Problems solved by technology

The use of this composite material is relatively single, and the preparation method is relatively complicated.
[0010] A variety of filled polyurethane-based composite materials have been disclosed in existing patents. The polyurethane matrix is ​​mostly foam type, and the amount of solid filler added can reach 90wt.%, but the added type is single, and most of them are waste coal ash. It can only reduce the cost; the non-foamed polyurethane matrix can add a variety of functional solid particles, but the filling amount is relatively low, only 50-70wt.%. The functional role of the filler cannot be obtained in the composite material. good performance

Abstract

The invention discloses a highly-filled isophorone diisocyanate (IPDI) polyurethane-based composite material, and a preparation method and the use thereof. The components of the highly-filled IPDI polyurethane-based composite material comprises functional solid filler, a polyurethane substrate produced through a reaction of IPDI and oligomer polyol, and other performance adjusting additives. The functional solid filler, the additives and the oligomer polyol are evenly mixed, and then the IPDI is added to an obtained mixture; and the mixture is mechanically kneaded to react and then casted into a die to be cured and formed, so that a product is manufactured. The composite material can be used as a building structure material, a roof waterproof material, a gap repairing material, an energetic blasting material, an indoor decoration material and an insulation material. As the IPDI polyurethane is adopted as the substrate of the composite material, the composite material can be filled with high content of solid filler, which can reach up to 90 wt%, so that the functional effects of the solid filler in the composite material can be greatly played.

Description

technical field [0001] The present invention relates to a highly filled IPDI polyurethane-based composite material, in particular to the polyurethane produced by the reaction of isophorone diisocyanate (IPDI) and oligomer polyols as the matrix material of the composite material to increase the filling capacity of the solid filler , so that the composite material can give full play to the functional effect of the solid filler. The invention also relates to the preparation method and application of the composite material. Background technique [0002] The rapid development of modern industry and the improvement of people's living standards have put forward higher requirements for traditional materials, and the performance of a single material can no longer meet the needs of industrial development and the requirements of people's lives. Filled composite materials based on polyurethane can provide better mechanical properties, wear resistance, weather resistance, solvent resist...
