Abstract

The invention discloses an organic-inorganic composite nanometer heat-insulating fire-retardant coating and a preparation method thereof. The organic-inorganic composite nanometer heat-insulating fire-retardant coating is prepared by mixing organic film-forming substance acrylic ester emulsions or styrene-acrylate emulsions, epoxide resin, organic intumescent fire-retardant system pentaerythritol, melamine and ammonium polyphosphate with inorganic fire retardant nanometer aluminum hydroxide, nanometer magnesium hydroxide, filler nanometer titanium dioxide, ceramic hollow microspheres, glass hollow microspheres and a part of auxiliary agents. The organic-inorganic composite nanometer heat-insulating fire-retardant coating disclosed by the invention not only has excellent facing property and fire-retardant property, but also achieves reflection effect on solar radiation and certain heat-insulating and heat-preserving property on a substrate, also has good adhesivity, mechanical property and hydrophobic effect, can be formed through spray coating or brush coating before being solidified, and is a novel water-based multifunctional fire-retardant material. The organic-inorganic composite nanometer heat-insulating fire-retardant coating disclosed by the invention can not only be used as a general building wall body fire-retardant coating, but also be suitable for the fire prevention of building and ornament materials, heat-insulating materials, steel structure supports, beam columns, metal roofs and the like.

Description

technical field [0001] The invention belongs to the field of chemical building materials, and in particular relates to a composite nano heat-insulating fireproof coating and a preparation method thereof. technical background [0002] Building fire prevention is an important field of fire science and technology. Our country attaches great importance to fire prevention. Many buildings require the use of fireproof coatings during construction design. Fire retardant coatings are applied on the surface of combustible substrates to decorate and protect the substrates. They can prevent the spread and spread of fire, prolong the ignition time of the substrates or the thermal insulation performance to delay the destruction time of the substrates, and provide protection for life and property safety. Favorable protection. At present, there are many kinds of fire retardant coatings, which are widely used in many fields. Fire retardant coatings have different classification methods acc...
