Problems solved by technology

It is mainly coated with a layer of flame retardant glue or flame retardant on the surface of the cloth. However, the fire retardant glue or flame retardant in the prior art has poor flame retardancy. The smoke makes people suffocate after inhalation; moreover, the fire-resistant glue on the fabric in summer is prone to anti-alkali, damp, sour, oil stains, etc., and the flame-retardant glue on the fabric will gradually volatilize over time and fall off easily, 1-2 years After losing the flame retardant performance

Embodiment 1

[0046] (a), based on the total weight of activated carbon flame retardant glue 100%, weigh 10% of expanded graphite and add 50% of the water with a temperature above 85°C, mix and stir evenly to prepare A solution, and continue to heat A solution to make it The temperature is maintained above 85°C;

[0047] (b), by weighing 100% of the weight of the binder, take by weighing 5% of acrylic acid, 95% of methyl methacrylate, and mix and stir evenly to prepare the binder; The binding agent is added in the A solution and stirred and mixed evenly to obtain the B solution;

[0048] (c), when the temperature of solution B drops to room temperature, add ammonia water to adjust the pH value of solution B to 6-7.

Embodiment 2

[0050] (a), according to the total weight of activated carbon flame-retardant glue 100%, weigh 20% of expanded graphite and add 45% of water with a temperature above 85°C, mix and stir evenly to prepare A solution, and continue to heat A solution to make it The temperature is maintained above 85°C;

[0051] (b), according to 100% of binder weight, take by weighing 15% of acrylic acid, 40% of methyl methacrylate, 45% of ethyl methacrylate, mix and stir evenly to prepare binder; In terms of 100% by weight, add 35% of the binder into the A solution and stir and mix evenly to prepare the B solution;

[0052] (c), when the temperature of solution B drops to room temperature, add ammonia water to adjust the pH value of solution B to 6-7.

Embodiment 3

[0054] (a), based on the total weight of activated carbon flame retardant glue 100%, weigh 50% of expanded graphite and add 20% of water with a temperature above 85°C, mix and stir evenly to prepare A solution, and continue to heat A solution to make it The temperature is maintained above 85°C;

[0055] (b), based on 100% of the weight of the binder, weigh 35% of acrylic acid, 48% of methyl methacrylate, 12% of ethyl methacrylate, and 5% of butyl methacrylate, and mix and stir evenly to obtain a bond agent; according to 100% of the total weight of the activated carbon flame-retardant adhesive, 30% of the binder is added to the A solution and stirred and mixed evenly to obtain the B solution;

[0056] (c), when the temperature of solution B drops to room temperature, add ammonia water to adjust the pH value of solution B to 6-7.

Abstract

The invention provides an activated carbon flame-retardant adhesive, which is prepared from the following raw materials: 10-50% of expanded graphite, 10-40% of binder, and the balance of water on the basis of 100% of weight. The invention also provides a method for preparing the activated carbon flame-retardant adhesive. The method comprises the following steps: (a) weighing 10-50% of expanded graphite according to the weight percent, and adding to water of which the temperature is more than 85 DEG C to evenly mix and stir, so as to prepare a solution A, lastingly heating the solution A, so that the temperature of the solution A is maintained over 85 DEG C; (b) weighing 10-40% of binder according to the weight percent, and adding to the solution A to evenly stir and mix, so as to prepare a solution B; (c) adding ammonia water to adjust the PH value of the solution B to 6-7 when the temperature of the solution B is reduced to room temperature. The activated carbon flame-retardant adhesive provided by the invention not only is good in flame retardant property, but also is not affected with dampness due to environmental influence, and is free of pollution.

Description

technical field [0001] The invention relates to a fireproof material, in particular to an activated carbon fireproof glue. Background technique [0002] As a kind of fireproof material, fireproof fabric has been widely used in large hotels, conference rooms, cinemas, multi-functional halls, stadiums and other occasions. It is mainly coated with a layer of flame retardant glue or flame retardant on the surface of the cloth. However, the fire retardant glue or flame retardant in the prior art has poor flame retardancy. The smoke makes people suffocate after inhalation; moreover, the fire-resistant glue on the fabric in summer is prone to anti-alkali, damp, sour, oil stains, etc., and the flame-retardant glue on the fabric will gradually volatilize over time and fall off easily, 1-2 years After that, it loses its flame retardant performance. Contents of the invention [0003] The purpose of the present invention is to solve the above-mentioned defects in the prior art, and ...
