Method for preparing nano titanium dioxide modified polyurethane material and products thereof

Abstract

The present invention discloses one kind of high performance nanometer titania modified polyurethane material and its preparation process. By means of wet chemical technology of preparing nanometer titania powder, the precursor liquid of nanometer titania powder is added into the polyurethane material preparing process, so that the nanometer powder is attached to the surface of other micron levelpigment and stuffing powder inside the polyurethane material. The preparation process includes two steps, including preparing the precursor liquid of nanometer titania powder and modifying polyurethane material with the nanometer titania powder. The modified polyurethane material has obvious nanometer modifying effect.

Description

Technical field The present invention relates to a method for preparing inorganic nano-particle modified polyurethane material. More specifically, the present invention relates to a method for preparing nanometer titanium dioxide modified polyurethane material. At the same time, the present invention also relates to a product prepared by the method; Material science field. Background technique Polyurethane is a new organic polymer material, known as the "fifth largest plastic", because of its excellent performance, it is widely used in many areas of the national economy. Product applications involve light industry, chemicals, electronics, textiles, medical, construction, building materials, automobiles, national defense, aerospace, aviation and other fields. In the polyurethane industry, nano-powders have become a very important additive in polyurethane formulations due to their unique mechanism of action and applicability in many aspects. In technical applications, the dispe...
