Test result
The result of various tests is presented in table 1～4.
Table 3
Discuss
In the situation of the embodiment shown in table 1 and the table 2 1～4, in mineral oil, added tricalcium phosphate, and changed tensio-active agent.In the situation of embodiment 5～10, tensio-active agent is used with the form of mixture.In the situation of embodiment 11～13, changed the type of base oil.Embodiment 1～13 has shown satisfied lubricating grease state with 227～345 penetration degree.
Can also see that embodiment 1～13 also has excellent thermotolerance, dropping point is all more than or equal to 250 ℃ in every example.
About withstand load, the LNSL (last non seizure load) of embodiment 1～11 is 160kg in the test of four ball extreme pressures, and the LNSL of embodiment 12～13 (last non seizure load) is 126kg.The WL of embodiment 1～10 (sintering load) is 400kg, and the WL of embodiment 11～13 (sintering load) is 315kg.The lubricating grease that is commonly called extreme pressure grease can have the LSNL (last non seizure load) of about 63kg and the WL (sintering load) of about 250kg, thereby described embodiment has shown higher withstand load.
For mechanical stability, the value that embodiment 1～13 shows in the test of shell roller is 262～368, and therefore as seen their mechanical stability is satisfactory.
For water tolerance, be under the situation of 20 weight % in water content, there is no among the embodiment 1～13 get rusty (Figure 1A), and do not observe the destruction of grease structure in the lubricating composition.In addition, penetration degree has shown the value of 287～409 excellence, thereby visible water tolerance is fabulous.
By contrast, comparative example 1～4 does not add tensio-active agent, and penetration degree is 267～272, and dropping point is more than or equal to 250 ℃, is obtaining good result aspect semi-solid state and the thermotolerance simultaneously.
Yet in the test of four ball extreme pressures, the WL of 315kg (sintering load) is good in comparative example 1～4, but the LNSL of 63kg (last non seizure load) has produced the value that significantly is lower than embodiment, thereby withstand load is inferior to embodiment.
In addition, for water tolerance, in all comparative examples 1～4, all generate cherry rust (Figure 1B) on the whole surface of the cylinder 1 of shell roller testing apparatus, interior roller 2 and top cover 3.In addition, the grease structure of lubricating composition destroys, and can not measure penetration degree.Thereby visible comparative example is relatively poor aspect water tolerance.
In the table 4, embodiment 14 is to use the situation of tricalcium phosphate as thickening material, embodiment 15～17th, with tricalcium phosphate and carbamide compound together as the situation of thickening material.Comparative example 5 is to use the situation of carbamide compound as thickening material.
In addition, be 180 hours in the situation centre bearer life-span that tricalcium phosphate or carbamide compound is used alone as thickening material, but bearing life surpass 300 hours when the two uses together, the result is satisfactory.
In addition, for flame retardant resistance, although embodiment 14～17 and unburn (Fig. 2 A), comparative example 5 burnt really (Fig. 2 B).Can see tangible difference, as seen compare that flame retardant resistance is improved with the comparative example 5 of prior art.
