Abstract

The invention relates to an active polyurethane high molecular compound, which can be used in the field of composite materials as a phase separation prevention additive for preventing the phase separation between unsaturated resin and a low shrinkage component. In addition, the compound contains active double bonds that can be crosslinked with the unsaturated polyester in a curing step, thus improving product strength of the composite material.

Description

technical field [0001] The invention relates to an active polyurethane polymer compound, which can be used for dispersing solid particles such as pigments and fillers, such as organic pigments and carbon black, in the fields of general coatings and printing inks. Its greatest feature is that in the field of composite materials, the present invention can prevent the phase separation of unsaturated resin and low-shrinkage components, and at the same time, the active double bond contained in the compound of the present invention can cross-link with unsaturated polyester in the curing stage, thereby Improve the component strength of composite materials. [0002] technical background [0003] Polyurethane chemical products are widely used in the chemical industry as various raw materials, substrates, additives, and finished products due to their diversity of raw materials and diverse reactions. [0004] Polyurethane dispersants have been used commercially, such as BASF EFKA4063, ...
