Abstract

The rubber pipe making process features that it consists of the steps of stoving cloth layer, adhering rubber, cutting and coating the core, and forming. Of the stoved rubber-soaking vinylon fabric, one side is adhered with thin rubber layer and the other side is adhered with rubber in the required thickness; the fabric is then cut based on the size of the rubber pipe and coated onto a pipe core; and the coated fabric is finally sulfurized and settled. The present invention has vinylon fabric to replace cotton cloth, less layers and less cutting times, less material consumption and increased rubber-cloth adhesion.

Description

A kind of manufacture method of sebific duct

Affiliated field:

The present invention is the improvement to the manufacture method that has the canvas filler layer sebific duct.

Background technology:

At present, the fabric hose that uses in the production, its structure is generally inner glue layer, canvas filler layer, outer glue-line and constitutes, also can form the attraction sebific duct in winding steel wire in the middle of the canvas filler layer, its method for production is generally (is example with four layers of folder cloth): glue laminated is prolonged into the thickness that the pipe inner glue layer needs, according to after the severing of sebific duct bore on the tube core encapsulate (being inner glue layer); After cotton dried the two sides rubber, according to the sebific duct bore, severing infantees (if the words of folder steel wire can twine steel wire in the middle of layer of cloth) on inner glue layer one by one one by one; Again glue laminated is prolonged into the thickness that the outer glue of pipe needs, according to wrapping in outside the canvas filler layer after the severing of sebific duct bore; The water of glue-line outsourcing outside cloth to sulfidization molding is freed from the requirement of sebific duct intensity to layer of cloth, from this traditional processing method, there is processing intermediate link comparatively complicated (rubber of twice encapsulate canvas filler layer, repeatedly severing etc.) in its, and consumption glue amount is bigger, waste man-hour, problem such as energy consumption is big.

Summary of the invention:

The objective of the invention is, improve the canvas filler layer material, provide a kind of processing link easy sebific duct manufacture method.

The present invention replaces cotton with the polyvinyl impregnated fabric, because the intensity of polyvinyl cloth is higher than cotton, it can replace two layers of former cotton by one deck.

The key step of this method is: the oven dry of folder cloth, rubberizing, severing Bao Xin, moulding: promptly: the one side of the polyvinyl impregnated fabric after oven dry is pasted thin glue (being equivalent to rubber in the past), another side is according to the thickness rubberizing of the thickness or the outer glue-line of interior glue glue-line, after the severing of sebific duct bore, inner glue layer is simultaneously wrapped in tube core, to have the outside inclusion of the outer glue-line of polyvinyl cloth of outer glue-line (if the middle canvas filler layer that accompanies again can directly add the two sides and pastes the polyvinyl cloth and the method for dependence of thin glue and can add the cotton that thin glue is pasted on one deck two sides) again, deliver to sulfidization molding behind the Bao Yongbu.

The present invention makes the canvas filler layer number reduce owing to replace cotton with polyvinyl cloth, and cutting times reduces, and inside and outside glue directly is attached on the canvas filler layer, has reduced the consumption of material, has increased the tack of glue and cloth.

The specific embodiment:

Under 2.5Kg/cm 100 ' C～state, polyvinyl impregnated fabric oven dry with 20s/5x5, the polyvinyl impregnated fabric that to dry again carries out rubberizing with glue plastering machine, the one side of a slice polyvinyl impregnated fabric is posted 0.2mm glue, another side posts 1.2mm glue as inner glue layer, another sheet polyvinyl impregnated fabric is simultaneously posted 0.2mm glue, another side posts 1.5mm glue as outer glue-line, the polyvinyl cloth that posts glue is carried out severing according to the sebific duct bore, inner glue layer bread on the tube core that coats interleaving agent (if the folder steel wire can twine at this) with the polyvinyl cloth of severing, the polyvinyl cloth that will post outer glue-line again approaches the inside inclusion of glue one side in the outside that wraps in the thin glue of the polyvinyl cloth that has inner gland on the tube core, then looping water cloth is sent into vulcanizing tank at 145C%, 4k9/cm compacted under 35～40 minutes, the cloth of fetching boiling water after the taking-up gets final product.

Claims

1, a kind of manufacture method of sebific duct, it is characterized in that: will press from both sides the cloth oven dry, rubberizing, severing Bao Xin, moulding: promptly: the one side of the polyvinyl impregnated fabric after oven dry is pasted thin glue (being equivalent to rubber in the past), another side is according to the thickness rubberizing of the thickness or the outer glue-line of interior glue glue-line, after the severing of sebific duct bore, inner glue layer is simultaneously wrapped in tube core, to have the outside inclusion of the outer glue-line of polyvinyl cloth of outer glue-line (if the middle canvas filler layer that accompanies again can directly add the two sides and pastes the polyvinyl cloth and the method for dependence of thin glue and can add the cotton that thin glue is pasted on one deck two sides) again, deliver to sulfidization molding behind the Bao Yongbu.
