Description

A kind of composition of low smell cable pulley type electric glass lifter lubricating grease and preparation Method
Technical field
The present invention relates to technical field of lubricating grease, in particular to cable pulley type electric glass lifter lubricating grease and preparation side Method.
Background technique
The electric glass lifter of car is mostly by motor, retarder, conductor rope, guide plate, glass mounting bracket etc. Composition.Because the material or manufacture craft mode of conductor rope are different, and it is divided into three kinds of cable pulley type, cable type and plastics belt electric driven glass Lifter.The first two kind is with wirerope as conductor rope, and latter is with plastic tape as conductor rope.With the cable pulley type electricity generally used For dynamic glass-frame riser, it is made of components such as motor, retarder, wirerope, guide plate and glass mounting brackets, Door glass is fixed in glass mounting bracket when installation, and glass guide groove is parallel with wirerope guide plate.Motor is opened, by Motor driving reducer output power pulls wirerope movable glass mounting bracket, door glass is forced to rise or fall Linear motion.
In the process of running, the position for needing to lubricate mainly has: between 1. wirerope and casing, this lubrication belongs to steel to modeling The friction type for expecting (based on POM, PE liner), mainly has lower coefficient of friction to the performance requirement of lubricating grease, preferable oil Film thickness, preferable mechanical stability and preferable colloid stability prevent grease from low phenomenon occur；It requires to lubricate simultaneously Rouge has good compatibility to plastic parts such as POM, PE, it is ensured that deformation does not occur in lubricant housings；2. wirerope and POM roller Wheel, this lubrication form are similar to wirerope to casing；3. between wirerope and guide plate, this lubricates the friction shape for belonging to steel to steel Formula needs lubricating grease to have excellent wear resistence, preferable oil film thickness, lower coefficient of friction, while lubricating grease being required to have There is preferable anti-medium (water, dust, salt fog etc.), it is ensured that the smooth lubrication of lubricating component；4. the lubrication of slowing-down structure in motor, This lubrication form is primarily present steel to steel, steel to modeling and moulds to three kinds of forms (according to different materials) of modeling, to the property of lubricating grease Can require mainly to have: excellent low-temperature startup, lower operation noise, preferable oil film thickness ensure abrasion, preferable machine Tool stability and colloid stability etc..By the analysis above to lubricant housings, comprehensively consider, PERFORMANCE OF GREASES is required to conclude Be following: excellent resistant of high or low temperature, mechanical stability, extreme pressure anti-wear, colloid stability and rust-preventing characteristic and overlength make With the service life, it is provided simultaneously with environment-protecting and non-poisonous requirement.
The lubricating grease that cable pulley type glass lifter manufacturing enterprise of foreign countries such as Bosch, Bo Ze, extra large moral generation etc. uses at present is equal It can satisfy the service life of resistant of high or low temperature, mechanical stability, extreme pressure anti-wear, colloid stability and rust-preventing characteristic and overlength Requirement, but deposit following problems: there is noise problem in the process of running in 1. cable pulley type electric glass lifters；2. cable pulley type is electric There is Caton phenomenon in varying environment (- 40 DEG C to 80 DEG C) operational process in dynamic glass-frame riser, especially at low ambient temperatures (- 25 DEG C to -40 DEG C) appearance lifting speed is slow, or even not operating condition；3. there is smell after being assembled on lifter in lubricating grease It is pungent, VOC, situations such as poisonous and harmful substance content is exceeded.Domestic cable pulley type glass lifter manufacturing enterprise majority is joint enterprise Industry, there is also the problems same as external grease for the grease used.Certainly will there is an urgent need for research and develop it is a meet performance requirement, together When meet the grease product of (environmentally friendly) requirement of special characteristics again for current to solve on cable pulley type glass lifter Problem.
To reach greasy property requirement, while meeting environment-protecting and non-poisonous evil and requiring, solves following technological difficulties:
1. select the raw material of nonhazardous, by strict control process conditions, it is pungent to solve smell, VOC and toxic has Evil substance excessive problem；
2. solve cable pulley type electric glass lifter there is noise problem in the process of running；
3. solving under cable pulley type electric glass lifter varying environment and Caton and not operation problem occur.
Summary of the invention
The present invention is by selecting product formula chinese raw materials type, the investigation of additional amount, and technique is stringent in preparation process The prepared lubricating grease of control has excellent resistant of high or low temperature, mechanical stability, extreme pressure anti-wear, colloid stability, good Rustless property and the long-life, be provided simultaneously with environment-protecting and non-poisonous requirement.
