Problems solved by technology

[0003] Among them, although flame-retardant coatings have excellent flame-retardant properties, their adhesion and integrity are poor, and they are prone to peeling and peeling. For places with high frequency of use, such as the ground and desktop workbenches, their lifespan is short and their durability is poor. , and the flame retardant coatings constructed on site have environmental pollution problems such as solvent volatilization and strong odor
[0004] Although the overall performance of thermoplastic flame-retardant coil is good, it also has a certain flame-retardant function, which can prevent the flame from continuing to burn; however, because this type of coil is a thermoplastic material, its characteristics determine that it will be deformed once it is heated, so it cannot continue to be used. , poor aesthetics, such as: cigarette butts falling on thermoplastic materials will cause severe yellowing, wrinkling, deformation, and local bulges

Abstract

The invention discloses a flame-retardant coiled material and a preparation method thereof. The flame-retardant coiled material is a laminated structure which is formed by bonding a flame-retardant surface layer and a chopped fiber layer by a flame-retardant paint and carrying out curing. The flame-retardant paint is composed of a component A and a component B in a weight ratio of 10:(2-5). The component A comprises the following ingredients in percentage by mass: an epoxy resin, a flame-retardant resin, a flame-retardant diluter, a toughener, a dispersing agent, a defoaming agent, a leveling agent, a flame-retardant additive, a color paste and the balance of inorganic filler. The component B comprises a curing agent and the balance of curing accelerator. The flame-retardant additive comprises at least one of antimony trioxide, aluminum hydroxide, magnesium hydroxide, melamine cyanurate, chlorinated paraffin, tri(2-chloropropyl) phosphate and dimethyl methylphosphate. The epoxy resin, flame-retardant resin, flame-retardant diluter and flame-retardant additive are utilized to form the compound system, thereby fully displaying the synergistic effects of the components, and greatly enhancing the flame retardancy of the flame-retardant paint.

technical field [0001] The invention relates to the technical field of polymer coatings and coiled materials, in particular to a flame-retardant coiled material and a preparation method thereof. Background technique [0002] With the continuous advancement of science and technology, more and more attention has been paid to the flame retardancy of materials. The existing flame-retardant coverings for floors, walls, and desktops are mainly flame-retardant coatings and thermoplastic flame-retardant coils for on-site construction. [0003] Among them, although flame-retardant coatings have excellent flame-retardant properties, their adhesion and integrity are poor, and they are prone to peeling and peeling. For places with high frequency of use, such as the ground and desktop workbenches, their lifespan is short and their durability is poor. , and the flame-retardant coatings constructed on site have environmental pollution problems such as solvent volatilization and strong odor...
