Described vulcanizing agent is the SULPHUR POWDER of more than fineness 200 order.
As the detailed statement to foregoing of the present invention, particular content is as follows:
Use the paracril N230S of medium acrylonitrile content in the present invention, adopt at the bottom of the obtained glue of the paracril of medium acrylonitrile content and there is good electroconductibility and oil-proofness;
Use anti-aging agent 2-mercaptobenzimidazole (antioxidant MB) in the present invention, good protective effect can be played to the thermo-oxidative ageing, Weather etc. of rubber soles; Use anti-aging agent N-sec.-propyl N '-diphenyl-para-phenylene diamine (antioxidant 4010NA), to the ozone-resistant aging resistance, the effect of being very helpful of flex cracking resistance performance that improve rubber soles; Antioxidant MB and 4010NA with the use of, to preventing rubber thermal ageing, oxygen aging, photoaging, dynamic fatigue and resisting that the catalysis of the poisonous metal such as copper, manganese is aging efficient synergy.
In the present invention, the graphitized carbon black of use is Shawinigan black.This is the electroconductibility in order to increase cross-linked rubber, improves into the static resistance of footwear.The addition of Shawinigan black is 35-45 part, because the calendering process of Shawinigan black is bad, exceed this amount, the processibility of rubber unvulcanizate can serious deterioration.On the contrary, if use level is lower than 35-45 part, then the electroconductibility at the bottom of glue can not reach requirement.
The use of accelerator dibenzothiazyl disulfide (altax), can improve rubber vulcanization speed and state of vulcanization in the present invention, and because thiazole accelerator plays sulphur comparatively early, vulcanization rate is fast, and state of vulcanization is high, so vulcanizating glue physical performance is good.
Use promotor sulphenamide (i.e. accelerant CZ) and tetramethyl-thiuram disulfide (i.e. Vulcanization accelerator TMTD) as secondary accelerator in the present invention.The use of these two kinds of promotor, plays activation for altax, can improve vulcanization rate and the state of vulcanization of sizing material further, improve the physicals of cross-linked rubber.
In the present invention, the altax of 1-1.5 weight part, can ensure that cross-linked rubber has suitable state of vulcanization.If exceed this number, the vulcanization rate of sizing material can be too fast, unfavorable to the safety in production of sizing material, also increases the danger of cross-linked rubber bloom; If lower than this number, the state of vulcanization of cross-linked rubber can be caused not high, and rubber unvulcanizate vulcanization rate is partially slow, be not suitable for using on rubber dual-density shoe boots production line, the physicals of its cross-linked rubber also can decline, and specifically, the possibility becoming wear-resisting, the folding quality of footwear not to reach requirement strengthens.
Other two kinds of accelerant CZs and TMTD in the present invention, belong to secondary accelerator, use level is less, and major function plays the effect to primary accelerator activation, and object improves the state of vulcanization of cross-linked rubber further, improves the physicals of cross-linked rubber.In the present invention, the use level of accelerant N-cyclohexyl-2-[4-morpholinodithio sulphenamide (i.e. accelerant CZ) is 0.5-0.8 part, because the guarantor that accelerant CZ is a kind of rear acting type enters agent, as a kind of secondary accelerator, primary accelerator DM can be activated, to improve the effect of primary accelerator DM.As secondary accelerator, use level is that the half of primary accelerator is comparatively suitable, so determine that the suitable use level of accelerant CZ is 0.5-0.8 part.
In the present invention, the use level of accelerant disulfide tetra methylthiuram (being Vulcanization accelerator TMTD) is 0.3-0.6 part.Because Vulcanization accelerator TMTD is the promotor that a kind of activity is stronger, be used alone, its vulcanization rate is fast, and state of vulcanization is high.As secondary accelerator, its use level is unsuitable large, and in the present invention, the use level of Vulcanization accelerator TMTD is lower than the use level of accelerant CZ, is 0.3-0.6 part.Mainly control the vulcanization rate of rubber unvulcanizate.If the use level of Vulcanization accelerator TMTD is lower than this, then do not have the activation to primary accelerator DM, if higher than this use level, the vulcanization rate of rubber unvulcanizate can be made again too fast, be not suitable as primer and use on rubber dual density production line.
