Said initiator is according to BPO: the part by weight of dicumyl benzene superoxide=1:1 mixes;
Said whipping agent is a pentane;
Said dispersion agent is a calcium phosphate;
Said tensio-active agent is an X 2073.
Preparing above-mentioned method with expandable styrene copolymerization bead of resistance toheat may further comprise the steps successively:
Earlier water, dispersion agent and tensio-active agent are poured in the reaction kettle, in heating, evenly stirred, process first mixing solutions;
Vinylbenzene, isobornyl methacrylate and initiator are put together, dissolving obtains second mixed solution fully again;
Afterwards, second mixed solution is poured in first mixed solution, and at the uniform velocity stirred, make material form drop with a certain size distribution;
Afterwards, under 88 ~ 92 ℃ temperature, reacted 4 ~ 6 hours;
Afterwards, add whipping agent, and reaction kettle is heated up gradually; When temperature of reaction kettle rose to 138 ~ 142 ℃, constant temperature kept 3 ~ 4 hours;
Afterwards, stop to heat, when temperature of reaction kettle is reduced to 48 ~ 52 ℃, the material in the reaction kettle is taken out;
At last, the moisture in the filtering material, and carry out drying treatment, obtain having the expandable styrene copolymerization bead of resistance toheat.
Take such scheme, have the following advantages:
The expandable styrene copolymerization bead with resistance toheat of taking scheme of the present invention to process, through detecting, second-order transition temperature is up to 110 ~ 120 ℃.Therefore, the porous plastics second-order transition temperature of processing with this expandable styrene copolymerization bead is high, can be used on the higher insulation of temperature and requires occasion, the use occasion broad.
