Description
Technical field
The invention belongs to modification polyethylene terephthalate manufacture field, particularly relate to a kind of resident identification card with PETG card base, the invention still further relates to the manufacturing process of this PETG card base.
Background technology
PETG (modification polyethylene terephthalate) is that PET (polyethylene terephthalate) is through glycol-modified noncrystalline copolymerization fat, thermoforming process producing drink bottle, packing bottle, bucket etc. are generally adopted in the processing of existing P ETG, or adopt and extrude explained hereafter PETG film, sheet materials such as curtain coating, blowing, stretching, product is mainly used in produces food, medicine, toy, five metals packing.
Although adopt the PETG sheet material of blowing, casting and stretching explained hereafter to have excellent physical and mechanical properties, chemical resistance, air-tightness, processing characteristics and resistance to low temperature, and have be difficult for broken, be as good as smell, nontoxic, transparency advantages of higher, but adopt curtain coating, blowing, drawing process production product that flow liner, uneven thickness are arranged, percent thermal shrinkage is big, defectives such as uncontrollable product roughness, product have flow liner and uncontrollable roughness to influence the printing performance of product and make anti-counterfeiting mark and handle; Product thickness is uneven and percent thermal shrinkage is excessive, and behind the product laminated (heat seal), under the reactive force influence, yielding, warpage can not be used for fabrication so adopt with curtain coating, blowing, drawing process production product.
The raw material that PVC card base uses is a kind of chlorinated products as PVC (polyvinyl chloride) resin, and its offal treatment is improper, very easily produces the dioxin contamination environment; PVC, ABS card base see under the conditions such as light, high temperature, low temperature easily decompose, color-changeable shape-changeable, fragmentation, phenomenons such as stress albefaction are arranged, work-ing life is short, is generally 2 years, can't satisfy the requirement that the identity card time limit of service is at least 10 years.
S-generation resident identification card is made up of the heat seal of multilayer card sill, and material must have heat sealer preferably, guarantees that identity card does not ftracture, do not peel off aliquation in using.
Summary of the invention
The purpose of this invention is to provide a kind of nontoxic, ageing-resistant, performance is good, the resident identification card of long service life is with PETG card base.
Another object of the present invention provides the manufacturing process of above-mentioned PETG card base.
Technical scheme of the present invention is the characteristics according to PETG, and selecting the PETG resin is main raw material, adopts new technology--five roll-ins are prolonged processes and are made PETG card base, are used for packaging electronic chip manufacturing s-generation resident identification card.
PETG is a particulate ball-type structure, has higher density compared with cylindric particle round shaped grain, and the chemically-resistant medicament can cause the fracture of PETG polyester chain when high temperature process, causes that the molecular resin amount reduces and the finished product rerum natura reduces; The PETG material has than strong tack simultaneously, easy roll banding, the product meltbility is not as PVC and ABS material, product is prone to flow liner, be difficult to control melt pressure, the procedure for producing parameter is big, and the present invention develops new prescription, guarantee that PETG has rolling processing performance preferably, the technical parameter of production control simultaneously determines it is the gordian technique of implementing this project.
In the PETG calendering formation process, because the decomposition of raw material forms a large amount of bubbles in sheet surface, the cooling back forms pit, can occur white point (spot) during printing, causes the printing substandard products, influences printing quality.For solving this defective, the present invention adopts the planet degassing extruder on technology, both satisfied deaeration requirement on the technology, makes the plasticizing material to deliver to the rolling press continuous production continuously by rotary conveyor again, the homogeneity of material temperature is increased, reduce product current mark phenomenon.Moreover this technology installs additional cuts bubble assembly, cuts the bubble guide wheel preceding the installing additional of formed product roller (No. three rollers), makes the Ka Jinei bubble be extruded release in a large number, with install additional before compare and reduce bubble 90%, improve the surface printing performance of card base greatly.
The PETG raw material need be crushed to the 40-60 order, could produce plasticizing effect preferably, it is too small to cross grit number as particle, it has higher density compared with cylindric particle round shaped grain, and the chemically-resistant medicament is in forcing machine is plasticated, formation pellet nuclear, the inequality of plasticating, calendering back product roughness is big, can't satisfy service requirements.
Raw material after the pulverizing needs drying, and the water molecules in the PETG raw material can cause the fracture of PETG polyester chain when high temperature process, causes that the molecular resin amount reduces and the finished product rerum natura reduces, and causes that easily the product physicals does not reach requirement.
The objective of the invention is to realize by following measures:
