Abstract

The invention discloses a preparation method of a flame-retardant coating for fireproof wooden doors. The flame-retardant coating is prepared from water-based resin, two types of flame retardants, melamine, modified ammonium polyphosphate, nanoscale silicon dioxide, organosilicone-modified styrene-acrylic emulsion, dispersant, defoaming agent, stabilizer, filler and water. The VOC (volatile organic compound) content of the coating is low, halogen flame retardant is not contained, the fireproof property is excellent, the physicochemical properties are excellent, and the flame-retardant coating does not produce highly carcinogenic and poisonous gas and smoke when encountering fire; the thickness of the coating layer is small, the materials for preparation are environment-friendly and safe, the preparation method is simple and efficient, and the degree of industrialization is high; furthermore, when the flame-retardant coating is applied to the finishing of a wooden door, under the premise of environment protection and safety, the flame-retardant, heat-insulating and fireproof properties of the wooden door are effectively increased, and thereby the application of the wooden door in certain places with high fireproof requirement is greatly broadened.

Description

technical field [0001] The invention relates to the field of preparation of wooden doors, in particular to a preparation method of a flame-retardant coating for fire-resistant wooden doors. Background technique [0002] With the continuous improvement of people's living standards, wooden doors have gradually developed from basic decoration and safety requirements to multi-functional requirements. Ordinary wooden doors should also have some specific functions for specific places of use. Since the essential materials of wooden doors are wood, Its fire-proof and flame-retardant properties are generally poor, which will increase the danger in the event of a fire, and its heat insulation performance is poor. [0003] At present, wood with better fire resistance performance is used to make fire doors, but its flame retardant and heat insulation performance is still not good, and the cost of the material itself is also high. Water-based paint with flame retardant and heat insulatio...
