preparation example 1

[0054] Surface treatment of inorganic fillers:

[0055] 1. Use an ion implanter to perform ion implantation on calcium carbonate of model JKGX-A1. The acceleration voltage is 50Kv. The accelerated ion beam passes through the magnetic analyzer of the ion implanter. The ion selected by the magnetic analyzer from the ion beam bombards the calcium carbonate Calcium target surface; then the calcium carbonate obtained through the above operations is mixed with Silquest A-187 silane coupling agent for surface modification to obtain modified calcium carbonate.

[0056] 2. The 4A molecular sieve is screened by ball milling to obtain 4A molecular sieve powder with a particle size of 4 μm. The ion implanter is used to implant 4A molecular sieve powder with an accelerating voltage of 50Kv. The accelerated ion beam passes through the magnetic analyzer of the ion implanter. The ions selected by the analyzer from the ion beam bombard the target surface of the 4A molecular sieve powder; then ...

Abstract

The invention relates to the technical field of packaging films, particularly to a visible antibacterial breathable anti-fog film and a preparation method thereof. The visible antibacterial breathableanti-fog film comprises a visible film and an antibacterial breathable anti-fog film, wherein the antibacterial breathable anti-fog film is prepared from the following raw materials in parts by weight: 80-90 parts of breathable master batch, 5-10 parts of antibacterial master batch and 5-10 parts of anti-fog master batch. The product has the advantages that consumers can visually see contents, and the product has multiple properties of antibiosis, fresh keeping, antifogging and modified atmosphere. The preparation method comprises the following steps: weighing the breathable master batch, theantibacterial master batch and the anti-fog master batch in proportion, and blending; extruding, wherein the temperature of the charging section and the homogenizing section is 170-220 DEG C, and thetemperature of the die head is 200-230 DEG C; casting, wherein the temperature of a cooling roller is 25-30 DEG C; stretching, wherein the stretching ratio of the film is 1.05-1.30; and carrying outheat setting to obtain a target product, wherein the heat setting temperature is 80 DEG C after the film is stretched. The method has the effects of simplicity in operation and convenience in industrial production.

Description

technical field [0001] The present application relates to the technical field of packaging films, in particular to a visible antibacterial breathable anti-fog film and a preparation method thereof. Background technique [0002] Anti-fog and anti-bacterial packaging plays an important role in the quality of modern food, especially fresh food. Most fresh foods are perishable, seasonal and regional. In addition, post-production storage and fresh-keeping technologies are relatively lagging behind, which can easily lead to spoilage of fresh foods. In addition, the moisture content of fresh food is very high. Traditional packaging materials may produce water vapor due to changes in the external environment temperature or the respiration of fruits and vegetables. This situation will cause fogging on the inner surface of the packaging, which will not only affect the quality of the food, but also easily cause food spoilage. spoiled. Therefore, anti-fog and antibacterial packaging m...
