PET (Polyethylene Terephthalate) foamed composite board and overhead floor heating system with same
The invention discloses a PET foamed composite board and an overhead floor heating system with the same, and belongs to the technical field of PET foamed composite boards. The PET foamed composite board is prepared from the following components: PET resin, a foaming agent, inorganic filler, a regulator, sodium carboxymethyl cellulose and modified PRS microspheres, mixing the PET resin, the foaming agent, the inorganic filler, the regulator and the sodium carboxymethyl cellulose, and sequentially carrying out melt extrusion and plastic fixing to prepare primary PET; the preliminary PET is smashed and mixed with the modified PRS microspheres, melt blending is carried out through a double-screw extruder, injection molding is carried out under the temperature condition of 270-300 DEG C, rolling and film forming are carried out, and the final PET foaming composite board is obtained. According to the invention, the characteristic that the surfaces of the PRS microspheres have low polarity is utilized to perform resistance modification on a polyester material, and the introduced PRS microspheres are modified to avoid the phenomenon of aggregation of the PRS microspheres to a certain extent, so that the PET foamed composite board has better flame retardance, and the mechanical property of PET is improved.
本发明公开了一种PET发泡复合板材及具有的架空地暖系统，属于PET发泡复合板材技术领域。本发明一种PET发泡复合板材的组成成分包括：PET树脂、发泡剂、无机填料、调节剂、羧甲基纤维素钠、改性的PRS微球；将用所述PET树脂、发泡剂、无机填料、调节剂、羧甲基纤维素钠混合后依次进行熔融挤出、定塑，制得的初步PET；将初步的PET粉碎与改性PRS微球混合，用双螺杆挤出机进行熔融共混，并在270℃～300℃的温度条件下进行注塑并碾压成膜，得到最终的PET发泡复合板材。本发明利用PRS微球表面具备低极性的特点对对聚酯材料进行阻改性，且对引入的PRS微球进行了改性一定程度上避免了PRS微球发生聚集的现象，使得PET发泡复合板材具有较好的阻燃性，提高了PET的机械性能。
