Abstract
The invention discloses a preparation of a high thermo-resistant fiberglass reinforced PTT composite material, which uses homemade nucleating agent to prepare nucleating agent. The materials by weight percentage of the high thermo-resistant fiberglass reinforced PTT composite material are: 50 to 60 percent of polyester, 0.3 to 1 percent of homemade nucleating agent, 5 to12 percent of bromine flame retardant, 3 to 6 percent of flame retardant synergist, 1 to 6 percent of toughener, 0.1 to 1 percent of anti-oxidant, 0.1 to 1 percent of lubricant, and 30 to 40 percent of fiberglass. The method for preparing the high thermo-resistant fiberglass reinforced PTT composite material is to extrude and granulate polyethylene terephthalate (PTT) which is used as matrix resin and added with the homemade nucleating agent, the bromine flame retardant, the flame retardant synergist, the toughener, the anti-oxidant, the lubricant and the fiberglass through a double-screw. The preparation has the advantages of high thermo-resistant material, normal-temperature injection molding and glossy surface. Because of low cost, the high thermo-resistant fiberglass reinforced PTT composite material can completely replace a fiberglass reinforced PBT composite material and partially replace a fiberglass reinforced PET composite material.

In this patent, use the reason of nucleator: promote crystallization and the crystallization velocity of PTT, and guarantee PTT rapid shaping at normal temperatures at comparatively high temps.
By to learning after the data analysis in the above table, when the self-control nucleator be 0.7% (weight percent) and toughner when being 4% (weight percent) heat resisting temperature reached 210 ℃ for the highest, other over-all propertieies are good.When self-control nucleator usage quantity increases (0.7% is increased to 1.0%) the strength degradation amplitude is bigger, and heat resisting temperature also descends, possible cause is the PTT rapid crystallization, molecular chain arranges that regularity is relatively poor to be caused.And self-control nucleator consumption is less than 0.7% o'clock, intensity and heat-resisting all lower, and to be that PTT degree of crystallinity is low cause possible cause.
More than a kind of heat-resisting glass-fiber provided by the present invention strengthened Poly(Trimethylene Terephthalate) matrix material and preparation method thereof be described in detail, used specific case herein principle of the present invention and embodiment are set forth, the explanation of above embodiment just is used for helping to understand method of the present invention and core concept thereof; Simultaneously, for one of ordinary skill in the art, according to thought of the present invention, the part that all can change in specific embodiments and applications, in sum, this description should not be construed as limitation of the present invention.
