Abstract
The invention discloses an anti-fog crystal film and a preparation method thereof. The anti-fog crystal film is prepared by uniformly mixing the following components in percentage by weight: 60-90% of polypropylene resin, 1-15% of a static inhibitor, 0.5-10% of an anti-blocking agent and 1-20% of copolymerization polypropylene; the mixture is then subjected to kneading, smelting, milling, extruding, cooling, drying, cutting, and film blowing, and the anti-fog crystal film is obtained. The anti-fog crystal film, provided by the invention, is prepared from the raw material of polypropylene, has excellent anti-fog and heat-seal functions, is smooth, resistant to penetration and transparent, and can retain freshness for a long time.
Description
Technical field
The present invention relates to film and preparation method thereof, be specifically related to a kind of antifog crystal film and preparation method thereof.
Background technology
Antifog crystal film is a kind ofly to prevent that steam from forming knot mist and affecting the functional film of transparency at film surface, is mainly used in plastic sheeting for farm use in early days.Along with the change of people's consumers demand, food product pack is to the future development such as convenient, healthy, healthy, fresh.In the packing of various transparent frozen product, high temperature constant temperature instant food, sour-sweet fruit spreads and fresh vegetables and fruits class, for preventing that water smoke affects visual effect, must adopt antifog crystal film to pack.Antifog crystal film in the market exists that anti-fog performance is poor, smoothness is low, easy puncture, shortcoming that transparency is low.
Summary of the invention
The invention provides a kind of antifog crystal film and preparation method thereof, its object is to take the antifog crystal film that polypropylene makes as raw material, and it has excellent antifog and heat sealability, high smoothness, paracentesis resistance, high-clarity can be fresh-keeping for a long time.
The object of the invention is to be achieved by following component and using method.
An antifog crystal film, is characterized in that, according to weight percent meter, by following raw materials according, is processed, and the weight percent of each raw material is respectively: acrylic resin 60-90%, static inhibitor 1-15%, antiblocking agent 0.5-10%, Co-polypropylene 1-20%.
Further, described antiblocking agent is the polymkeric substance of organosilicon polymer or methacrylic ester.
Preparation method of the present invention, comprises the following steps:
Acrylic resin, static inhibitor, antiblocking agent, Co-polypropylene that a gets said ratio mix, and in kneader, in temperature, are to mediate 6-10 minutes at 180-200 ℃, take out that cooling to obtain antifog crystal polypropylene standby;
B sends into the antifog crystal polypropylene of a step in the hopper of single screw extrusion machine, carry out melting, mixing, extrude, after cooling, dry, blank, blown film and get final product.
Further, the Screw Extrusion technological temperature in described step b is controlled at 220-270 ℃.
Wherein, described static inhibitor is static Science and Technology Ltd. of Dongguan City Fiat.
Beneficial effect of the present invention:
1, effectively avoid occurring the adverse consequencess such as the bonding, flaw in film later stage, brilliant point;
2, in production engineering, control its crystallisation process, reduce the mist degree difference of polypropylene self, to reach low haze effect;
3,, by application antiblocking agent, because it has good optically, the transparency improves greatly;
4, product surface is smooth, and frictional coefficient is low;
5, product can not produce scuffing, and glossiness is high.
