Abstract
The invention discloses a modified polycarbonate material for water cup shells. The modified polycarbonate material is characterized by being prepared from the following raw materials in parts by weight: 500-520 parts of polycarbonate, 20-24 parts of PE (Polyethylene), 16-19 parts of polystyrene, 4-8 parts of diatomite powder, 4-5 parts of aluminum hydroxide, 4-5 parts of molybdenum sulfide, 1-2 parts of graphite, 9-10 parts of parachlormetaxylenol, 12-15 parts of propyl methacrylate and 10-12 parts of additive. The modified polycarbonate material has relatively good wear resisting property, anti-cracking property, high strength and elastic coefficient, high impact strength, wide using temperature range and high surface smoothness, is simple in production technology, low in formation shrinking percentage, good in size stability, tasteless, odorless and harmless to human bodies and conforms to the sanitary safety.
Description
Technical field
The present invention relates to plastics field, particularly modified 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 modified 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 modified polycarbonate material, is made by the raw material of following weight part: polycarbonate 500-520, PE20-24, polystyrene 16-19, diatomite in powder 4-8, aluminium hydroxide 4-5, moly-sulfide 4-5, graphite 1-2, parachlormetaxylenol 9-10, propyl methacrylate 12-15, 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.
Described water tumbler housing modified polycarbonate material, by following concrete steps, made:
(1) polystyrene is heated to molten state, adds aluminium hydroxide, moly-sulfide, graphite, parachlormetaxylenol, auxiliary agent, stir and mediate 15-25 minute, send into twin screw extruder granulation, obtain A material;
(2) dried polycarbonate is heated to 245-285 ℃, adds other remaining component, stir 6-10 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, there is good wear resisting property and anti-cracking performance, production technique is simple, shaping shrinkage rate is low, dimensional stability is good, high strength and coefficient of elasticity, high impact, use temperature scope are wide, surface smoothness is high, the harmless hygienic safety that meets of tasteless odorless.
