Abstract

The invention discloses a low-temperature self-crosslinked water-based acrylate resin, and a preparation method and application thereof. The low-temperature self-crosslinked water-based acrylate resin is prepared from the following components in percentage by weight: 30-50% of first monomer, 3-6% of second monomer, 1-2% of third monomer, 1-25 of fourth monomer, 40-60% of solvent, 0.6-1.2% of initiator, 60-80% of water and 4-8% of pH regulator. According to the invention, the prepared water-based acrylate resin and a water-based color paste can be compounded to finally obtain a water-based ink for printing on a low-polarity plastic film. The organic solvent content of the product is lower than 3%, and thus, the product is a safe environment-friendly water-based ink. The coated film on the plastic film has the characteristics of low-temperature self-crosslinking property (<60 DEG C), favorable staining power, high adhesive force, high glossiness and favorable adhesion resistance.

Description

technical field [0001] The invention relates to a water-based acrylate resin, in particular to a low-temperature self-crosslinking water-based acrylate resin and its preparation method and application. technical background [0002] Acrylate resin is widely used in various coatings, inks, adhesives, etc. because of its excellent adhesion, water resistance, weather resistance, and color retention. Printing inks are widely used, and basically all product packaging is inseparable from it, especially food packaging. In the past, printing inks were mostly solvent-based, containing a large amount of toxic and harmful chemical substances. These toxic substances are easy to chemically migrate and cause pollution to food and other contents. In recent years, with the continuous development of ink technology and the continuous improvement of people's awareness of environmental protection, it is imperative to develop environmentally friendly inks. At present, environmentally friendly i...
