Abstract
The invention discloses a spiral extrusion impregnation technology for an automobile friction sheet. The technology comprises the steps of glue feeding, heating softening, extrusion impregnation and normal-temperature cooling. The technology has the beneficial effects that solvent oil is not required to be used in a production process, so that energy waste is reduced, energy conservation and environment friendliness are achieved, and the technology is safe and reliable.
Description
Technical field
The impregnation moulding process that the present invention relates to composite, is specifically related to the gum dipping process about a kind of spiral squeezing type of automobile friction.
Background technology
Gum dipping process is all the time all that workpiece is directly immersed in and in sizing material, carries out impregnation, this is also had relevant patent as application number be the impregnation as described in 201110150012.9: " scraps of paper are packed in basket, between the scraps of paper, separate with wire netting, basket is sunk to size applicator, size applicator is added a cover fastening, close and open vavuum pump after all pipe valves and vacuumize, vacuum is 0.07～0.08Pa, the time vacuumizing is 15～20 minutes, close vavuum pump and add glue, glue in size applicator is 30% cashew nut oil and 70% absolute alcohol, impregnation 1.5～2 hours, until soak into, open lid, scraps of paper basket is placed in to size applicator top, until the glue-free drop of scraps of paper basket goes out, glue is made up of 30% modified resin and 70% absolute alcohol ".
The gum dipping process of composite fibre is similar to the above, and the filler with solvent naphtha dissolving through mixing fully dissolves in reactor the inside, makes and becomes sizing material.Then sizing material is immersed on composite fibre, and the steam in overbaking tower distills unnecessary solvent naphtha, through charcoal absorption desorb, reclaims the solvent naphtha of 50%-60%.
Above-mentioned gum dipping process has increased the use of solvent naphtha, steam equal energy source, and the feature of environmental protection and safe and reliable poor.
Summary of the invention
The invention provides a kind of novel screw extrusion gum dipping process, described gum dipping process is without using solvent naphtha and steam equal energy source, and therefore its feature of environmental protection and security reliability improve greatly.
The invention provides following technical scheme: automobile wearing piece screw extrusion gum dipping process, its innovative point is, the flow process of described technique is: first carry out sizing material input by streamline, secondly the heating system carrying with screw extruder is carried out thermoplastic, then carry out screw extrusion impregnation, final normal temperature is cooling completes a whole set of technological process.
Further, the linear velocity of the streamline of described sizing material input flow process is 20～50 ms/min.
On this basis, the sizing material softening temperature of described thermoplastic flow process is 80～90 DEG C.
On this basis, the mode of described extruding impregnation is screw extruder extruding impregnation, and spiral squeezing pressure is 18-20 kg/cm, and the effect that applies this pressure is that tree lace 4-8 kg/minute can be extruded in each plastic hole of mould.
Beneficial effect of the present invention: due in production process without use solvent naphtha, therefore reduced the waste of the energy, energy-conserving and environment-protective, safe and reliable.
Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is described in further detail.
Example 1: automobile wearing piece screw extrusion gum dipping process, the flow process of described technique is that sizing material input, thermoplastic, extruding impregnation, normal temperature are cooling.
The linear velocity that described sizing material is thrown in the streamline of flow process adopts 20 ms/min.
The sizing material softening temperature of described thermoplastic flow process is adjusted to 80 DEG C.
The mode of described extruding impregnation is screw extruder extruding impregnation, and spiral squeezing pressure is adjusted to 18 kg/cm.
Example 2: automobile wearing piece screw extrusion gum dipping process, the flow process of described technique is that sizing material input, thermoplastic, extruding impregnation, normal temperature are cooling.
The linear velocity that described sizing material is thrown in the streamline of flow process adopts 50 ms/min.
The sizing material softening temperature of described thermoplastic flow process adopts with 90 DEG C.
The mode of described extruding impregnation is screw extruder extruding impregnation, and spiral squeezing pressure is selected 20 kg/cm.
Example 3: automobile wearing piece screw extrusion gum dipping process, the flow process of described technique is that sizing material input, thermoplastic, extruding impregnation, normal temperature are cooling.
The linear velocity that described sizing material is thrown in the streamline of flow process is 30 ms/min.
The sizing material softening temperature of described thermoplastic flow process is 85 DEG C.
The mode of described extruding impregnation is screw extruder extruding impregnation, and spiral squeezing pressure is 19 kg/cm.
