Record one
S1: Take tristearin, stir while feeding, keep the temperature level at 100 ° C, include energizer A, antioxidant as well as water after the tristearin is completely thawed, at a temperature of 135 ° C and additionally a stress and anxiety of 0.7 MPa Accomplish hydrolysis feedback under the trouble of problem, hydrolyzate delays 45min, oil and water are separated, and likewise oil stage stress filtration redeems stimulant as well as additionally rapidly gets stearic acid;
Wherein, in regards to mass proportion, in chauffeur A, zinc oxide: Al2O3-MgO is 1: 6, as well as also its intake is 4% of the high quality of glyceryl tristearate, as well as also Al2O3-MgO is prepared by rainfall method, in addition to in molar proportion, Al2O3: MgO is 2.5:1;
In regards to mass percentage, in anti-oxidants, antioxidant 1076: antioxidant DLTDP: antioxidant T501 is 0.12: 0.38: 1, and its intake is 0.5% of tristearin top quality;
By mass proportion, glyceryl tristearate: water is 1: 0.45;
S2: Include the stearic acid in S1 right into the zinc stearate feedback pot, maintain the temperature level at 110 ° C, include zinc oxide with 9% mass of tristearin while blending, after feeding, the temperature level of the material rises to 120 ° C, include driver B with 3% glyceryl tristearate mass, as well as additionally stir for thirty minutes;
Wherein, energizer B is the blend of hydrogen peroxide and zinc peroxide, by mass percentage, hydrogen peroxide: zinc peroxide is 4: 1;
S3: Include zinc oxide with 3.8% tristearin mass and also energizer B with 2% tristearin mass, respond at a temperature of 130 ° C, stop mixing, as well as the foam of the product goes down to the balance factor, include chauffeur B with 0.5% tristearin mass, and react at a temperature level of 150 ° C. for 20 mins;
S4: Include salt hydroxide of 0.25% by mass of glyceryl tristearate while mixing, and respond at regular temperature level for half an hour;
S5: Turn on the air pump, readjust the vacuum degree to -0.08 MPa, dry out, as well as respond stably for 60 mins under consistent temperature level as well as likewise regular stress conditions, the response is terminated, sampling and also testing, spraying powder after passing the examination, packaging and additionally storage space, to obtain zinc stearate, the return is 94.87%.
Record two,
A prep work method of mass zinc stearate, a, under regular stress, 1400g stearic acid is dropped into an activator as well as heated to 130-160 ° C. After including stimulant hydrogen peroxide 70g and also zinc oxide 220g, the response is liquified state for 90 mins; B, add antioxidant 5g and mix for 5-20 minutes; c, add in the mold and mildew that is positioned the polyethylene mesh skeletal system in the liquified zinc stearate that step b makes; D, make the needed shape after cooling Zinc stearate in swellings.
Report three
A kind of manufacturing approach of zinc stearate, described zinc stearate is prepared by the response of each element of complying with components by weight: 800-1200 parts of stearic acid, 140-170 parts of zinc oxide, 5-15 parts of stimulant, 50-70 parts of deionized water;
The manufacturing approach of zinc stearate, consists of the adhering to steps:
( 1) Place 800-1200 parts of stearic acid and also 140-170 parts of zinc oxide into the reactor, heat up to 57-65 ° C, begin mixing, after mixing for 8-15 minutes, add 5-15 parts of stimulant and also 50-70 parts of deionized water, cover the cover of the reaction pot, and also remain to heat up for the reaction;
( 2) Beginning the reaction when the temperature level in the reactor rises to 75-80 ° C, stop heating when the temperature remains to rise to 93-98 ° C, maintain the temperature secure, react for 18-25min until the pressure in the activator rises to 2-2.5 kg f/ cm2, open the exhaust valve of the activator to exhaust;
( 3) After the exhaust is finished, open up the cover of the kettle. At this time, the response product changes from liquid to powdery solid, and also the response is completed;
( 4) Release the reacted product from the response kettle, and also obtain the item with the crushing process.
Drivers consist of acetic acid, hydrogen peroxide, potassium hydroxide solution, and also ammonia.