In the present invention, the use of the solid grand resin of horse of tackifier, mainly increases the autohension of sizing material, improves the explained hereafter performance of rubber unvulcanizate, and then improve the qualification rate of finished product.
In the present invention, the use level of plasticizer DOP is 15-25 part, and the effect of softening agent mainly controls the hardness of sizing material, improves the operating procedure performance of sizing material, is convenient to processing.Because the hardness at the bottom of rubber dual-density shoe boots glue is generally ShoreA about 55 degree, so in the present invention, use level 15-25 part of plasticizer DOP is proper.If exceed this amount, after footwear last pressure terminates, one-tenth footwear hardness can be on the low side, nonconforming.On the contrary, if plasticizer loading is lower than 15-25 part, can cause rubber compounding difficulty, the dispersion of other compounding ingredient is bad, and cross-linked rubber hardness is higher, becomes the hardness at the bottom of footwear glue also nonconforming.
In the present invention, the use of vulcanizing agent, rubber unvulcanizate can be made chemical reaction can to occur after being heated, vulcanization crosslinking, and rubber is transformed into build macromole from linear macromolecule, and then becomes the cross-linked rubber having stable chemical state.The parts by weight of vulcanizing agent are 1.5-1.7, if higher than this number, have following two disadvantages:
A). cross-linked rubber state of vulcanization can be made higher, and cross-linked rubber hardness is nonconforming;
B). the vulcanization rate of rubber unvulcanizate can be made fast, and sulfuration is too short for inductive phase, and sizing material does not have enough safety in production, and rubber dual-density shoe boots production line cannot normally be produced;
If but lower than this number, have following two disadvantages:
A). vulcanization rate can be caused excessively slow, normally can not produce on rubber dual-density shoe boots production line;
B). cross-linked rubber state of vulcanization can be made too low, and vulcanizating glue physical performance does not reach requirement, and product shoes is nonconforming.
Limit, in described foaming layer rubber layer raw material as another kind of the present invention
A) described paracril is the paracril of low acrylonitrile content, N240S;
B) consisting of of the promoting agent described in: 4 ~ 5 parts, zinc oxide, stearic acid 2 ~ 3 parts;
C) anti-aging agent described in is: 0.8 ~ 1.2 part, heterocyclic anti-aging agent, amines antioxidants 0.8 ~ 1.2 part;
D) promotor described in is: thiazole accelerator 1.0 ~ 1.5 parts, sulfenamide type accelerators 0.5 ~ 0.8 part, thiuram type accelerator 0.5 ~ 0.8 part.
As the further restriction of above-mentioned restriction, described carbon black is high abrasion furnace carbon black N330;
Described heterocyclic anti-aging agent chemical name is 2-mercaptobenzimidazole; Described amines antioxidants is anti-aging agent N-sec.-propyl N '-diphenyl-para-phenylene diamine;
Described thiazole accelerator is dibenzothiazyl disulfide; Described sulfenamide type accelerators is N-cyclohexyl-2-[4-morpholinodithio sulphenamide; Described thiuram type accelerator is tetramethyl-thiuram disulfide;
Described softening agent is dioctyl phthalate (DOP); Described tackifying resin is the solid grand resin of horse;
Described vulcanizing agent is the SULPHUR POWDER of more than fineness 200 order; Described whipping agent is two benzol sulfohydrazide ethers.
State in detail as to foregoing of the present invention, particular content is as follows:
Use the paracril of low acrylonitrile content in the present invention, model is N240S, mainly because in rubber dual-density shoe boots, foaming layer rubber layer will with bottom rubber layer covulcanization, namely both in conjunction with problem, owing to employing conductive nail in the present invention, so no longer consider the electroconductibility of rubber in foaming layer rubber layer, relative to the paracril of medium acrylonitrile content, the vulcanization rate of the paracril of low acrylonitrile content will obviously be accelerated, the good manufacturability of sizing material, be adapted at using in foaming layer rubber layer, and they all belong to a class rubber together, so, as long as control the vulcanization rate of sizing material well, good covulcanization should be had between the two.
