Description
Technical field: the invention belongs to petrochemical complex and technological development field, relate to a kind of tubeless radial assembling lubricating fluid.
Background technology: tire is one of vitals of various Motor vehicles such as automobile, and the quality of its performance can directly influence the performance of vehicle.Along with the fast development of transport by road, more strictnesses and harsh requirement are proposed vehicle tyre.These functional requirements can reduce the following aspects basically: security, control stability, travelling, riding comfort and energy saving economy etc.
China's " the Seventh Five-Year Plan " planning has stipulated that clearly automotive industry is the mainstay industry in the national economic development, causes the tire industry of China also to need correspondingly accelerated development.Domestic tire industry with abroad compare, no matter from kind to gap is all bigger qualitatively.The tire industry of China development at present is to be center and model change to improve the quality of products, and the trend of regeneration product is radial-ply tyreization, tubelessization and flattening.
The car range that Aeolus-Citron Automobile Company Ltd is produced, wheel adopts more advanced free from inflatable inner tube radial, though the tubeless radial has lot of advantages, but its hardness height, the process that the tyre and rim that this hardness is high is assembled together is the comparison difficulty, so necessary brushing one deck oilness is good in assembling process, and to rubber for tire and the good lubricant of wheel rim paint face adaptability.Otherwise, not only production efficiency be can influence, and tyre surface infringement and rim deformation easily caused, influence the work-ing life of tire, in the time of seriously even can have influence on running safety.Domestic still do not have the sale of this tire assembling lubricant agent special at present, though Aeolus-Citron Automobile Company Ltd uses the tire assembling lubricant of French import can satisfy matching requirements always, the source of goods is difficult to tissue, and procurement cycle is long, and the import lubricant costs an arm and a leg.
Summary of the invention: the present invention is in order to solve the problem of tubeless radial hardness height, assembling difficulty, a kind of tire assembling lubricating fluid has been proposed, it is characterized in that, described tire assembling lubricating fluid is to add thickening material, tensio-active agent, several additives of sterilant to mix in the aqueous solutions of polymers of fatty compounds and derivative thereof, and thickening material is selected acrylate copolymer, propylene glycol alginate for use; Tensio-active agent is selected alkylphenol polyoxyethylene, Oleum Cocois alkylolamide for use; Sterilant is selected three red oil, 2-bromo-2-nitro propylene glycol, mould inhibitor CY-1 for use; Its component weight percent content is:
Component concentration
The aqueous solutions of polymers 85～87% of fatty compounds and derivative thereof
Thickening material 12～13%
Tensio-active agent 0.5～1%
Sterilant 0.5～1%
This tire assembling lubricating fluid, in application process, the oilness of product is good, saves time, laborsaving, can satisfy the requirement of tubeless radial assembly technology fully.Good to rubber for tire and wheel rim paint face adaptability, after the brushing, colourless, the no cracked and obscission of the lubricant film that is become.
Description of drawings: Fig. 1 is the configuration process flow sheet of tire assembling lubricating fluid of the present invention.
Embodiment: tire assembling lubricating fluid is that the aqueous solution adds additives such as thickening material, tensio-active agent and sterilant and mixes in the aqueous solutions of polymers of fatty compounds and derivative thereof, and wherein the aqueous solutions of polymers of fatty compounds and derivative thereof comprises polyoxyethylene glycol, polyvinyl alcohol, polyacrylamide etc.; Thickening material is acrylate copolymer, propylene glycol alginate, and wherein acrylate copolymer comprises sodium polyacrylate, calcium polyacrylate (CPA), polyacrylic acid; Tensio-active agent is alkylphenol polyoxyethylene, Oleum Cocois alkylolamide, and wherein the Oleum Cocois alkylolamide comprises mixture (6501), the dodecanolyacylamine phosphoric acid ester (6503) of dodecyl diglycollic amide, dodecyl diglycollic amide and diethanolamine; Sterilant can be selected three red oil, 2-bromo-2-nitro propylene glycol, mould inhibitor CY-1 for use.
Because viscosity and lubricity have certain relation, select the experimental result statistics of thickening material to see Table 1 thickening material solubility experiment result:
Table 1 thickening material solubility experiment result
