Embodiment 1

[0016] Example 1: Mix 40kg of modified starch with a particle size of 100 mesh and 50kg of water, add 0.4kg of potassium permanganate oxidizing agent in turn, fully react at room temperature to gelatinize the starch, and add 0.18kg of vinyl acetate emulsion after 100 minutes to terminate Then carry out solid-liquid separation, after the separation, add water to make the emulsion concentration reach 38%, add 6.5kg vinyl acetate synthesis agent, 0.4kg sodium hydroxide catalyst, 0.05kg alum, react for 4 hours, and the pH value is above 7 , and then carry out solid-liquid separation, washing, drying, packaging and storage.

Embodiment 2

[0017] Example 2: Get 55kg of modified starch with a particle size of 100 mesh and 50kg of water, add 0.45kg of potassium permanganate oxidizing agent in turn, fully react at room temperature to gelatinize the starch, add 0.25kg of vinyl acetate emulsion after 100 minutes to terminate Then carry out solid-liquid separation, after separation finishes, add water, make emulsion concentration reach 42%, add 8kg vinyl acetate synthetic agent, 0.55kg sodium hydroxide catalyst, 0.2kg alum, react 4.5 hours, pH value is more than 7, Then carry out solid-liquid separation, washing, drying, packaging and storage.

Embodiment 3

[0018] Example 3: Get 45kg of modified starch with a particle size of 100 mesh and 60kg of water, add 0.44kg of potassium permanganate oxidizing agent in turn, fully react at normal temperature, make the starch gelatinization, add 0.35kg of vinyl acetate emulsion after 120 minutes to terminate agent. Carry out solid-liquid separation then, after separation finishes, add water, make emulsion concentration reach 40%, add 7kg vinyl acetate synthetic agent and 0.5kg sodium hydroxide catalyst and 0.2kg alum, react 5 hours, pH value is more than 7, then Then carry out solid-liquid separation, washing, drying, packaging and storage.

Abstract

The invention discloses a quick-drying carton adhesive which is made from raw materials in parts by weight as follows: 40-55 parts of modified starch, 50-66 parts of water, 0.15-0.25 part of nano sepiolite powder, 0.4-0.45 part of potassium permanganate, 0.18-0.25 part of vinyl acetate emulsion, 6.5-8 parts of vinyl acetate, 0.4-0.55 part of sodium hydroxide and 0.05-0.20 part of alum. The quick-drying carton adhesive has the advantages of better paper property, excellent flowability and low possibility of moisture absorption and saltpetering.

Description

[0001] technical field [0002] The invention relates to a starch adhesive, in particular to a quick-drying carton adhesive for carton bonding. Background technique [0003] In the production of paper products, especially corrugated boxes, natron has been used for decades. Because it is highly alkaline and easy to absorb moisture, it often returns to alkali and whitens, causing paper products to deform, peel off, and even corrode products, resulting in huge economic losses such as deterioration and scrapping. Therefore, starch adhesives have been used to replace natron in foreign countries since the 1950s, and starch adhesives have been studied in China since the end of the 1970s, and gradually popularized in the production of paper products in the 1980s. [0004] There are many disclosures about the formulation and production process of starch adhesives in the prior art, among which there are hundreds of patent technical documents found on the website of the State Intellec...
