Embodiment 1

[0020] The present embodiment one provides a kind of production method of biopolymer oil-proof translucent paper, comprises the following steps:

[0021] In the first step, after the translucent base paper is made, the first oil-proof coating is coated, and then calendered. The first oil-proof coating includes the following materials by weight for preparation: 50 parts of starch, 20 parts of chitosan , 2 parts of carboxymethyl cellulose, 5 parts of polyvinyl alcohol, 10 parts of montmorillonite nanopowder;

[0022] The second step is heat preservation and setting, the heat preservation temperature is 50-70 ℃, the heat preservation time is 0.6-1 hour, and then calendering;

[0023] The third step is to coat the second oil-proof coating, the second oil-proof coating includes the following materials in parts by weight for preparation: 40 parts of Atractylodes stearin, 20 parts of Artemisia argyi extract, 5 parts of gum arabic, and the Artemisia argyi extract is passed through the...

Abstract

The invention relates to a production method of biological polymer oil-proof translucent paper. The production method comprises the following steps: (1) after translucent raw paper is produced, coating the translucent raw paper with a first oil-proof coating, and then carrying out calendering, wherein the first oil-proof coating is prepared from the following raw materials in parts by weight: 50-80 parts of starch, 20-40 parts of chitosan, 2-5 parts of carboxymethylcellulose, 5-10 parts of polyvinyl alcohol and 10-15 parts of montmorillonite nano-powder; (2) carrying out thermal formation at 50-70 DEG C for 0.6-1 hour, and carrying out calendering; (3) coating the translucent raw paper with a second oil-proof coating; (4) carrying out thermal insulation formation at 50-70 DEG C for 0.6-1 hour; (5) after the thermal insulation, carrying out calendering; and (6) carrying out hot-wind drying at 80-90 DEG C. According to the production method, the technical problems that existing oil-prooftranslucent paper has a common antibacterial effect and is relatively high in toxicity and difficult to degrade are solved.

Description

technical field [0001] The invention relates to a production method of biopolymer oil-proof translucent paper. Background technique [0002] At present, Chinese Patent No.: CN201510539518.7 discloses a production method of oil-proof paper, which includes the following steps: the first step is to apply the first oil-proof coating layer on the base paper by horizontal coating; the second step is to When the dryness of the first oil-repellent paint layer reaches between 25% and 35%, the second oil-repellent paint layer is coated on the base paper by vertical coating; the third step is to coat the second oil-repellent paint layer At the same time, the wood pulp-based cellulose material particles are evenly sprayed on the area of ​​the second oil-proof coating layer; the fourth step, after the spraying is completed, heat preservation treatment is carried out, the heat preservation temperature is 45-55 °C, and the heat preservation time is 10 to 30 minutes; the fifth step, after ...
