Abstract
The invention provides a kind of low-cost inorganic silicon series fire retardant which won't affect the physical and machine capability of the produce and its producing method. The fire retarder mainly contains white carbon black, aluminum hydroxide and stibium trioxide. This kind of fire retarder won't damage the physical and machine capability of the polymer produce, its mutual solubility is good, its appetency is especially strong, it is innoxious, and has lasting fire retarding effect. Besides its producing cost is much low than organ fire retarder.
Description
Technical field
The present invention relates to a kind of fire retardant, particularly a kind of inorganic silicon flame retardant that is used for mining flame-retardant conveying belt or CABLE MATERIALS processing.
Background technology
Fire retardant is one of auxiliary agent that consumption is maximum in the plastic working, also has broad application prospects at aspects such as synthon, rubber, coating.Existing in the market fire retardant mainly is divided into inorganic and organic two types, though wherein the inorganic combustion inhibitor price is low, it influences the processing characteristics and the physical and mechanical properties of goods; Though organic fire-retardant is little to the processing characteristics and the physicals influence of goods, its cost height, and generally contain harmful toxicant (as halogen).The present bromine that uses in the world, chlorine, phosphorus, boron, antimony hundreds of product of totally five big classes combustion resistance agent all have certain toxin in varying degrees.In worldwide all the explicit order time limit use the brominated flame retardant product, other type fire retardant also will be substituted by nontoxic fire retardant.
At the above-mentioned shortcoming of existing fire retardant, the applicant has invented a series of inorganic silicon flame retardants through unremitting effort, is 200510053434.9 patent of invention as the application number of having applied for to State Intellectual Property Office before the applicant.This eka-silicon system combustion resistance agent is not halogen-containing, and effect is big, and use range is wide.The blank of silicon-series five-retardant in the world wide, another branch of having started flame retardant products have been filled up in their appearance.Along with producing the immense success that is obtained in the middle of the use, present this silicon-series five-retardant has caused the fire-retardant colleague's of boundary in the whole world great attention and approval.
Summary of the invention
One aspect of the present invention provides a kind of goods physical and mechanical properties and cheap inorganic silicon flame retardant of not influencing.
Inorganic silicon flame retardant of the present invention mainly comprises: white carbon black: 45%-70%; Antimonous oxide: 15%-40%; Aluminium hydroxide 15%-40%.
The present invention provides a kind of production method of above-mentioned inorganic silicon flame retardant on the other hand.
This production method is: the white carbon black of 45-70 part is put into reactor, be warming up to 120 ℃-190 ℃; Add 15-40 part antimonous oxide and 15-40 part aluminium hydroxide again; After being warming up to 150 ℃-230 ℃, in 3-5 minute, add 5-8 part gasoline, 10-12 part dodecylbenzene, 1-2 part coupling agent, 1-3 part softening agent and 3-5 part stablizer respectively.
White carbon black of the present invention is not particularly limited, and can adopt any commercially available white carbon black; Coupling agent also is not particularly limited, as adopting silane coupling agent, titanate coupling agent or aluminate coupling agent etc.; Gasoline preferably adopts high-grade gasoline, as adopting 120-300# gasoline; Softening agent also is not particularly limited, and for example can adopt dioctyl ester or dibutylester softening agent etc.; Stablizer also is not particularly limited, and for example can adopt stablizers such as three salt or disalt.
Silicon-series five-retardant of the present invention does not damage the physical and mechanical properties of polymer product, and promptly polymkeric substance is after fire-retardant processing, and its original physicals does not degenerate, and does not particularly reduce heat-drawn wire, physical strength and electric property etc.; Lasting and the production cost of flame retardant effect is far below organic fire-retardant.
Embodiment
Respectively (ball milling) ground evenly to standby more than 325 orders in the dry back of white carbon black, aluminium hydroxide and antimonous oxide (purity is not less than 90%, preferably is not less than 99%);
Embodiment 1
45 kilograms of white carbon blacks are put into reactor, be warming up to 120 ℃; Add 15 kilograms of antimonous oxides and 40 kilograms of aluminium hydroxides then, continue to be warming up to 150 ℃; Then in 3 minutes, add 5 kilograms of 120# gasoline, 10 kilograms of dodecylbenzenes, 1 kilogram of silane coupling agent (KH-550), 1 kilogram of dioctyl ester softening agent and 3 kilogram of three salt stabilizing agent (lead sulfate tribasic) respectively; Go out still after the cooling, make fire retardant of the present invention.
Embodiment 2
70 kilograms of white carbon blacks are put into reactor, be warming up to 150 ℃; Add 15 kilograms of antimonous oxides and 15 kilograms of aluminium hydroxides then, continue to be warming up to 190 ℃; Then in 4 minutes, add 6 kilograms of 200# gasoline, 11 kilograms of dodecylbenzenes, 1.5 kilograms titanate coupling agent (CS-101), 2 kilograms of dibutylester softening agent and 4 kilogram of two salt stabilizing agent (dibasic lead phosphite) respectively; Go out still after the cooling, make fire retardant of the present invention.
Embodiment 3
45 kilograms of white carbon blacks are put into reactor, be warming up to 190 ℃; Add 40 kilograms of antimonous oxides and 15 kilograms of aluminium hydroxides then, continue to be warming up to 230 ℃; Then in 5 minutes, add 8 kilograms of 300# gasoline, 12 kilograms of dodecylbenzenes, 2 kilograms of aluminate coupling agents (H-2), 3 kilograms of dibutylester softening agent and 5 kilogram of two salt stabilizing agent (dibasic lead phosphite) respectively; Go out still after the cooling, make fire retardant of the present invention.
In the production process, because the additive of various modifying functions such as coupling agent, gasoline, dodecylbenzene, softening agent and stablizer be volatilization or decomposition mostly at high temperature, the main active ingredient of back gained finished product is white carbon black, antimonous oxide and aluminium hydroxide after testing, and content is respectively 45-70%, 15-40% and 15-40%.Outward appearance is a pale powder, and granularity is more than 320 orders, and density is 2.3-2.35g/cm (mean value of white carbon black density and antimonous oxide density); Water content is not higher than 0.5%.
This product advantage is as follows:
1, efficient: as to stick with paste in the body prescription at the PVC fire retarding conveying band, only need to use this a kind of product 20-25 part (ratio of total umber), can make the flame retardant effect of product reach the MT147 of Ministry of Coal Industry-92 standard.
2, good dispersity: in macromolecular material, be uniformly dispersed.
3, macromolecular material is had no adverse effects: this product is little to the physical and chemical performance influence of macromolecular material, and has certain strengthening action.For example can improve the density of fire retarding conveying band integral body.
