Description
Technical field
The invention belongs to rubber industry conveyer belt technical field, and in particular to a kind of heatproof light-type conveyer belt and its preparation side
Method.
Background technology
With flourishing for rubber processing industry, higher wanting is proposed to the conveyer belt as streamline visual plant
Ask.PVC light-type conveyer belts are general with polyester textile as framework material, mainly for delivery of light, middle quality article.PVC is light-duty defeated
Send band with its lightweight, long lifespan, it is easy for installation, be not likely to produce friction the advantages of, be widely used in the industries such as rubber processing.Rubber
Glue product is general after curing all to carry certain temperature, and PVC material is poor as thermoplastic heat resistance, and transport is high
Warm object can cause bad influence to the season cracking of acceleration PVC material, the use to conveyer belt.
Therefore, meeting in the performance basis such as PVC light-type conveyer belts physics and machinery, assigning PVC light-type conveyer belt heatproofs
Function, with very important practical value.Conventional method is to use heatproof plasticizer, instead of conventional PVC plasticizer,
But the usual plasticizing efficiency of heatproof plasticizer is not high, while the thermoplastic feature of PVC material can not be changed, it is impossible to fundamentally improve defeated
Send the heat resistance of band.CPU materials are good with heat resistance as thermosets, and the characteristics of intensity is high, but weight is big, firmly
Degree is high.
The content of the invention
Present invention aim at a kind of high-strength, high-anti-friction light-type conveyer belt is provided, while providing a kind of stably efficient
Manufacture method, with the defect for overcoming existing product to wear no resistance.
The purpose of the present invention can be achieved through the following technical solutions：
The preparation method that the present invention provides heatproof PVC light-type conveyer belts comprises the following steps：
S1：Polyester textile is fixed to framework material；
S2：PVC paste resin is coated with the framework material of step S1, PVC paste resin bottom coating layer is plastified into；
S3：Coating thickness is the composite PVC coating material of 0.9-1.1mm, shape after plasticizing on the PVC paste resin bottom coating layer of S2
Into PVC surface layers；
S4：It is 0.05-0.15mm that reticulation patterns depth is suppressed on the PVC surface layers of S3, and it is poly- to coat poly- carbon type thereon
Urethane glue is simultaneously dried, and obtains the PVC surface layers of patterned；
S5：CPU performed polymers are mixed with curing agent, stir prepared CPU compounds；
S6：The PVC surface layer coating steps S5 of the patterned of step S4 CPU compounds and plastify, the CPU compounds
Thickness be 1.4-1.6mm.
In step sl, it is described to be fixed to be dried and stentering forming by infrared heating.
In step s 2, the plasticizing mode is infrared heating oven heating, 160 DEG C of surface temperature.
In step s3, the plasticizing mode is infrared heating oven heating, 185 DEG C of surface temperature.
In step s 4, the coated weight of the poly- carbon type polyurethane glue is 100g/mm2, 110 DEG C of drying temperature.Add
A small amount of poly- carbon type polyurethane glue, will not both change mechanical performance of the invention, and the PVC of this transmission belt can be greatly improved again
Surface layer and CPU layers of adhesion strength.
In step s 5, the curing agent is 4,4 '-'-diphenylmethane diisocyanate.
In step s 6, the plasticizing mode is infrared heating oven heating, 160 DEG C of surface temperature
The present invention compared with prior art, with advantages below and effect：
1. the CPU on top layer can effective heatproof, it is ensured that conveyer belt does not occur season cracking in use.
2. bottom uses PVC, it is ensured that the soft lightweight of conveyer belt, it is ensured that conveyer belt is in the premise with preferable heat resistance
Under, proportion does not have big rising, it is not necessary to improves conveyer belt driving motor power and expands roller radius, fits conveyer belt
Answer existing equipment, it is not necessary to big transformation is done to existing equipment and be can be used.
The reticulation patterns on 3.PVC surfaces and poly- carbon type polyurethane glue cooperative effect can ensure that CPU is firmly tied with PVC
Close, both separate during preventing use, influence service life.
