Abstract

The invention provides a polyacrylate adhesive for calcium plastic corrugated paper and a preparation method thereof. The adhesive comprises 3-5% of N-hydroxymethyl acrylamide, 20-30% of soft monomer, 5-8% of hard monomer, 0.45-0.7% of emulsifier, 1.5-2% of ammonium persulfate, 1-6% of PVB (polyvinyl butyral), 7-10% of 95% ethanol, 7-10% of ethyl acetate and the balance of water. The preparation method comprises the following steps: adding the emulsifier, 1 / 2 of N-hydroxymethyl acrylamide, 1 / 2 of soft monomer and 1 / 2 of hard monomer into a four-neck flask; adding 1 / 3 of ammonium persulfate and water; dropwisely adding the rest of N-hydroxymethyl acrylamide, soft monomer, hard monomer and ammonium persulfate, keeping at the temperature of 85 DEG C for 2 hours, and cooling to 50 DEG C; regulating the pH value to 6-7 to obtain an acrylate adhesive; and adding the PVB into the 95% ethanol to obtain a white transparent colloid, adding the ethyl acetate, adding the acrylate adhesive, and heating while stirring, thereby obtaining the finished product. The adhesive has the advantages of high adhesive strength, high tensile strength and low cost.

Description

technical field [0001] The invention relates to the technical field of adhesives and preparation thereof, in particular to a polyacrylate adhesive for calcium-plastic corrugated paper and a preparation method thereof. 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 corr...
