Description
Technical field
The present invention relates to environmentally-friendly plastic technical field, be specifically related to the environment-acceptable performance plastics preparation method that a kind of rare earth compound is coupling agent.
Background technology
The application of plastics in fields such as modern industry, agricultural, daily lifes is more and more extensive, and there be close contacting in it and industrial and agricultural production and each department of national economy.But plastic industry encounters the two problems being badly in need of solving at present: " white pollution " of waste plastic and the starting material-petroleum-based energy of synthetic resins day by day in short supply, therefore solve the attention of the supply and demand problem of plastics and environment compatibility also just expert extremely both at home and abroad.Along with the development of petrochemical complex and improving constantly the requirement of plastics cost performance, inorganic mineral more and more receives the concern of people as plastic filler.Inorganic mineral uses its two large function of major embodiment as filler, and the first increases volume, reduces costs; It two is improve polymer processing performance and physical and chemical performance.
" environment-acceptable additives for plastics " refers to add in plastics and plastics and soil can be impelled to assimilate or impel plastics can adapt to the comprehensive treatment mode of the landfill of rubbish, burning, compost or degraded, slows down the analog assistant to environmental stress.This is a relative concept, macroscopically says that being conducive to the auxiliary agent that plastics and environment assimilate all belongs to this category." environment-acceptable additives for plastics " must possess following 3 technology essential factors: the use properties not affecting general-purpose plastics after (l) and plastic blend; (2) under the effect of the natural condition such as environmental element light, heat, bacterium, microorganism, wind, stress and acid, alkali, water or the human factor such as compost and burning, the assimilation degree of general-purpose plastics and environment can be improved; (3) the own environment-acceptable of auxiliary agent.
Because inorganic mineral derives from nature, can return in nature again, because of but the good environment-acceptable auxiliary agent of a class; Water in soil and the macromolecular material of carbonic acid gas to landfill work hardly, be commonly called as 200 years not rotten, but there is erosion action rapidly to the inorganic mineral powder in plastics, after calcium carbonate becomes Calcium hydrogen carbonate, resultant has certain water-soluble, leave micropore after departing from plastics, greatly can increase plastics and touch oxygen area, be conducive to the aging of goods and disintegration.
The inorganic minerals such as calcium carbonate, rhombspar, talcum powder can think the material healthy and safe to people, after plastics are landfilled, can not form and pollute, can not bring any harm to ecotope during these mineral powder back to natures to underground water.Chemical oxygen demand (COD) is commonly used to weigh the degree that reducing substances pollutes in water, and the CODcr value of the biological degradation PE film of starch-containing 15% is 96, and the CODcr value containing the PE film of 15% inorganic mineral is 0.
In solid refuse, often run into the material of chloride element, the various poisonous and harmful substances comprising Dioxins may be generated in combustion, calcium carbonate have the hidden danger may eliminating chlorine-bearing compound, also likely absorb HCL, H
2the sour gas such as S, reduce incineration ashes to atmosphere of harmful elements quantity.At the refuse bag that Japan is prevailing since the eighties, explicitly called for water-ground limestone content to reach more than 30%, main is exactly to protect incinerator and the Thorough combustion being conducive to plastics bag.
Summary of the invention
The environment-acceptable performance plastics preparation method of object of the present invention provides to be a kind of rare earth compound be coupling agent, the environment-acceptable performance plastics prepared by it have protection of the environment, the features such as energy-saving and emission-reduction.
In order to solve the problem existing for background technology, the present invention is by the following technical solutions: a kind of rare earth compound is the environment-acceptable performance plastics preparation method of coupling agent, it is characterized in that prepared environment-acceptable performance plastic packets is containing vinyon, calcium oxide (or calcium carbonate), rare earth compound, for 100 parts, wherein vinyon accounts for 60 parts, calcium oxide (or calcium carbonate) accounts for 39.9 parts, and rare earth compound accounts for 0.1 part.
Described environment-acceptable performance plastics preparation process is:
Take 1250 appropriate order calcium oxide (or calcium carbonate) in high-speed mixer, stirring and drying at 110 ~ 120 DEG C;
Add 0.1% rare earth compound coupling agent, carry out the coated 8 ~ 10min of coupling, then take PE resin by CaO (CaCO3): PE=40:60 (mass ratio) and add in high-speed mixer, mix rear discharging;
Through twin screw extruder extruding pelletization, obtain calcium oxide masterbatch (or calcium carbonate masterbatch);
Calcium oxide masterbatch joins blowing in Blown-film line and obtains environment-acceptable PE film (thickness: 0.015 scholar 0.001mm);
Unit temperature controls: 155 ~ 170 DEG C, I district, II 170 ~ 175 DEG C, district, III 175 ~ 180 DEG C, district, 180 ~ 190 DEG C, IV district.
Described blowfilm shaping condition is: blow-up ratio is about 1:6, and pulling speed is about 30m/min, and screw speed is 35-40r/min.
The advantage that the present invention has:
1, rare earth compound is to CaO and CaCO
3there is the coated function of coupling, but CaO compares CaCO
3alkalescence strong, CaO ratio is easier to class rare earth compound by formation of chemical bond title complex, thus rare earth compound plays the coated effect of coupling relatively better to CaO, improves the consistency of CaO and PE, thus the mechanical property of PE/CaO environment-acceptable film is improved;
2, rare earth compound and calcium oxide have good synergistic effect, and because rare earth compound produces free radical under action of ultraviolet light, induction PE splitting of chain, makes DeR occupy dominant position; Along with the exposure gradually of CaO, absorb the H in air
2o and CO
2, thus increase the transmitance of gas, further promote the generation of free radical and photodegradatively to carry out.
