Abstract
The invention relates to PVC environment-friendly plastic. The PVC environment-friendly plastic is prepared from the following raw materials in parts by weight: 100-150 parts of polyvinyl chloride, 20-30 parts of glycidyl methacrylate, 20-40 parts of carbon black, 10-30 parts of glass fibers, 10-20 parts of polyethylene glycol terephthalate, 10-20 parts of stearic acid and 10-20 parts of an anti-ageing agent. An anti-aging plastic film provided by the invention has stability for more than 252 days at a high temperature of 150 DEG C, has thermal oxidization stability for more than 156 days in water, and has light stability for more than 187 days, so that the ageing resistance of the plastic film is greatly improved, and the service life of the plastic film is prolonged; besides, the plastic film is greatly improved in permeation resistance, water resistance, gas permeability and low temperature resistance.
Description
Technical field
The present invention relates to Material Field, specifically, the present invention relates to a kind of PVC environmentally-friendly plastic.
Background technology
Along with the extensive application of China's plastic, the demand of plastic foil is also gradually increased.Mesh
Before, a lot of enterprises utilize waste polyethylene plastics to produce plastic foil, then make all size
Packaging bag.Utilize waste polyethylene plastics strong to the plastic foil tension producing plastic foil and producing
Spend little, anti-impact force is weak, mobility is poor thus affects use.Further, this plastic foil
The most degradable, environment is had resulted in serious " white pollution ".
Plastic foil all may be sent out in its synthesis, each stage of storing and process and finally applying
Change matter, i.e. the performance depreciation of material, and such as yellowing, relative molecular weight decline, product surface
Be full of cracks, gloss are lost, and more seriously cause impact strength, flexural strength, hot strength
Decline to a great extent with the mechanical property such as percentage elongation, thus affect the normal use of film.This phenomenon claims
For aging.See in angle chemically, the still synthesis that plastic material is the most natural, all
Having certain molecular results, some of which position has some weak bonds, and these weak bonds are naturally
It is referred to as the breach of chemical reaction.The essence of ageing of plastics is nothing but a kind of chemical reaction, i.e. with
Weak bond generation chemical reaction, as oxidation reaction etc. for starting point and causes series of chemical.It
Can be caused, such as heat, ultraviolet light, mechanical stress, high-energy radiation, electric field etc. by many reasons
Deng, can independent a kind of factor, it is also possible to many factors acts on jointly.Its result is macromolecule
The molecular structure of material changes and relative molecular mass declines or generation crosslinking, thus material
Performance depreciation, so that cannot use.
Summary of the invention
It is an object of the invention to provide a kind of PVC environmentally-friendly plastic.
In order to realize the purpose of the present invention, the present invention provides a kind of PVC environmentally-friendly plastic, by following
The raw material of weight portion is made: polrvinyl chloride 100-150 part, glycidyl methacrylate
20-30 part, white carbon black 20-40 part, glass fibre 10-30 part, polyethylene terephthalate
10-20 part, stearic acid 10-20 part and antiaging agent 10-20 part.
Preferably, PVC environmentally-friendly plastic of the present invention is prepared by the raw materials in:
Polrvinyl chloride 120 parts, glycidyl methacrylate 25 parts, white carbon black 30 parts, glass fibre
20 parts, polyethylene terephthalate 15 parts, stearic acid 15 parts and antiaging agent 15 parts.
It is highly preferred that described antiaging agent is (S)-3-(1-methylcyclopropyl groups)-6-((1-phenylethyl)
Amino) pyrimidine-2,4 (1H, 3H)-diketone.
The present invention provide anti-aging plastic film 150 DEG C of high-temperature stabilities reached 252 days with
On, in water, thermo oxidative stability has reached more than 156 days, and light stability has reached more than 187 days,
The significant increase anti ageing property of plastic foil, extends service life, additionally its anti-permeability
Energy, water resistance, permeability and resistance to low temperature all improve a lot.
Detailed description of the invention
Below by way of the description of detailed description of the invention, the invention will be further described, but this is not
Being limitation of the present invention, those skilled in the art, according to the basic thought of the present invention, can do
Go out various amendment or improvement, but without departing from the basic thought of the present invention, all in the present invention
Within the scope of.
Embodiment 1
Weigh polrvinyl chloride 120 kilograms, glycidyl methacrylate 25 kilograms, white carbon black 30
Kilogram, glass fibre 20 kilograms, polyethylene terephthalate 15 kilograms, stearic acid 15
Kilogram and (S)-3-(1-methylcyclopropyl groups)-6-((1-phenylethyl) amino) pyrimidine-2,4 (1H, 3H)-two
Ketone 15 kilograms, adds high-speed mixer mixing 10min, adds in double screw extruder, through molten
Melt extrusion, the processing temperature of extruder by feed opening to die orifice be followed successively by 165 DEG C, 173 DEG C,
180 DEG C, 192 DEG C, engine speed is 150rpm, and vacuum is 0.4Mpa, discharging and get final product.
Embodiment 2
Preparing PVC environmentally-friendly plastic according to the same manner as in Example 1, difference is not
Use (S)-3-(1-methylcyclopropyl groups)-6-((1-phenylethyl) amino) pyrimidine-2,4 (1H, 3H)-diketone.
Experimental example
National Standard of the People's Republic of China GB/T 7141-2008 is used to carry out plastic hot
Degradation.Result is as follows: the plastics of embodiment 1 have reached 280 for 150 DEG C of high-temperature stabilities
My god, in water, thermo oxidative stability has reached 170 days, and light stability has reached 200 days；And implement
The plastics of example 2 have reached 210 days for 150 DEG C of high-temperature stabilities, and in water, thermo oxidative stability reaches
By 110 days, light stability reached 130 days.As can be seen here, adding antiaging agent can pole
Improving greatly the anti ageing property of plastic foil, the result of embodiment 1 is carried out with the result of embodiment 2
Relatively, difference has statistical significance (P < 0.05).
