Abstract

The invention discloses a PTT / PETG composite material and a preparation method therefor. The PTT / PETG composite material comprises the following ingredients, by weight, 40%-60% of PTT, 20%-50% of PETG, 4%-12% of compatilizers, 5%-25% of filling material, 0.5%-2% of light stabilizing agents, 0.1%-0.5% of coupling agents, 0.1%-0.5% of anti-oxidants and 0.1%-1% of lubricants. The filling material is heavy calcium carbonate with a particle size of 10-80nm or silicon dioxide with a particle size of 20-40nm. The beneficial effects are that the PTT / PETG composite material has respective advantages of PTT and PETG, has excellent impact resistance, good heat resistant stability, extremely high ageing resistance and the like, the processability is good, the mechanical properties are excellent, the cost is low, the adaptability is high, and popularization and application are easy.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a PTT / PETG composite material and a preparation method thereof. Background technique [0002] Polytrimethylene terephthalate (PTT) is a polybutylene terephthalate (PET) obtained by polycondensation of terephthalic acid and 1,3-propylene glycol. A promising new polyester polymer material developed after PBT). PTT is a semi-crystalline polymer with high melting temperature and glass transition temperature. It has good mechanical properties, weather resistance, heat aging resistance and hydrolysis resistance. It is widely used in synthetic fibers, films and Engineering plastics and other fields. However, the use of PTT alone has the problems of low notched impact strength and high notch sensitivity, which will greatly limit its application in various fields. PETG is a non-crystalline copolyester that is polycondensed from three monomers of terephthalic acid, ethylene gl...
