Embodiment 1

[0036] The components of the umbrella frame material of the present embodiment and their weight percentages are:

[0037]

[0038] Among them, the polycarbonate resin is Korean Samsung PC resin, the model is SC-1100R. Polybutylene terephthalate is PBT of Nantong Xingchen, model 1100. The compatibilizer is KW-GE from Shenyang Kewei, and the grafting rate is 3% to 6%. The impact modifier is selected from Dongguan Zhengtong MBS Clearstrength E-920. The antioxidants were 1010 and 168 from Ciba, Switzerland, and the mass ratio of 1010 and 168 was 1:1. The processing aid is EB-FF from Kao, Japan.

[0039] After drying polycarbonate and polybutylene terephthalate at 110°C to 130°C for 3 hours, add compatibilizer, impact modifier, antioxidant and processing aid, mix evenly and add to high-speed mixer , fully mixed for 10 to 20 minutes, and melted and extruded the premixed material in a twin-screw extruder to granulate. The temperature is 250°C, the temperature in the fourth zo...

Abstract

The invention provides an umbrella skeleton material, which comprises the following components in percentage by weight: 49 to 69 percent of polycarbonate resin, 20 to 40 percent of polybutylene terephthalate, 3 to 5 percent of compatilizer, 5 to 10 percent of impact modifier, 0.4 to 0.6 percent of antioxidant and 0.3 to 0.6 percent of processing aid. The invention also provides a method for preparing the umbrella skeleton material. The umbrella skeleton material has excellent performance; the preparation method is simple, and low in cost; and the umbrella skeleton material can serve as an alternative raw material for metal umbrella skeletons.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to an umbrella frame material and a preparation method thereof. Background technique [0002] Polybutylene terephthalate, English name polybutylene terephthalate (referred to as PBT), belongs to the polyester series, which is composed of 1,4-butanediol (1.4-Butylene glycol) and terephthalic acid (PTA) or terephthalate It is a milky white translucent to opaque, crystalline thermoplastic polyester resin formed by polycondensation of dicarboxylate (DMT) and produced through a kneading process. PBT has good weather resistance, low water absorption, maintains various physical properties (including electrical properties, electrical insulation) in humid environments, and is resistant to hot water, alkalis, acids, and oils. Because PBT has heat resistance, weather resistance, chemical resistance, good electrical properties, low water absorption, and good gloss, it is ...
