Processing, inorganic agent is nanometer is siliceous and carbonaceous particle.
A kind of production technology of interface modification type high-strength environment-friendly heavy duty grinding wheel, by calcareous or magnesia compound and activity
The charcoal particle and abrasive material of modification, auxiliary material and resin-oatmeal are blended.
A kind of production technology of interface modification type high-strength environment-friendly heavy duty grinding wheel, which is characterized in that step is as follows：
（1）Abrasive material and auxiliary material are subjected to nano modification processing, inorganic agent is nanometer is siliceous and carbonaceous particle；
（2）Resin-oatmeal and abrasive material auxiliary material are blended 15 minutes at a high speed, resin-oatmeal is made adequately to be wrapped in abrasive surface, auxiliary material is uniform
Be dispersed between resin and abrasive material；
（3）Calcareous or magnesia compound and active carbon particle are poured into and are blended with other powders；
（4）Mixed final powder is poured into high-strength die, by the pressure of 50-80Mpa, 180-200 DEG C of temperature into
Row hot pressed sintering, sintering time are 30-40 minutes；
（5）Cryogenic gas or liquid will be sprayed after the product stripping sintered, refine product grains；
（6）Grinding wheel stands 24-36 hours after cooling；
（7）Grinding wheel, which is put into baking oven, after standing carries out secondary curing, and solidification temperature is 180-200 DEG C, and the time is 5-7 hours；
（8）It is finished after curing, balance test；
（9）Product passes through packaging and storage after 2.05 times of rotary safeties (domestic standard is 1.5 times, and international standard is 2.05 times).
Further, the abrasive material is one or more of fused alumina zirconia, Brown Alundum, single alundum.

The compound of water or water.
The present invention carries out surface modification using the principle of interface cohesion to abrasive material and auxiliary material, in enhancing abrasive material, auxiliary material and tree
It is absorbed while cosmetics interface bond strength and decomposes gas and moisture that resin generates in the curing process.
The technique mainly has three dot characteristics：
1st, high interfacial bonding strength.Nanometer aluminium silicate, nanometer silicon carbide, which are used together, makes abrasive material and resin more secured in combination
While improve combination interface heat resistance and inoxidizability.Abrasive material is made to be greatly improved with resin bonding strength using the principle,
The tension and impact strength of product can obtain the promotion of 7-12%.
2nd, zero exhaust gas discharges, 0.3% ultralow-porosity.Three kinds of calcareous compound, magnesia compound, active carbon particle materials
Material uses adsorbable thermoplastic resin（Such as phenolic aldehyde）The ammonia and moisture discharged in the curing process, predominantly chemical reaction are inhaled
It is attached, it is on a small quantity physical absorption.The exhaust gas discharge in production process can be effectively reduced in this way, while reduces the porosity of grinding wheel,
Improve wheel strength and abrasion resistance.This technique is than the high 12-23% of grinding performance of conventional heavy duty grinding wheel（Product gas porosity exists
Less than 7% heavy duty grinding wheel, 3-4% can be promoted by often reducing by 1% porosity product grinding performance）.
3rd, high intensity, odorlessness, ultralow stomata, the protrusion of high grinding performance of the invention for realizing heavy duty grinding wheel is excellent
Gesture makes product catch up with and surpass Japan and the U.S., reaches the international leading level.
