Description
Technical field
The present invention relates to the technical field of industry fabric, more particularly to a kind of heat safe impregnation formula.
Background technology
Polyester industry by the use of textile using polyester industrial fiber as primary raw material, polyester industrial fiber is with its high intensity, Gao Mo
The excellent properties such as amount, high temperature resistant have become the main raw material(s) of fabrics for industrial use, mechanical rubber good-rubber conveyer belt, biography
Framework material necessary to dynamic band, rubber hose, at present basic polyesterification.The fusing point of polyester material has good at 264 DEG C
Good heat resistance, therefore polyester dipped canvas has generally substituted previous duck, the application of all kinds of high temperature-resistance conveyor belts
Its powerful advantage is shown in field.
The cinder in power plant, the sintered ore materials of steel plant and slag, and cement plant, smeltery high-temperature material it is defeated
Send, in recent years, with environmental requirement raising and the raising of the degree of automation and conveying capacity, the further extension of fed distance,
Vehicle transport is generally substituted using conveyer belt, therefore in these occasions, High-temperature resistant rubber conveyor belt is to framework material-impregnation
The performance indicator of canvas proposes the requirement of higher：How rubber shoe latex layer is improved under the action of long term high temperature material, rubber shoe latex layer
Rubber ageing-resistant performance.
Therefore, dipped canvas heat resistance is further improved, extends the service life of conveyer belt, is that current solution is high heat-resisting
A conveyer belt problem in the urgent need to address, so as to further promote the development of cloth-reinforced rubber conveyer belt.
The impregnation of current high heat resistance conveyor belt canvas, generally using two-bath process gum dipping process, wherein first bath, using in oneself
The aqueous solution of acid amides blocked isocyanate and epoxy resin handles canvas, but is adopted as the inactive surfaces for improving polyester, the second bath
Fabric, improvement and the bonding force between canvas and rubber are impregnated with the aqueous solution of phenolic resin and VP latex.Occurs resistance to height at present
The main reason for warm nature can be bad is the layer of polyurethane generated after first bath isocyanates self-polymeric reaction, after the vulcanization of rubber,
Under prolonged high temperature action, and the rubber accelerator remnants amines goods and materials reaction of amine, it is decomposed, so as to cause adhesive layer
Damage inactivation.
Therefore the resistance to elevated temperatures of this layer of adhesive layer must be improved, improves the bonding force of rubber shoe latex layer.
The content of the invention
In order to overcome drawbacks described above, it is an object of the invention to provide a kind of impregnation formula for high temperature-resistance conveyor belt.
Wherein, first bath formula includes herein below：
