A kind of sand paper additive utilizing petroleum coke to prepare
Technical field:
The present invention relates to petrochemicals technical field, be specifically related to a kind of sand utilizing petroleum coke to prepare
Paper additive.
Background technology:
Sand paper, is commonly called as rubber, is a kind of for abradant material, in order to the surface such as abrasive metal, timber,
So that it is bright and clean smooth.According to different abrasive materials, sand paper be divided into emery paper, artificial diamond's sand paper,
Glass papers etc. are multiple.Dry abrasive paper is used for polishing wood, articles made of bamboo surface, water-proof abrasive paper in water or
Burnished metal or non-metal workpiece surface in oil.
Petroleum coke is crude oil after light mink cell focus is separated by distillation, and mink cell focus, again through the process of hot tearing, converts
Product.From the appearance, coke be black in irregular shape, not of uniform size block (or
Grain), there is metallic luster, the particle tool multi-pore structure of coke, main element consists of carbon, occupies
More than 80wt%, remaining is hydrogen, oxygen, nitrogen, sulphur and metallic element.At present, commercially available sand paper exists fragile
The problem of damage, grinding effect difference, and the sand paper additive utilizing petroleum coke to prepare has no report.The present invention
Made sand paper additive can significantly improve the grinding effect of sand paper, extends the use time of sand paper.
Summary of the invention:
The technical problem to be solved is to provide one be favorably improved grinding effect and extend sand
Paper uses the sand paper additive utilizing petroleum coke to prepare of time.
The technical problem to be solved uses following technical scheme to realize:
A kind of sand paper additive utilizing petroleum coke to prepare, is made up of the raw material of following parts by weight:
Petroleum coke 25-30 part, castor oil 15-20 part, attapulgite 10-15 part, Brazil wax
10-15 part, carbomer 7-12 part, polyvinyl alcohol 6-10 part, hydrogenated rosin 6-10 part, sepiolite powder 5-8
Part, butadiene rubber 4-6 part, asbestos wool 3-5 part, lanolin 3-5 part, octadecyl alcolol 1-2 part, three oxidations
Two antimony 0.5-1 parts, rare earth 0.1-0.2 part;
Its preparation method comprises the steps:
(1) hydrogenated rosin is dissolved in castor oil, adds Brazil wax and lanolin, be heated to
85-90 DEG C of insulation mixing 10min, then proceedes to be heated to 115-120 DEG C of insulation mixing 10min, obtains thing
Material I;
(2) utilize graded impact mill that petroleum coke is made powder, add recessed after being heated to 100-110 DEG C
Convex rod soil, sepiolite powder and asbestos wool, mix, obtain material II;
(3) after butadiene rubber and polyvinyl alcohol being sufficiently mixed grind 30min, add material I, material II,
Carbomer, octadecyl alcolol, antimony oxide and rare earth, be sufficiently mixed uniformly.
Described attapulgite passes through pretreatment before using, and its processing method is: first by 60-70 part attapulgite
Add in 120-150 part ethanol with 10-15 part mass fraction 20% sodium-chloride water solution, after being heated to 50-60 DEG C
30min is ground in insulation, adds 8-11 part polyacrylamide and 4-6 part ethoxylated dodecyl alcohol, fully
Prior to microwave treatment 15min under microwave frequency 2450MHz, power 800W after mixing, then at supersonic frequency
Ultrasonically treated 15min under 40kHz, power 50W, is subsequently adding 2-4 part nano-ceramic powder and 3-5 part nanometer
Rubber powder, continues ultrasonically treated 10min, the most vacuum dried after make powder.
The invention has the beneficial effects as follows: the present invention, with petroleum coke as primary raw material, is aided with castor oil, recessed
Native and the multiple auxiliary agent of convex rod prepares sand paper additive, and the use of this additive can not only be effectively improved sand paper
Internal flexibility, it is to avoid what common sand paper existed causes foldable and disrepair phenomenon because inside is really up to the mark;And
And the grinding effect of sand paper can be effectively improved, extend the use time of sand paper, reduce replacement cost.