Use anti-aging agent 2-mercaptobenzimidazole (i.e. antioxidant MB) in the present invention, good protective effect can be played to the thermo-oxidative ageing, Weather etc. of rubber soles; Use anti-aging agent N-sec.-propyl N '-diphenyl-para-phenylene diamine (i.e. antioxidant 4010NA), to the ozone-resistant aging resistance, the effect of being very helpful of flex cracking resistance performance that improve rubber soles; Antioxidant MB and 4010NA with the use of, to preventing rubber thermal ageing, oxygen aging, photoaging, dynamic fatigue and resisting that the catalysis of the poisonous metal such as copper, manganese is aging efficient synergy.
In the present invention, the carbon black used in foamed glue is high abrasion furnace carbon black N330, this is because in the present invention, the rear heel of footwear boots have employed metallic conduction nail by the short circuit of foaming layer rubber, and foaming rubber layer no longer needs to consider electroconductibility.Only require to a certain degree to carbon black reinforcing.
The use of accelerator dibenzothiazyl disulfide (altax), can improve rubber vulcanization speed and state of vulcanization in the present invention, and because thiazole accelerator plays sulphur early, vulcanization rate is fast, and state of vulcanization is high, so vulcanizating glue physical performance is good.
Use promotor sulphenamide (accelerant CZ) and tetramethyl-thiuram disulfide (Vulcanization accelerator TMTD) in the present invention.The use of these two kinds of promotor, plays activation to primary accelerator DM.Vulcanization rate and the state of vulcanization of sizing material can be improved further, improve the physicals of cross-linked rubber.
In the present invention, the altax of 1-1.5 parts by weight, can ensure that cross-linked rubber has suitable state of vulcanization.If exceed this number, the vulcanization rate of sizing material can be too fast, unfavorable to the safety in production of sizing material, also increases the danger of cross-linked rubber bloom; If lower than this number, the state of vulcanization of cross-linked rubber can be caused not high, vulcanization rate is partially slow, and the possibility of owing sulphur strengthens, the physicals of cross-linked rubber declines, and can have influence on the bondability of foamed glue and upper of a shoe.
Other two kinds of accelerant CZs and TMTD in the present invention, belong to secondary accelerator, use level is less, and major function plays the effect to primary accelerator activation, and object improves the state of vulcanization of cross-linked rubber further, improves the physicals of cross-linked rubber.
In the present invention, the use level of accelerant N-cyclohexyl-2-[4-morpholinodithio sulphenamide (accelerant CZ) is 0.5-0.8 part, because the guarantor that accelerant CZ is a kind of rear acting type enters agent, as a kind of secondary accelerator, primary accelerator DM can be activated, to improve the effect of primary accelerator DM.As secondary accelerator, use level is the half best results of altax, so determine that the suitable use level of accelerant CZ is 0.5-0.8 part.
In the present invention, the use level of accelerant disulfide tetra methylthiuram (Vulcanization accelerator TMTD) is 0.5-0.8 part.Because Vulcanization accelerator TMTD is the promotor that a kind of activity is stronger, if be used alone, its vulcanization rate is very fast, and state of vulcanization is higher.As secondary accelerator, its use level is unsuitable excessive, in the present invention, in foamed glue, the use level of Vulcanization accelerator TMTD is larger than the use level of Vulcanization accelerator TMTD in primer, reason is on rubber dual-density shoe boots production line, the curing time of foaming layer rubber is shorter than the curing time of bottom rubber, and thus, the vulcanization rate of foamed glue must be faster than the vulcanization rate of primer.If the use level of Vulcanization accelerator TMTD is lower than this, the vulcanization rate of rubber unvulcanizate can be made again partially slow, be not suitable for using on rubber dual density production line.
In the present invention, the effect of plasticizer DOP mainly reduces the hardness of sizing material, improves the operating procedure performance of sizing material.Because the basic hardness of rubber dual-density shoe boots rubber pange glue is generally about ShoreA40 degree, so in the present invention, use level 20-30 part of plasticizer DOP is proper.If exceed this amount, rubber unvulcanizate can too soft, and one is unfavorable for that workman refines glue, and two come after footwear last pressure terminates, and one-tenth footwear hardness can be on the low side, nonconforming.On the contrary, if plasticizer loading is lower than 20-30 part, become the hardness of footwear foaming layer rubber also nonconforming.
In the present invention, in foaming rubber layer, the use level of vulcanizing agent is 2.0-2.2 part, larger than the use level of bottom rubber layer.Mainly in order to improve the vulcanization rate of sizing material, be applicable to the actual requirement on rubber dual-density shoe boots production line.
