Description
Technical field
A kind of velvet belt that the present invention relates to a kind of on automotive sealant, and in particular to automobile sealed hedge planting of hydrophobic type
Suede band and preparation method thereof.
Background technique
It is how former to the machinery of appearance in automobile use process with automobile gradually popularizing in Chinese society and family
Barrier carry out diagnosis find out reason and give it is appropriate processing it is very important, the appearance of various mechanical breakdowns can be to garage
It sails safety and service efficiency generates significant impact, serious prestige can be constituted to driver and other people person and property safety when serious
The side of body, therefore no matter for maintenance personal or driver, the reason of occurring to automobile mechanical failure carry out Correct Analysis with
It is very important for diagnosis, helps to promote safety and efficiency that automobile uses, better meets the needs of production and living.
The sound is a kind of relatively common automobile mechanical failure extremely, and motorist can be heard when there is this failure
Engine issues dull or sharp sound or other component and issues pause and transition in rhythm or melody sound because of improper friction, this abnormal sound
Sound is alternately present sometimes with certain frequency or interval time, or is intermittently occurred without any rule.
About 70% automobile mechanical failure can all show certain abnormal sound according to statistics, therefore the method by listening attentively to is to vapour
Vehicle mechanical breakdown diagnose it is very useful, with automobile using the time extension and component of machine abrasion quickening, in vapour
When vehicle braking operation due to components agree between gap increase so that work when often there is abnormal sound, by listening attentively to automobile
Abnormal sound can be determined that whether automobile rotation balances, feature when by the way that abnormal sound occurring such as whether it is continuous, with the presence or absence of rule
Whether rule intermittent occurs etc., so that it may the position that primitive decision failure occurs.
Generally, such as the guide groove of vehicle glass, automobile door frame, car trunk or each position of vehicle dormer window are all that can send out
In place of raw abnormal sound.In order to solve abnormal sound, general solution is filled out using the sealing strip or sponge strip of plastics or rubber
It fills in gap and reduces the abnormal sound of automobile.But it reduces not equal to elimination.It is this dynamic during running car
Abnormal sound still can occur, and only can not better solve problem with sealing strip or sponge strip.
At present consciously using flocked pile layer as the wear-resistant coating of sealing strip, but this flocked pile layer be located at this
The contact still defective tightness of automobile window glass on flocked pile layer, especially in car running process, automobile window glass
Vibration of the glass under jacking condition still makes automobile that abnormal sound occur.
Summary of the invention
The reason is that flocked pile layer itself does not have good adhesive force and wearability, make its with automobile window
During glass contact, vibration of the automobile window glass under jacking condition can not be resisted, automobile window glass is caused to rise
Frictional Slipping is generated with flocked pile layer during shock dropping is dynamic, abnormal sound generates therewith.
Electrostatic spinning is to make negative electrical charge on villus band, needs using charge identical charges repel each other the physical characteristic that there is a natural attraction between the sexes
The object of flocking is placed under zero potential or grounding requirement, and villus is attracted by different current potential by flocking object, and perpendicular shape accelerates
It ascends to heaven on by flocking body surface, due to being coated with adhesive by flocking object, villus is just vertically sticked to by plant, because
This electrostatic spinning is the technique generated using the natural characteristic of charge.
The purpose of the present invention is to provide a kind of hydrophobic type weather strip for automobile velvet belts, are able to solve automobile window glass
The abnormal sound problem occurred under jacking condition.
Used technical solution are as follows:
A kind of hydrophobic type weather strip for automobile velvet belt comprising flocking film, flock glue, villus and flock coating, it is described
Flock glue roller coating is sprayed on formation Flock Adhesive water layer on the flocking film, is planted the villus using electrostatic room high-pressure electrostatic
Enter on Flock Adhesive water layer, the flock coating roller coating or is sprayed on the villus and forms flock coating, the flock coating
Including fluorinated silicone modified waterborne polyurethane resin, polyurethane-modified acrylic acid lotion, organic-molybdenum, organosilicon, curing agent and solvent.
In the technical solution of the present invention, the villus is implanted on Flock Adhesive water layer using electrostatic room high-pressure electrostatic and is
A kind of electrostatic flocking technology, electrostatic spinning can be such that villus setting is inserted on glue, and the villus for erectting insertion can be comprehensively
Roller coating or spraying flock coating form flock coating.
In flock coating, fluorinated silicone modified waterborne polyurethane resin has bonding force, also can be improved wear-resisting property, provides
The hydrophobicity of villus；The effect of polyurethane-modified acrylic acid lotion is to increase bonding force, promotion fastness；Organic-molybdenum acts on
Feel in providing the submissive feel of product and sliding；The effect of organosilicon is to adjust product coefficient of friction, raising wear-resisting property, solvent
To dissolution and diluted effect；Curing agent plays the role of crosslinking curing.
To which this flock coating has preferable bonding force, is on the one hand securely attached to coating on villus, separately
On the one hand it can also be securely attached on glass；Again due to wear-resisting property with higher, so as in vehicle glass liter
During drop, the flock coating being attached on glass can bear the intermolecular of the inside between glass and fluosilicic resin and rub
It wipes, solves the problems, such as the abnormal sound occurred under automobile window glass jacking condition.
Fluorinated silicone modified waterborne polyurethane resin is comprising organosilicon or Organic fluoride is monomer modified or the polyurethane of blending and modifying
Resin.
Polyurethane-modified acrylic acid lotion, commercially available acquisition, such as hydroxyl polyurethane modified acrylic acid emulsion D52.

Further, the flock coating further includes defoaming agent.The preferred polyphosphazene polymer siloxane polymer defoaming of defoaming agent
Agent, commercially available acquisition.Such as Digao TEGO825 defoaming agent.The effect of defoaming agent is to eliminate the foam in dispersion process.
Preferably to play flock coating effect, which includes the component of following weight ratio:
Flock coating can be prepared by mixing the above components evenly, flock coating roller coating or be sprayed on villus formed plant
Suede coating.
Flocking film is the base fabric of electrostatic spinning as cloth base material is applied.In the material selection of flocking film, the flocking film can
Preferably one of TPV, PVC, TPE flocking film or a variety of mixing.
The flock glue is applying cloth base material for being bonded villus, is preferably PU water-based flock glue.The water base plant of PU
Suede glue belongs to aqueous adhesive, such as may include modified aqueous polyurethane emulsion, acrylic emulsion, aqueous epoxy resins,
Have the function of that environment-protecting and non-poisonous, water resistance is good, bonding is secured, water-fastness etc..PU water-based flock glue can from the market directly
It obtains.
The villus is preferably PET or PA villus.PET villus, that is, terylene villus；PA villus, that is, nylon villus.PET or
PA villus has preferable wearability.
Another object of the present invention is to provide the preparation methods of the hydrophobic type weather strip for automobile velvet belt of above scheme.
