Abstract
The present invention provides a kind of process for producing cold cure layer polyurethane repair strip.The present invention includes following production stage: by extruder extrusion single layer polyurethane strips after being dried to humidity lower than 0.07% by polyurethane original packet particle；Its surface of grinding process makes after reaching 38~40 because of value, uniformly applies one layer of Kaimoluoke adhesive；After adhesive parches completely, one layer of cold cure rubber layer of place mat below polyurethane strips, in cold cure rubber layer bottom one layer of high temperature resistance polyester film of place mat, to prevent sticking mould；The good polyurethane strips of place mat and cold cure rubber layer put vulcanizer into simultaneously and carry out vulcanization molding 15~20 minutes at 110 DEG C~120 DEG C, and cold cure rubber layer and polyurethane strips is made to bond together.The present invention is time saving convenient, and the cold cure layer polyurethane repair strip of production increases cold cure rubber layer, and cooperation cold cure glue is superpower bonding with belt, more wear-resisting than conventional repair item, bonding is securely not easily to fall off, tensile strength height, easy to operate.
Description
Technical field
The present invention relates to a kind of processes for producing cold cure layer polyurethane repair strip.
Background technique
Polyurethane repair strip currently on the market is single layer polyurethane strips, is usually all in the damaged conveyer belt of repairing
Apply one layer of common glue carry out simple physical bonds, adhesive strength is poor, even if polyurethane strips bonding plane polish it is crude or
It is adhered directly to above conveyer belt be bonded securely with chemical treatment or physical treatment process, be easy to fall off.
Polyurethane repair strip on existing market is without cold cure layer, if simple with single layer polyurethane strips in the market
Physical bonds cause to repair item it is Nian Jie with conveyer belt insecure or be not easy to be bonded, be easy to fall off.It is repaired using single layer polyurethane strips
It is insecure to mend bonding, and is bonded glue because Qu Rao makes to fall off caused by its is ineffective belt repeatedly, single layer polyurethane repair strip with
The market that conveyer belt bonding problem always affects polyurethane repair strip is universal.
Summary of the invention
The object of the present invention is to provide a kind of cold cure layer polyurethane repair strips, to overcome the above shortcomings.
To achieve the above object, the technical solution of the invention is as follows: a kind of cold cure layer polyurethane repair strip of producing
Process, including following production stage:
A, humidity is dried to lower than 0.07%, then by extruder extrusion single layer polyurethane by polyurethane original packet particle
Item；
B, single layer polyurethane strips are uniform to apply one layer after grinding process surface makes its surface dynes value reach 38~40
Kaimoluoke adhesive；
C, after Kaimoluoke adhesive parches completely, one layer of cold cure rubber layer of place mat under polyurethane strips, in cold sulphur
Change one layer of high temperature resistance polyester film of rubber layer bottom place mat, prevents sticking mould；
D, putting vulcanizer into carries out sulphur at 110 DEG C~120 DEG C simultaneously for the good polyurethane strips of place mat and cold cure rubber layer
Change molding 15~20 minutes, cold cure rubber layer and polyurethane strips is made to bond together.
The layer of polyurethane is that thermoplastic polyurethane particle's extrusion forms.
The beneficial effects of the present invention are: this process is time saving convenient, the cold cure layer polyurethane repair strip of production increases
Cold cure rubber layer is added, cooperation cold cure glue is superpower bonding with belt, has, bonding jail more wear-resisting than conventional repair item
Gu not easily to fall off, tensile strength is high, quickly repairs, easy to operate, saves the time, that is, repairs and use.
Specific embodiment
The present invention includes following production stage: humidity a, is dried to by polyurethane original packet particle lower than 0.07%, then by squeezing
Machine extrusion single layer polyurethane strips out；
B, single layer polyurethane strips are uniform to apply one layer after grinding process surface makes its surface dynes value reach 38~40
Kaimoluoke adhesive；
C, after Kaimoluoke adhesive parches completely, one layer of cold cure rubber layer of place mat under polyurethane strips, in cold sulphur
Change one layer of high temperature resistance polyester film of rubber layer bottom place mat, prevents sticking mould；
D, putting vulcanizer into carries out sulphur at 110 DEG C~120 DEG C simultaneously for the good polyurethane strips of place mat and cold cure rubber layer
Change molding 15~20 minutes, cold cure rubber layer and polyurethane strips is made to bond together.The shape of production is broken according to conveyer belt
What the shape of damage was formulated, typically elongate in shape, but also have a conveyer belt for being used to repair broken hole shape of sheet
Layer of polyurethane is that thermoplastic polyurethane particle's extrusion forms.
Since cold cure layer has tack, to prevent cold cure layer and mold adhesion from needing one layer of high temperature resistance polyester of place mat thin
Film.Since layer of polyurethane is narrower than cold cure layer, therefore one layer of Teflon cloth is put on layer of polyurethane to prevent sticking mould.
The cold cure layer polyurethane repair strip of the application is two-layer compound repairing item, and upper layer is extrusion type polyurethane layer lower layer
For cold cure rubber layer, AB type cold cure glue is smeared when installation, the curing agent in glue sends out cold cure layer
Raw reaction solidification, then allow cured rubber layer and belt to be bonded by the bonding composition in glue, and Nian Jie with conveyer belt autovulcanization,
Reach the features such as time saving convenient and adhesive strength is high, more wear-resisting than conventional repair item.
The above description is only an embodiment of the present invention, is not intended to limit the scope of the invention, all to utilize this hair
Equivalent structure or equivalent flow shift made by bright description is applied directly or indirectly in other relevant technology necks
Domain is included within the scope of the present invention.
