Part, be heated to 88-92 DEG C so that resulting solution flow back, keep 88-92 DEG C at 1.5-2.5h, using Rotary Evaporators remove water with
Remain solid matter, add 180-220 part ethanol, and cross isolated by vacuum filtration solid, be seated in vacuum drying oven dry every
Night；
The wherein preparation method of catalyst：It is accurate respectively to claim CdLa2S41-2 parts, carborundum 0.4-0.8 parts, nano titanium oxide
0.2-0.4 parts, BTCA 0.5-1 parts and the mixing of PCDL 2-4 parts, it is placed in agate mortar grinding 15-30
