Embodiment Construction

[0007] Take 40 kg of corn starch with a particle size of 100 mesh and mix with 50 kg of water, add 0.4 kg of potassium permanganate oxidizer and 0.2 kg of ammonia stabilizer in sequence, fully react at room temperature to gelatinize the starch, and add 0.2 kg of oxalic acid terminator 100 minutes later. Then carry out solid-liquid separation. After separation, add water to make the emulsion concentration reach 40%, add 6.5kg vinyl acetate synthesizer and 0.4kg sodium hydroxide catalyst, react for 4 hours, the pH value is above 7, and then proceed to solid-liquid Separation, washing, drying, packaging and storage.

Abstract

The starch adhesive SSS-85 has corn starch and water as main components and contains also stabilizer, oxidant, terminating agent, catalyst, etc. The adhesive is chemically modified neutral grafted starch and is specially for coating pigment. Compared with conventional starch, the present invention has less retrogradation and high compatibility, and is suitable for compounding pigment paint with high solid content and low viscosity. The present invention is suitable for painting various paper products.

Description

Technical field [0001] The invention relates to a starch adhesive, in particular to a component of a starch adhesive used in the paper mounting industry. Background technique [0002] In the paper mounting industry, adhesives are used in the sizing, coating, glazing, and primer of all types of paper and cardboard. Compared with polyvinyl alcohol adhesive, starch adhesive has lower raw material price and simple production process, so the cost is lower and the quality is also improved. However, the existing starch adhesives, due to their insufficient composition and content, cannot meet the requirements of high-grade coated paper and cardboard, light-weight coated paper and cast coated paper due to their paper-forming properties and coating fluidity. Claim. Summary of the invention [0003] The technical problem to be solved by the present invention is to overcome the shortcomings of the existing starch adhesives and provide a starch adhesive (SSS-85) with good paper-forming prope...
