Abstract
The present invention discloses a new type gear lubricant for small reduction motor system and its preparation method. Its composition includes (by wt%) 5-15% of polyhydric alcohol compounded ester, 50-70% of dibasic acid esters, 5-15% of polyolefine, 5-10% of silicon dioxide powder, 1-3% of diphenyl silicon glycol, 1-3% of acid phosphate ester fatty amine salt, 0.2-1.0% of amine type antioxidant and 1-5% of polytetrafluoro ethylene. The described polyhydric alcohol compounded ester is di-pentaerythritol compounded ester. Said invention also provides the concrete steps of its preparation method and its application.
Description
Technical field
The present invention relates to a kind of lubricant and preparation method thereof, particularly relate to a kind of new gear lubricant that is applicable to multistage, long lifetime, non-maintaining, round-the-clock, low noise low profile gear motor system and preparation method thereof.
Background technology
For satisfying the requirement of present gearing equipment to miniaturization, automation direction development, market is more and more diversified to the demand of incorporate motor and gear reduction system, and performance requriements is also more and more higher:
(1) deceleration system requires low noise: just required the motor bearings low noise in the past, and then low noiseization was also wanted in geartransmission at present, this is particularly outstandingly existing in the household electrical appliance upper body;
(2) mechanical means integral body is little: traditional partly soak formula or the circulating oil lubrication mode can not adopt, and can only be lubricated with the lubricating grease painting type;
(3) step of reduction is more and more: motor output reduces to several rev/mins for thousands of rev/mins, and rotating speed differs greatly, and requirement lubricated, noise reduction is differed greatly, and both will take into account the lubricant requirement very harsh simultaneously;
(4) the Applicable temperature scope is wide: because equipment volume is little, and weak heat-dissipating, continuous operation gear surface temperature can surpass 200 ℃, and also wants under Han Qu-30 ℃ condition and can start rapidly;
(5) long lifetime, non-maintaining: as to require the same life-span of lubricant and equipment, play lifelong lubrication.
, still do not have and use very good product with regard to the lubricant of using in the harsh day by day gear train assembly with regard to present, the low-temperature performance of lubricant and anti-acoustic capability are difficult to take into account.
Summary of the invention
The purpose of this invention is to provide a kind of energy satisfy above require be used for new gear lubricant of low profile gear motor system and preparation method thereof.
Technical scheme of the present invention is to adopt following components in weight percentage: polyvalent alcohol complex ester 5～15%; Dibasic acid esters 50～70%; Polyolefine 5～15%; Silicon dioxide powder 5～10%; Diphenylsilanediol 1～3%; Acid phosphoric acid ester fatty amine salt 1～3%; Amine type oxidation inhibitor 0.2～1.0%; Polytetrafluoroethylene powder 1～5%.Described polyvalent alcohol complex ester is the dipentaerythritol complex ester; Dibasic acid esters is the tridecanyldicarboxylic acid ester; Polyolefine is a polybutene; Acid phosphoric acid ester resin acid amine salt is an octyl phosphate stearylamine salt; Amine type oxidation inhibitor is di-iso-octyldiphenylamine or butyl octyl pentanoic.
In the said components: 40 ℃ of kinematic viscosity of polyvalent alcohol complex ester are 5000～50000cSt; 40 ℃ of kinematic viscosity of dibasic acid esters are 10～50cSt; 40 ℃ of kinematic viscosity of polyolefine are 2000～20000cSt; Amine type oxidation inhibitor is di-iso-octyldiphenylamine or butyl octyl pentanoic.
Preparation process may further comprise the steps successively:
(1) fused: as dibasic acid esters, polyolefine, Diphenylsilanediol to be added in the reactor successively, stir, heat temperature raising to 155 ℃;
(2) viscosifying agent adds: under the agitation condition, 145～155 ℃ of temperature controls slowly add silicon dioxide powder, stir 15min;
(3) grind: taking the dish out of the pot adds all remaining materials after being cooled to normal temperature, grinds three times on triple-roller mill, makes lubricant of the present invention.
Wherein, polyvalent alcohol complex ester weight percentage (%) is: 5,5.5,6,6.5,7,7.5,8,8.5,9,9.2,9.5,10,10.5,11,11.5,12,12.5,13,13.5,14,14.5,15;
Dibasic acid esters weight percentage (%) is: 50,60,65,70%; More progressive dibasic acid esters weight percentage (%) is: 61,62,63,64,65,66,67,68,69.
Polyolefine weight percentage (%) is: 5,10,15; Further weight percentage (%) is: 10,11,12,13,14,15.
Silicon dioxide powder weight percentage (%) is: 5,6,7,8,9,10; Further weight percentage (%) is: 8,8.5,9.
Diphenylsilanediol weight percentage (%) is: 1,2,3; Further weight percentage (%) is: 2,2.5,3.
Acid phosphoric acid ester fatty amine salt weight percentage (%) is: 1,1.5,2,2.5,3;
Amine type oxidation inhibitor weight percentage (%) is: 0.2,0.3,0.4,0.5,0.6,0.7,0.8,0.9,1.0:
Polytetrafluoroethylene powder weight percentage (%) is: 1～5%.
Superiority of the present invention is: it is good that lubricant has a noise reduction effect, is applicable to step-by-step variable gear, satisfies rotating speed from several rev/mins to thousands of rev/mins lubricating requirement; Long lifetime, non-maintaining, with same life-span of equipment, the deficiency that with lubricator need regularly replace before can avoiding; Excellent high temperature performance, general lubricant is used in-10～100 ℃ and has wideer scope, satisfies the round-the-clock demand under-30～200 ℃ of conditions.
