Problems solved by technology

At present, the existing flame retardants on the market are mainly divided into two types: inorganic and organic. Among them, although the price of inorganic flame retardants is low, it affects the processing performance and physical and mechanical properties of products; although organic flame retardants affect the processing performance of products It has little effect on physical properties, but its cost is high, and it generally contains toxic substances (such as halogens) that are harmful to the human body.

Embodiment 1

[0012] Put 45 kg of white carbon black into the reaction kettle and heat up to 120°C; then add 15 kg of antimony trioxide and 40 kg of aluminum hydroxide and continue to heat up to 150°C; then add 5 kg of 120# gasoline within 3 minutes , 10 kilograms of dodecylbenzene, 1 kilogram of silane coupling agent (KH-550), 1 kilogram of dioctyl ester plasticizer and 3 kilograms of trisalt stabilizer (lead sulfate tribasic); After cooling, go out of the kettle and make Obtain the flame retardant of the present invention.

Embodiment 2

[0014] Put 70 kg of white carbon black into the reaction kettle and raise the temperature to 150°C; then add 15 kg of antimony trioxide and 15 kg of aluminum hydroxide and continue to heat up to 190°C; then add 6 kg of 200# gasoline within 4 minutes , 11 kilograms of dodecylbenzene, 1.5 kilograms of titanate coupling agent (CS-101), 2 kilograms of dibutyl ester plasticizer and 4 kilograms of di-salt stabilizer (dibasic lead phosphite); after cooling Out of the still, the flame retardant of the present invention is obtained.

Embodiment 3

[0016] Put 45 kg of white carbon black into the reaction kettle and raise the temperature to 190°C; then add 40 kg of antimony trioxide and 15 kg of aluminum hydroxide and continue to heat up to 230°C; then add 8 kg of 300# gasoline within 5 minutes , 12 kilograms of dodecylbenzene, 2 kilograms of aluminate coupling agent (H-2), 3 kilograms of dibutyl ester plasticizer and 5 kilograms of di-salt stabilizer (dibasic lead phosphite); Still, make flame retardant of the present invention.

[0017] During the production process, since various additives such as coupling agents, gasoline, dodecylbenzene, plasticizers and stabilizers volatilize or decompose at high temperatures, the main active ingredients of the finished product after testing are The contents of white carbon black, antimony trioxide and aluminum hydroxide are 45-70%, 15-40% and 15-40% respectively. The appearance is off-white powder, the particle size is above 320 mesh, and the density is 2.3-2.35g / cm (the average v...

Abstract

The invention provides a low-cost inorganic silicon-based flame retardant and a production method thereof which does not affect the physical and mechanical properties of the product. The flame retardant mainly contains white carbon black, aluminum hydroxide and antimony trioxide. This flame retardant does not damage the physical and mechanical properties of polymer products, has good compatibility, particularly strong affinity, is non-toxic, has a long-lasting flame retardant effect, and has a production cost much lower than that of organic flame retardants.

Description

technical field [0001] The invention relates to a flame retardant, in particular to an inorganic silicon-based flame retardant used in the processing of mine flame-retardant conveyor belts or cable materials. Background technique [0002] Flame retardant is one of the most consumed additives in plastic processing, and it also has broad application prospects in synthetic fibers, rubber, coatings, etc. At present, the existing flame retardants on the market are mainly divided into two types: inorganic and organic. Among them, although the price of inorganic flame retardants is low, it affects the processing performance and physical and mechanical properties of products; although organic flame retardants affect the processing performance of products And physical properties have little effect, but its cost is high, and generally contains toxic substances (such as halogens) that are harmful to the human body. At present, hundreds of products of bromine, chlorine, phosphorus, bor...
