Description

Degradable composite barrier coating applied to film-based material and production equipment thereof
Technical Field
The invention relates to the technical field of degradable coatings, in particular to a degradable composite barrier coating applied to a film-based material and production equipment thereof.
Background
In the past, with the implementation of plastic-limiting command and the continuous improvement of environmental awareness of people, the food packaging industry has begun to use paper-based materials such as paper and paperboard to replace synthetic polymers in a large number. However, as with conventional polymeric packaging materials, paper-based packaging also needs to have high strength, high barrier functionality. For food packaging, atmospheric water vapor and oxygen are critical to the ability to penetrate the packaging material and spoil the food. In order to avoid the influence of oxygen and moisture transfer on the quality of food, to improve the shelf life of food, good gas barrier properties and liquid permeation resistance are of great importance for food packaging materials, which are also the most interesting properties for researchers. Due to the characteristics of cellulose materials, on the one hand, cellulose is highly hydrophilic and on the other hand, fibers are interwoven to form a porous network structure, so that paper and paperboard materials generally have very strong liquid absorption and air permeability, which greatly limit the use of paper-based materials in the field of direct food packaging.
At present, the method for improving the barrier property of the paper-based package mainly comprises the following steps:
(1) dipping oils, waxes, resins, latex, and the like;
(2) depositing a dense oxide film on the surface;
(3) compounding plastic with paper to prepare a paper-plastic composite material;
(4) the surface is coated with a synthetic or natural polymer.
The first 3 methods are widely used and have remarkable effects, but most of the materials used are not degradable, and the recycling and repulping of paper products are difficult and not environment-friendly. The surface coating method has simple process and easy production, and particularly, the use of degradable polymers as coating materials is the main development direction at present. Degradable materials are a type of degradable polymer coating materials which can be decomposed into small molecular polymers from large molecular polymers through internal melting of polymers caused by external actions (light, heat, microorganisms and mechanical actions), and common degradable polymer coating materials include nanocellulose, polyhydroxybutyrate (PHB), polylactic acid (PLA), polyvinyl alcohol (PVA) and the like.
In China, the paint is divided into powder paint and liquid paint, the powder paint can be mixed with water or other mixed solvents to prepare liquid paint, the liquid paint is generally paint, the paint is mainly resin, oil or emulsion, pigment and filler are added or not added, corresponding auxiliary agents are added, and the viscous liquid prepared by using organic solvents or water is required to be ground in production, and large particles are ground into fine particles, so that the quality of the paint is improved.
The current production equipment has certain disadvantages:
1. when larger particle powder is ground, only a simple grinding process can be performed, and when multiple grinding is needed, the device is required to grind in different grinding equipment, so that unnecessary troubles are increased, a certain amount of paint is lost, and time and efficiency are delayed.
2. In addition, when the paint is incompletely ground, rapid separation cannot be performed, the ground paint needs to be sorted again, and the incompletely ground large particles need to be ground again, so that screening cannot be performed simultaneously during grinding, and efficiency is reduced.
3. When screening, the coating is screened through the screen cloth, but the coating falls on the screen cloth and is still in a standing state, so that the efficiency of the coating screen cloth is low, and simultaneously, the coating is easy to block the aperture of the screen cloth, so that the screening speed of the screen cloth is further slowed down, and the screen cloth is gradually blocked.
