Description
Technical field
The present invention relates to a kind of thiofide N, the granulation of N- dicyclohexyls -2-[4-morpholinodithio sulfenamide (DZ)
Agent and process for producing same is bonded, belongs to rubber vulcanization accelerator DZ production technical field.
Background technology
DZ is delayed action accelerator, is a kind of essential primary accelerator of current rubber industry.Especially suitable for son
Radial tire, there is vulcanization promotion and adhesive effect.Crystal formation of DZ materials itself is big, and DZ grains are broken in circular flow, efflorescence
Rate is high, influences client and uses and cause environmental pollution.Automatic packaging can solve caused dust in production but DZ grains in itself
Easily broken, lower hardness, average hardness is less than 2, and pulverization rate, can by pulverization rate after packing automatically between 5% to 10%
Rise to 10% to 20%.The accuracy that DZ products are fed intake in client using middle automatic weighing can be directly affected, influences product matter
Amount.Substantial amounts of dust causes environmental pollution during feeding intake.It is to make to reduce one of method of DZ product pulverization rates at this stage
Grain process work material process adds the adhesive of outsourcing, and the main component of adhesive is cellulose, polyvinyl alcohol, white oil and emulsification
Agent is during DZ is granulated material process addition mixing of living, if the addition control of adhesive exception occurs and can directly affect DZ
Product quality, if serious situation can influence DZ products, the very risky of effect during client's use can produce in DZ
During find a kind of waste material difficult with pre-treatment, by simply processing, do not increasing the situation of large number quipments and cost
A kind of lower new Granulating Bonding Agent of synthesis, substitutes original outsourcing adhesive, not only can be with cost-effective, improvement product quality
Waste material is reduced simultaneously produces the requirement for meeting country's safety and environmental protection production at this stage and green production
The content of the invention
The purpose of the production method of rubber vulcanization accelerator DZ Granulating Bonding Agent of the present invention is that provide one kind is produced with DZ
During filter brine reservoir caused by material be raw material, being quantitatively adding ethanol solution in brine reservoir is stirred dissolving, together
When control solution temperature, after being prepared into solution, this solution is transplanted in granulating working procedure adhesive storage tank with pump, it is viscous as being granulated
Mixture uses, and substitutes original outsourcing adhesive.To lift DZ grains average hardness and reduce pulverization rate.Recycle simultaneously in the past
Caused solid waste in DZ productions, lift yield and reduce environmental pollution.And realize the automatic packaging that DZ is granulated.
Technical scheme is as follows：
A kind of production method of rubber vulcanization accelerator DZ Granulating Bonding Agent, step are as follows：
1) ethanol solution and DZ brine reservoir waste materials are added in DZ brine reservoirs, it is 1 to prepare mass-volume concentration
~2Kg/L solution；Stir to form homogeneous solution at 40 DEG C~50 DEG C；For Granulating Bonding Agent；
2) it is being granulated 1% ratio addition Granulating Bonding Agent of the material process living according to DZ weight of material.
The advantage of the invention is that：To filter material caused by brine reservoir in DZ production processes as raw material, stored up in salt solution
Tank is quantitatively adding ethanol solution and is stirred dissolving, while controls solution temperature, and after being prepared into solution, this solution is transferred with pump
Into granulating working procedure adhesive storage tank, used as Granulating Bonding Agent, adhesive derives from DZ production process in itself, substitutes former
There is outsourcing adhesive.To lift DZ grains average hardness and reduce pulverization rate.Recycle simultaneously caused by conventional DZ productions
Solid waste, lift yield and reduce environmental pollution.The high quality problems of finished product grain pulverization rate.Realize the automatic packaging that DZ is granulated.It is logical
Crossing addition adhesive makes the pulverization rate of DZ grains reach 2%~3%, and average hardness reaches 2.5~3.5.Greatly improve product matter
Amount, the pulverization rate of DZ grains is reduced, realize the automatic packaging of DZ grains.And recovery uses waste material, reduces environmental pollution.Single batch of yield
Rise 3 to 5 kilograms.
