Embodiment approach 1

[0051] (1) Preparation of polycarbonate PC / polystyrene PS blend

[0052] First, mix PS and PC according to the ratio of 7% by mass, take 0.35g of PS and 5g of PC, and then stir under heating and reflux, dissolve PS and PC in 30ml of tetrahydrofuran, and control the temperature between 45 and 55°C; , add 0.16g of tetraethyl orthosilicate TEOS into the dissolving solution, then stir for 10min, then add dropwise acetone and deionized water mixed solution with a pH value of 2.0 into the dissolving solution, wherein, acetone is 0.196g, deionized water It was 0.06g, and then stirred at reflux for 2h to obtain PC / PS gel. After the gel is matured, the solvent is removed; finally, it is dried at 120°C for 2 hours to obtain PC / PS / SiO 2 nanocomposites;

[0053] In the above steps, since the boiling point of tetrahydrofuran is 65.4°C, if the heating temperature is too high or too low, PC and PS will be dissolved unevenly. Therefore, the temperature between 45-55°C is the best; , when i...

Embodiment approach 2

[0068] In the polymer blend alloy, the inorganic substances used as fillers account for less than ten percent. In order to improve the comprehensive performance of polycarbonate, the present invention considers adding inorganic particle nano TiO 2 and nano-SiO 2 to improve its performance. In order to study the influence of the content of inorganic particles on the performance of high polymers, the content of inorganic particles that can improve the comprehensive performance of polycarbonate is optimized by comparison. Therefore, according to the method of embodiment 1, the difference of embodiment 2 is: nano-TiO 2 / SiO 2 Powder and PC / PS / SiO 2 The content ratio of nanocomposite material is 0.5%; In this step of the preparation of polycarbonate / polystyrene blend, PS is 3% of PC, namely 0.15g, and PC is 5g; Tetraethyl silicate is 0.05% g, acetone is 0.15g, deionized water is 0.04g; in nano-TiO 2 / SiO 2 In this step of preparation, tetraethyl orthosilicate is 0.16 g, ammo...

Embodiment approach 3

[0070] According to the processing method of embodiment 1, the difference of embodiment 3 is: nano TiO 2 / SiO 2 Powder and PC / PS / SiO 2 The content ratio of the nanocomposite material is 0.5%. In the preparation step of polycarbonate / polystyrene blend, PS is 15% of PC, that is, 0.75g, PC is 5g; tetraethyl silicate is 0.25g, acetone is 0.25g, deionized water 0.08g; in nano TiO 2 / SiO 2 In this step of preparation, tetraethyl orthosilicate is 0.16 g, ammonia water is 15 ml, and KH550 is 5%.

Abstract

The invention relates to a method for manufacturing glass for vehicle windows by applying polycarbonate-polystyrene blend alloy. The method comprises the following steps: the PC, the PS and the SiO2 are clad to obtain a high polymer, then the TiO2 is clad with the SiO2 to obtain inorganic particles, then the high polymer is fused with the inorganic particles to obtain polycarbonate-polystyrene blend alloy by injection molding, and the polycarbonate-polystyrene blend alloy is applied to manufacturing the glass for vehicle windows and has better ultraviolet resistance, wear resistance and weatherability. The invention is simple and convenient in process, is easy for operational realization and short in period and enables the PC plastic glass for the vehicle windows to be possible in multi-material combination, multi-fitting compounding, multi-color combination and light weighting.

Description

technical field [0001] The present invention relates to a kind of preparation method and application of polycarbonate PC-polystyrene PS blend, especially a kind of adopting sol-gel method to prepare PC / PS blend and nano TiO 2 / SiO 2 The invention discloses a method for making vehicle window glass by blending alloys with powder. Background technique [0002] Due to the outstanding performance of PC, transparent materials for automobiles are no longer the exclusive domain of traditional quartz glass and plexiglass (polymethylmethacrylate). With the improvement of automobile performance, the requirements for transparent materials have become more and more The more demanding, PC materials will gradually occupy the automotive window glass market is the general trend. [0003] Viresyn, launched by TWI in Cambridge, UK, is a low-viscosity liquid formed by traditional dipping, pouring and spraying processes. It is cured with UV light at room temperature to form a scratch-resistant...
