Abstract
The application discloses a phosphate additive, which has the following structural formula:wherein n is 1 The range of the value of (2) is between 12 and 18; the group R1 is implemented as a polyoxyethylene Ether (EO) -containing polymer; r is monoethanolAmine and formaldehyde reaction products.
Description
Technical Field
The invention relates to an additive, in particular to a phosphate additive.
Background
The metal is dry friction in the rolling process, and the corresponding friction coefficient is large. Under the condition of high down force, deformation and friction heat are generated in a roll gap area, if necessary lubrication and cooling are not introduced, the service life of the roll is shortened, and the surface of the rolled aluminum alloy is damaged.
Therefore, during the aluminum rolling process, a lubricant is often properly added for lubrication and cooling purposes. The organic acid and the ester substance in the lubricating additive can provide good lubricating capability. Especially, phosphate is used as the main material, so that good extrusion lubrication can be provided in a roll gap area.
The phosphate is one of extreme pressure antiwear agents, and has good lubricating property, high flash point and natural point. Specific mention is made in the following documents: liu Xianjie, chen Ligong, cao Shuhan, etc. Phosphate ester lubricating oil additives. SYNTHETIC LUBRICANTS,2013, 40 (3): 1672-4364 Qiao Yulin, fang Xuejing, dang Hongyu. Development dynamics of sulfur-phosphorus extreme pressure antiwear additive [ J ]. Lubrication and sealing, 1994 (6): 55-59.
It is important to note that at present, phosphoric acid esters tend to cause blackening of the surface of aluminum products due to fine aluminum powder when used as a lubricant. According to published patents or literature, and in combination with current commercial technology, we can see that current phosphates fall into two main categories, specifically: neutral phosphate esters and acidic phosphate esters.
Among neutral phosphates, tricresyl phosphate (TCP) has been widely used in the rolling industry, and its good extrusion lubricating ability does not cause serious corrosion to the rolling plate surface, and although acid phosphate has a great improvement in lubricating ability, there are other problems such as corrosion. At present, many professionals have proposed related solutions to the corrosion problem, such as the introduction of different elements, groups. Komatsuozaki S, nakano T, uematsu T, et al, an examination of antiweld film formed by reaction between metal and extreme-pressure agents in metal forming [ J ]. Lubricating Engineering,1985,41 (9): 543-549 Chen Yuanxia, zhou Hai, chen Wenna, etc. Synthesis of oleic acid diethanolamide phosphate and research on rust-proof lubricating property [ J ]. Chemical technology and development, 2008, 37 (3): 10-13Horodysky A G,landisl P S.Borated phosporus-containing compounds and lubricant compositions containing same USA, USP4536306[ P ],1985-08-20.
However, the existing modified phosphate cannot remove aluminum powder well, so that the surface of an aluminum product is easy to blacken, and in addition, the existing phosphate on the market has low emulsifying property, so that a good rolling lubrication effect cannot be achieved. In addition, existing phosphate additives do not have corrosion inhibition capability.

Another advantage of the present invention is to provide a phosphate additive, wherein the phosphate additive can also achieve a bactericidal effect and a certain buffering effect by forming a new amine type phosphate.

Detailed Description
The following description is presented to enable one of ordinary skill in the art to make and use the invention. The preferred embodiments in the following description are by way of example only and other obvious variations will occur to those skilled in the art. The basic principles of the invention defined in the following description may be applied to other embodiments, variations, modifications, equivalents, and other technical solutions without departing from the spirit and scope of the invention.
An additive of phosphate esters according to a preferred embodiment of the present invention will be described in detail below, wherein the structural formula of the additive of phosphate esters is as follows:
wherein the value range of n1 is between 12 and 18; it is worth mentioning that if the carbon chain is too short, the oil film formed is too thin, and lubrication is insufficient; otherwise, if the carbon chain is too long, the residue of the aluminum plate surface treated by the additive is too high, and the subsequent process is difficult.
Furthermore, the radicals R1 are implemented as polyoxyethylene Ethers (EO) or block copolymers thereof with polyoxypropylene ethers (EO-PO-EO), each having the following formula:
preferably, the value of n ranges from 5 to 10, and the value of m ranges from 20 to 50.
It is worth mentioning that the EO number is too small, i.e. if the value of n is too small, the emulsification effect is not obvious; if the EO number is too large, namely if the value of n is too large, on one hand, the improvement of the emulsification effect is not obvious, and on the other hand, the lubrication is insufficient due to the too tight on-site emulsion. More preferably, n has a value in the range of 6 to 8.
Also preferably, wherein m has a value in the range of 30 to 35 or 40 to 45. It is worth mentioning that m is the degree of polymerization of the propylene oxy groups, which may be present in the range of 1 to 200. However, when 20-50 is selected, the emulsification effect is more hydrophilic, so that the emulsification capacity of the oil product in deionized water is improved. In addition, if the polymerization degree is too high, the cost is high and the decomposition and removal are not easy. If the polymerization degree is too low, the emulsification effect is not achieved.
In addition, R is a reaction product of monoethanolamine and formaldehyde, and has a chemical formula:
it is worth mentioning that R is the product of monoethanolamine and aldehydes, which has the function of inhibiting bacterial growth and thus sterilizing. Amines are one of the common types of bactericides that kill bacteria by their denaturing and dissolving effects. The monoethanolamine is consumed too fast in the rolling process, so that the pH drops too fast, and the pH is one of the indexes of greatest concern in the field. So the monoethanolamine can be slowly released by combining with aldehydes substances, thereby achieving a buffering effect, namely, aluminum powder can be removed well and the surface of an aluminum product can be prevented from being blackened easily.

In the following practical examples, the emulsification effect was evaluated by a Markov particle size analyzer, and the smaller the particle size, the better the emulsification effect. The residual amount of the additive was analyzed by TGA thermogravimetry and a simultaneous analyzer volatilization curve, specifically, the lower the residual amount at 300 ℃ was, the better the volatilization was represented. The lubrication effect is evaluated by the friction coefficient shown by the result of the RCP reciprocating tribometer, and the smaller the friction coefficient is, the better the lubrication is proved
