Abstract
The invention discloses a high oxygen resistant coating, a preparation method and a coating method, wherein the high oxygen resistant coating is prepared from the following components in percentage by weight: 30-65% of acrylate hard monomer; 5-20% of acrylate soft monomer; 0.2 to 1.5 percent of pre-crosslinking monomer; 5-25% of post-crosslinking monomer; 0.01-15% of functional substances. According to the invention, the acrylate copolymer is obtained by bulk polymerization and is mixed with the acrylate copolymer in an internal mixing manner, so that the functional substance is coated more uniformly by the copolymer in a molten state, and the filling effect of the functional substance on the copolymer is better. The mode of filling before curing is adopted to ensure that the filling of each functional substance is effective gap filling. The coating has better effects of blocking oxygen diffusion channels and prolonging the diffusion path of water vapor, and the coating also has better oxygen barrier property.
Description
Technical Field
The invention relates to the field of coating preparation, in particular to a high-oxygen-resistance coating, a preparation method and a coating method.
Background
Polyethylene terephthalate (PET) films are known for their excellent sealability, clarity, high temperature resistance and tensile strength, and can meet most packaging requirements. In recent years, PET films have become important packaging materials in the fields of food, medicine and cosmetics. There is therefore an increasing demand for high performance and new functionality of PET films, in particular oxygen barrier properties. Because the coating has simple synthesis process, low equipment requirement, multiple functions and good adhesion with the base material, the coating is one of the most rapid and practical methods for improving the oxygen barrier property of the PET film.
The invention aims to provide a high oxygen barrier coating and a preparation method thereof, which are used for improving the oxygen barrier of a PET film.
Disclosure of Invention
The invention achieves the aim, and the first aspect of the invention provides a high oxygen barrier coating, which has the following specific technical scheme:
the high oxygen resistant coating is prepared from the following components in percentage by weight:
30-65% of acrylate hard monomer;
5-50% of acrylate soft monomer;
0.2 to 1.5 percent of pre-crosslinking monomer;
5-25% of post-crosslinking monomer;
0.01-15% of functional substances.
In some embodiments, the acrylate hard monomer is one or more of methyl methacrylate, styrene, isobornyl acrylate, vinyl acetate, isobornyl methacrylate; the acrylic acid soft monomer is one or more of methyl acrylate, ethyl acrylate, butyl acrylate, isooctyl acrylate and the like; the pre-crosslinking monomer is one or more of divinylbenzene, tetramethylcyclotetrasiloxane and diallyl maleate; the post-crosslinking monomer is one or more of acrylic acid, methacrylic acid, hydroxyethyl acrylate, hydroxyethyl methacrylate, hydroxypropyl acrylate, butylene glycol, maleic acid, fumaric acid and maleic acid liver.
In some embodiments, the initiator is one or more of benzoyl peroxide, azobisisobutyronitrile, cumene hydroperoxide, and di-tert-butyl peroxide.
In some embodiments, the functional substance is a nano inorganic powder, and the nano inorganic powder is one or more of nano silica, nano titanium dioxide, nano alumina, nano montmorillonite, diatomite, and graphene oxide.

In some embodiments, the functional substance is shellac.
The second aspect of the invention provides a preparation method of a high oxygen barrier coating, which comprises the following steps:
step 1, adding an acrylate hard monomer, an acrylate soft monomer, a pre-crosslinking monomer, a post-crosslinking monomer and an initiator into a reaction vessel, and reacting for 4-8h at a constant temperature of 40-110 ℃;
step 2, cooling to room temperature, taking out solid substances in the reaction system, drying and grinding into powder;
step 3, uniformly mixing and dispersing the powder and the functional substance, and then banburying;
and 4, cooling, taking out the banburying product generated in the step 3, drying, grinding into powder, and dissolving in a solvent to obtain the high oxygen resistant coating.
In a third aspect of the present invention, a method for coating a high oxygen barrier coating is provided, wherein a curing agent is added to the high oxygen barrier coating before coating.
In some embodiments, the amount of the curing agent is 0.5-2.5% of the solid content of the coating, and the curing agent is one or more of metal acid ester, metal chelate, metal salt, isocyanate, organosilane, polycarbodiimide, ethylene imine, propylene imine, epoxy resin and amino resin.
The invention has the beneficial effects that:
the invention combines the acrylate copolymer with the functional substance, limits the movement of molecular chain segments, reduces the free volume and reduces or blocks the diffusion path of oxygen molecules through the cross-linked structure formed by the functional monomer. Then filling the functional substance in the gaps of the solidified molecular chain segments, further reducing the free volume and simultaneously prolonging the diffusion path of the water vapor molecules. In addition, the acrylate copolymer is obtained by bulk polymerization and is mixed with the functional substance in an internal mixing mode, so that the functional substance is coated more uniformly by the copolymer in a molten state, and the filling effect of the functional substance on the copolymer is better. The mode of filling before curing is adopted to ensure that the filling of each functional substance is effective gap filling. The coating has better effects of blocking oxygen diffusion channels and prolonging the diffusion path of water vapor, and the coating also has better oxygen barrier property.
