Abstract

The invention relates to the field of adhesives and in particular relates to a rapid-drying starch adhesive. The rapid-drying starch adhesive is characterized by comprising the components in parts by weight: 12 parts of corn starch, 80 parts of water, 6-10 parts of sodium hypochlorite, 2-3 parts of sodium hydroxide, 2-3 parts of di-tert-butyl ether peroxide, 1-2 parts of ferrous sulfate, 200-230 parts of formaldehyde, 100 parts of urea and 1-2 parts of citric acid. Compared with the prior art, the rapid-drying starch adhesive is low in the permeability, rapid in the drying speed and high in the production efficiency; according to the rapid-drying starch adhesive, adhered corrugated paper is firm and smooth, is difficultly stripped without exposing arris, cannot be moistened due to water absorption and is particularly suitable for storing goods in the moist environment.

Description

A kind of rapid-drying starch adhesive

Technical field

The present invention relates to adhesive area, relate in particular to a kind of rapid-drying starch adhesive.

Background technology

For many years, the conventional water glass of China's fluting board is as tackiness agent.But because the sodium hydrate content in water glass is high, alkalescence is large, easily absorbs moisture, causes that carton makes moist, and even corrodes article in case.Adopt afterwards amylan to replace water glass, and because amylan can not absorb moisture, be not easy to make moist, be suitable as the tackiness agent of Corrugated Box.But the time of drying of common amylan is longer, the moisture in amylan easily infiltrates Corrugated Box inside, affects the quality of Corrugated Box, has increased production difficulty and cost.

Summary of the invention

The object of the present invention is to provide a kind of rapid-drying starch adhesive, the defect existing to solve prior art.

In order to realize above-mentioned object, adopt following technical scheme: a kind of rapid-drying starch adhesive, comprises following component and weight part:

W-Gum 12;

Water 80;

Clorox 6-10;

Sodium hydroxide 2-3;

Peroxidation di-t-butyl 2-3;

Ferrous sulfate 1-2;

Formaldehyde 200-230;

Urea 100;

Citric acid 1-2.

Compared with prior art, perviousness of the present invention is low, and rate of drying is fast, and production efficiency is high, bonding fluting board firm smooth, be difficult for peeling off, do not reveal stupefied, can not absorb water and make moist, be particluarly suitable for hoarding of money under wet environment.

Embodiment

Below in conjunction with embodiment, the invention will be further described.

Embodiment the present invention includes following component and weight part: W-Gum 12g; Water 80g; Clorox 8g; Sodium hydroxide 3g; Peroxidation di-t-butyl 2g; Ferrous sulfate 1g; Formaldehyde 200g; Urea 100g; Citric acid 1g.Preparation process comprises the following steps: (1) will be less than 150 object W-Gums and be poured into water and stir into paste, be heated to 50 ℃, add clorox and stir 20 minutes, then add half sodium hydroxide solution and stir 10 minutes, add again peroxidation di-t-butyl and stir 5 minutes, finally add ferrous sulfate, stir standby; (2) by formaldehyde and remaining sodium hydroxide solution mix and blend, be heated to 50 ℃ and add half urea, be warming up to 80 ℃ of reactions 80 minutes, be warming up to again 90 ℃, add remaining urea and react 20 minutes, then adding citric acid, carrying out vacuum hydro-extraction after being incubated standing 2 hours; (3) mixing of materials step (1) (2) being made stirs 1 hour, and discharging obtains finished product.
