Abstract
The invention relates to a preparation method of a special CPP aluminized cast film material, which comprises the following steps: the mixed gas of ethylene and propylene is polymerized in the presence of hydrogen, nitrogen and Z-N catalyst to prepare CPP resin, 0.1 to 0.5 weight percent of antioxidant, 0.1 to 0.2 weight percent of anti-adhesion agent and 0.1 to 0.2 weight percent of slipping agent are added into the CPP resin to be uniformly mixed, and the special material for the aluminized polypropylene casting film is prepared through melt extrusion and granulation. The base resin of the special material has a sequence structure combining random copolymerization and block copolymerization, the structure can improve the crystal form and the mechanical property of the product, so that the resin shows more excellent bending property and processability, and meanwhile, the industrial problem of precipitation of the special material auxiliary agent of the casting film is solved by adding the composite auxiliary agent with high heat resistance and low precipitation, so that the special material resin is a practical functional film resin.
Description
Technical Field
The invention relates to the field of synthetic resin, in particular to a special material for a CPP aluminized casting film and a preparation method thereof.
Background
The polypropylene aluminized casting film (CPP) has the unique properties of excellent light shielding property, decoration property, barrier property, printing composite adaptability and the like, can meet the use requirements of heat resistance, chemical resistance, wear resistance, high barrier property and the like of a film, and is widely applied to the fields of food, medicine, chemical industry, electronics and the like. In 2018, the demand of the special material for domestic aluminizer reaches more than 50 ten thousand tons, only the products of companies such as Zhonghai shell, yanshan petrochemical industry and the like are used as low-grade aluminizer resin, the special material for high-grade aluminizer is all dependent on import, and typical brands are imported brands such as Bassel, nordic chemical industry, korean oil petrochemical industry and the like. Compared with the general materials, the selling price is 200-500 yuan/ton higher, the economic benefit is obvious, and the market prospect is wide. In recent years, the demand of special materials for CPP aluminizer corona layers in China exceeds 10 ten thousand tons/year, the demand is increased year by year, and the market development prospect is good. The main performance requirements of the resin are as follows: the melting finger is 8.0-10.0g/10min, low in precipitate, and good in aluminizing firmness.
The three-layer co-extrusion casting line is taken as main equipment for producing CPP (cast-in-situ) at home, the structure of the three-layer co-extrusion casting film can be generally divided into a heat sealing layer, a core layer and a corona layer, wherein the heat sealing layer needs to be subjected to heat sealing processing, the heat sealing temperature of the material is required to be low, the openness is good, and a ternary polymerization CPP raw material is generally used, and the proportion is 20%; the core layer material determines the mechanical property of the film, and generally adopts a homopolymerized CPP raw material, and the proportion is 60%; the corona layer is surface treated to have proper surface tension for printing, compounding or metallization, and binary or ternary polypropylene is generally used in 20% proportion. Correspondingly, the structure of the aluminized CPP film is a three-layer composite structure of copolymerized PP/homo-polymerized PP/copolymerized PP.
In order to meet the requirements of the surface of the aluminized CPP film product on the adhesion strength of evaporated metal aluminum, the dimensional stability of the product after evaporation and the like, the molecular structure and the performance of the special material for the core layer are required to be higher: firstly, the rigidity of the product is high, excellent stiffness is provided, and the surface of the film is prevented from being wrinkled easily in the high-temperature radiation processing process; secondly, the low molecular weight components are few, so that small molecules are prevented from being separated out, and corona and aluminizing performances are influenced; and thirdly, the auxiliary agent system has high temperature resistance and good stability, can bear high impact force during vacuum aluminizing, and ensures the surface tension and aluminizing firmness of the aluminized film. The corona-treated layer requires a MFR of 6 to 12g/l0min and is used as a three-layer co-extruded CPP film for a composite substrate, which must be corona-treated in order to improve its adhesion to ink and its composite strength with other materials. The MFR of the intermediate layer (core layer, support layer) is preferably 6 to 10g/l0min. The core layer plays a supporting role on the film, so that the stiffness and the expansibility of the film are improved, and meanwhile, the cost is reduced. The core layer is required to have excellent rigidity, so that it is mostly made of homopolymer. The core layer of the three-layer co-extrusion CPP film accounts for 60% -70% of the total film weight. Second, the good optical properties (low haze, high gloss) of the three-layer co-extruded CPP film are also primarily dependent on the core layer. The heat-sealing layer (non-treated layer) has an MFR of 6 to 12g/l0min. Besides the characteristics of slip, anti-blocking property, less precipitation amount, less volatile components and the like, the heat sealing layer needs to have good heat sealing performance, namely, the heat sealing temperature of the material needs to be wider. The heat sealing layer uses binary or ternary random copolymer, and the dosage of the heat sealing layer accounts for 15% -20% of the total film weight.
The domestic high-end CPP aluminized film production technology is still in a starting stage, and the domestic aluminized film special material mainly has the problems of more auxiliary agents, low special material modulus and the like, so that the aluminized film firmness and film stiffness are seriously influenced, and the special material performance can not meet the use requirements of downstream users on high-grade aluminized products all the time.

And (3) preparing composite low-temperature particles, mixing the composite low-temperature particles with a base film, carrying out corona treatment on the surfaces, and then carrying out vacuum aluminizing. However, the formulation of the technology has a large amount of low-temperature non-conductive liquid, which increases the industrial production cost.
