Abstract

The invention discloses a polyurethane waterproof flame-retardant paint and a preparation method thereof. The paint comprises polyurethane prepolymers, diacetone acryloamide, buty stearate, titanate coupling agent TMC-311 and titanium pigment. The paint further comprises polydimethyl siloxane, white carbon black, mixed solvent and flame-retardant materials. The preparation method comprises the following steps: dissolving the diacetone acrylamide by ethanol of which the volume concentration is 65-80%, wherein the adding amount of the ethanol is 1.5 kilograms in per kilogram of diacetone acrylamide on the basis of weight; mixing the dissolved diacetone acrylamide with the polyurethane prepolymers in a reaction kettle, wherein the reaction temperature is 75-119 DEG C and the reaction time is 1.2-1.5 hours; adding the titanate coupling agent TMC-311 into the mixture and further reacting for 3-6 hours; then adding buty stearate, the rutile-type titanium pigment, polydimethyl siloxane, the flame-retardant materials, the white carbon black and the mixed solvent into the mixture and uniformly mixing, so that the polyurethane waterproof flame-retardant paint product is obtained. The paint prepared by the preparation method is good in waterproof and flame-retardant effects, friendly to the environment and not easy to age.

Description

technical field [0001] The invention relates to a flame-retardant coating, in particular to a polyurethane waterproof flame-retardant coating and a preparation method thereof. Background technique [0002] With the development of the construction industry, the demand for coatings is increasing day by day. Paint is a material that can be coated on the surface of an object by different construction techniques to form a solid film with firm adhesion, certain strength, and continuity. . Objects are exposed to the atmosphere and are corroded by oxygen, moisture, etc., which are likely to cause damage such as metal corrosion, wood decay, and cement weathering. Applying paint to the surface of the object forms a protective film, which can prevent or delay these damages. Occurrence and development can extend the service life of various materials. [0003] Polyurethane coating is an important architectural coating and can also be used as industrial coating. It is a new type of mat...
