Abstract

The invention provides a high-luster and spraying-free PTT/PMMA rearview mirror material and a production technology thereof. The method comprises the following steps: selecting a composite compatilizer system as a compatilizer, and adjusting the proportion of PTT/PMMA to PTT+7.5% PMMA; wherein the processing temperature is 260-280 DEG C. The processing process comprises the following steps: uniformly mixing the raw materials and 5% of compatilizer by a high speed mixer, extruding by a double screw extruder at temperature of 260-280 DEG C, granulating and drying in an air blast drying box with 100 DEG C, and drying for 16 hours to obtain the products. The method can enhance the mechanical property, luster performance and spraying-free performance of the PTT/PMMA material at certain degree, production equipment is easily operated, and the product performance accords with requirements.

Description

A kind of high glaze, exempt from spraying PTT/PMMA rearview mirror PP Pipe Compound and production technology thereof
Technical field
Propose a kind of high glaze herein, exempt to spray production method and the technique of PTT/PMMA rearview mirror PP Pipe Compound, belong to field of high polymer material processing.
Background technology
PTT is the abbreviation of PTT.PTT polyester has than PET and PBT polyester elasticity, dimensional stability and dyeability better, is a kind of new polyester material of excellent performance.Although PTT has excellent performance, because the preparation of its principal monomer 1,3-PD (1,3-PDO) is difficult, cost is high, fail suitability for industrialized production for a long time, have impact on its application.Shell Chemical Co is 1 several years ago, ammediol production technology obtains important breakthrough, production cost reduces greatly, after this said firm steps up PTT production development, the industrialization product trade mark being proposed PTT polyester first with nineteen ninety-five is the PTT product of Corterra, from then on evokes the upsurge of global development.
PMMA is a kind of polymer that optical characteristics and weatherability are all very excellent, and therefore its application concentrates on the external ornament needing visual appearance mostly.Except the purposes such as we common rear vehicle lamp, lampshade, roof, advertising signboard, sheet material, the LED occurred in the eighties in 20th century has also established good start for the application of PMMA in optics.PMMA optical grade moulding compound, because of the transparency, good optical properties, has the performances such as light weight, shock-resistant and easy processing and forming a little, thus can replace unorganic glass.Obtaining extensive use at optical field, is the indispensable materials such as eyeglass, CD, optical fiber, liquid crystal display light guide plate, mobile phone view window.Make the market of liquid crystal display (LED) in recent years increase especially very rapid, optical grade PMMA moulding compound use amount has had and has significantly increased.
The automobile rearview mirror PP Pipe Compound present situation of current extensive use, mostly is ABS or ASA and sprays, and material mostly is the product of BASF, LG, Jin Hu, Qi Mei company.Material carries out
Spraying, can affect the production cycle, increases cost, and is unfavorable for the recycling of product.
The high glaze that this project uses, exempt from spraying PTT/PMMA rearview mirror PP Pipe Compound, company is not also had to adopt the precedent of PTT/PMMA alloy production automobile rearview mirror both at home and abroad, and high glaze, exempt to spray the link that PTT/PMMA material eliminates spraying, processing technology is simple, product integrated cost is also lower than ABS, and material is easy to recycling.
PTT uses mainly as fibrous material, is applied in automotive field also very few as engineering plastics.The Serona product of Du Pont uses now in the air outlet of Toyota Motor, but there are no exempting from the relevant report spraying rearview mirror.
Summary of the invention
The present invention uses maleic anhydride graft ethylene propylene diene rubber as compatilizer, the ratio passing through adjustment raw material PTT/PMMA, adjustment processing temperature and mold temperature, solve in preparation PTT/PMMA composite material with this, the situation that two kinds of materials compatibility are poor, and its high glaze, exempt from spray performance.
preparation method of the present invention comprises the following steps:
1. PTT/PMMA is mixed according to a certain percentage, then add the compatilizer of 5%;
2. raw material, compatilizer are mixed by high-speed mixer, incorporation time is 20s/ time, mixes 3-5 time, mixes;
3. join in double screw extruder by the raw material mixed, adjust to suitable processing temperature, be 260 DEG C-280 DEG C, extrude, by pelleter pelletizing, pelleter rotating speed is 360r/min.Mold temperature is adjusted to 60 DEG C-80 DEG C;
4. the pellet that pelletizing is good is placed in the air dry oven of 100 DEG C, freeze-day with constant temperature 16h;
5. the processing temperature adjusting injection machine is 260 DEG C-280 DEG C, completes the preparation of standard batten, and detects its mechanical property.
