Description
Technical field
The present invention relates to a kind of fire-fighting rubber composition for footwear and preparation method thereof.
Background technology
In general, rubber composition for footwear must be able to be made wearer's body weight, the load that bears the motion generation and impact intensity of force, improves comfort level, security and the anti-skid of shoes.
The fire-fighting footwear are to provide the firefighter and wear in the severe environment such as fiery residence, the special type protection footwear that protection both feet and shank escape injury.What the fire fighter was engaged in is the work that certain risk is arranged, and the protection footwear of its dress need to possess waterproof simultaneously, heat insulationly, anti-skidding, anti-pierce through, anti-ly pound, side and bear building-up close the performances such as firm, wear-resisting and anti-complications.
Because the scene of a fire structure of matter occurs constantly to change, especially in the scene of a fire existed at a large amount of acid, alkali and oily substance, gap based on the oil resistant of rubber own, acid-proof alkaline, make the barrier propterty of the fire-fighting footwear of quality of rubber materials reduce rapidly, accelerate the damage of footwear boots so that do not reach the effect of protection, cause the firemen to be burnt by acid-base material, affect the process of fire-fighting work.Therefore, the fire-fighting footwear also should have the performance of oil resistant, acid and alkali-resistance, can meet the requirement under the complex environment of the scene of a fire.
CN102924772A discloses a kind of fire-fighting rubber composition for footwear and preparation method thereof.The basic glue of described rubber combination mainly is comprised of the chloroprene rubber of 90～100 weight parts and the cis-1,4-polybutadiene rubber of 0～10 weight part, also comprises other Synergist S-421 95s.By each component by the mixing rubber combination that obtains of formula ratio.This invention is by selecting rational basic glue, fire retardant and other Synergist S-421 95; make the fire-fighting rubber composition for footwear finally made there are good wear resistance, oil resistant, acid and alkali-resistance, flame retardant resistance and insulativity etc.; improved to a great extent the indices of fire-fighting footwear, the fire fighter has been played in severe environment to better provide protection.
Summary of the invention
For the deficiencies in the prior art, one of purpose of the present invention is to provide a kind of fire-fighting rubber composition for footwear, and it has the fire-fighting rubber composition for footwear of excellent oil resistant, acid and alkali-resistance, wear-resisting, fire-retardant and insulativity.

Preferably, described fire-fighting rubber composition for footwear comprises following raw material by weight:
Described fire retardant is selected from the mixture of any one or at least two kinds in chlorinated paraffin-70, antimonous oxide, zinc borate, aluminium hydroxide or phosphoric acid ester.Described mixture is the mixture of chlorinated paraffin-70 and antimonous oxide for example, the mixture of zinc borate and aluminium hydroxide, the mixture of aluminium hydroxide and phosphoric acid ester, the mixture of chlorinated paraffin-70, antimonous oxide, zinc borate and aluminium hydroxide, the mixture of chlorinated paraffin-70, antimonous oxide, zinc borate, aluminium hydroxide and phosphoric acid ester.
Activating agent for rubber can promote sulfuration, activation and the reinforcement anti-aging effect of rubber, can strengthen sulfidation, reaches stability, processing safety raising, the decrease fraction defective, improve rubber item resistance to tearing, wear resistance, simultaneously, can improve anti-aging, the anti-crawl agentdefiection fragility energy of rubber product.Stearic acid selected by promoting agent of the present invention or/and Zinic stearas all can commercially availablely obtain.Two kinds of promoting agents can be used alone, and also can mix use, mix to use to obtain obvious synergy.
