Abstract

The invention relates to a gelatinized starch adhesive and a preparation method thereof. The gelatinized starch adhesive is mainly composed of starch, nickel sulfate, sodium hydroxide, sodium hypochlorite, sodium thiosulfate, borax, tributyl phosphate and water. The gelatinized starch adhesive has the characteristics of low price, simple compound process, strong adhesion, good fluidity, no toxic or odor and fast drying.

Description

A kind of pasting starch adhesive and preparation method thereof

Technical field

The present invention relates to a kind of pasting starch adhesive and preparation method thereof, belonged to composite modified starch technical field.

Background technology

General pasting starch adhesive is to export at present the tackiness agent that carton goods packaging industry is generally applied, but due to it, exist the indices such as bond strength, storage period, environmental protection undesirable, preparation method is loaded down with trivial details, high to environment temperature, humidity requirement in preparation, need thermostatic constant wet equipment preparation, and the shortcoming such as preparation time, cycle be long.

The present invention has determined a kind of brand-new formula, has both met production required, has improved again production efficiency.

Summary of the invention

Object of the present invention be exactly for existing general pasting starch adhesive, exist to defects such as the indices such as bond strength, storage period, environmental protection in carton making process are undesirable, provide a kind of and have that price is low, recombining process is simple, bonding force is strong, good fluidity, nonpoisonous and tasteless, pasting starch adhesive of the feature such as rate of drying is fast and preparation method thereof.

The present invention is achieved through the following technical solutions, it is characterized in that this pasting starch adhesive mainly by: starch, single nickel salt, sodium hydroxide, clorox, Sulfothiorine, borax, tributyl phosphate, water etc. form.

, this pasting starch adhesive by its weight percent is: starch 15～25%; Single nickel salt 0.1～0.2%; Sodium hydroxide 1～5%; Clorox 6～10%; Sulfothiorine 0.1～0.2%; Borax 0.5～1.0%; Tributyl phosphate 1.0～2.0%; Water 100～150% compositions such as grade.

, its starch is a kind of of W-Gum or wheat starch.

, its preparation method is:

First water stirs 10min together with starch, makes it swelling, then adds nickel sulfate solution (by preparation in 1: 0.04) to stir 10mi n, add again sodium hydroxide, stir 15min, then add borax, after stirring 10mi n, add tributyl phosphate, stir 10min.

Embodiment

1 accurately takes starch 20% by its weight percent; Single nickel salt 0.1%; Sodium hydroxide 3%; Clorox 8%; Sulfothiorine 0.1%; Borax 0.8%; Tributyl phosphate 1.0%, standby.

2 preparation methods

First water stirs 10min together with starch, makes it swelling, then adds nickel sulfate solution (by preparation in 1: 0.04) to stir 10mi n, add again sodium hydroxide, stir 15mi n, then add borax, after stirring 10min, add tributyl phosphate, stir 10min.

Claims
