Problems solved by technology

At present, coated polyethylene (PE) is mainly used as a waterproof and oil-repellent agent, but the PE sprayed on the surface of the paper material is very difficult to separate from the paper material, so that the paper tableware can only be disposed of by landfill or incineration, which cannot be fully processed. Taking advantage of the environmental advantages of paper materials that can be recycled and repulped, more environmentally friendly materials that can replace coated PE have become a research hotspot in the industry

Abstract

The invention discloses a waterproof and oil-proof agent. The waterproof and oil-proof agent comprises thermoplastic waterproof and oil-proof acrylic resin and thermoplastic reinforced acrylic resin, the thermoplastic waterproof and oil-proof acrylic resin contains a waterproof monomer and an oil-proof monomer; the waterproof monomer comprises an acrylate monomer and a styrene monomer; the oil-proof monomer is an acrylate monomer containing at least one of hydroxyl, amino and carboxyl; and the thermoplastic reinforced acrylic resin contains a self-crosslinking group. According to the waterproof and oil-proof agent, domestic acrylic resin is adopted, the cost is lower, two kinds of acrylic resin with different functions are adopted, the double-acrylic resin is scientifically compounded, a coating can be endowed with waterproof, oil-proof, temperature-resistant, non-sticky and peelable functions, when the waterproof and oil-proof agent is applied to paper-based packaging, a paper base can be re-pulped and recycled, and the adopted acrylic resin has heat sealability, so that the paper material of which the surface is coated with the waterproof and oil-proof agent can be directly heat-sealed and molded into various paper-based packages, and the paper material does not contain fluorine, and is non-toxic and odorless.

Description

technical field [0001] The invention relates to a waterproof and oil-repellent agent, in particular to a waterproof and oil-repellent agent for various waterproof and oil-proof paper-based packages (including but not limited to disposable paper-based containers for catering and food packaging) and its preparation for waterproofing Applications in greaseproof paper-based packaging. Background technique [0002] Since the invention of plastics, plastic products have been used more and more widely, bringing great convenience to our daily life, especially in the catering industry. At the same time, the problem of plastic pollution caused by plastic products has become increasingly serious and has become a hot environmental issue that is widely concerned by countries all over the world. [0003] In recent years, countries around the world have also introduced a number of related policies for plastic pollution control. On January 1, 2020, the official implementation of the Frenc...
