Abstract
The present invention discloses a kind of this preparation of the EPP of automotive sunshade panel, it will be added in heated at high speed mixing machine and be uniformly mixed after various raw material weighings by recipe requirements first, by the raw material prepared by high-temperature heating certain time, form uniform high molecular material mixed liquor, mixed liquor is cooled down at a certain temperature, rapid pressure is put into static pressure machine after cooling to be suppressed, finished product is made, the present invention provides a kind of this preparation of the EPP of automotive sunshade panel, the advantages of with greatly improving production efficiency, ensure that stability.
Description
Technical field
The present invention relates to a kind of this preparations of the EPP of automotive sunshade panel.
Background technique
The EPP ontology of automotive sunshade panel includes left and right two halves, needs to bond left and right two halves in process integral.
Currently, the EPP bulk adhesive of automotive sunshade panel mainly uses manual glue spraying, is then bonded and completed by simple tooling.Due to not having
Have using automation equipment, working efficiency is low, and quality is not guaranteed.
Summary of the invention
The purpose of the present invention is to provide a kind of this preparations of the EPP of automotive sunshade panel, have and greatly improve life
The advantages of producing efficiency, ensure that stability.
The technical scheme is that a kind of this preparation of the EPP of automotive sunshade panel, the automotive sunshade panel
This preparation of EPP include by dissolution of raw material in a solvent, be added filler material mixing after form mixed liquor, then to mold into
Row preheating, makes the surface temperature of mold reach the fusing point of PP, so that mixed liquor is entered mold by spray gun, then steam is passed through
In mold, after being passed through steam, after mould inside reaches certain temperature, cools down, after temperature is reduced to certain temperature, taken off
Modulo operation finally carries out drying and shaping to the product for having taken off mould.
In a preferred embodiment of the present invention, it is 70 DEG C that the temperature, which is reduced to certain temperature,.
In a preferred embodiment of the present invention, it is 140 DEG C that the mould inside, which reaches certain temperature,.
In a preferred embodiment of the present invention, the temperature of the drying is 60 DEG C -80 DEG C.
In a preferred embodiment of the present invention, the raw material is expanded polypropylene, graphene oxide, polyurethane.
In a preferred embodiment of the present invention, the filler material is antioxidant, foaming agent, lubricant.
This preparation of the EPP of a kind of automotive sunshade panel of the invention, has and greatly improves production efficiency, ensure that
The advantages of stability.
Specific embodiment
Below with reference to the preferred embodiments of the present invention will be described in detail, so that advantages and features of the invention can be easier to
In being readily appreciated by one skilled in the art, so as to make a clearer definition of the protection scope of the present invention.
A kind of this preparation of the EPP of automotive sunshade panel of the present invention, this preparation of the EPP of the automotive sunshade panel
Including forming mixed liquor after filler material mixing in a solvent, is added in dissolution of raw material, then mold is preheated, makes mold
Surface temperature reaches the fusing point of PP, so that mixed liquor is entered mold by spray gun, then steam is passed through in mold, is passed through steam
Afterwards, after mould inside reaches certain temperature, cool down, after temperature is reduced to certain temperature, stripping operation is carried out, finally to de-
The product of complete mould carries out drying and shaping.
It further illustrates, it is 70 DEG C that the temperature, which is reduced to certain temperature, and it is 140 that the mould inside, which reaches certain temperature,
DEG C, the temperature of the drying is 60 DEG C -80 DEG C, and the raw material is expanded polypropylene, graphene oxide, polyurethane, the filling
Material is antioxidant, foaming agent, lubricant.
It further illustrates, PP beads is put into kettle and are impregnated under certain temperature and pressure with butane, then unexpected decrease temperature and pressure
Keep its expanded foamed, this method is said simple practical considerably complicated, and PP beads used in infusion process are typically all in kettle
It is produced with tie rod cooling method, low output is again troublesome.Hot cut method production, 1-1.5 millimeters of bead, highly uniform, single machine yield is reachable
150Kg/h or more.(2) high fondant-strength PP and in the investment extruder such as mixture, foaming agent extrusion molding: is added after fusing
(such as butane) keeps its fully dispersed uniformly, squeezes out using cooling from die hole, foam due to being depressured suddenly, cut into time
Beads, in addition chilling and shape.EPP light specific gravity, elasticity is good, antidetonation resistance to compression, Recovery is high, absorbent properties are good, oil resistant,
Acidproof, alkaline-resisting, resistance to various chemical solvents do not absorb water, insulate, heat-resisting (- 40~130 DEG C), non-toxic and tasteless, can 100% recycling
And performance does not almost reduce, is real environmentally friendly foamed plastics.It can be molded in the mold of molding machine with EPP bead
At various EPP products of different shapes.Divide three steps that steam is passed through in mold: steam flush: steam washes away from top to bottom, will
Vaporium, condensed water outflow is discharged in air.In the process, the steam inlet valve of top and the condensed water elimination of lower section are opened
Valve.Lateral steam: make steam swept away on one side to raw material from vaporium, reach another side after penetrating raw material.It closes at this time on one side
Condensation water valve, open steam inlet valve.Meanwhile the steam inlet valve of opposite face is closed, condensation water valve is opened, so that steam
It is sprayed from opposite direction.If there is thin flange in mold, steam is preferably passed through around flange, so as to be clipped in flange
The raw material of the inside also melt by available steaming.Pressure is kept: laterally after logical steam, needing to keep through excess pressure or two-sided steaming was melted
Journey.In the process, steam inlet valve is opened, condensed water elimination valve is closed, pressure is made to progressively reach peak value.
The present invention provides a kind of this preparation of the EPP of automotive sunshade panel, has and greatly improves production efficiency, guarantees
The advantages of stability.
A specific embodiment of the invention, but scope of protection of the present invention is not limited thereto, it is any to be familiar with this field
Within the technical scope disclosed by the invention, changes or replacements that can be thought of without creative work should all be contained technical staff
Lid is within protection scope of the present invention.Therefore, protection scope of the present invention should be to protect model defined by claims
Subject to enclosing.
