Description

Degradable oil type oilproof paper
Technical Field
The invention relates to the technical field of oil-proof paper, in particular to degradable oil-type oil-proof paper.
Background
The oil-proof paper is special paper capable of preventing oil and fat from permeating, and is generally manufactured by high-beating-degree treatment; at present, more functional varieties which are produced by adding oil-proof agents into pulp or coating oil-proof agents on the surfaces of the pulp and can resist the penetration and absorption of grease are widely applied to food manufacturing and packaging.
If oil or fat components contained in the food permeate into the packaging material, the oil permeates to the surface not in contact with the food to form oil stains, thereby impairing the appearance and lowering the commercial value; or the printed part becomes black due to oil stain and the characters can not be recognized; or the OCR adaptability to generate a barcode or the like is degraded. Further, there is a problem that oil is transferred to clothes to become dirty, and thus, the above problem can be solved by using an oil-repellent paper for a portion in contact with food.
At present, most of the oil-proof papers produced at home and abroad use fluorochemicals as oil proofing agents to treat the surface of paper, and for example, patent document CN 200780033946.6 discloses an oil-proof paper which uses fluorochemicals to coat or size paper to achieve oil-proof effect. The high-carbon-chain fluorine-containing compound also has the problem of environmental protection, the main component preparation raw material and the intermediate perfluorooctane sulfonyl compound have high durability and biological accumulation in the environment, can be widely accumulated in the environments of blood, seawater and the like of people and animals to cause damage to the animals, has larger usage amount and higher cost, and can cause the biodegradation of oil-proof paper, thereby bringing hidden troubles to the food safety and the environmental problems.
U.S. Pat. No. 4, 7019054, 2, which discloses a fluorine-free coating formulation for in-machine sizing, is used for coating paper to improve the oil-proof performance of the paper and has a good oil-proof effect similar to fluorocarbon-treated paper; and the quantitative rate is low, and the method is relatively environment-friendly. Japanese patent application laid-open No. 2004-68180 discloses an oilproof paper coated with a polyvinyl alcohol or a coating agent comprising a polyvinyl alcohol and a crosslinking agent in combination. Since the polyvinyl alcohol polymer is a water-soluble polymer, there is a possibility that water absorption is increased. Therefore, when a food containing moisture, such as a fried food, a food which needs to be steamed or heated by microwaves, is packaged, the moisture vapor emitted from the food fills the inside of the packaging bag, and the outer layer of the fried food or the like contains moisture and becomes too soft, resulting in a noticeable deterioration in taste or stickiness on the paper surface.
Jp 2001-214396 a discloses that a paper composite having a layer of a resin composition containing a saponified ethylene-vinyl acetate copolymer and a layered inorganic compound has relatively improved liquid barrier properties and water resistance, but has insufficient oil resistance under high-temperature conditions.
US2008/0171213a1 proposes a method for improving the oil repellency of an oil repellent paper by changing the number of coating layers when the coating amount is constant: the surface of the paper is precoated with a base coat, the main component of the base coat is a starch derivative (the amylose content is more than 70%) modified by C2-C6 alkylene oxide, and meanwhile, glycerin, borax, urea and the like can be added into the coating, so that the oil-proof performance is improved by increasing the elasticity of the coating.
Disclosure of Invention
Aiming at the defects that most of the oil-proof paper in the prior art contains fluorine-containing compounds, is high in cost and cannot be degraded, and is easy to affect the environment, and the non-fluorine-containing materials cannot absorb the grease in food, the invention provides the degradable oil-proof paper by researching and designing a hydrophobic oil storage layer.
In order to solve the technical problem, the invention is solved by the following technical scheme:
the degradable oil-type oil-proof paper includes base paper, hydrophobic oil storing layer on the base paper, composite film layer comprising hydrophobic oil storing particle and composite resin, the hydrophobic oil storing particle is formed by coupling and modifying laminated inorganic matter and one or two of fatty acid, fatty acid salt and fatty acid ester with coupling agent, and the composite resin is formed by two kinds of composition of chitosan, carboxymethyl cellulose, sodium alginate and cationic starch and polyvinyl alcohol-microcrystalline cellulose.
The hydrophobic oil storage particles are pompon-shaped particles which are formed by modifying a layered inorganic substance and one or two of fatty acid, fatty acid salt and fatty acid ester through silane coupling and have hydrophobic long chains on the surfaces, the hydrophobic long chains are carbon chains of the fatty acid, the fatty acid salt and the fatty acid ester, and the hydrophobic long chains can increase the binding force between the hydrophobic oil storage particles and oil and the oil absorption capacity, so that the oil permeates into the pompon-shaped hydrophobic oil storage particles through the hydrophobic long chains and then is stored in the hydrophobic oil storage particles to achieve the oil absorption effect.
The composite resin is formed by two compositions of chitosan, carboxymethyl cellulose, sodium alginate and cationic starch and polyvinyl alcohol-microcrystalline cellulose, and the biodegradable material used by the composite resin has hydrophilicity for obstructing the diffusion of grease, so that the oil-proof effect can be achieved.
