Problems solved by technology

[0006] The above-mentioned patents all have the effect of fire prevention and flame retardancy. However, the flame-retardant principle of the above-mentioned patents is to delay or inhibit the combustion of polymers by relying on the expansion and heat insulation layer formed by the flame-retardant coating itself which is difficult to burn or volume expansion. There is no or little chemical action between them, but the flame retardancy produced by this action is not high, and a little harmful gas will also be produced

Abstract

The invention relates to the technical field of flame-retardant coatings, in particular to smokeless toxic flame-retardant back glue and a production process thereof. The smokeless toxic flame-retardant back glue is prepared from the following components in percentages by weight: 3-5% of a foaming agent, 15-22% of a crosslinking agent, 15-20% of expandable graphite, 5-8% of a flame retardant, 2-3%of a leveling agent, 1-2% of a thickener and the balance of water. The invention also relates to a process for preparing the smokeless toxic flame-retardant back glue. The process comprises the following steps: (1) weighing: inspecting various raw materials according to requirements, and weighing the various raw materials according to a formula proportion for later use; (2) sequentially adding the foaming agent, the crosslinking agent and the expandable graphite into a stirring tank, and uniformly stirring; (3) adding the flame retardant and the leveling agent while stirring, and uniformly stirring; and (4) sequentially adding the thickener and the water, and stirring to obtain the uniform flame-retardant back glue. The flame-retardant back glue disclosed by the invention has the advantages of good flame-retardant effect, high safety performance, simple preparation process, economy, environmental friendliness and no generation of flue gas and poison gas.

Description

technical field [0001] The invention relates to the technical field of flame-retardant coatings, in particular to a smoke-free and toxic flame-retardant back coating and a production process thereof. Background technique [0002] Flame retardant back coating is to brush the paint on the surface of flammable materials, which can improve the fire resistance of the material, slow down the speed of flame spread, or prevent burning within a certain period of time, also known as fire retardant paint. Fireproof coating is a special coating used on the surface of flammable substrates, which can reduce the flammability of the surface of the coated material, retard the rapid spread of fire, and improve the fire resistance limit of the coated material. [0003] With the development of my country's synthetic material industry and the continuous expansion of application fields, fire-resistant coatings have broad market prospects in various fields such as chemical building materials, elec...
