Abstract

The invention discloses a glass fiber reinforced PC material and a preparation method thereof. The glass fiber reinforced PC material is prepared from, in parts by mass, 70-85% of PC resin, 5-15% of glass fiber, 2-8% of talcum powder, 2-8% of titanium dioxide, 0.1-0.26% of dispersing agent, 0.3-0.7% of anti-UV agent, 0.3-0.65% of antioxidant, 0.085-0.2% of toner, 0.7-2% of delustering agent, 0.9-2.2% of fusion agent, and 1-5% of a toughening agent, wherein the sum of the mass percentages of the components above is 100%. The invention also discloses application of the glass fiber reinforced PCmaterial. The glass fiber reinforced PC material is used for preparing a lower beam track, a guide rail, a warm frame or an interval warm edge strip of the hollow glass built-in shutter. The glass fiber reinforced PC material disclosed by the invention has the characteristics of good rigidity, good temperature resistance, small thermal deformation shrinkage rate, good ultraviolet resistance and small heat conductivity coefficient.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a glass fiber reinforced PC material and its preparation method and application. Background technique [0002] In recent years, in the field of construction, due to the influence of the environment of energy saving and emission reduction, hollow built-in blinds have been widely used. At present, the profiles used in the hollow built-in shutters on the market mainly include two kinds of materials: aluminum alloy and PVC polymer profiles. The thermal conductivity of aluminum alloy profiles is 231-237W / (m*k) at 25°C, and there are problems of high cost, high thermal conductivity, and easy condensation on doors and windows; in addition, the long-term stable use temperature of PVC polymer profiles is -15°C to At 70°C, the thermal deformation shrinkage rate of PVC polymer profiles is 0.1%, and the use stability under extreme conditions is poor, resulting in thermal deformati...
