Problems solved by technology

However, because the LOI of this type of polymer is relatively low, it is easy to be ignited by gaseous substances in the air, and a large amount of smoke is released during the combustion process, which not only causes serious property losses, but also endangers the lives of the people, making it The application in some special fields is subject to certain restrictions

Embodiment 1

[0022] The present invention provides a kind of epoxy acrylic resin flame retardant paint, by weight percentage, described paint comprises following raw material:

[0023]

[0024] The epoxy acrylate prepolymer is a polymer composed of epoxy resin and acrylate monomer, and the epoxy resin is heated to 50-70°C under the conditions of passing nitrogen into the epoxy resin for protection and stirring Slowly add the acrylate monomer dropwise, and control the dropping within 1-1.5h. After the dropwise addition, raise the temperature of the system to 80-90°C, react at a constant temperature for 2-3h, cool to room temperature and discharge to obtain The epoxy acrylate prepolymer, wherein the epoxy resin is an alicyclic epoxy resin or an aliphatic epoxidized olefin compound or glycerol ester; the acrylate monomer is methyl acrylate and / or Or ethyl acrylate and / or methyl methacrylate and / or butyl methacrylate; the weight ratio of the epoxy resin to the acrylate monomer is 1-1.5:1.5-...

Embodiment 2

[0035] On the basis of embodiment 1, present embodiment 2 is as the preferred embodiment of the present invention, and a kind of epoxy acrylic resin flame retardant coating, by weight percentage, comprises following raw material:

[0036]

[0037] Wherein, the preparation method of the flame retardant coating is the same as in Example 1.

Embodiment 3

[0039] On the basis of embodiment 1, present embodiment 3 is as the preferred embodiment of the present invention, and a kind of epoxy acrylic resin flame retardant coating, by weight percentage, comprises following raw material:

[0040]

[0041]

[0042] Wherein, the preparation method of the flame retardant coating is the same as in Example 1.

Abstract

The invention discloses an epoxy acrylic resin flame-retarding coating and a preparation method thereof, wherein the coating includes, by weight, 20-40 parts of an epoxy acrylate prepolymer, 15-40 parts of a flame retardant, 0.5-1.5 parts of an initiator, 4-10 parts of a pigment, 1.5-3.5 parts of a dispersant, 4-10 parts of inorganic filler, 2-5 parts of a defoamer, 2-6 parts of a film-forming additive, and 5-30 parts of a solvent. By adding the reactive flame retardant that can form completely compatible entirety with the epoxy acrylate prepolymer, the flame-retarding coating not only has excellent and durable flame-retarding effect, but also has excellent physical and mechanical performance, water resistance and anti-chemical corrosion effect and high adhesion strength.

Description

technical field [0001] The invention belongs to the field of coatings, and in particular relates to an epoxy acrylic resin flame-retardant coating and a preparation method thereof. Background technique [0002] Flame retardant coating is to brush the paint on the surface of flammable materials, which can usually play a certain decorative role. Once a fire occurs, it can slow down the speed of flame spread and prevent burning within a certain period of time, so as to protect the substrate and make people Also enough time to leave the fire and organize rescue purposes. The fire prevention principle of flame retardant coatings can be roughly summarized into the following five points: (1) The fire retardant coating itself is flame retardant or non-combustible, so that the protected substrate is not directly in contact with the air, delaying the ignition of objects and reducing the burning speed; (2) ) In addition to being flame retardant or non-combustible, the fire retardant c...
