Abstract
The invention discloses a polyamide wax composition, a preparation method and application thereof, wherein the composition comprises polyamide wax and a mixed solvent for dispersing the polyamide wax, wherein the mixed solvent is composed of isopropanol and N-methyl pyrrolidone; the composition can be mixed at a mixing temperature of below 60 ℃ and/or a stirring speed of below 200rpm to obtain the polyamide wax composition containing the activated polyamide wax, so that the construction difficulty and the construction cost can be greatly reduced in the preparation process of the polyurethane waterproof coating, the polyurethane waterproof coating is endowed with excellent anti-sagging performance, and the excellent anti-sagging effect can be obtained on a base surface at a higher temperature in time.
Description
Technical Field
The invention belongs to the field of building waterproofing, and particularly relates to a polyamide wax composition, and a preparation method and application thereof.
Background
Currently, the polyurethane on the market has anti-sagging performance, and a thixotropic agent is usually added, wherein polyamide wax is a more common thixotropic agent. Polyamide waxes are mainly composed of two parts, a non-polar aliphatic hydrocarbon part and a polar amide functional group. The oxygen atom in the amide group has large electronegativity and is easy to form a hydrogen bond with the hydrogen atom of the alkyl part, the hydrogen bond can be formed between molecules or in molecules, the intra-molecular hydrogen bond enables the molecules to be in a curled shape, the whole molecule basically shows a nonpolar state to the outside, a three-dimensional network structure is difficult to establish, and then the thixotropic effect cannot be realized; the intermolecular hydrogen bond can form a three-dimensional network structure in the coating system, and the establishment of the structure enables the coating to have the anti-sagging performance. The polyamide wax is easy to form intramolecular hydrogen bonds under the conventional storage condition, so that the polyamide wax is fully dispersed into uniformly dispersed molecular individuals in a straightened state by high-speed shearing and high-temperature activation treatment at about 120 ℃ in a solvent before use, is more compatible with a polyurethane system, can effectively disperse most colloids and generate a rheological activated network structure, provides excellent thixotropic property, and realizes viscosity establishment, sagging control and pigment and filler suspension control. However, the high-speed shearing and higher-temperature activation treatment mode has high requirements on production equipment, and meanwhile, the treatment needs to be carried out on site, so that the construction difficulty and the construction cost are greatly increased.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provide a novel polyamide wax composition, which can realize the activation treatment of polyamide wax by simply stirring at a low speed and/or at a lower activation temperature, greatly improves the construction convenience and saves the construction cost.
The invention also provides a preparation method of the polyamide wax composition.
The invention also provides a method for activating the polyamide wax by the polyamide wax composition.
The invention also provides an application of the polyamide wax composition in polyurethane waterproof paint.
In order to achieve the purpose, the invention adopts a technical scheme that:
a polyamide wax composition comprising a polyamide wax and a mixed solvent for dispersing the polyamide wax, the mixed solvent being composed of isopropyl alcohol and N-methylpyrrolidone.
According to some preferred aspects of the present invention, the feed mass ratio of the isopropanol to the N-methylpyrrolidone is 1: 0.5-2.5.
Further, the feeding mass ratio of the isopropanol to the N-methyl pyrrolidone is 1: 1.1-2.3.
