Described auxiliary agent is made by the raw material of following weight part: diatomite 40-45, vinylformic acid dimethylamino ethyl ester 4-5, tri (propylene glycol) diacrylate 2-3, zinc oxide 5-6, jade 4-5,3-aminopropyl trimethoxysilane 2-3, linking agent TAC1-2, Zinc Gluconate 1-2, Zinic stearas 1-2, Flos Rosae Rugosae quintessence oil 0.1-0.2; Preparation method puts into diatomite, jade mixing calcining furnace and calcine 3-4 hour at 710-740 ℃, cooling, put into 10-12% hydrochloric acid soln and soak 1-2 hour, filter and take out, with clear water, clean and dry, be ground into 200-400 order powder, mix with other remaining component, grinding distribution is even, obtains.

Modified polycarbonate water tumbler case material of the present invention, by following concrete steps, made:

(1) will gather-4-methylpentene-1 is heated to molten state, adds octaphenylcyclotetrasiloxane, vinyl trialkyl oxysilane, phenyl-phosphite, morpholine, zinc oxide, auxiliary agent, stirs and mediates 15-25 minute, sends into twin screw extruder granulation, obtains A material;

(2) dried polycarbonate is heated to 245-280 ℃, adds other remaining component, stir 7-10 minute, send on twin screw extruder and melt extrude granulation, obtain B material;

(3) after A, B material is mixed, on twin screw extruder, melt extrude granulation, obtain.

The present invention has the following advantages: modified polycarbonate material of the present invention, changed the inadequate shortcoming of polycarbonate material wear resistance, there is good wear resistance, and there is high strength, high impact, use temperature scope is wide, good processability, shaping shrinkage rate is low, dimensional stability is good, the harmless hygienic safety that meets of tasteless odorless.
