Abstract
The invention discloses a styrene-ethylene/butylene-styrene block copolymer (SEBS) modified polycarbonate composite material for a cup body. The SEBS modified polycarbonate composite material is characterized by being prepared by the following raw materials in parts by weight: 500-520 parts of polycarbonate, 19-22 parts of SEBS, 2-3 parts of hexamethylphosphoric triamide, 12-14 parts of attapulgite powder, 4-5 parts of zinc stearate, 20-30 parts of hydroxyethyl methacrylate phosphate, 2-3 parts of simethicone, 3-4 parts of zinc oxide, and 10-12 parts of addition agent. The modified polycarbonate composite material not only has good processability, cracking resistance and mechanical property, but also has stable quality, is safe and environment-friendly, is odourless and harmless to human bodies, accords with the sanitary safety standards, and is applicable to materials of cup shells.
Description
Technical field
The present invention relates to plastics field, particularly a kind of cup improves polycarbonate composite material and preparation method thereof with SEBS.
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 a kind of cup and improve polycarbonate composite material and preparation method thereof with SEBS.
In order to realize object of the present invention, the present invention passes through following scheme implementation:
With SEBS, improve a polycarbonate composite material, by the raw material of following weight part, made: polycarbonate 500-520, SEBS 19-22, HMPA 2-3, attapulgite powder 12-14, Zinic stearas 4-5, hydroxyethyl meth acrylate phosphoric acid ester 20-30, dimethyl silicone oil 2-3, zinc oxide 3-4, auxiliary agent 10-12;
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.
Cup of the present invention improves polycarbonate composite material with SEBS, by following concrete steps, is made:
(1) SEBS is heated to molten state, adds HMPA, attapulgite powder, Zinic stearas, hydroxyethyl meth acrylate phosphoric acid ester, 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 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 has outside the mechanical property of good processing characteristics and resistance to cracking and excellence, and steady quality, safety and environmental protection, the harmless hygienic safety that meets of tasteless odorless, surface smoothness is good, is suitable as water tumbler case material.
