Description
Technical Field
The invention belongs to the technical field of flame retardant coatings, and relates to a water-based ultrathin steel structure fireproof coating and a preparation method thereof.
Background
The steel structure has light dead weight, high strength, large span, large space, good shock resistance, convenient hoisting and short construction time, and is widely applied to the modern building industry. As a non-combustible building material, under the action of fire and high temperature, the mechanical properties (such as yield strength, tensile strength, elastic modulus and the like) of steel are reduced along with the rise of temperature, and are rapidly reduced at 450-650 ℃, so that the bearing capacity is lost, the deformation is huge, steel columns and steel beams are bent, the building collapses, and the fire resistance limit of a steel structure which is not protected generally is about 15 min.
The fireproof paint is a functional building paint, which is applied to the surface of building materials to decorate and protect the building materials. The flame retardant property of the coating can inhibit the spread of flame within a certain period of time, and plays a role in fire protection for related components so as to prevent the components from being damaged in fire. The steel structure fireproof coating can prolong the fire resistance limit of a structure to 3h or even higher on the premise of not changing the properties of steel, and can save time for rescuing people and effectively reduce the loss of lives and properties caused by fire for evacuating people under the condition of fire.
The steel structure fire-retardant coating can be divided into an organic solvent type and a water solvent type according to the type of the solvent. A large amount of organic solvent is released in the production, transportation and coating brushing process of the traditional organic solvent, and the volatilization of the organic solvent easily causes fire, damages the health of human bodies, causes serious environmental pollution and problems, and does not meet the requirements of safety, environmental protection and green development.
The main solvent of the water-based steel structure coating is water, part of organic auxiliary agents exist, the pollution is small, and the water-based steel structure coating meets the requirements of environmental protection and gradually replaces the solvent-based steel structure fireproof coating by virtue of the advantage of low pollution. However, the existing water-based ultrathin steel structure fireproof coating has poor fireproof performance (the fire resistance limit of a 2mm coating of part of the fireproof coating is only 30 mim), and the requirement of the existing large-scale steel structure on the fireproof coating performance can not be met.
Disclosure of Invention
The invention aims to solve the problem that the fire-resistant time is short (less than 60 min) at high temperature (450-650 ℃) of the existing water-based ultrathin steel structure fireproof coating, and provides the ultrathin steel structure fireproof coating and the preparation method thereof.
In order to achieve the purpose, the technical scheme adopted by the invention is as follows:
the water-based ultrathin steel structure fireproof coating is characterized by being prepared from the following raw materials in percentage by mass:
film-forming material: 20% -30% of silicone-acrylic emulsion;
dehydration catalyst: 20% -30% of ammonium polyphosphate;
a char-forming agent: 10% -15% of pentaerythritol and dipentaerythritol;
