Preparation method of heat-resistant and anti-static water-based polyurethane/titanium diboride composite material

Abstract

The invention discloses a preparation method of a heat-resistant and anti-static water-based polyurethane / titanium diboride composite material. Water-based polyurethane and a water-based polyurethane / titanium diboride composite material are sequentially prepared and synthesized; titanium diboride and the water-based polyurethane are compounded so that the heat resistance of the water-based polyurethane can be well improved, the method is simple and efficient, and the synthesis cost is low; meanwhile, the material is endowed with an anti-static function of WPU, and the material can be well applied in the anti-static field. The titanium diboride and the water-based polyurethane are compounded so that the heat resistance of the WPU can be improved, the composite material is also endowed withthe anti-static performance, the problem that the heat resistance of the WPU is poor is solved, the material is endowed with the anti-static performance, and the application range of the material is expanded.

Description

technical field [0001] The invention relates to the technical field of special materials, in particular to the preparation of a heat-resistant and antistatic water-based polyurethane / titanium diboride composite material. Background technique [0002] Polyurethane has become a special material with a wide range of uses and is widely used in coatings, adhesives, sealants, elastomers, etc. Compound (VOC) emissions pollute the environment and endanger human health. Therefore, environmentally friendly water-based polyurethane (WPU) with low VOC emissions has become the main trend in recent decades. [0003] However, because the decomposition temperature of carbamate is around 250°C, WPU usually exhibits relatively low thermal stability; this seriously limits the application of WPU in high temperature fields, so improving the heat resistance of WPU has become a research hotspot. [0004] Titanium diboride (TiB 2 ) as a basic application material is attracting more and more atte...

Problems solved by technology

[0006] At present, the main method to improve the heat resistance of water-based polyurethane is to use components with good heat resistance to carry out compound modification on water-based polyurethane, such as epoxy resin modification, organic silicon modification, silicate modification, acrylate modification, organic Bentonite modification, etc., but there are shortcomings such as complex synthesis, high cost, and single function. Therefore, it is particularly important to solve this type of problem
