The technical solution adopted by the present invention：Phenolic resin cutting sheet and the preparation technology of grinding, it is prepared by following steps
Form：
1. prepared by raw material：Moistening bonding agent is added in the black corundum after magnetic separation, and in the upper of the double pot adverse current batch mixers of 120L
Pot is well mixed；Inserts, auxiliary material bonding agent are uniformly mixed in three-dimensional mixer in addition, and by mixed mixing
Material pours into cooking for the double pot adverse current batch mixers of 120L, and pot and interior compound of cooking are mixed on double pots of adverse current batch mixers, and
Place 10-14 hours at low temperature；
2. it is molded：Well-mixed material delivers to assembly room after screening in upper step, in assembly room to material through people
Work sends into forming machine after weighing automatically, and the idiosome through extruding compressing is divided into cutting sheet and grinding, and pad puts one between grinding
Piece aluminium sheet, pad puts a filter between section, and cutting sheet and grinding must be in placed on top spring compressions after putting neatly；
3. harden：By the cutting sheet being well placed and grinding feeding tunnel cave, hardened under 160-200 degrees Celsius, curing cycles 24
Hour, cutting sheet and grinding after hardening are phenolic resin cutting sheet and grinding, then packaged is finished product.
Further, described moistening bonding agent is liquid phenolic resin.
Further, described inserts is the one or more in potassium fluoroaluminate, cryolite or iron sulfide.
Further, described auxiliary material bonding agent is that nanometer/TiO2 modified boron containing phenolic resin composite materials are bonding agent.
Further, the cutting sheet and grinding add colouring agent before the forming.
Its advantage is the present invention compared with prior art：The energy such as the inserts and auxiliary material bonding agent that are used in the present invention
It is sufficiently mixed with black corundum, occurs qualitative change；The present invention passes through multiple formula test, optimization filler kind and proportioning and manufacture work
Skill, the new formula of bonding agent, filler is developed according to the physicochemical property board design of black corundum, then is equipped with new nanometer and is changed
Property boron bakelite resin mixing, selective enhancement screen cloth is compressing, controls elevated cure, and high-performance cutting sheet is made and grinding is produced
Product；The present invention uses raw material and nanometer/TiO2 modified boron containing phenolic resin composite materials based on black corundum as bonding agent, with reference to
Intensity is good, and security performance is high, with good toughness and heat resistance, is widely used in snagging, corase grind, thermal cutting and cold cut and cuts
（Grinding）, half fine grinding, fine grinding, the process such as polishing.
Embodiment
A kind of phenolic resin cutting sheet and the preparation technology of grinding, it is prepared from by following steps：
1. the present invention is used using finished product black corundum as the raw material of black corundum phenolic resin cutting sheet and grinding production, prepares phenol
When urea formaldehyde cutting sheet and grinding, liquid phenolic resin need to be added in the black corundum raw material after magnetic separation, and in the double pots of 120L
The upper pot of adverse current batch mixer is well mixed；Inserts and auxiliary material bonding agent are uniformly mixed in three-dimensional mixer in addition,
And mixed compound is poured into cooking for the double pot adverse current batch mixers of 120L, pot and interior mix of cooking on double pots of adverse current batch mixers
Close material to be mixed, and place more than 12 hours at low temperature；Described inserts is the auxiliary material for playing cooling effect, is made simultaneously
The auxiliary material such as inserts, bonding agent energy and black corundum are sufficiently mixed, and occur qualitative change.Described inserts is potassium fluoroaluminate, fluoaluminic acid
One kind in sodium or iron sulfide.
The mixer of this process can produce relatively low noise pollution.This project is by multiple formula test, optimization filling
Agent kind and proportioning and manufacturing process.Bonding agent, the new of filler are developed according to the physicochemical property board design of black corundum to match somebody with somebody
Side, then new nano modification boron bakelite resin mixing is equipped with, selective enhancement screen cloth is compressing, controls elevated cure, is made
High-performance cutting sheet and grinding product.
2. well-mixed material is after screening by manually delivering to cutting sheet and grinding assembly room, assembly room arrangement
