Description
Technical field
The present invention relates to a kind of filtering material, especially relate to a kind of boiomacromolecule that can degrade fully and melt and spray cotton preparation method.
Background technology
Along with the enhancing of social development and human environment consciousness, its Application Areas of filtering material more and more widely, main application fields comprises aspects such as medicine, pharmacy, electronics, automobile, water treatment.The raw material of existing filtering material generally all are petroleum chemicals such as polyolefin and polyester.Although the petrochemical industry material is less than glass fibre in the harm to environment and human body, yet its service life is limited, belongs to easily-consumed products, a large amount of uses harm very big to environment.In recent years, PLA (PLA) can be used as the substitute of petrochemical industry material as a kind of novel biodegradable ep-type material, causes people's attention gradually.
PLA (PLA) degradative plastics is a kind of aliphatic polyester, it is a kind of thermoplasticity bioabsorbable polymer material with crystallinity, transparent, easy processing, fully biodegradable, its vitrification point is 50～60 ℃, fusing point is 170～180 ℃, density is 1.25g/cm3, and mechanical properties such as intensity, elasticity are similar to polystyrene (PS) with the transparency.PLA is to be main production raw material with agriculture renewable resource (commonly used corn), produce water white liquid-lactic acid through modern biotechnology, lactic acid generates graininess boiomacromolecule polyester material-PLA (PLA) through special chemical polymerization process.The PLA particle that is made by the corn extract is called " corn plastics ".The advantage of PLA is can biodegradation, and the method for degraded has multiple, as: mix in the fertilizer and decompose.The temperature of this composting conditions is 60 ℃, and relative humidity is 90%.The dominant mechanism of its degraded is hydrolysis, comes catalysis by temperature, by bacterium residual chip is nibbled then, can resolve into carbon dioxide and water, and the regeneration period short (about 1～2 year), does not pollute the environment.PLA can be applied to the huge packaging for foodstuff field of consumption, as disposable mess tin, plate, plate, disposal plastic cup etc.
The PLA fiber applications in the filtering material field, external existing precedent, its preparation method generally is, earlier the PLA fiber is carded to fibre web, be processed into filter material through acupuncture or method such as hot sticky again, but this PLA filter material performance has limitation, lower as filter efficiency, Rong Chenxiao, and material is compressed easily (because the initial modulus of PLA fiber is lower in preparation process, easy deformation under little load effect, used pure PLA fiber material in combing or acupuncture course is compressed easily), the pressure drop of product higher (when material is compressed, high pressure drop taking place in the time of may causing the filtering substrate of air draught in passing filter), this is unfavorable to preparation of product, also expends the energy.Therefore, a patent of Sweden (referring to proposing a kind of solution among the WO2008140384 (A1): add polyester components in the PLA fiber, can avoid being compressed in carding process, adds polyester components simultaneously and also can play cementation by mixed fiber.This fiber web that PLA fiber and polyester fiber are mixed through combing formation, the method of reinforcing again, though solved the compressed problem of material, but the filtering substrate filter efficiency of preparing is lower, can not satisfy the instructions for use of high-performance filter (as the filter more than the F7 rank among the EN779), still be badly in need of requiring to solve.
Summary of the invention
The object of the present invention is to provide can bury after a kind of use to abandon, can degrade fully under special time and environment, the boiomacromolecule that can degrade fully that can not cause public hazards to pollute melts and sprays cotton preparation method.
The present invention includes following steps:
1) preparation matrix resin (PLA) modified colloidal particle;
2) prepare the boiomacromolecule that to degrade fully and melt and spray cotton.
In step 1), the described method for preparing the matrix resin modified colloidal particle can be:
Matrix resin, modified master batch and auxiliary agent are dropped into batch mixer carry out batch mixing, then mixed raw materials is put in the double-screw extruding pelletizing machine, through melt extruding into line, cool off, pelletizing then obtains the matrix resin modified colloidal particle;
Described matrix resin, modified master batch and auxiliary agent are matrix resin 70%～90%, modified master batch 9%～29.8% and auxiliary agent 0.2%～1% by mass percentage; The described batch mixing that carries out, preferably earlier dry 10～30min carries out batch mixing again; The described technological parameter that mixed raw materials is put in the double-screw extruding pelletizing machine is as follows: utilize auxiliary feed system reinforced, rate of feeding can be 60～120r/min, main-machine screw rotating speed and can be 250～350r/min, processing temperature and can be 170～180 ℃, die pressure and can be 1.0～6.0MPa, and the speed of described pelletizing can be 200～400r/min;
Described modified master batch is optional from poly butyric ester (PHB), polycaprolactone (PCL), poly butyric-valerate (PHBV), dihydroxylic alcohols dicarboxylic acids aliphatic polyester (PBS), at least a in fat/aromatic copolyesters (Ecoflex) etc.; Described auxiliary agent can be selected from ATBC (ATBC), ethylenebisstearamide (EBS), at least a in the dolomol etc.Described fat/aromatic copolyesters (Ecoflex) can adopt the fat/aromatic copolyesters (Ecoflex) of German BASF AG.
In step 2) in, the boiomacromolecule that described preparation can be degraded fully melts and sprays cotton method and can be:
In matrix resin modified colloidal particle feeding screw extruder, melt extrude melt, be transported in the measuring pump through filter, be transported to spray silk die head after the metering, add under the hot-air winding-up effect in the spinneret orifice both sides, promptly can be made into the matrix resin meltblown fibers, and add the type of being solidified into by himself waste heat on receiving system, the boiomacromolecule that acquisition can be degraded fully melts and sprays cotton.
The described temperature that melt extrudes melt can be 170～180 ℃; The temperature of described hot-air can be 170～180 ℃.
Melting and spraying cotton filtering material with existing P P compares, the prepared degradation biological macromolecule fully of the present invention melts and sprays cotton to have product and can bury after use and abandon, through test, be buried in the landfill 1～2 year with regard to fully biodegradable, so have advantages such as can not causing the public hazards pollution.
