Technical field
The present invention relates to plastics field, particularly temp. variation resistant polycarbonate material and preparation method thereof for a kind of water tumbler housing.
Background technology
Polycarbonate (being called for short PC) is the high molecular polymer that contains carbonate group in molecular chain, due to the singularity on polycarbonate structure, has now become the fastest general engineering plastic of rate of growth in five large-engineering plastics.Due to polycarbonate article, to have quality light, and shock resistance and the transparency are good, and indeformable and keep transparent advantage during by hot water and caustic soln carrying out washing treatment, some field PC bottles replace vial completely.It is predicted, along with people are to the improving constantly of drinking water quality attention degree, polycarbonate consumption rate of growth in this respect will remain on more than 10%, and the water tumbler housing of therefore researching and developing a kind of polycarbonate material is trend of the times.
Summary of the invention
The object of this invention is to provide temp. variation resistant polycarbonate material and preparation method thereof for a kind of water tumbler housing.
In order to realize object of the present invention, the present invention passes through following scheme implementation:
A housing temp. variation resistant polycarbonate material, is made by the raw material of following weight part: polycarbonate 500-520, tetrafluoroethylene 30-35, terephthaldehyde's acetoacetic ester 10-12, silicon carbide 10-13, dibutyl tin laurate 1-2, Diethylene Glycol Dibenzoate 4-5, auxiliary agent 10-12;
Described auxiliary agent is made by the raw material of following weight part: diatomite 40-45, tri (propylene glycol) diacrylate 3-4, double pentaerythritol methacrylate 2-3, tripoly phosphate sodium STPP 5-6, jade 4-5,
silane resin acceptor kh-550 1-2,linking agent TAC1-2, silicon carbide 4-5, polyisobutene 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.
Water tumbler housing temp. variation resistant polycarbonate material of the present invention, by following concrete steps, made:
(1) tetrafluoroethylene is heated to molten state, adds terephthaldehyde's acetoacetic ester 10-12, silicon carbide 10-13, dibutyl tin laurate, auxiliary agent, stir and mediate 15-25 minute, send into twin screw extruder granulation, obtain A material;
(2) dried polycarbonate is heated to 240-280 ℃, 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: polycarbonate material of the present invention has good temperature-change resistance and ageing resistance, weathering resistance, mechanical property is good, intensity is high, impact strength is high, use temperature scope is wide, safety non-toxic, the harmless hygienic safety that meets of tasteless odorless, is applicable to making water tumbler housing.
