Problems solved by technology
In the production process, not only the working environment is seriously polluted, but also has an extremely adverse impact on the physical and mental health of the workers, and the management requirements are extremely high. A little carelessness may cause environmental disasters and endanger the lives of the workers; The organic solvent has the effect of promoting aging on the rubber, and has a corrosion and ablation effect on the reinforcement layer which is also an organic substance, which will greatly shorten the service life of the knitted rubber hose
The organic solvent still has the defect of uneven spraying in the spraying process, and there are quality problems such as foaming and delamination.

Embodiment
[0019] Embodiment: The knitted rubber hose production process of the present invention is used in the production of automobile cooling water pipes, and the reinforcing layer is formed by wrapping fibrous polyester wires. The production process of knitted rubber hose includes the following sequential steps:
[0020] 1. Extrusion of inner rubber layer
[0021] The cold feed exhaust extruder extrudes the inner rubber layer at a temperature of 120°C to 130°C and a pressure of 28MPa to 30MPa; the outer diameter of the inner rubber layer is monitored by a caliper gauge in order to adjust the cold feed row in time. Air extruder to ensure that the outer diameter of the inner rubber layer meets the requirements; and then through the cooling of the cooling water tank, the surface hardness of the inner rubber layer can withstand the winding tension of the polyester thread.
[0022] 2. Lay the reinforcement layer
[0023] The knitting machine wraps the polyester thread on the outer peri...

Abstract
The invention discloses a knitting rubber tube production technology. The knitting rubber tube production technology comprises the following steps of: extruding an inner rubber layer, laying an enhancement layer on the peripheral side of the inner rubber layer, coating an outer rubber layer on the peripheral side of the enhancement layer and vulcanizing, wherein yarn ends of the enhancement layer are melt through infrared heating before the step of coating the outer rubber layer on the peripheral side of the enhancement layer is carried out, and then the outer surface of the inner rubber layer is plasticized through hot air heating. The knitting rubber tube production technology has the beneficial effects of being beneficial to environmental friendliness and physical and psychological health of operating personnel, greatly prolonging the service life of knitting rubber tubes, improving the quality of the products and being short in working cycle and high in working performance.
Description
technical field [0001] The invention belongs to the rubber hose manufacturing process in the rubber industry, and in particular relates to a direct bonding process between layers of a knitted rubber hose with a reinforcing layer in production. Background technique [0002] The multi-layer knitted rubber hose with reinforced layer is usually formed by compounding inner rubber layer, reinforced layer and outer rubber layer, and the reinforced layer is mostly knitted or wound with fibers. In the production process of knitted rubber hose, due to the composite reinforcement layer composed of different materials between the inner and outer rubber layers, it is necessary to solve the problem of bonding between layers. The traditional interlayer bonding process is to apply glue after wrapping the reinforcement layer around the inner rubber layer, and then squeeze out the outer rubber layer after the glue dries. This production process has the problems of polluting the working envir...
