specific Embodiment 1

[0012] The parts by weight are respectively 10 parts of sodium alginate (C6H7O8Na)n, 5 parts of competing hydrate-sodium chloride, 20 parts of water-soluble glue-white latex, and 65 parts of water. Stir and mix evenly at normal temperature and pressure, and then spray Get the glued side on the self-adhesive paper. Due to the low solute content, the obtained adhesive surface can be made ultra-thin after it is completely dried, the adhesive surface is stable, and the viscosity is relatively low. When it is removed, it is not easy to remain on the solid surface.

specific Embodiment 2

[0013] The parts by weight are 20 parts of sodium alginate (C6H7O8Na)n, 8 parts of competing hydrate-sodium chloride, 35 parts of water-soluble glue-white latex, and 37 parts of water. Stir and mix evenly at normal temperature and pressure, and then spray. Get the glued side on the self-adhesive paper. After the adhesive is made into a rubber surface and completely dried, it is suitable for the production and manufacture of ordinary self-adhesives. It has a high viscosity in water and a high lubricity of the rubber surface.

specific Embodiment 3

[0014] The parts by weight are respectively 35 parts of sodium alginate (C6H7O8Na)n, 10 parts of competing hydrate-sodium chloride, 50 parts of water-soluble glue-white latex, and 5 parts of water. Get the glued side on the gummed paper. The adhesive has a high viscosity and a high expansion rate, so it is not suitable for making self-adhesives and can be used as special adhesives.

Abstract

The invention provides a method for preparing hydrated adhesive, which solves the problems of disposable usage, difficultly-controlled pasting position, difficult removal and the like in the traditional tackifier fundamentally. The technical key points of the invention are as follows: the hydrated adhesive is prepared by mixedly stirring the following raw materials by weight percent at normal temperature and pressure: 10%-35% of sodium alga acid (C6H7O8Na), 5%-30% of competed hydrate, 20%-50% of water-soluble adhesive and 5%-65% of water. The hydrated adhesive in the invention has the advantages of controllable viscosity, stable physicochemical property, environment protection, capability of repeated use, no residual and the like, and is suitable for caking of solid materials such as various paper, plastic and the like.

Description

technical field [0001] The invention relates to a method for preparing a self-adhesive surface and a water-based adhesive, in particular to a method for preparing a hydration adhesive suitable for bonding any solid materials such as paper and plastic. Background technique [0002] The main materials of traditional adhesives are natural (synthetic) rubber and acrylic. Applications were filed in the United Kingdom and the United States on May 30, 1928. Drew developed a very light, one-press adhesive, which was later improved Scotch tape was invented again, that is, a layer of adhesive is coated on the surface of the tape. The earliest adhesives came from animals and plants. In the 19th century, rubber was the main component of adhesives, but in modern times, various polymers are widely used. Adhesives can stick to things because of the formation of bonds between their own molecules and the molecules of the objects to be connected, and this bond can firmly bind the molecules t...
