Problems solved by technology

Although VAE emulsion can be directly used as an adhesive, its performance is not ideal, and its application is limited. It also has the following shortcomings: 1) the initial viscosity is not high enough; 2) the bonding strength needs to be improved; Improvement; 4) After the paper and the film are separated, the bonding surface is sticky, sticky to the hand, and paper dust falls off; 5) The high temperature resistance is not good

Abstract

The invention discloses a preparation method of a high-temperature-resistant paper-plastic laminating adhesive. To calculate by mass percent, the high-temperature-resistant paper-plastic laminating adhesive consists of the following components by mass percent: 60-90 of composite emulsion, 1-15 of vinyl acetate ethylene (VAE) emulsion, 1-15 of tackifying resin, 1-10 of inorganic powder filler, 1-10 of cross-linking agent, 0.2-0.5 of antifoaming agent and 0.2-0.5 of thickening agent. Firstly the composite emulsion of ethylene vinyl acetate (EVA) resin and mixed wax is prepared, then the emulsion is built up with the VAE emulsion, the antifoaming agent, the inorganic powder filler, the tackifying resin, the cross-linking agent and the thickening agent, and finally the high-temperature-resistant paper-plastic laminating adhesive is prepared. The product has the advantages of high-temperature resistance, high initial adhesive force, high peeling strength and high water resistance. After paper and plastic are separated, the bonding surface is dry, paper scraps are not stuck and an adhesive film has a transfer printing effect.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to a high-temperature-resistant paper-plastic laminating adhesive and a preparation method thereof. technical background [0002] Paper-plastic composite is the use of adhesives to combine biaxially oriented polypropylene (BOPP) or polyester (PET) films with paper prints. The composite prints are not only beautiful, but also more resistant to light, heat and water, thus greatly improving It improves the applicability and appearance of printed matter. Paper-plastic composite products can be widely used in decorative building materials, packaging materials, hardcover books, product advertisements or manuals, etc. [0003] Adhesives that can stick PP films to paper products are called paper-plastic composite adhesives, or laminating adhesives for short. Commercially available laminating adhesives include the following main products: polyurethane two-component adhesives, VAE adhesiv...
