However, the coating formed by the fireproof coating has larger pores and lower bonding strength, and heat is conducted through the pores of the coating, so that the fireproof time of the coating is shortened, and the fireproof performance of the coating is reduced.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a fireproof coating structure to solve the technical problems of short fireproof time and poor fireproof performance of the conventional fireproof coating.
In order to achieve the purpose, the specific technical scheme of the fireproof coating structure is as follows:
the utility model provides a fire protection coating structure, includes a plurality of interval distribution and the flame retardant coating and the filling layer that connect gradually, the quantity of flame retardant coating is 2-4 layers, the quantity of flame retardant coating is less than or equal to the quantity of filling layer.
Preferably, the fire-proof layer is formed by spraying non-expansive fire-proof paint.
Preferably, the filling layer is a nano inorganic high-temperature resistant coating.
Preferably, the thickness of the fire-proof layer is 8-10 mm.
Preferably, the thickness of the filling layer is 20 microns.
The fireproof coating structure of the utility model has the following advantages: the laminated composite fireproof structure is formed by the fireproof layer formed by the non-intumescent fireproof coating and the filling layer formed by the nano inorganic high-temperature-resistant coating, the filling layer in the structure permeates into the hole of the fireproof layer, the effect of heat transfer convection effect in the hole is achieved, the fireproof time of the fireproof coating is prolonged, meanwhile, the nano inorganic high-temperature-resistant coating also achieves the bonding effect, the overall strength of the fireproof coating is improved, and the risk that the fireproof coating falls off and cracks is reduced.
Drawings
FIG. 1 is a schematic structural view of embodiment 1 of the present invention;
FIG. 2 is a schematic structural diagram of embodiment 2 of the present invention;
the notation in the figure is: 1. a fire barrier layer; 2. and (5) filling the layer.
Detailed Description
For better understanding of the objects, structure and function of the present invention, a fireproof coating structure of the present invention will be described in further detail with reference to the accompanying drawings.
Example 1:
as shown in figure 1, a fire protection coating structure, including the flame retardant coating 1 that is formed by the spraying of non-inflation fire retardant coating, spraying thickness is 8 millimeters, non-inflation fire retardant coating includes high temperature resistant cement, expanded perlite, expanded vermiculite and calcium carbonate mix the preparation and form, filling layer 2 is formed by the spraying of inorganic high temperature resistant coating of nanometer, spraying thickness is 20 microns, inorganic high temperature resistant coating of nanometer includes the inorganic emulsion of nanometer, the organosilicon emulsion, talcum powder and glass powder mix the preparation and form, the quantity of flame retardant coating 1 is 2 layers, the quantity of filling layer 2 is 1 layer, flame retardant coating 1 and 2 interval distribution of filling layer and connect gradually. This fire protection coating is when the construction, spraying flame retardant coating 1 in proper order on the base member that needs the fire prevention, filling layer 2 and flame retardant coating 1, in filling layer 2 can permeate the hole that gets into flame retardant coating 1, heat transfer convection effect in the separation hole, improve fire protection coating's fire prevention time, in order to improve fire behavior, filling layer 2 has still played the effect of bonding between two flame retardant coatings 1 simultaneously, fire protection coating bulk strength has been increased, the risk that fire protection coating drops the fracture has been reduced.
Example 2:
as shown in fig. 2, the fire protection coating of example 2 is based on example 1, with the main difference that the thickness of the fire protection layer 1 is 10 mm, the number of fire protection layers 1 is 4, and the number of filling layers 2 is 4. When the fireproof coating is constructed, the fireproof layer 1, the filling layer 2, the fireproof layer 1 and the filling layer 2 are sequentially sprayed on a base body needing to be fireproof, the whole fireproof time and the fireproof performance of the fireproof coating can be effectively improved by increasing the number of the fireproof layers 2 and the thickness of the single-layer fireproof layer 2, when the number of the filling layers 2 is one layer less than that of the fireproof layers 1, the filling layer 2 is positioned between the two fireproof layers 2, when the outermost fireproof layer 1 is sprayed, the filling layer 2 sprayed before the outermost fireproof layer 1 is dried, the permeation effect of the outermost fireproof layer 1 is poor, the fireproof time of the outermost fireproof layer 1 is reduced, and therefore, the pores of the outermost fireproof layer 1 can be effectively filled by the filling layer 2 by spraying the filling layer 2 on the outermost fireproof layer 1, the whole fireproof time and fireproof performance of the fireproof coating are improved.
It is to be understood that the present invention has been described with reference to certain embodiments, and that various changes in the features and embodiments, or equivalent substitutions may be made therein by those skilled in the art without departing from the spirit and scope of the utility model. In addition, many modifications may be made to adapt a particular situation or material to the teachings of the utility model without departing from the essential scope thereof.
