Abstract

The invention provides a polyborosiloxane modified polyacrylate foaming material. The polyborosiloxane modified polyacrylate foaming material is synthesized by using an acrylate monomer, a silane coupling agent, hydroxyl-terminated silicone oil, boric acid and an initiator as raw materials. The invention also provides a preparation method and application of the polyborosiloxane modified polyacrylate foaming material. According to the polyborosiloxane modified polyacrylate foam material disclosed by the invention, polyborosiloxane has an excellent energy buffering effect, so that the energy absorption rate of polyacrylate foam can be greatly improved, and the problem of preparation of ultrathin and high-buffering polyacrylate foam in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a polyborosiloxane-modified polyacrylate foam material and its preparation method and application. Background technique [0002] With the development of economy and technology, human beings have more and more needs in industrial production and daily life, and vibration-damping materials are born in response to the needs. Vibration damping materials currently on the market mainly include EVA, PE, CR, PU foam, PORON, D3O, ACF, etc. Acrylate foam is widely used in the field of screen OLED cushioning. [0003] The existing acrylic foams all achieve the purpose of anti-vibration by adjusting the cell structure through technology. For example, Chinese patent document CN209428449U discloses a kind of foam adhesive tape, this foam adhesive tape is foamed through pores, is closed cell state, the size of each hole is the same, the distance between holes is average, has waterpro...
