Description
Technical field
The present invention relates to section bar preparation field, particularly relate to a kind of counter-bending colorful co-extruded section and system thereof
Preparation Method.
Background technology
The most PVC co-extrusion section bar, but only one side PVC co-extrusion section bar, such as at the outer wall of section bar
Outer surface forms ASA coextruded layer, or forms colored PVC coextruded layer at the outer wall outer surface of section bar, this
One side co-extrusion section bar has solved section bar alien invasion for weatherability, ornamental requirement, but still does not has
Solve the problem that section bar inner surface color dullness is white, it is impossible to adapt to for building inner surface decorative effect
Requirement.
For overcoming the problems referred to above, Chinese patent CN202187659U discloses a kind of double-colored two-sided PVC co-extrusion
Section bar: described co-extrusion section bar is to have ASA coextruded layer at the outer wall outer surface of section bar, arranges the inwall of section bar
For colored PVC coextruded layer, with ASA coextruded layer, the colored PVC of section bar inwall of described section bar outer wall outer surface
Coextruded layer and cavity constitute two-sided co-extrusion section bar.
Although coextrusion color profile coextruded layer has good weatherability and light resistance, it is possible to well resist certainly
So the erosion of environment, significantly improves the ageing resistace of section bar.But, current colorful co-extruded section,
The infrared reflection rate of ASA coextruded layer is relatively low, result in Surface of profile temperature high, and summer, Surface of profile temperature could
Reaching about 80 DEG C, color coextrusion layer is big with body temperature difference simultaneously, causes section bar to produce bending, reduces door
The closure of window, thermal insulation and serviceability.
Summary of the invention
It is an object of the invention to for technological deficiency present in prior art, and a kind of counter-bending colour is provided
Co-extrusion section bar and preparation method thereof.
Be the technical scheme is that by realizing the purpose of the present invention
A kind of counter-bending colorful co-extruded section, including main body and the color coextrusion layer being formed at body surfaces, institute
Component and the mass fraction of the color coextrusion layer stated be, true qualities ASA or PMMA or PVC 96～98 mass parts
Number；Only reflect ultrared transparent pigment 0.2～1.2 mass fraction；Only the light of infrared spectral range is had
Penetrate cruel cold pigment 0.5～1.5 mass fraction of effect；Common pigments 0.3～1.3 mass fraction.
The described ultrared transparent pigment that only reflects is that particle diameter is at the transparent titanium dioxide of 700nm～900nm.
The cruel cold pigment that described only light to infrared spectral range has transmission effect is that Titanium Dioxide Rutile Top grade is multiple
Close pigment.
Described common pigments is any one or its combination in any of phthalein viridescent, red, blue pigment and ultramarine.
Described main body is PVC or styrene.
The thickness of described color coextrusion layer is 0.1～0.2mm.
A kind of preparation method of counter-bending colorful co-extruded section as claimed in claim 1, it is characterised in that
Comprise the following steps,
1) according to formula precise each component apply batch mixer to premix；
2) premix material is carried out pelletize, obtain color coextrusion raw material；
3) co-extrusion raw material and material of main part co-extrusion are obtained section bar.
Compared with prior art, the invention has the beneficial effects as follows:
The present invention can reduce coextruded layer temperature by adding transparent titanium dioxide reflection infrared ray, reduces heat and amasss
Tired, effectively control the temperature of color coextrusion layer, utilize saturating to the light of infrared spectral range of cruel cold material simultaneously
Penetrate performance, make part infrared ray be irradiated on main body by color coextrusion layer, further reduce colored being total to
Squeeze layer and the temperature difference of main body, it is to avoid it is the most curved that two-layer raw material occurs in various degree flexible and causes
Bent, it is to avoid peeling occurs.Described common pigments is used for adjusting transparent pigment and cruel cold pigment, constitutes
Colored.
Accompanying drawing explanation
Fig. 1 show the counter-bending colorful co-extruded section cross section structure schematic diagram of the present invention.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.Should be appreciated that herein
Described specific embodiment, only in order to explain the present invention, is not intended to limit the present invention.
As it is shown in figure 1, the counter-bending colorful co-extruded section of the present invention includes the main body 2 of PVC material and is formed
At the color coextrusion layer 1 of body surfaces, the thickness of described coextruded layer 0.1～0.2mm, described colour
The component of coextruded layer and mass fraction be, true qualities ASA or PMMA or PVC 96～98 mass fraction；The most anti-
Penetrate ultrared transparent pigment 0.2～1.2 mass fraction；Only the light of infrared spectral range had transmission effect
Cruel cold pigment 0.5～1.3 mass fraction；Common pigments 0.3～1.3 mass fraction.
Wherein, the described ultrared transparent pigment that only reflects can be that particle diameter is at the transparent titanium white of 700nm～900nm
Powder, as producer's Hensel steps the titanium dioxide that model is 800 of production, because it only reflects infrared ray, other light
Color so can be adjusted have little influence on impregnable transmissive by line.Described only to infrared ray
It is Titanium Dioxide Rutile Top grade composite pigment that the light in region has the cruel cold pigment of transmission effect, described cruel cold face
Expect the visible ray of region of ultra-red and near infrared region is had transmission effects, and to major part, nearly 80% can
See that light region and ultraviolet range have reflecting effect.The model produced such as producer BASF be K1010FG or
K2001FG yellow uitramarine, or model is K2795FG brown pigments, or model is the black pigment etc. of 0095,
The present invention can reduce coextruded layer temperature by adding transparent titanium dioxide reflection infrared ray, reduces thermal accumlation,
Effectively control the temperature of color coextrusion layer, utilize the cruel cold material transmittance to the light of infrared spectral range simultaneously
Can, make part infrared ray be irradiated on main body by color coextrusion layer, further reduce color coextrusion layer
Temperature difference with main body, it is to avoid the bending in various degree that two-layer raw material occurs in various degree flexible and causes,
Peeling is avoided to occur.Described common pigments is used for adjusting transparent pigment and cruel cold pigment, constitutes colour
The final color of coextruded layer, it is any one or its any group of phthalein viridescent, red, blue pigment, ultramarine
Close.
Cruel cold raw material only light to infrared spectral range has transmission effect completely and makes more to hold when mixing colours
Easily, the color debugged out is many.Compared to only with common total reflection pigment, its effectively reduce coextruded layer and
While body temperature difference, it is also easy to blend shades of colour, because the total reflection pigment reflection to light
Too strong, covering power is too strong, and this makes when mixing colours, and a lot of colors almost can not be debugged out, it is impossible to full
Foot customer demand, limits its range of application.