Preferably, the hydrophobic oil reservoir layer comprises the following components in percentage by mass:
15 to 45 percent of composite resin
55 to 85 percent of hydrophobic oil storage particles.
Preferably, the content of each component in the hydrophobic oil storage particles is as follows by mass percent:
61 to 91 percent of layered inorganic substance
9 to 39 percent of one or two of fatty acid, fatty acid salt and fatty acid ester.
Preferably, the layered inorganic matters are two of talcum powder, high clay and light calcium carbonate, and gaps in the layered inorganic matters can provide storage space for the oil, so that the hydrophobic oil storage particles can store the oil, and the oil absorption effect is achieved.
Preferably, the fatty acid, fatty acid salt and fatty acid ester have 8 to 22 carbon atoms in the carbon chain.
More preferably, the carbon chain of the fatty acid, fatty acid salt or fatty acid ester has 12 to 18 carbon atoms.
Generally, the oil in the food is mainly C18 fatty glyceride, when the carbon chain of the fatty acid, the fatty acid salt and the fatty acid ester has the carbon atom number of 12-18, the length of the carbon chain of the invention is closer to that of the oil carbon chain, and therefore, the polarity of the carbon chain of the invention and the oil carbon chain is also closer, so that the carbon chain of the invention, namely the hydrophobic long chain has better binding force with the oil, and the oil absorption capacity of the hydrophobic long chain is further improved.
Preferably, the thickness of the hydrophobic oil storage layer is 2-8 mu m, at the moment, the oil absorption and oil prevention effects of the hydrophobic oil storage layer are good, and oil cannot penetrate through the base paper and permeate into the surface of food. When the thickness of the hydrophobic oil storage layer is less than 2 mu m, the oil absorption and prevention effects of the hydrophobic oil storage layer are poor, and oil easily permeates through the base paper to permeate into the surface of food, so that the taste and appearance of the food are influenced; when the thickness of the hydrophobic oil reservoir is more than 8 μm, the oil absorption and prevention effects of the hydrophobic oil reservoir are good, but the production and material costs are increased.
Preferably, the particle size of the hydrophobic oil storage particles is 1-3 μm, and in this case, the hydrophobic oil storage particles can store a proper amount of oil and fat and can be used for packaging high-oil fried foods and the like.
Preferably, the mass of the hydrophobic oil storage layer on each square meter of the base paper is 0.3-7.0 g, at the moment, the hydrophobic oil storage particles can store a proper amount of grease, the grease is prevented from entering the base paper, the oil absorption and prevention effects of the grease-proof paper are realized, and the grease-proof paper can be used for packaging high-grease fried foods and the like. When the mass of the hydrophobic oil storage layer on each square meter of the base paper is less than 0.3g, the oil-proof paper has poor oil absorption and oil resistance effects, and is not suitable for packaging high-oil fried foods and the like. When the mass of the hydrophobic oil storage layer on each square meter of the base paper is more than 7.0g, the oil absorption and prevention effects of the oil-proof paper are better, but the production and material costs are increased.
Preferably, the mass of the hydrophobic oil storage layer on each square meter of the base paper is 0.5-4.0 g, at the moment, the hydrophobic oil storage particles can store a proper amount of oil, so that the oil is prevented from entering the base paper, and the oil absorption and prevention effects of the oil-proof paper are realized, therefore, the condition can save materials and production cost, and can also be used for packaging high-oil fried foods and the like.
Due to the adoption of the technical scheme, the invention has the remarkable technical effects that:
the oil-proof paper absorbs grease by arranging the hydrophobic oil storage layer, and hydrophobic oil storage particles are arranged in the hydrophobic oil storage layer. The hydrophobic oil storage particles are pompon-shaped particles which are formed by coupling and modifying a layered inorganic substance and one or two of fatty acid, fatty acid salt and fatty acid ester through a silane coupling agent, the surface of the pompon-shaped particles is provided with a hydrophobic long chain, the hydrophobic long chain is a carbon chain of the fatty acid, the fatty acid salt and the fatty acid ester, and the hydrophobic long chain can increase the binding force between the hydrophobic oil storage particles and oil and the oil absorption capacity, so that the oil permeates into the pompon-shaped hydrophobic oil storage particles through the hydrophobic long chain and then is stored in the hydrophobic oil storage particles to achieve the oil absorption effect.
The composite resin is formed by two compositions of chitosan, carboxymethyl cellulose, sodium alginate and cationic starch and polyvinyl alcohol-microcrystalline cellulose, and the biodegradable material used by the composite resin has hydrophilicity and can block the diffusion and permeation of grease, so that the oil-proof effect is achieved.
Therefore, the oil-proof package has the characteristics of obvious oil absorption, oil diffusion resistance and degradability, has good oil-proof effect, and can be used for packaging high-oil fried food and the like.
