Description
Technical field
The present invention relates to field of compound material, more particularly to a kind of thermoplastic pultrusion method.
Background technology
Pultrusion molding process is by the continuous glass fibre beam of impregnating resin glue, band or cloth etc., in the effect of tractive force
Under, it is molded by extrusion die, is solidified, the glass fiber reinforced plastic shapes that continuously production length is not limited.This technique is most suitable for life
Produce the glass fiber reinforced plastic shapes of various section configurations, such as rod, pipe, solid profile (I-shaped, flute profile, squared profile) and hollow section
(door-window section bar, blade).
At present, pultrude process uses thermosetting resin mostly, such as unsaturated polyester (UP), epoxy resin, vinylite,
Phenolic resin etc., solidification process is a process for cross-linking reaction, and what is obtained is thermoset frp, product once sizing not
Shape can again be changed, and be difficult to recycle, environment friendly is poor.Compared with thermoset frp, using thermoplastic resin
Fat prepared thermoplastic's material compound with continuous fiber then can not only overcome these shortcomings, and thermoplastic with more excellent
Good heat resistance and shock resistance, just in consideration of it, thermoplasticity dragging and squeezing glass fiber reinforced plastics are increasingly valued by people in recent years.
The content of the invention
It is an object of the present invention in view of the shortcomings of the prior art, there is provided a kind of thermoplastic pultrusion method.
The technical scheme that is used to achieve the above object of the present invention for：
A kind of thermoplastic pultrusion method, it is comprised the following steps：
1) prepared by impregnant：Thermoplastic polymer resin 70~80%, curing agent 2~5%, silane type coupling agent 0.5~
5.0%th, catalyst 0.5~1%, filler 10~20%, are obtained impregnant at 100~180 DEG C；
2) fiber row yarn：By on the finished fiber one by one row's of being placed on creel, fiber is drawn from tube inwall, and by baking oven
It is dried；
3) dried fiber is after the arrangement of guide web plate by entering dipping tank, held in dipping tank the 1) step prepare
Impregnant；
4) fiber after impregnating is further uniform and removes unnecessary impregnant and bubble, into pre-forming device, makes it
Shape gradually forms the entry shape of shaping mould；
5) curing molding：Enter curing molding equipment after preformed, be made thermoplastic finished product.
Preferably, described catalyst is selected from the one kind in NaOH, potassium hydroxide, sodium hydride, lithium hydride, caustic alcohol
Or several mixtures.
Preferably, described fiber is selected from glass fibre, carbon fiber, quartz fibre, alumina fibre, boron fibre, carbonization
The mixture of one or more in silica fibre or basalt fibre.
Preferably, described curing agent is peroxide.
Preferably, described dipping tank is provided with Extruded roller to control gel content and exhaust, is additionally provided with a point coral plate, will
Fiber after dipping is separated.
Preferably, curing molding equipment is divided into heating zone, gelling area and curing area.
Preferably, described fiber is dried before dipping tank is entered by baking oven, and the temperature of baking oven is 80~100
DEG C, fiber is 3~5 minutes in the residence time of baking oven.
Preferably, the dip time of the 3) step is 10~15 minutes, and the temperature control of dipping tank is prevented at 80~110 DEG C
Only impregnant is cooled and solidified.
The thermoplastic pultrusion method that the present invention is provided, with advantages below and beneficial effect：
1st, in the inventive method, impregnant is good to the dipping effect of fiber, better than powder infusion method and mixing roving
Method, good product performance；
2nd, the inventive method, without solvent recovery operation, saves production cost, and will not make compared with solution dipping method
Into the problem of environmental pollution.
Specific embodiment
As a example by producing glass fiber reinforced polypropylene resin flat sheet, impregnant proportioning is：Acrylic resin 70%,
Hydrogen peroxide (solidfied material) 5%, NaOH (catalyst) 1%, calcium carbonate (filler) 20%, silane type coupling agent 4%.
Concrete technology includes：
1st, said ratio material is put into stirred tank and is well mixed, be then transferred to dehydrating kettle, dipping is obtained at 150 DEG C
Material；
2nd, by the glass fibre one by one row's of being placed on creel, glass fibre is drawn from tube inwall, and carry out by baking oven
Dry, the temperature setting of baking oven is 100 DEG C, and fiber is 5 minutes in the residence time of baking oven, with abundant dry glass fiber；
3rd, dried fiber is after the arrangement of guide web plate by entering dipping tank, held in dipping tank the 1) step prepare
Impregnant；Dipping tank is provided with Extruded roller to control gel content and exhaust, a point coral plate is additionally provided with, by the fiber after dipping
Separate, dip time is 10 minutes, and the temperature control of dipping tank prevents impregnant from cooling and solidifying at 80~110 DEG C；
4th, the fiber after impregnating is further uniform and removes unnecessary impregnant and bubble, into pre-forming device, makes it
Shape gradually forms the entry shape of shaping mould；
5th, curing molding：Enter curing molding equipment after preformed, be made thermoplastic finished product.Curing molding equipment
It is divided into heating zone, gelling area and curing area, is heated using three groups of heating plates on mould and strict temperature control, the temperature of mould
Spend the frictional behaviour of exotherm and material and mould of the Main Basiss resin in solidification and set, temperature is low, and resin is not
Can solidification, temperature is too high, and embryo material solidifies once entering mould, makes shaping, traction all difficult, and waste product can be produced even to damage when serious
Equipment.In heating process, temperature gradually rises resin, viscosity reduction, by the way that behind heating zone, resin system starts to be gelled, consolidates
Change, at this moment product increases with the resistance at mold interface.The boundary condition of zero velocity is broken on wall, the section bar of basic solidification
With uniform speed in die surface fricting movement, basic solidification upon exiting the die, section bar is heated in drying tunnel and continues to solidify,
There are enough curing degrees when ensureing into hauling machine.
Certainly, this invention can also have other to convert, it is not limited to which above-mentioned implementation method, those skilled in the art are had
Standby knowledge, can also various changes can be made without departing from the inventive concept of the premise, such change all should fall in this hair
In bright protection domain.
