Abstract
The invention relates to a master batch for a high-resistance polyester bottle and a preparation method thereof. The master batch comprises the following raw materials in percentage by mass: 0.01-1 percent of nano-TiN, 0.1-1 percent of compatilizer and the balance of polyester slices. The preparation method comprises the following steps of: uniformly mixing the raw materials according the mass percentage; putting into a blending machine for blending at the temperature of 200-300 DEG C for 1-5 hours; and granulating to obtain the master batch, i.e., the master batch for the high-resistance polyester bottle. The master batch has the advantages that: the resistance of a polyester resin bottle is enhanced; a very small quantity of nano-materials are added, so that the master batch can be directly applied to the various conventional bottle making machines without updating equipment; and the colorless and transparent appearance of the polyester bottle is kept, and the resistance is increased by over 10 times.
Description
[technical field]
The present invention relates to the pet bottle technical field, specifically, is a kind of master batch and preparation method of high-barrier pet bottle.
[background technology]
Since have transparent, intensity is high, purposes is wide and characteristics such as recyclable, Nan Gua polyester bottle slice becomes the wrapping material that the human consumer likes, is enjoying great success.Seldom have the polymeric staple kind that the so high demand growth speed of polyester bottle slice can be arranged, even if in developed country, polyester bottle slice growth of requirement speed is still near double figures.
Yet the lucky son of this plastic industry neither not have flaw.Polyester bottle slice occurs after trevira, and extensive new device causes oversupply.Polyester producers is the same with the chemical industry other products to be faced with higher raw materials cost pressure.Such as new market such as Beer Bottle because technical restriction makes it fail as 20 oz. for beverages bottles many years ago, to obtain the breakthrough in the application.In the face of these challenges, some observer thinks that the commercialization of new polyester packages product remains time, and the others admits that the rate of growth of some regional polyester bottle slice is slowing down in the world.
Chinese patent publication number CN1317507 discloses and has supplied the method for manufacture of polyester with low content of acetaldehyde bottle with copolyesters; In polyethyleneterephthalate (PET) polymer; Add appropriate modifier, reducing in the special Aguarius manufacturing processed, the acetaldehyde generating capacity that causes because of the thermo-cracking side reaction; This properties-correcting agent comprises stablizer and 1 grade of inhibitor, and wherein stablizer is an inorganic phosphorous compound, and its addition is in 0.003 to 0.5% weight range based on the weight of whole copolyesters multipolymers, and this 1 grade of inhibitor is for containing Ca
2+The hindered phenol type inhibitor, its addition is in 0.005 to 5.0% weight range based on the weight of whole copolyesters multipolymers, is not added with the by-product acetaldehyde generating capacity of this properties-correcting agent, has and can reduce by 30% the effect of improving at least.
Chinese patent publication number CN1408000 discloses the method for preparing modified polyester bottle resins, and the present invention is the method that preparation has the high molecular weight copolyester bottle resins of excellent melt characteristic.This method comprises makes diacid or diester component and diol component reaction to form the step of modification polyethylene terephthalate; Wherein diol component exists so that stoichiometric ratio is excessive; Diacid or diester component and diol component must comprise at least 7% comonomer together, and the residuum of diacid component is that the residuum of terephthalic acid or DMT. Dimethyl p-benzenedicarboxylate and diol component is a terepthaloyl moietie; The modification polyethylene terephthalate is copolymerized to the limiting viscosity between about 0.25dl/g and the 0.40dl/g at melt in mutually, thereby forms the copolyesters prepolymer.After this copolyesters prepolymer polymerization in solid phase has at least approximately limiting viscosity and the HMW bottle resins that is lower than the solid phase density of 1.413g/cc of 0.70dl/g with formation.
Chinese patent publication number CN1043658 discloses the equipment and the method for two-step approach production P E T pet bottle; The processing technique field that belongs to food product pack; At first the raw material after the drying treatment is outpoured bottle base through injection moulding machine; Bottle base by stretch blow machine stretch blow moulding, adds collet then again through the baking oven second-heating; Compared with present technology the present invention has simple in structure, easy to manufacture, with low cost, and installation, maintenance is convenient.
Chinese patent publication number CN1385292 discloses the working method and the equipment of heat-resistance polyester bottle, is raw material with the PET polyester, is annotated by injection moulding machine and processes bottle base; The bottleneck of bottle base is handled through crystallizer heating, crystallisation by cooling; Again that the pipe portion of bottle base is softening through heater heats, then to put into the stretch blow mould and carry out blow molding, the stretch blow mould need be heated to about 100 ℃; The stretch blow moulding process is by a pre-blowing, and secondary high-pressure bottle blowing and three low pressure are cooled off bottle blowings; The whole machining process process is to improve the percent crystallinity of PET, thereby improves heat resisting temperature, adapts to the production needs of heat filling beverage, makes bottle meet heat and does not shrink.
Chinese patent publication number CN101172525 discloses high-performance double-layer polyester bottle, and a kind of high-performance double-layer polyester bottle is that to choose PET be that resin is done skin; Choose the another kind of high barrier vibrin of proper ratio and do internal layer; And internal layer not additive color is female, adopts extra quality/double coloured plastic injection machine or double-deck injection moulding machine altogether, cooperates double-deck preform mould; After injection perhaps is injected into double-deck base synchronously altogether at twice, form through bottle base heated mechanical preheating and two-way stretch blowing machinofacture again; Beneficial effect of the present invention: have more high barrier, better wholesomeness can be used for multiple eating article such as can beer, fruit juice, medicine not adding or lacking under the situation of adding preservative agent.
Chinese patent publication number CN1539624 discloses method of manufacture of high temperature resistance polyester bottle and products thereof, and this method is to make bottle base, heating bottle blank earlier; Two-way stretch bottle base in mould remains on the bottle after stretching in the mould, after being blown into 160～240 ℃ hot gas and heating 0.5～5 second toward the bottle inner chamber; Be blown into and be lower than 100 ℃ of cold air, bottle was got in die sinking when bottle was cooled to below 100 ℃, wherein hot gas pressure 0.5～4.0Mpa; Cold air pressure 2.5～3.0Mpa, 60～100 ℃ of die temperatures; Utilize this method can make pet bottle obtain best crystallization and typing effect, improve the pet bottle thermotolerance, make the hot filling temperature of pet bottle bring up to 115 ℃, and mold sticking do not occur, improved production efficiency, reduce production costs.
At present, do not see the report of employing nano TiN as the pet bottle agglomerate material of high-barrier agent.
