Problems solved by technology

[0002] In recent years, there have been frequent occurrences of fires in absorption towers of power plants under construction or already under construction, causing huge economic losses and potential safety hazards
In essence, it is because the materials used on site have no flame retardancy. Once the fire is not self-extinguishing, the material will quickly catch fire and cause huge economic losses to the owner.

preparation example Construction

[0044] The preparation method of the above-mentioned flame-retardant hybrid polymer coating, which includes:

[0045] S1. Coating the surface of the base material to form a primer layer.

[0046] For example, the curing agent and the organic-inorganic hybrid silicate nano-composite material are mixed in proportion, coated on the surface of the substrate, and dried to form the primer layer. Wherein, the coating process can be controlled by a microcomputer to make it produce accurately, or it can be done manually, which is not limited here.

[0047] Wherein, in a preferred embodiment of the present invention, drying is performed at 40-50° C. for 2-5 minutes, and then dried naturally at 10-30° C. Effectively promote the hardening of the undercoat, and at the same time bake at 40-50°C for 2-10min, effectively improve the bonding firmness between the undercoat and the substrate.

[0048] S2. Spray coating on the side of the primer layer away from the surface of the substrate to f...

Abstract

The invention provides a flame-retardant hybrid polymer coating and a preparation method thereof, and relates to the field of materials. The flame-retardant hybrid polymer coating comprises an undercoat layer, a structural layer and a surface coating which are sequentially laid on the surface of a substrate. The raw materials of the undercoat layer comprise a curing agent, and organic and inorganic hybrid silicate nano composite materials. The raw materials of the structural layer comprise a curing agent, a flame retardant, organic and inorganic hybrid silicate nano composite materials, and afiller. The raw materials of the surface coating comprise a curing agent, and organic and inorganic hybrid silicate nano composite materials, so that the surface coating has good corrosion resistanceand flame retardance, and the occurrence of a fire disaster is effectively reduced. The preparation method of the flame-retardant hybrid polymer coating is simple to operate and can effectively improve the performance of the coating coated with a flame-retardant hybrid polymer.

Description

technical field [0001] The invention relates to the field of materials, and in particular to a flame-retardant hybrid polymer coating and a preparation method thereof. Background technique [0002] In recent years, there have been frequent occurrences of fires in absorption towers of power plants under construction or already under construction, causing huge economic losses and potential safety hazards. In essence, it is because the materials used on site have no flame retardancy. Once the fire is over, there is no self-extinguishing property, resulting in rapid ignition and combustion of the materials, which brings huge economic losses to the owner. Contents of the invention [0003] The purpose of the present invention is to provide a flame-retardant hybrid polymer coating, which has better anti-corrosion performance and flame retardancy, and can effectively reduce the occurrence of fire. [0004] Another object of the present invention is to provide a method for prepar...
