Embodiment 1
[0024] A pour point and drag reducing agent, composed of the following components in parts by weight:
[0025] 147-150 parts of 1-butene;
[0026] 180-185 parts of vinyl acetate;
[0027] Titanium tetrachloride-triethylaluminum 0.5-1 part;
[0028] 570-575 parts of n-butanol;
[0029] Emulsifier OP-10 90-100 parts.
[0030] A preparation method of the pour point and drag reducing agent is carried out according to the following steps:
[0031] Step 1, purging the stainless steel reaction vessel with nitrogen, then sequentially adding 147-150 parts of 1-butene, 180-185 parts of vinyl acetate and 0.5-1 part of titanium tetrachloride-triethyl Aluminum-based catalyst, sealed and placed in a 0°C low-temperature reaction container to react at 0°C for 3 to 6 days;
[0032] Step 2: Grind the product after the reaction in step 1 into powder in an environment below -30°C, and add 570-575 parts of n-butanol and 90-100 parts of emulsifier OP-10 to the powder to prepare The product th...
Embodiment 2
[0037] The pour point and drag reducing agent provided in this example is prepared according to the amount of the following raw material components:
[0038] Step 1, purging the stainless steel reaction vessel with nitrogen, then adding 147 parts of 1-butene, 185 parts of vinyl acetate and 1 part of titanium tetrachloride-triethylaluminum catalyst in this reaction vessel successively, after sealing Put it into a low-temperature reaction container at 0°C, and let it react at 0°C for 6 days;
[0039] Step 2: Grind the product after the reaction in step 1 into a powder in an environment of -30°C, and add 575 parts of n-butanol and 100 parts of emulsifier OP-10 to the powder to make a white suspension The product is pour point depressant and drag reducer.
Embodiment 3
[0041] The pour point and drag reducing agent provided in this example is prepared according to the amount of the following raw material components:
[0042] Step 1, purging the stainless steel reaction vessel with nitrogen, then adding 150 parts of 1-butene, 180 parts of vinyl acetate and 0.5 part of titanium tetrachloride-triethylaluminum catalyst to the reaction vessel successively, after sealing Put it into a low-temperature reaction container at 0°C, and let it react at 0°C for 3 days;
[0043] Step 2: Grind the product after the reaction in step 1 into a powder in an environment of -35°C, and add 570 parts of n-butanol and 90 parts of emulsifier OP-10 to the powder to make a white suspension The product is pour point depressant and drag reducer.
