Application Of Water-based Waterproof And Oil-proof Agents On Paper Coatings

The application of water-based waterproof and oil-proof agents on paper coatings is an environmentally friendly and effective treatment technology. It forms a thin film on the surface of paper to block the penetration of water and grease. The following is a detailed analysis of the application of water-based waterproof and oil-proof agents on paper coatings:
1. Types of water-based waterproof and oil-proof agents
This type of waterproof and oil-proof agent has the advantages of fast polymerization speed, low environmental pollution, and low preparation and use costs. Its emulsion products can be directly applied to production, which is more convenient to use. Water-based polyolefin emulsions can achieve good results at very low concentrations, and can also be mixed with other sizing agents, which is conducive to reducing costs.

2. Application effect of water-based waterproof and oil-proof agent

Excellent waterproof and oil-proof performance: Water-based waterproof and oil-proof agent can form a dense film, effectively blocking the penetration of water and grease, so that paper has excellent waterproof and oil-proof performance.

Environmental protection and safety: Water-based waterproof and oil-proof agent adopts water-based formula, does not contain harmful substances, and meets environmental protection requirements. At the same time, no organic solvents are used in its production process, which reduces pollution to the environment.

Good printing suitability: The surface of paper treated with water-based waterproof and oil-proof agent is flat and smooth, has good printing suitability, and can be applied to various printing processes.

Maintain the original performance of paper: Paper treated with water-based waterproof and oil-proof agent can maintain the original air permeability, softness, strength and color and other properties.

3. Application fields of water-based waterproof and oil-proof agents
Food packaging: Water-based waterproof and oil-proof agents can be used for coating of food packaging paper, such as hamburger paper, cake trays, etc., to effectively protect food from moisture and grease pollution.
Kitchen supplies: In terms of kitchen supplies, water-based waterproof and oil-proof agents can be used for coating of baking paper, steamer paper, etc., which is easy to clean and environmentally friendly.
Printing field: Since paper treated with water-based waterproof and oil-proof agents has good printability, it is also widely used in the printing field.

4. Application process of water-based waterproof and oil-proof agents
The application process of water-based waterproof and oil-proof agents mainly includes the selection of paper substrates, the preparation of water-based waterproof and oil-proof agents, coating processes, and drying and curing. During the coating process, it is necessary to control parameters such as coating amount, coating speed and coating uniformity to ensure the quality and effect of the coating. During the drying and curing process, it is necessary to control parameters such as temperature and time so that the coating can be fully cured and form a dense film.

In summary, the application of water-based waterproof and oil-proof agents in paper coating has broad prospects and advantages. With the continuous advancement of technology and the continuous expansion of the market, the application field of water-based waterproof and oil-proof agents will be broader, providing a more environmentally friendly, efficient and economical solution for the waterproof and oil-proof treatment of paper.
