Description
Technical field
The present invention relates to technical field of polymer materials more particularly to a kind of automobile-used nylon fluorescence interior trim strip material and its systems
Preparation Method.
Background technique
Currently, automobile interior decoration is mostly formed with common plastics and chromium plating edge strip etc., and as automobile industry rapidly develops, user couple
The requirement of automobile interior decoration personalization is higher and higher, is development trend using novel automotive interior material.
2- (6- hydroxyl -3- oxo -3H- xanthene -9- base) benzoic acid is also known as fluorescein, when solar radiation, emits one kind
High intensity visible in addition to general color.
Nylon fluorescent material have good comprehensive performance, including rigidity, toughness, wear resistance, chemical resistance and
Self-lubrication, and coefficient of friction is low, it is easy to process.Non-toxic and non-radioactive, it is reliable and secure for automobile interior decoration.Nylon fluorescent material
Individual character, vigor are shown for automobile interior decoration, meet young Man's Demands.
Summary of the invention
The present invention provides a kind of automobile-used nylon fluorescence interior trim strip material and preparation method thereof.Should the cost of material is low, intensity and
Hardness is good, while having excellent wear.
The purpose of the present invention is achieved through the following technical solutions:
A kind of automobile-used nylon fluorescence interior trim strip material, is prepared by weight by following components:
100 parts of nylon,
0.1-0.5 parts of fluorescent powder,
0.4-1 parts of processing aid,
Further scheme, the nylon are PA6, melt mass flow rate 30-40 (g/ under the conditions of 230 DEG C/2.16kg
10min).Flow rate is lower than this range, then fluorescent powder is difficult to process in system and be uniformly dispersed, and flow rate is higher than this range
Then toughness of material reduces.
The fluorescent powder is 2- (6- hydroxyl -3- oxo -3H- xanthene -9- base) benzoic acid, titanium dioxide, sodium carbonate compounding
It forms.Wherein 2- (6- hydroxyl -3- oxo -3H- xanthene -9- base) benzoic acid fusing point is not less than 126 DEG C；Titanium dioxide, sodium carbonate
Purity is 95% or more.
Titanium dioxide is inert material, has the effect of reinforcing material background color；2- (6- hydroxyl -3- oxo -3H- xanthene -9-
Base) benzoic acid with sodium carbonate can slowly react generation fluorescein sodium, and have intense fluorescence.2- (6- hydroxyl -3- oxo -3H- Xanthones
Ton -9- base) for benzoic acid fusing point not less than 126 DEG C, otherwise temperature capacity is poor, is easier to be precipitated in process, is difficult to disperse.
The processing aid is antioxidant and lubricant.
The antioxidant is N, N '-hexamethylene bis (3,5- di-t-butyl -4- hydroxyl hydrocinnamamide) and phosphorous acid three (2,
4- di-tert-butyl-phenyl) ester compounded；The lubricant is pentaerythritol stearate or lignite wax.
Another goal of the invention of the invention is to provide the preparation method of the above-mentioned nylon fluorescent material for automobile interior decoration,
The following steps are included:
(1) by nylon forced air drying 3-5 hours at 100-120 DEG C.
(2) by weight ratio, first 0.1-0.5 parts of fluorescent powder are sufficiently mixed with 0.4-1 parts of processing aid, then with it is dried
100 parts of nylon be uniformly mixed in a high speed mixer together.Fluorescent powder is first blended with processing aid, the lubrication in processing aid
After agent is blended with fluorescent powder, dispersibility of the fluorescent powder in nylon can be improved, avoid reuniting；Fluorescent powder and lubricant resist
After oxygen agent is blended, dispersion of the antioxidant in nylon may also aid in.
(3) uniformly mixed material is added twin-screw extrude, is squeezed out, is granulated to obtain nylon fluorescent material；It is described
The temperature setting of double screw extruder are as follows: I 180 DEG C of area, 220 DEG C of IIth area, 225 DEG C of IIIth area, 225 DEG C of IVth area, 220 DEG C of Vth area, VI
220 DEG C of area, 220 DEG C of VIIth area, 220 DEG C of VIIIth area, 220 DEG C of the area IX, 220 DEG C of the area X, 225 DEG C of head.
Close to feed opening, temperature is low as far as possible in Ith area, in order to avoid screw rod transmission is influenced, but cannot be too low, in order to avoid influence II area's temperature
Setting；II area's material starts fusion plastification, and caloric receptivity is big, and temperature will improve；IIIth area, IVth area further increase temperature, it is ensured that material
Material melting is completed；Because front melting be basically completed, Vth area, VIth area, VIIth area, VIIIth area, the area IX, the area X slightly reduce temperature, continue by
Material plasticizing is blended uniformly, avoids material overflow；Head raising temperature ensures to discharge smooth.
Compared with prior art, the invention has the following advantages:
Automobile-used nylon fluorescence interior trim strip material prepared by the present invention, the strength of materials and good toughness, fluorescent powder good dispersion,
When solar radiation, the energy of certain form can be absorbed, excitation photon is released the energy of absorption in the form of visible light.It can
It can be by the place of solar radiation for console, steering wheel, sunshading board, air outlet etc..Toner can be cooperated to be made into multiple color.Phase
Common plastics, the chrome-plated material more common than existing automobile interior decoration etc. provide mostly a kind of selection with more personalization, to users.
