| Abstract: | The process method of kaolin was introduced using A-151 and ester titanate coupling agent. Effect of dosage of A-151 and ester titanate coupling agent on stretch strength and modulus, bending strength and modulus , impact strength of UPR was investigated. Experiment showed that stretch strength, bending strength and impact strength of UPR were increased which was filled by treated kaolin. At A-151 1%, ester titanate 0.8,filled amount of coupling kaolin 30%, stretch strength, bending modulus and impact strength of UPR were increased from 44.38 MPa,72.66 MPa,9.68 KJ/m 2 to 56.34 MPa,98.31 MPa,13.25 kJ/m 2 and 49.96 MPa,89.65 MPa,14.56 kJ/m 2.Coupling kaolin had obvious effectiveness for filling UPR. |
