The present disclosure provides a modifier and a preparation method thereof, and a modified acrylic resin and a preparation method and use thereof, and relates to the technical field of leather auxiliaries. In the present disclosure, the modifier includes an acylate and/or a hyperbranched esterified polymer; where raw materials of the acylate include a first hydroxyl organic amine and maleic anhydride; and raw materials of the hyperbranched esterified polymer include a second hydroxyl organic amine, the maleic anhydride, and an acidic catalyst. The modifier has multiple reactive functional groups such as a hydroxyl group, a carboxyl group, and a double bond. During the preparation of the modified acrylic resin with the modifier, the reactive functional groups in the modifier are copolymerized with a vinyl group of acrylic acid, thereby increasing degrees of branching and crosslinking of the modified acrylic resin.

The present disclosure involves a preparation method of bio-based silica/poly (itaconate-ter-isoprene-ter-glycidyl methacrylate) nanocomposite. Bio-based silica/poly (itaconate-ter-isoprene-ter-glycidyl methacrylate) nanocomposite is environment-friendly, and silica and poly (itaconate-ter-isoprene-ter-glycidyl methacrylate) are derived from non-petroleum base materials, which do not rely on fossil fuel. Compared with nanocomposite without nanocomposite, nanocomposites with glycidyl methacrylate have better silica diffusion, mechanical properties and wet-skid resistance of rubber product are improved while consuming the same time. Further, rolling resistance is decreased so that using silane coupling agent is avoided. Therefore, the processing technology is simplified, and VOC emission is avoided. It is a kind of green tire rubber product.
