METHOD FOR PREPARING INORGANIC COMPONENT REINFORCED HIGH-WEATHER-
RESISTANCE PVC FILM
The present disclosure relates to the field of organic poly- mer materials, and particularly relates to a method for preparing an inorganic component reinforced high-weather-resistance PVC film.
Polyvinyl chloride (PVC) is one of the five general-purpose plastics and is widely used around the world. PVC has the charac- teristics of good flame retardant property, high strength, excel- lent wear resistance, strong chemical corrosion resistance, low gas and water permeability, and low production cost, etc. It is widely used in building profiles and pipes, artificial leather, cables, packaging materials, etc. However, its characteristics of brittleness, poor thermal stability, easy aging and easy genera- tion of static electricity restrict its applications.
Inorganic ultraviolet absorbents such as nano zinc oxide and nano titanium dioxide have the ability to absorb a broad spectrum of ultraviolet wavelengths. Adding them to PVC can effectively prevent the damage of ultraviolet rays in sunlight to the PVC structure, delay the aging of PVC materials, and enhance its weather resistance.
Graphene has a carrier mobility of up to 15000cm™/ (V's) at room temperature, and it has good electrical conductivity. Doping graphene in PVC can give PVC certain electrical conductivity and antistatic properties. In actual applications, graphene can pre- vent the electrostatic damage caused by the accumulation of elec- trons in one place. In addition, graphene has absorption in the ultraviolet band of 100-281 nm, and can shield ultraviolet rays with wavelengths greater than 281 nm through reflection. Adding graphene to PVC can also reduce the damage of ultraviolet rays to the PVC structure and enhance its weather resistance.
However, the graphene surface is inert, and the graphene sheets have strong van der Waals forces, which are difficult to disperse and aggregate together, and have poor compatibility with polymer substrates. Graphene oxide has oxygen-containing groups such as hydroxyl and carboxyl groups, and the interlayer repulsion is large and easy to disperse. During the high-temperature vulcan- ization process, graphene oxide will remove some oxygen-containing groups and will be reduced to graphene, which has good electrical conductivity and UV resistance.
In the Chinese patent CN201410406955.7, in-situ polymeriza- tion method is adopted; graphene emulsion is added to a vinyl chloride monomer suspension polymerization system, to obtain gra- phene/PVC resin. This method requires pretreatment of graphene, and the addition of graphene may produce a certain impact on the performance of PVC during polymerization.
Object: an Object of the present disclosure is to provide a method for preparing an inorganic component reinforced high- weather-resistance PVC film which is simple and mild in condition.
Technical solutions: the method for preparing the inorganic component reinforced high-weather-resistance PVC film comprises the following components: 80-100 parts of polyvinyl chloride res- in, 0.1-3 parts of graphene oxide, 0.1-3 parts of an inorganic ul- traviolet absorbent, 5-10 parts of calcium carbonate, 1-5 parts of a lubricant, 5-10 parts of a plasticizer, 0.1-3 parts of pol- ysilsesquioxane, 1-5 parts of an organic tin heat stabilizer and 3-10 parts of ACR.
In the present disclosure, the method for preparing the inor- ganic component reinforced high-weather-resistance PVC film com- prises the following steps: plasticizing and milling materials which are uniformly mixed in proportion, taking out sheet-shaped materials after the materials are fully and uniformly plasticized, placing the materials into a preheated mold, performing hot press- ing on the materials in a flat vulcanizing equipment at 130-170°C, taking out the mold after the hot pressing is finished, and dis- charging to obtain the inorganic component reinforced high-
weather-resistance PVC film.
According to the method of the present disclosure, the inor- ganic ultraviolet absorbent is any one or a mixture of more of nano zinc oxide, nano titanium dioxide, barium sulfate and lead sulfate.
According to the method of the present disclosure, calcium carbonate is one or two of nano calcium carbonate, light calcium carbonate, ground calcium carbonate or activated calcium car- bonate.
According to the method of the present disclosure, the lubri- cant comprises any one of calcium stearate, oxidized polyethlene wax, stearic acid, stearin, paraffin and polyethylene wax.
According to the method of the present disclosure, the plas- ticizer is any one or a mixture of more of dioctyl phthalate, di- iso-decylphthalate, diisooctyl phthalate, diisononyl phthalate, dibutyl phthalate, diisobutyl phthalate, butyl benzyl phthalate, dimethyl phthalate, diethyl phthalate and dicyclohexyl phthalate.
According to the method of the present disclosure, pol- ysilsesquioxane comprises any one of polyhedral oligomeric silsesquioxane and ladder-like polysilsesquioxane.
Graphene has good conductivity, and a small amount of gra- phene and the like can be added into PVC resin to enable good an- tistatic performance of PVC; meanwhile, the graphene has certain ultraviolet-proof capability on ultraviolet rays. After the gra- phene is added into the PVC resin, a small amount of inorganic ul- traviolet-proof agent is added to enable good ultraviolet-proof performance of the PVC, and the damage to a PVC structure can be reduced. In addition, additives are added through a melt blending method after polymerization of the PVC resin is completed, thus the influence on PVC polymerization can be greatly reduced, and the performance of the PVC is improved. Polysilsesquioxane is adopted, so the mechanical property and the flexibility of the PVC film can be improved through organic and inorganic components of polysilsesquioxane.
The present disclosure will be further described in detail below.