Described strengthening agent is selected from the mixture of a kind of in carbon black N234, carbon black N220 or carbon black N330 or at least two kinds, described mixture is the mixture of carbon black N330 and carbon black N220 for example, the mixture of carbon black N330 and carbon black N234, the mixture of carbon black N330, carbon black N220 and carbon black N234.Described carbon black N234 is fine intermediate super abrasion furnace black high structure, and carbon black N330 is high abrasion furnace black(HAF), and carbon black N220 is that height is stretched medium super abrasion furnace black surely.Carbon black can make rubber have high wear resistance, tensile strength etc. as strengthening agent.Association reaction between carbon black and rubber is the fundamental cause of carbon black to reinforcing rubber.At first the wetting carbon black of the rubber molecule of viscous state, then well be adsorbed on carbon blacksurface, forms physical bond.Carbon black of the present invention is the nano level carbon black, nano level carbon black uneven surface has a large amount of edges and fin, the active site of these high surface energies causes, with polymkeric substance, very strong physics/physics chemical action is arranged, the interaction of polymer surfaces is also strengthened thereupon, so just increased the contacted probability of polymer segment and carbon blacksurface, the black-reinforced effect strengthens.Three kinds of carbon blacks can be used alone, and also can mix use, mix to use to obtain obvious synergy.
In order to reduce curing temperature, shorten curing time, improve the physical and mechanical properties of sulfide, during sulfur cross-linking, must add vulcanization accelerator.Promotor of the present invention is selected from the mixture of a kind of in accelerant CZ, Vulcanization accelerator TMTD, vulkacit D, accelerator DZ or accelerant NOBS or at least two kinds.Described mixture is the mixture of accelerator DZ and accelerant NOBS for example, the mixture of vulkacit D and Vulcanization accelerator TMTD, the mixture of accelerant CZ and accelerant NOBS, the mixture of accelerator DZ and vulkacit D, the mixture of Vulcanization accelerator TMTD and accelerant CZ, the mixture of accelerant NOBS, accelerator DZ and vulkacit D, the mixture of Vulcanization accelerator TMTD, accelerant CZ and accelerant NOBS, the mixture of accelerator DZ, vulkacit D, Vulcanization accelerator TMTD and accelerant CZ.Five kinds of vulcanization accelerators can be used alone, and also can mix use, mix to use to obtain obvious synergy.
Degradation with aging, can occur in the impact of the envrionment conditionss such as rubber is heated in prolonged application, oxygen, light.Be heated in process of production simultaneously, the shearing action of mechanical workout, can occur to decompose and separating phenomenon.Therefore, in order to prevent the aging of styrene-butadiene rubber(SBR) and to decompose, need add anti-aging agent.Preferably, described anti-aging agent is selected from the mixture of a kind of in anti-aging agent RD, antioxidant 4010NA, antioxidant 4020, antioxidant D NP or antioxidant MB or at least two kinds.Described mixture is the mixture of antioxidant MB and antioxidant D NP for example, the mixture of antioxidant 4020 and antioxidant 4010NA, the mixture of anti-aging agent RD and antioxidant MB, the mixture of antioxidant D NP and antioxidant 4020, the mixture of antioxidant 4010NA, anti-aging agent RD, antioxidant MB and antioxidant D NP, the mixture of antioxidant MB, antioxidant D NP, antioxidant 4020, antioxidant 4010NA and anti-aging agent RD.Anti-aging agent RD: 2,2,4-trimethylammonium-1,2-dihyaroquinoline polymer; Antioxidant D NP:N, N-bis-(betanaphthyl) Ursol D; Antioxidant MB: 2-mercaptobenzimidazole, antioxidant 4010NA: N-sec.-propyl-N ' phenyl-Ursol D, antioxidant 4020: N-(1, the 3-dimethylbutyl)-N'-diphenyl-para-phenylene diamine, five kinds of anti-aging agent can be used alone, also can mix use, mix use to obtain obvious synergy, and can add and there is synergistic stablizer.
Preferably, the parts by weight of described anti-aging agent are 1～4, are for example 1.2,1.4,1.6,1.8,2,2.2,2.4,2.6,2.8,3,3.2,3.4,3.6 or 3.8.
