Embodiment Construction

[0007] Take 40kg of cornstarch with a particle size of 100 mesh and 50kg of water, add 0.4kg of potassium permanganate oxidant and 0.2kg of ammonia water stabilizer in turn, react fully at room temperature to gelatinize the starch, and add 0.2kg of oxalic acid terminator after 100 minutes. Then carry out solid-liquid separation, after the separation, add water to make the emulsion concentration reach 40%, add 3.5kg vinyl acetate synthesis agent and 0.35kg sodium hydroxide catalyst, react for 4 hours, the pH value is more than 7, and then carry out solid-liquid Separation, washing, drying, packaging and storage.

Abstract

The starch adhesive TSS-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 the composition of the starch adhesive used in the paper laminating industry. Background technique [0002] In the laminating industry, adhesives are used for sizing, coating, glazing, and priming of various paper and cardboard. Compared with polyvinyl alcohol adhesives, starch adhesives have lower cost and better quality due to the lower price of raw materials and simpler manufacturing process. But existing starch binder, because its composition and content are unreasonable, not perfect enough, its comprehensive properties such as economy and coating fluidity, paper surface strength can't satisfy some specific needs of laminating industry at the same time. Contents 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 (TSS-85) with good economy, high coating fluid...
