Abstract

The invention discloses a preparation method of a waterborne epoxy polyamine resin for a non-slip pressure-sensitive foaming coating. The preparation method comprises the following steps of S1, dissolving 500 to 580 parts by weight of epoxy resin into 500 to 580 parts by weight of a mixed organic solvent, and remarking as a solution A; S2, dissolving 200 to 230 parts by weight of diethylenetriamine into 500 to 580 parts by weight of an organic solvent, and remarking as a solution B; S3, dropwise adding the solution A into the solution B, wherein the time from starting dropwise adding to finishing dropwise adding is 1.5 to 2 hours, and the temperature of the solution A and the solution B when dropwise adding is started is 40 DEG C; controlling the reaction temperature during a dropwise adding process to be 40 to 50 DEG C, and obtaining a solution C after finishing dropwise adding; S4, cooling the solution C to 20 DEG C, dropwise adding 470 to 575 parts by weight of an organic acid, stirring for 0.5 hour, and obtaining the transparent orange waterborne epoxy polyamine resin for the non-slip pressure-sensitive foaming coating. According to the waterborne epoxy polyamine resin prepared through the method provided by the invention, the washing resistance of the foaming coating, the cohesiveness of the foaming coating and a gray fabric and the storage stability of foaming coating slurry can be improved.

Description

technical field [0001] The invention relates to the technical field of foam coating processing, in particular to a preparation method and application of a water-based epoxy polyamine resin used for anti-slip pressure-sensitive foam coatings. Background technique [0002] Foam coating is one of many advanced coating processes. After being foamed by a foaming machine, the foam coating covers a very thin film on the surface of the fabric very uniformly. The foam coating itself contains very little water, so it dries very quickly. Fast, forming a foam coating, which can save a lot of energy, is beneficial to industrial hygiene, and avoids air pollution. It is suitable for both compact fabrics and loose fabrics. It can process various fiber blended fabrics, including non-woven fabrics, and the quality index is good, which can meet product requirements, showing the vitality of foam coating processing technology. However, the foam coating foam slurry in the prior art has low cohes...
