The present invention is a kind of tire tread glue of non-oxidation zinc, all adds zinc oxide in existing tread rubber.Can discharge zinc in environment in the production of tire, use and removal process, and the release of zinc can to HUMAN HEALTH, especially cause disadvantageous effect to hydrobiont and can polluted underground water.In the tire tread glue formulation of non-oxidation zinc of the present invention, in massfraction: every 100 parts of rubber, add 2 ~ 4 parts of quaternary ammonium salts, add carbon black, stearic acid, accelerant CZ, sulphur, antioxidant 4010NA simultaneously.Adopt base rubber to be based on styrene-butadiene rubber(SBR), natural rubber, cis-1,4-polybutadiene rubber and blend compounds thereof; Adopt quaternary ammonium salt to be cetyl trimethylammonium bromide, palmityl trimethyl ammonium chloride or Cetyltrimethylammonium bromide, octadecyl trimethyl ammonium chloride.The present invention replaces zinc oxide with quaternary ammonium salt, for activating promotor, reducing ash content and polluting, environmental protection more.
Description
Technical field
The present invention relates to a kind of new vulcanization process, replace zinc oxide with quaternary ammonium salt, as activation promotor, obtain good performance, avoid zinc oxide and pollute.
Background technology
Recently, reduce the consumption of zinc oxide in rubber size and become an important research topic, because soluble zinc compound is harmful to aquatic organism.At rubber item, in the especially production of tire, use and removal process, zinc can be discharged in environment.Scrap tire rubber particle used when zinc in underground water may derive from the rubber dust of tire wear and build athletic ground.The release of zinc to HUMAN HEALTH, especially can cause disadvantageous effect to hydrobiont.In European Commission 2400/73/EC instruction, zinc oxide is divided into " to bad environmental ", risk predicate be R50/53 " toxic to aquatic organism, long-term harmful effect [1] can be produced to water surrounding.”
China in 2012 produces 8.92 hundred million, tire, is 2% calculating, can produces 35.68 ten thousand tons of zinc oxide, be that 1.6mg/L calculates, can pollute the water source of 2230 billion cubic meters by the water solubility of zinc oxide in waste material by zinc oxide mass ratio.And the natural resources recharge of the annual fresh groundwater of China is about 8840 billion cubic meters, fresh groundwater can production of resources be annual 3530 billion cubic meters.In junked tire, zinc oxide has caused very serious consequence to the pollution at water source.So reducing the consumption of zinc oxide in sizing material is our inevitable choice.
Quaternary ammonium salt is the important cats product of a class, is to be reacted by tertiary amine and alkylating agent and obtain, and this compounds is applied widely.Quaternary ammonium salt and other types surfactant compatibility good, and there is good emulsifying, wetting, solubilising, washing, sterilization, softness, help dye, fixation, a series of performance such as antistatic, except being used widely at chemical industry and other industrial circles, be also more and more subject to people's attention in antibacterial and sterilization.Quaternary ammonium salt is of a great variety, different according to its structure, can be divided into single long chain quaternary, two long chain quaternary, two long-chain bi-quaternary ammonium salt and other quaternary ammonium salts.Single long chain quaternary common are cetyl trimethylammonium bromide, Cetyltrimethylammonium bromide etc. [2].
The present invention relates to a kind of Novel vulcanization method that quaternary ammonium salt directly replaces zinc oxide.
Summary of the invention
Vulcanization accelerator decomposes to the object of the invention is to replace zinc oxide to promote with quaternary ammonium salt, obtains a kind of new vulcanization process, avoids zinc oxide to pollute.
The tire tread glue of a kind of Novel non-oxidation zinc that the present invention relates to, is characterized in that:
In tire tread glue formulation, in mass fraction: every 100 parts of rubber, add 2 ~ 4 parts of quaternary ammonium salts, replacing zinc oxide with quaternary ammonium salt, for activating promotor, removing all zinc oxide.
Adopt base rubber to be based on styrene-butadiene rubber(SBR), natural rubber, cis-1,4-polybutadiene rubber and blend compounds thereof.
Adopt quaternary ammonium salt to be cetyl trimethylammonium bromide, palmityl trimethyl ammonium chloride, Cetyltrimethylammonium bromide or octadecyl trimethyl ammonium chloride.
Beneficial effect of the present invention
(1) the present invention's quaternary ammonium salt replaces zinc oxide, regulates the curability of sizing material, promotes promotor decomposition, reduces ash content and pollutes, environmental protection more.
(2) technique involved in the present invention is simple, is easy to industrialization.

Fill a prescription by table 1; styrene-butadiene rubber(SBR) 1502/ natural rubber/cis-1,4-polybutadiene rubber consumption (three's mass ratio: 10/80/10), carbon black N330 consumption 30 parts, zinc oxide dosage 0 part, cetyl trimethylammonium bromide consumption 3 parts be mixing; melting temperature is 50 DEG C; curing temperature is 145 DEG C, and curing time is 1h that is 100 parts.Then the curability of sizing material at testing 145 DEG C.145 DEG C of vulcanization curves of sample are as shown in curve (a) in Figure 10, and 145 DEG C of vulcanization curves of reference are as shown in curve (b) in Figure 10; Its cross-linked rubber curability and physical and mechanical properties are in table 11.
Table 11 quaternary ammonium salt is to styrene-butadiene rubber(SBR)/natural rubber/cis-1,4-polybutadiene rubber blend compounds performance impact
From table 11, result can be found out: compared with reference, the T containing 3 parts of quaternary ammonium salt sizing materials
10, T
90all shorten, improve vulcanization rate; And its stress at definite elongation, tensile strength, tear strength are all improved, illustrate that quaternary ammonium salt can improve its mechanical property in styrene-butadiene rubber(SBR)/natural rubber/cis-1,4-polybutadiene rubber paralled system.
