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.

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

(1) isotatic polypropylene is heated to molten state, adds tributyl citrate, titanium dioxide, nano-calcium carbonate, polyacrylamide, epoxy soybean oil, auxiliary agent, stir and mediate 15-25 minute, send into twin screw extruder granulation, obtain 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: the present invention has fabulous toughness, and intensity is high, and coefficient of elasticity is large, and shock strength is large, and use temperature scope is wide, and technique is simple, and cost is low, and the tasteless odorless of water tumbler case material of production, to human-body safety, is worthy to be popularized.
