3) phosphoric acid degumming: the crude fish oil of precise certain mass is in beaker, be placed on heated and stirred to 80 DEG C in water-bath, slowly adding crude fish oil amount 1% concentration is the phosphoric acid of 75%, continuous stirring is until evenly, 6 min are heated under condition at 80 DEG C, then with the centrifugal 15min of 3500rpm, isolate upper strata oil sample, be the crude fish oil that comes unstuck; This step is carried out under being in inflated with nitrogen state always;
4) sodium hydroxide depickling: add the NaOH dissolution homogeneity stirring of 12 ° of Be of 0.2% in the fish oil that comes unstuck after, be heated to 65 DEG C, insulation 30min, is then cooled to room temperature, static layering, with the centrifugal 15min of 4000rpm, removing precipitation.
5. and then remove the soap that remains with the washing of certain volume, until clean up; Upper strata depickling crude fish oil is got after separatory; This step is carried out under being in inflated with nitrogen state always;
5) crude fish oil decolouring: the depickling fish oil of above-mentioned gained is heated to 65 DEG C in a water bath, adds 12% atlapulgite, constantly stirs and makes to mix, and after maintaining 20min, with the centrifugal 15min of 4000rpm, is separated and obtains the fish oil that decolours;
6) fish oil takes off raw meat: step 5) gained decolouring fish oil is put into round-bottomed flask, utilizes Rotary Evaporators to be heated to 70 ~ 80 DEG C of deodorization 30 ~ 40min; Except smelling removal stink substance, obtain deep sea fish oil.
6. heavy crude thinner according to claim 4 and preparation method thereof, is characterized in that: described antioxidant is selected from natural VE or S-WAT or Sodium Pyrosulfite or 2,6 di tert butyl 4 methyl phenol or its combination; Described step 3) to step 6) is carried out under being in inflated with nitrogen state.
7. heavy crude thinner according to claim 1-4 and preparation method thereof, is characterized in that: described highly basic is selected from potassium hydroxide or sodium hydroxide.
8. heavy crude thinner according to claim 1-5 and preparation method thereof, is characterized in that: described oil-soluble viscosity reducer is selected from No. 120 solvent oils.
9. heavy crude thinner according to claim 1-5 and preparation method thereof, is characterized in that: described nonionogenic tenside is selected from 6501 or APG or its and combines.
10. heavy crude thinner according to claim 1-5 and preparation method thereof, is characterized in that: OP-10 selected by described emulsifying agent.
11. heavy crude thinners according to claim 1-5 and preparation method thereof, is characterized in that: iso-pentane selected by described isomery alcohol.
