Special CN201210272313.3 (Gao Xiaoming. A production process of oil-proof paper: China, CN201210272313.3 [P].2012-11-7) discloses a production process of oil-proof paper. The safety hazards that may be brought about by the extensive use of oil-repellents in oil-proof paper greatly reduce the amount of oil-repellents used, but wax emulsions need to be added in this process, which reduces the degradation performance of paper, and the papermaking process is more complicated

preparation example Construction

[0020] The preparation method of greaseproof paper 110 of the present invention, its steps are as follows:

[0021] (1) Provide the initial base paper 100 .

[0022] (2) Preparation of composite oil-proof coating

[0023] Using starch, plasticizer, coalescent, fluoropolymer and water, the temperature of the water bath heated in the water bath is 70-95°C

[0024] The starch and the film-forming aid are dissolved under the condition of 5-30 minutes, and the starch, the plasticizer, the film-forming aid, the fluorine-containing compound and water are mixed under the condition of stirring for 5-30 minutes to prepare a composite oil-proof coating.

[0025] (3) Coating a composite oil-repellent coating on the surface of the base paper 100 and drying it with hot air at a drying temperature of 70-105° C. to form an oil-repellent coating 101 . A coating machine is used to apply the composite oil-repellent coating to the surface of the base paper 100 . After drying, the moisture in t...

example 1

[0030] Base paper 100 is made of transparent paper with a basis weight of 20 g / m 2 .

[0031] Composite oil-proof coating: 100 parts of starch, 10 parts of plasticizer, 100 parts of film-forming aid, 20 parts of fluorine-containing compound. The starch is natural starch. Described plasticizer is glycerol. The film-forming aid is polyvinyl alcohol. The fluorine-containing compound is perfluoropolyether phosphate, and the solid content of the coating is 5%.

[0032] Dissolve starch and film-forming aids under the condition that the water bath temperature of the water bath is 70°C, and then mix the starch, plasticizer, film-forming aids, fluorine-containing compounds and water at a speed of 80 r / min. Stir for 5 minutes to prepare a composite oil-proof coating.

[0033] Use a composite oil-repellent coating to form an oil-repellent coating on the surface of base paper 100 by roll coating, with a coating weight of 9.5 g / m 2 , and use hot air to dry at a drying temperature of ...

example 2

[0036] The base paper 100 is translucent paper with a basis weight of 32 g / m 2 .

[0037] Composite oil-proof coating: 100 parts of starch, 40 parts of plasticizer, 50 parts of film-forming aid, 30 parts of fluorine-containing compound. The starch is modified starch. Described plasticizer is sorbitol. The film-forming aid is cellulose. The fluorine-containing compound is perfluoropolyether phosphate, and the solid content of the paint is 15%.

[0038] Dissolve the starch and film-forming aids under the condition that the temperature of the water bath heated by the water bath is 95°C, and then mix the starch, plasticizer, film-forming aids, fluorine-containing compounds and water at a speed of 200 r / min. Stir for 30 minutes to prepare a composite oil-proof coating.

[0039] Use a composite oil-repellent coating to form an oil-repellent coating on the surface of base paper 100 by roll coating, with a coating weight of 1 g / m 2 , and dried with hot air at a drying temperatur...

Abstract

The invention discloses oil-proof paper and a production method thereof, and belongs to the technical field of oil-proof paper. The production method comprises the following steps: coating or sizing the base paper with composite oil-proof paint; and drying to obtain the finished paper, wherein the composite oil-proof paint comprises the following components in parts by weight: 100 parts of starch, 10-40 parts of a plasticizer, 5-100 parts of a coalescing agent and 1-30 parts of a fluorine-containing compound; the solid content of the paint is 5-15%. The composite oil-proof paint comprises the starch, the plasticizer, the coalescing agent and the fluorine-containing compound. The oil-proof paper disclosed by the invention has the advantages of relatively low cost and excellent oil-proof property.

Description

technical field [0001] The invention belongs to the technical field of greaseproof paper, in particular to a production method of greaseproof paper. technical background [0002] At present, as the application fields of paper become more and more extensive, many applications require paper to have a certain oil resistance, such as various food packaging paper, outer packaging cardboard, release paper, carbonless copy paper and various art papers. Research and development of new and efficient greaseproof paper will become the mainstream of the development of greaseproof paper field. [0003] At present, the oil-proof paper sold in the market is basically coated with fluoropolymer on the surface of the paper, but the use of fluoropolymer is large, the cost is high, and the fluoropolymer with high carbon chain has environmental problems. Special CN201210272313.3 (Gao Xiaoming. A production process of oil-proof paper: China, CN201210272313.3 [P].2012-11-7) discloses a productio...
