The invention discloses a preparation method for an
oil absorption material made of
polypropylene non-woven cloth. The preparation method comprises the steps of treatment of the
polypropylene non-woven cloth, preliminary
grafting reaction,
grafting reaction and final treatment so as to obtain the
oil absorption material made of the
polypropylene non-woven cloth. In the preliminary
grafting reaction and the grafting reaction, a
monomer drop addition method or a
monomer infusion method is adopted. The process of the drop addition method is as follows: adding an oleophylic
monomer dropwise in preliminary grafting reaction solution, and conducting the grafting reaction for 30 minutes to 120 minutes under constant-temperature agitation so as to obtain a graft
polymerization product, wherein the oleophylic monomer belongs to
methacrylic acid alkyl esters, and the adding amount of the oleophylic monomer is 3%-6% of the total
mass of the preliminary grafting reaction solution. The process of the
infusion method is as follows: taking out a product of the grafting reaction, putting the product into the oleophylic monomer, conducting constant-temperature agitation, and conducting the grafting reaction for 30 minutes to 120 minutes so as to obtain the graft
polymerization product, wherein the oleophylic monomer belongs to
methacrylic acid alkyl esters, and the adding amount of the oleophylic monomer is 3%-6% of the total
mass of the preliminary grafting reaction solution.
