Described auxiliary agent is made by the raw material of following weight part: diatomite 40-45, vinylformic acid dimethylamino ethyl ester 2-3, ethoxylated trimethylolpropane triacrylate 3-4, jade 1-2, nano titanium oxide 3-4, Union carbide A-162 1-2, linking agent TAC1-2, aluminium hydroxide 8-10, oxidation inhibitor 1035 1-2; Preparation method puts into diatomite, jade mixing calcining furnace and calcine 3-4 hour at 700-720 ℃, 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 material for the manufacture of water tumbler housing of the present invention, by following concrete steps, made:
(1) will gather-4-methyl-1-pentene is heated to molten state, add long glass fibres, Calucium Silicate powder, acrylic ester impact-resisting modifier ACR, tributyl citrate, anti-aging agent RD, 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: modified polycarbonate material of the present invention has good machinery and mechanical system performance, intensity is high, coefficient of elasticity is high, there is higher shock resistance, there is good dimensional stability and good moulding processability, the harmless hygienic safety that meets of tasteless odorless.
