Abstract: Water-based epoxy resin emulsion was prepared by emulsifying o-cresol formaldehyde epoxy resin with self-emulsified epoxy curing agent synthesized in this study and then used as an environmentally friendly binder for automotive air filter paper. The preparation process of the self-emulsified epoxy curing agent was confirmed by Fourier transform infrared spectroscopy (FTIR). The effects of neutralization degree (Neu) and amount of curing agent on the formation of epoxy resin emulsion were studied. The micro-mor… Show more

In this work, poly-epoxy-acrylate (PEA) resin was prepared by modifying polyacrylate resin with epoxy resin through a simple solution polymerization method. The prepared PEA resin was then neutralized by alkaline treatment to obtain excellent water solubility and used as an ecofriendly binder for automotive oil filter paper. The effect of alkaline neutralization degree on the water solubility of the PEA resin was studied. Also, the influence of epoxy content on the grafting degree of PEA resin was tested. The mechanical strength and oil resistance properties of oil filter paper strengthened by the prepared PEA resin were compared to other commercial binders. The microstructure and pore size of the oil filter paper were observed by scanning electron microscope and tested by capillary flow porometer (PMI), respectively. The results show that the prepared PEA resin can greatly enhance the mechanical and oil resistance properties of the oil filter paper while maintaining its filtration properties. The prepared PEA resin has the potential to be used as an ecofriendly water-based binder for automotive oil filter paper.

The filter paper of automobile engine air filter is easy to temper and causes combustion. Flame retardant is usually added to the reinforced resin styrene-acrylic emulsion (SAE) to improve the flame-retardant performance of the air filter paper. Ammonium polyphosphate (APP) was used as material in this research, and multi-layer coated APP was prepared by microcapsule coating. A layer of nano-scale SiO2 was coated and then introduced organosiloxane structure of the allyl polyoxypropylene ether side chain and boron. The chemical groups and structural composition were determined by Fourier transform infrared spectroscopy. TGA characterized the modified particles' high-temperature stability. By scanning electron microscopy and TEM, the morphologies of modified particles were analyzed to reveal the evolution of modified APP in SAE. Finally, nanoparticles with core-shell structures were formed. Applying the blended resin to the air filter paper, the flame-retardant performance was greatly improved. Total heat release (THR), heat release rate (HRR), peak heat release rate (pkHRR), mass loss rate (MLR), and effective heat of combustion (EHC) were reduced, respectively, by 30.8%, 30.7%, 42.0%, 16.7%, and 14.4%. The time to ignition (TTI) was doubled, so the fire spread could be effectively suppressed. Meanwhile, nano latex particles were attached to the interwoven fibers points and formed a “sea-island structure,” which significantly improved the paper’s mechanical properties, with bursting strength, tensile strength, stiffness, fracture work, and elongation increased by 18.60%, 5.72%, 10.64%, 17.00%, and 81.80%, respectively. It solved the problem that the inorganic flame-retardant particles often lead to the deterioration of the mechanical properties of paper.
