(X is H).
Present invention also offers a kind of preparation method of the above-mentioned polymer composite for being coated in MDF plate surface: by mass percentage, each component is dropped into mixing kettle mix, the material mixed is undertaken melt extruding mixing by forcing machine, extrusioning mixture material is cooled, with crusher, material is carried out fragmentation, carry out the broken and classification of fine powder with air classifying mill again, finally sieve with rotating screen classification and obtain product.
Beneficial effect of the present invention is: the present invention prepares polymer composite coating, and substantially without chemical reaction below 80 DEG C, package stability is excellent, and store after 2 months under 38 DEG C of conditions, the gel time of product is substantially unchanged; Product adopts high pressure electrostatic painting on the MDF sheet material through mechanical workout or faced deorative, solidified by the type of heating of infrared rays and hot air circulation, condition of cure is 130 DEG C/15min, solidification value is low, production efficiency is high, not easily produce xanthochromia in the curing process, VOC free discharge (simultaneously can be removed the formaldehyde content in MDF sheet material by 130 DEG C of bakings), the sheet material after solidification directly can carry out next procedure installation, saves time.
The present invention adopts terminal carboxyl polyester resin and bisphenol A type epoxy resin; under the effect of curing catalyst 2MA-OK or carbaniloyl,phenylcarbamoyl imidazoles; the carboxyl of epoxide group and vibrin reacts, crosslinked film forming, and the polymer composite impact strength after crosslinked can reach 50kg/cm; snappiness 1mm; sticking power 0 grade, the physical and mechanical properties of organic double compound and ageing-resistant performance excellence, preparation technology is simple; can labor productivity be significantly improved, be applicable to suitability for industrialized production.
Accompanying drawing explanation
Fig. 1 is preparation method's process flow sheet of polymer composite in the present invention.
