Embodiment 1

[0027] The prepared tripropargyl isocyanurate monomer (see the patent document with patent number ZL201010533489.0 for the preparation method) is subjected to DSC test, and the DSC curve obtained by the test is shown in figure 2 , figure 2 Among them, 166°C is the melting point temperature, 248°C is the curing start temperature, 260°C is the curing peak temperature, and 278°C is the curing end temperature. Set the melting and solidification temperature accordingly.

Embodiment 2

[0029] Take 243g of the prepared tripropargyl isocyanurate monomer and place it in a porcelain crucible. In a tube furnace under nitrogen protection, the temperature rises to 166°C at a rate of 10°C / min. Hold for 1 hour under temperature conditions, then heat to 248°C at a heating rate of 1°C / min, and keep it at this temperature for 2 hours, then at a heating rate of 1°C / mim to 260°C, and keep it at this temperature 4h, then increase to 278℃ at a rate of 1℃ / min, keep it at this temperature for 1h and then cool to room temperature.

[0030] The cured resin obtained was characterized by TG for its heat resistance: in N 2 Under the atmosphere, the temperature was increased to 800°C at 10°C / min, and the residual mass of the obtained polymer reached 70%.

Embodiment 3

[0032] Take 243g of the prepared tripropargyl isocyanurate monomer and place it in a porcelain crucible. In a tube furnace under the protection of nitrogen, the temperature rises to 168°C at a rate of 15°C / min. Hold for 1 hour under temperature conditions, then heat to 252°C at a heating rate of 1°C / min, and keep it at this temperature for 2 hours, then at a heating rate of 1°C / mim to 266°C, and keep it at this temperature 4h, then increase to 286℃ at a rate of 1℃ / min, keep it at this temperature for 1h and then cool to room temperature.

[0033] The cured resin obtained was characterized by TG for its heat resistance: in N 2 In the atmosphere, the temperature was increased to 800°C at 10°C / min, and the residual mass of the obtained polymer reached 75%.

Abstract

The invention discloses a tripropargyl isocyanuric ester polymer and a preparation method thereof. The tripropargyl isocyanuric ester polymer is a polymer obtained by melting tripropargyl isocyanuric ester serving as a polymerization monomer at the temperature of 160-170 DEG C and curing at the temperature of 245-300 DEG C with a thermal polymerization method; and the initial decomposing temperature of the tripropargyl isocyanuric ester polymer is 370-385 DEG C. A tripropargyl isocyanuric ester polymer material with a high crosslinking degree can be obtained at a low thermal treatment temperature, the polymer has very high temperature resistance, and starts decomposing at the temperature of 370-385 DEG C in an N2 atmosphere, and the carbon yield can be up to 70-75 percent at the temperature of 800 DEG C.

Description

1. Technical Field [0001] The invention relates to a thermosetting resin and a preparation method thereof, in particular to a tripropargyl isocyanurate (TPIC) polymer and a preparation method thereof. 2. Background technology [0002] Since the 1950s, the development of high technology such as aerospace has promoted the research of heat-resistant polymer materials, and many heat-resistant polymers have been applied one after another. Cyanate resin is a new type of resin with excellent performance. It combines heat resistance, toughness and excellent processability. It has been used in multilayer printed circuit boards, high-speed substrates of optoelectronic devices, radomes, high-speed Gain antennas, stealth aircraft, structural composites and adhesives and many other fields. [0003] Alkynyl resin (ATR) is a new type of high temperature resistant thermosetting resin. Alkynyl resin refers to a terminal alkynyl oligomer or a terminal alkynyl compound. Under certain conditions (su...
