POLYMER PROPPANT MATERIAL AND METHOD FOR PRODUCING SAME |
摘要 |
A polymer material for proppant in the form of a metathesis-radically cross-linked mixture of oligocyclopentadienes and methylcarboxy norbornene esters is obtained by mixing dicyclopentadiene with methacrylic esters and polymer stabilizers, heating the mixture to a temperature of 150-220° C., holding at said temperature for 15-360 minutes, and then cooling down to 20-50° C. A radical initiator and a catalyst are added successively to the resultant mixture of oligocyclopentadienes and methylcarboxy norbornene esters. The polymer matrix is heated to a temperature of 50-340° C., is held at this temperature for 1-360 minutes and then is cooled to room temperature. A technical result achieved by implementation of the present invention is an increase in thermal strength of the proppant material, providing a compressive strength of at least 150 MPa at a temperature of not less than 100° C. |
