Abstract
The invention relates to a paint for a polyamide resin film gas-barrier layer, which comprises an ethylene-vinyl alcohol copolymer, a polycarboxylic acid polymer, calcium oxide of which the surface is coated with water-insoluble components, and silicon oxide. The mole ratio of OH groups to COOH groups in the ethylene-vinyl alcohol copolymer and polycarboxylic acid polymer is 0.05-0.1; and the mole number of COOH groups in the polycarboxylic acid polymer is 3.5 times of that of the calcium oxide and silicon oxide. The gas-barrier layer paint provided by technical scheme still has higher gas-barrier property than before in a high-humidity environment, and still maintains excellent gas-barrier property in a high-temperature high-humidity environment.
Description
Technical field
The invention belongs to paint field, specifically refer to a kind of polyamide resin gas barrier layer coating.
Background technology
The thermoplastic resin film such as polyamide membrane, polyester film is because intensity, the transparency, formability are excellent, therefore as wrapping material and for purposes widely.But, these thermoplastic resin films are because the perviousness of the gases such as oxygen is large, so when processing the packing of food, makeup, medical treatment product, agricultural chemicals etc. for normal food, boiling, during prolonged preservation object, its content can go bad because seeing through the gases such as oxygen of film sometimes.
Therefore, surface at this resin film generally will apply one deck gas barrier layer, now use with document in all exist in order to show the gas barrier property of height in the technical scheme recorded, heat treated that must be at high temperature or for a long time heat treated, when therefore gas barrier layer is manufactured, need a large amount of energy, therefore the load for environment improves.
Summary of the invention
The object of the invention is to realize in the situation that environment is not produced the material of burden, although can make, use water-soluble polymers but still have than in the past high gas barrier property under high humidity, even and if also maintain the coating of excellent gas barrier property under hot and humid degree environment.
The present invention is achieved by the following technical solutions:
A gas barrier layer coating, multipolymer, polycarboxylic acid series polymkeric substance, surface calcium oxide and the silicon oxide of slightly water-soluble composition coating that includes ethene and vinyl alcohol; OH base in the multipolymer of ethene and vinyl alcohol and polycarboxylic acid series polymkeric substance and the mol ratio of COOH base are 0.05-0.1; The calcium oxide that the mole number of the COOH base in polycarboxylic acid series polymkeric substance is and the mole number of silicon oxide 3.5 times.
Polycarboxylic acid series polymkeric substance be have carboxyl or anhydride group and ethene unsaturated double-bond monomer polymerization and polymkeric substance, contain carboxyl or anhydride group, and do not contain hydroxyl.
In the surperficial calcium oxide with the coating of slightly water-soluble composition and silicon oxide, the weight ratio of silicon oxide and calcium oxide is 10:1.
The slightly water-soluble composition on coated metal compound surface is the combination of fatty acid ester series organic compound or phosphoric acid ester series organic compound and calcium phosphate and aluminium hydroxide.
The weight ratio of described fatty acid ester series organic compound and calcium phosphate and aluminium hydroxide is 5:1.
The weight ratio of described phosphoric acid ester series organic compound and calcium phosphate and aluminium hydroxide is 10:1.
The invention has the beneficial effects as follows:
Gas barrier layer coating by the technical program still has than in the past high gas barrier property under high humidity, even and if also maintain excellent gas barrier property under hot and humid degree environment.
Embodiment
Describe by the following examples technical scheme of the present invention in detail, should be understood that, following embodiment is only exemplary, only can be used for explaining and technical scheme of the present invention being described, and can not to be interpreted as is the restriction to technical solution of the present invention.
Technical scheme of the present invention is applicable to polyamide membrane, for whether being applicable to other resinoid, does not specifically study, and can not determine.
A gas barrier layer coating, multipolymer, polycarboxylic acid series polymkeric substance, surface calcium oxide and the silicon oxide of slightly water-soluble composition coating that includes ethene and vinyl alcohol; OH base in the multipolymer of ethene and vinyl alcohol and polycarboxylic acid series polymkeric substance and the mol ratio of COOH base are 0.05-0.1; The calcium oxide that the mole number of the COOH base in polycarboxylic acid series polymkeric substance is and the mole number of silicon oxide 3.5 times.
Polycarboxylic acid series polymkeric substance be have carboxyl or anhydride group and ethene unsaturated double-bond monomer polymerization and polymkeric substance, contain carboxyl or anhydride group, and do not contain hydroxyl.
