Abstract

The invention provides a normal-temperature and quick-bonding waterproof adhesive for a paper product and a preparation method of the normal-temperature and quick-bonding waterproof adhesive. The normal-temperature and quick-bonding waterproof adhesive is characterized by being prepared by reacting water, alkali-soluble acrylate emulsion, filler, a cross-linking agent, a TL water-proofing agent, emulsified silicone oil, Kathon, sodium hexametaphosphate and ammonium hydroxide according to certain proportions, a certain process and requirements. The adhesive provided by the invention has the advantages of wide applicability, high initial adhesiveness, low cost, good water resistance and the like; the requirements of low-temperature production of paper products such as corrugated paper board and honeycomb paperboard production lines are met.

Description

technical field [0001] The invention relates to the field of polymer material adhesives, in particular to an adhesive for fast-bonding water-resistant paper products at room temperature and a preparation method thereof. Background technique [0002] At present, most of the adhesives used in the production of paper products such as corrugated cardboard, honeycomb cardboard, and cartons are starch adhesives, polyvinyl alcohol modified adhesives, white latex, etc. Starch adhesives have a wide range of raw materials and a simple glue-making process. , starch, alkali, borax, oxidizing agent, stabilizer, etc., according to a certain proportion and a certain order of stirring reaction, but in the actual use process, there are slow drying speed, slow speed, poor water resistance, and the corrugated cardboard produced is easy to get damp Softening, resulting in a decrease in bond strength and a decrease in edge pressure strength. Another prominent disadvantage of using ordinary star...
