Comparative example 8
The overall plastic composite material of ordinary polystyrene described in this comparative example, according to Chinese patent CN102336977B embodiment 1 Preparation.
Experimental example
The foamed polystyrene composite material prepared in above-described embodiment 1-4 and comparative example 1-8 is subjected to boiling water resistance, is resisted Tensile strength and high temperature resistance (150 DEG C/2h, 150 DEG C/6h, 165 DEG C/6h, 180 DEG C/6h, 180 DEG C/12h, 200 DEG C/6h) Test, test method and standard are detected according to the standard of GB17657-2013, and specific structure of testing see the table below 1.
1 foamed polystyrene composite property test result of table
From upper 1 data of table it is found that high temperature resistant co-extrusion type foamed polystyrene composite material of the present invention is with excellent Water boiling resistance, tensile resistance, and variation can be hardly happened on 180 DEG C/6h, the surface 180 DEG C/12h on the whole, had There is the performance used for a long time in 180 DEG C and its following high temperature, the surface of composite material can be had by being continuously heating to 200 DEG C/6h Slight influence has excellent high temperature resistance on the whole.
And lack in the surface layer formula of co-extrusion in comparative example scheme related raw material will lead to final composite material surface it is resistance to Warm nature decline is obvious, is specifically shown in comparative example 1-4.O-cresol formaldehyde epoxy resin in comparative example 1 can mention after hardening for surface layer For the performance of resistance to 200 DEG C or more excellent high temperature；E-20 epoxy resin can not only improve temperature tolerance after hardening in comparative example 2, And since its cementitiousness is outstanding, the binding force of surface layer and sandwich layer can be improved, reduce product table under the environment such as boiling, high temperature The cracking behavior in face；And 1 in comparative example 3,2- cyclohexane cyclohexanedimethanodibasic acid anhydride is the curing agent of epoxy resin, and having lacked it will lead to Surface layer can not solidify, and entire surface layer is thermoplastic film layer, and high temperature resistance is poor, easily shrink, crack at high temperature；Comparison In the surface layer film of fine ceramic powder mixing after hardening used in example 4, due to being inorganic material, high temperature resistant is outstanding, centainly Improve the high temperature resistance of surface layer in degree, but dosage is not easy excessive, the surface layer water boiling resistance performance after otherwise solidifying is poor, easily Dusting.
The foamed polystyrene composite material of existing common non-refractory is mainly polystyrene content, 150 DEG C/2h environment Middle variation less, but can not be resistant to the high temperature of longer time, such as the hot environment of 150 DEG C/6h, it may occur that obvious shrink causes Surface is destroyed, and sees comparative example 8.Comparative example 7 is to prepare high temperature resistant polystyrene by the way of addition fire resistant resin is blended Composite material improves the high temperature resistance of product compared with comparative example 8 to a certain extent, can make material 150/2h, Variation is hardly happened in 150/6h environment, but is dispersed in again since polystyrene blend will lead to part polystyrene resin Is there is obvious shrinkage phenomenon by higher temperature, can not be resistant to higher temperature requirement (>=165 in the surface of condensation material DEG C), special dimension higher for temperature requirement is not available (comparative example 7).
Obviously, the above embodiments are merely examples for clarifying the description, and does not limit the embodiments.It is right For those of ordinary skill in the art, can also make on the basis of the above description it is other it is various forms of variation or It changes.There is no necessity and possibility to exhaust all the enbodiments.And it is extended from this it is obvious variation or It changes still within the protection scope of the invention.
