Abstract: The catalytic oxidation experiments were carried out to prepare the horniness oxidized wax from paraffin wax and polyethylene. The results show that good products can be obtained under the following conditions: reaction temperature 170 ℃, reaction time 7 h, mass ratio of paraffin wax and polyethylene 7∶3, the amount of catalyst 0.01%, the amount of additive 1.0%, the air flow 0.20 m3/h. acid number of the product was 9.82 mg(KOH)/g, saponification number is 79.19 mg(KOH)/g, penetration is 9.2 (0.1 mm), melting point was 87.4 ℃, index of refraction(75 ℃ ) was 1.453 6. As compared with natural hard wax(carnauba wax),their properties were quite similar each other.

Key words: Wax, Oxidation, Hardness, Penetration
