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.

Embodiment 1

[0019] An ester binder is characterized in that it is composed of three materials A, B and C:

[0020] The material A is composed of the following raw materials in parts by weight: lignosulfonate 2, modified wood ash 2, styrene, hydroxyethyl methacrylate 2, acrylate 2, acrylic acid 10, sodium persulfate 2 , Sodium Allyloxy Hydroxypropyl Sulfonate 2,

[0021] The preparation method of described modified tree ash is:

[0022] (1) Tree ashes were soaked in 15% hydrogen peroxide for 4 hours, washed with deionized water, then soaked in 12% sodium hydroxide solution for 4 hours, washed with deionized water until neutral, and dried;

[0023] (2) Add 3% sodium lauryl sulfate, 2% nano-carbon, 3% polyisobutylene, and 5% alum powder to the tree ashes, stir at a high speed of 1500 rpm, dry and pulverize into super fine powder;

[0024] The B material is composed of the following raw materials in parts by weight: starch 20, sodium hydroxide 2, borax 1, water 30;

[0025] The C material...

Abstract

The invention discloses an esters binder. The binder is prepared from the following raw materials: lignosulfonate, modified wood ash, styrene, hydroxyethyl methacrylate, acrylate, acrylic acid, sodium persulfate, 3-allyloxy-2-hydroxy propane sulfonic acid, starch, sodium hydroxide, borax, water 30, water glass, ammonium polyphosphate, pure acrylic emulsion, aluminum hydroxide, and sodium lauryl ether sulfate. The binder disclosed by the invention is stable in product quality, strong in binding force, good in stiffness, fast cured without foaming, and capable of comprehensively improving various performances of a corrugated case; by adding the modified wood ash, the destruction of the binder due to a water molecule can be effectively reduced, so that water resistance of the binder is greatly improved; and as the hydrophilic performance of the binder is reduced, the binder has the characteristic of fast drying so as to facilitate application to a high-speed tile line.

Description

technical field [0001] The present invention mainly relates to an adhesive, in particular to an ester adhesive. 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 corrugated cardboard has ...
