Problems solved by technology

However, the existing adhesive is not stable, the kinematic viscosity of the glue drops rapidly, and the storage time is short, and it usually begins to deteriorate after about 24 hours. The root-top-shaped glue nails are formed in the center, and the backing paper and the flute peaks are effectively bonded together by glue nails
High-strength corrugated cardboard has good paper quality and high tightness. The capillary pores on the surface are blocked by sizing. Generally, the glue has poor permeability and is prone to quality problems such as false sticking, foaming, and degumming.

Abstract

The invention discloses a multi-raw material bonding agent. The multi-raw material bonding agent is prepared from the following raw materials: the multi-raw material bonding agent is characterized by comprising an A material, a B material and a C material and specifically comprising ligninsulfonate, nano-carbon, styrene, hydroxyethyl methacrylate, acrylic ester, acrylic acid, sodium persulfate, sodium allyloxy hydroxypropyl sulphonate, starch, sodium hydroxide, borax, water, ammonium dihydrogen phosphate, sodium carboxymethyl cellulose, water-soluble phenolic resin, sodium metasilicate, aluminum powder and modified wood ash. The multi-raw material bonding agent disclosed by the invention has the advantages of stable product quality, strong bonding force, good tensile force and fast drying, and can comprehensively improve various performances of a corrugated case; by adding the modified wood ash, the damages of water molecules to the bonding agent can be effectively reduced, and the water resistance of the bonding agent can be greatly improved; and as the hydrophilicity of the bonding agent is reduced, the multi-raw material bonding agent has the great fast drying property and is further conductive to being used on a high-speed corrugated paper board production linecorrugated paper board production line.

Description

technical field [0001] The present invention mainly relates to a multi-material binder, in particular to a multi-raw material binder. Background technique [0002] At present, the adhesive of corrugated cardboard in the production of tile line mainly uses starch glue adhesive. We know that the peel strength standard of the existing starch adhesive is 5.88n / m2, and its production process is one-step glue making and two-step glue making , Glue is divided into two methods of cold glue and hot glue. Practice has proved that the performance of the adhesive made by the hot glue process is better than that of the cold glue process. However, the existing adhesive is not stable, the kinematic viscosity of the glue drops rapidly, and the storage time is short, and it usually begins to deteriorate after about 24 hours. The root-top-shaped glue nails are formed in the center, and the backing paper and the flute peaks are effectively bonded together by glue nails. High-strength corruga...
