復(fù)合型高分子光穩(wěn)定劑的合成及在劍麻基復(fù)合材料中的應(yīng)用
[Abstract]:During the outdoor use of polymer materials, the long-term exposure to the sun light is easy to take place in the photodegradation reaction. The properties of the materials are gradually reduced, even invalidation and loss of use value. The wood plastic composite material has a series of advantages, such as durable, long life, higher hardness than plastic, better than wood size stability, and with wood plastic composite materials households. In order to prolong the life of the material, it is an effective method to add light stabilizer in the process of preparing materials. The general low molecular light stabilizer is prone to thermal decomposition and volatilization in the process of hot processing, and it is easy to migrate and high marks in the process of use. In this paper, 2,4- two hydroxy two benzophenone (UV0), 2 (2,4- two hydroxyphenyl) 2H- benzo and three azole (UVP), polyglycol monomethyl ether (mPEG2000) and acroleyl chloride can be polymerized by catalytic esterification. Type monomers 2- hydroxyl -4- acrylate based two benzophenone (HABP), 2 (2- hydroxy -4- acrylate based phenyl) 2H- benzo three azole (HAPBT) and polyethylene glycol monomethyl ether acrylate (EGA); polymerizable monomer eighteen alcohol acrolein (OA) was obtained by reaction of eighteen alcohol (SA) with acrylic acid; 2,2,6,6- four methylpiperidine (TMP) was used in catalytic transesterification. Polymerizable monomer 2,2,6,6- four methyl -4- methacrylate base piperidine (MTMP) was obtained from methyl methacrylate, and the product structure was characterized by the reaction of mPEG2000, TMP and maleic anhydride (MAH) with mPEG2000, TMP and maleic anhydride (MAH) by catalytic esterification, and the product was characterized by nuclear magnetic hydrogen spectrum (1H-NMR) and UV spectrum (UV-Vis), and the product was confirmed. The six monomers of habp, MTMP, EGA, OA, tmp-mf-mpeg2000 and styrene (st) are used as raw materials and azo two isobutadionitrile as initiator, and four compound polymer light stabilizers, P (habp-co-mtmp-co-oa-co-ega) containing two benzophenone structures, P (habp-co-mtmp-co-oa), P (habp-co-mtmp-co-ega), are synthesized by solution copolymerization. Mf-mpeg-co-habp-co-st); in addition, with hapbt, MTMP, EGA, OA as raw materials, azo two Ding Jing as initiator, a composite polymer light stabilizer containing benzo and three azole, P (hapbt-co-mtmp-co-oa-co-ega), P (hapbt-co-mtmp-co-oa) and P (hapbt-co-mtmp-co-ega), is synthesized by solution copolymerization. The structure of the synthesized polymer light stabilizer was characterized and its thermal decomposition performance was studied. 6 kinds of polymer light stabilizers were applied to PVC, sisal fiber /pvc, sisal fiber /pp, and sisal fiber /pe polymer to observe UV light stabilization and low molecular light stability. UV-0, UV-P, TMP were added to PVC, sisal fiber /pvc, sisal fiber /pp, sisal fiber /pe, and the artificial accelerated photoaging test was carried out according to gbt1040.4-2006 international standard, through the scanning electron microscope (SEM), tensile properties test, attenuated total reflection infrared (ATR-IR), contact angle test, water extraction experiment, hot pressing. Mobility test and differential scanning calorimetry (DSC) study the law of material damage under photoaging. The results show that high molecular light stabilizers are better than low molecular light stabilizers in the same conditions as low molecular light stabilizers. It is clear that the polymer light stabilizer has better transport resistance than low molecular light stabilizer. Thermal weight loss data shows that high molecular light stabilizer has high thermal decomposition temperature and can obviously improve low molecular light stabilizer, low thermal decomposition temperature, and P (HAPBT-co-MTMP-co-OA-co-EGA) has the highest thermal decomposition temperature. Several high molecular light stabilizers synthesized in this paper have been synthesized in this paper. The results show that the UV light stabilization effect of EGA structure in the copolymer is better than that of the OA structure, while the UV light stabilization effect of the product of the four element copolymerization is better than that of the three element copolymers. The preparation and application have made some beneficial explorations, providing some reference value for the research and application of plastic light stabilizers.
