Problems solved by technology

However, ordinary acrylate adhesives have a long production cycle, low production efficiency, and high cost. Starch has natural macromolecules, active functional groups, and outstanding characteristics that can meet environmental protection requirements. People once again shifted their attention to starch adhesives. In the past, as an environment-friendly natural adhesive, starch-based adhesives have attracted more and more attention from scholars. Starch is a kind of natural polymer material with a wide range of sources, low prices, and environmental friendliness. It is non-toxic, With the characteristics of no peculiar smell and no pollution, starch-based adhesives become one of the most potential natural adhesives
The application number is: 201610369676.7, which discloses a starch-based adhesive with strong cohesive force and good thermal conductivity for cardboard, in which lotus root starch is added to the acrylate adhesive, although it improves the overall use of the adhesive to a certain extent. characteristics, but its adhesion, water resistance, stability, etc. still cannot meet the needs, and further improvement is needed

Description

technical field [0001] The invention belongs to the technical field of adhesives, and in particular relates to a preparation method of a low-cost high-viscosity acrylate adhesive. Background technique [0002] Calcium plastic material is a new material developed by filling and modifying resin with fillers. The resins it uses are mainly thermoplastic polyolefin resins such as high-density polyethylene, low-density polyethylene or polypropylene, and the raw materials used are mainly inorganic calcium salts such as calcium carbonate, calcium sulfate or calcium sulfite, so it is called "calcium plastic". Material". Because calcium-plastic materials have the advantages of being moisture-proof and not afraid of water, good toughness and not easy to break, and are environmentally friendly and pollution-free, they can be recycled and reused. In the packaging industry, calcium-plastic materials have begun to be widely used. Calcium-plastic corrugated paper is made of calcium-plasti...
