Problems solved by technology

The existing ordinary starch glue has the following problems: (1) The degree of emulsification and viscosity of the glue are low, and the starch and heavy calcium in the glue are prone to precipitation, which affects the drying speed and the texture hardness of the finished product; ( 2) The adhesive performance is not enough, the bonding strength is not good, which affects the quality of the finished product; (3) Lack of functional additives, easy to mildew
The above-mentioned problems lead to the waste of glue in the production process, the performance of the cardboard is unstable, and even lower than the national standard

Abstract

The present invention discloses a tile mounting glue and a preparation method thereof. Raw materials of the tile mounting glue comprise, by mass, 7-9 parts of a thickener, 80-100 parts of corn starch, 5-20 parts of sodium hydroxide, 1-5 parts of borax, 1-5 parts of a defoaming agent, 1 part of a surfactant, 5-10 parts of silica sol, 5-9 parts of heavy calcium carbonate, and 80-100 parts of water, wherein the thickener is carboxymethyl cellulose and / or polyacrylic acid and / or polypropylene, the defoaming agent is tributyl phosphate or polyether-modified organosilicon, and the surfactant is sodium dodecylbenzene sulfonate or stearic acid. According to the present invention, the thickener is added so as to increase emulsification degree and viscosity of the glue material, reduce precipitation of the starch and the heavy calcium, and improve drying speed and texture hardness of the finished product; and the silica sol is added, such that adhesion strength of the starch binder is significantly enhanced, and the produced corrugated paper has characteristics of stable performance and reliable product quality.

Description

technical field [0001] The invention relates to the field of technical polymer emulsion glue, in particular to a tile-mounting glue with strong adhesive force and hard texture and a preparation method thereof. Background technique [0002] At present, the adhesives used by most domestic corrugated cardboard manufacturers are ordinary starch glue. Starch glue is widely used in the corrugated paper industry at home and abroad for its advantages of low price, simple glue making process, fast drying speed, and ability to adapt to high-speed production requirements. The existing ordinary starch glue has the following problems: (1) The degree of emulsification and viscosity of the glue are low, and the starch and heavy calcium in the glue are prone to precipitation, which affects the drying speed and the texture hardness of the finished product; ( 2) The adhesive performance is not enough, the bonding strength is not good, which affects the quality of the finished product; (3) Th...
