Embodiment 1

[0041] The purpose of the present invention is achieved through the following technical solutions.

[0042] The preparation method is as follows, and the components are as follows in parts by mass:

[0043]

[0044] The neoprene is neoprene CR322, using the CR322 model produced by Chongqing Changshou Chemical Co., Ltd. The oxygen index of neoprene is 50%. Generally, the oxygen index is more than 27%, which is a self-extinguishing material, which can improve the flame retardancy. The oxygen index of this type of neoprene CR322 is higher than that of general materials, and it has strong self-extinguishing performance.

[0045] Carbon black is made of N220, N330, N550, N774, and N990, and the mass parts are 1:2:2:1:4. Among them, carbon black N220 and carbon black N330 can greatly improve the rubber strength, but a large amount of use will cause Reduce tensile elongation, carbon black N550, carbon black N774, carbon black N990 have slightly poorer reinforcement performance, b...

Embodiment 2

[0063] The purpose of the present invention is achieved through the following technical solutions.

[0064] The preparation method of the present embodiment is the same as that of Example 1, and its difference is that the quality of each material, the components are as follows in parts by mass:

[0065]

[0066]

[0067] The oxygen index of neoprene is 40%. Generally speaking, the oxygen index of more than 27% is a self-extinguishing material, which can improve the flame retardant performance. The oxygen index of neoprene is higher than that of general materials, and it has strong self-extinguishing performance.

[0068] Carbon black is compounded from N220, N330, N550, N774, and N990, and the mass parts are 1:2:2:1:4.

[0069] Choose stearic acid 1803 for stearic acid. The stearic acid 1803 uses animal fat as the main raw material, which greatly improves the degree of activation, greatly improves the vulcanization speed and degree of rubber preparation, and reacts faste...

Embodiment 3

[0073] The purpose of the present invention is achieved through the following technical solutions.

[0074] The preparation method of the present embodiment is the same as that of Example 1, and its difference is that the quality of each material, the components are as follows in parts by mass:

[0075]

[0076]

[0077] The oxygen index of neoprene is 30%, and generally the oxygen index exceeds 27%, which is a self-extinguishing material, which can improve the flame retardant performance. The oxygen index of neoprene is higher than that of general materials, and it has strong self-extinguishing performance.

[0078] Carbon black is compounded from N220, N330, N550, N774, and N990, and the mass parts are 1:2:2:1:4.

[0079] Stearic acid selects stearic acid 1842, and its stearic acid 1842 takes animal fat as the main raw material.

[0080] The mass fraction of aluminum hydroxide is 20 parts, and the synergistic effect is obvious when superfine aluminum hydroxide and hal...

Abstract

The invention discloses an aluminium hydroxide flame retardant adhesive and a preparation method thereof, and belongs to the field of flame retardant materials. The aluminium hydroxide flame retardant adhesive comprises the following components in parts by mass: 40 parts of a chloroprene rubber adhesive, 60 parts of natural rubber, 2 to 5 parts of an anti-aging agent RD, 7 to 15 parts of phenolic resin 12687, 1 to 6 parts of stearic acid, 4 to 10 parts of magnesium oxide, 10 to 30 parts of argil, 10 to 30 parts of carbon black, 20 to 25 parts of aluminium hydroxide, 8 to 14 parts of paraffin oil, 1 to 3 parts of an accelerant M, 1 to 3 parts of an accelerant DM, and 2 to 4 parts of sulphur. Aluminium hydroxide is processed in a plastication starting stage by using a two-stage plastication way. The aluminium hydroxide flame retardant adhesive provided by the invention has a good flame retardant efficiency, the escape of combustible gases can be prevented by using aluminium hydroxide, the formation of soot is avoided, a better flame retardant and smoke suppression effect is played, the tensile strength is high, the stretch rate is good, the production process is simple, and the manufacturing cost and the manufacturing difficulty are lowered.

Description

technical field [0001] The invention relates to the field of flame retardant materials, and more specifically relates to an aluminum hydroxide flame retardant glue and a preparation method thereof. Background technique [0002] Flame-retardant rubber refers to the rubber that can delay ignition, reduce the speed of flame propagation, and its own burning flame can quickly extinguish itself after leaving the flame. Flame retardant rubber can be decomposed into non-toxic gas when burning, so as to shield the heat source and oxygen, so as to play a flame retardant effect. All additives that can reduce the ease of ignition of plastics and the speed of flame propagation are called flame retardants. Most flame retardants are compounds of Group V, VII and III elements in the periodic table. Such as the compounds of nitrogen, phosphorus and antimony of Group V, the compounds of chlorine and bromine of Group VII and the compounds of boron and aluminum of Group III. In addition, com...
